The objective of this environmental document is to inform the City of San Jacinto decision-makers,representatives of other affected/responsible agencies,and other interested parties of the potential environmental effects that may be associated with the proposed project. This Initial Study serves as the environmental review of the proposed project,as required pursuant to the provisions of the California Environmental Quality Act(CEQA), Public Resources Code 21000, etseq.and the State and local CEQA Guidelines. The Initial Study was prepared to identify whether the proposed project will produce significant environmental effects. If an Initial Study prepared for a proposed project determines that no significant effects on the environment will occur or significant impacts can be reduced to less than significant with implementation of mitigation,the Lead Agency can prepare a Negative Declaration or a Mitigated Negative Declaration pursuant to CEQA Guidelines, Sections 15070-15075 et seq. A (Mitigated) Negative Declaration is a statement by the Lead Agency attesting that a project will produce less than significant impacts or significant impacts that can be reduced to less than significant with mitigation. If an Initial Study prepared for a proposed project determines it may produce significant effects on the environment,an Environmental Impact Report(EIR)shall be prepared.This further environmental review is required to address the significant environmental effects of the project and provide mitigation where feasible. Pursuant to the provisions of CEQA and the State and local CEQA Guidelines,the City of San Jacinto is the Lead Agency, and is charged with the responsibility of deciding whether or not to approve the proposed project. A Draft Initial Study and Mitigated Negative Declaration (IS/MND)dated April 5,2011 was circulated for public review on April 14, 2011 for 20-days ending on May 4, 2011. The Notice of Intent and Notice of Availability of the Mitigated Negative Declaration for the proposed project was published in The Press Enterprise on April 14,2011.Comments received on the IS/MND and the City's responses are contained in Section 5 of this Initial Study. Subsequent to the public release of the Draft IS/MND, focused surveys for the burrowing owl were conducted forthe project and the results are contained within Appendix E and for small mammal trapping Appendix F. The proposed project has also been through the Riverside Conservation Authority Public Projects Joint Projects Review (JPA) in compliance with the Western Riverside County MSHCP. The results of the JPA are located in Appendix H. There were changes to Mitigation Measures CUL-01 and CUL-02 that have been made to make the mitigation measure consistent with previous projects that have been approved and implemented bythe City(i.e. Ramona Expressway and Sanderson Avenue Widening Projects).Text was also included to include the results of the burrowing owl and small mammal focused surveys and to clarify what the project is responsible for under the Western Riverside County MSHCP both of which are contained in the Biological Resources section of the IS. Additions of text are noted by the double-underlining of new xt,whereas deletions are shown as strikeout text(old te)d).The revisions were found by the City not to be substantial;therefore,the recirculation of the IS/MND is not warranted. 1.2 FINDINGS OF THIS INITIAL STUDY Pursuant to CEQA and State CEQA Guidelines,this Initial Study has been prepared in order to determine whether implementation of the proposed project will result in significant environmental impacts, which would require the preparation of an EIR. Ramona Expressway Widening Project •Page 1 City of San Jacinto 1.0 Introduction This Initial Study is based on an Environmental Checklist Form (Form), as suggested in Section 15063 (d)(3) of the State CEQA Guidelines.The Form is found in Section 3.1 of this Initial Study. It contains a series of questions about the proposed project for each of the listed areas.The Form is used to evaluate whether or not there are any significant environmental effects associated with implementation of the proposed project. Following the Form in Section 3.2 is an explanation for each answer on the Form. The Form and accompanying evaluation of the responses provide the information and analysis upon which the City of San Jacinto may make its determination as to whether or not an EIR may be required for the project.The Form is used to review the potential environmental effects of the proposed project for each of the following areas: • Aesthetics 0 Land Use Planning • Agricultural Resources 0 Mineral Resources • Air Quality • Noise • Biological Resources Population and Housing • Cultural Resources • Public Services • Geology and Soils a Recreation • Greenhouse Gas Emissions • Transportation and Traffic • Hazards and Hazardous Materials 0 Utilities and Service Systems • Hydrology and Water Quality f Mandatory Findings of Significance 1.3 CONTACT PERSON The Lead Agency for the Initial Study for the proposed project is the City of San Jacinto.Any questions about the preparation of this Initial Study, its assumptions, or its conclusions should be referred to the following: Asher Hartel, AICP, Planning Director City of San Jacinto 595 S.

Project Sponsor's Name and Address: City of San Jacinto 248 East Main Street San Jacinto, California 92583 General Plan Designation: Limited Access Conventional Highway(Sanderson Avenue to San Jacinto Avenue; Urban Arterial (San Jacinto Avenue to Main Street/Lake Park Drive) Zoning: NA Description of Project:The proposed project is the roadway widening of Ramona Expressway between Sanderson Avenue and Main Street/Lake Park Drive.The proposed project would include additional lane expansion,pavement widening, medians,and the extension, relocation, and/or modification of drainage features; and the relocation (as necessary) of utility features. The widening is planned in two phases. Phase 1 consists of improving the roadway segment with addition of two lanes (4 to 6 lanes) between Sanderson Avenue and Eagle Road. The widening will create three lanes of traffic in either direction, a center left-turn pocket or landscaped median and minimal drainage improvements.The improvements will include adjustment and relocation of existing traffic signal poles. Phase 2 consists of adding two lanes from Eagle Road to Main Street(widening the roadway from 2 to 4 lanes).This phase also includes one left-turn pocket or striped median including 5 to 8 feet of paved shoulder, and minimal drainage improvements. This project will also include adjustment and relocation of existing traffic signal poles. Surrounding Land Uses and Setting:The proposed project is in the northern portion of the City of San Jacinto.The land surrounding the project site is mainly rural residential and some commercial between Lyon Avenue and State Street with some retail. The surrounding land between State Street and San Jacinto Street are more urbanized with commercial developments,the San Jacinto Community College campus and residential. Environmental Factors Potentially Affected The environmental factors checked below would be potentially affected by this project, involving at least one impact that is a"Potentially Significant Impact,"as indicated by the checklist on the following pages.

A MITIGATED NEGATIVE DECLARATION will be prepared. 1-1 1 find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a "potentially significant impact` or "potentially significant unless mitigated" impact on the environment, but at least one effect(1)has been adequately analyzed in an earlier document pursuant to applicable legal standards, and (2)has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. ❑ 1 find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required. 4gn, ' e �— S— I re), Signature T Date X S HEX /44/M�-L . 1>474 AJI" JD10e61C-7bA City of San Jacinto Printed Name and Title Lead Agency Ramona Expressway Widening Project •Page 14 City of San Jacinto 3.0 Environmental Checklist Evaluation of Environmental Impacts 1. A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources a Lead Agency cites in the parentheses following each question.A"No Impact"answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved(e.g.,the project falls outside a fault rupture zone).A"No Impact"answer should be explained where it is based on project-specific factors as well as general standards(e.g.,the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis). 2. All answers must take account of the whole action involved, including off site as well as on site, cumulative as well as project-level, indirect as well as direct,and construction as well as operational impacts. 3. Once the Lead Agency has determined that a particular physical impact may occur,then the checklist answers must indicate whether the impact is potentially significant, less than significant with mitigation,or less than significant."Potentially Significant Impact"is appropriate if there is substantial evidence that an effect may be significant. If there are one or more"Potentially Significant Impact" entries when the determination is made, an EIR is required. 4. "Negative Declaration: Potentially Significant Unless Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from"Potentially Significant Impact"to a "Less Significant Impact." The Lead Agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level. 5. Earlier analysis may be used where, pursuant to the tiering,program EIR,or otherCEQA process,an effect has been adequately analyzed in an earlier EIR or negative declaration.Section 15063 (c) (3) (d). In this case, a brief discussion should identify the following: (a) Earlier Analysis Used. Identify and state where they are available for review. (b) Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. (c) Mitigation Measures. For effects that are "Less than Significant with Mitigation Measures Incorporated,"describe the mitigation measures that were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project. 6. Lead Agencies are encouraged to incorporate into the checklist references to information sources for potential impacts(e.g.,general plans and zoning ordinances).Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. 7. Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. 8. This is only a suggested form, and Lead Agencies are free to use different formats; however, Lead Agencies should normally address the questions from this checklist that are relevant to a project's environmental effects in whatever format is selected. 9. The analysis of each issue should identify: (a)the significance criteria or threshold used to evaluate each question; and (b) the mitigation measure identified, if any, to reduce the impact to less than significance.

Does the project have environmental effects which will ❑ ❑ ■ ❑ cause substantial adverse effects on human beings, either directly or indirectly? Ramona Expressway Widening Project .Page 23 City of San Jacinto 3.0 Environmental Checklist 3.2 ENVIRONMENTAL ANALYSIS This section is intended to provide evidence to substantiate the conclusions set forth in the Environmental Checklist. The section will discuss whether or not the proposed project is consistent with the existing General Plan policies and conclusions. 1. AESTHETICS a) Have a substantial adverse effect on a scenic vista? Less Than Significant Impact.The widening of Ramona Expressway will take place within an existing right-of-way.The proposed project is within an area with existing infrastructure, rural residences,single- family homes,agricultural lands,and commercial-retail land uses.According to the City of San Jacinto's (City's)General Plan,unique visual features within the City include topographic features, local flora,and historic buildings. Land uses within the project limits consist of roadway features,moderately urban areas, agricultural lands, and open spaces. Visual characteristics of the project area include views of the San Jacinto Mountains,San Jacinto River, the agricultural lands, golf courses, single family homes, and rural residences. Part of Ramona Expressway passes through the moderately urban developed central area with commercial,retail-service establishments, and San Jacinto Community College campus. As indicated in Figure RM-1 in the Resource Management Element of the City's General Plan, the vistas to the north of the San Jacinto Mountains, Gillman Hot Springs, and Soboba Hot Springs are part of the mountain areas category.The San Jacinto River is part of the Open Space (OS) category and Soboba Springs Country Club is part of Open Space-Recreational (OS-R). The objective of these designations, as stated in the General Plan Resource Management Element is to preserve, protect these important natural resources, and prevent incompatible growth in order to preserve the quality of life. Ramona Expressway is an existing roadway and the proposed project is the widening of this existing infrastructure.The portion of Ramona Expressway from State Street east is not designated as SR-79 but as a local roadway within the City. No portion of SR-79 through the City of San Jacinto has been designated as a scenic route or is identified as being eligible for inclusion in the State Scenic Highway System(State of California 2004). None of these scenic vistas are negatively impacted as a result of the proposed expansion of Ramona Expressway since the widening will occur in existing City right-of-way, which has been designated in the City's General Plan for the widening of Ramona Expressway. In addition Ramona Expressway is an existing major arterial serving the communities of Perris,San Jacinto, Hemet and the mountain communities in the region and will not have an adverse significant effect on a scenic vista. b) Substantially damage scenic resources,including,but not limited to trees,rock outcroppings, and historic buildings within a state scenic highway? No Impact. The proposed project is not located along a state scenic highway and there are no state scenic highways located within the project vicinity. The proposed site does not contain any trees, rock- outcroppings, historic buildings of significance, or other feature that has been identified as a scenic resource by either the City or State. As no impact to an identified scenic resource would result from development of the proposed project, no impact associated with this issue would occur and no mitigation is required. c) Substantially degrade the existing visual character or quality of the site and its surroundings? Less Than Significant Impact.Development of the proposed project would result in the widening of the existing roadway with additional lanes along Ramona Expressway from Main Street to Sanderson Street. Ramona Expressway Widening Project •Page 2¢ City of San Jacinto 3.0 Environmental Checklist The proposed project would not degrade the existing visual character of the site as it is expansion of an existing roadway by addition of two lanes from Sanderson Street to Main Street along Ramona Expressway.Because the proposed project would result in development of features thatfully incorporate established City engineering design criteria, no significant impact related to the change to the existing visual character of the project site would occur and no mitigation is required. d) Create a new source of substantial light or glare that would adversely affect daytime or nighttime views in the area? No Impact.Ramona Expressway is an existing roadway and the proposed project involves widening by additional two lanes.The proposed project does not involve any additional street lighting;therefore,there will be no impact associated with light and glare that could adversely impact daytime and nighttime views and no mitigation is required. ll. AGRICULTURAL RESOURCES a) Convert Prime Farmland, Unique Farmland,orFarmland of Statewide Importance(Farmland) as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resource Agency, to non-agricultural use? No Impact. The California Department of Conservation, Farmland Mapping and Monitoring Program (FMMP),compiles Important Farmland maps pursuant to the provisions of Section 65570 of the California Government Code.These maps utilize data from the United States Department of Agriculture (USDA), Natural Resource Conservation Service(NRCS)soil survey,and current land use information using eight mapping categories and represent an inventory of agricultural resources within Riverside County. The maps depict currently urbanized lands and a qualitative sequence of agricultural designations.Maps and statistics are produced biannually using a process that integrates aerial photo interpretation, field mapping, a computerized mapping system,and public review.Mapping of county farmland categories is conducted every two years. Based on the Riverside County Important Farmland Map(Farmland Mapping and Monitoring Program), portions of lands adjacent to the project alignment are part of farmland of statewide importance, prime farmland and, unique farmland and farmland of local importance. • Prime Farmland: Land that has the best combination of physical and chemical characteristics forthe production of crops. It has the soil quality,growing season, and moisture to produce sustained high yields of crops when treated and managed, including water management, according to current farming methods. • Farmland of Statewide Importance: Land that is similar to Prime Farmland but with minor shortcomings, such as greater slopes or less ability to hold and store moisture. • Unique Farmland:Land of lesser-quality soils used to produce specific high economic value crops.It has the special combination of soil quality, location,growing season,and moisture supply needed to produce sustained high quality or high yields of a specific crop when treated and managed according to current farming methods. It is usually irrigated,but may include non-irrigated orchards orvineyards as found in some climatic zones in California. Examples of Unique Farmland crops include oranges, olives, avocados, rice, grape, and cut flowers. • Farmland of Local Importance: Land of importance to the local agricultural economy, as determined by each county's board of supervisors and local advisory committees, i.e., dairies, dryland farming, aquaculture, and uncultivated areas with soils qualifying for Prime Farmland and Farmland of Statewide Importance. Ramona Expressway Widening Project .Page 25 City of San Jacinto 3.0 Environmental Checklist Farmland of Local Importance in Riverside County is defined as: o Lands with soils that would be classified as Prime and Statewide Farmland but lack available irrigation water. o Lands planted with dryland crops of barley, oats, and wheat. o Lands producing major crops for Riverside County but that are not listed as Unique crops.These crops are identified as returning one million or more dollars on the 1980 Riverside County Agriculture Crop Report. Crops identified are permanent pasture (irrigated), summer squash, okra, eggplant, radishes, and watermelons. o Dairylands, including corrals, pasture, milking facilities, hay and manure storage areas if accompanied with permanent pasture or hayland of 10 acres or more. o Lands identified by city or county ordinance as Agricultural Zones or Contracts,which includes Riverside City 'Proposition R" lands. o Lands planted to jojoba which are under cultivation and are of producing age. The Department of Conservation publishes a Farmland Conversion Report every two years as part of its FMMP.General Plan Figure RM-6 illustrates the Important Farmlands in San Jacinto as identified by the Department of Conservation.The project site is surrounded by Prime Farmland.However,the proposed project is within the existing alignment and right-of-way.The proposed widening is not taking any existing farmland and converting it for the purpose of the expressway expansion. Therefore, there would be no impact related to conversion of prime farmland, unique farmland,farmland of statewide importance and local importance. b) Conflict with existing zoning for agricultural use or a Williamson Act contract? No Impact.The California Land Conservation Act of 1965, also referred to as the Williamson Act, is a non-mandated State program administered by counties and cities forthe preservation of agricultural land. This program enables local governments to enter into contracts with private landowners to restrict specific parcels of land to agricultural or related open space use. In return, landowners receive much lower property tax assessments than normal because the assessments are based upon farming and open space uses rather than full market value. Participation in the program is voluntary on the part of both landowners and local governments, and it is implemented through the establishment of Agricultural Preserves and the execution of Williamson Act contracts. Individual property owners enter into a contract that restricts or prohibits development of their propertyto non-agricultural uses during the term of the contract in return for lower property taxes. Initially signed for a minimum ten-year period, the contracts are automatically renewed each year for a successive minimum ten-year period unless a notice of non-renewal is filed, or a contract cancellation is approved by the local government. Hence,Williamson Act'contracts restrict land development of contract lands. The contracts typically limit land use in contract lands to agriculture, recreation,and open space, unless otherwise stated in the contract.The roadway improvements will occur within existing City right-of- way;therefore,proposed project is not in the Williamson Act Conservation Contract database.2 Because the project site is not part of a Williamson Act contract, no impacts associated with this issue are would occur with the development of the proposed project and no mitigation is required. ' The Williamson Act is a procedure authorized under state law to preserve agricultural lands as well as open space. Property owners entering Into a Williamson Act contract receive a reduction in property taxes in return for agreeing to protect the land's open space or agricultural values. 2 Department of Conservation, Division of Land Resource Protection,Williamson Act Program metadata,2004. Ramona Expressway Widening Project •Page 26 City of San Jacinto 3.0 Environmental Checklist c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code Section 12220(g)),timberland(as defined by Public Resources Code Section 4526), or timberland zoned Timberland Production ( as defined by Public Resources Code Section 51104(g). No Impact. There are no parcels within the City of San Jacinto that are zoned as forest land or timberland. Therefore, the proposed project would not have an impact on forest of timberland and no mitigation is required. d) Result in the loss of forest land or conversion of forest land to non-forest use? No Impact.There is no forest land within the City of San Jacinto.The proposed project will occur within existing City right-of-way; therefore, the proposed project would not have an impact on forest of timberland and no mitigation is required. e) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of farmland to non-agricultural use? No Impact. Please refer to Checklist Questions responses 2(a) and 2(b). The proposed project site currently consists of an existing roadway and City right-of-way. The proposed project construction will occur within the existing City right-of-way;therefore,implementation of the proposed project will not result in the conversion of farmland to non-agricultural use.Therefore, no impact with respect to conversion of agricultural lands to non-agricultural uses would occur and no mitigation is required. III. AIR QUALITY a) Conflict with or obstruct implementation of the applicable air quality plan? No Impact. The proposed project is located within the South Coast Air Basin (Basin) and is within the jurisdiction of the South Coast Air Quality Management District(SCAQMD).The Basin is bounded by the Pacific Ocean to the west and the San Gabriel, San Bernardino,and San Jacinto Mountains to the north and east. It includes all of Orange County and the non-desert portions of Los Angeles,Riverside,and San Bernardino Counties. Basin-wide air pollution levels are administered by the SCAQMD through the Air Quality Management Plan (AQMP).Adopted in June 2007, the AQMP provides a program for obtaining attainment status for key monitored air pollution standards, based on existing and future air pollution emissions resulting from employment and residential growth projections. Because the proposed project is a transportation project, consistency of the project with the AQMP is determined by the Regional Transportation Improvement Program's (RTIP)consistency with the AQMP.This is determined by comparing the emissions from the transportation projects with the emissions budget in the AQMP. If the AQMP growth assumptions are likely to be exceeded as a result of the RTIP improvements, then the RTIP cannot be found consistent with the AQMP. However,since the source of the 2006 RTIP's growth assumptions are the same as the 2007 AQMP, the two documents would be consistent. Several of the RTIP roadway improvement projects provide improved access to areas with existing or anticipated congestion.These projects may be needed due to lack of sufficient roadway capacity or are proposed in local General Plan Circulation Elements as necessary to reduce future congestion anticipated as local General Plans are built out. Because the proposed project is identified in the RTIP and because the RTIP is consistent with the current AQMP, the proposed project is consistent with the AQMP. Therefore, no impacts related to this issue would occur and no mitigation is required. Ramona Expressway Widening Project •Page 27 City of San Jacinto 3.0 Environmental Checklist b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? Less Than Significant With Mitigation Incorporated. Currently, the Basin is designated as a non- attainment area for ozone,PM1o,and PM2,5.Development of the roadway improvements would contribute to air emissions on a short-term basis. Short-term emissions would result from construction activities, such as fugitive dust from grading/site preparation and equipment exhaust. The project is required to comply with regional rules that assist in reducing short-term air pollutant emissions.' The purpose of SCAQMD Rule 403 is to reduce the amount of particulate matter in the atmosphere resulting from man- made fugitive dust sources.Among the requirements under this rule,fugitive dust must be controlled so that the presence of such dust does not remain visible in the atmosphere beyond the property line of the emission source. This is achieved by requiring actions to prevent, reduce, or mitigate dust emissions. Adherence to Rule 403 is a standard requirement for any construction project occurring within the SCAQMD.Construction equipment would emit diesel particulate matter(DPM),a known carcinogen.The cancer risk associated with such exposure is based on a continuous exposure for 70 years. Grading activities for the proposed project is estimated to occur for approximately five to six months. Based on exposure duration and intensity, health risks associated with construction equipment DPM exposure is less than significant. Adherence to Rule 403 with the following construction practices measures, air quality emission impacts associated with construction activities would be less than significant.However, because the Basin is non-attainment for PM10 the use of best available control measures (BACMs) for dust control is required. The following mitigation measures have been identified: Phases 1 and 2 AIR-01 The construction contractor shall ensure that construction grading plans include a statement that all construction equipment will be tuned and maintained in accordance with the manufacturer's specifications. AIR-02 The construction contractor shall use gasoline or electric-powered equipment in lieu of diesel-powered engines where feasible. AIR-03 The construction contractor shall ensure that construction grading plans include a statement that work crews will shut off equipment when not in use to reduce excessive idling. The construction contractorshall also ensure that use of heavy construction is suspended during first stage smog alerts. AIR-04 The construction contractor shall be encouraged to use"clean diesel"equipment if modified engines (catalyst equipped or newer Moyer Program retrofit) are available at a reasonable cost. AIR-05 The construction contractor shall implement best available control measures(BACMs)during grading to reduce fugitive dust emissions during construction. The BACMs to be implemented include, but are not limited to,the following: • Water all active construction areas three times daily; • Cover all haul trucks or maintain at least 2 feet of freeboard; • Pave or apply water four times daily to all unpaved parking or staging areas; • Reduce speed on unpaved roads to less than 15 mph; • Sweep or wash any site access points within 30 minutes of any visible dirt deposition on any public roadway; Ramona Expressway Expansion Air Quality Study, RK Engineering Group Inc.,April 2009. Ramona Expressway Widening Project •Page 28 City of San Jacinto 3.0 Environmental Checklist • Cover or water twice daily any on-site stockpiles of debris, dirt or other dusty material; • Suspend all operations on any unpaved surface if winds exceed 25 mph; and • Hydroseed or otherwise stabilize any cleared area which is to remain inactive for more than 96 hours after clearing is completed. AIR-06 The construction contractor shall support and encourage the following additional recommendations to help reduce impacts to the surrounding community: • Encourage car pooling for construction workers; • Limit lane closures to off-peak travel periods; • Park construction vehicles off traveled roadways; • Wet down or cover dir hauled off-site; • Wash or sweep access points daily; • Encourage receipt of materials during non-peak traffic hours; • Sandbag construction sites for erosion control; and • Participation in any City adopted Transportation Demand Management(TDM)programs. Adherence to these measures would reduce short-tenn air quality impacts associated with construction to a less than significant level. No further analysis is required. c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? Less Than Significant Impact.Currently,the Basin is designated as a non-attainment area for ozone, PM10, and PM2.5. Air pollution levels of the criteria air pollutants are monitored, or measured, by the applicable district at various locations throughout the Basin. Although the proposed project is within a non-attainment area for Federal and State ozone, PM2.5, and PM10 standards, the Environmental Protection Agency(EPA) does not require hot-spot analysis, qualitative or quantitative, for projects that are not listed as an air quality concern. The proposed project would improve roadway operations by reducing traffic congestion and improving traffic operations and would not introduce a new source of ozone, PM2.5, or PM10. Therefore, the proposed project would not create a new, or worsen an existing, ozone, PM10, or PM2.5 violation. Impacts associated with this issue are considered to be less than significant and no mitigation is required. d) Expose sensitive receptors to substantial pollutant concentrations? Less than Significant Impact.Sensitive receptors are defined as populations that are more susceptible to the effects of pollution than the population at large.The SCAQMD identifies the following as sensitive receptors: long-term healthcare facilities,rehabilitation centers,convalescent centers,retirement homes, residences,schools,playgrounds,childcare centers,and athletic facilities.There are residential uses and a community college along segments of the proposed project; however, emissions generated from the proposed project are below those identified by the SCAQMD with implementation of the identified mitigation measures and would not expose sensitive receptors to substantial pollutant concentrations. Therefore, impacts related to this issue are anticipated to be less than significant and no further analysis is required. Ramona Expressway Widening Project •Page 29 City of San Jacinto 3.0 Environmental Checklist e) Create objectionable odors affecting a substantial number of people? Less than Significant Impact.During construction,the various diesel-powered vehicles and equipment in use on the site may create odors from exhaust emissions.Additionally,the installation of asphalt may generate odors. These odors are temporary and not likely to be noticeable beyond the project boundaries. SCAQMD standards regarding the installation of asphalt surfaces are sufficient to reduce temporary odor impacts to a less than significant level. The proposed project is widening an existing roadway,which is not anticipated to generate long-term objectionable odors.Therefore, impacts related to creation of objectionable odors affecting substantial numbers of people would to be less than significant and no mitigation measures are required. IV. BIOLOGICAL RESOURCES A General Biological Resources Assessment and MSHCP(Multiple Species Habitat Conservation Plan) Consistency Report was prepared for the proposed project by LSA Associates, Inc. in December 2010 and Burrowing Qwl survey conducted in May 2011 and sMall mammal trapping conducted July 10-25 in accordance to the Western Riverside County MSHCP guidelines.The following answers to the questions are based on the findings in these reports. a) Have a substantial adverse effect,either directly or indirectly or through habitat modification, on any species identified as a candidate,sensitive,or special status in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service?

Eight Special Interest Species not fully covered by MSHCP have a low potential to exist on the site. Coulter's saltbush(Atriplex coulten), Plummer's mariposa(Calochortus pfummerae),Davidson's saltscale(Atriplex serenana var. davidsonii),thread-leaved brodiaea(Brodiaea fififolia), mud nama(Nama stenocarpum), San Bernardino aster(Symphyotrichum defoliatum), western mastiff bat(Eumops perotis), and western yellow bat (Lasiurus xanthinus) have a low potential to be present on the site based on existing conditions. The existing soils types are known to support narrow endemics and criteria are plant species that could occur in the project area. However, these soils are highly disturbed. The project site is not within the MSHCP Narrow Endemic Plant Species Survey Area(NEPSSA) or Criteria Area Species Survey Area (CASSA) of the MSHCP. Therefore, no surveys for NEPSSA or CASSA are required. The following mitigation measures have been identified to reduce the significance of potential impacts to the burrowing owl species and small mammals.Adherence to Mitigation Measures BIO-01 through BIO- 10 would reduce impacts associated with these species to a less than significant level. Phases 1 and 2 BIO-01 All vegetation clearing,tree removal activities,or tree trimming activities shall occur outside of the nesting bird season(February 15—August 31). In the event that vegetation clearing is necessary during the nesting season, a qualified biologist shall conduct a pre-construction survey to identify the locations of nests. Should nesting birds be found, the biologist shall establish an exclusionary buffer. This buffer shall be clearly marked in the field by construction personnel under guidance of the biologist,and construction orclearing shall not be conducted within this zone until the biologist determines that the young have fledged or the nest is no longer active. BIO-02 Trenches and holes shall be inspected for entrapped wildlife each morning priorto the onset of construction. Holes and trenches shall be thoroughly inspected by qualified permitted biologist for entrapped animals prior to the holes and trenches being filled. Any animals discovered shall be removed from the trench or hole by a qualified biologist and released. BIO-03 A pre-construction burrowing owl survey shall be conducted by a qualified biologist within 30 days priorto ground-disturbing activities for each phase of construction in order to determine whether any burrowing owls are occupying potentially suitable desert scrub habitat. If Ramona Expressway Widening Project •Page 31 City of San Jacinto 3.0 Environmental Checklist surreys determine that burrowing owls occupy the site,a burrowing owl mitigation plan shall be prepared, subject to approval by the California Department of Fish and Game (CDFG). Mitigation measures identified in the plan shall include: Burrows located outside the project area (within 250 feet) shall be flagged for avoidance. Unoccupied burrows located in the project area shall be covered to prevent owls from reoccupying the burrows prior to construction. • If active owl burrows are discovered within 250 feet of proposed work areas, the owls shall be relocated from the burrows using either active or passive techniques as recommended by the CDFG. Owl relocation, as well as discouragement of owls from returning to the site, shall occur in the following manner: 1) During the non-breeding season(September 1 through January 31),burrowing owls occupying proposed work areas shall be evicted by passive relocation. Passive relocation shall include the installation of one-way doors on burrow entrance. Any active burrow shall be replaced off-site in adjacent habitat with an artificial burrow. Burrows shall be inspected with a fiber optic camera to ensure animals do not remain in the den. 2) If construction is scheduled during the breeding season(February 1 through August 31) and prior to the relocation of the owls, a 250-foot protective buffer shall be maintained around burrows occupied by owls until the young have fledged. Other actions could include passive relocation if it is determined that owls have not begun laying eggs or postponement of construction in the area until the young are fledged and no longer dependent upon the nest burrow. 3) Once fledglings are capable of independent survival and adult non-breeding owls have successfully been relocated off site, potential owl burrows shall be collapsed in order to keep the owls from returning. Phase 2 only BIO-04 Trapping shall be conducted for-MSHCP small mammal survey species within 30 days prior to ground-disturbing activities associated with the project.Trapping shall be conducted by a permitted biologist using standard protocol measures associated with SBKR,) and other sensitive mammal species. The area within the exclusionary fence shall b trapped for a maximum of 8 nights and any trapped animals shall be relocated to suitable habitat outside the fenced construction limits in previously constructed artificial hllrrnw. _he exGlus*GR. y tFappipg e#GFt shall he n9n.'a...:.`.:.ed such a way that WGFfnatieR re9aFdiRg4,he. the effert shell be ..eatable a4_r.reinni The a 'thin the PxGl,i igRaFy feRGe Shall I SBKR trapped shell be ...erl.ed by elinning their fur to Identify them if 'nrliv'.'1. ..Is a Fe FesaPtWFGd. BIO-05 Prior to project construction, a 4-foot high, and 0.5-inch temporary steel mesh-Ssmai mammal exclusionary fence shall be placed along the right-of-way limits where suitable SBKR habitat exists, as determined by a qualified permitted biologist. The bottom of the exclusionary fence shall be buried belowground a minimum depth of 12 inches to minimize the potential that SBKR can re-enter the construction area and to preclude impacts to adjacent habitat. B1O-06 The temporary small mammal RRKR exclusionary fence shall be maintained in place throughout the duration of construction in these areas to minimize take of LAPM SBKR Ramona Expressway Widening Project •Page 32 City of San Jacinto 3.0 Environmental Checklist during the construction phase and preclude the inadvertent disturbance of outlying areas by construction personnel.Access to LA2K49149 habitat outside of the construction limits shall be prohibited and posted accordingly.Because LA2USEKR are nocturnal,the exclusionary fence shall be inspected daily by qualified permitted biologist before dusk and shall be repaired as necessary so that there are no gaps greater than 0.5 inch on any portion of the fence that could allow LARML89449 entry into the project area. BIO-07 Within construction limits in any potentially suitable habitat for LAP1b189KRinor adjacent to San Jacinto River,the construction contractor shall ensure that all excavated, steep-walled holes or trenches more than 2 feet deep are covered at the close of each working day with plywood or provide one or more escape ramps constructed of earth fill or wooden planks to prevent entrapment of LAPIv during construction.The ramps shall be located at no greater than 100-foot intervals, with slopes less than 45 percent, and be at least 1 foot in width. BIO-08 All construction pipes, poles, culverts, or similar structures with a diameter of 1.5 inch or greater stored at a construction for one or more overnight periods shall be thoroughly inspected by qualified permitted biologist forthe presence of LAPM SEIKR before the pipe is subsequently buried,capped,or otherwise used or moved in any way. Unburied pipes laid in trenches overnight shall be capped. If LAM are discovered inside a pipe,the section of pipe where the LAPM 4139R is discovered shall not be moved until a qualified biologist has been consulted. If necessary and under the direct supervision of a qualified biologist,the pipe may be moved only once to remove it from the path of construction activity until the animal has been removed and released. BIO-09 A qualified biological monitor shall be present during ground-disturbing activities within suitable habitat for LAPwL491414. The monitor shall have the authority to stop activities should it be required to avoid take of the species.The monitor shall also be responsible for ensuring the project is in compliance with conditions set forth by the USFWS in the incidental take authorization for LA2NLS914-14 pursuant to the MSHCP. BIO-10 PriQrto the construction of Phase II.the City shall pay the Riverside CQnaervation A thority. in e amount of ($14,629 per acre) for a 2.2-acre portion of 40-acre parcel, known as the Geller property.The property is identified as Geller#3 (APN B -180-001). is located in a undeveloped reach of the Temecula Creek Iloodplain. b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans,policies,or regulations,or by the California Department of Fish and Game or the U.S. Fish and Wildlife Service? No Impact.No riparian habitat or other sensitive natural communities have been identified on the project site.' The proposed project site lies completely within the existing right-of-way. The proposed project would not result in any adverse significant effect on riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations or by CDFG and USFWS; therefore, no mitigation is required. ' General Biological Resources Assessment and MSHCP Consistency Report, LSA Associates, Inc. December 2010. Ramona Expressway Widening Project •Page 33 City of San Jacinto 3.0 Environmental Checklist c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act(including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? No Impact. There are no wetlands present on the project site.' The MSHCP does not designate any survey areas or potential concern for protected wetlands,or vernal pools in the project area. No surveys or mitigation beyond participation in the MSHCP is required. d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native or resident migratory wildlife corridors,or impeded the use of native wildlife nursery sites? Less Than Significant Impact. The northern and southern segments of the proposed project are surrounded by agriculture and vacant lands. The project does not intersect any functional wildlife corridors not does it contain any nursery sites.Areas that lack residential,or commercial and other urban uses are still subject to wildlife movement and seed dispersal across Ramona Expressway. But there is no functional habitat or temporary shelter for wildlife to use. The proposed project is adjacent to an existing MSHCP Conservation Area(San Jacinto River).This is an important wildlife movement corridor/linkage and means of dispersal for plants,organic matter,sediment, and seasonal water source. It also provides a habitat for San Bernardino kangaroo rat. The proposed project will not affect this wildlife corridor because there will be no work in the river itself. The project widening will occur within adjacent existing right-of-way. e) Conflict with any local policies or ordinances protecting biological resources,such as a tree preservation policy or ordinance? No Impact.There are no specific local policies or ordinancesz protecting biological resources in addition to MSHCP. Therefore, the proposed project does not conflict with any local policies or ordinances protecting biological resources(e.g.,tree preservation policy or ordinance). No impacts associated with this issue would occur and no mitigation is required. f) Conflict with the provisions of an adopted habitat conservation plan, natural community conservation plan, or other approved local, regional, or state habitat conservation plan? Less than Significant Impact.The MSHCP and the Stephen's Kangaroo Rat Habitat Conservation Plan (SKR HCP) are the principal habitat conservation plans in western Riverside County. The project is subject to the provisions within both conservation plans refer to Checklist Question response IV(a). In addition the project's indirect effects to the existing MSHCP Conserved Lands(San Jacinto River)will b mitigated through compliance with MSHCP Section 6.1.4 Guidelines pertaining to the UrbanMildland. InterfaceSection 7 5 3• Construction Guidelines and Appendix C• Best Management Practices Within the Criteria Cells, the project will minimize any removal of veoetation remaining within the right-of-way at is outside the actual construction site and will avoid using grass-covered land for staging or parking at is outside of the right-of-way and within the proposed Conservation Area, Indirect Impacts. The project will comply with all guidelines presented in MSHCP Section 6.1.4. Guidelines Pertainino to Urban/Wildlands Interface.

CULTURAL RESOURCES a and b) Cause a substantial adverse change in the significance of a historical resource as defined in§ 15064.5? Cause a substantial adverse change in the significance of an archaeological resource pursuant to§ 15064.5? Less than Significant Impact With Mitigation Incorporated.As identified in the City's General Plan EIR,' the City has identified numerous historic and archaeological resources in the vicinity of the proposed project alignment.A Cultural Resources Assessment2 was prepared to identify and determine any historical and archaeological resources that may be present within the project limits. The Cultural Resources Assessment consisted of archival research conducted on October 5,2010,and field surveys conducted on October 14 and 15, 2010. As detailed in the Cultural Resources Assessment, no resources have been recorded within the project boundaries. However, two historic houses immediately adjacent to the project boundaries have been recorded. Based on the 43 previously conducted cultural resources studies,61 historical resources and 3 prehistoric/cultural value resources have been identified within a one-mile radius of the project's boundaries. None of these resources is located within the project boundaries.No cultural resources were identified within the project boundaries by the archival research conducted on October 5, 2010, and during field surveys conducted on October 14 and 15, 2010. While no cultural resources were identified within the project boundaries during research and field surveys,construction activity(particularly grading and soil excavation)could potentially adversely affect unknown subsurface historical and/or archaeological resources. Implementation of Mitigation Measures CUL-01 and CUL-02 would ensure that impacts to unknown subsurface historic and/or archaeological resources are reduced to a less than significant level.

If significant resources are found,then a mitigation olan 5hall be developed, in a ordan - with Section 21083.2 of CEQA and Section 1 064 5 of th QA Guidelines to ensure anv impact to discovered cultural resources is less than significant. Mitigation shall in I d photographs recordation collection and archival of collected materials, In the event that significant cultural resources are encount r d that cannot be mitigat d avoidance shall b c) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Less Than Significant Impact With Mitigation Incorporated.As identified in the City's General Plan EIR, the Division of Geological Sciences of the San Bernardino County Museum (SBCM) completed a literature review and records search of the City's General Plan area. The results of the search indicate that no previously known paleontological resource localities are recorded by the SBCM within the City's Planning Area or within a one-mile radius of the City's Planning Area. Surface exposures of Holocene alluvial valley deposits, which make up most of the City's Planning Area, have low potential to contain significant non-renewable paleontological resources and are considered to exhibit low paleontological sensitivity. However,these young alluvial sediments overlie older Pleistocene sediments present in the subsurface,which have a high potential to contain significant non-renewable paleontological resources and exhibit high paleontological sensitivity.Construction activity(particularly grading and soil excavation) is planned to be 30 inches deep including sub grade compaction. It is unlikely to affect unknown paleontological resources. If there is a potentially adverse affect to unknown subsurface paleontological resources, implementation of Mitigation Measure CUL-03 and CUL-4 would ensure that impacts to unknown subsurface paleontological resources are reduced to a less than significant level. Phases 1 and 2 CUL-03 In the event a paleontological resource is uncovered during the course of project construction, ground-disturbing activities in the vicinity of the find shall be redirected until the nature and extent of the find can be evaluated by a qualified paleontologist as determined by the City and Mitigation Measure CUL-04 shall apply. If no paleontological resource is uncovered during the course of project construction, Mitigation Measure CUL-04 will not be required. CUL-04 If paleontological resources are unearthed or discovered during the course of project construction, the following recovery processes shall apply: • Upon encountering a large deposit of bone, salvage of all bone in the area shall be conducted with additional field staff and in accordance with modern paleontological techniques. • All fossils collected during the project shall be prepared to a reasonable point of identification. Excess sediment or matrix shall be removed from the specimens to reduce the bulk and cost of storage. Itemized catalogs of all material collected and identified shall be provided to a City-identified museum repository along with the specimens. • A report documenting the results of the monitoring and salvage activities and the significance of the fossils shall be prepared and submitted to the City. Ramona Expressway Widening Project .Page 38 City of San Jacinto 3.0 Environmental Checklist • All fossils collected during this work, along with the itemized inventory of these specimens, shall be deposited in a City-identified museum repository for permanent curation and storage. d) Disturb any human remains, including those interred outside of formal cemeteries? Less Than Significant Impact. No evidence is in place to suggest the project site has been used for human burials. The California Health and Safety Code states that if human remains are discovered on site, no further disturbance shall occur until the Riverside County Coroner has made a determination of origin and disposition.' Disposition of the human remains shall occur in the manner provided in§5097.98 of the Public Resources Code.Mitigation Measure CUL-5 will ensure that State regulations are adhered to and impacts associated with the discovery of human remains would be less than significant with implementation of existing regulations and mitigation. Phases 1 and 2 CUL-05 If human remains are encountered on the project site,the Riverside County Coroner's Office MUST be enacted within 24 hours of the find and all work halted until a clearance is given by that office and any other involved agencies. If it is determined that the remains might be those of a Native American, the Native American Heritage Commission (NAHC) and the Soboba Band of Luiseno Indians shall be notified and appropriate measures provided by State law shall be implemented. VI. GEOLOGYAND SOILS a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: (i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidences of known fault? (Refer to Division of Mines and Geological Special Publication 42.) Less Than Significant Impact. Fault rupture is the most easily avoided seismic hazard. The Alquist- Priolo Earthquake Fault Zoning Act (Act) mitigates fault rupture hazards by prohibiting the location of structures for human occupancy across the trace of an active fault.The Act requires the State Geologist to delineate"Earthquake Fault Zones" along faults that are"sufficiently active"and "well defined."The boundary of an "Earthquake Fault Zone" is generally 500 feet from major active faults and from 200 to 300 feet from well defined minor faults. The mapping of active faults has been completed by the State Geologist.These maps are distributed to all affected cities, counties, and State agencies for their use in developing planning policies and controlling renovation or new construction. City of San Jacinto and its region has many seismic active faults of which two significant active faults are the Claremont fault also known as San Jacinto fault and Casa Loma fault. The Claremont fault (San Jacinto fault) is north of San Jacinto River and Casa Loma fault extends from the east side of the Lakeview Mountains to the northeast and southwest sides of Park Hill. Division 7, Dead Bodies;Chapter 2, General Provisions,§7050.5,California Health and Safety Code. Ramona Expressway Widening Project •Page 39 City of San Jacinto 3.0 Environmental Checklist The proposed project site is not identified as being within an Al,quist-Priolo Earthquake Fault Zone' and the closest approximate location of San Jacinto fault to the proposed project is approximately 1,500 feet. No fault rupture impact would result from the implementation of this project and no mitigation is required. ii) Strong seismic ground shaking? Less Than Significant Impact.Like all of Southern California,the project site has and will continue to be subject to ground shaking generated from activity on local and regional faults.The proposed project is the construction of additional lanes; however, no habitable structures are proposed. The project site would likely be a relatively low-risk location during a moderate to large earthquakes.The design of the proposed project would include seismic design parameters that are typical of roadways in California that would reduce the potential for seismic shaking-related impacts to a less than significant level. ifi) Seismic-related ground failure, including liquefaction? Less Than Significant Impact.Liquefaction occurs when loose, unconsolidated,water-laden soils are subject to shaking, causing the soils to lose cohesion as a result of seismic activities. Major portions of the City have the potential for damage due to liquefaction, particularly in the floodways adjacent to and downstream of the San Jacinto River and in the valley floor where the groundwater is less than 30 feet deep. The proposed project does not involve building structures such as bridges; but only widening of the existing expressway. Further as per the City's General Plan,developments involving grading in areas of potential liquefaction and other geological hazardous conditions, surveys of geotechnical and geologic conditions performed under direction of state licensed geologist, geotechnical engineer, and/or civil engineer are required. The proposed project will be required to take into account such review. With incorporation of appropriate design measures in the proposed project, there would be a less than significant impact related to this issue and no mitigation is required. iv) Landslides? Less Than Significant Impact. The proposed project is located along San Jacinto River which flows along San Jacinto Mountains. As per the City's General Plan, the San Jacinto Mountains foothills and San Timoteo badlands are geologically complex that are composed of sedimentary, granitic and metamorphic rock types and is subject to landslides and debris flows, particularly the easterly mountainous areas of the City. The risk of debris flow hazard is moderate to high near the easterly mountains areas. The proposed project is located along San Jacinto River on an already developed expresswayand within the existing right-of-way. Ramona Expressway is separated from the easterly mountain areas by San Jacinto River. Therefore, the roadway itself is not subject to landslides and impacts associated with landslides are anticipated to be less than significant and no mitigation measures are required. b) Result in substantial soil erosion or the loss of topsoil? Less Than Significant Impact.Soils are classified by the United States Natural Resource Conservation Service into four hydrologic soils groups based on the soil's runoff potential. "Hydrologic soil group" is a term that represents a group of soils having similar runoff potential under similar storm and cover conditions. Soil properties that influence runoff potential are those that influence the minimum rate of infiltration for bare soil after prolonged wetting.The project site contains three different categories of soils: saline-alkali,heavy clay,and vernal pool soils.The saline-alkali category consists of soils classified bythe ' Figure PS-1:Geologic and Seismic Hazards,Safety Element,City of San Jacinto General Plan,City of San Jacinto,January 2006. Ramona Expressway Widening Project •Page 40 City of San Jacinto 3.0 Environmental Checklist Natural Resources Conservation Service(NRCS) as saline-alkali(NRCS mapping units:Chino silt loam [Cf], Dello[DpB], Domino [Dt, Dv], Grangerville [GpB, GsB, GuB, GvB, GxA], Traver[fr2,Ts], Willows [Wa, Wb, Wd, Wg, and Wm]) or strongly saline-alkali (NRCS mapping units: Chino [Cg], Domino[Dw], Traver[Tt2],Willow[Wc,Wh,and Wn]).The heavy clay category consists of soils classified bythe NRCS as clays(except alkali clays,which were included in the saline-alkali category).The heavy clay category includes NRCS mapping units Auld (AaD, AaE2, AaF, AbF, AuC, AuD, AyF), Bonsanko (BfC, BfD), Porterville (PoC, PrD, PsC, PtB, PvD2) and Willows (Wf). The category of other soils potentially supporting vernal pools (i.e., soils that are known to support vernal pools not already included in the saline-alkali and heavy clays categories) includes NRCS mapping units Las Posas (LaC, LaC2) and Wyman (WyC2).' These soils have a low runoff potential and high infiltration rate when thoroughly wetted.Therefore,these soils are considered to have a low runoff or low erosion potential.Although the project site soils have a low runoff or erosion potential,the proposed project would require the excavation and movement of on-site soils, which could result in runoff or erosion issues. However, construction projects resulting in the disturbance of 1.0 acre or more are required to obtain a National Pollutant Discharge Elimination System (NPDES) permit issued by the Regional Water Quality Control Board (RWQCB).The project's construction contractor would be required to prepare a Storm Water Pollution Prevention Plan (SWPPP) that identifies Best Management Practices (BMPs) to limit the soil erosion during project construction. Adherence during construction to provisions of the NPDES permit and applicable BMPs contained in the SWPPP would ensure that potential impacts related to this issue are less than significant. No mitigation is required. c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on-site or off-site landslides, lateral spreading, subsidence, liquefaction, or collapse? Less Than Significant Impact. Subsidence is the sudden sinking or gradual downward settling of the earth's surface with little or no horizontal motion. Subsidence is caused by a variety of activities, which include (but is not limited to)withdrawal of groundwater, pumping of oil and gas from underground, the collapse of underground mines,liquefaction,and hydro-compaction.The project does not include the on- site removal of groundwater.Minor ground subsidence is expected to occur in the soils below the zone of removal due to settlement and machinery working.The actual amount of subsidence is expected to be variable and would be dependent on the type of machinery used, repetitions of use,and dynamic effects, all of which are difficult to precisely assess. Adherence to City and engineering requirements and standards would reduce potential impacts associated with this issue to a less than significant level and no mitigation is required. d) Be located on expansive soil,as defined in Table 18-1-B of the Uniform Building Code(1994), creating substantial risks to life or property? Less Than Significant Impact. Expansive soils generally have a significant amount of clay particles which can give up water (shrink) or take on water (swell). The change in volume exerts stress on buildings and other loads placed on these soils. The extent of shrink/swell is influenced by the amount and kind of clay in the soil. The occurrence of these soils is often associated with geologic units having marginal stability. The distribution of expansive soils can be widely dispersed and they can occur in hillside areas as well as low-lying alluvial basins. The soils occurring on the project site are not considered expansive soils as they do not contain significant amounts of clay. As soils covering the proposed project site are anticipated to have a low shrink-swell potential and development of-the proposed project site will be required to adhere to adopted ' General Biological Resources Assessment and MSHCP Consistency Report, LSA Associates,Inc. December 2010. Ramona Expressway Widening Project •Page 41 City of San Jacinto 3.0 Environmental Checklist design and engineering standards, impacts associated with this issue are considered less than significant. No mitigation is required. e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are notavailable for the disposal of wastewater? No Impact. The proposed project is a roadway improvement project that does not have a septic or alternative waste disposal system component;therefore,alternative wastewater disposal systems would not be utilized, no impact related to this issue would occur, and no mitigation is required. VII. GREENHOUSE GAS EMISSIONS a) Generate greenhouse gas emission, either directly or indirectly, that may have a significant impact on the environment? Less Than Significant Impact.Construction equipment and vehicles would generate greenhouse gas emissions from exhaust emissions. Construction activity is temporary in nature and would cease upon completion of the widening project. As concluded in the Air Quality Impact Study' conducted for this project,with implementation of mitigation measures short-term and long-term emissions that would result from the proposed project would not exceed SCAQMD thresholds.This amount of air pollution emissions are not considered significant on a cumulative basis,which is the focus of all analyses of greenhouse gas emissions since the emissions are considered to have only a cumulative effect when combined with greenhouse gas emissions from all other local, regional, state, national, and international sources. Therefore, a less than significant impact would occur and no mitigation is required. b) Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing greenhouse gases? No Impact. The City of San Jacinto and County of Riverside currently do not have an adopted plan, policy, or regulation for the purpose of reducing greenhouse gases.The proposed project is a roadway widening project that is consistent with the Circulation Element of the City's General Plan.Although there are no adopted plans,policies,or regulations for the purposes of reducing greenhouse gases applicable to the project, the project is consistent with the City's General Plan and would remain compatible with long-term development goals of the City. In the absence of an applicable plan, policy, or regulation adopted for the purpose of reducing greenhouse gases, no conflict would occur. Therefore, no impact would occur and no mitigation is required. V1I1. HAZARDS AND HAZARDOUS MATERIALS a) Create a significant hazard to the public or the environment through routine transport,use,or disposal of hazardous materials? Less Than Significant With Mitigation Incorporated. During the construction of the additional lanes, there would be a nominal quantity of various hazardous materials and fluids on or near the area consisting of fuels, lubricants,and other materials typically associated with construction activities.There is also a small potential for other heavy metals such as chromium to be present within the yellow thermoplastic paint markings on the pavement within the project area.Mitigation Measure HAZ-01 has been identified as reducing impacts related to this issue. ' Ramona Expressway(SR-79)Expansion Air Quality Impact Study,RK Engineering Group,Inc.,April 2,2009. Ramona Expressway Widening Project •Page 42 City of Sara Jacinto 3.0 Environmental Checklist The transport, use, and storage of hazardous materials during the construction of the site will be conducted in accordance with all applicable state and federal laws. Compliance with all applicable laws and regulations and adherence to Mitigation Measures HAZ-01 through HAZ-03 would reduce the potential impact associated with the routine transport,use,storage,or disposal of hazardous materials to a less than significant level. Phases 1 and 2 HAZ-01 Prior to the removal of the existing pavement within the project site containing yellow thermoplastic markings shall be tested for lead-based paint. If markings are found to contain lead-based paint,then Mitigation Measures HAZ-02 and HAZ-03 shall apply.Conversely,if markings are found to contain no lead-based paint,then Mitigation Measures HAZ-02 and HAZ-03 would not apply. HAZ-02 Priorto any demolition activity, materials containing lead-based paint shall be removed from the site and hauled to a licensed receiving facility and disposed of by a transportation company certified to handle materials containing lead-based paint. HAZ-03 Following completion of the lead-based paint removal, a report documenting the abatement procedures used, the volume of lead-based paint removed, and where the materials were deposited,along with transportation/disposal manifests ordump tickets,shall be submitted to the City. b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? Less Than Significant Impact.Because the proposed project is a transportation improvement project, the range of activities that would occur on the project site during the operational phase would not allow for the use, storage, disposal or transport of large volumes of toxic, flammable, explosive, or otherwise hazardous materials that could cause serious environmental damage in the event of an accident. All activity involving hazardous substances during the operation of the proposed project would be conducted in accordance with applicable local, state, and federal safety standards and would result in a less than significant impact. Ramona Expressway is designated limited-access conventional highway (Sanderson to San Jacinto Avenue) and Urban Arterial (San Jacinto to Main Street/Lake Park Drive) in the City's General Plan.' Based on the Department of Transportation Federal Motor Carrier Safety Administration, Ramona Expressway is not considered to be a restricted, designated, or preferred road or highway route for transporting radioactive and non-radioactive hazardous materials. Although Ramona Expressway is not identified as a preferred road for transporting non-radioactive hazardous, some transportation of hazardous materials along this route is anticipated. However, the transport of hazardous materials would be limited and consist of common household hazardous materials such as solvents, landscaping pesticides, paint,and lubricants typically found and sold in retail facilities. In the unlikely event that the release of these hazardous materials into the environment occurs, the containment would be easily facilitated due to the small quantities of common household hazardous materials that would be transported. Because the proposed project would improve roadway conditions on Ramona Expressway and any spills that may occur will be subject to local,state, and federal guidelines 1 Circulation Element,City of San Jacinto General Plan,Table C-1-Overview of Street Classification. 2 Transportation of Hazardous Materials:Designated,Preferred,and Restricted Routes,Federal Register Volume 65,No.233, Federal Motor Carrier Safety Administration,Department of Transportation,December 2000. Ramona Expressway Widening Project •Page 43 City of San Jacinto 3.0 Environmental Checklist for the clean up of hazardous materials spills, impacts related to this issue would be reduced to a less than significant level and no mitigation would be required. c) Emit hazardous emissions or handle hazardous or acutely hazardous materials,substances, or waste within one-quarter mile of an existing or proposed school? No Impact The nearest schools to the project site are North Mountain Middle School adjacent to Antonio Estudillo Elementary and Mountain View Alternative High adjacent to De Anza Elementary, all located approximately 0.50 to 0.65 mile west of the project site. Other schools in the proximity of the project site include Record Elementary, San Jacinto Elementary, Monte Vista Middle, North Mountain Middle and San Jacinto High all are located within 1 mile of the proposed project. The proposed project site is not located within 0.25 mile of an existing or proposed school;'therefore,no impact associated with this issue is anticipated to occur and no mitigation is required. d) Be located on site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and,as a result, would it create a significant hazard to the public or the environment? No Impact. The project site in not included on a list of hazardous materials sites as identified by Government Code Section 65962.5 (Cortese List). There are no Leaking Underground Storage Tank (LUST) sites identified within a search radius of/a mile from the proposed project site. Therefore, no impacts associated with this issue would occur and no mitigation is required. e) For a project located within an airport land use plan or where such a plan has not been adopted within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? No Impact.The closest airport to San Jacinto is the Hemet-Ryan airport located southwest to the project. No private airports or heliports2 are located within or in close proximity to the City. The Hemet-Ryan Airport is located approximately 7 miles southwest of the project site in the City of Hemet. The airport is currently owned and operated by Riverside County Economic Development Department. Since 1957, the airport has provided the base for fire fighting operations for the California Division of Forestry(CDF) and the United States Forest Service (USFS). The proposed project is the widening of an existing roadway, which is not located within an airport land use plan or within 2 miles of a public airport or public use airport,and would not result in a safety hazard for people working and residing in the area.Therefore, no impacts related to this issue would occur and no mitigation is required. f) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? No Impact.The project is not located within the vicinity of a private airstrip or heliport(refer to Checklist Question VIII[e] response). Consequently, no impacts associated with this issue would occur and no mitigation is required. ' Telephone communication vAth Michael P.Collins,Director II of Facilities and Operations,San Jacinto Unified School District on November 23,2010. x California Airport Land Use Planning Handbook, State of California, Department of Transportation, Division of Aeronautics, January 2002. Ramona Expressway Widening Project •Page 44 City of San Jacinto 3.0 Environmental Checklist g) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? Less Than Significant Impact.The proposed project would be designed,constructed,and maintained in accordance with applicable standards associated with vehicular access, resulting in the provision of adequate vehicular access that will provide for adequate emergency access and evacuation.Construction activities that may temporarily restrict vehicular traffic would be required to implement adequate and appropriate measures to facilitate the passage of persons and vehicles through/around any required road closures.Adherence to these measures would reduce potential impacts related to this issue to a less than significant level, and no mitigation is required. h) Expose people or structures to a significant risk of loss, injury, or death involving wildland fires including where wildlands are adjacent to urbanized areas or where residents are intermixed with wildlands? No Impact. The City of San Jacinto is subject to wildland fires, especially in the hillsides. The City contracts with the Riverside County Fire Department (RCOFD) to provide fire protection services that includes fuel modification zones around existing and proposed development. The City and RCOFD review developments to ensure that the existing level of staffing and services are adequate forf ire fighting purpose. Areas surrounding the project site consist of San Jacinto River basin and some agricultural areas and some moderately urban and built areas. To some extent the San Jacinto River forms a natural barrier to the advancement of wildfires from San Jacinto Mountains. However,the risk of wildfires remains as the hillsides located in both the westernmost and easternmost portions of the City are High Fire Hazards Areas. Ramona Expressway provides an important route for evacuation in the event of a wildfire.To that end,the proposed project will add to the existing capacity of Ramona Expressway, which is a beneficial effect of the project. /X. HYDROLOGY AND WATER QUALITY a) Violate any water quality standards or waste discharge requirements? Less Than Significant Impact. Construction projects resulting in the disturbance of 1.0 acre or more require a National Pollutant Discharge Elimination System(NPDES)permit.It is anticipated that since the proposed project is a City facility, the City would file a Notice of Intent (NOI) to comply with the NPDES Construction Activity General Permit. A component of the NPDES permit is the preparation of a Storm Water Pollution Prevention Plan(SW PPP).The purpose of an SW PPP is to identify and implement Best Management Practices (BMPs) to reduce impacts to surface water from contaminated stormwater discharges.Compliance with the project-specific SW PPP would reduce impacts related to this issue to a less than significant level and no mitigation is required. b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level(e.g.,the production rate of preexisting nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? Less Than Significant Impact.The City of San Jacinto is located within the San Jacinto Groundwater Subbasin. Groundwater is found at varying depths ranging from 30 feet to several hundred feet deep.' The proposed project consists of roadway widening that would result in additional lanes in each direction ' City of San Jacinto General Plan, Public Safety Element. Ramona Expressway Widening Project .Page 45 City of San Jacinto 3.0 Environmental Checklist on the existing Ramona Expressway segments between Sanderson Avenue to Eagle Street and from Eagle Street to Main Street. Because the project is a roadway improvement project,development of the proposed project would not require any withdrawal of groundwater beneath the project site. The construction of the additional lanes would require the excavation of soil for foundation and roadbed. Because there would not be any direct withdrawal of water with the implementation of the proposed project, impacts associated with groundwater and groundwater recharge are considered less than significant and no mitigation is required. c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on site or off site? Less Than Significant Impact. The proposed project would add approximately 15.73 acres of new impervious surfaces to the project area.' However, the proposed project would not involve a change in land use with the exception of converting some vacant areas within the existing right-of-way to additional lanes. It is anticipated that because the project site would add a minimal amount of impervious surfaces, the effect of the proposed project on the velocity or volume of downstream flows would be negligible,and no substantial hydraulic changes or erosion would occur. Therefore impacts related to this issue are considered to be less than significant and no mitigation is required. d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on site or off site? Less Than Significant Impact Please refer to Checklist Question VI II(c) response. Implementation of the proposed project would not significantly alter the existing drainage pattern of the project site,resulting in a less than significant impact to drainage. e) Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff? Less Than Significant Impact.Development of the project site would result in an increase in the amount of impervious surfaces in the form of additional roadway pavement.Conditions resulting from this change could degrade existing water quality due to increased runoff volumes and velocity; reduce infiltration; increase flow frequency, duration, and peak; and result in faster time to reach peak flow. However, implementation of the proposed project would include the installation of treatment BMPs as identified in the SWPPP that would remove pollutants from runoff coming from the project site. Because treatment BMPs would be installed, impacts associated with this issue would be reduced to below a level of significance and no mitigation would be required. f) Otherwise substantially degrade water quality? Less Than Significant Impact with Mitigation Incorporated.Storm runoff from roadways can carry and be tainted by a variety of pollutants such as sediment, petroleum products, and(to a lesser extent)trace metals such as zinc, copper, lead, cadmium,and iron that may lead to the degradation of stormwater in downstream channels. Pollutant concentrations in urban runoff are extremely variable and are dependent on storm intensity, land use,elapsed time since previous storms,and the volume of runoff generated in a given area that reaches nearby receiving waters. Potential water quality impacts are variable and related to the increase in the peak runoff,type,and extent of new urban uses,and the sensitivity of the receiving water. Development of the project could result in increased peak flow and pollutant loads in the local drainage ways. ' Communication with Tri-lake Engineering,Chris Sunde,Project Manager,January 2011. Ramona Expressway Widening Project •Page 46 City of San Jacinto 3.0 Environmental Checklist During the construction period, the project would use a series of BMPs to reduce erosion and sedimentation.These measures may include the use of gravel bags,silt fences,hay bales,check dams, hydroseed,and soil binders.The construction contractorwould be required to operate and maintain these controls throughout the duration of on-site activities. In addition, the construction contractor would be required to maintain an inspection log and have the log on site in the event that review by the City or representatives of the RWQCB is required.To ensure that an NPDES permit has been obtained prior to construction activities, Mitigation Measure HYD-01 has been identified. With implementation of the erosion/sedimentation/pollution control measures required in the NPDES construction permit,short-term construction-related water quality impacts would be reduced to below a level of significance. Phases 1 and 2 HYD-01 Prior to the issuance of grading permits, the project proponent shall submit the Waste Discharge Identification Number to the City of San Jacinto as proof that the project's Notice of Intent (NOI) to be covered by the General Construction Permit has been filed with the appropriate RWQCB. Because adherence to the requirements of the NPDES permit and the SWPPP would be required by the City prior to,during,and after construction,potential negative water quality impacts would be reduced to a less than significant level. g) Place housing within a 100-year flood hazard area as mapped on a Federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazards delineation? No Impact.The project does not include a residential component; therefore, it will not place housing within a 100-year flood hazard area,as mapped on a Federal Flood Hazard Boundary or Flood Insurance Rate Map. No impact related to this issue would occur with the implementation of the proposed project and no mitigation is required. h) Place within a 100-year flood hazard area structures that would impede or redirect flood flows? Less Than Significant Impact. Based on Flood insurance Rate Map (FIRM), portions of the existing Ramona Expressway are located within 100-yearfloodplain. Ramona Expressway has been designed to withstand floodwaters. Features such as levee along portions of San Jacinto River are designed to protect the area against potential flooding. Since the proposed project is widening to an already existing roadway that is protected by levees; therefore, impacts related to this issue are considered to be less than significant and no mitigation is required. i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? Less Than Significant Impact.In the remote event of levee failure,the project site would be exposed to flood risk of the San Jacinto River. Although the project site is subject to such an event, occurrence of such an event is extremely remote as the San Jacinto River levee has been engineered and constructed to withstand the projected maximum accelerations that could be produced at the site by seismic events on known faults. As such, a seismically-induced failure of the levee is unlikely. For these reasons, potential impacts related to this issue are less than significant and no mitigation is required. j) Expose people or structures to inundation by seiche, tsunami, or mudflow? Less Than Significant Impact. A tsunami is a series of waves generated in a body of water by a pulsating or abrupt disturbance that vertically displaces water.Inundation of the proposed project's site by a tsunami is highly unlikely as the project site is approximately 54.0 miles northeast of the Pacific Ocean. Ramona Expressway Widening Project .Page 47 City of San Jacinto 3.0 Environmental Checklist Seiches are oscillations in enclosed bodies of water such as lakes, ponds, and water tanks that are caused by a number of factors;most often wind or seismic activity.There are no enclosed bodies of water within the vicinity of the project.Because the proposed project site is not located adjacent to any enclosed bodies of water, no seiche-related flooding is anticipated to occur on site. A mudflow occurs when there is fast-moving water and a great volume of sediment and debris that surges down a slope, stream, canyon, arroyo, or gulch with tremendous force. They are similar to flash floods and can occur suddenly without time for adequate warning. Mudflows can ruin substantial improvements with the force of the flow itself and the burying or erosion of improvements by mud and debris.This type of event can be caused by a combination of events which include flooding, landsliding, or earthquake. However,for a mudflow event to occur there must be fast-moving water and a great volume of sediment and debris. Without these two components, a mudslide is unlikely to occur. The project site is in an area of the City where landslide susceptibility is not identified.' However, the project site's location in a floodplain, its general proximity to major earthquake fault systems, and its location to San Jacinto River indicates that the occurrence of a mud slide coming through the area is possible. Although there is a possibility that a mud slide could come through the area, the proposed project is protected by levees associated with the San Jacinto River and would be built to withstand floodwaters, which are a significant component of a mudslide. Because the proposed project would be designed to withstand floodwaters and is protected by a levee,impacts associated with mudslides would be reduced to below a level of significance and no mitigation measures are required. X. LAND USE AND PLANNING a) Physically divide an established community? No Impact Ramona Expressway is an existing roadway within the City. The proposed project would widen the existing roadway in an area that is currently developed with commercial and residential uses, which are already divided into distinct commercial centers and neighborhoods by the existing roadway. The project site would not further divide an existing neighborhood, nor would it introduce a barrier between existing or planned land uses therefore, no impact related to this issue would occur and no mitigation is required. b) Conflict with any applicable land use plan,policy or regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? No Impact. Ramona Expressway is a designated limited access conventional highway(6-8 lanes)and partly urban arterial in the Circulation Element of City of San Jacinto's General Plan.All work proposed under the project would occur within the existing roadway right-of-way. Land uses along Ramona Expressway include adjoining roads and infrastructure, commercial shopping areas, rural residences, newly developed single-family homes, and agricultural lands. Implementation of the project does not require any amendments to City zoning designations or General Plan. There are no specific plans or other land use plans applicable to the proposed project.The proposed project would remain consistent with the General Plan; therefore, it would not conflict with an applicable land use plan. Therefore, no impact related to this issue would occur. No mitigation is required. 1 City of San Jacinto General Plan, Public Safety Element. Ramona Expressway Widening Project •Page 48 City of San Jacinto 3.0 Environmental Checklist c) Conflict with any applicable habitat conservation plan or natural community conservation plan? Less Than Significant Impact.As detailed in Checklist Response IV(a),the project site is located within and adjacent to four Cells in the Western Riverside Multiple Species Habitat Conservation Plan(MSHCP) San Jacinto Valley Area Plan. The project will not affect any areas important to the creation of the MSHCP Reserve.The project is limited to previously disturbed ordeveloped areas and the existing right- of-way.The project site is located within the MSHCP Burrowing Owl Survey Area. Suitable habitat forthe burrowing owl is present within and adjacent to the project site; therefore, focused surveys (presence/absence)forthe burrowing owl would be conducted pursuant to the MSHCP.The project site contains several trees suitable for avian nesting. If tree removal is to take place during the nesting season, generally February 1 through August 31, pre-construction nest survey(s) would be required to ensure that no active nests are on or adjacent to the project site.Additionally,the project is located within an MSHCP Mammal Survey Area. Focused surveys for San Bernardino kangaroo rat and Los Angeles pocket mouse would be conducted prior to construction. Implementation of the proposed project would be required to adhere to applicable requirements of the Western Riverside MSHCP San Jacinto Valley Area Plan. Implementation of the proposed project would not conflict with the applicable habitat conservation plan.A less than significant impact would occur and no mitigation is required beyond that required in Section IV of the Checklist. Xl. MINERAL RESOURCES a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? No Impact.Based on the City of San Jacinto General Plan,the City is not located within a known mineral resource zone designated by the State of California (Mineral Resource Zone 2 [MRZ-2]).' As per the Department of Conservation Division of Mines and Geology,areas identified as MRZ-2 are considered to have significant deposits that are likely to be present. Sand, gravel, and limestone resources are identified in the eastern portion of the City, east of San Jacinto River,also east of the proposed project. The proposed project consists of the widening of an existing roadway with addition of two lanes in each direction.Therefore,implementation of the proposed project would not significantly affect the availability of mineral resources in the project vicinity, no impact related to this issue would occur,and no mitigation is required. b) Result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan? No Impact.The proposed project site is not classified as an area of locally important mineral resource recovery. No impact related to this issue will occur and no mitigation is required. XII. NOISE a) Exposure of persons to orgeneration of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Less Than Significant With Mitigation Incorporated. Noise increases from the proposed project would be generated on a short-term and long-term basis. Short-term noise levels are associated with excavation, grading, and roadway construction. Short-term noise levels would be higher than existing ' Resource Management Element,City of San Jacinto General Plan,City of San Jacinto,January 2006. Ramona Expressway Widening Project Page 49 City of San Jacinto 3.0 Environmental Checklist ambient noise levels in the project area,but would cease upon project completion.Long-term noise levels would be associated with traffic noise on Ramona Expressway. Based on City of San Jacinto's Noise Element,' the acceptable interior noise standard for residential uses is 45 CNEL (dBA) and the acceptable exterior noise standard for residential uses is 65 CNEL(dBA).2 Based on the acoustical study prepared forthe project,3 the existing traffic noise levels do not exceed the City's exterior noise standard at all the noise-sensitive locations monitored adjacent to Ramona Expressway. The future exterior noise levels on completion of the project will change marginally by approximately-1.9 to 4.8 CNEL(dBA)(Refer to Table A).The primary reason for this marginal increase is due to the change in distance from the centerline to sensitive receptors. The increase in the width of Ramona Expressway due to addition of lanes increases the distance between centerline to the sensitive receptors. An increase in 3 dBA is audible and any noise level below 3 dBA is not audible to the human ear.The existing noise level at one of the sensitive receptors (R7) is already at 66.3 dBA CNEL and the increase at that receptor is 0.3 dBA; a marginal increase which is not perceptible. Therefore, the proposed project will not lead to a substantial increase in the roadway ambient noise levels in excess of the City's regulatory standards. Construction activities would include use of typical construction equipment such as trucks, graders, backhoes, pavers, and portable generators.These would generate peak noise levels of approximately 70-90 dBA at a distance of 50 feet from the noise source.The worst- case construction noise will range from 72.0 to 76.7 dBA Leq with a maximum level of 80 dBA LR18,,. Table A: Existing and Future Traffic Noise Levels (dBA Leq) Receptor Number Existing Approximate Wall Height Existing Future Build Change in Noise Phase 1 (State Street to Main Street) R1 7.5 feet 61.3 62.4 1.1 R2 6.0 feet 58.5 58.6 0.1 Phase 2(Sanderson Avenue to State Street) R3 6.5 feet 63.7 64.0 0.3 R4 6.5 feet 65.9 64.0 -1.9 R5 6.5 feet 59.1 63.9 4.8 R6 5.5 feet 61.0 63.8 2.8 R7 - 66.3 66.6 0.3 Source: Ramona Expressway Expansion Acoustical Study,RK Engineering Group,Inc.,March 2009, Construction activities for the proposed project will adhere to City of San Jacinto's Municipal Code 8.40.090 which regulates construction activity noise. As per the noise ordinance, the construction contractor shall limit all construction-related activities that would result in high noise levels to between the hours of 7:30 a.m. and 6:00 p.m. Monday through Friday. No construction activities shall be allowed on Sundays and public holidays.Additionally,since construction activities would generate noise in excess of City noise standards, Mitigation Measures NOS-01 through NOS-05 have been identified.Adherence to these measures in addition to compliance with City noise regulations would reduce impacts related to this impact to a less than significant level. ' Noise Element, City of San Jacinto General Plan,City of San Jacinto,January 2006. 2 Chapter 0.40 Noise Control,City of San Jacinto Municipal Code,May 2008. Ramona Expressway Expansion Acoustical Study,RK Engineering Group Inc.March 2009. Ramona Expressway Widening Project •Page SO City of San Jacinto 3.0 Environmental Checklist Phases 1 and 2 NOS-01 During construction,the contractor shall ensure all construction equipment is equipped with appropriate noise attenuating devices. The project contractor shall equip all construction equipment,fixed or mobile,with properly operating and maintained mufflers consistent with manufacturers' standards. NOS-02 Idling equipment should be turned off when not in use. NOS-03 Equipment will be maintained so that parts of vehicles and their loads are secured from rattling and banging. NOS-04 The construction contractor shall locate equipment staging in areas that will create the greatest distance between construction-related noise sources and noise-sensitive receptors during all project construction. NOS-05 If noise complaints demonstrate that a significant noise impact is affecting sensitive noise receptors due to construction activities(noise levels measured at the receptor location),the City may require the contractor to apply further measures to reduce noise impact by implementing a noise and vibration control plan which is indicated as follows: a. Pursuant to the City's request, portable sound level meters would be utilized to determine and verify the noise impact from the construction equipment to the sensitive receptor location. b) Exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels? Less Than Significant Impact. Vibration refers to groundborne noise and perceptible motion. Typical sources of groundbome vibration are construction activities(e.g.,blasting,pile driving,and operating heavy- duty earthmoving equipment), steel-wheeled trains, and occasional traffic on rough roads. Groundborne vibration is almost exclusively a concern inside buildings and is rarely perceived as a problem outdoors, where the motion may be discernable but without the accompanying effects (e.g., shaking of a building). Building damage is not a factor for normal projects,with the occasional exception of blasting and pile driving during construction. Problems with groundborne vibration and noise are usually localized to areas within about 100 feet from the vibration source, although there are examples of groundborne vibration causing interference out to distances greater than 200 feet.The level of vibration is not excessive or permanent,nor would it cause any damage to the buildings. Therefore, impacts from construction-related groundborne vibration construction would be less than significant and no mitigation is required. c) A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? Less Than Significant Impact. Long-term noise impacts associated with the proposed project will not result in substantial permanent increase in ambient noise levels in the project's vicinity. The predicted future Build CNEL at the seven identified sensitive receptors range from approximately 58.6 to 66.6 dBA CNEL, exceeding the City's exterior noise standards at only one of the representative receiver location. R7 is the only representative receptor where the noise level exceeds the City's standard of exterior noise levels of 65 dBA CNEL. Long-term traffic noise impacts were evaluated using the Caltrans Technical Noise Supplement procedures. Previously referenced Table A identifies existing and future traffic noise levels at each receptor location.As identified in Table A, receptor R7 in Phase 2 would be exposed or would continue to be exposed to noise levels that approach or exceed the City's exterior noise threshold of 65 dBA, however, the increase is 0.3 dBA which is not perceptible to the human ear and is not considered a significant increase. R7 noise measurement was recorded near the front yard of an existing residential Ramona Expressway Widening Project •Page 51 City of San Jacinto 3.0 Environmental Checklist units located along Ramona Expressway. Therefore, no mitigation measures are proposed for this minimal increase in noise. The traffic noise levels are not expected to exceed the City's exterior noise threshold of 65 dBA CNEL for sensitive receivers R1 through R6. It is anticipated that the existing walls along the project site corridor are of sufficient height to buffer residences to meet the City's exterior noise standard, based on the existing volumes. d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? Less Than Significant With Mitigation Incorporated.Temporary or periodic increases in ambient noise levels would occur during the construction of the proposed project.Construction of the proposed project is expected to require the use of earthmovers, bulldozers, water trucks, and pickup trucks.The maximum composite noise level would be 70 to 90 dBA Lmax at a distance of 50 feet from an active construction site. The closest sensitive receptors are residences located along Ramona Expressway. These sensitive receptors may be subject to short-term noise reaching up to 80 dBA Lmax generated by construction activities occurring on the project site. Noise generated during the construction phase is temporary and would cease once construction has been completed. Because construction activities would generate noise in excess of City noise standards, Mitigation Measures NOS-01 through NOS-05 have been identified. Adherence to these measures in addition to compliance with City noise regulations would reduce impacts associated with this issue to a less than significant level. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? No Impact. Refer to Checklist Response IX (e). Additionally,the proposed project is a roadway project that would not have people residing or working on the project site for long periods of time. Taking into consideration these factors, no impacts related to this issue would occur and no mitigation is required. f) Fora project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? No Impact.The proposed project site is not located within the vicinity of a private airstrip;therefore, no impact associated with this issue would occur and mitigation is not required. Xll1. POPULATION AND HOUSING a) Induce substantial population growth in an area,either directly(e.g.,by proposing new homes and businesses)or indirectly(e.g., through extension of roads or other infrastructure)? No Impact.The proposed project would result in the widening of an existing roadway within the City's right of way. The purpose of the proposed project is expansion of the existing Ramona Expressway to accommodate traffic and improve public safety consistent with the City's General Plan Circulation Element. Therefore, it will not induce growth unlike the development of a residential, commercial, or industrial use. The extent to which new jobs created by a project are filled by existing residents is a factor that tends to reduce the growth inducing effect of a project. The construction of the proposed project would create short-term construction jobs; however,these short-term positions are anticipated to be filled by workers who,for the most part, reside in the project area.Therefore,construction of the proposed project will not generate a permanent increase in population within the project area. Infrastructure, including roads, Ramona Expressway Widening Project •Page 52 City of San Jacinto 3.0 Environmental Checklist sewers,water,and electricity, already exists around the project site.Because the proposed project would remediate existing deficiencies in current roadway configurations, the widening of the Ramona Expressway would not induce indirect growth above that which currently exists or is planned fro in the City's General Plan. Therefore, no impacts associated with this issue would occur and no mitigation is required. b) Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? No Impact.The proposed project site consists of the construction and operation of associated roadway improvements with no residential structures located within the project limits, which is the City's existing right of way for Ramona Expressway. Because there are no residential structures within the project limits, no displacement of housing or residents would occur and construction of replacement housing is not required. No impact associated with this issue would occur and no mitigation is necessary. c) Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? No Impact. The proposed project would result in the construction of additional lanes to an existing roadway within existing right of way and would not result in the displacement of people. Because the proposed project would not result in the displacement of people,the construction of replacement housing is not required. Therefore, no impacts associated with this impact would occur and no mitigation is required. XIV. PUBLIC SERVICES Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities,need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios,response times or other performance objectives for any of the public services: Response time is the period of time between when a call is received by a dispatcher and the arrival of a fire protection unit or a police patrol car. The response time varies depending upon the nature of the call. Typical calls are prioritized based upon the urgency of the incident.The average emergency call response time for a fire or police unit (Priority 1 [life-threatening] calls) is less than five minutes. Other response times will vary depending on the level of priority in conjunction with the availability of a fire or police unit. a) Fire Protection? No Impact. Fire protection services are currently provided to the City through contract services with the Riverside County Fire Department.The Riverside County Fire Department maintains a fire station at 160 W.6th Street in the Cityand at 132 S.San Jacinto Avenue.The proposed project would result in roadway widening and roadway improvements that would not require additional fire protection services. Ramona Expressway is an existing roadway in the City with existing adjacent land uses throughout the alignment. Fire protection services are already provided to the project area. Because the proposed project would not require the provision of new fire protection services as they already exist, no impacts would occur with respect to the provision of fire protection services and no mitigation is required. Ramona Expressway Widening Project •Page 53 City of San Jacinto 3.0 Environmental Checklist b) Police Protection? No Impact Police protection services are currently provided to the City through contract services with the Riverside County Sheriff's Department. The Riverside County Sheriff's Department maintains a police station at 160 W. 6'h Street in the City. The proposed project would result in roadway widening and roadway improvements that would not require additional police protection services.Ramona Expressway is an existing roadway in the City with existing adjacent land uses throughout the alignment. Police protection services are already provided to the project area. Because the proposed project would not require the provision of new police protection services as theyalready exist, no impacts would occur with respect to the provision of police protection services and no mitigation is required. c) Schools? No Impact. The proposed project is a roadway improvement project and would not include building residential units that would house school-age children.The implementation of the proposed project would not affect schools in the nearby area as the project is a roadway improvement and would not generate additional students.The proposed project would not reduce the level of service at school facilities. It is anticipated that construction activities and vehicles would not hinder the passage of school buses on Ramona Expressway as most construction vehicles would be at the project site before school commences.Therefore,no impacts associated with this issue would occur and no mitigation is required. d) Parks? No Impact.The proposed project does not include a residential component and would not contribute to a direct increase in population. As there is no direct increase in population resulting from the proposed project,no new demand on existing park facilities would occur. In addition the roadway widening will take place within existing right-of-way and will not impact existing or future planned parks. Therefore, no impacts associated with this issue would occur and no mitigation is necessary. e) Other Public Facilities? No Impact.The proposed project is a roadway improvement project and,as a result,would not cause an increase in population resulting in a significant impact on other public facilities such as libraries and hospital services. The proposed project does not include a residential component and would not contribute to a direct increase in population.As there is no direct increase in population resulting from the proposed project, no new significant demand on library or medical facilities would occur. In the absence of a significant impact, the construction of new facilities that would result in a significant environmental impact would not occur and no mitigation is required. XV. RECREATION a) Increase the use of existing neighborhood or regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? No Impact.The proposed project is a roadway improvement project that would improve public safety on the roadway and improve mobility within the City. No residential component is proposed as part of the project;therefore, no direct increase in population would occur.The proposed project would not create additional demand on existing neighborhood or regional parks or on other recreational facilities. Because the proposed project would not create an additional demand on existing recreational facilities, it would not cause substantial physical deterioration on existing facilities.Therefore, no impacts would occur and no mitigation is required. Ramona Expressway Widening Project •Page 54 City of San Jacinto 3.0 Environmental Checklist b) Include recreational facilities or require the construction or expansion of recreational facilities that might have an adverse physical affect on the environment? No Impact. The proposed project is the widening of Ramona Expressway. This roadway segment is designated as a Limited Access Conventional Highway with a Class I bikeway. The proposed project does not include the construction and operation of new or expanded recreational facilities. Because the project would not result in an adverse physical effect, impacts related to this issue are less than significant; therefore, no mitigation is required. XVI. TRANSPORTATION AND TRAFFIC a) Conflict with an applicable plan, ordinance or policy establishing measures of effectiveness for the performance of the circulation system,taking into account all modes of transportation including mass transit and non-motorized travel and relevant components of the circulation system including but not limited to intersections,streets,highways and freeways,pedestrian and bicycle paths, and mass transit? b) Conflict with an applicable congestion management program,including not limited to a level of service standards and travel demand measures, or other standards established by the county congestion management agency for designated roads or highways? Less Than Significant Impact. Short-Term Impacts.The project itself does not generate traffic per se but rather accommodates traffic from surrounding land uses, as outlined in the City's General Plan Land Use and Circulation Elements (CSJ 2006a). The project would add some additional traffic along area roadways that connect with Ramona Expressway during the construction phase. However, this traffic would be minimal and temporary in nature, and would cease upon completion of project construction. Long-Term Impacts.This project proposes to widen Ramona Expressway from 4 to 6 lanes between Sanderson Avenue and Eagle Road (Phase 1),and widen it from 2 to 4 lanes from Eagle Road to Main Street/Lake Park Drive (Phase 2). Figure C-2 of the City's Circulation Element shows the Phase 1 segment is planned to be eventually a"Limited Access Conventional Highway"with 6 to 8 travel lanes (184-foot Right-Of-Way or ROW), and the Phase 2 segment is proposed to eventually be an "Urban Arterial" with 6 travel lanes (146-foot ROW). The improvements planned as part of this project are consistent with the roadway system planned in the City's Circulation Element(Figure C-2, CSJ 2006a) and the network analyzed in the Environmental Impact Report(EIR)prepared for the General Plan(CSJ 2006b)including the Circulation Element.The General Plan EIR concluded that a significant traffic impact on a particular roadway segment or at a particular intersection would occur if the Level of Service (LOS) of that roadway segment or intersection exceeded LOS D (DEIR page 5.13-11, CSJ 2006b). The General Plan concluded that long-term traffic on Ramona Expressway west of Warren Road (west and outside of the proposed project limits)would be significant at build out(year2050 and beyond),even with the augmented improvements indicated in the General Plan, because a number of roadway segments and intersections would exceed LOS D. The EIR also concluded that traffic impacts along Ramona Expressway within the proposed project limits (i.e., Sanderson to Main Street) would be less than significant with implementation of planned improvements(DEIR page 5.13-27,CSJ 2006b).The EIR concluded that the planned improvements to the Ramona Expressway would be needed for build out traffic with or without the other planned roadways and improvements (e.g., Highway 79 and Mid-County Parkway).The proposed project represents the full improvements currently planned for this segment of Ramona Expressway in terms of travel lanes.For these reasons, long-term traffic impacts related to this project will be less than significant, and no mitigation is required. Ramona Expressway Widening Project •Page 55 City of San Jacinto 3.0 Environmental Checklist Other Impacts.The following section (f) evaluates potential impacts of the proposed project relative to mass transit, bicycle lanes, but the project is not expected to cause significant impacts relative to these issues. c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? No Impact.The proposed project is a series of roadway improvements and would not cause any changes to airtraffic volumes or air traffic patterns.Therefore, no impact related to this issue would occur and no mitigation is required. d) Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections)or incompatible uses(e.g., farm equipment)? Less Than Significant Impact.The construction of the proposed improvements to Ramona Expressway would alleviate potential circulation problems and/or hazards with the existing roadway by widening the two segments, including drainage improvements. The design of the proposed project does not include any sharp curves or dangerous intersections. Therefore, the project would not create a substantial increase in hazards due to a design feature and would in fact be a beneficial impact in this regard. Impacts associated with this issue are less than significant and no mitigation is required. e) Result in inadequate emergency access? Less Than Significant Impact.The proposed project would be required to be designed, constructed, and maintained to provide for adequate emergency access and evacuation.Construction activities,which may temporarily restrict vehicular traffic, would be required to implement adequate and appropriate measures to facilitate the passage of persons and vehicles through/around any required road closures. The proposed project design would be submitted to and approved by the City's Fire and Police Departments prior the issuance of construction permits. A less than significant impact related to this issue would occur and no mitigation is required. f) Conflict with adopted policies,plans,or programs supporting alternative transportation(e.g., bus turnouts, bicycle lanes,sidewalks, etc.)? Less Than Significant Impact.The proposed project would result in widening Ramona Expressway from Sanderson to Main Street, a distance of approximately 5 miles. The planned improvements include sidewalks on both sides of the street which would support alternative transportation such as walking. Additionally, the roadway west of Sanderson (just west and out of the project area) is planned to eventually accommodate a multi-function trail (pedestrian, bicycle, and equestrian use), and even the placement of commuter rail service within the median of the expressway west of Sanderson has been discussed (RCTC 2007).The widened roadway will also accommodate regular turnouts for bus service. Because the proposed project would enhance existing infrastructure that supports alternative transportation options,and because the proposed project would comply with adopted policies, plans, or programs supporting alternative transportation,no impacts associated with these issues are anticipated to occur, and no mitigation is required. XV11. UTILITIES AND SERVICE SYSTEMS a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? No Impact.The proposed project would not generate wastewater as the proposed project is a roadway improvement project. Because the proposed project would not generate wastewater, the wastewater Ramona Expressway Widening Project •Page 56 City of San Jacinto 3.0 Environmental Checklist treatment requirements of the Santa Ana Regional Water Quality Control Board(RWQCB)would not be exceeded. Therefore, no impact would occur and no mitigation required. b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? No Impact. Implementation of the proposed project would not require water or wastewater services as the project is a roadway improvement project that does not require water for roadway or median landscaping. Because the proposed project would not require water or wastewater services, the construction of additional water or wastewater treatment facilities or the expansion of existing facilities to serve the project would not occur.Therefore, no impacts associated with this issue would occur and no mitigation is required. c) Require or result in the construction of new stormwater drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? Less Than Significant Impact. Development of the proposed project will result in an increase in the amount of impermeable surfaces and, therefore, an increase in surface runoff. As previously stated, construction projects that disturb more than one acre require NPDES permits.Under the NPDES permits, project proponents are required to prepare an SW PPP. Adherence to BMPs specified in the SW PPP is expected to reduce potential water quality impacts associated with this issue to a less than significant level. It is anticipated that because BMPs would be installed on the roadway, the construction of these features would be less than significant as construction would occur within an existing urban area. Because the BMPs include features to mitigate potential impacts to water quality from project drainage, the construction, operation, and maintenance of the project drainage features, including features associated with the BMPs, will not result in significant impacts to water quality. d) Have sufficient water supplies available to serve the project from existing entitlements and resources, or are new or expanded entitlements needed? No Impact.The proposed project is a roadway improvement project that will require minimal use of water during construction for dust suppression and subsurface compaction. Because the proposed project would not require water within the service area, there is no need for new water sources or water entitlements(refer to Checklist Question response XVIb).Therefore,no impacts associated with sufficient water supply would occur with implementation of the proposed project and no mitigation is required. e) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? No Impact.The proposed project would not require services provided by a wastewater treatment provider as the project is a roadway improvement project that would not generate wastewater. Therefore, no impacts related to this issue would occur and no mitigation is required. f) Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? No Impact. Solid waste collection is a "demand-responsive"service and current service levels can be expanded and funded through user fees without difficulty. However, because the proposed project consists of a roadway widening,it is anticipated that no solid waste disposal services would be required. Therefore, no impacts related to issue would occur and no mitigation is required. Ramona Expressway Widening Project •Page 57 City of San Jacinto 3.0 Environmental Checklist g) Comply with federal, state, and local statutes and regulations related to solid waste? Less Than Significant Impact.The proposed project would result in the construction and operation of new lanes on an existing roadway. During construction there would be some solid waste produced; however, the amount of solid waste would not be significant. This waste would be collected and transported to a waste facility for disposal in accordance with the City's Municipal Code Title 8, Chapter 8.34-Construction and Demolition Waste Management. During the operation of the roadway no solid waste would be generated. Because the proposed project would be required to adhere to federal,state, and local statutes and regulations concerning the disposal of solid waste inclusive of construction and demolition waste generated during construction of the additional lanes,impacts related to this issue would be reduced to a less than significant level and no mitigation is required. XVIII. MANDATORY FINDINGS OF SIGNIFICANCE a) Does the project have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? Less Than Significant with Mitigation Incorporated. As stated in this Initial Study, although the proposed project would affect the quality of the environment with respect to the habitat of a plant or animal community, the mitigation identified in the Initial Study would reduce such impacts through the provision of mitigation measures for the species that would be affected to a less than significant level Similarly, although the project would reduce habitat of a rare or endangered plant or animal, mitigation identified in the Initial Study would reduce impacts through the fencing and surveying of the site to ensure that endangered species are protected to the maximum extent possible (Mitigation Measures BIO-04 through B10-09). The project does not impact or eliminate important examples of the major periods of California history or prehistory. If during construction activities such as grading and soil excavation if any unknown subsurface historical and/or archaeological resources are uncovered,provision of Mitigation Measures CUL-01 and CUL-02 would ensure that impacts to unknown subsurface historic and/or archaeological resources are reduced to a less than significant level.Therefore,impacts related to this issue are considered to be less than significant with implementation of mitigation identified. b) Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerate"means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects.) Less Than Significant Impact. The proposed project site is currently developed with a roadway structure and is in an urban setting. The project has the potential to result in both short-term and long- term impacts to the environment.Grading and related site preparation activities are expectedto generate short-term impacts; however,while short-term impacts are anticipated to occur,the achievement of short- term environmental goals would not be at the expense of long-term environmental goals. As such, impacts related to this issue are considered to be less than significant. c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? Less Than Significant Impact. Implementation of the proposed project will not result in direct and indirect impacts to human beings, Based on the information provided; impacts are anticipated to be less Ramona Expressway Widening Project •Page 58 City of Sara Jacinto 3.0 Environmental Checklist than significant due to adherence to standard requirements and identified mitigation measures.Therefore no mitigation would be required. Ramona Expressway Widening Project •Page 59 City of San Jacinto 4.0 Mitigation Monitoring and Reporting Plan This Mitigation Monitoring and Reporting Plan has been prepared for use in implementing mitigation for the: Ramona Expressway Widening Project [Sanderson Avenue to Main Street] The program has been prepared in compliance with State law and the Initial Study(IS) prepared for the project by the City of San Jacinto. The California Environmental Quality Act(CEQA) requires adoption of a reporting or monitoring program for those measures placed on a project to mitigate or avoid adverse effects on the environment (Public Resource Code Section 21081.6). The law states that the reporting or monitoring program shall be designed to ensure compliance during project implementation. The monitoring program contains the following elements: 1) The mitigation measures are recorded with the action and procedure necessary to ensure compliance. In some instances,one action may be used to verify implementation of several mitigation measures. 2) A procedure for compliance and verification has been outlined for each action necessary. This procedure designates who will take action, what action will be taken and when, and to whom and when compliance will be reported. 3) The program has been designed to be flexible. As monitoring progresses, changes to compliance procedures maybe necessary based upon recommendations by those responsible for the program. As changes are made, new monitoring compliance procedures and records will be developed and incorporated into the program. This Mitigation Monitoring and Reporting Plan includes mitigation identified in the IS.

The Notice of Intent and Notice of Availability of the Mitigated Negative Declaration for the proposed project was published in The Press Enterprise on April 14, 2011. The California Environmental Quality Act (CEQA) requires that the City of San Jacinto decision makers consider the comments received during the public review of the Mitigated Negative Declaration prior to carrying out or approving the project(CEQA Guidelines Section 15074[b]).Comments that do not directly relate to the analysis in this document(i.e.,are outside the scope of this document)are not given Specific responses;however, all comments are included in this section so that the decision-makers may know the opinions of the commenter. The comments received regarding the Initial Study/Mitigated Negative Declaration and the responses to comments are included in this document.Two comment letters have been received.These letters include the following: Letter A: United States Fish and Wildlife Service and California Department of Fish and Game (joint letter) Letter B: The Soboba Band of Luiseno Indians Aside from the courtesy statements, introductions,and closings,individual comments within the body of each letter have been identified and numbered. A copy of each comment letter and the City's responses are included in this section. Brackets delineating the individual comments and an alphanumeric identifier have been added to the right margin of the letter. Responses to each comment identified are included on the page(s) following each comment letter. Responses to comments were sent to the agencies that provided comments. In the process of responding to the comments, there were minor revisions to the Initial Study/Mitigated Negative Declaration. None of the comments or responses constitute "significant new information" (CEQA Guidelines Section 15073.5) that would require recirculation of the Mitigated Negative Declaration or the necessity to prepare an Environmental Impact Report. 74 U.S.Fish and Wildlife Service California Department of Fish&Game Carlsbad Fish and Wildlife Office Inland Deserts Region 6010 Hidden Valley Road 3602 Inland Empire Blvd., Ste C-220 Carlsbad, California 92011 Ontario,California 91764 (760)431-9440 (909)484-0459 FAX(760)431-5902 FAX(909)481-2945 In Reply Refer To: FWS/CDFG-W RI V-08B0046-11 CPA0033 Mr. Asher Hartel MAY 0 4 2011 AiCP, Planning Director City of San Jacinto 595 South San Jacinto Avenue, Building A San Jacinto, California 92583 Subject: initial Study/Mitigated Negative Declaration for the Ramona Expressway Widening Project(Sanderson Avenue to Main Street), City of San Jacinto, California Dear Mr. Hartel: The California Department of Fish and Game (Department)and the U.S.Fish and Wildlife Service (Service),hereafter collectively referred to as the Wildlife Agencies, have reviewed the Initial Study/Mitigated Negative Declaration(Mitigated Negative Declaration) for the Ramona Expressway Widening Project. The proposed project is the widening of Ramona Expressway from Sanderson Avenue to Main Street/Lake Park Drive in the City of San Jacinto,Riverside County, California. The primary concern and mandate of the Service is the protection of public fish and wildlife resources and their habitats. The Service has legal responsibility for the welfare of migratory birds,anadromous fish, and endangered animals and plants occurring in the United States. The Service is also responsible for administering the Endangered Species Act of 1973 (Act), as amended (16 U.S.C. 1531 et seq.). The Department is a trustee agency under the California Environmental Quality Act(CEQA) and is responsible for ensuring appropriate conservation of fish and wildlife resources including rare, threatened, and endangered plant and animal species,pursuant to the California Endangered Species Act, and administers the Natural Community Conservation Planning Program (NCCP). On June 22, 2004, the Service issued a section 10(a)(1)(B)permit for the Western Riverside County Multiple Species Habitat Conservation Plan(MSHCP). The MSHCP establishes a multiple species conservation program to minimize and mitigate habitat loss and the incidental take of covered species in association with activities covered under the permit. The Department also issued Natural Community Conservation Plan Approval and Take Authorization for the MSHCP as per Section 2800,et seq.,of the California Fish and Game Code. One of the requirements of CEQA is to address any inconsistencies between a proposed project and applicable general plans and regional plans, including habitat conservation plans and natural community conservation plans, such as the MSHCP. An impact assessment of the impacts to the MSHCP as a result of this project is necessary to address CEQA. The purpose of this letter is to assess the biological analysis discussed in the Mitigated Negative Declaration relative to the policies TAKE PRIDE* & INAMERICA-=;;ft.i Mr. Asher Hartel(FWS/CDFG-WRIV-08B0046-1ICPA0033) 2 of the MSHCP to determine whether the Mitigated Negative Declaration provides an adequate 1 analysis of the project impacts on the MSHCP and whether the project is consistent with the MSHCP. The proposed project is within the jurisdiction of the City of San Jacinto,an MSHCP permittee, and the Plan Area of the MSHCP. Portions of the project are located in the MSHCP Criteria Area. Specifically,the project would occur within Criteria Cells 2893, 3098, and 3099 of the San Jacinto 2 Valley Area Plan. Conservation within these cells is to contribute to the assembly of Proposed Core 5 and to conserve grassland habitat adjacent to the San Jacinto River. The proposed project also falls within the MSHCP survey areas for burrowing owl,Los Angeles pocket mouse, and San Bernardino kangaroo rat. Surveys have not yet been completed for Los Angeles pocket mouse and San Bernardino kangaroo rat and results were not included in the Mitigated Negative Declaration. Surveys for Los Angeles pocket mouse and San Bernardino kangaroo rat need to be conducted following State and Federal approved protocols and procedures. Survey results and an assessment of the proposed project's impacts to the 3 species and their habitat needs to be included in the Mitigated Negative Declaration to not only adequately assess impacts to the project under CEQA but also to determine consistency with the MSHCP. Also, impacts to San Bernardino kangaroo rat, a Federal Endangered species, may be considered significant under CEQA and require the preparation of an Environmental Impact Report. The Wildlife Agencies acknowledge and appreciate the avoidance and minimization measures provided in the Mitigated Negative Declaration for San Bernardino kangaroo rat. However,the MSHCP requires the suitable habitat for San Bernardino kangaroo rat and Los Angeles pocket mouse be surveyed and 90 percent of the habitat with long-term conservation value be avoided. Therefore, 4 to adequately address these species under CEQA, we request the surveys be completed and assessment of habitat with long-term conservation value for these species be addressed in the Mitigated Negative Declaration. Surveys results were for the burrowing owl were also not included in the Mitigated Negative Declaration. The Mitigated Negative Declaration indicates that a burrowing owl was observed during a"habitat suitability assessment". A habitat suitability assessment is not adequate to assess impacts to burrowing owl, To adequately assess impacts under CEQA and to determine consistency with the MSHCP, burrowing owl surveys need to be conducted following Department approved methods. Surveys are to be conducted during the breeding season(March 1 through August 31),to determine if, 5 when, and how a project site is being utilized by owls. Four surveys are to be conducted between March 1 and August 31 and should be reasonably spaced during this time period. These surveys are not only necessary to adequately assess impacts to the species under CEQA, but are also required under the MSHCP. Although the Mitigated Negative Declaration provided mitigation measures for burrowing owl, these measures were limited to avoidance and minimization measures to avoid direct mortality of burrowing owl. These measures do not meet the requirements of the MSHCP(MSHCP Volume H, page B-65). Depending on the results of breeding season surveys,the proposed project may need to incorporate onsite conservation measures for the burrowing owl consistent with species-specific objective #5 of 6 the MSHCP. MSHCP species-specific objective# 5 for the burrowing owl requires that focused surveys be conducted to determine the presence of burrowing owls as part of the project review process and that the locations of this species(determined as a result of survey efforts)be conserved in accordance with procedures further described under this objective(MSHCP Volume I1, page B-65). i i Mr. Asher Hartel (FWS/CDFG-WRIV-08B0046-11CPA0033) 3 Please note that focused surveys are required to determine burrowing owl presence and address consistency with the Additional Survey Needs and Procedures and species-specific objective#5 and that pre-construction clearance surveys(species-specific objective# 6)are also required in order to 6 prevent direct mortality of owls in the event owl conservation does not occur on the project site. Preconstruction surveys are required through the life of the permit and are to be conducted no more than 30 days prior to ground disturbance. The project lies adjacent to existing conservation areas associated with the San Jacinto River. Mitigated Negative Declaration should include a discussion of the potential impacts of the proposed project on the adjacent San Jacinto River and lands conserved for the MSHCP. Potential impacts could include effects from noise, lighting, increased traffic, water quality, fuels management, and landscaping. In addition,the Mitigated Negative Declaration should address consistency with the MSHCP Guidelines Pertaining to the Urban Wildlands Interface and the Fuels Management sections of the MSHCP. According to the MSHCP Guidelines Pertaining to the Urban Wildlands Interface, projects are required to ensure that the quality and quantity of runoff discharged to the MSHCP Conservation Area is not altered in an adverse way when compared with existing conditions. We request that the Mitigated Negative Declaration address how the project will meet this policy requirement. Because the project will impact lands within the Criteria Area,a Joint Project Review(JPR) is required to document the project's consistency with the MSHCP. To date the Wildlife Agencies have not received a JPR for this Project. The JPR should be completed prior to CEQA and all surveys required for consistency with the MSHCP need to be completed and included as part of the JPR 8 package. Therefore, we recommend that the JPR is completed prior to CEQA so that the information provided in the JPR package(including appropriate surveys)can be included in CEQA document to demonstrate consistency with MSHCP. We appreciate the opportunity to provide comments on the proposed project. If you have any questions pertaining to these comments,please contact Leslie MacNair(Department)at (949)458-1754, or Karin Cleary-Rose(Service) at(760)431-9440,extension 228. Sincerely, 4t Kennon A. Corey Leslie MacNair Assistant Field Supervisor Staff Environmental Scientist U. S.Fish and Wildlife Service California Department of Fish and Game cc: Charles Landry,RCA 5.0 Response to Comments Response to Letter A United States Fish and Wildlife Service and California Department of Fish and Game (joint letter) Response to Comment A-1: The City acknowledges the purpose of the letter and its relevance to CEQA and the Western Riverside County MSHCP. Response to Comment A-2: The Biological Resources Assessment and the Initial Study prepared for the proposed project acknowledges that the project is within MSHCP Criteria Cells 2893, 3098 and 3099. The Biological Resources Assessment also contains a MSHCP Consistency Analysis that concludes the project is covered under the MSHCP as an existing road improvement (widening), per Section 7.3.5: Planned Roads within the Criteria Area of the MSHCP.The project is adjacent to the MSHCP Conservation Area;therefore,it will be consistent with the conservation objectives through compliance with Section 7.5.3: Construction Guidelines and Appendix C: Best Management Practices. Within the Criteria Cells,the project will minimize any removal of vegetation remaining within the right-of-way that is outside the actual construction site and will avoid using grass-covered land for staging or parking that is outside of the right-of-way and within the proposed Conservation Area. Response to Comment A-3: Focused surveys for the San Bernardino kangaroo rat and Los Angeles pocket mouse were not conducted based on lack of suitable habitat adjacent to the project for Phase I (Ramona Expressway from Sanderson Avenue to Eagle Road). On July 10-15, 2011 LSA biologists conducted small mammal trapping for the area of Phase II (Ramona Expressway from Eagle Road to Main Street/Lake Park Drive). The results of the surveys are included in Appendix F of this Initial Study. The surveys determined the presence of Los Angeles pocket mouse (LAPM) and the absence of San Bernardino kangaroo rat.The City has prepared a Determination of Biologically Equivalent or Superior Preservation (DBESP) in accordance to MSHCP guidelines and did go through the Public Projects Joint Project Review(JPR) process with the Riverside Conservation Agency(RCA) subsequent to the publication of the Draft Initial Study. Mitigation for direct and indirect impacts to the LAPM and Criteria Cell has been agreed upon by the RCA and the City and are provided as revised mitigation measures in the Initial Study. Response to Comment A-4: The City acknowledges the Agencies appreciation of the avoidance measures included in the IS/MND. These will be implemented for consistency with MSHCP section 6.1.4 Urban/Wildlands Interface Guidelines. Response to Comment A-5: A focused burrowing owl survey was conducted during the breeding season in May 2011,subsequent to the publication of the Draft Initial Study(refer to Appendix E).The survey results are provided in the attached report. Several ground squirrel burrows were found along the right-of-way from Sanderson Avenue to Lake Park Drive. No burrowing owls or owl sign were observed in the project site. A wintering owl was present near Potter Road during the previous conducted habitat suitability assessment survey in December 2009. Owl sign and burrowing owls were not observed at this previously occupied location between Potter Road to Sanderson Avenue. Response to Comment A-6:Refer to Response to Comment A-5.A pre-construction nesting and burrowing owl survey will be conducted within 30-day of ground disturbance(refer to Mitigation Measure BIO-03 below). BIO-03 A pre-construction burrowing owl survey shall be conducted by a qualified biologist within 30 days prior to ground-disturbing activities for each phase of construction in order to determine whether any burrowing owls are occupying potentially suitable desert scrub habitat. If surveys determine that burrowing owls occupy the site,a burrowing owl mitigation plan shall be prepared, 78 5.0 Response to Comments subject to approval by the California Department of Fish and Game(CDFG).Mitigation measures identified in the plan shall include: Burrows located outside the project area(within 250 feet)shall be flagged for avoidance. Unoccupied burrows located in the project area shall be covered to prevent owls from reoccupying the burrows prior to construction. • If active owl burrows are discovered within 250 feet of proposed work areas, the owls shall be relocated from the burrows using either active or passive techniques as recommended by the CDFG.Owl relocation, as well as discouragement of owls from returning to the site,shall occur in the following manner: 1) During the non-breeding season (September 1 through January 31), burrowing owls occupying proposed work areas shall be evicted by passive relocation. Passive relocation shall include the installation of one-way doors on burrow entrance.Any active burrow shall be replaced off-site in adjacent habitat with an artificial burrow. Burrows shall be inspected with a fiber optic camera to ensure animals do not remain in the den. 2) If construction is scheduled during the breeding season(February 1 through August 31) and prior to the relocation of the owls, a 250-foot protective buffer shall be maintained around burrows occupied by owls until the young have fledged. Other actions could include passive relocation if it is determined that owls have not begun laying eggs or postponement of construction in the area until the young are fledged and no longer dependent upon the nest burrow. 3) Once fledglings are capable of independent survival and adult non-breeding owls have successfully been relocated off site, potential owl burrows shall be collapsed in order to keep the owls from returning. Response to Comment A-7: The project's indirect effects to the existing MSHCP Conserved Lands (San Jacinto River) will be mitigated through compliance with MSHCP Section 6.1.4 Guidelines pertaining to the Urban/Wildlands Interface,Section 7.3.5:Planned Roads within the Criteria Area,Section 7.5.3:Construction Guidelines,and Appendix C: Best Management Practices.Within the Criteria Cells,the project will minimize any removal of vegetation remaining within the right-of-way that is outside the actual construction site and will avoid using grass-covered land for staging or parking that is outside of the right-of-way and within the proposed Conservation Area. Implementation of the proposed project would not significantly alter the existing drainage pattern of the project site, resulting in a less than significant impact to hydrology. It is anticipated that because the project site would add a minimal amount of impervious surfaces, the effect of the proposed project on the velocity or volume of downstream flows would be negligible, and no substantial hydraulic changes or erosion would occur.Additional information pertaining avoidance and minimization measures to be implemented for MSHCP consistency has been added to the Initial Study under Biological Resources. Response to Comment A-8: The City has completed a Public Projects Joint Project Review(JPR)with the Riverside Conservation Agency (RCA) subsequent to the publication of the Draft Initial Study. The JPR submittal is contained in Appendix H of the Initial Study and the RCA's concurrence is contained in Appendix I. 79 OF Ltljs�� �� 2a May 25, 2011 �O 1 Attn: Mike Hasapes � cz Planning Technician Community Development Department 595 South San Jacinto Avenue EST.JUNE 19,1883 San Jacinto, CA 92583 Re: Initial Study with Proposed Mitigated Negative Declaration for the Ramona Expressway Widening Project, City of San Jacinto, California (LSA Project No.TLK1002) The Soboba Band of Luiseno Indians appreciates your observance of Tribal Cultural Resources and their preservation in your project. The information provided to us on said project has been assessed through our Cultural Resource Department, where it was concluded that although it is outside the existing reservation, the project area does fall within the bounds of our Tribal Traditional Use Areas. This project location is in close proximity to known village sites and is a shared use area that was used in ongoing trade between the Luiseno and Cahuilla tribes. Therefore it is regarded as highly sensitive to the people of Soboba. Soboba Band of Luiseno Indians is requesting the following: 1. To initiate a consultation with the Project Developer and Land owner. B-1 2. The transfer of information to the Soboba Band of Luiseno Indians regarding the progress of this B-2 project should be done as soon as new developments occur. 3. Soboba Band of Luiseno Indians continues to act as a consulting tribal entity for this project. B-3 4. Working in and around traditional use areas intensifies the possibility of encountering cultural resources during the construction/excavation phase. For this reason the Soboba Band of Luisefio B-4 Indians requests that Native American Monitor(s)from the Soboba Band of Luiseno Indians Cultural Resource Department to be present during any ground disturbing proceedings. Including surveys and archaeological testing. 5. Request that proper procedures be taken and requests of the tribe be honored B-5 (Please s e the attachment) Sincere Jo eph nti os Sob b Cultural Resource Department P.O.

Ceremonial items and items of cultural patrimony reflect traditional religious beliefs and practices of the Soboba Band. The Developer should agree to return all Native American ceremonial items and items of cultural patrimony that may be found on the project site to the Soboba Band for appropriate treatment. In addition, the Soboba Band requests the return of all other cultural items (artifacts) that are recovered during the course of archaeological investigations. When appropriate and agreed upon in advance, the Developer's archeologist may conduct analyses of certain artifact classes if required by CEQA, Section 106 of NHPA, the mitigation measures or conditions of approval for the Project. This may include but is not limited or restricted to include shell,bone,ceramic, stone or other artifacts. The Developer should waive.any and all claims to ownership of Native American ceremonial and cultural artifacts that may be found on the Project site. Upon completion of authorized and mandatory archeological analysis, the Developer should return said artifacts to the Soboba Band within a reasonable time period agreed to by the Parties and not to exceed (30) days from the initial recovery of the items. Treatment and Disposition of Remains. A. The Soboba Band shall be allowed, under California Public Resources Code§ 5097.98 (a), to (1) inspect the site of the discovery and (2) make determinations as to how the human remains and grave goods shall be treated and disposed of with appropriate dignity. B. The Soboba Band, as MLD, shall complete its inspection within twenty-four(24)hours of receiving notification from either the Developer or the NAHC, as required by California Public Resources Code§ 5097.98 (a). The Parties agree to discuss in good faith what constitutes "appropriate dignity" as that term is used in the applicable statutes. C. Reburial of human remains shall be accomplished in compliance with the California Public Resources Code § 5097.98 (a) and (b). The Soboba Band, as the MLD in consultation with the Developer, shall make the final discretionary determination regarding the appropriate disposition and treatment of human remains. D. All parties are aware that the Soboba Band may wish to rebury the human remains and associated ceremonial and cultural items (artifacts)on or near, the site of their discovery, in an area that shall not be subject to future subsurface disturbances. The Developer should accommodate on-site reburial in a location mutually agreed upon by the Parties. E. The term "human remains" encompasses more than human bones because the Soboba Band's traditions periodically necessitated the ceremonial burning of human remains. Grave goods are those artifacts associated with any human remains. These items, and other funerary remnants and their ashes are to be treated in the same manner as human bone fragments or bones that remain intact. Coordination with County Coroner's Office. The Lead Agencies and the Developer should immediately contact both the Coroner and the Soboba Band in the event that any human remains are discovered during implementation of the Project. If the Coroner recognizes the human remains to be those of a Native American, or has reason to believe that they are those of a Native American, the Coroner shall ensure that notification is provided to the NAHC within twenty-four(24)hours of the determination, as required by California Health and Safety Code § 7050.5 (c). Non-Disclosure of Location Reburials. It is understood by all parties that unless otherwise required by law, the site of any reburial of Native American human remains or cultural artifacts shall not be disclosed and shall not be governed by public disclosure requirements of the California Public Records Act. The Coroner, parties, and Lead Agencies, will be asked to withhold public disclosure information related to such reburial, pursuant to the specific exemption set forth in California Government Code § 6254 (r). Ceremonial items and items of cultural patrimony reflect traditional religious beliefs and practices of the Soboba Band. The Developer agrees to return all Native American ceremonial items and items of cultural patrimony that may be found on the project site to the Soboba Band for appropriate treatment. In addition, the Soboba Band requests the return of all other cultural items (artifacts) that are recovered during the course of archaeological investigations. Where appropriate and agreed upon in advance, Developer's archeologist may conduct analyses of certain artifact classes if required by CEQA, Section 106 of NHPA, the mitigation measures or conditions of approval for the Project. This may include but is not limited or restricted to include shell, bone, ceramic, stone or other artifacts. 5.0 Response to Comments Response to Letter B The Soboba Band of Luiseno Indians Response to Comment B-1: The proposed project does not require a General Plan or Specific Plan amendment and does not fall under the requirements of SB318;therefore,no formal consultation between the City and the Tribe is required. Response to Comment B-2: The proposed project is the widening of the existing Ramona Expressway from Sanderson Avenue to Main Street. If there are changes to the proposed project description,the City will notify the Tribe as requested. The project is not a traditional development project so there will be no additional development that will occur as a result of this project. Response to Comment B-3: The City recognizes that the Tribe is a consulting tribal entity for this project.In addition, the Tribe was contacted and consulted by LSA Associates, Inc. refer to page 6 "Native American Scoping"in the Cultural Resources Assessment prepared for the proposed project located in Appendix C.The City received the same letter as a response to the consultation(October 21,2010)as the current letter dated May 25, 2011. Response to Comment 13-4: The Cultural Resources Assessment prepared for the proposed project (Appendix C) detailed that, no resources have been recorded within the project boundaries. However, two historic houses immediately adjacent to the project boundaries have been recorded. Based on the 43 previously conducted cultural resources studies, 61 historical resources and 3 prehistoric/cultural value resources have been identified within a one-mile radius of the project's boundaries. None of these resources is located within the project boundaries.No cultural resources were identified within the project boundaries by the archival research conducted on October 5,2010,and during field surveys conducted on October 14 and 15, 2010. While no cultural resources were identified within the project boundaries during research and field surveys, construction activity (particularly grading and soil excavation) could potentially adversely affect unknown subsurface historical and/or archaeological resources and implementation of Mitigation Measures CUL-01 and CUL-02 would ensure that impacts to unknown subsurface historic and/or archaeological resources are reduced to a less than significant level. Measure CUL-01 ensures that monitoring during construction will occur and if it doesn't any discoveries of cultural resources will be evaluated and if necessary protected. Response to Comment B-5: The proposed project is a City initiated project and will not be undertaken by a private developer. Regardless of that fact, the City acknowledges the proper procedures outlined in the letter's attachment and will follow them if and when it is appropriate to do so. 83 APPENDIX A RAMONA EXPRESSWAY EXPANSION AIR QUALITY STUDY RAMONA EXPRESSWAY EXPANSION AIR QUALITY STUDY City of San Jacinto, California v a a c m N \ A \d �tpy \ � t \ V ai Q � a :Ma,n 4t.

A 1 .0 Introduction RK ENGINEERING GROUP, INC. (RK) is pleased to provide this Air Quality Impact study for the Ramona Expressway (SR-79) Expansion project located in the City of San Jacinto. The project site is located along the Ramona Expressway (SR-79) segment between Sanderson Avenue and Lake Park Drive, as shown in Exhibit A. The site plan for the project is shown in Exhibit B. The purpose of this study is to assess potential air quality impacts associated with the Ramona Expressway (SR-79) Expansion project by investigating the existing meteorological and climate conditions in the project area, identifying the project related sources of potential air quality impact and predicting the future air quality impact levels. As a result of this effort, RK has prepared a list of recommended emission reduction measures, outlined in Section 5.0 Mitigation Recommendations, which should be implemented as part of the development project to reduce air quality impacts. The study evaluates the air quality impacts associated with the project. The project will be completed in two (2) phases. Phase 1 consists of expanding the existing two-lane roadway to four (4) lanes, two (2) in each direction, and extends between State Street and Lake Park Drive. Phase 2 consists of expanding the existing four-lane roadway to six (6) lanes, three (3) lanes in each direction, and extends between State Street and Sanderson Avenue. The entire project extends approximately 12,610 ft (2.388 miles) and will result in a construction area of approximately 370,000 square feet (8.49 acres). The project is expected to start in late 2010 and the estimated duration is approximately ten (10) to fourteen (14) months. The proposed project was analyzed as follows: 1.4 months for grubbing and land clearing, 5.6 months for grading and excavation, 4.9 months for drainage, utilities, and sub-grade, and 2.1 months for paving. 1-1 The results of the analysis indicate that construction operation and dust from the project site will represent the principle sources of on-site air quality impacting the surrounding area. With implementation of the recommended mitigation measures, construction emissions are not expected to exceed South Coast Air Quality Management District (SCAQMD) regional and local thresholds during the buildout of the project. Localized thresholds are not expected to be exceeded during construction. 1-2 2.0 Existing Conditions 2.1 Regional Climate and Meteorology The climate of the City of San Jacinto area, as with all of Southern California, is governed largely by the strength and location of the semi-permanent high pressure center over the Pacific Ocean and the moderating effects of the nearby vast oceanic heat reservoir. The Local semi-arid climatic condition is characterized by very warm summers, mild winters, and moderate rainfall. This weather pattern is at times interrupted by periods of extremely hot weather, winter storms, or Santa Ana Winds. Humidity ranges between 70 percent on the Coast and 57 percent in the Eastern Basin. Unfortunately, the same climatic conditions that create this desirable Mediterranean-like climate combine to severely restrict the ability of the local atmosphere to disperse the large volumes of air pollution generated by the population and industry attracted in part by the climate. The City of San Jacinto is situated in an area where the pollutants generated in coastal portions of the Los Angeles basin undergo photochemical reactions and then move inland across the project site during the daily sea breeze cycle. Despite dramatic improvement in air quality in the local area throughout the 1980s, the project site is nevertheless, expected to continue to experience some unhealthful air quality for at least the next decade. Temperatures in the project vicinity average 80 degrees Fahrenheit annually with summer afternoons in the mid 90s and winter mornings in the upper 40s. It should also be noted that temperatures above 100 degrees have been recorded in recent years. On average the warmest months are July and August and the coolest month is December. 2-1 In contrast to the slow annual variation of temperature, precipitation is highly variable seasonally. Rainfall in the City of San Jacinto area averages 13 inches annually and falls from late November to early April with February yielding the greatest amount of precipitation and summers almost completely dry. Because much of the rainfall comes from the fringes of mid-latitude storms, a shift in the storm track of a few hundred miles can mean the difference between a very wet year and a year with drought conditions. Winds across the project area are an important meteorological parameter because they control both the initial rate of dilution of locally generated air pollutant emissions as well as their regional trajectory. Daytime winds across City of San Jacinto show a daytime onshore flow from the NW averaging 6-8 mph. During the daytime, air emissions generated by urbanized coastal areas are transported eastward toward the region without generating any localized air quality impacts. The drainage winds which move slowly across the area have some potential for localized stagnation. Fortunately, these winds have their origin in the San Gabriel Mountains where background pollution levels are low such that any localized contributions do not create any unhealthful impacts. The wind distribution is such that nominal project-related air quality impacts occur more on a regional scale rather than in the immediate Grand Terrace area. One other important wind condition may occur when a high pressure center forms over the western United States with sinking air forced seaward through local canyons and mountain passes. The air warms by compression and relative humidities drop dramatically. The dry, gusty winds from the N-NE create dust nuisance potential around areas of soil disturbance such as construction sites and sometimes create serious visibility and safety problems for vehicles on area freeways. Z-Z In conjunction with the two dominant wind regimes that affect the rate and orientation of horizontal pollutant transport, there are two similarly distinct types of temperature inversions that control the vertical depth through which pollutants are mixed. The summer on-shore flow is capped by a massive dome of warm, sinking air which caps a shallow layer of cooler ocean air. These marine/subsidence inversions act like a giant lid over the basin. They allow for local mixing of emissions, but they confine the entire polluted air mass within the basin until it escapes into the desert or along the thermal chimneys formed along heated mountain slopes. In winter, when the air near the ground cools while the air aloft remains warm, radiation inversions are formed that trap low-level emissions such as automobile exhaust near their source, As background levels of primary vehicular exhaust rise during the seaward return flow, the combination of rising non-local baseline levels plus the emissions trapped locally by these radiation inversions creates micro-scale air pollution "hot spots" near freeways, shopping centers and other traffic concentrations. Because the incoming air draining off the mountains during nocturnal radiation inversion conditions is relatively clean, the summer subsidence inversions are a far more critical factor in determining the City of San Jacinto area air quality than the winter time local trapping inversions. 2.2 Ambient Air Quality In order to gauge the significance of the air quality impact of the proposed Ramona Expressway (SR-79) Expansion project, those impacts, together with existing background air quality levels, must be compared to the applicable ambient air quality standards. These standards are the levels of air quality considered safe, with an adequate margin of safety, to protect the public health and welfare. They are designed to protect those people most susceptible to further respiratory distress such as asthmatics, the elderly, very young children, people already weakened by other disease or illness, and persons engaged in strenuous work or exercise, called 2-3 "sensitive receptors." Healthy adults can tolerate occasional exposure to air pollutant concentrations considerably above these minimum standards before adverse effects are observed. Recent research has shown, however, that chronic exposure to ozone (the primary ingredient in photochemical smog) may lead to adverse respiratory health even at concentrations close to the ambient standard. 2.2.1 Ambient Air Quality Standards National Ambient Air Quality Standards (AAQS) were established in 1971 for six pollution species with states retaining the option to add other pollutants, require more stringent compliance, or to include different exposure periods. The initial attainment deadline of 1977 was extended several times in air quality problem areas like Southern California. In 2003, the Environmental Protection Agency (EPA) adopted a rule which extended and established a new attainment deadline for ozone for the year 2021 . Because the State of California had established AAQS several years before the federal action and because of unique air quality problems introduced by the restrictive dispersion meteorology, there is considerable difference between state and national clean air standards. Those standards currently in effect in California are shown in Table 1. Sources and health effects of various pollutants are shown in Table 2. The Federal Clean Air Act Amendments (CAAA) of 1990 required that the U.S. Environmental Protection Agency (EPA) review all national AAQS in light of currently known health effects. EPA was charged with modifying existing standards or promulgating new ones where appropriate. EPA subsequently developed standards for chronic ozone exposure (8+ hours per day) and for very small diameter particulate matter (called "PM-2.5"). National AAQS were adopted on July 17, 1997. Planning and enforcement of the federal standards for PM-2.5 and for ozone (8-hour) were challenged by trucking and manufacturing organizations. In a unanimous decision, the U.S. Supreme Court ruled that EPA did not require specific 2-4 congressional authorization to adopt national clean air standards. The Court also ruled that health-based standards did not require preparation of a cost-benefit analysis. The Court did find, however, that there was some inconsistency between existing and "new" standards in their respective attainment schedules. Such attainment-planning schedule inconsistencies centered mainly on the 8-hour ozone standard. EPA subsequently agreed to downgrade the attainment designation for a large number of communities to "non-attainment" for the 8-hour ozone standard. Because the South Coast Air Basin is still far from attaining the 1-hour federal standard, the 8-hour ozone non-attainment designation will not substantially alter the attainment planning process. The compliance deadline for the 8-hour ozone standard has been extended to 2021. Evaluation of the most recent data on the health effects of inhalation of fine particulate matter prompted the California Air Resources Board (ARB) to recommend adoption of the statewide PM-2.5 standard that is more stringent than the federal standard. This standard was adopted on June 20, 2002. The State PM-2.5 standard is more of a goal in that it does not have specific attainment planning requirements like a federal clean air standard, but only requires continued progress towards attainment. Similarly, the ARB extensively evaluated health effects of ozone exposure. A new state standard for an 8-hour ozone exposure was adopted in April 2005, which mirrors the federal standard. The California 8-hour ozone standard of 0.07 ppm is more stringent than the federal 8-hour standard of 0.075 ppm. The state standard, however, does not have a specific attainment deadline. California air quality jurisdictions are required to make steady progress toward attaining state standards, but there are no hard deadlines or any consequences of non-attainment. As part of the same re-evaluation process, the ARB is anticipated to adopt a new annual state standard for nitrogen dioxide (NO2) that is more stringent than the corresponding federal standard. 2-5 Of the standards shown in Table 1, those for ozone (03), carbon monoxide (CO), and particulate matter (PM-10) are exceeded at times in the South Coast Air Basin. They are called "non-attainment pollutants." The CO standard is currently met in the basin, and re-designation to "attainment/maintenance" was adopted in October 2007. Because of the variations in both the regional meteorology and in area-wide differences in levels of air pollution emissions, patterns of non-attainment have strong spatial and temporal differences. 2.2.2 Air Quality Planning The Federal Clean Air Act (1977 Amendments) required that designated agencies in any area of the nation not meeting national clean air standards must prepare a plan demonstrating the steps that would bring the area into compliance with all national standards. The South Coast Air Basin (SCAB) could not meet the deadline for ozone, nitrogen dioxide, carbon monoxide, or PM-10. In the SCAB, the agencies designated by the governor to develop regional air quality plans are the SCAQMD and the Southern California Association of Governments (SCAG), The two agencies first adopted an Air Quality Management Plan (AQMP) in 1979 and revised it several times as earlier attainment forecasts were shown to be overly optimistic. The 1990 Federal Clean Air Act Amendment (CAAA) required that all states with air- sheds with "serious" or worse ozone problems submit a revision to the State Implementation Plan (SIP). Several amendments to the SIP have been proposed, revised and approved over the past decade. The most current regional attainment emissions forecast for ozone precursors (ROG and NOx) and for carbon monoxide (CO) is shown in Table 3. The Air Quality Management District (AQMD) adopted an updated clean air "blueprint" in August 2003. The 2003 AQMP was approved by the EPA in 2004. The Air Quality Management Plan (AQMP) outlines the air pollution measures 2-6 needed to meet federal health-based standards for ozone by 2010 and for particulates (PM-10) by 2006. Components of the 2003 air plan include: • How the federal standard for CO will be maintained. • Control measures to further reduce emissions from business, industry and paints. • Measures to be adopted by CARB and EPA to further reduce pollution from: ➢ Cars ➢ Trucks ➢ Construction equipment ➢ Aircraft ➢ Ships ➢ Consumer products With re-designation of the air basin as non-attainment for the 8-hour ozone standard (adopted June 1, 2007), preparation of a new attainment plan was required. The attainment date will slip from 2010 to 2021 . This plan shifts most of the one-hour ozone standard attainment strategies to the 8-hour standard. The 2007 AQMP recognizes the interaction between photochemical processes that create both ozone and the smallest airborne particulates (PM-2.5). The 2007 AQMP is therefore a coordinated plan for both pollutants. Key emissions reductions strategies in the updated air quality plan include: • Ultra-low emissions standards for both new and existing sources (including on-and-off-road heavy trucks, industrial and service equipment, locomotives, ships and aircraft). • Accelerated fleet turnover to achieve benefits of cleaner engines. • Reformulation of consumer products. • Modernization and technology advancements from stationary sources (refineries, power plants, etc.). 2-7 2.3 Local Air Quality The proposed project is located within an area monitored by the South Coast Air Quality Management District (SCAQMD). Existing and probable future levels of air quality around the project area can be best inferred from ambient air quality measurements conducted by SCAQMD at their various continuous monitoring stations. The nearest air quality monitoring station in relation to the project site for Ozone and PM- 10 is at the Perris Valley monitoring station (# 4149). The nearest air quality monitoring station for Carbon Monoxide and Nitrogen Dioxide is at the Lake Elsinore monitoring station (# 4158). The nearest air quality monitoring station for ultra-fine particulates (PM-2.5) is at the Metropolitan Riverside County 1 monitoring station (# 4144). Data from the Metropolitan Riverside County 1 and Lake Elsinore monitoring stations were used only where data was not available from the closest monitoring station (Perris Valley). These stations measure both regional pollution levels such as smog, as well as primary vehicular pollution levels near busy roadways such as carbon monoxide or nitrogen oxides. Table 4 is a 5-year summary of monitoring data for the major air pollutants compiled from these two air monitoring stations. From this data the following conclusions can be drawn: 1. Photochemical smog (ozone) levels frequently exceed standards. The 1-hour state was violated an average of 51 days a year in the last five years near the City of San Jacinto area. The federal 8-hour standard has been exceeded an average of 31 days a year within the last five years. While ozone levels are still high, they are much lower than 10 to 20 years ago. Attainment of all clean air standards in the project vicinity is not likely to occur soon, but the severity and frequency of violations is expected to continue to slowly decline during the current decade. 2-8 2. PM-10 levels have exceeded the state 24-hour standard on approximately 27.2 percent of all measurement days. The three times less stringent federal 24 hour-standard was not exceeded in the past five years. Year to year fluctuations of overall maximum 24-hour PM-10 levels seem to follow no discernable trend. 3, PM-2.5 Ultra-Fine Particulates 65 jtg/m3 readings have exceeded the federal 24-hour PM-2.5 ambient standard an average of 1,1 percent of the days data was collected in the last five years. PM-2.5 > 35 /tg/m3 have exceeded the federal 24-hour PM-2.5 ambient standard an average of 11 percent of the days data was collected over the past two years, as data is only available for the most recent years, 4. With the adoption of the revised lower Nitrogen Dioxide Annual Average Concentration > 0.030 ppm level, the ARB's annual standard in 2006 and 2007 was not exceeded. 5. More localized pollutants such as carbon monoxide, sulfur dioxide, etc. are very low near the project site because background levels in San Jacinto City never exceed allowable levels. There is substantial excess dispersive capacity to accommodate localized vehicular air pollutants such as NOx or CO without any threat of violating applicable AAQS. 2-9 THIS PAGE INTENTIONALLY LEFT BLANK 2-10 3.0 Study Method and Procedure The air quality study analyzes potential pollutants and contaminant impacts from the project site to a sensitive receiver or receptor. The analysis methodology utilized procedures outlined in the SCAQMD 1993 "CEQA Air Quality Handbook" where appropriate. In areas where more site-specific information was available beyond the default values recommended in the handbook, they were used to supplement the AQMD- suggested input parameters. Construction emissions for the project site were calculated using the Road Construction Emission Model, Version 6.3.1, developed by the Sacramento Metropolitan Air Quality Management District. 3.1 SMAQMD Road Construction Emissions Model Utilizing the Road Construction Emissions Model, Version 6.3.1 developed by the Sacramento Metropolitan Air Quality Management District, an air quality assessment was calculated for construction emissions for the project phases. The air quality study is consistent to the expected general time line for the project completion. 3.1.1 Construction Emissions Model Average daily PM-10 emissions during site grading and other disturbance are stated in the SCAQMD for projects in southern California CEQA Handbook to be 26.4 pounds per acre. Enhanced dust control procedures such as continual soil wetting, use of supplemental binders, early paving, etc, can achieve an even higher PM-10 control efficiency. Daily, emissions with use of reasonably available control measures (RACMs) for PM-10 can reduce emission levels to around 10 pounds per acre per day. The default value used is 20 Ibs per day. With the use of best available control measures (BACMs) the SMAQMD computer model predicts that 3-1 emissions can be reduced to 1-11 pounds per acre per day (assuming 3 acres maximum area disturbed per day), as shown on the SMAQMD analysis printouts provided in the Appendix A. 3.2 Local Significance Threshold (LST) The SCAQMD has developed analysis parameters to evaluate ambient air quality on a local level in addition to the more regional emissions-based thresholds of significance. These analysis elements are called Local Significance Thresholds (LSTs). LSTs were developed in response to Governing Board's Environmental Justice Enhancement Initiative 1-4 and the LST methodology was provisionally adopted in October 2003 and formally approved by SCAQMD's Mobile Source Committee in February 2005. LSTs are only applicable to the following criteria pollutants: oxides of nitrogen (NOx), carbon monoxide (CO), and particulate matter (PM-10 and PM-2.5). For general development projects, LSTs are generally only applicable to the construction phase. LSTs represent the maximum emissions from a project that are not expected to cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standard, and are developed based on the ambient concentrations of that pollutant for each source receptor area and distance to the nearest sensitive receptor. 3-2 4.0 Future Air Quality Environment and Impacts This purpose of this study is to determine if the Ramona Expressway (SR-79) Expansion project will have any air quality impacts. The potential impacts are discussed in the following section. The entire project extends approximately 12,610 ft (2.388 miles) and will result in a construction area of approximately 370,000 square feet (8.49 acres). 4.1 Standards of Significance Many air quality impacts from dispersed mobile sources, i.e., the dominant pollution generators in the basin, often occur hours later and miles away after photochemical processes have converted primary exhaust pollutants into secondary contaminants such as ozone. The incremental regional air quality impact of any individual source is generally immeasurably small. The SCAQMD has therefore developed suggested significance thresholds based on the volume of pollution emitted rather than on actual ambient air quality because the direct air quality impact of a project is not quantifiable on a regional scale. The 1993 SCAQMD Handbook (as subsequently revised) states that any projects in the SCAB (South Coast Air Basin) with daily emissions that may exceed any of the thresholds should be considered as having an individually and cumulatively significant air quality impact. Table 5 shows the current SCAQMD Air Quality Significance Thresholds, Additional indicators should be used as screening criteria to evaluate the need for further analysis with respect to air quality. Whenever possible, the project should be evaluated in a quantitative analysis; otherwise a qualitative analysis is appropriate. The additional significance thresholds include whether the: • Project may interfere with the attainment of the federal or state ambient air quality standards by either violating or contributing to an existing or projected air quality violation. 4-1 • Project may result in population increases within the regional statistical area which would be in excess of that projected in the AQMP. • Project may generate vehicle trips that became a CO hot spot. • Project might have the potential to create or be subjected to objectionable odors. • Project may have hazardous materials on-site and could result in an accidental release of air toxic emissions. • Project may involve disposal of hazardous waste • Project may involve being occupied by sensitive receptors near a facility that emits air toxics or near CO hot spots. • Project may emit carcinogenic air contaminants that may pose a cancer risk. 4.2 Construction Activity Impact Temporary construction activity emissions will occur during project build-out. Such emissions include on-site generation of dust and equipment exhaust, and off-site emissions from construction employee commuting and/or trucks delivering building materials. Because of their temporary nature, air quality impacts from construction have often been considered as individually less-than-significant. Also, construction activity emissions are difficult to quantify, since the exact type and amount of equipment that will be used or the acreage that may be disturbed on any given day in the future is not known with any reasonable certainty. The emphasis in environmental documents relative to construction activity emission impacts has therefore been to minimize the emissions as fully as possible through comprehensive mitigation even if the exact amount of emissions cannot be precisely quantified. Short-term construction impacts may be generated by soil disturbance and equipment exhaust. Dust is normally the primary concern during construction of 4-2 new buildings and infrastructure. Because such emissions are not amenable to collection and discharge through a controlled source, they are called "fugitive emissions." Emission rates vary as a function of many parameters (soil silt, soil moisture, wind speed, area disturbed, number of vehicles, depth of disturbance or excavation, etc.). Regulatory agencies typically use one universal factor based on the area disturbed assuming that all other input parameters into emission rate prediction fall into mid-range average values. This assumption may or may not necessarily be applicable to site-specific conditions on the Ramona Expressway (SR-79) Expansion project site. Emissions estimates for project-specific fugitive dust sources are therefore characterized by a considerable degree of imprecision. The entire project site occupies approximately 8.49 acres. The entire site will not be under simultaneous disturbance. A 3-acre maximum area disturbed per day default was used for the average daily grading disturbance "footprint" during the grading phase. PM-10 emissions will be below the PM-10 significance thresholds with the use of "standard" dust control measures. However, because the basin is non-attainment for PM-10, use of best available control measures (BACMs) for dust is nevertheless required. Current research in particulate exposure health effects suggests that the most adverse effect derives from ultra-small diameter particulate matter comprised of chemically reactive pollutants such as sulfates, nitrates or organic material. A national clean air standard for particulate matter of 2.5 microns or smaller in diameter (called "PM-2.5") was adopted in 1997. Very little construction activity particulate matter is in the PM-2.5 range. Soil dust is also more chemically benign than typical urban atmospheric PM-2.5. In addition to fine particles that remain suspended in the atmosphere semi- indefinitely, construction activities generate many larger particles with shorter 4-3 atmospheric residence times. This dust is comprised mainly of large diameter inert silicates that are chemically non-reactive and are further readily filtered out by human breathing passages. These fugitive dust particles are therefore more a potential soiling nuisance as they settle out on parked cars, outdoor furniture, or landscape foliage than they are an adverse health hazard. Any dust nuisance potential will be minimized, however, by a combination of mandatory control programs and the relatively short dust deposition distance (<100 feet) for large- dust particles. During Santa Ana wind conditions, large particles can be carried much farther, typically from NW to SW. During these conditions, there are no sensitive receivers located in the approximate downwind direction; however, the creation of visible dust plumes from disturbed soil is prohibited by SCAQMD Rule 403. Provisions for enhanced dust control must be made for occasional Santa Ana wind conditions. Construction activity air quality impacts occur mainly in close proximity to individual disturbance areas. However, there may be some "spill-over" into the surrounding community. That spill-over may be physical as vehicles drop or carry out dirt or silt is washed into public streets. Passing non-project vehicles then pulverize the dirt to create off-site dust impacts. Spill-over may also occur through congestion effects. Construction may entail roadway encroachment, detours, land closures and competition between construction vehicles (trucks and contractor employee commuting) and ambient traffic for available roadway capacity. Emissions controls require good housekeeping procedures and a construction traffic management plan that maintains such "spill-over" effects at a less-than-significant level. 4.2.1 Vehicle Emissions Exhaust emissions will result from on- and off-site heavy equipment during grading. Emissions will also be generated during finish construction, especially during the application of paints or other coatings. The types and numbers of equipment will vary among contractors such that such emissions cannot be quantified with 4-4 certainty. The assumed equipment for various phases of construction is shown in Table 6. The SMAQMD computer model was used to estimate maximum daily emissions during various phases of construction. The results (pound/day) and are shown in Table 7. Construction equipment will emit diesel particulate matter (DPM) that is a known carcinogen. The cancer risk associated with such exposure is based on a 70-year, 365 day/year, 24 hour/day outdoor exposure. Grading is estimated to occur for approximately 5 to 6 months. It is important to note that grading will only occur during weekday working hours over the course of an entire year, rather than non- stop for 70 years. The closest populations exposed to potential construction activity are residential uses north and south of the Ramona Expressway. Residences are often unoccupied during the construction work-day, and exterior residential uses are limited in duration compared to the 24/hour per day assumption. Any public health risk from construction equipment DPM exposure is insignificant based upon exposure duration and intensity. 4.2.2 Local Significance The worst-case average daily grading disturbance "footprint" will be 3 acres. LST pollutant concentration data for construction on a 5 acre disturbed site is referenced from the SCAQMD 2D07 Thresholds for Construction. The data represents the appropriate Source Receptor Area (Hemet San Jacinto Valley) for 3-acre, 2-acre, and 5-acre sites for a source-receptor distance of 50 meters to any sensitive receptors near the site. Table 8 indicates that all mitigated emissions are below LST thresholds during project construction. 4-5 4.3 Green House Gas Emissions Construction equipment will generate greenhouse gas {GHG} emissions possibly associated with currently observed global warming. California has adopted several initiatives to reduce GHG emissions from combustion sources. Obviously, no single project or jurisdiction generates enough GHG to impact global climate. However, the cumulative impact of all combustion of fossil fuels may have global implications. Use of modern diesel engines, required to mitigate NOx impacts, will have a small GHG emissions reduction benefit from increased combustion efficiency. In the absence of any GHG thresholds of emissions significance or methodology to analyze such impacts, the use of maximally efficient diesel-fueled equipment is believed to mitigate any cumulative GHG impacts as much as is practical. Currently, the SCAQMD is devising an acceptable methodology to properly analyze GHG. 4-6 5.0 Mitigation Recommendations Recommended emissions reduction measures for construction activities are outlined in the sections below. If implemented as part of the proposed project, these measures will yield a reduction in air quality impacts associated with the development. 5.1 Vehicle Emissions As described in Section 4.3, construction of the Ramona Expressway (SR-79) Expansion project will have a less than significant impact from equipment emissions on air quality from heavy construction equipment and vehicles. The following measures are recommended to reduce impact during project construction. Construction equipment shall be maintained in proper tune. • Utilize gasoline or electricity-powered equipment instead of diesel equipment whenever possible. Suspend use of heavy construction equipment during first stage smog alerts. • All construction vehicles shall be prohibited from excessive idling. • Encourage use of "clean diesel" equipment if modified engines (catalyst equipped or newer Moyer Program retrofit) are available at a reasonable cost. 5.2 Fugitive Dust Emissions and Control To reduce fugitive dust emissions during construction, the use of best available control measures (BACM) shall be implemented during grading. The menu of enhanced dust control measures includes the following: Water all active construction areas three times daily. + Cover all haul trucks or maintain at least 2 feet of freeboard. 5-1 Pave or apply water four times daily to all unpaved parking or staging areas. Reduce speed on unpaved roads to less than 15 mph. • Sweep or wash any site access points within 30 minutes of any visible dirt deposition on any public roadway. Cover or water twice daily any on-site stockpiles of debris, dirt or other dusty material. Suspend all operations on any unpaved surface if winds exceed 25 mph. Hydroseed or otherwise stabilize any cleared area which is to remain inactive for more than 96 hours after clearing is completed. 5.3 Off-Site Impacts Based on the description of the proposed project, the following are recommendations to help reduce the potential air quality impact to the surrounding community. These recommendations can help further mitigate the potential impact to daily construction activities. Encourage car pooling for construction workers. • Limit lane closures to off-peak travel periods. • Park construction vehicles off traveled roadways. Wet down or cover dirt hauled off-site. Wash or sweep access points daily. Encourage receipt of materials during non-peak traffic hours. f Sandbag construction sites for erosion control. The project should participate in any City adopted Transportation Demand Management (TDM) programs. 5-2 6.0 Conclusions This air quality analysis assesses the potential air quality impacts and necessary mitigation measures for the Ramona Expressway (SR-79) Expansion project. The project site is located along the Ramona Expressway (SR-79) segment between Sanderson Avenue and Lake Park Drive in the City of San Jacinto, as shown in Exhibit A. The site plan used for this analysis is presented in Exhibit B. The results of the analysis indicate that construction operation and dust from the project site will represent the principle sources of on-site air quality impacting the surrounding area. The following conclusions for the project are listed below: • The project-related short construction emissions along with the SCAQMD thresholds are shown in Table 7. Short-term construction impacts are below the SCAQMD thresholds and are considered less than significant. • The local significance emissions for construction along with the localized significance thresholds (LST) are indicated in Table 8. All LST's pollutants are below the thresholds after the implementation of the recommended mitigation measures. A detailed list of necessary air quality mitigation measures is presented in Section 5.0 Mitigation Recommendations. The air quality mitigation analysis and recommendations are intended to satisfy the South Coast Air Basin (SCAB) standards with respect to this project. 6-1 Exhibits j` Exhibit A Location Map C 0 v N L` y�" ,%' 4f \M1 m Qz` O t\., 1n H :Main rn it t.

GENERAL BIOLOGICAL RESOURCES ASSESSMENT AND MSHCP CONSISTENCY REPORT JANUARY 2010 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JAOINTO EXECUTIVE SUMMARY LSA Associates, Inc. (LSA) was retained by City of San Jacinto to prepare a biological resources assessment of an approximately 5-mile segment of Ramona Expressway in the City of San Jacinto, Riverside County,California.All road improvements are proposed within the existing roadway right-of- way. Items of importance to be addressed include the following: 1. Species of Concern a. Protected Species. i. Burrowing Owl. Focused survey is required. Burrowing owls are present in the Ramona Expressway right-of-way. Passive relocation is an available option during non-breeding season. ii. Nesting Birds.Pre-construction surveys for any potential active nests(including burrowing owl), if construction is planned to start during the breeding season (February 1 through August 31), including utility pole relocation. b. Rare and Listed Species. i. San Bernardino Kangaroo Rat and Los Angeles Pocket Mouse. Focused surveys are required in suitable habitat within the project area.The project is located within the MSHCP Mammal Survey Area.The survey area overlaps the project at Main Street/Lake Park Drive. 2. Western Riverside County Multiple Species Habitat Conservation Plan.The project is located within Criteria Cells 2893,3098,and 3099 of the Upper San Jacinto River/Bautista Creek Subunit 3 of the San Jacinto River Area Plan. The project is an existing road within the Criteria Area. The project is covered under the MSHCP Guidelines. The project will not disturb Conserved Land, Public/Quasi-Public Land, or Proposed Conservation Areas. The project's indirect effects to the existing MSHCP Reserve will be mitigated through compliance with MSHCP Section 6.1.4 Guidelines pertaining to the Urban/Wildlands Interface, Section 7.3.5: Planned Roads within the Criteria Area,Section 7.5.3:Construction Guidelines,and Appendix C:Best Management Practices. Within the Criteria Cells,the project will minimize any removal of vegetation remaining within the right-of-way that is outside the actual construction site and will avoid using grass-covered land for staging or parking that is outside of the right-of-way and within the proposed Conservation Area.

GENERAL BIOLOGICAL RESOURCES ASSESSMENT AND MSHCP CONSISTENCY REPORT JANUARY 2010 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JACINTO INTRODUCTION LSA Associates, Inc. (LSA) conducted a general biological resources assessment on the proposed Ramona Expressway Widening Project, an approximately 5-mile roadway in the City of San Jacinto, Riverside County, California. Specifically, the project site is Ramona Expressway, from Sanderson Avenue to East Main Street in the City of San Jacinto.Figure 1 shows the regional vicinity and project site in Sections 17, 20,29,and 32, Township 4 South,Range 1 West as shown on the U.S. Geological Survey(USGS)Lakeview, California and San Jacinto, California 7.5-minute series topographic maps. This report presents the results of a literature review and field survey. PROJECT DESCRIPTION Phase I: From Sanderson Avenue to State Street The project consists of pavement widening with new curb/gutter on both sides of centerline and concrete sidewalk on both sides.The widening will create three lanes of traffic in either direction,a center left-turn pocket or landscaped median, and minimal drainage improvements. The improvements will include adjustment and relocation of existing signal poles. Phase II: From State Street to Main Street/Lake Park Drive The project consists of pavement widening to provide for minimum of two lanes of traffic in each direction, one left-tum pocket or striped median including 5 to 8 feet of paved shoulder, and minimal drainage improvements.This project will also include adjustment and relocation of existing signal poles. BACKGROUND Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) The MSHCP provides for the assembly of a Conservation Area consisting of Core Areas and Linkages for the conservation of Covered Species. The Conservation Area is to be assembled from portions of the MSHCP Criteria Area,which consists of one-quarter-section sized Criteria Cells(i.e.,approximately 160 acres),each with specific criteria for the species conservation within that Cell.The MSHCP provides an incentive-based program, the Habitat Evaluation and Acquisition Negotiation Strategy (HANS), for adding land to the MSHCP Conservation Area.If it is determined that all or a portion of the property is needed for inclusion in the MSHCP Conservation Area,then various incentives may be available to the property owner in exchange for the conveyance of a property interest. The MSHCP requires focused surveys for certain plant, amphibian, and mammal species for projects located within designated plant and animal survey areas when potential suitable habitat is present. Surveys for listed riparian birds are required when suitable riparian habitat is present, and surveys for listed fairy shrimp species are required when vernal pools or other suitable habitat is present. Projects located in proximity to the MSHCP Conservation Areas may result in edge effects that will adversely affect biological resources within the MSHCP Conservation area.MSHCP Urban/Wildlands Interface Guidelines (MSHCP Section 6.1.4)are intended to reduce such indirect effects.

GENERAL BIOLOGICAL RESOURCES ASSESSMENT AND HSHOP CONSISTENCY REPORT JANUARY 2010 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JACINTO California Environmental Quality Act(CEQA) Adopted Habitat Conservation Plans.Section 10(a)(2)(A)of the 1973 Federal Endangered Species Act (FESA) requires the preparation of a habitat conservation plan for incidental take of threatened or endangered species when there is no federal agency involvement in a project. The MSHCP and the Stephens' Kangaroo Rat Habitat Conservation Plan(SKR HCP)are the principal habitat conservation plans in western Riverside County. Threatened and Endangered Species Listed Species.The U.S.Fish and Wildlife Service(USFWS)can designate critical habitat that identifies specific areas,both occupied and unoccupied,that are essential to the conservation of a listed species.Critical habitat areas may require special management considerations or protections if the project involves a federal agency. Other Special Interest Species.Other special interest species have the potential to occur on the proposed project site.The California Department of Fish and Game(CDFG),USFWS,local agencies,and special interest groups, such as the California Native Plant Society (CNPS),maintain lists of species that they consider to be in need of monitoring.Legal protection for special interest species varies widely,from the comprehensive protection extended to listed threatened/endangered species to no legal status at present. Protected Bird Species.Most bird species are protected under the Migratory Bird Treaty Act(MBTA) and under Sections 3503,3503.5, and 3800 of California Fish and Game Code. It is unlawful to take, possess,or needlessly destroy any bird of prey or the nests or eggs of any kind of bird species except as otherwise provided in the California Fish and Game Codes and regulations.Disturbance of any active bird nest during the breeding season is prohibited. Disturbances at active nesting territories should be avoided during the nesting season; typically,February 1 through August 31. Wildlife Movement,Corridors,and Nursery Sites.Wildlife movement includes seasonal movement along migratory corridors, as well as daily movements for foraging. Migratory corridors may include corridors for unobstructed movement of deer, riparian corridors providing cover for migrating birds, routes between breeding waters and upland habitat for amphibians, and between roosting and feeding areas for birds. Natural Communities of Interest.Riparian habitats,oak woodlands, and vernal pools are among the natural communities of interest to the CDFG. Coastal sage scrub is not considered a sensitive natural community unless it is occupied by California gnatcatcher(Polioptila californica). WetlandsNernal Pools. Wetlands, as defined by the U.S. Army Corps of Engineers (ACOE), must possess hydrophytic vegetation,hydric soils,and wetland hydrology.In order to be considered a vernal pool under the MSHCP, a depression must also meet these three wetland criteria. RATLK0901\GBA rpt.dDD(9/23/2010) 4 LSA ASSOCIATES. INO. GENERAL BIOLOGICAL RESOURCES ASSESSMENT AND MSNCP CONSISTENCY REPORT JANUARY 2010 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JACINTO Local Policies and Ordinances Protecting Biological Resources.City and County General Plans and development ordinances may include regulations or policies governing biological resources.For example, policies may include tree preservation,locally designated species survey areas,local species of interest, and significant ecological areas. Direct Effects. Direct effects are impacts that occur at the same time and in the location of the actual construction work.The associated impacts with construction activities have the potential to result in the destruction,disturbance,and removal of plants,animals,watercourses, and natural communities. Indirect Effects.Indirect effects are impacts caused by the project action but are later in time or farther in distance from the actual construction work.Indirect effects include growth inducement,changes in land use patterns, increased human intrusion, population growth, noise, and impacts to air quality, wind movements,water quality,hydrology,plant communities,wildlife movement,and regional ecosystems. Cumulative Effects. Cumulative impacts refer to incremental effects of an individual project when viewed in connection with the effects of past projects, current projects, and probable future projects. Cumulative impact assessments are difficult because the consequences triggered by the impacts affect resources that function as part of a larger complex natural system, and because the effects may be removed in time and space and may not be apparent when only considering the local and short-term direct impacts. ACOE and CDFG Jurisdictional Areas The ACOE,under Section 404 of the Federal Clean Water Act(CWA),regulates discharges of dredged or fill material into"waters of the United States."These waters include wetlands and non-wetland areas including ephemeral drainage courses.The ACOE typically regulates as non-wetland waters of the U.S. any body of water displaying an "ordinary high water mark" (OHWM). In order to be considered a jurisdictional wetland under Section 404 of the CWA, an area must possess hydrophytic vegetation, hydric soils, and wetland hydrology. The CDFG,under Sections 1600 et seq.of the California Fish and Game Code,regulates alterations to lakes,rivers,and streams.A stream is defined by the presence of a channel bed and banks,and at least an ephemeral flow of water. The Regional Water Quality Control Board(RWQCB)is responsible for the administration of Section 401 of the CWA, through water quality certification of any activity that may result in a discharge to jurisdictional waters of the U.S. The RWQCB may also regulate discharges to "waters of the State," including wetlands, under the California Porter-Cologne Water Quality Control Act.

GENERAL BIOLOGICAL RESOURCES ASSEBSMENT AND MSHCP CONSISTENCY REPORT JANUARY 2010 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JACINTO METHODS Literature Search A literature review was conducted to determine the existence or potential occurrence of sensitive plant and animal species on the proposed project site or in the vicinity.Database records for the Lakeview and San Jacinto, California USGS 7.5-minute quadrangles were reviewed on January 14, 2010, using the CDFG Rarefind 2 California Natural Diversity Data Base (CNDDB, 2006) and the CNPS Electronic Inventory of Rare and Endangered Vascular Plants of California(2006). A current aerial photograph (Eagle Aerial 2004) was also reviewed. Maps of USFWS-designated critical habitat were used to determine the location of critical habitats relative to the project site. General Biological Survey A field survey was conducted on December 30,2009, by LSA Associate/Biologist Maria Lum.Notes were made on general site conditions, vegetation,potential ACOE and CDFG jurisdictional areas, and suitability of habitat for various sensitive elements.All plant and animal species observed or otherwise detected during this field survey were noted. Appendix A summarizes the occurrence probability for sensitive plant and animal species in the proposed project area. ENVIRONMENTAL SETTING This section discusses the existing site conditions,including topography,soils,and vegetation.Previously referenced Figure 1 shows the regional and local project location. Existing Land Use Land use along Ramona Expressway and Esplanade Avenue includes adjoining roads and infrastructure, commercial shopping areas,rural residences,newly developed single-family homes,agricultural lands. All proposed work will be conducted within the existing right-of-way of Sanderson Avenue. Refer to Figure 2 for map of existing land use and vegetation types on undeveloped land.Approximately 2 miles of the project are in between agricultural fields,2 miles are adjacent to dense housing,college campus, and commercial areas,and 1 mile is next to the San Jacinto River west levee.The land within the right-of- way is well maintained by grading or mowing. The ground is landscaped,bare ground, or covered by annual grasses. Topography and Soils The Ramona Expressway Widening Project ranges in an elevation from approximately 1,460 to 1,515 feet above mean sea level(amsl).The roadway and adjacent land are level through the project area.Table A lists the soil units that are present within the project area, as mapped by the Soil Conservation Service (Knecht 1980).Soils in the project area have high sand content,water table within three to four feet,and the majority has some degree of saline-alkali chemistry. Figure 3 provides illustration of the soil types within the project area. R:\TLK0901\GBA rpt.doc(9/23/2010) 6 LSA ASSOCIATES. INC.

GENERAL BIOLOGICAL RESOURCES ASSESSMENT AND MSHOP CONSISTENCY REPORT JANUARY 5010 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF BAN JACINTO The project site is not within the MSHCP Narrow Endemic Plant Species Survey Area(NEPSSA) or Criteria Area Species Survey Area (CASSA); therefore, even though soils known to support narrow endemics and criteria area plant species occur in the project area, surveys are not required. Also, development and the long-term agricultural land use in the project area has eliminated the necessary growing conditions to support the species of interest. Vegetation Dominant plant cover present within the Ramona Expressway right-of-way includes non-native grasslands, ruderal, and manicured landscaped. Vegetation identified within the project site included Bermuda grass (Cynodon dactylon), Palmer's pigweed (Amaranthus palmeri), common sunflower (Helianthus annuus),common fiddleneck(Amsinckia menziesii),shortpod mustard(Hirschfeldia incana), London rocket(Sisymbrium Trio),Russian thistle(Salsola tragus),cheeseweed(Malva parviora),and Mexican sprangletop (Leptochloa uninervia). Landscaping includes London planetree (Platanus acerifolia). Wildlife Wildlife observed or other presence noted(scat, tracks, and burrows)during the field survey included red-tailed hawk(Buteo jamaicensis), common raven (Corvus corax), western scrub jay (Aphelocoma californica), lesser gold finch (Carduelis psaltria), and numerous migratory waterfowl observed in adjacent detention basins. A western burrowing owl (Athene cunicularia) is present within the project area. California ground squirrels (Sperniophilus beecheyi) and pocket gophers (Thomomys bottae)are abundant in the right-of-way.

GENERAL BIOLOGICAL RESOURCES ASSESSMENT AND MSHOP CONSISTENCY REPORT JANUARY 2610 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JACINTO Urban[Wildlands Interface Requirements.The project is adjacent to an existing MSHCP Conservation Area (San Jacinto River); therefore, the guidelines provided in MSHCP Section 6.1.4 regarding urban/wildlands interface are applicable to this project. Overall Consistency with Reserve Assembly Criteria.The project is covered under the MSHCP as an existing road improvement(widening),per Section 7.3.5:Planned Roads within the Criteria Area of the MSHCP.The project is adjacent to the MSHCP Conservation Area;therefore,it will be consistent with the conservation objectives through compliance with Section 7.5.3: Construction Guidelines and Appendix C:Best Management Practices. Within the Criteria Cells,the project will minimize any removal of vegetation remaining within the right- of-way that is outside the actual construction site and will avoid using grass-covered land for staging or parking that is outside of the right-of-way and within the proposed Conservation Area. Riparian/Riverine and Vernal Pool Requirements The Ramona Expressway Widening Project site lies entirely within the existing right-of-way. No riparian/riverine or vernal pool habitat is located within project site. No suitable habitat is present for sensitive riparian bird species. Therefore, no surveys for such species will be required. There are no vernal pools or similar habitats present on the project site;therefore,no surveys for listed fairy shrimp species will be required. Burrowing Owl Survey Area The project is located within the MSHCP designated survey area and suitable habitat for the burrowing owl is present within the project area. A burrowing owl was observed during the habitat suitability assessment survey on December 30, 2009. A focused burrowing owl and a pre-construction clearance surveys are required.Refer to previously referenced Figure 4 for map of the MSHCP survey areas. Mammal Survey Area The project is located within the MSHCP survey area for two fossorial mammals: the San Bernardino kangaroo rat(Dipodomys merriami parvus),federally endangered,and the Los Angeles pocket mouse (Perognathus longimembris brevinasus),California Species of Concern.Both species are known to occur in the San Jacinto River and adjacent alluvial terraces.Surveys for the San Bernardino kangaroo rat and Los Angeles pocket mouse are necessary. CEQA ISSUES Habitat Conservation Plans The project site is within the MSHCP area. The project site is also within the Stephens' Kangaroo Rat Habitat Conservation Plan (SKR HCP) fee area. Although no Stephens' kangaroo rat (Dipodomys stephensi)surveys are required,payment of a fee is necessary. RATLK09MGBA rpt.doc(9/2 312 0 1 0) 19 LBA ASSOCIATES, INC. GENERAL BIOLOGICAL RESOURCES ASSESSMENT AND MSHCP CONSISTENCY REPORT JANUARY 1010 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF BAN JACINTO Threatened and Endangered Species The project site is not located within a USFW S designated critical habitat.The San Bernardino kangaroo rat final critical habitat(USFWS 2008)begins at Main Street Bridge and extends upstream to the national forest boundary in the City of Hemet. The project is located in an MSHCP Species Survey Area. The project is required to conduct focused surveys for the San Bernardino kangaroo rat and the Los Angeles pocket mouse to determine presence or absence of these species within the project area. Other Special Interest Species The special interest species listed in Table B are known to occur in general project vicinity or are listed in the NDDB and CNPS data records, but are not covered under the MSHCP, or are not adequately conserved by the MSHCP at this time.Eight species have a low probability to occur on the project site. The project site contains fragmented,highly disturbed,and poor quality habitat for any of these species; therefore, any impacts to these species by the project would not be considered significant. The two species listed as threatened or endangered under state or federal law are have no potential to be present in the project area. The additional surveys or conservation measures are not required for these species.

MSHCP:Western Riverside County MSHCP Status S Species is adequately conserved under the MSHCP,but surveys are required within indicated habitats and/or survey areas. P Species is covered but not considered adequately conserved pending completion of MSHCP specified requirements. Protected Bird Species Trees taller than 15 feet on or adjacent to the project site may provide roosting and nesting habitat for raptors such as hawks and owls,ravens,or other birds and bats.Trees,shrubs,and other vegetation may provide nest sites for smaller birds. The exact time of year when avian species nest can vary greatly among species within the same geographic area. Generally, nesting season ranges from February 1 to August 31.If tree removal is to take place during the nesting season,then pre-construction nest survey(s) are required to ensure that no active nests are on or adjacent to the project site.The last survey day is to be conducted within three days prior to the start of work. Wildlife Movement,Corridors,and Nursery Sites Development adjacent to the project area is concentrated in the central segment between Potter Road and Alessandro Avenue.The northern and southern segments of the project site remain mostly surrounded by agricultural and vacant lands. The project does not intersect any functional corridors. The project area does not have any nursery sites.Areas lacking residential and commercial development are still open to wildlife movement and seed dispersal across the Ramona Expressway but there are no areas with functional live-in habitat or temporary shelter or cover. The project site is adjacent to the San Jacinto River,a designated MSHCP Core/Linkage Area.This is an important wildlife movement corridor/linkage and means of dispersal for plants,organic matter,sediment, and seasonal water source.It provides live-in habitat for San Bernardino kangaroo rat.The project will affect this functional wildlife movement corridor, but will be required to ensure compliance with the MSHCP to avoid and minimize indirect effects during construction. Refer to the MSHCP Compliance section above for MSHCP consistency requirements. R:iTLK09011GBA rpt.doc(9/23/2010) 24 LSA ASSOCIATES. INC. GENERAL BIOLOGICAL RESOURCES ASSESSMENT AND MSHUP CONSISTENCY REPORT JANUARY 2010 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JACINTO Natural Communities of Interest No plant communities of special interest due to known associations with rare or listed plant and animal species are present within the project site;therefore,no additional mitigation measures are required. There are soil types mapped and found on the project site that indicate a potential for rare or listed plants to occur in the project area. Nevertheless, under the MSHCP, the project is not required to conduct focused plant surveys, since the project is not within a Narrow Endemic Plant Species Survey Area (NEPSSA)or Criteria Area Species Survey Area(CASSA).Any potential impacts to plant species found outside the survey areas are mitigated through participation in the MSHCP. WetlandsNernal Pools The MSHCP does not designate any survey areas or potential concern for vernal pools in the project area. No surveys or mitigation is required beyond participation in the MSHCP. Local Policies and Ordinances Protecting Biological Resources There are no local ordinances applicable to biological resources except for code provisions related to the MSHCP mitigation fee. Indirect Effects The project area is surrounded by existing and ongoing residential development.It is located within an MSHCP Criteria Area and if the project area is limited to the north side of Main Street/Lake Park Drive, then the project will not be in a proposed acquisition area for the MSHCP Reserve to add land to the San Jacinto River Core/Linkage Area.Therefore,only MSHCP Guidelines for Urban/Wildlands Interface are applicable to this project. Cumulative Effects Cumulative impacts typically include habitat fragmentation, increased edge effects, reduced habitat quality,and increased wildlife mortality.The MSHCP provides a comprehensive approach to the regional conservation of these habitats and,as a regional plan,serves to provide mitigation for cumulative impacts to covered species. Project compliance and consistency with the MSHCP ensure that any cumulative impacts to covered species are effectively mitigated. Special interest species that are not covered by the MSHCP also benefit from the surveys,conservation, and other measures of the MSHCP because they occupy many of the same habitats. Therefore,cumulative effects as a result of the proposed"Covered" project are mitigated through participation in the MSHCP. ACOE AND CDFG JURISDICTIONAL AREAS There is a concrete drainage feature on the west side of Ramona Expressway between Potter Road and Record Road that is not considered jurisdictional under CWA Sections 401 or 404, and not subject to R:\TLK0901\GBA rpt.doc(9)23/2010) 25 LEA ASSOCIATES. INC. GENERAL BIOLOGICAL RESOURCES ASSESSMENT AND MEHOP CONSISTENCY REPORT JANVARY 2010 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JACINTO California Fish and Game Code Sections 1600 et seq.The concrete channel is constructed as part of the stormwater infrastructure.Runoff flows northwest to a detention basin and is contained in the adjacent residential housing tract. A waters of the U.S./wetland delineation survey and report is not required. No roadside ditches or storm drains are associated with a natural drainage feature or streambed. Thus, there are no drainages subject to ACOE jurisdiction.There are no artificial channels or ditches that have acquired characteristics or function of a natural streambed.Therefore,there are no CDFG jurisdictional sites within the project area. CONCLUSIONS The proposed project site encompasses the intersections of Ramona Expressway and Sanderson Avenue, south to the intersection of Ramona Expressway and Main Street/Lake Park Drive. The project area is surrounded by mix of agriculture,rural residences, farm ponds, newly constructed residential housing tracts, and dense residential, institutional, and commercial land development. Vegetation within the project site is limited to bladed or disked road shoulder,landscaping,and disturbed non-native grasslands. The project site is located within and adjacent to four Cells in the MSHCP San Jacinto Valley Area Plan. The project will not affect any areas important to the creation of the MSHCP Reserve. The project is limited to previously disturbed or developed areas and the existing right-of-way. The project site is adjacent to the San Jacinto River Existing Linkage Area. Even though wildlife movement would not be impeded by the project,the project will incorporate construction best management practices to minimize construction impacts to the existing Conservation Land. The project site is located within the MSHCP Burrowing Owl Survey Area. Suitable habitat for the burrowing owl is present within and adjacent to the project site; therefore, focused surveys (presence/absence)for the burrowing owl are required. The project site contains several trees suitable for avian nesting.If tree removal is to take place during the nesting season,generally February 1 through August 31,pre-construction nest survey(s)are required to ensure that no active nests are on or adjacent to the project site. The last survey day is to be conducted within three days prior to the start of work. The project is located with an MSHCP Mammal Survey Area. Focused surveys for San Bernardino kangaroo rat and Los Angeles pocket mouse are required prior to construction. There are no drainage features in the project area subject to ACOE and/or CDFG jurisdiction;therefore,a jurisdictional delineation is not needed.Standard water quality control practices for construction projects are necessary.

CULTURAL RESOURCES ASSESSMENT APRIL 0011 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JACINTO MANAGEMENT SUMMARY LSA Associates,Inc. (LSA) was retained by the City of San Jacinto to conduct a cultural resources assessment of the proposed Ramona Expressway Widening Project(project)located in the City of San Jacinto,within the County of Riverside, California. The project includes the section of Ramona Expressway between Sanderson Avenue and Main Street.It is approximately five miles in length and comprises approximately 92 acres. The cultural resources assessment was completed pursuant to the California Environmental Quality Act(CEQA). A cultural resources records search and a field survey were conducted for the project on October 5 and October 14 and 15, 2010,respectively.No cultural resources have been previously documented within the project boundaries and none were identified during the field survey. Due to the negative results of both the records search and the field survey,LSA has determined the sensitivity of the project area is low and archaeological monitoring is not required.In the event of identification of previously undocumented cultural resources during earthmoving activities within the project boundaries,it is recommended that a qualified archaeologist shall be retained to assess the nature and significance of the find,diverting construction excavation if necessary. If human remains are encountered, State Health and Safety Code Section 7050.5 states that no further disturbance shall occur until the County Coroner has made a determination of origin and disposition pursuant to Public Resources Code Section 5097.98. The County Coroner must be notified of the find immediately. If the remains are determined to be prehistoric,the Coroner will notify the Native American Heritage Commission(NAHC),which will determine and notify a Most Likely Descendant (MLD). With the permission of the landowner or his/her authorized representative,the MLD may inspect the site of the discovery. The MLD shall complete the inspection within 48 hours of notification by the NAHC.The MLD may recommend scientific removal and nondestructive analysis of human remains and items associated with Native American burials. Both of these measures regarding unanticipated finds of cultural material and/or human remains should be added to the construction notes on the engineering drawings so field personnel and others are aware of this possibility and are informed as to what to do in the event this occurs.

INC. CULTURAL RESOURCES ASSESSMENT APRIL 2011 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JACINTO INTRODUCTION LSA was retained by the City of San Jacinto to conduct a cultural resources assessment of the proposed project(Figure 1). This assessment addresses the requirements of CEQA(as amended January 1, 2010): Public Resources Code (PRC),Division 13 (Environmental Quality), Chapter 2.6 Section 21083.2 (Archaeological Resources) and Section 21084.1 (Historical Resources); and the Guidelines for CEQA(as amended December 15,2009), California Code of Regulations(CCR)Title 14, Chapter 3,Article 5 Section 15064.5 (Determining the Significance of Impacts on Historical and Unique Archaeological Resources). Phase 1 of the project proposes to widen Ramona Expressway from two lanes to six lanes between Sanderson Avenue and Eagle Road, and Phase 2 of the project proposes to widen Ramona Expressway from 2 lanes to 4 lanes from Eagle Road to Main Street. The project is situated in the alluvial valley/plain of the San Jacinto Valley, south of the San Jacinto Mountains and east of the Lakeview Mountains The majority of the project is situated on the United States Geological Survey(USGS)San Jacinto, California 7.5-minute topographical quadrangle map (1953/1978)in unsectioned lands in Township 4 South,Range I West.A small portion of the project is situated on the eastern edge of the USGS Lakeview, California 7.5-minute topographical quadrangle map(1967/1979) in Section 17,Township 4 South,Range 1 West. NATURAL SETTING The project area is located within the City of San Jacinto in the western portion of west-central Riverside County. The City of San Jacinto, and this portion of the Ramona Expressway, is bounded on the north by the Badlands, on the northeast by the foothills of the San Jacinto Mountains, and on the south by the City of Hemet. The portion of the Ramona Expressway under study is south of the San Jacinto River. The project is located within the alluvial plain known as the San Jacinto Valley. An LSA biologist conducted a field survey for this project in December 2009 and the following vegetation and wildlife information comes from that study. Vegetation Dominant plant cover present within the Ramona Expressway right-of-way(ROW)includes nonnative grasslands,ruderal, and manicured landscape. Vegetation identified within the project site included Bermuda grass(Cynodon dactylon),Palmer's pigweed(Anzaranthus pahneri), common sunflower(Helianthus annuus), common fiddleneck(Anzsinckia menziesii), shortpod mustard (Hirschfeldia incana),London rocket(Sisymbriunz Trio),Russian thistle (Salsola h-agus),cheeseweed (Malva parviora), and Mexican sprangletop(Leptochloa uninervia).Landscaping includes London planetree(Platanus acerifolia). Wildlife Wildlife observed or other presence noted(scat, tracks, and burrows)included red-tailed hawk(Buteo janzaicensis), common raven(Corvus corax), western scrub jay(Aphelocorrza californica), lesser gold RATLK1002_Ramona Exp\CultumlTulmral Resources Assessment Reportlramona expressway TLK1002 4-5-1 Ldoc(415/2011) 1 'S4cQ��" Ilk1 �¢ J si 1�� !'�,�P�`\I� �%`(,y y 'St' 1� :n'�t , (I rl. rn•,,� W...�\. • L''I ,. r�TO * r+r� ,, rj �'.`�`'`` �%o�a-��i �'(' r�/,i E.�b.len+dr't - �e� .• \lam\. ��/�ni-a' i ' � �=. ... . 1.. 9R��C_' RIVER p` AGI.'E r ;10 3 �.R�` �E:� I�t`'• ��h'laf �f r � It i�l (rlYl ' 0 Ile � I I 1�1, 11aa, _ tli � 1 P , Project Location F � wo,uMr. 'IW— •.•r.d L.. .. ..

CULTURAL RESOURCES ASSESSMENT APRIL 2011 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JACINTO finch(Carduelis psaltria), and numerous migratory waterfowl observed in adjacent detention basins. A western burrowing owl(Athene cunicularia) is present within the project area. California ground squirrels(Spermophilus beecheyi) and pocket gophers(Thonsomys bottae)are abundant in the ROW. The natural biology of the project has been disrupted by human development,including farming, agricultural operations, and development, especially the existing Ramona Expressway. Geology The project area is situated on young active wash deposits(Qyva; Early Pleistocene—latest Holocene; Morton 2004;Morton and Matti 2001;Rogers 1965), which sit as terraces above young axial-valley deposits(Qw,late Holocene;Morton 2004)of the San Jacinto River. The soils and surficial sediments of the project area have only been disturbed by farming activities, and they have potential for preservation of intact buried cultural resources. Hydrology The project is located in the San Jacinto Valley Hydrologic Unit, which includes the San Jacinto Groundwater Basin. The San Jacinto Valley unit is part of the Santa Ana River drainage. The San Jacinto Valley is subject to a semi-arid climate,with dry,hot summers and moderate winters. Rainfall averages 10-18 inches per year(State of California 2003).Precipitation usually occurs in the form of winter rain,with sporadic showers in summer. The San Jacinto River runs in a nortbwest-southeast direction at the toe of the San Jacinto Mountains and roughly parallels the project.In its current configuration,the river is to the north of the project area at distances varying from approximately 0.25-1 mile. CULTURAL SETTING Prehistory Of the many chronological sequences proposed for Southern California,two primary regional syntheses are commonly used in the archaeological literature. The first, advanced by Wallace (1955), defines four cultural horizons,each with characteristic local variations: Early Man Horizon,Milling Stone,Intermediate,and Late Prehistoric. Employing a more ecological approach, Warren(1986) defined five periods in Southern California prehistory: Lake Mojave,Pinto, Gypsum, Saratoga Springs,and Protohistoric. Warren viewed cultural continuity and change in terms of various significant environmental shifts,defining the cultural ecological approach for archaeological research of the California deserts and coast. Many changes in settlement patterns and subsistence focus are viewed as cultural adaptations to a changing environment,beginning with the gradual environmental warming in the late Pleistocene,the desiccation of the desert lakes during the early Holocene,the short return to pluvial conditions during the middle Holocene, and the general warming and drying trend,with periodic reversals,that continues to this day(Warren 1986).

CULTURAL RESOURCES ASSESSMENT APRIL 2011 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JACINTO Ethnography The project area is within the traditional cultural territory of the Cahuilla(Bean 1978). Like other Native American groups in Southern California,the Cabuilla were semi-nomadic hunter-gatherers who subsisted by exploitation of seasonably available plant and animal resources and were first encountered by the Spanish missionaries in the late 18d'century. The first written accounts of the Cahuilla are attributed to mission fathers. Subsequent ethnograpbies have been written by Barrows (1900),Kroeber(1925),Hooper(1920) Strong(1929),Bean (1972),and many others. The territory of the Cahuilla ranges from the area near the Salton Sea up into the San Bernardino Mountains and San Gorgonio Pass(Bean 1978;James 1960;Kroeber 1925;Kroeber and Hooper 1978). The Cahuilla are generally divided into three groups: Desert Cahuilla,Mountain Cahuilla, and Western(or Pass)Cahuilla(Kroeber 1925). The term Western Cahuilla is preferred over Pass Cahuilla because this group is not confined to the San Gorgonio Pass area(James 1960). The distinctions are believed to be primarily geographic, although linguistic and cultural differences may have existed to varying degrees (Strong 1972). Cahuilla territory lies within the geographic center of Southern California; and the Cocopa-Maricopa Trail,a major prehistoric trade route,ran through it (Bean 1978). Cahuilla villages generally were located near water sources such as creeks or springs within canyons or near alluvial fans. Cahuilla villages were made of groups of related individuals,generally from a single lineage,and the territory around the village was owned by the villagers(Bean 1978b). Like other Native American groups in Southern California,the Cahuilla were semi-nomadic peoples leaving their villages and utilizing temporary campsites to exploit seasonably available plant and animal resources(James 1960). Cahuilla subsistence was based primarily on acorns,honey mesquite, screw beans,pinon nuts, and cactus fruit, supplemented by a variety of wild fruits and berries,tubers,roots,and greens (Kroeber 1925;Heizer and Elsasser 1980). A list of Cahuilla plant foods is provided by Barrows (1900), who undertook fieldwork prior to 1900.Hunting deer,rabbit,antelope,bighorn sheep,reptiles, small rodents, quail, doves,ducks, and reptiles by means of bows,throwing sticks,traps,and communal drives is documented(James 1960). Artifacts common to the Cahuilla include coiled pottery (often incised and painted),baskets,manos, metates,mortars,pestles, steatite arrow shaft straighteners, mesquite or willow bows and arrows, wooden throwing sticks, charm stones,bull-roarers, and small bifacially worked stone points (Kroeber 1925).Marine shells,including Olivella sp.beads, were used for money and are often associated with cremations. Cahuilla buildings were generally dome-shaped or rectangular. Size depended upon the family's needs.The chief s house was the largest and supported many activities. Typically, it would be located next to a ceremonial house where rituals,curing ceremonies, and recreational activities took place. Several granaries would be built within village boundaries.A communal men's sweathouse would also be found in a Cahuilla village(Bean 1978). Today,several reservations are identified as being Cahuilla and include:Agua Caliente,Augustine, Cahuilla, Los Coyotes, Morongo,Ramona, Santa Rosa, and.Torres Martinez.

CULTURAL RESOURCES ASSESSMENT APRIL 2011 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JACINTO History The historic period in Riverside County began when Lieutenant Pedro Fages,governor of San Diego, crossed through the San Jacinto Valley in 1772. During the Mission Period(1769-1833),Riverside County proved to be too far inland to include any missions or asistencias within its limits. The Asistencia de Mission San Gabriel, located in what is now Redlands,was built between 1819 and 1820(Harley 1988). Gaspar PortoWs expedition in California established Mission San Luis Rey in 1798,which claimed a large part of southwestern Riverside County for livestock grazing. In 1821,Mexico successfully overthrew Spanish rule and the missions lost the financial and political support required to keep them going.The Mexican Secularization Act of 1833 reorganized the missions as parish churches with no land holdings or neophytes. The Mexican government supervised the transition of missionary lands into the hands of private citizens. In 1842,Jose Antonio Estudillo was granted more than 35,000 acres by Governor Alvarado for his services as Major Domo of Mission San Luis Rey during its secularization by the Spanish. Until the Gold Rush of 1849, livestock and horticulture dominated the economics of California(Ingersoll 1904; Beattie 1925; Beattie and Beattie 1951). As travel along the Santa Fe Trail brought more settlers, the pattern of settlement developed along the Santa Ana and San Jacinto waterways. In 1858,the first stage of the Butterfield Overland Mail passed through Temecula in southwestern Riverside County.The Southern Pacific Railroad completed its line from Los Angeles through San Gorgonio Pass in 1876,creating a period of agricultural and land development,ultimately resulting in the establishment of Riverside County from a portion of San Diego County in 1893. The community of San Jacinto was established in the 1850s on a portion of the San Jacinto Rancho (granted to Jose Antonio Estudillo in 1842).By 1870,it was well established with a post office, store, and 23 residences. Due to a homicide by the leading businessman of the community(H.T. Hewitt), and ensuing litigation, the settlement was in decline by the early 1880s. In 1883,the community was moved north to its present location by the San Jacinto Land Association, which purchased land from the Estudillo family and laid out a new town site. The post office was relocated shortly thereafter,and the original settlement became known as Old Town, South San Jacinto and finally, Bowers. In 1886, the population numbered in excess of 1,500. The San Jacinto Valley Railway branch line from Perris was completed by 1888. San Jacinto was incorporated as a city that same year, and when Riverside County was formed,the community was designated 1 of the 12 original judicial townships(Gunther 1984). One historic source indicates that at one time, San Jacinto was one of the best alfalfa districts in the world(Brown 1922). Alfalfa farming led to dairy cattle ranching,a practice still prevalent today in parts of the San Jacinto Valley. Today, San Jacinto has grown into a suburban city but still exhibits its rural roots. The population of San Jacinto in 2010 was 36,933 (City of San Jacinto website 2010).

CULTURAL RESOURCES ASSESSMENT APRIL 0011* RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JACINTO METHODS Research On October 5,2010, LSA Cultural Resources Analyst Britt Wilson conducted a records search at the Eastern Information Center(EIC)of the California Historical Resources Information System (CHRIS), located at the University of California,Riverside. Cultural resource maps at the EIC were checked for previously recorded prehistoric and historic resources within and adjacent to the project area.Also examined were the National Register of Historic Places (National Register) Index,Office of Historic Preservation Directory of Properties,historic USGS topographic maps,and General Land Office(GLO)maps. Native American Scoping On September 23,2010, LSA contacted the State of California Native American Heritage Commission(NAHC)to request a search of the Sacred Lands File (SLF),which includes Traditional Cultural Properties(TCPs), sacred sites, and any other Native American cultural resources that may be affected by this project.Also requested was a list of Tribes, groups, and individuals with ancestral ties to the vicinity of the project area. The NAHC responded on September 30,2010,and reported that the SLF search indicated the presence of Native American cultural resources within a 0.5-mile radius of the proposed project area. The NAHC also provided a list of Native American contacts that may have information regarding whether the project may harm a cultural resource and recommended that contact be made with the persons on the list. Consequently,LSA prepared a letter describing the project and seeking input. The letters were sent out via certified mail on October 8, 2010,to the 13 parties on the NAHC list.As of December 21,2010,five responses have been received.Four of the responses had no particular concerns or requests; they were primarily acknowledgements of the project. The fifth response came from the Soboba Band of Luiseno Indians in a letter dated October 18, 2010. The response letter from Soboba requested the following: • Consultation with the project Developer and Land Owner. Transfer of information to the Soboba Band of Luiseno Indians regarding the progress of this project as soon as the new developments occur. • Soboba Band of Luiseno Indians continues to act as a consulting tribal entity for this project. • Native American monitors from the Soboba Band of Luiseno Indians to be present during any ground-disturbing activities. • Certain procedures be followed concerning artifacts and human remains. This last request concerns the transfer of all cultural artifacts to the Soboba Tribe and spells out procedures for addressing human remains. Although some of the information that the Soboba Tribe provided references State law,most of the concerns are regarding consultation and/or agreement between Soboba and the City. (See Appendix A for a complete record of the Native American Scoping and responses for this project.) &\TLK1002_Ramona ExplCulttual\Cultural Resources Assessment Report7amona expressway 7LK1002 4-5-1 Ldac(415/2011) 6 LSA ASSOCIATES, INC. CULTURAL RESOURCES ASSESSMENT APEIL 2111 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JACINTO Field Survey LSA Archaeologist Riordan Goodwin conducted the pedestrian survey for the project on October 14 and 15,2010. Mr. Goodwin walked transects spaced at approximately 15-meter intervals until the entire project area had been surveyed. The survey was limited to project ROW areas only. RESULTS Research Data from the EIC indicate that no resources have been recorded within the project boundaries but two historic houses have been recorded adjacent to the project(Appendix B). Sixty-six cultural resource studies have been conducted within a 1-mile radius of the project. Of these, 14 included the project boundaries or portions thereof or are adjacent to the project.The EIC has site records on file for 45 historical resources and 3 prehistoric resources that are within the 1-mile records search radius but are outside the project boundaries. The historical resources consist of irrigation wells; water tanks; a historic road; residential/ranching buildings,structures,and objects; a silo tower; 60 houses (a single site record)within the San Jacinto downtown historic core area; and a refuse dump.The prehistoric resources consist of the prehistoric village oflvah (CA-R1V-124, approximately 0.5 mile west of the project alignment), a traditional plant gathering place(33-017364,approximately 1 mile northeast of the project alignment), and the site of Soboba Hot Springs (CA-RIV-125, 1 mile east of the project area). GLO maps identify the land in the project area as"Part of Rancho San Jacinto Viejo"(GLO 1867)or "Part of Rancho San Jacinto Estudillo" (GLO 1885, 1900).This was the Mexican land grant of some 35,000 acres granted to Jose Antonio Estudillo in 1842(see History Section). These same GLO maps do not indicate any structures in the project boundaries but today's Ramona Expressway may cross or parallel an irrigation ditch shown on the 1900 map.Today's Ramona Expressway also crosses the "Beaumont and San Jacinto Road" (GLO 1885, 1900). This road appears to be today's State Street/State Highway 79. Today's Ramona Expressway also crosses a road that led to Soboba Hot Springs (GLO 1867, 1885, 1900).No remnants of that road are visible today within the project boundaries,having been destroyed by agricultural fields and the San Jacinto River channel. Historic USGS topographical maps indicate structures along a portion of a road that became part of today's Ramona Expressway(USGS 1901, 1953.);however,there are no recorded sites in the project boundary in that area, and the subsequent field survey failed to indicate the presence of these structures within the project boundaries. Without specific engineering maps of these structures in comparison to conditions today,it is difficult to determine whether these structures are within the project boundaries. It is likely that they were destroyed through agricultural development or the construction and widening of Ramona Expressway during the ensuing years. A review of the National Register did not indicate the presence of any National Register-eligible properties within the project boundaries.A review of the State of California State Historic Preservation Office's California Historical Resources did not indicate the presence of a California Landmark or any property on the California Register of Historical Resources within the project boundaries.

CULTURAL RESOURCES ASSESSMENT APRIL 2011 RAMONA EXPRESSWAY WIDENING PROJECT CITY OF SAN JACINTO Field Survey No cultural resources were identified within the project boundaries during the field survey. Ground visibility varied from 0-100 percent. Landscaped parkways,heavy brush, or crops obscured parts of the project area.Visibility averaged approximately 70 percent.As shown in the Figures 2 and 3,the project area is highly disturbed due to farming,irrigation development, and residential/ranching operations over the years,and especially the development of Ramona Expressway. RECOMMENDATIONS Due to the negative results of both the records search and the field survey,LSA has determined the sensitivity of the project area is low,no further cultural resources studies are warranted,and archaeological monitoring is not required under CEQA. In the event of unanticipated archaeological discovery, LSA recommends that a qualified archaeologist be retained to assess the nature and significance of the find, divert construction excavation,if necessary, and prepare a Treatment Plan,if deemed appropriate. If human remains are encountered, State Health and Safety Code Section 7050.5 states that no further disturbance shall occur until the County Coroner has made a determination of origin and disposition pursuant to PRC Section 5097.98. The County Coroner must be notified of the find immediately.If the remains are determined to be prehistoric, the Coroner will notify the NAHC,which will determine and notify an MLD.With the permission of the landowner or his/her authorized representative,the descendent may inspect the site of the discovery. The MLD shall complete the inspection within 48 hours of notification by the NAHC. The MLD may recommend scientific removal and nondestructive analysis of human remains and items associated with Native American burials. It is recommended that both of these measures concerning inadvertent finds of cultural material or human remains be communicated to the project engineer and contractor.Notes on the construction drawings can be a useful way to document these measures and to ensure compliance with State law.

San Jacinto,California 92583 Subject: Records Search Results for a Cultural Resources Assessment for the Ramona Expreesway Widening Project(LSA Project No. TLK1002) Dear Mr. Motlagh: LSA Associates,Inc. (LSA) is under contract to provide a records search for the Ramona Expressway Widening Project in the city of San Jacinto, Riverside County, California. The records search was performed at the Eastern Information Center (EIC) located at the University of California at Riverside, California on October 5, 2010. The EIC is part of the California Historical Resources Information System administered by the State of California Department of Park and Recreation which serves as a statewide database of all recorded cultural resource sites in the State. The EIC administers the records for Riverside County (in addition to Inyo and Mono counties). The records search included a review of all recorded historic and prehistoric archaeological sites within a one mile radius of the project area, as well as a review of known cultural resources survey and excavation reports. In addition, LSA examined the California State Historic Property Data File (HPD), which includes the National Register of Historic Places (National Register), California Historical Landmarks (CHL), California Points of Historical Interest(CPHI), and various local historic registers.

G 1 .0 Executive Summary This acoustical analysis and design evaluates the potential noise impacts and necessary mitigation measures for the Ramona Expressway (SR-79) Expansion project. The project is located along Ramona Expressway (SR-79) between Sanderson Avenue and Lake Park Drive in the City of San Jacinto, as indicated in Exhibit A. The site plan used for this analysis, prepared by RK Engineering Group, Inc. Exhibit B illustrates the site plan. The proposed project is divided into two (2) phases. Phase I starts from State Street and heads east to Lake Park Drive and will consists of adding pavement and improving the roadway segment from 2 lanes to 4 lanes. Phase 11 starts from State Street and heads west to Sanderson Avenue and will consists of adding pavement and improving the roadway segment from 4 lanes to 6 lanes. The noise regulations for the project site are listed in the Noise Standard section of the study. The study considers two (2) scenarios (a) the existing traffic noise levels and (b) predicts the future Build Alternative traffic noise levels. The existing traffic noise levels are derived from the two (2) to four (4) lane urban arterial highways, existing near lane far lane widths (20' to 27`), elevations, and existing average daily traffic (ADT) volumes. The future Build Alternative was modeled using a four (4) lane expressway for phase I and a six (6) lane expressway for phase 11, future near lane far widths (50' to 82% elevations, and the existing ADT volumes. The proposed project would be considered a Type I project by Code of Federal Regulations 23 CFR 772 due to the changes in horizontal alignments that will occur throughout the project area. This study includes short-term measurements, roadway traffic noise modeling (FHWA-RD-77-108) and recommendations for noise abatement (also graphically illustrated on Exhibit D). The noise control analysis and recommendations in this study are intended to satisfy the City of San Jacinto Conditions of Approval, with respect to this project. This report complies with 23 CFR 772, "Procedures for Abatement of Highway Traffic Noise." 1-1 1.1 Roadway Noise Analysis A roadway noise level assessment was conducted based on current ADT volumes along Ramona Expressway (SR-79), per the City's request. RK conducted a site visit to identify representative noise sensitive receiver locations, noise measurement sites, and measure and identify areas with existing sound walls. A total of seven sound walls were identified and are illustrated in Exhibit C-1 and C-2. Background noise measurements and traffic counts in three (3) segments were conducted February 18, 2009. The City of San Jacinto's Noise Element indicates that the normally acceptable exteriortinterior standard for residential land use is 65 dBA CNEL and 45 dBA CNEL, respectively. This guideline will be used to determine the potential impact to the adjacent residential community from the project site area. 1.1.1 Existing Exterior Noise Impact Monitoring results indicate that the existing traffic noise levels do not exceed the City's exterior noise standard at all of the noise sensitive areas adjacent to Ramona Expressway (SR-79). According to the short-term noise measurements combined with the vehicle distribution percentages and the monitored traffic counts, peak traffic noise occurs during morning and evening hours. 1.1.2 Future Build Alternative Exterior Noise Impact The result for the future Build Alternative indicates that the worst-case noise scenario will increase the roadway noise levels approximately -1.9 to 4.8 dBA CNEL at the representative noise receivers along Ramona Expressway (SR-79). Table 2 indicates the change in the roadway noise level from the existing conditions. The primary reason for the increase in noise level is a result of the change in distance from the centerline to the sensitive receiver. The project will therefore not generate 1-2 a substantial increase in the roadway ambient noise levels in excess of the City's regulatory standards. 1.1.3 Future Build Alternative Interior Noise Impact The interior noise projection is the difference between the exterior noise levels and the attenuating effects of the building construction shell. Typical sound level reduction of buildings is 12 dBA with windows open and 20 dBA with windows closed. Table 4 indicates the estimated interior noise levels of for the representative receivers. Under a "windows open" condition the interior noise levels will exceed the City's interior noise criteria, therefore a "windows closed" condition is required to meet the City's interior noise standard. With windows closed it is expected that interior noise levels will range from 38.6 to 44.9 dBA CNEL as indicated in Table 4. 1.2 Construction Noise Analysis Construction noise represents a short-term impact on the ambient noise levels. The degree of construction may vary for different areas of the project corridor; as a result noise levels associated with construction will vary. Noise generated by construction equipment can reach high levels. Typical construction equipment includes trucks, graders, backhoes, pavers, and portable generators. The peak noise level for most of the equipment that will be utilized during the construction phase will be approximately 70 — 90 dBA at a distance of 50 feet from the noise source. The land uses along Ramona Expressway between Sanderson Avenue and Lake Park Drive include residential and undeveloped land uses with commercial land use located in between the project area. The worst-case project exterior construction noise will range approximately from 72.0 to 76.7 dBA Equivalent Noise Level (Leq) with a maximum level of 80 dBA Lax. The noise level will vary depending on the distance and existing topography. 1-3 The City has adopted the construction activity noise regulations from the Municipal Code (8.40.090). Construction activities must follow the noise regulations as outlined in the municipal code. Refer to Section 2.0 Summary of Mitigation Requirements for noise reduction measures or noise regulations that would potentially reduce construction impacts to a less than significant level. 1 W4 2.0 Summary of Mitiqation Requirements Roadway and construction noise impacts from the Ramona Expressway (SR-79) Expansion project were assessed and compared to the City of San Jacinto's exterior/interior noise standards for residential land use. The results of the roadway CNEL analysis include existing traffic noise levels and future Build Alternative traffic noise levels along Ramona Expressway (SR-79) as detailed in Table 2. The results of the construction noise analysis assume a worst-case scenario during the grading phase as detailed in Table 6. A summary of all noise requirements, recommendations and locations are shown on Exhibit D. Based on the conditions set-forth by the City, the proposed project is not expected to have a significant impact on the adjacent land uses. However, to ensure noise levels remain low there are several required and recommended noise reduction measures to reduce noise impacts. 2.1 Roadway Noise Reduction Measures For representative receivers 1 through 6 it is anticipated that no further shielding will be required to meet the City's exterior standard of 65 dBA CNEL. Table 2 indicates the results of the barrier analysis and includes the existing barrier heights at the respective receiver locations. Representative receiver seven (R7) existing and predicted future exterior noise level will exceed the 65 dBA CNEL standard. R7 is located along the frontage road, Idllywild Drive which runs parallel to Ramona Expressway. The residential units represented by R7 do not have an existing wall to shield traffic noise levels. R7 has no useable outdoor areas (i.e. backyard/ patio) therefore it is not required to further shield the residential units represented by R7. 2-1 2.2 Construction Noise Reduction Measures Construction operations must follow the noise ordinance which states that operations must occur between the hours of 7:30 AM to 6:00 PM, Monday through Friday (Chapter 8.40.90). A number of noise reduction measures are suggested to minimize noise impacts. 1. During construction, the contractor should ensure all construction equipment is equipped with appropriate noise attenuating devices. 2. Idling equipment should be turned off when not in use. 3. Equipment will be maintained so that parts of vehicles and their loads are secured from rattling and banging. 4. If noise complaints demonstrate that a significant noise impact is affecting sensitive noise receptors do to construction activities (noise levels as measured at the receptor location), the City may require the contractor to apply further measures to reduce noise impact by implementing a noise and vibration control plan which is indicated as follows: a. Pursuant to the City's request, portable sound level meters would be utilized to determine and verify the noise impact from the construction equipment to the sensitive receptor location. 2-2 3.0 Fundamentals of Noise This section of the report provides basic information about noise and presents some of the terms used within the report. 3.1 Sound, Noise and Acoustics Sound is a disturbance created by a moving or vibrating source and is capable of being detected by the hearing organs. Sound may be thought of as mechanical energy of a moving object transmitted by pressure waves through a medium to a human ear. For traffic, or stationary noise, the medium of concern is air. Noise is defined as sound that is loud, unpleasant, unexpected, or unwanted. 3.2 Frequency and Hertz A continuous sound is described by its frequency (pitch) and its amplitude (loudness). Frequency relates to the number of pressure oscillations per second. Low-frequency sounds are low in pitch (bass sounding) and high-frequency sounds are high in pitch (squeak). These oscillations per second (cycles) are commonly referred to as Hertz (Hz). The human ear can hear from the bass pitch starting out at 20 Hz all the way to the high pitch of 20,000 Hz. 3.3 Sound Pressure Levels and Decibels The amplitude of a sound determines it loudness. The loudness of sound increases or decreases as the amplitude increases or decreases. Sound pressure amplitude is measure in units of micro-Newton per square inch meter (N/m2), also called micro-Pascal (uPa). One juPa is approximately one hundred billionths (0.00000000001) of normal atmospheric pressure. Sound pressure level (SPL or Ld 3-1 is used to describe in logarithmic units the ratio of actual sound pressures to a reference pressure squared. These units are called decibels abbreviated dB. 3.4 Addition of Decibels Because decibels are on a logarithmic scale, sound pressure levels (SPL) cannot be added or subtracted by simple plus or minus addition. When two sounds or equal SPL are combined, they will produce an SPL 3 dB greater than the original single SPL. In other words, sound energy must be doubled to produce a 3 dB increase. If two sounds differ by approximately 10 dB the higher sound level is the predominant sound. 3.5 Human Response to Changes in Noise Levels In general the healthy human ear is most sensitive to sounds between 1 ,000 Hz and 5,000 Hz, (A-weighted scale) and it perceives a sound within that range as being more intense than a sound with a higher or lower frequency with the same magnitude. For purposes of this report as well as with most environmental documents, the A-scale weighting is typically reported in terms of A-weighted decibel (dBA). Typically the human ear can barely perceive the change in noise level of 3 dB. A change in 5 dB is readily perceptible, and a change in 10 dB is perceived as being twice or half as loud. As previously discussed, a doubling of sound energy results in a 3 dB increase in sound, which means that a doubling of sound energy (e.g. doubling the volume of traffic on a highway) would result in a barely perceptible change in sound level. 3.6 Noise Descriptors Noise in our daily environment fluctuates over time. Some noise levels occur in regular patterns other are random. Some noise levels are constant while others are sporadic. Noise descriptors were created to describe the different time-varying noise 3-2 levels. Appendix B indicates the most commonly used noise descriptors and gives a brief definition. 3.7 Traffic Noise Prediction Noise levels associated with traffic depends on a variety of factors: (1) volume of traffic, (2) speed of traffic, (3) auto, medium truck (2 — 6 wheels) and heavy truck percentage (3 axle and greater), and sound propagation. The greater the volume of traffic, higher speeds and truck percentages equate to a louder volume in noise. A doubling of the Average Daily Traffic (ADT) along a roadway will increase noise levels by approximately 3 dB; reasons for this are discussed in the sections above. 3.8 Sound Propagation As sound propagates from a source it spreads geometrically. Sound from a small, localized source (i.e., a point source) radiates uniformly outward as it travels away from the source in a spherical pattern. The sound level attenuates at a rate of 6 dB per doubting of distance. The movement of vehicles down a roadway makes the source of the sound appear to propagate from a line (i.e., line source) rather than a point source. This line source results in the noise propagating from a roadway in a cylindrical spreading versus a spherical spreading that results from a point source. The sound level attenuates for a line source at a rate of 3 dB per doubling of distance. As noise propagates from the source, it is affected by the ground and atmosphere. Noise models use hard site (reflective surfaces) and soft site (absorptive surfaces) to help calculate predicted noise levels. Hard site conditions assume no excessive ground absorption between the noise source and the receiver. Soft site conditions such as grass, soft dirt or landscaping attenuate noise at an additional rate of 1 .5 dB per doubling of distance. When added to the geometric spreading, the excess ground attenuation results in an overall noise attenuation of 4.5 dB per 3-3 doubling of distance for a line source and 6.0 dB per doubling of distance for a point source. Research has demonstrated that atmospheric conditions can have a significant effect on noise levels when noise receivers are located 200 feet from a noise source. Wind, temperature, air humidity and turbulence can further impact have far sound can travel.

The study includes an evaluation of the existing sound walls as well as the need for potential sound barriers for residential units impacted by traffic noise. The Ramona Expressway (SR-79) Expansion project is located along Ramona Expressway (SR-79) between Sanderson Avenue and Lake Park Drive in the City of San Jacinto. The general location of the project is shown in the Location Map, Exhibit A. The site plan used for this analysis, provided by .RK Engineering, Inc and is presented on Exhibit B. The purpose of the Ramona Expressway (SR-79) Expansion Project is to accommodate future travel demand and improve traffic operations and safety by widening the existing Ramona Expressway. For purposes in this study, Ramona Expressway (SR-79) was divided into two (2) phases. Phase I starts from State Street and heads east to Lake Park Drive and will consists of adding pavement and improving the roadway segment from 2 lanes to 4 lanes. Phase II starts from State Street and heads west 'to Sanderson Avenue and will consists of adding pavement and improving the roadway segment from 4 lanes to 6 lanes. This study analyzes a Build Alternative for future conditions utilizing the existing traffic volumes per the City's request. The following briefly describes the Build Alternative. Build Alternative The proposed Ramona Expressway (SR-79) Expansion Project would: (a) reconfigure the existing road for phase I from two (2) lanes to four (4) lanes and reconfigure phase 11 from four (4) lanes to six (6) lanes. It assumes either a four (4) or six (6) expressway (depending on which phase was being analyzed), future near lane far 4-1 lane widths (50' to 80'), elevations, and the existing ADT volumes for the phase I and phase II roadway segments. The traffic data is listed in Table 3. The predicted future Build Alternative traffic noise levels are compared to City's noise regulations. The following sections outline the applicable noise regulations. The design requirements and recommendations, as outlined in the Summary of Mitigation Requirements section of this study, are intended to satisfy the City of San Jacinto's noise regulations. 4.1 Noise Regulations The acoustical parameters, including the City Noise Regulations from the Noise Element, are included in Appendix A. The noise regulations include roadway noise impacts. 4.1.1 Roadway Noise Regulations Roadway noise impacts, specified within the Noise Element at the normally acceptable level should be below the 65 dBA CNEL exterior and 45 dBA CNEL interior residential land use thresholds. 4.1.2 Construction Noise Regulations The City of San Jacinto has adopted Exterior Noise Standards set forth by the City's Noise Ordinance. Construction noise is defined as noise which is disturbing, excessive or offensive and constitutes a nuisance involving discomfort or annoyance to persons of normal sensitivity residing in the area, which is generated by the use of any tools, machinery or equipment used in connection with construction operations. Construction operations shall take place Monday through Friday between the hours of 7:30 AM and 6:00 PM. Figure 1 indicates the stationary and construction noise standards. 4-2 Figure 7 Noise Ordinance Stationary Noise Standards Noise Criteria Level (dBA) Cumulative Time 0 Time Period Average Minutes Tme Symbol Leo L..

Appendix B contains more definitions and examples. 4-3 THIS PAGE INTENTIONALLY LEFT BLANK 4-4 5.0 Study Method and Procedure A glossary of acoustical terms is included in Appendix B. 5.1 CNEL (Community Noise Equivalent Level) Roadway Noise Modeling The CNEL Roadway noise analysis uses a version of the Federal Highway Administration (FHWA) Traffic Noise Prediction Model (FHWA-RD-77-108), together with several key roadway and site parameters. Key inputs include roadway classification (e.g. Highway, Urban Arterial Highway, Secondary Highway, and Industrial Collector), roadway active width (the distance between the center of the outer most travel lanes on each side of the roadway), Existing Average Daily Traffic (ADT) obtained by RK traffic counts (per City request), travel speed, percentages of automobiles, medium trucks and heavy trucks in the roadway volume, roadway grade, angle of view, site conditions ("hard" or "soft"), and percent of total ADT which flows each hour throughout a 24-hour period. Using the Noise Barrier Calculations and the key parameters, a barrier analysis was performed to determine noise computations. The key input data for these barrier performance equations include relative source-barrier-receiver horizontal separations, relative source-barrier-receiver vertical separations, typical noise source spectra, and barrier transmission loss. Some of the general assumptions used in determining the source and receiver geometry are listed below: Receiver Geometry Horizontal Geometry: Distance behind top-of-slope barrier: Varies Vertical Geometry: Refer to stationary noise model a-1 Source Assumptions Horizontal Geometry: For roadways with grades no greater than 2%, all vehicles are located at the single-lane equivalent acoustical center of the full roadway. For roadways with over 2% grade, vehicle count is divided in half and is located at the single- lane acoustical equivalent for each side of the roadway. Vertical Geometry: Height above road grade: Autos: 2.0 feet Medium Trucks: 4.0 feet Heavy Trucks: 8.0 feet The CNEL Roadway model calculates the noise impacts produced by the adjacent roadway. The output of the model was compared to the Residential Land Use Noise Standards found in the Noise Element. The City has an exterior normally acceptable single family residential standard of 65 dBA CNEL and interior standard of 45 dBA CNEL. Appendix D contains all predicted noise calculations. The predicted future Build Alternative indicates that the worst-case noise scenario will increase the roadway noise levels over existing levels by approximately -1 .9 to 4.8 dBA CNEL at the representative noise receivers along Ramona Expressway (SR-79). Most of this increase is as a result changing the horizontal center of the Ramona Expressway (SR-79). 5.2 Noise Measurements Noise measurements are taken to determine the existing noise levels. A noise receiver or receptor is any location in the noise analysis in which noise might produce an impact. The following criteria are used to select measurement locations and receptors. • Locations expected to receive the highest noise impacts, such as first row of houses 5-2 • Locations that are acoustically representative and equivalent of the area of concern • Human land usage • Sites clear of major obstruction and contamination Noise measurements were conducted on February 18, 2009 using a Larson Davis 712 sound level meter. The following gives a brief description of the Caltrans Technical Noise Supplement procedures: • Microphones for sound level meters were placed 5-feet above the ground for all measurements • Sound level meters were calibrated before and after each measurement • Following the calibration of equipment, a wind screen was placed over the microphone • Frequency weighting was set on "A" and slow response • Results of the short-term noise measurements were recorded on field data sheets • During short-term noise measurements any noise contaminations such as barking dogs, local traffic, lawn mowers, or aircraft fly-overs were noted • Temperature and sky conditions were observed and documented 5-3 THIS PAGE INTENTIONALLY LEFT BLANK 5-4 6.0 Existing Noise Environment RK visited the project site on February 18, 2009 to identify representative noise sensitive receiver locations, noise measurement sites, and measure and identify areas with existing noise barriers. All residential areas within the project limits are protected from traffic noise by existing noise barriers with a height equal or less than 7.5 feet. Background noise measurements were conducted during the visit to evaluate the existing background noise levels in the vicinity of the project area. The locations of the monitoring sites and noise sensitive receivers are shown in Exhibits C-1 and C-2. Daily traffic data was collected on February 18, 2009 at three locations on Ramona Expressway (SR-79). Phase I (State Street to Lake Park Drive) had an existing ADT of 17,286. Phase li (State Street to Sanderson Avenue) had an existing ADT of 17,194. The existing traffic counts and terrain conditions are entered into the noise model, and the computer output is compared with the noise levels recorded at the same time the traffic count was made. This comparison yields a calibration factor that is used to adjust the model. Measured and calculated noise levels were within 0.1 to 0.3 dB of each other. This represented a close calibration of the measured and model noise data. Appendix E contains the traffic count data and converted CNEL data. Existing noise levels at the representative noise receivers listed in Table 2 were either measured or estimated. The existing noise levels at some of the representative receiver locations were estimated by utilizing the computer model and comparing the model output to the measured noise levels at the receiver which have similar geographical similarity relative to Ramona Expressway (SR-79). Appendix F contains the representative receiver locations and distances for the project area. 6-1 6.1 Project Area On February 18, 2009 seven (7) short-term noise measurements were conducted along the project alignment during the site visit. Short-term measurements were adjusted to reflect the twenty four (24) hour CNEL by using the daily traffic data and the hourly traffic distribution. The data was inputted into a CNEL calculator that utilizes hourly traffic data and noise data, A summary of the noise monitoring results is shown in Table 1. Photographs of the measurement sites are shown in Appendix C. The monitoring results indicate that the existing traffic noise levels were below the City's noise criteria of 65 dBA CNEL for all noise measurement location except at R7. The measured noise levels ranged from 58.5 to 66.3 dBA CNEL (Table 2). R7 noise measurement was performed near the front yard of an existing residential units located along Ramona Expressway(SR-79). 6-2 7.0 Future Noise Environment and Impacts 7.1 Future Exterior Noise The future exterior noise levels analyze roadway noise impacts associated with the project area. 7.1.1 Roadway Noise Data The City has a normally acceptable exterior residential standard of 65 dBA CNEL for transportation noise. As summarized in Table 2, the predicted future Build Alternative CNEL at the representative receiver locations range from approximately 58.6 to 66.6 dBA CNEL, exceeding the City's exterior noise standard at one of the representative receiver locations. R7 is the only representative receiver where the noise level exceeds the City's standard. However, there are no noise sensitive outdoor areas for receiver location R7. The results of the roadway noise analysis indicate that traffic noise levels are not expected to exceed the City's exterior noise threshold of 65 dBA CNEL for receivers 1 through 6. It is anticipated that existing wall heights along the project site corridor are at a sufficient height to meet the City's exterior standard, based on the existing ADT volumes obtained by RK Engineering Group Inc. Future build-out volumes along Ramona Expressway were not analyzed per the City's request. 7.2 Future Interior Noise Typical building construction will provide a conservative 12 dBA noise level reduction with "windows open" and a very conservative 20 dBA noise level reduction with "windows closed". Using typical building construction reduction levels, the future interior noise levels, within the project site were calculated. The projected interior 7-1 noise impacts to the residential units closest to Ramona Expressway will range from approximately 38.6 to 44.9 dBA CNEL, as indicated in Table 3. A "windows closed" condition is required to meet the Gty's interior noise standard of 45 dBA CNEL. 7-2 8.0 Construction Noise Impacts The degree of construction noise may vary for different areas of the project site and also vary depending on the construction activities. It is estimated that construction will take approximately six months per phase to grade and construct the project (12 months total). Noise levels associated with the construction will vary with the different phases of construction. Construction noise is expected to be the worse during the grading and paving phases of construction. The following is a list of heavy construction equipment which will be utilized during construction. It is expected that one (1) grader and (1) backhoe will be used during construction grading phase. The Environmental Protection Agency (EPA) has compiled data regarding the noise generated characteristics of typical construction activities. The data is presented in Table 4, These noise levels would diminish rapidly with distance from the construction site at a rate of 6 dBA per doubling of distance. For example a noise level of 86 dBA measured 50 feet from the noise source would reduce to 80 dBA at 100 feet. At 200 feet from the noise source the noise level would reduce to 74 dBA. At 400 feet the noise source would reduce by another 6 dBA to 68 dBA. During the construction period, the contractors would be required to comply with the Municipal Code of the City of San Jacinto as described in Appendix A. The worst-case projected noise levels are expected to range from 72.0 to 76.7 dBA Lq with a maximum level of 80.0 dBA La, as indicated in Table 6. Noise reduction measures can still be implemented by the contractor to further reduce construction noise impacts. 8-1 THIS PAGE INTENTIONALLY LEFT BLANK 8-2 9.0 Conclusions RK has completed an acoustical analysis of the Ramona Expressway (SR-79) Expansion project, located in the City of San Jacinto. The project was assessed with respect to the existing traffic noise conditions in the project area, identifying noise sensitive locations, predicting the future Build Alternative traffic noise levels, estimating the interior noise levels and projecting the construction noise impacts. The roadway noise analysis indicates that the future Build Alternative traffic noise levels do not exceed the City's exterior noise standard. The following conclusions for the Ramona Expressway (SR-79) Expansion project are listed below: • The existing and future Build Alternative traffic noise impacts are indicated in Tables 1 and 2. No significant impact is expected as a result of the project. ■ The predicted future interior noise levels are indicated in Table 3. • The projected construction noise levels are indicated in Table 6. • A summary of the recommended mitigation for the project area are listed in Table 2. (See Summary of Mitigation Requirements Section 2.0 for required mitigation) Noise reduction measures are recommended in the report. A summary of these recommendations can be found in Section 2.0 (pages 2-7 to 2-2) of this report. The analysis and design presented in this study comply with applicable City of San Jacinto requirements for control of community noise impacts to exterior living areas, for residential land use. 9-1 THIS PAGE INTENTIONALLY LEFT BLANK 9-2 Exhibits Exhibit A Location Map m a C 0 C c m rn •�t ♦s�1; marsh; � ♦, hb' N ♦ u � L♦-, o N' m v c �h d 25 a o pc_ � c N ai h G! y Main SC Legend: -----0-=Phase I rm�mr=Phase 2 I N 0328-09-f)S(6og engineering RAMONA EXPRESSWAY(SR-79)EXPANSION,City of San Jacinto,California group, inc. t> r I I 7i k, M ,. sfr i xE v PRO§r ' re�'CS�. 3 ''-�+I' ,: S-fS -a S/ """.

(Ord. 07-17 § 2 (part)) 8.40.020 Definitions. As used in this chapter, specific words and phrases are defined as follows: "A-weighted sound level" shall mean the sound pressure level in decibels (dBAs) as measured with a sound level meter using the A-weighted filter network (scale) at slow response and at a pressure of twenty (20) micropascals. The A-weighted filter de-emphasizes the very low and a very high frequency component of sound in a manner similar to the response of the human ear, and is a numerical method of rating human judgment of loudness. °Ambient noise level"shall mean the all-encompassing noise level associated with a given environment and is a composite of sounds from all sources, excluding the alleged offensive http://www.codepublishing.com/CA/SanJacinto/SanJacinto08/SanJacintoD840.html 2/23/2009 Chapter 8.40 NOISE CONTROL Page 2 of 11 noise or excessive sound, at the location and approximate time at which a comparison with the alleged offensive noise is to be made. "Applicable (noise) zone" shall mean the noise zone category based on the actual use of the property; provided, that the actual use is a legal use in the city of San Jacinto. "Decibel (dBA)" shall mean a unit for measuring the amplitude of a sound, equal to twenty (20)times the logarithm to the base ten (10) of the ratio of pressure of the sound measured to the reference pressure of twenty (20) micropascals. "Equivalent sound or noise level (Leq)"shall mean the International Electrotechnical Commission (IEC) 60804 Standard for measurement, or the most recent revision thereof, for the sound level corresponding to a steady state noise level over a given sample period with the same amount of acoustic energy as the actual time varying noise level or the energy average noise level during the sample period. The measurement period for the purposes of this chapter is fifteen (15) minutes. "Impulsive noise" shall mean a noise of short duration usually less than one second and of high intensity, with an abrupt onset and rapid decay. Such objectionable noises may also be repetitive. "Intrusive noise" shall mean that noise that intrudes over and above the ambient noise at a given location.

Community Noise Equivalent Level(CNEL) The average equivalent A-weighted sound level during a 24-hour day, obtained after addition of five (5) decibels to sound levels in the evening from 7:00 to 10:00 PM and after addition of ten (10) decibels to sound levels in the night before 7:00 AM and after 10:00 PM. Decibel(de) A unit for measuring the amplitude of a sound, equal to 20 times the logarithm to the base 10 of the ratio of the pressure of the sound measured to the reference pressure, which is 20 micro-pascals. dB(A) A-weighted sound level (see definition above). Equivalent Sound Level (LEQ) The sound level corresponding to a steady noise level over a given sample period with the same amount of acoustic energy as the actual time varying noise level. The energy average noise level during the sample period. Habitable Room Any room meeting the requirements of the Uniform Building Code or other applicable regulations which is intended to be used for sleeping, living, cooking or dining purposes, excluding such enclosed spaces as closets, pantries, bath or toilet rooms, service rooms, connecting corridors, laundries, unfinished attics, foyers, storage spaces, cellars, utility rooms and similar spaces. L(n) The A-weighted sound level exceeded during a certain percentage of the sample time. For example, L10 in the sound level exceeded 10 percent of the sample time. Similarly L50, L90 and L99, etc. Noise Any unwanted sound or sound which is undesirable because it interferes with speech and hearing, or is intense enough to damage hearing, or is otherwise annoying. The State Noise Control Act defines noise as "...excessive undesirable sound...". Outdoor Living Area Outdoor spaces that are associated with residential land uses typically used for passive recreational activities or other noise-sensitive uses. Such spaces include patio areas, barbecue areas, jacuzzi areas, etc. associated with residential uses; outdoor patient recovery or resting areas associated with hospitals, convalescent hospitals, or rest homes; outdoor areas associated with places of worship which have a significant role in services or other noise- sensitive activities; and outdoor school facilities routinely used for educational purposes which may be adversely impacted by noise. Outdoor areas usually not included in this definition are: front yard areas, driveways, greenbelts, maintenance areas and storage areas associated with residential land uses; exterior areas at hospitals that are not used for patient activities; outdoor areas associated with places of worship and principally used for short-term social gatherings; and, outdoor areas associated with school facilities that are not typically associated with educational uses prone to adverse noise impacts (for example, school play yard areas). Percent Noise Levels See L(n). Sound Level (Noise Level) The weighted sound pressure level obtained by use of a sound level meter having a standard frequency-filter for attenuating part of the sound spectrum. Sound Level Meter An instrument, including a microphone, an amplifier, an output meter, and frequency weighting networks for the measurement and determination of noise and sound levels. Single Event Noise Exposure Level (SENEL) The dB(A) level which, if it lasted for one second, would produce the same A-weighted sound energy as the actual event.

(LSA)at the Ramona Expressway Road Widening Project located within the City of San Jacinto.The proposed project site is the segment of the Ramona Expressway between Sanderson Avenue and Lake Park Drive. Overall, the proposed project consists of widening of Ramona Expressway, pavement widening with new curb/gutter, and related drainage and infrastructure improvements.No acquisition of right-of-way is anticipated. The project site is located in Sections 17,20, 29, and 32,Township 4 South,Range 1 West as shown on the U.S. Geological Survey(USGS)Inkevi.ew, California and San Jacinto, California 7.5-minute series topographic maps. The existing right-of-way will accommodate the proposed improvements.The proposed project is divided into two(2)phases: Phase I: From Sanderson Avenue to Eagle Road Phase 1 of the Ramona Expressway widening project consists of improving the roadway segment from a total of four(4) lanes to a total of six(6) lanes between Sanderson Avenue and Eagle Road. This phase also consists of pavement widening with new curb/gutter on both sides of centerline and coucrete sidewalk on both sides. The widening will create three lanes of traffic in either direction,a center left-torn pocket or landscaped median, and minimal drainage improvements. The improvements will include adjustment and relocation of existing traffic signal poles. Phase 11: From Eagle Road to Main Street/Lake Park Drive This phase consists of the segment from Eagle Road to Main Street/Lake Park Drive widening from total of two(2) lanes to a total of four(4) lanes. The project also includes pavement widening to provide for nunilnum of two lanes of traffic in each direction;one left-turn pocket or striped median including 5 to 8 feet of paved shoulder, and minimal drainage improvements. This project will also include adjustment and relocation of existing traffic signal poles. 6/102011(RATLK1002_Ramona Fxp\13to\SIJ0W Repori.doc) PLANNING I ENY I RON AICNTAL I OESIGN I.SA ASSOCIATES, INC. BACKGROUND The western burrowing owl is a small to median-sized,ground-dwelling owl with a round head that lacks the tufts of feathers typical of other owls. It has white eyebrows,yellow eyes, and long stilt-like legs. The owl is sandy-colored on [he head, back, and upper parts of the wings and white-to-cream with barring on the breast and belly.Unlike most owls, the male and females are about the same size; however,the females are usually darker in plumage color than the males. Burrowing owls are found in open, dry grasslands, agricultural,range lands,railroad rights-of-way, margins of highways;golf courses, and airports. In desert habitats,their typical habitat is sagebrush scrub along fence lines and dry washes.They can also inhabit grass,forb and shrub stages of pinyon and ponderosa pine habitats. The owl conunonly perches on fence posts in rural areas or on top of mounds outside its burrow, In all habitats,they are often associated with burrowing animals. The owl can be found at elevations ranging from 200 feet below sea level to 12,000 feet above sea level. i Burrowing owls tend to be opportunistic feeders. Large arthropods, mainly beetles and grasshoppers, comprise a large portion of their diet. Small mammals, especially note, rats, gophers,and ground squirrels,are also important food items. Other prey animals include reptiles and amphibians, scorpions, young cottontail rabbits, bats, and birds, such as sparrows and horned larks. Consumption. of insects increases during the breeding season. Burrowing owls are primarily crepuscular(active at dusk and dawn) but will hunt throughout a 24-hour period. As their name suggests,burrowing owls nest in burrows in the ground, often in old ground squirrel burrows or abandoned skunk, fox, or badger dens.Burrowing owls prefer to move into deserted burrows of other animals. They can and do dig their own burrows when necessary, a task undertaken most often in soft,sandy soil that they can excavate easily using their beaks and feet. They are also known to use artificial burrows or deserted piping. Burrowing owl nesting season begins between February and April and lasts until the end of August. The peak of the nesting season is from April 15 to July 15.The owls often line their nests with an assortment of dry materials. Adults usually return to the same burrow or a nearby area each year. One or more"satellite"burrows call usually be found near the nest burrow,and are used by adult males during the nesting period and by_juvenile owls for a few weeks after they emerge from the nest. The female will lay six to nine(sometimes up to 12) white eggs a day apart, which are incubated for 28-30 days by the female only.The male brings food to the female during incubation,and stands guard near the burrow by day. At 14 days of age, the young may be seen roosting at the entrance to the burrow, waiting for the adults to return with food.The young leave the nest at about 44 days of age and begin chasing live insects at between 49 and 56 days old. 3 The western burrowing owl is found in western North America from Canada to Mexico, and east to Texas and Louisiana. In certain areas of its range, it is migratory;this includes the northern areas of the Great Plains and Great Basin.Although the burrowing owls in northern California are thought to migrate, owls within central and southern California are predominantly uomnigratory. The burrowing owl is protected by international treaty under the Migratory Bird Treaty Act(MBTA) of 1918 (16 U.S.C. 703-71.1)and is protected under Section 3503 of California Fish and Game Code 6/1 0120 1 1(RATLK1001_Runona ExplBio\BUOw Repon.doc) 2 LSA ASSOCIATES, INC. (CDFG).This species of owl is considered it"species of special concern"by the California Department of Fish and Game(CDFG)and the CDFG is currently reviewing a petition to list the burrowing owl as it Threatened or Endangered species. Sections 3503. 3503.5, and 3800 of the CDFG Code prohibit the take, possession,or destruction of birds, their nests,or eggs.When the owl is present on a subject property,implementation of the take provisions requires that project-related disturbance at active nesting territories be reduced or eliminated during critical phases of the nesting cycle(February 1 through August 31). METHODS LSA followed the Burrowing Owl Consortium 1993 Borrowing Owl Survey Protocol and Mitigation Guidelines' and referred to the Western Riverside County Multiple Species Habitat Conservation Plan(MSHCP)survey instructions'-to complete the pre-construction burrowing owl survey. Phase 1: Habitat Assessment and Phase 1I: Burrow Survey was completed as required in the Burrowing Owl Consortium survey protocol. ENVIRONMENTAL SETTING The proposed project is in the northern portion of the City of San Jacinto.The land surrounding the project site is mainly agricultural and rural.residential between Sanderson Avenue and Potter Road. The surrounding land between Potter Road and San Jacinto Avenue is more urbanized with commercial developments, the San Jacinto Community College campus and residential.The proposed project area is level with maintained road shoulders, numerous road and driveway access points, and right-of-way fence, chain lank fence, or block walls along the perimeter. RESULTS A previous habitat suitability assessment(has)was done as part of the biological resources report in December 2009.A wintering owl was occupying a burrow in the right-of-way between Sanderson Avenue and Potter Road. The previously occupied burrow was not found and no owls were observed in the previously occupied location. A site visit was completed as a second HAS on May 18,2011. The.right-of-way segments within the agricultural land use areas have the greatest potential to be occupied by burrowing owl. California ground squirrels (Spennophihis beecheyi) were found throughout the right-way; especially near culverts, in the fence rows,rip-rap,and earthen berms. The site was densely covered with annual grasses in portions of the right-of-way,but also mowed, sprayed,or graded in other areas. Some areas were covered with Russian thistle(Salsola tragus) and other tumbleweeds(Amarmrtha sp.).The adjacent dry land grain crops were already harvested. No sites had native plant communities adjacent to the right-of-way.

The trapping was conducted to determine the presence or absence of the federally endangered San Bernardino kangaroo rat (Dipodomys arerrianai parvus)(SBKR)and the State Species of Special Concern Los Angeles pocket mouse(Perognathus longimembris brevinasus)(LAPM)within the Western Riverside County Multiple Species Habitat Conservation Plan(MSHCP) Species Survey Area.The trapping was conducted according to survey guidelines established by the United States Fish and Wildlife Service(USFWS)and California Department of Fish and Game(CDFG). STUDY AREA The study area covers Phase II of the project, which is located adjacent to the Ramona Expressway from Main Street/Lake Park Drive to approximately 0.8 mile north, in the City of San Jacinto, Riverside County, California(see Figure 1,attached).Phase I of the project from Sanderson Avenue to Eagle Road is not located within the designated MSHCP survey area for the San Bemardino kangaroo rat and the Los Angeles pocket mouse. The five trapping areas are located on both sides of the Expressway and within the right-of-way for the proposed Ramona Expressway Widening project (see Figure 2, attached). Surrounding land use includes the San Jacinto River to the east and agricultural fields and residential development to the north,west, and south. The study area is in projected Sections 25 and 36,Township 4 South,Range I West as shown on the U.S. Geological Survey(USGS)San Jacinto, California quadrangle 7.5-minute series topographic map. Phase II: From Eagle Road to Main Street/Lake Park Drive Phase II consists of the segment from Eagle Road to Main Street/Lake Park Drive widening from two (2) lanes to a total of four(4) lanes. The project also includes pavement widening to provide for minimum of two lanes of traffic in each direction„one left-turn pocket or striped median including 5 to 8 feet of paved shoulder, and minimal drainage improvements. This project will also include adjustment and relocation of existing traffic signal poles.

The vegetation within the study area is predominantly annual grasses and ruderal nonnative vegetation along the right-of-way of the Ramona Expressway. However,the north and south-facing slopes of Lake Park Drive/Main Street contain remnant coastal sage scrub plant community.The elevation of the study area ranges from approximately 1,570 to 1,600 feet above mean sea level. The substrates of the study area include loose sand and sandy loam. METHODS Mamie McKeman, Wendy Walters, and Richard Erickson conducted protocol-level live trapping for 5 consecutive nights during the week of July 10, 2011, to determine the presence/absence of SBKR and LAPM,their relative abundance,and breeding status within the project site. Mamie McKeman trapped under Federal 10(a)(1)(A)Permit No. TE-839211-3 (expires April 2015)and CDFG Permit No. SC-004753 and Memorandum of Understanding(MOU)(expires April 2013). Wendy Walters and Richard Erickson trapped under LSA Associates, Inc. (LSA)Federal 10(a)(1)(A)Permit No. TE-777965-8 (expires April 17,2012)and CDFG Permit No. SC-00777 (expires April 30, 2012). Claudia Bauer, Erin Martinelli, and Denise Woodard assisted with the trapping efforts. A total of 151, 12-inch Sherman live traps were set along linear transects(Figure 2). In general,traps were placed between 5 and 10 meters apart within the right-of-way of the proposed road widening, concentrating on placing traps where sandy soils and/or suitable vegetation were present.Two traplines were set within the Ramona Expressway/Lake Park Drive intersection right-of-way,one within the southeast quadrant of the intersection and the other within the northeast quadrant.All four of the remaining traplines were set 4,000 feet north of the intersection. Two traplines set were on the east side of Ramona Expressway and two traplines were set on the west side of Ramona Expressway (see Figure 2). Trapping was conducted in this portion of the project area because it is located within the designated MSHCP survey area for the San Bernardino kangaroo rat and the Los Angeles pocket mouse(Figure 3). Each trap was baited with a mixture of birdseed and rolled oats, and placed at the back of the traps. The traps were left in place and opened at dusk each night and inspected once at midnight and at dawn each morning. All animals were identified and released at the point of capture. Weather conditions during the trapping surveys were noted and included morning temperatures varying from 55 to 61°F with clear to partly cloudy skies and no wind. No ground fog or rain occurred during the survey periods. RESULTS Six small mammal species were trapped during the five-night trapping effort.No San Bernardino kangaroo rats were captured but several Los Angeles pocket mice were caught. One additional special-status mammal species—northwestem San Diego pocket mouse(Chaetodipus fallax fallczx) was captured as well. There were 24 Los Angeles pocket mouse captures during the trapping effort, of which all but two were determined to be in a reproductive state. Presumably many of these captures involved the same individuals,but none of the animals were marked prior to release.

(LSA) was retained by the City of San Jacinto to conduct several biological surveys for widening the Ramona Expressway within the city limits. The project study area was found to contain occupied habitat for the Los Angeles pocket mouse (Perognathus longimembris brevinasus)(LAPM). Thus, in compliance with Section 6.3.2-Additional Survey Needs and Procedures in the Western Riverside County Multiple Species Habitat Conservation Plan(MSHCP), this report will document the feasible alternative and mitigation measures for unavoidable impacts to LAPM. The proposed new pavement and road shoulder will cause impacts to 2.2 acres of the 6.5 acres of unpaved ground within the segment of the Ramona Expressway right-of-way within the MSHCP Mammal Survey Area. Since the project impact area is over the acreage amount to be less than the 90 percent avoidance threshold, a Determination of Biologically Equivalent or Superior Preservation (DBESP)is necessary per MSHCP guidelines. The project cannot meet the 90 percent avoidance threshold because of the narrow linear nature of the impacts associated with a road widening project. The construction of the additional lane is already designed to limit work to one side of the existing roadway. The purpose of this DBESP report is to discuss the mitigation for impacts to 2.2 acres of occupied LAPM habitat in the segment of Ramona Expressway right-of-way within the MSHCP Mammal Survey Area/LAPM occupied habitat; to describe the most practicable alternative with the proposed project design; to provide specific quantities of direct impacts; the most feasible compensation measures;and to document that the proposed compensation measures are equivalent or superior to avoiding 1.6 acres of unpaved ground in the right-of-way that required to meet the 90 percent avoidance threshold. The proposed preservation is to compensate the RCA for a part of the purchase price($14,629 per acre)for a portion of the Geller#3 conservation land; specifically,2.2 acres of the 40-acre parcel(APN 583-180-001). RATLK1002_Ramona Ezp.Bio1MSHCP DBESP JPRIDBESP_final_AH_Ciry.doc(11/312011) 111 1.0 PROJECT DESCRIPTION 1.1 PROJECT LOCATION The proposed project site is located in the northeast portion of the City of San Jacinto in the County of Riverside. The project site is generally located along Ramona Expressway from Sanderson Street to Main Street/Lake Park Drive. 1.2 PREFERRED PROJECT The City of San Jacinto is undertaking the Ramona Expressway Widening Project within the City limits. The portion of Ramona Expressway from State Street east is not designated as State Route 79 (SR-79)but as a local roadway within the City.No portion of SR-79 through the City of San Jacinto has been designated as a scenic route or is identified as being eligible for inclusion in the State Scenic Highway System(State of California 2004).None of these scenic vistas is negatively affected as a result of the proposed expansion of Ramona Expressway since the widening will occur within existing City right-of-way,which has been designated in the City's General Plan for the widening of Ramona Expressway. In addition,Ramona Expressway is an existing major arterial serving the communities of Perris, San Jacinto,Hemet,and the mountain communities in the region and will not have an adverse significant effect on a scenic vista. The proposed project site is the segment of the Ramona Expressway between Sanderson Avenue and Lake Park Drive. Overall,the proposed project consists of widening of Ramona Expressway, including pavement widening with new curb/gutter,and related drainage and infrastructure improvements.No acquisition of right-of-way is anticipated. The project site is located in Sections 17,20,29, and 32,Township 4 South,Range 1 West as shown on the U.S. Geological Survey (USGS)Lakeview, California and San Jacinto, California 7.5-minute series topographic maps. The proposed project is divided into two phases: Sanderson Avenue to Eagle Road,and Eagle Road to Main Street/Lake Park Drive. 1.2.1 Phase I: From Sanderson Avenue to Eagle Road Phase I of the Ramona Expressway widening project consists of improving the roadway segment from a total of four lanes to a total of six lanes between Sanderson Avenue and Eagle Road (Figure 1). This phase also consists of pavement widening with new curb/gutter on both sides of centerline and concrete sidewalk on both sides.The widening will create three lanes of traffic in either direction, a center left-turn pocket or landscaped median and minimal drainage improvements. The improvements will include adjustment and relocation of existing traffic signal poles.

DETERMINATION OF BIOLOGICALLY EQUIVALENT OR SUPERIOR PRESERVATION NOVEMBER 2011 RAMONA EXPRESSWAY WIDENING CITY OF SAN JACINTO 1.2.2 Phase I1: From Eagle Road to Main Street/Lake Park Drive This phase consists of the segment from Eagle Road to Main Street/Lake Park Drive with widening from total of two lanes to a total of four lanes (Figure 2).The project includes pavement widening to provide for minimum of two lanes of traffic in each direction,one left-turn pocket or striped median including 5 to 8 feet of paved shoulder,and minimal drainage improvements. This project will also include adjustment and relocation of existing traffic signal poles. 1.3 WHY THE AVOIDANCE ALTERNATIVE IS NOT FEASIBLE The current project is designed to minimize impacts to adjacent land as much as possible.The road will be widened along one side of the existing pavement in a narrow wedge to merge with the existing four-lane roadbed at the newly constructed interchange of Ramona Expressway and Lake Park Drive. Refer to Figure 3 for a map showing the area for the new pavement and road shoulder. The Avoidance Alternative would actually be no construction. The existing road cannot accommodate additional lanes within the existing footprint.The No Project Alternative would maintain the current configuration of Ramona Expressway in the project area. Under this alternative,there would be no additional lanes. Though smaller, localized projects could be considered,approved, and implemented on their own merits, future major corridor improvements to Ramona Expressway would eventually be implemented as part of the County of Riverside Mid County Parkway (MCP)project.

The small mammal habitat assessment,trapping survey, and DBESP are limited to the MSHCP designated mammal survey area.Refer to previously referenced Figure 3 for map of the survey area. The MSHCP small mammal survey area is 4,250 linear feet north of the Ramona Expressway and Lake Park Drive intersection. 2.1.2 Field Reconnaissance and Focused Surveys Literature review, field surveys, focused surveys, and reports were completed in order to assess potential project impacts to natural resources within the project. Several biological surveys were conducted.The table below summarizes the biological studies.

Erickson, M.McKeman 2.1.3 Vegetation Mapping The vegetation, land use, and soils maps are included in the MSHCP Consistency Report.In the MSHCP Mammal Survey Area,the vegetation adjacent to the road is agricultural fields, non-native annual grassland, and California buckwheat scrub on the slopes at the Main Street/Lake Park Drive interchange. Within the right-of-way and the proposed project area,the ground is barren or the vegetation is non-native annual grasses and forbs.For views of existing site conditions, refer to site photos and to the table of plant species observed that are provided in the burrowing owl focused survey report. RATLK1002_Ramona Exp\Bio\MSHCP DBESP JPR\DBESP_fina1_AH_Ciry.doc(11/3/2011) 9 LSA ASSOCIATES. INC. DETERMINATION OF BIOLOGICALLY EQUIVALENT OE SUPERIOR PRESERVATION NOVEMBER 0011 RAMONA EXPRESSWAY WIDENING CITY OF SAN JACINTO 2.2 EXISTING CONDITIONS 2.2.1 Environmental Setting The small mammal survey area is in the southern portion of the City of San Jacinto. The land uses surrounding the project site are agricultural or open space managed by the Eastern Municipal Water District and the Riverside County Flood Control and Water Conservation District. 2.2.2 On-Site Land Uses The small mammal survey area is centered on the Ramona Expressway right-of-way. It includes the road, road shoulder, and the vacant disturbed land within the parallel fences. 2.2.3 Soils The soils within the small mammal survey area are as mapped by the Natural Resources Conservation Service(MRCS)as Dello (DpB)and Riverwash (RsC)(Soil Survey for Western Riverside Area, California,A.A. Knecht 1971). Refer to Figure 3, Sheet 3 of the MSHCP Consistency Report for map of soil types. 2.2.4 Topography and Hydrology The site elevation ranges from approximately 1,500 to 1,600 feet above mean sea level. The site is generally flat and level. 2.3 MAMMAL SPECIES 2.3.1 Habitat The soils adjacent to the Ramona Expressway are sandy alluvium or sandy loam. Most of the soils within the right-of-way (survey area)have been compacted by imported gravel used to construct the roadbed and to stabilize the road shoulder. Adjacent to the right-of-way are vacant parcels,cultivated fields,or flood control features. Only the slopes of the elevated Lake Park Drive interchange are covered by native coastal sage scrub dominated by California buckwheat(Eriogonum fasciculaturn). The land within the right-of-way is regularly maintained but non-native plants,such as Russian thistle (Salsola sp.), are sheltered in the fence rows. The road shoulder is typically kept clear of vegetation, mowed, or with sparse low growing annual grasses and forbs. 2.3.2 Wildlife Species Functions and Values Assessment The project is located in an MSHCP survey area for San Bernardino kangaroo rat(Dipodomys merriaml parvus)(SBKR)and LAPM due to close proximity to known occupied habitat in the San Jacinto River floodplain. Detailed species life history can be found in the MSHCP Table 9-2 Species Conservation Summary(http://www.rctlma.org/mshcp/volume2/mammals.htmi).The SBKR is found in intermediate and mature alluvial scrub, sage scrub,and chaparral with open ground and minimal invasive species. It is found in sandy loam soils types under alluvial processes such as washes, R:TLK1002_Ramona Exp\BioWSHCP DEESP JPRIDBESP_fna1_AH_Ciry.doc(11/3/2011) 10 LSA ASSOCIATES, INC. DETERMINATION OF BIOLOGICALLY EQUIVALENT OR SUPERIOR PRESERVATION NOVEMBER 2011 RAMONA EXPRESSWAY WIDENING CITY OF SAN JACINTO riverbeds,and floodplains.In contrast,according to the MSHCP Biological Monitoring Program Los Angeles Pocket Mouse Survey Report 2010 dated April 21, 2011, the LAPM is found in sandy loam at lower elevation grassland, alluvial sage scrub, and coastal sage scrub with very low percentage of aerial cover(less than 20%) and mostly bare ground(greater than 50%). The project study area is potentially suitable habitat for and was found to be occupied by LAPM on both sides of the road by the trapping survey conducted by LSA in July 2011. 2.3.3. Ecological Processes Functions and Values Assessment On a regional planning basis, road shoulders and rights-of-way are not an ideal location to target for habitat conservation; nevertheless,areas currently occupied by LAPM should be avoided to the greatest extent possible to maintain existing populations.For conservation planning purposes, however, blocks of habitat that are contiguous with conserved lands and known occupied habitat areas are a better option for resources planning and Covered Species conservation. The land to the east side of the Ramona Expressway study area is owned by public service agencies, the Eastern Municipal Water District and the Riverside County Flood Control District. The land to the west is owned by private commercial corporations. Currently,the parcels are all open and undeveloped but are disked for cultivation or to reduce fire risk. The value of the area will remain moderate to high as suitable habitat for the LAPM,if the land uses remain unchanged in order to maintain the same soil and vegetative characteristics. RATLK1002 Ramona Exp,Bi&NSHCP DBESP JPRIDBESP_final AH_City.dw(113/2011) 11 3.0 UNAVOIDABLE IMPACTS TO LAPM HABITAT 3.1 DIRECT EFFECTS The project will permanently affect 2.2 acres with construction of new road shoulder and pavement. Temporary impacts will include construction vehicle traffic and staging of materials within the right- of-way.Permanent impacts will involve the surrounding work area within the right-of-way along the east road shoulder for a distance of 3,000 linear feet and 2.2 acres. Any LAPM in the permanent and temporary work areas could potentially be harmed during construction. 3.2 INDIRECT EFFECTS The LAPM in the adjacent areas could be affected by disturbances from construction activity due to increased vehicle traffic and human presence. Vehicle noise and fumes, litter,and lighting will cause some indirect effects in the adjacent habitat areas.Animal movement across the road will be restricted because of installation of temporary small mammal exclusionary fence along both right-of-way boundaries. 3.3 RATIONALE WHY AVOIDANCE ALTERNATIVE IS NOT POSSIBLE The lane widening is limited to a sliver of new pavement along the northbound lane or the east side of Ramona Expressway. Construction work will not be required along the southbound lane/west side of the road. The No-Build alternative only postpones the impacts to LAPM habitat since the road will eventually be widened through a County road improvement project.An alternative design to widen the road on both sides of the existing roadbed would likely cause more ground disturbance than restricting the work to one side.

The Geller property was acquired by the RCA to conserve occupied habitat for the LAPM. Other small mammal MSHCP Covered Species present on the mitigation site area include the Aguanga kangaroo rat (Dipodomys inerriami collinus) and the Dulzura kangaroo rat(Dipodomys simulans).The City of Jacinto will compensate the RCA for the 2.2-acre portion of the land purchase price of the 40-acre parcel(APN 583-180-001). The Geller#3 property is located at Temecula Creek southwest of the intersection of SR-79 and SR- 371 in Aguanga,California(Figure 4).The property is mapped within unsectioned lands in Township 8 South,Range 1 East on the USGS Aguanga, California 7.5-minute quadrangle map or latitude 33.438655'and longitude-116.871272°. 4.1.2 Construction Avoidance and Minimization Measures Biological mitigation measures for small mammals and other species of concern are listed below. These measures were previously presented in the draft initial study/mitigated negative declaration (IS/MND)prepared by LSA(April 5,2011). BIO-01 All vegetation clearing, tree removal activities,or tree trimming activities shall occur outside of the nesting bird season (February 15—August 31). In the event that vegetation clearing is necessary during the nesting season, a qualified biologist shall conduct a pre- construction survey to identify the locations of nests. Should nesting birds be found,the biologist shall establish an exclusionary buffer.This buffer shall be clearly marked in the field by construction personnel under guidance of the biologist, and construction or clearing shall not be conducted within this zone until the biologist determines that the young have fledged or the nest is no longer active. BIO-02 Trenches and holes shall be inspected for entrapped wildlife each morning prior to the onset of construction.Holes and trenches shall be thoroughly inspected by qualified permitted biologist for entrapped animals prior to the holes and trenches being filled.Any animals discovered shall be removed from the trench or hole by a qualified biologist and released. BIO-03 A pre-construction burrowing owl survey shall be conducted by a qualified biologist within 30 days prior to ground-disturbing activities for each phase of construction in order to determine whether any burrowing owls are occupying potentially suitable desert scrub habitat. If surveys determine that burrowing owls occupy the site, a burrowing owl mitigation plan shall be prepared, subject to approval by the California Department of Fish and Game(CDFG). Mitigation measures identified in the plan shall include: R:\TLK1002_Ramona Exp\Bio\MSHCP DBESP.iPR\DBESP,final AH,City.ilm(I1 3.='2011) 13 i r T ` 74 215 7' S 15 'k' K r 76 77 , AAA A. n N _ �`�.•,� / 'r' -r" O...z 71P M 4 •1�1{�Jp Jay ,, y y � �y- _ 4 '•!� `� }`♦ R� YY 14s Yam.

DETERMINATION OF BIOLOGICALLY EQUIVALENT OR SUPERIOR PRESERVATION NOVEMBER 2011 RAMONA EXPRESSWAY WIDENING CITY OF SAN JACINTO Burrows located outside the project area(within 250 feet) shall be flagged for avoidance. Unoccupied burrows located in the project area shall be covered to prevent owls from reoccupying the burrows prior to construction. If active owl burrows are discovered within 250 feet of proposed work areas,the owls shall be relocated from the burrows using either active or passive techniques as recommended by the CDFG. Owl relocation, as well as discouragement of owls from returning to the site, shall occur in the following manner: 1) During the non-breeding season(September I through January 31),burrowing owls occupying proposed work areas shall be evicted by passive relocation. Passive relocation shall include the installation of one-way doors on burrow entrance. Any active burrow shall be replaced off-site in adjacent habitat with an artificial burrow. Burrows shall be inspected with a fiber optic camera to ensure animals do not remain in the den. 2) If construction is scheduled during the breeding season(February 1 through August 31) and prior to the relocation of the owls,a 250-foot protective buffer shall be maintained around burrows occupied by owls until the young have fledged. Other actions could include passive relocation if it is determined that owls have not begun laying eggs or postponement of construction in the area until the young are fledged and no longer dependent upon the nest burrow. 3) Once fledglings are capable of independent survival and adult non-breeding owls have successfully been relocated off site,potential owl burrows shall be collapsed in order to keep the owls from returning. BIO-04 Trapping shall be conducted for MSHCP small mammal survey species within 30 days prior to ground-disturbing activities associated with the project. Trapping shall be conducted by a permitted biologist using standard protocol measures associated with SBKR, LAPM,and other sensitive mammal species.The area within the exclusionary fence shall be trapped for a maximum of 8 nights and any trapped animals shall be relocated to suitable habitat outside the fenced construction limits in previously constructed artificial burrows. BIO-05 Prior to project construction, a 4-foot high, and 0.5-inch temporary steel mesh small mammal exclusionary fence shall be placed along the right-of-way limits where suitable LAPM habitat exists, as determined by a qualified permitted biologist. The bottom of the exclusionary fence shall be buried belowground a minimum depth of 12 inches to minimize the potential that LAPM can re-enter the construction area and to preclude impacts to adjacent habitat. BIO-06 The temporary small mammal exclusionary fence shall be maintained in place throughout the duration of construction in these areas to minimize take of LAPM during the construction phase and preclude the inadvertent disturbance of outlying areas by construction personnel. Access to LAPM habitat outside of the construction limits shall be prohibited and posted accordingly. Because LAPM are nocturnal,the exclusionary fence shall be inspected daily by qualified permitted biologist before dusk and shall be repaired as necessary so that there are no gaps greater than 0.5 inch on any portion of the fence that could allow LAPM entry into the project area.

DETERMINATION OF BIOLOGICALLY EQUIVALENT OR SUPERIOR PRESERVATION NOVEMBER 2011 RAMONA EXPRESSWAY WIDENING CITY OF SAN JACINTO BIO-07 Within construction limits in any potentially suitable habitat for LAPM in or adjacent to San Jacinto River,the construction contractor shall ensure that all excavated,steep- walled holes or trenches more than 2 feet deep are covered at the close of each working day with plywood or provide one or more escape ramps constructed of earth fill or wooden planks to prevent entrapment of LAPM during construction. The ramps shall be located at no greater than 100-foot intervals,with slopes less than 45 percent, and be at least 1 foot in width. BIO-08 All construction pipes,poles, culverts, or similar structures with a diameter of 1.5 inch or greater stored at a construction for one or more overnight periods shall be thoroughly inspected by qualified permitted biologist for the presence of LAPM before the pipe is subsequently buried,capped, or otherwise used or moved in any way.Unburied pipes laid in trenches overnight shall be capped. If LAPM are discovered inside a pipe,the section of pipe where the LAPM is discovered shall not be moved until a qualified biologist has been consulted.If necessary and under the direct supervision of a qualified biologist, the pipe may be moved only once to remove it from the path of construction activity until the animal has been removed and released. BIO-09 A qualified biological monitor shall be present during ground-disturbing activities within suitable habitat for LAPM. The monitor shall have the authority to stop activities should it be required to avoid take of the species.The monitor shall also be responsible for ensuring the project is in compliance with conditions set forth by the USFWS in the incidental take authorization for LAPM pursuant to the MSHCP. 4.2 MITIGATION FOR INDIRECT EFFECTS The following mitigation measures are provided for project compliance with MSHCP compliance guidelines for covered transportation projects located within criteria cells and adjacent to public/ quasi-public land and existing Conserved Area. 4.2.1 Urban/Wildlands Interface Analysis 4.2.1.1: Drainage.All runoff from the new paved areas will be directed into storm drains. A Storm Water Pollution Prevention Plan(SWPPP)will be prepared to satisfy National Pollutant Discharge Elimination System(NPDES)requirements. Construction erosion control best management practices (BMPs)to be implemented include preserving existing vegetation when feasible,temporary erosion control per California Stormwater BMPs Handbook, seeding inactive areas immediately, and application of permanent erosion construction upon completion of construction. More information can be obtained from the SWPPP prepared by TriLake Consulting Engineers.BMPS listed in the IS/MND Section 3.0 Environmental Checklist include hydroseeding, check dams,gravel bags,silt fences,soil binders,and hay bails. Prior to issuance of grading permits, the City will submit a Notice of Intent and obtain a waste discharge identification number from Santa Ana Regional Water Quality Control Board(RWQCB). 4.2.1.2: Toxics.Expected and potential pollutants from the road and vehicles are sediment,petroleum products, and trace metals (e.g., zinc,copper, lead,cadmium, and iron). Vehicle repair will occur off RATLK10023amonE Exp\Bio\1MSHCP DBESP JPRTBESP_final_AH_City.doc(11/3/2011) 16 LEA ASSOCIATES, INC. DETERMINATION OF BIOLOGICALLY EQUIVALENT OR SUPERIOR PRESERVATION NOVEMBER 2011 RAMONA EXPRESSWAY WIDENING CITY OF SAN JACINTO site or in designated separate maintenance areas located away from roadside ditches and storm drains. Drip pans and spill kits will be used in the construction site and staging areas. 4.2.1.3: Lighting.The project will not direct light sources toward the San Jacinto River or adjacent open space during construction. 4.2.1.4: Noise.A noise study for the project has been conducted as part of the IS/MND.The proposed project is not expected to result in noise levels above the current noise level standards. Equipment will be operated and maintained to attenuate noise.For example,no idling of unused vehicles will be allowed, securing loose loads and equipment will be required,and noise attenuators'will be installed on construction equipment. 4.2.1.5: Invasive Species.MSHCP Table 6-2 contains a list of plants to be avoided adjacent to the MSHCP Conservation Area. For portions of the project that are adjacent to the San Jacinto River. These species will not be part of the project design approved by the City. Any of these undesirable plants in the existing landscaping will be removed,wherever possible,and replaced with native and drought-tolerant plants that are consistent with the MSHCP. 4.2.1.6: Barriers. The proposed project would not create new means of accessing adjacent natural areas and would reduce vehicular access to such areas by eastward extension of curb and gutter and an asphalt concrete berm. Prior to construction,a temporary exclusionary fence will be installed between the work area and natural areas to be avoided. 4.2.1.7: Grading/Land Development.Manufactured slopes associated with proposed site development will not to extend into the MSHCP Conservation Area associated with the San Jacinto River.All grading will be limited to project construction area in the existing right-of-way. Erosion-control measures include leaving existing vegetation in place where feasible,use of temporary erosion control measures at regular intervals throughout the rainy season,stabilizing non- active areas, and use of designated entry points, tire wash stations, street vacuuming, dust suppression,silt fencing, sandbags, gravel bag berms, erosion-control blankets,hydroseeding using native plant species, and swales in concentrated flow areas.Permanent erosion-control measures will be installed as part of completion of construction. 4.2.2 Construction Guidelines and Best Management Practices The MSHCP(Volume I, Section 7.5.1)provides construction guidelines and BMPs (MSHCP Appendix C)applicable to planned roads, including the proposed project,within the Criteria Area. These include the following: • Water pollution and erosion control plans will be prepared in accordance with Santa Ana Regional Water Quality Control Board(RWQCB)requirements.The plans will include sediment RATLK1002_Ramona ExplBio\MSHCP DBESP JPRIDBESP_5na1_AH_City.doc(1113/2011) 17 LSA ASSOCIATES, INC. DETERMINATION OF BIOLOGICALLY EQUIVALENT OR SUPERIOR PRESERVATION NOVEMBER 2011 RAMONA EXPRESSWAY WIDENING CITY OF SAN JACINTO and hazardous material control measures, and describe dewatering process and diversion structures,fueling and equipment management practices, and plant materials used for erosion control. • The project footprint and access routes will be minimized. Limits of ground disturbance will be clearly defined in the field and verified by project biologist prior to start of work. Construction limits shall be fenced with orange snow screen and maintained until completion of the project. • Water will be used in construction areas to control dust. • Short-term diversion of drainages associated with road culverts will be accomplished by the use of sandbags and other minimal impact methods. • Silt fencing and other sediment trapping materials will be used down-slope of construction activities. • Precautions shall be taken to prevent the release of cement and other toxic substances into sensitive habitat. • Settling ponds will be constructed and regularly maintained to prevent any sediment from entering drainage culverts and the San Jacinto River. • No material will be deposited into water courses. • No trash or debris or stockpiling shall be deposited outside the Area of Direct Effects (ADE). • Equipment storage,fueling, and staging will be sited in non-sensitive upland areas that have minimal risk to discharge to sensitive habitat areas and streams. • Fueling and equipment maintenance and storage of hazardous materials will occur only in a designated area within the grading limits that contains runoff,all spills must be cleaned up and disposed of properly and reported to City of San Jacinto. • No equipment is to be placed in stream bed or bank. • Exotic species removed during construction will be properly disposed of to prevent regrowth and spreading. • Temporary impact areas will be returned to pre-existing contours and planted with locally adapted native species. • Avoid attracting predators or species(e.g.,starlings, cowbirds,crows,ravens,raccoons; and exotic species,such as domestic pets)that displace species of concern to project site and the natural habitat areas. • Construction personnel will receive environmental awareness training from a qualified biologist. • Monitoring and reporting on compliance with avoidance and minimization measures and other BMPs will occur over the duration of the construction activity. • Firefighting equipment will be available on site. • The Permittee(City of San Jacinto)shall have the right to access and inspect the project for compliance with project approval conditions. • Night lighting shall be directed away from habitat areas.

DETERMINATION OF BIOLOGICALLY EQUIVALENT OR SUPERIOR PRESERVATION NOVEMBER 2011 RAMONA EXPRESSWAY WIDENING CITY OF SAN JACINTO • A qualified biologist will lead tailgate meetings to train construction personnel to recognize species and habitats of concern and familiarize them with applicable environmental regulations. • Water pollution and erosion control plans will be followed per RWQCB requirements. • Project footprint and access routes will be minimized to greatest extent possible. • Project limits marked in the field by an exclusionary fence and the placement will be reviewed by the project biologist. • Avoid placing of equipment,materials, and personnel in streambeds and adjacent upland habitats. • Avoid work in riparian areas during active breeding season;typically designated as February I through August 31 by the CDFG. Disturbance is restricted to a minimum of 300 feet away from any active least Bell's vireo nest. • If vegetation removal must occur during this avoidance period,then a nest survey by a qualified biologist is required. The nest survey shall be conducted for five consecutive days and no more than three days prior to clearing. If an active nest is observed, then the nest location shall be fenced off surrounding a minimum 300-foot(500 feet for raptors) radius buffer zone. The buffer zone shall not be disturbed until the nest is inactive. • Stream diversions will be conducted using standard construction protocol acceptable to RWQCB. • Hazardous materials, equipment repair,and fueling will occur in designated safe areas and all spills must be cleaned up and disposed of properly and reported to City of San Jacinto. • There is to be no erodible fill or stockpiling of debris in streambeds or banks. • Biological monitoring will occur during vegetation removal activities. • Temporary impacts are to be minimized to the greatest extent practicable and all temporary impact areas are to be returned to pre-existing contours and revegetated with native plants. • Exotic plants are to be removed from the project site. • The project site will be kept clean of food-related items. 4.3 MAINTENANCE AND MONITORING PROGRAM The land acquired for mitigation of impacts to LAPM will be under the management of the RCA and Riverside County Parks and Open Space District(District). The RCA and District maintain the Reserve as necessary to meet Covered Species conservation goals. The County of Riverside may elect to monitor the LAPM population on this property as part of the Biological Monitoring Program established as part of the MSHCP. Typically,trapping surveys are conducted every three years. R:\TLK1002_Ramona Exp\Bio\MSHCP DBESP JPRIDBESP_final_AH_Ciry.doc(i 1/3/2011) 19 5.0 DETERMINATION OF BIOLOGICALLY EQUIVALENT OR SUPERIOR PRESERVATION The road widening project planned by the City of San Jacinto will affect 2.2 acres within the existing Ramona Expressway right-of-way.The project is part of the County of Riverside adopted Circulation Element and Covered Activity under the MSHCP. This segment of the road widening project was found to be occupied by the Los Angles pocket mouse(LAPM). The City of San Jacinto investigated on-site mitigation options but found that there is no opportunity to purchase or dedicate an easement for purpose of habitat conservation adjacent to Ramona Expressway.Nevertheless,the superior preservation proposed for the road widening project is reimbursement of the purchase price($14,629 per acre)for a 2.2-acre portion of 40-acre parcel, known as the Geller property. The property is identified as Geller#3 (APN 583-180-001), is located in an undeveloped reach of the Temecula Creek floodplain, and is also known to be occupied by LAPM. The Geller#3 property is superior to the impact area due to known presence of LAPM and its adjacency to extensive occupied habitat areas. The Geller property is superior to the proposed project site since the parcel is not within a road right-of-way and is not frequently disturbed by vehicle traffic and human activity. The suitable habitat areas adjacent to the road widening project are privately owned agricultural land, or land held by County flood control and the East Valley Water District. Also, the Geller property is contiguous with other Regional Conservation Authority(RCA)acquired MSHCP Conserved Lands within the REMAP Area Plan. The"purchase price mitigation credit"will release funds to the RCA to manage and acquire additional Conservation Land.Thus, the City of San Jacinto will support RCA's purpose of meeting the goals and objectives of the MSHCP.

Applicable Com'Linkage: Proposed Core 5 Area Plan: San Jacinto Valle APN Sub-Unit Cell Group Cell Various SU 3-Upper San Jacinto Z 2893 RiverlBaustista Creek 3098 3099 Project Characteristics a. The proposed project consists of the widening of the Ramona Expressway. between Sanderson Avenue and Lake Park Drive, in the City of San Jacinto, Riverside County, California. The proposed project includes pavement widening with new curb and gutter, and related drainage and infrastructure improvements. No acquisition of right-of-way is anticipated with the proposed project. The proposed project will be divided into 2 phases. Phase I of the proposed project will consist of improving the roadway segment from a total of 4 lanes to a total of 6 lanes between Sanderson Avenue and Eagle Road and will consists of pavement widening with new curb and gutter on both sides of the centerline and concrete sidewalk on both sides. The widening of project will create 3 lanes of traffic in either direction, a center left-turn pocket or landscaped median, minimal drainage improvements, and adjustment and relocation of existing traffic signal poles. Phase II of the proposed project will consist of widening the segment from Eagle Road to Main Street/Lake Park Drive from 2 lanes to 4 lanes. Phase II is within Criteria Cells and is therefore subject to this JPR review. Phase II of the proposed project also includes pavement widening to provide for minimum of 2 lanes of traffic in each direction, 1 left-turn pocket or striped median including 5 to 8 feet of paved shoulder, minimal drainage improvements, and adjustment and relocation of existing traffic signal poles. Relation to Reserve Assembly and Covered Activity Status b. The Ramona Expressway Widening Project between Sanderson Avenue and Lake Park Drive is depicted on Figure 7-1 of the MSHCP, which depicts the roadways that were contemplated in the MSHCP as going through the Criteria Area per Section 7.3.5 of the MSHCP. The project is considered a Covered Activity 1 of 5 RCA Joint Project Review (JPR) egional PUBLIC PROJECT OWconservation JPR#: 11-06-16-02 uthority Date: 11-17-11 tern Riverside County since it is depicted on Figure 7-1 of the MSHCP. Since the project is a covered activity, it is not subject to the Criteria. c. As stated in Section 3.2.3 of the MSHCP, the Reserve Features associated with the project impact area are Proposed Core 5. Proposed Core 5 is comprised of the portion of the upper San Jacinto River extending from the San Jacinto Mountains to just west of State Street. It is contiguous with Core Areas in the San Jacinto Mountains and areas downstream along the San Jacinto River. Planning Species for which Habitat is provided within this Core include mountain yellow-legged frog, arroyo toad, least Bell's vireo, southwestern willow flycatcher, San Bernardino kangaroo rat, and Los Angeles pocket mouse. Maintenance of floodplain processes and water quality of the San Jacinto River is important for these species, as well as maintenance of habitat quality. This Core likely provides for movement of mammals such as mountain lion and bobcat, connecting to Core Areas in the San Jacinto Mountains, Lake Perris and San Jacinto Wildlife Refuge. Flood control activities resulting from adjacent planned land uses may also adversely affect species such as arroyo toad, San Bernardino kangaroo rat, least Bell's vireo, southwestern willow flycatcher and Los Angeles pocket mouse. d. The Planning Species for Proposed Core 5 are arroyo toad, mountain yellow-legged frog, Cooper's hawk, yellow warbler, southwestern willow flycatcher, least Bell's vireo, San Bernardino kangaroo rat, bobcat, mountain lion, slender-horned spine flower, and western pond turtle. e. The site is located within Cell Group Z. As stated in Section 3.3.13 of the MSHCP, Conservation within Cell Group Z will contribute to assembly of Proposed Core 5. Conservation within Cell Group Z will focus on grassland habitat. Areas conserved within Cell Group Z will be connected to grassland habitat proposed for conservation in Cell 3098 to the west and Cell 3204 to the south. Conservation within Cell Group Z will be approximately 5% of the Cell Group focusing in the southwestern portion of the Cell Group. f. Rough Step: The proposed project is within Rough Step Unit 3. Rough Step Unit 3 encompasses 150,086 acres within the north-central portion of western Riverside County. Rough Step Unit 3 includes Lake Perris, the San Jacinto Wildlife Area, the San Jacinto River, and the Lakeview Mountains. Rough Step 3 is bounded by Interstate 215 to the west, a branch of the San Jacinto River to the northeast, State Route 60 to the north, and Newport Road, Olive Avenue, and Stetson Avenue to the south. There are 32.43 acres within the Criteria Area of Rough Step 3. Key vegetation communities within Rough Step 3 include coastal sage scrub; grasslands; playas and vernal pools; riparian scrub, woodland, forest; and Riversidean alluvial fan sage scrub. In 2010, all vegetation categories are "in" rough step; therefore, development of the project will not result in any vegetation categories to be "out" of rough step. g. The project alignment does cross areas that are contemplated for MSHCP Conservation associated with Proposed Core 5. The project is a Covered Road and will widen the existing road and improvements within existing right-of-way, As such, the project would not adversely affect the ability of the MSHCP Conservation Area to be assembled or managed in accordance with the MSHCP. 2of5 RCA Joint Project Review (JPR) egional PUBLIC PROJECT Conservation JPR#: 11-06-16-02 Authority Date: l l-17-11 Western Riverside County h. Project information was provided by the Permittee, as well as a Biological Resources Assessment and MSHCP Consistency Report dated January 26, 2010, by LSA, Initial Study/Mitigated Negative Declaration dated April 5, 2011 provided by LSA, Response to IS/MND for the Ramona Expressway Widening Project by LSA dated June 14, 2011 provided by LSA, Burrowing Owl focused survey dated June 14, 2010 by LSA, Result of San Bernardino kangaroo rat and Los Angeles Pocket Mouse Trapping report dated August 19, 2011 by LSA, and Determination of Biologically Equivalent or Superior Preservation (DBESP) for LAPM dated November 3, 2011 by LSA. Section 7.5 of the MSHCP addresses the Guidelines for Facilities within the Criteria Area and Public/Quasi Public Lands. The proposed project has or will implement the conditions set forth in Section 7.5.1 through the design process, or will through the implementation process. The proposed project is limited to the existing fenced right-of-way. Section 7.5.2 of the MSHCP addresses the guidelines for constructing wildlife crossings. The project limits of disturbance is limited to areas within the existing right of way, therefore impacts are not expected within Proposed Core 5. The project will also be designed to be consistent and compliant with Section 7.5.3 of the MSHCP, which addresses the Best Management Practices (BMPs) that will be used to minimize impacts to habitats and species. Within the Criteria Cells, LSA reports that the project will minimize any removal of vegetation remaining within the right-of-way that is outside the actual construction site and will avoid using grass-covered land for staging or parking that is outside of the right-of-way and within the proposed Conservation Area. i. Since the road widening project is depicted on Figure 7-1 of the MSHCP, the project is considered a Covered Activity. Additionally, since the project has considered its impacts on wildlife movement, planning species, ecotones, and habitats, it will not adversely affect Reserve Assembly. Other Plan Requirements Data: Section 6.1.2—Riparian/RiverineNemal Pool Mapping: Yes. The project alignment is not located within riparian/riverine areas. There are no vernal pool and fairy shrimp habitat within the project footprint. Section 6.1.3 —Narrow Endemic Plant Species Surveys: No. The project alignment is not located within a Narrow Endemic Plant Species Survey Area(NEPSSA). Section 6.3.2—Additional Species Surveys: Yes. The project alignment is not located within a Criteria Area Species Survey Area (CASSA). However, the project alignment is located within an Additional Species Survey area for burrowing owl, Los Angeles pocket mouse, and San Bernardino kangaroo rat. 3of5 RCA Joint Project Review (JPR) egional PUBLIC PROJECT onservation JPR#: 11-06-16-02 Authority Date: 11-17-11 Western Riverside County Section 6.1.4—Urban/Wildland Interface Guidelines: Yes. The project is located adjacent to proposed MSHCP Conservation Areas and is subject to Urban/Wildland Interface requirements. Other Plan Requirement Comments: a. Section 6.1.2: Based on the Biological Resources Assessment and MSHCP Consistency Report prepared by LSA dated January 26, 2010, the project alignment does not support riverine/`riparian habitat. LSA reports that the site lies entirely within the existing right-of-way. Soils within the project footprint include saline-alkali, loamy fine sand, gravelly substratum, loamy sand, fine sandy loam, loamy substratum, and riverwash, LSA reports no vernal pools present within the project footprint therefore no surveys for listed fairy shrimp species were required. Based on the information provided by LSA, the project demonstrates compliance with Section 6.1.2 of the MSHCP. b. Section 6.3.2: The proposed project is located within an Additional Species Survey area for burrowing owl, Los Angeles pocket mouse (LAPM), and San Bernardino kangaroo rat (SBKR). A wintering owl was present in the right-of-way between Sanderson Avenue and Potter Road during the previously conducted habitat suitability assessment survey in December 2009. LSA Associates (LSA) conducted another habitat suitability assessment survey on May 18, 2011 and focused surveys were conducted on May 26, 27, 28, and 29, 2011. No burrowing owls or owl signs were observed during the time of the focused surveys. Additionally, the proposed project is located within LAPM and SBKR survey area. LSA conducted live trapping for 5 consecutive nights during the week of July 10, 2011 to determine presence/absence of LAPM and SBKR. No SBKR were captured during the live trappings; however, 24 LAPM were captured during the trapping effort of which two were determined to be in a reproductive state. LSA reported that many of these LAPM captures were the same individual, but none of the animals were marked prior to release. LSA reports that the proposed new pavement and road shoulder will impact 2.2 acres of the 6.5 acres of unpaved ground within the segment of the Ramon Expressway right-of-way within the MSHCP Mammal Survey Area. Since the project does not demonstrate that 90% of the portions of the project alignment that provide for long-term conservation value for LAPM are avoided, a DBESP was prepared by LSA dated November 3, 2011. The DBESP notes that mitigation for permanent impacts to occupied LAPM habitat will be through payment of funds to the RCA to apply to a conservation land acquisition (Geller #3, APN: 583-180-001) at a mitigation ratio of 1:1 (2.2 acres). The Geller #3 property is known to have occupied LAPM and over 20 acres of suitable habitat. The Geller #3 property is located in Temecula Creek and is about 40-acres in size. The City of San Jacinto shall contribute funds as determined by the RCA to the RCA prior to the start of site disturbance in order to demonstrate consistency with the MSHCP. Based on the information provided by LSA and the mitigation provided for the 2.2 acres of impacts to LAPM, the project demonstrates compliance with Section 6.3.2 of the MSHCP. 4of5 RCA Joint Project Review (JPR) egional PUBLIC PROJECT onservation JPR#: 11-06-16-02 V Authority Date: 11-17-11 0Wes tern Riverside County c. Section 6.1.4: To preserve the integrity of areas adjacent to the project alignment which are proposed Conservation Areas, the guidelines contained in Section 6.1.4 related to controlling adverse effects for development adjacent to the MSHCP Conservation Area should be considered by the Permittee in their actions relative to the project. Specifically, the Permittee should include as project conditions of approval the following measures: i. Incorporate measures to control the quantity and quality of runoff from the site entering the MSHCP Conservation Area. In particular, measures shall be put in place to avoid discharge of untreated surface runoff from developed and paved areas into MSHCP Conservation Areas. According to the NES, the proposed project will include measures required through the National Pollutant Discharge Elimination System (NPDES) requirements, to ensure that the quality and quality of runoff discharged to MSHCP conservation areas are not altered from the existing conditions. ii. The use chemicals or generation of bioproducts (i.e.) manure, which are potentially toxic or may adversely affect wildlife species, habitat or water quality shall not result in discharge to the MSHCP Conservation Area. The greatest risk is from landscaping fertilization overspray and run-off. iii. Night lighting shall be directed away from the MSHCP Conservation Area to protect species within the MSHCP Conservation Area from direct night lighting. Shielding shall be incorporated in project designs to ensure ambient lighting in the MSHCP Conservation Area is not increased. iv. Proposed noise generating land uses affecting the MSHCP Conservation Area shall incorporate setbacks, berms or walls to minimize the effects of noise on MSHCP Conservation Area resources pursuant to applicable rules, regulations and guidelines related to land use noise standards. v. Consider the invasive, non-native plant species listed in Table 6-2 of the MSHCP in approving landscape plans to avoid the use of invasive species for the portions of the project that are adjacent to the MSHCP Conservation Area. Considerations in reviewing the applicability of this list shall include proximity of planting areas to the MSHCP Conservation Areas, species considered in the planting plans,resources being protected within the MSHCP Conservation Area and their relative sensitivity to invasion, and barriers to plant and seed dispersal, such as walls,topography and other features. vi. Proposed land uses adjacent to the MSHCP Conservation Area shall incorporate barriers, where appropriate in individual project designs to minimize unauthorized public access, domestic animal predation, illegal trespass, or dumping into the MSHCP Conservation Areas. Such barriers may include native landscaping, rocksiboulders, fencing, walls, signage, and/or appropriate mechanisms. Manufactured slopes associated with the proposed site development shall not extend into the MSHCP Conservation Area. ST/SNS l 5of5
