REQUEST: GENERAL PLAN AMENDMENT 05-001 TO ESTABLISH A COLLECTOR ARTERIAL DESIGNATION AND TO RECLASSIFY EL CAMINO REAL BETWEEN FIRST STREET AND NEWPORT AVENUE FROM A SECONDARY ARTERIAL TO A COLLECTOR ARTERIAL. RECOMMENDATION That the Planning Commission: 1. Adopt Resolution No. 3967 recommending that the City Council adopt the Negative Declaration as adequate for General Plan Amendment 05-001; and 2. Adopt Resolution No. 3968 recommending that the City Council approve General Plan Amendment 05-001. Planning Commission Report General Plan Amendment 05-001 April 11, 2005 Page 2 BACKGROUND AND DISCUSSION The Circulation Element is one of the seven General Plan elements mandated by the State of California, as articulated in Sections 65580 to 65589.8 of the Government Code. The proposed project is a General Plan Amendment to the City's Circulation Element to reclassify a street segment of EI Camino Real between First Street and Newport Avenue from a four -lane Secondary Arterial to a two-lane collector roadway. The roadway segment of EI Camino Real has a north -south alignment before it transitions to a northwest -southeast alignment between Sixth Street and Newport Avenue. This portion of EI Camino Real is located within the City's Old Town commercial district, which supports a mixture of retail and commercial uses and includes various public improvements to provide a more pedestrian -oriented environment. In November 1997, the City, in coordination with the Orange County Transportation Authority (OCTA), approved a demonstration project to reduce the number of travel lanes on EI Camino Real between Second Street to Sixth Street (one block south of First Street and west of Newport Avenue) from a four -lane undivided Secondary Arterial street to a two-lane undivided collector street with diagonal parking along both sides of the street. The purpose of the demonstration project was to document the existing and define the future impacts of the redesignation on other nearby streets and intersections. A subsequent traffic study (Appendix B of the Initial Study, which is Exhibit A to Resolution No. 3967) was prepared by WPA/Willdan in May 2001 that concluded 2020 traffic conditions, both with and without the project, would result in acceptable daily traffic levels and intersection operations. Following the success of the demonstration project and the preparation of the traffic study, the OCTA approved an amendment to the Master Plan of Arterial Highways (MPAH) to change the status of the street segment of EI Camino Real between First Street and Newport Avenue from a four -lane secondary arterial to a two-lane local collector roadway. The proposed General Plan Amendment would similarly reflect the two-lane collector status of the roadway on the City's Circulation Element and ensure consistency between the City's General Plan and OCTA's MPAH. The purpose of the proposed amendment to the City's Circulation Element is to: (1) achieve consistency with the MPAH designation, (2) reflect the existing and future traffic levels on the roadway segment, and (3) ensure consistency between the roadway and the adjacent land uses by supporting the pedestrian -friendly character of the Old Town commercial district. The two-lane configuration and on -street diagonal parking are consistent with the revitalization goals for Old Town by contributing to a pedestrian - oriented environment. Planning Commission Report General Plan Amendment 05-001 April 11, 2005 Page 3 Specifically, the General Plan Amendment includes the following: Adds a definition of Collector to the Circulation Plan Adds a cross section of a Collector roadway to Figure C-1, Typical Cross Sections • Amends Figure C-2 to add Collector to the Legend and to redesignate EI Camino Real between First Street and Newport Avenue • Amends Table C-5 to reclassify EI Camino Real south of First Street and EI Camino Real south of Main from Secondary to Collector The proposed General Plan Amendment is included as Exhibit A of Resolution No. 3968). A decision to approve General Plan Amendment 05-001 may be supported by the findings contained in Resolution No. 3968. ENVIRONMENTAL A Negative Declaration has been prepared for this project (Exhibit A of Resolution No. 3967). The attached Initial Study discusses potential impact categories. Based on the Initial Study, there is no substantial evidence that the project may have a significant effect on the environment, and no mitigation measures are proposed. The public comments period for the environmental documents was from March 22, 2005, to April 11, 2005.

PASSED AND ADOPTED by the Planning Commission of the City of Tustin, at a regular meeting on the 11 th day of April, 2005. JOHN NIELSEN Chairperson ELIZABETH A. BINSACK Planning Commission Secretary STATE OF CALIFORNIA ) COUNTY OF ORANGE ) CITY OF TUSTIN ) I, ELIZABETH A. BINSACK, the undersigned, hereby certify that I am the Planning Commission Secretary of the City of Tustin, California; that Resolution No. 3968 was duly passed and adopted at a regular meeting of the Tustin Planning Commission, held on the 11 th day of April, 2005. ELIZABETH A. BINSACK Planning Commission Secretary EXHIBIT A OF RESOLUTION NO. 3968 Secondary: A four -lane undivided roadway, with a typical right-of-way width of 80 feet and a curb -to -curb pavement width of 64 feet. These roadways serve as collectors, distributing traffic between local streets, and major and primary arterials. For the MCAS Tustin Specific Plan, 80 -foot right-of-way was modified to a 92 -foot right-of-way to provide a painted median for two-way left turn lanes and Class H bicycle lanes. Collector: A two-lane undivided roadway, with a minimum righLpf-way width of 66 feet and a minimum curb -to -curb width of 50 feet. The width may be increased to accommodate roadway features such as bicycle lanes, on - street parking,and turn lanes At LOS "C," this road type accommodates up to approximately 10,000 vehicle trips per day. This road functions as a collector facility, however it tends to move traffic between two arterials rather than between local streets it has been added to the City's arterial highway system because it provides network continuity and is regionally significant, and may serve through traffic demand where projected volumes do not warrant a higher classification such as Secondary. The Circulation Element roadway classification system does not include private streets. Private street widths and cross-sections will vary from those described for roadways in this Element. Standard cross-sections represent the obvious and accepted answer to most situations. However, the standard cross-sections do not always provide the best solution to any given need or set of objectives. Reasonable flexibility and variety is provided for in the City's private street standards. Figure C-1 shows schematic cross sections of each category of arterial roadway. These sections represent desirable standards, but variation in right- of-way width and specific road improvements will occur in certain cases due to physical constraints and/or right-of-way limitations. In particular, the median width in eight -lane, six -lane and four -lane roadways will vary according to the area being served and the available right-of-way constraints and turn lane requirements. Hence, any of the arterial classifications may deviate from the standards where physical constraints exist or where preservation of community character dictates special treatment. Bikeway facilities are another factor which affect the specific standards applied for various facilities. The desirable goal for every classified street section is that it carry the designed volume of traffic at the desired level of service. Within this requirement, descriptions of width and facilities are offered as basic guidelines and as noted above, variation in design is expected, depending on CITY OF TUSTIN CIRCULATION ELEMENT GENERAL PLAN 20 April 18, 2005 _1.._ ___ _.s•••,•y_s ��"-?&'t6^'�+RS.;_�;;Rfa:�',L�4ie�3n:dS3n!�?�Etti'tS?ifa:3:�:c'w"frt7?�.riT2`3.1^i�if*J 25i:6"°x�avdeiT:u.7t..7S"i7S:"..sm`�;•t'h+L�w`A..`�iu + 8 -LANE MAJOR AR'T'ERIAL 144' R/W' 60, 6 -LANE MAJOR ARTERIAL 120' R/W S/ PRIMARY ARTERIAL 100' R/W/ 46' -- 36, a' SECONDARY ARTERIAL 92' R/W y » (WITH CLASS II BICYCLE LANES) 40' 40� 32; 0' 1 SECONDARY ARTERIAL 80' R/W SOURCE: Austin -Foust Associates, Inc.

DRAFT INITIAL STUDY MARCH 2005 TUSTINIEL CAMINO GENERAL PLAN AMENDMENT 1.0 INTRODUCTION 1.1 PURPOSE AND SCOPE This Initial Study (IS) is being prepared to analyze the environmental effects of a proposed amendment to the City of Tustin General Plan. The proposed project is to reclassify El Camino Real between First Street and Newport Avenue from a secondary arterial to a collector roadway in the Circulation Element of the General Plan. The proposed reclassification is consistent with a parallel change that has already been made to the County of Orange Master Plan of Arterial Highways (MPAH) and reflects the current conditions of the affected roadway segment. The Circulation Element is one of seven mandated elements of the General Plan and is intended to guide the development of the City of Tustin (City) circulation system in a manner that is compatible with the Land Use and other Elements of the General Plan. The purpose of the Circulation Element is to provide a safe, efficient, and adequate circulation system for the City. To meet this purpose and the requirements of Government Code Section 65302 (b), the Circulation Element addresses the circulation improvements needed to provide adequate capacity for future land uses. Corresponding goals and policies are designed to improve overall circulation in the City and to address circulation issues that concern the City. For highway transportation, the physical attributes involve a network of existing and future roadways defined according to designated roadway types, each with specific design standards. Other modes are defined by appropriate physical attributes (e.g., bicycle trails). The County of Orange MPAH forms part of the Orange County General Plan and designates the arterial system in the Circulation Element of the County General Plan. Defined according to specific arterial functional classification, the MPAH serves to define the intended future road system within the County. Cities within the County are expected to achieve consistency with the MPAH in their individual General Plan Circulation Elements. The purpose of the proposed amendment to the City of Tustin Circulation Element is to: 1) achieve consistency with the MPAH designation, 2) to reflect the existing and future traffic levels on the roadway segment, and 3) to ensure consistency between the roadway and the adjacent land uses by supporting the pedestrian -friendly character of the Old Town commercial district in the City of Tustin. The two lane configuration and on -street diagonal parking is consistent with the revitalization goals for Old Town by contributing to a pedestrian -oriented environment. This Initial Study has evaluated each of the environmental issues contained in the checklist provided in Section 3.0 of this document. 1.2 FINDINGS OF THIS INITIAL STUDY Pursuant to the California Environmental Quality Act (CEQA) and the State CEQA Guidelines, this Initial Study has been prepared to determine whether implementation of the City's proposed General Plan Amendment to the Circulation Element (proposed project) will result in significant PActu330\Final Sent\Section l.doc e01/28/05» 1-1 LSA ASSOCIATES, INC. MARCH 2005 DRAFT INITIAL STUDY TUSTINIEL CAMINO GENERAL PLAN AMENDMENT environmental impacts that would require mitigation or the preparation of an Environmental Impact Report (EIR) if significant impacts cannot be avoided. This Initial Study is based on an Environmental Checklist Form, as suggested in Section 15063 (d)(3) of the State CEQA Guidelines. The completed Form is found in Section 3.0 of this Initial Study. It contains a series of questions about the proposed project for each of the listed environmental areas. The Form is used to evaluate whether or not there are any significant environmental effects associated with implementation of the proposed project and, if there are, whether or not mitigation can be attached to the project to lessen or avoid such impacts. Section 4.0 provides an explanation for each answer indicated on the Form. The Form and accompanying evaluation provide the information and analysis upon which the City may make its determination as to whether or not an EIR must 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 • Agricultural Resources • Air Quality • Biological Resources • Cultural Resources • Geology/Soils • Hazards and Hazardous Materials • Hydrology/Water Quality • Land Use/Planning • Mineral Resources • Noise • Population/Housing • Recreation • Public Services • Transportation/Traffic • Utilities/Service Systems • Mandatory Findings of Significance 1.3 EXISTING DOCUMENTS TO BE INCORPORATED BY REFERENCE Section 15150 of the State CEQA Guidelines permits an environmental document to incorporate by reference other documents that provide relevant data.

DRAFT INITIAL STUDY MARCH 2005 TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT 2.0 PROJECT DESCRIPTION 2.1 PROJECT SITE SETTING The City of Tustin is located in central Orange County and encompasses an area of 11.02 square miles. The City is bound on the south by the Cities of Irvine and Santa Ana, on the north by the unincorporated portions of the County of Orange and the City of Orange, on the west by Jamboree Road, and on the east by unincorporated County territory and the City of Irvine. Tustin is located approximately two miles north of Orange County's John Wayne Airport. There are two freeways that transect the City, the Interstate 5 (I-5) (Santa Ana) freeway dividing the City into north and south and the State Route 55 (SR -55) (Costa Mesa) freeway transecting the western portions of the City. The City has an Old Town commercial area, which is one of the oldest historical commercial areas in Orange County. The proposed project is the reclassification of El Camino Real between First Street and Newport Avenue as shown on Figure 2.1. This segment of El Camino Real is located north of I-5 within the Old Town commercial district. The City is proposing to reclassify this portion of El Camino Real from a four -lane Secondary Arterial to a two-lane Local Collector in the Circulation Element of the City's General Plan. This segment of El Camino Real is currently two lanes with on -street diagonal parking. 2.2 PROPOSED DISCRETIONARY ACTION The proposed discretionary action is the approval of an amendment to the Circulation Element of the City's General Plan by the City Council. The proposed amendment includes text, tables, and map changes to reflect a redesignation from a Secondary Arterial to a Collector Arterial. Specifically, the General Plan Amendment includes the following: • Add a definition of Collector to the Circulation Plan • Add a cross section of a Collector roadway to Figure C-1, Typical Cross Sections • Amend Figure C-2 to add Collector to the Legend and to redesignate El Camino Real between First Street and Newport Avenue • Amend Table C-5 to reclassify El Camino Real south of First Street and El Camino Real south of Main from Secondary to Collector The proposed General Plan Amendment is included as Appendix A of this document.

DRAFT INITIAL STUDY MARCH 2005 TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT 2.3 PROJECT DESCRIPTION The Circulation Element is one of the seven General Plan elements mandated by the State of California, as articulated in Sections 65580 to 65589.8 of the Government Code. The proposed project is a General Plan Amendment to the City's Circulation Element to reclassify a street segment of El Camino Real between First Street and Newport Avenue from a four -lane Secondary Arterial to a two-lane collector roadway. The roadway segment of El Camino Real has a north -south alignment before it transitions to a northwest -southeast alignment between Sixth Street and Newport Avenue. This portion of El Camino Real is located within the City's Old Town commercial district, which supports a mixture of retail and commercial uses and includes various public improvements to provide a more pedestrian -oriented environment. In November 1997, the City, in coordination with the Orange County Transportation Authority (OCTA), approved a demonstration project to reduce the number of travel lanes on El Camino Real between Second Street to Sixth Street ( one block south of First Street and west of Newport Avenue) from a four -lane undivided Secondary Arterial street to a two-lane undivided collector street with diagonal parking along both sides of the street. The purpose of the demonstration project was to document the existing and define the future impacts of the redesignation on other nearby streets and intersections. A subsequent traffic study (Appendix B of this IS) was prepared by WPA/Willdan in May 2001 that concluded that 2020 traffic conditions, both with and without the project, would result in acceptable daily traffic levels and intersection operations. Following the success of the demonstration project and the preparation of the traffic study, the OCTA approved an amendment to the MPAH to change the status of the street segment of El Camino Real between First Street and Newport Avenue from a four lane secondary arterial to a two lane local collector roadway. The proposed General Plan Amendment would similarly reflect the existing and planned two-lane collector status of the roadway on the City's Circulation Element and ensure consistency between the City's General Plan and OCTA's MPAH. The proposed action is limited to the amendment to the Circulation Element of the General Plan. Since the physical changes to the roadway have already been implemented, the proposed project does not include changes to the existing physical environment. The changes that occurred in the past are included as part of the environmental setting defined as the physical conditions existing at the time environmental analysis is commenced (CEQA Guidelines Section 15125). The purpose of the proposed amendment to the City's Circulation Element is to (1) achieve consistency with the MPAH designation, (2) reflect the existing and future traffic levels on the roadway segment, and (3) ensure consistency between the roadway and the adjacent land uses by supporting the pedestrian -friendly character of the Old Town commercial district. The two-lane configuration and on -street diagonal parking are consistent with the revitalization goals for Old Town by contributing to a pedestrian -oriented environment.

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 in Section D below. ❑ Aesthetics ❑ Air Quality ❑ Cultural Resources ❑ Hazards & Hazardous Materials ❑ Land Use/Planning ❑ Noise ❑ Public Services ❑ Transportation/Traffic ❑ Mandatory Findings of Significance C. DETERMINATION: On the basis of this initial evaluation: ❑ Agriculture Resources ❑ Biological Resources ❑ Geology/Soils ❑ Hydrology/Water Quality ❑ Mineral Resources ❑ Population/Housing ❑ Recreation ❑ Utilities/Service Systems ® I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. ❑ I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. ❑ I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. ❑ I find that although 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 in the attached sheets. An. ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. ❑ I 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, and no further documentation is required. Preparer: ,SGoff Ree)(�5-,6r1 Elizabeth A. Binsack, Community Development Director PActu330\Final Sent\Section 3 Checklist.doc Title 66'oror P1,000er- Date Z.12/O5— D. EVALUATION OF ENVIRONMENTAL IMPACTS Directions 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 and 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 into account the whole action involved, including off-site, on-site, cumulative project level, indirect, direct, construction, and 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, and EIR is required. 4) "Negative Declaration: Less Than Significant With Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less than Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section XVII, "Earlier Analyses," may be cross- referenced). 5) Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA 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 which 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, 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 normally address the questions from this checklist that are relevant to a project's environmental effects in whatever format is selected. 9) The explanation of each issue should identify: a) the significance criteria or threshold, if any, used to evaluate each question; and, b) the mitigation measure identified, if any, to reduce the impact to less than significance.

No Impact. According to the County General Plan's Resources Element, no open space/scenic resources are located within or near the project study area. The Conservation/Open Space/Recreation Element of the City's General Plan states that the Peters Canyon ridgeline is a prominent visual feature in east Tustin that should be protected. The proposed General Plan Amendment will have no effect on this or any other visual/natural resource within the City or the County. b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a State Scenic Highway? No Impact. There are no natural scenic resources located within the project study area (El Camino Real between First Street and Newport Avenue [see Figure 2.1], nor is the project site located within a State Scenic Highway. Part of El Camino Real, however, is within a historic resource area of the City called the Cultural Resources Overlay District. It also passes through the Old Town commercial district. The proposed project is to reclassify a portion of El Camino Real from a four -lane Secondary Arterial to a two-lane collector in the Circulation Element of the City's General Plan. Reducing the designated number of lanes will not adversely impact scenic resources. On the contrary, the proposed General Plan amendment may benefit the historic resource by maintaining a two-lane, pedestrian - oriented roadway. c) Substantially degrade the existing visual character or quality of the site and its surroundings? No Impact. Please refer to discussion 4.1(a), above. d) Create a new source of substantial light or glare that would adversely affect day or nighttime views in the area? No Impact. The proposed project does not involve construction of any kind and does not involve any change to the existing street lighting. Therefore, the proposed project will not affect day or nighttime views in the area relating to light, glare, shadows, or shading. 4.2 Agricultural Resources In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Department of Conservation as an optional model to us in assessing impacts on agriculture and farmland.

The City of Tustin (City) General Plan and Farmland Mapping and Monitoring Program (State Department of Conservation, 2000) do not identify any designated farmland in the project study area. Therefore, the proposed project will not have an impact to designated farmland. b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? No Impact. There is no agriculturally zoned land, or land protected by a Williamson Act contract, within the study area. Therefore, there will be no impact to agriculturally zoned or protected lands. c) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland to nonagriculture? No Impact. The proposed project is a General Plan Amendment to reclassify a portion of El Camino Real that will result in maintaining the existing two-lane configuration of the roadway, consistent with the future two-lane build out condition identified in the MPAH. The proposed project will not result in changes in the existing environment and therefore will not lead to the conversion of existing farmland. 4.3 Air Quality Would the project: a) Conflict with or obstruct implementation of the applicable air quality plan? No Impact. California is divided into 15 air basins for the purpose of managing the air resources of the State on a regional basis. Areas within each air basin are considered to share the same air masses and are therefore expected to have similar ambient air quality. Additionally, the State is divided into 35 Air Pollution Control Districts (APCD) and Air Quality Management Districts (AQMD), which are county or regional authorities that have primary responsibility for controlling air pollution. Air basin boundaries may fall within the jurisdiction of one or more APCD/AQMD. The City is geographically located within the South Coast Air Basin (Basin). Air quality conditions in the Basin are under the jurisdiction of the South Coast Air Quality Management District (SCAQMD). The SCAQMD regulates stationary sources of pollution throughout its jurisdiction area. Direct emissions from motor vehicles are regulated by the California Air Resources Board (CARB). The SCAQMD governing Board approved the 2003 Air Quality Management Plan (AQMP) in August 2003 and submitted it to the California Air Resources Board and the U.S. Environmental Planning Agency for approval. The SCAQMD also establishes construction and operational emissions thresholds for the Basin. PActu330\Fina1 Sent\Section 4.doc «01/28/05» 4-2 LSA ASSOCIATES, INC. DRAFT INITIAL STUDY MARCH 2005 TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT The proposed project is a General Plan Amendment to reclassify El Camino Real between First Street and Newport Avenue. The General Plan Amendment designates the roadway a two-lane collector, consistent with existing conditions. Therefore, the proposed project will not result in a physical change to existing conditions. The proposed General Plan Amendment is consistent with the adopted MPAH. New development within the City shall comply with the density and intensity standards outlined in the Land Use Element and the City's current Zoning Ordinance. Implementation of the proposed amendment to the Circulation Element will be consistent with the Land Use Element of the City's General Plan. The City's Land Use Element, along with the plans of other cities and counties in the region, are reflected in the assumptions for the land use, traffic, population, and air quality projections used to develop the AQMP. Therefore, the proposed project will not conflict with or obstruct implementation of the AQMP. In addition, the proposed project is intended to ensure consistency between the affected portion of El Camino Real and the adjacent land uses by supporting the pedestrian -friendly character of the Old Town commercial district. The two-lane roadway configuration and on -street diagonal parking are consistent with the revitalization goals for Old Town by contributing to a pedestrian -oriented environment. The proposed project will support continued and increased pedestrian activity in this area of the City, and is therefore consistent with the goal of the AQMP to implement land use patterns that reduce overall vehicle trips and vehicle miles traveled. b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? No Impact. New development within the City is required to comply with the density and intensity standards outlined in the Land Use Element and the City's current Zoning Ordinance. Implementation of the proposed amendment to the Circulation Element will be consistent with the Land Use Element of the City's General Plan, which is reflected in the assumptions for the projections used to develop the AQMP. The AQMP identifies a number of air pollution reduction goals, measures, and policies. Local jurisdictions have been mandated to reduce a fair share proportion of vehicle pollution through the adoption of a menu of optional transportation control measures (TCMs) that have been identified by the local agency to be politically and economically feasible. In addition, the 2001 City General Plan, Conservation/Open Space/Recreation Element, includes air quality goals and policies intended to reduce emissions through proper land use and transportation planning, implementation of Transportation Demand Management (TDM) programs, alternative transportation modes, and reduced energy consumption. The proposed project is consistent with the Land Use and Conservation/Open Space/Recreation Elements of the City's General Plan and with the MPAH. It will not result in a change to the existing physical environment. It will result in the reclassification of the existing designation of this portion of El Camino Real to one that accommodates lower traffic volumes. Some traffic that would have used El Camino Real will be redistributed to adjacent, parallel streets; however, the overall traffic volumes P:\ctu330\Final Sent\Section 4.doc «01/28/05» 4-3 LSA ASSOCIATES, INC. DRAFT INITIAL STUDY MARCH 2005 TUSTINIEL CAMINO GENERAL PLAN AMENDMENT in the vicinity of the project will remain essentially the same. In other words, the increased traffic volume on adjacent streets would offset the lower traffic volumes on El Camino Real. Total vehicular emissions within the study area would remain similar before and after the proposed project. In addition, the County of Orange is in attainment with the State CO standard, and no monitoring stations in the County have recorded any CO exceedances in the past five years. Therefore, the proposed project is not expected to result in new, or contribute to existing, air quality violations. c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is nonattainment under an applicable federal or state ambient air quality standard (including releasing emissions, which exceed quantitative thresholds for ozone precursors)? No Impact. The proposed project is consistent with Land Use and Conservation/Open Space/Recreation Elements of the City's General Plan and with the MPAH. It will not result in a change to the existing physical environment. It will result in the downgrade of the existing designation of this portion of El Camino Real. Total vehicular emissions within the study area would remain similar before and after the proposed project. Therefore, the proposed project will not contribute to adverse, cumulative air quality conditions. d) Expose sensitive receptors to substantial pollutant concentrations? No Impact. The proposed project is a General Plan Amendment to the City's Circulation Element that will match existing conditions with proposed future conditions for the portion of El Camino Real between First Street and Newport Avenue. The project will not require construction activities; therefore, there will be no construction air quality impacts to nearby uses. There will be no physical change to the existing roadway configuration. Changes in the number of vehicular trips associated with the proposed project would affect the traffic at intersections and along roadway segments in the project vicinity. The primary mobile source pollutant of local concern is carbon monoxide (CO). CO concentration is a direct function of vehicle idling time and, thus, traffic flow conditions. CO disperses rapidly with distance from the source under normal meteorological conditions. Typically, high CO concentrations are associated with roadways or intersections operating at unacceptable levels of service or with extremely high traffic volumes. The Traffic Study (Appendix B) addressed 2020 traffic conditions in the study area under "with project" conditions (El Camino Real at two lanes between First Street and Newport Avenue) and "without project" conditions (El Camino Real at four lanes between First Street and Newport Avenue). The traffic study found that under both conditions, the daily traffic levels on the street segment and the study intersections would continue to maintain acceptable levels of service. Therefore, the project is not expected to result in a substantial increase in pollutant concentration as a result of traffic congestion. The County of Orange is in attainment with the State CO standard, and no monitoring stations in the County have recorded any CO exceedances in the past five years. The proposed project is not expected to result in any substantial changes in CO concentrations. Because no CO hotspots are anticipated, no sensitive receptors would be affected by project -related local air quality impacts. PAM330\Final Sent\Section 4.doc «01/28/05» 4-4 LSA ASSOCIATES, INC. MARCH 2005 DRAFT INITIAL STUDY TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT e) Create objectionable odors affecting a substantial number of people? No Impact. The proposed project will not require construction activity; therefore, there will be no odors from the application of asphalt or paint. The project will not result in a change to existing physical environment; therefore, no odors will be created. 4.4 Biological Resources Would the project: a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? No Impact. The project site is currently a two-lane road located in an urban area. There are no known animal species inhabiting the site. The City and County General Plans (2001, 2000) do not indicate any sensitive or special status species on the project site. b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations or by the California Department of Fish and Game or US Fish and Wildlife Service? No Impact. According to Figure COSR-2 in the City's General Plan, the site has not been identified as being the location of an important natural resource (i.e., a sensitive natural community). Peter's Canyon Regional Park is identified as a significant natural resource in the City, and the site of the proposed project is not located in or adjacent to the park. 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. The Lower Peters Canyon Retarding Basin contains a small amount of riparian habitat. However, the wetlands are not in close proximity to the proposed project site and would not be affected by the project. d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? PAU030\Final Sent\Section 4.doc 01/28/05» 4-5 T_._. - ---- LSA ASSOCIATES, INC. DRAFT INITIAL STUDY MARCH 2005 TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT No Impact. The project site is an existing roadway. It has not been identified as a crucial portion of the migratory path of any animal species. Its usefulness to migratory species would be limited, considering that it has no natural water sources or habitat. e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? No Impact. Two tree groups that are identified in the General Plan as important to the City are eucalyptus windrow and redwood grove. The proposed project would not result in the removal of, or otherwise adversely impact, these tree communities. No specific local policies or ordinances would be violated by the proposed project. 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? No Impact. The Natural Community Conservation Plan (NCCP), as prepared by the County of Orange Environmental Management Agency, covers a large portion of Orange County, including portions of the City of Tustin. The proposed project is located outside the NCCP and will not conflict with its policies. 4.5 Cultural Resources Would the project: a) Cause a substantial adverse change in the significance of a historical resource as defined in CEQA Guidelines Section 15064.5? No Impact. Cultural resources are places, structures, or objects that are important for scientific, historic, and/or religious reasons to cultures, communities, groups, or individuals. Cultural resources include historic and prehistoric archaeological sites, architectural remains, engineering structures, and artifacts that provide evidence of past human activity. They also include places, resources, or items of importance in the traditions of societies and religions. CEQA Guidelines Section 15064.5 defines historic resources as any object, building, structure, site, area, place, record, manuscript, or other resource listed or determined to be eligible for listing by the State Historical Resources Commission, a local register of historic resources, or the Lead Agency. Generally, a resources is considered to be "historically significant" if it meets one of the following criteria: • is associated with events that have made a significant contribution to the broad patterns of California's history and cultural heritage; • is associated with the lives of important persons in the past; • embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values; or PActuBOTinal Sent\Section 4.doc «01/28/05» 4-6 LSA ASSOCIATES, INC. DRAFT INITIAL STUDY MARCH 2005 TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT has yielded, or may be likely to yield, information important in prehistory or history. El Camino Real between First Street and Newport Avenue is within an area of the City known as Old Town. The Old Town District characterizes the City's historical and architectural focus. The area south of First Street, and on either side of Camino Real, is a City designated Cultural Resources District. The purpose of the district is to provide a framework for recognizing, preserving, and protecting culturally significant structures, natural features, sites, and neighborhoods within the City of Tustin. The proposed reclassification of this portion of El Camino Real is intended to allow for the continuation of the existing on -street diagonal parking and to support the pedestrian focus of the Old Town District. The pedestrian -friendly nature of the street is consistent with the historical and architectural context of the adjacent land uses, including Old Town and the adjacent Cultural Resources District. Therefore, there are no adverse effects associated with maintaining El Camino Real in current conditions on the historic character and historic resources in Old Town. b) Cause a substantial adverse change in the significance of an archaeological resource pursu- ant to CEQA Guidelines Section 15064.5? No Impact. The proposed project will not result in any construction activities, including grading, and therefore will not impact any archaeological resources. c) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? No Impact. The proposed project will not result in any construction activities, including grading, and therefore will not impact any paleontological resources. d) Disturb any human remains, including those interred outside of formal cemeteries? No Impact. The proposed project will not result in any construction activities, including grading, and therefore will not impact any interred human remains. 4.6 Geology and Soils Would the project: 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 PActuBOTinal Sent\Section 4.doc «01/28/05» 4-7 LSA ASSOCIATES, INC. MARCH 2005 DRAFT INITIAL STUDY TUSTINIEL CAMINO GENERAL PLAN AMENDMENT substantial evidences of known fault? Refer to Division of Mines and Geological Special Publication 42. No Impact. The Alquist-Priolo Special Studies Zones Act was signed into law in 1972. In 1994, it was renamed the Alquist-Priolo Earthquake Fault Zoning Act (A -P Act). The primary purpose of the Act is to mitigate the hazard of fault rupture by prohibiting the location of structures for human occupancy across the trace of an active fault. The A -P Act requires the State Geologist (Chief of the California Geology Survey) to delineate "Earthquake Fault Zones" along faults that are "sufficiently active" and "well-defined." The boundary of an "Earthquake Fault Zone" is generally about 500 feet from major active faults and 200 to 300 feet from well-defined minor faults. The A -P Act dictates that cities and counties withhold development permits for sites within an Alquist-Priolo Earthquake Fault Zone until geologic investigations demonstrate that the sites are not threatened by surface displacements from future faulting. There are no known active or suspected potentially active faults within the City of Tustin (City General Plan, Public Safety Element, 2001). (ii) Strong seismic ground shaking? No Impact. No faults have been mapped immediately near the City, although several major faults lie within 10 to 45 miles of the City. Therefore, the City would experience decreased magnitude or lesser ground shaking from an adjacent fault rupture. Development within the City will be designed and constructed in accordance with requirements of the latest edition of the Uniform Building Code standards and applicable City requirements. Adherence to these requirements will reduce potential impacts associated with new construction to a less than significant level. The proposed project does not result in new construction but rather a General Plan Amendment to maintain existing conditions. The segment of El Camino Real does not include any bridges or overpasses that would be subject to seismic evaluation and retrofit. The portion of Interstate 5 adjacent to El Camino Real was upgraded in the mid-1990s and is in compliance with seismic safety requirements. Therefore, the proposed project will not expose people or structures to substantial adverse effects associated with strong seismic ground shaking. (iii) Seismic -related ground failure, including liquefaction? No Impact. Liquefaction is a process by which water -saturated materials (including soil, sediment, and certain types of volcanic deposits) lose strength and may fail during strong ground shaking. Liquefaction is defined as "the transformation of a granular material from a solid state into a liquefied state as a consequence of increased pore -water pressure." The project study area is not located within an area subject to liquefaction as defined in the County of Orange General Plan Safety Element (Figure IX -12). Therefore, the proposed project is not expected to expose people or structures to potential substantial adverse effects associated with liquefaction. (iv) Landslides? No Impact. The study area's flat topography minimizes the potential for landslides, liquefaction, settlement, or other seismically related hazards. Furthermore, new development within the City will PActu330\Fina1 Sent\Section 4.doc «01/28/05» 4-8 LSA ASSOCIATES, INC. MARCH 2005 DRAFT INITIAL STUDY TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT be designed and constructed to meet the most current safety standards included in the Uniform Building Code and/or standards established by the City. The proposed project does not involve new construction and will not increase any risks associated with landslides. b) Result in substantial soil erosion or the loss of topsoil? No Impact. The proposed project will not require earthmoving activities, which would expose soils and thereby increase the potential for erosion or loss of topsoil. Therefore, the proposed project will not result in soil erosion or loss of topsoil. 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- or off-site landslides, lateral spreading, subsidence, liquefaction or collapse? No Impact. Refer to Responses 6a(iii) and 6a(iv). 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? No Impact. Expansive soils have a significant amount of clay particles that 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 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. Expansive soils are not identified in the County General Plan. The proposed project will result in the maintenance of the existing two-lane condition of this segment of El Camino Real. The proposed project does not involve any new construction and therefore will not create risks associated with expansive soil. e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? No Impact. The proposed project will result in the maintenance of the existing two-lane condition of this segment of El Camino Real and will have no effect on sewer availability. 4.7 Hazards and Hazardous Materials Would the project: a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? PAM330\1`inal Sent\Section 4.doc «01/28/05» 4-9 LSA ASSOCIATES, INC. MARCH 2005 DRAFT INITIAL STUDY TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT No Impact. The proposed project involves a General Plan Amendment to reclassify a portion of El Camino Real from a four -lane Secondary Arterial to a two-lane local collector roadway to be consistent with the MPAH. The proposed project will not involve the transport, use, or disposal of hazardous materials, nor demolition or construction activity. The City of Tustin is concerned with hazardous materials that are transported through the planning area either by aboveground transport or via underground pipeline. The City follows the Orange County Hazardous Waste Management Plan (1991), which contains policy direction and action programs to deal with incidences of hazardous waste emissions goals to prevent hazardous material emergencies include having transportation routes to safely transport any hazardous materials. The Marine Corps Air Station (MCAS), located on Barranca Parkway between Jamboree Road and Red Hill Avenue in Tustin, is identified as a source of hazardous materials. Identification and clean up of hazardous waste disposal sites on military bases occurs under the Comprehensive Environmental Response, Compensation Liability Act (CERCLA). The Department of the Navy would implement CERCLA policies for the MCAS. The MCAS is located over two miles from the project site and poses no threat to the site. 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? No Impact. Refer to Response 4.7(a), above. 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. According to Thomas Brothers Maps (2003), there are no existing school sites within one-quarter mile of the project site. Therefore, there are no impacts associated with this issue. Also, refer to Response 4.7(a), above. d) Be located on a 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 proposed project involves a General Plan Amendment to reclassify a portion of El Camino Real from a four -lane Secondary Arterial to a two-lane collector roadway to be consistent with the MPAH. The project does not involve grading, demolition, or construction; therefore, a search of known hazardous material sites in the vicinity of the project site is not warranted. 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? PActu330\Fina1 Sent\Section 4.doc a0l /28/05» 4-10 LSA ASSOCIATES, INC. DRAFT INITIAL STUDY MARCH 2005 TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT No Impact. The proposed project location is over four miles from John Wayne Airport and is not located within the John Wayne Airport land use plan. The landing flight path of aircraft, however, is near or over the project site location. Generally, if a site is greater than two miles away from an airport and it is not under a direct flight path, then the impact and safety threat from the airport is negligible. Safety hazards related to this issue are anticipated to be less than significant. 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. There are no private airstrips identified in close proximity to the proposed project location. The proposed project will not affect or be affected by private airstrips. g) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? Less Than Significant Impact. El Camino Real is an existing Evacuation Route, according to Figure PS -1 of the Public Safety Element of the City's General Plan. The City's Emergency Operations Plan identifies routes through the City that are suitable for use as evacuation routes. The Public Safety Element of the General Plan states that the extent and severity of a disaster will determine which routes and which directions people may take in order to escape the afflicted areas. El Camino Real is identified as an existing evacuation route that terminates at First Street and Jamboree Road. El Camino Real does not provide a direct connection to major freeways or to major arterials in other communities, and as such is the only evacuation route that is entirely contained within the City limits. While the reconfiguration of the affected portion of El Camino Real reduces its capacity, its current status as an evacuation route will not be adversely impacted. As the Public Safety Element of the General Plan states, the extent and severity of a disaster will determine which routes and which directions people may take in the event of an emergency; therefore, the reconfiguration of one of many existing evacuation routes will not impair implementation of or physically interfere with the adopted emergency response/evacuation plan. The proposed project does not involve demolition or new construction, nor will it induce population growth. The area immediately surrounding the project site is fully built out and is not anticipated to increase in occupancy. Therefore, it is not anticipated to increase a need for emergency response or the re-routing of evacuation plans. 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 residences are intermixed with wildlands? No Impact. The project site is located in an urban area with no wildlands in close proximity. The project does not involve the construction of any residential or commercial areas. Therefore, the project would not expose people or structures to a significant risk of loss, injury, or death from wildfires. PActu330\Fina1 Sent\.Section 4.doc e01/28/05» 4-11 LSA ASSOCIATES, INC. DRAFT INITIAL STUDY MARCH 2005 TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT 4.8 Hydrology and Water Quality Would the project: a) Violate any water quality standards or waste discharge requirements? No Impact. The proposed project is a General Plan Amendment that will allow the continuation of the existing roadway configuration. There will be no change to existing water quality or discharge requirements as a result of the project. 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 pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? No Impact. The proposed project is a General Plan Amendment to reclassify a portion of El Camino Real from a four -lane Secondary Arterial to a two-lane collector roadway to be consistent with the MPAH. The proposed project would not cause any long-term interference with groundwater recharge or affect existing aquifer volumes because the project does not involve construction. Therefore, there are no impacts associated with depletion of groundwater supplies. 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- or off-site? No Impact. The project site is an existing road located on relatively level topography. The site is not in close proximity to a stream or river, nor would runoff from it be expected to enter a stream or river and alter its course. The existing drainage pattern would remain unchanged as a result of the proposed General Plan Amendment. The proposed project would not alter existing drainage, and no significant impacts associated with erosion or siltation are anticipated. 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- or off-site? No Impact. The proposed General Plan Amendment would not alter existing drainage conditions nor would it cause flooding to the area. 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? No Impact. The proposed project is a General Plan Amendment to allow the maintenance of the existing roadway configuration. It will not create or contribute runoff water. Existing storm drain PActuBO Final Sent\Section 4.doc «01/28/05» 4-12 LSA ASSOCIATES, INC. DRAFT INITIAL STUDY MARCH 2005 TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT capacity will not be affected, nor will the project increase polluted runoff. The proposed project will not substantially increase sources of polluted runoff. f) Otherwise substantially degrade water quality? No Impact. The proposed project is a General Plan Amendment to reclassify a portion of El Camino Real from a four -lane Secondary Arterial to a two-lane collector roadway to be consistent with the MPAH. The proposed project will not change or degrade water quality. 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 hazard delineation map? No Impact. The proposed project does not include the addition of new housing. According to the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM), the project site is not located in a special flood hazard area (100 -year or less floodplain); therefore, there are no impacts associated with housing and flood hazards. Source: FIRM Map No. 06059CO030 E, September 15, 1989. h) Place within a 100 -year flood hazard area structures which would impede or redirect flood flows? No Impact. While the proposed project site is located in a 500 -year floodplain, it does not include the addition of new structures. Therefore, there are no impacts associated with structures redirecting flood flow. Source: FIRM Map No. 06059CO030 E, September 15, 1989. 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? No Impact. The project site is not located in the vicinity of a large body of water with a levee or a dam, nor does the project involve the construction of homes or any other structures. Therefore, there is no impact associated with damage from the failure of a levee or a dam associated with the proposed project. j) Inundation by seiche, tsunami, or mudflow? No Impact. A seiche is an oscillation of a landlocked body of water that can cause water damage to buildings, roads, and infrastructure that surround the body of water. There is no such body of water located in the City of Tustin. Therefore, impacts to the project study area associated with seiches will not occur. The project site is over 20 miles from the Pacific Ocean or any body of water that could cause tsunami, also know as a tidal wave, to the area. There is no risk of tsunami associated with the project. The project is located on relatively level topography, is not adjacent to hills or mountains that could be the source of mud flow or landslide, and is therefore not at risk for mud flow damage. PActu330\Final SenASection 4.doc 4 1 /28/05» 4-13 LSA ASSOCIATES, INC. DRAFT INITIAL STUDY MARCH 2005 TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT k) Potentially impact stormwater runoff from construction activities? No Impact. The proposed project is a General Plan Amendment to allow the maintenance of the existing roadway configuration. There are no new construction activities associated with this action. The proposed amendment will not result in a change to existing runoff conditions. 1) Potentially impact stormwater runoff from post -construction activities? No Impact. The proposed project is a General Plan Amendment that will allow the continuation of the existing roadway configuration. There will be no change to existing stormwater runoff as a result of the project. m) Result in a potential for discharge of stormwater pollutants from areas of material storage, vehicle or equipment fueling, vehicle or equipment maintenance (including washing), waste handling, hazardous materials handling or storage, delivery areas, loading docks or other outdoor work areas? The proposed project is a General Plan Amendment to reclassify a portion of El Camino Real from a four -lane Secondary Arterial to a two-lane collector roadway to be consistent with the MPAH. The project does not include areas of material storage, vehicle or equipment fueling, vehicle or equipment maintenance, waste handling, hazardous materials handling or storage, delivery areas, loading docks or other outdoor work areas. Therefore, the proposed project would not result in a potential for discharge of storm water pollutants as a result of these uses. n) Result in a potential for discharge of stormwater to affect the beneficial uses of the receiving waters? No Impact. The proposed project is a General Plan Amendment that will allow the continuation of the existing roadway configuration. There will be no change to existing stormwater runoff as a result of the project, and therefore no potential to affect the beneficial uses of the receiving waters. o) Create the potential for significant changes in the flow velocity or volume of stormwater runoff to cause environmental harm? No Impact. The proposed project is a General Plan Amendment that will allow the continuation of the existing roadway configuration. There will be no change to existing stormwater flow velocity or volume as a result of the project. p) Create significant increases in erosion of the project site or surrounding areas? No Impact. The proposed project is a General Plan Amendment that will allow the continuation of the existing roadway configuration. There will be no change to existing stormwater runoff as a result of the project; and therefore no increase in erosion potential for the project site or surrounding areas. P:\ctu330\Fina1 Sent\Section 4.doc a01/28/05» 4-14 LSA ASSOCIATES, INC. MARCH 2005 4.9 Land Use and Planning Would the project: a) Physically divide an established community? DRAFT INITIAL STUDY TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT No Impact. The proposed project would result in the maintenance of the existing roadway configuration as a two-lane undivided roadway with on -street diagonal parking. Previously, this roadway segment of El Camino Real was a four -lane undivided arterial street with parallel on -street parking. The reconfiguration and downgrading of the roadway was undertaken by the City and the OCTA in November 1997 as a demonstration project. The purpose of the proposed amendment to the City's Circulation Element is to (1) achieve consistency with the MPAH designation, (2) reflect the existing and future traffic levels on the roadway segment, and (3) ensure consistency between the roadway and the adjacent land uses by supporting the pedestrian -friendly character of the Old Town commercial district. The purpose of the demonstration project was to document the existing and define the future impacts of the redesignation of the roadway. The results of the Traffic Study (Appendix B) indicate that 2020 traffic conditions, both with and without the project, would maintain acceptable daily traffic levels and intersection operations. The proposed project is an amendment to the Circulation Element of the City's General Plan to institutionalize existing conditions and the MPAH designation of the roadway. The two-lane configuration and on-site diagonal parking are consistent with the revitalization goals for Old Town to create a pedestrian -oriented environment. The proposed project does not divide an established community; rather, it creates a stronger connection between the land uses on both sides of the street by creating better pedestrian access. 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. El Camino Real between First Street and Newport Avenue lies within an area that is designated as Old Town Commercial on the City's Land Use Policy map. The Old Town Commercial designation includes retail, professional office, and service-oriented business activities that serve Old Town and surrounding areas. The proposed project is consistent with, and furthers the intent of, several goals of the Land Use Element of the General Plan. Goal 3: Ensure that new development is compatible with surrounding land uses in the community, the City's circulation network, availability ofpublic facilities, existing development constraints, and the City's unique characteristics and resources. By downgrading the classification of El Camino Real within the Old Town district, the roadway classification will be compatible with the surrounding Old Town commercial uses, characterized by historic buildings and a pedestrian orientation. Nctu330\Final Sent\Section 4.doc «01/28/05» 4-15 LSA ASSOCIATES, INC. DRAFT INITIAL STUDY MARCH 2005 TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT Goal 5: Revitalize older commercial, industrial, and residential uses and properties. The proposed General Plan Amendment to maintain the existing configuration of El Camino Real in the Old Town district will support the revitalization efforts that rely on the historic character and pedestrian orientation of this unique commercial area. Goal 10: Improve and strengthen the Tustin Old Town/First Street area with a unique pedestrian environment and a diverse mix of goods, services, and uses. The Land Use Element of the General Plan (page 2 1 ) states, "The development character of Old Town and the First Street area can be significantly enhanced by greater integration of residential uses and physical renovations to existing buildings and street frontages which promote a pedestrian orientation." The proposed reclassification of El Camino Real from a Secondary Arterial to a collector in order to maintain the existing street configuration furthers the intent of this goal by maintaining a pedestrian -friendly environment. A collector street is characterized by slower speeds than the speeds of a Secondary Arterial. Additionally, the provision of on -street diagonal parking has a traffic calming effect and reduces travel speeds due to parking and backing -out maneuvers. The future street width will be two lanes instead of four lanes, which will allow for easier pedestrian street crossing. Finally, on -street parking provides convenient access to commercial establishments and reduces the need to provide additional public parking away from Old Town land uses. In addition to the general goals and policies in the Land Use Element, specific development guidance is provided for this area through the First Street Specific Plan and the Town Center Redevelopment project. The First Street Specific Plan encompasses approximately one mile along the First Street commercial corridor from central Tustin at Newport Avenue to the SR -55 freeway. The plan is intended to define the entry into Tustin from the west and to provide access to Old Town and the Civic Center. All development activities within this area of the City are subject to the provisions of the First Street Specific Plan. All development within the redevelopment project area is subject to design review and conformity with the redevelopment plan by the Redevelopment Agency. The proposed project is located within the Town Center Redevelopment Plan area. The Town Center Redevelopment Plan was approved in 1976 and has been amended several times since then. The objectives of the plan include creating a mixed-use town center, revitalizing the El Camino Real section of the redevelopment area, and increasing the level of capital improvements. The proposed redesignation of El Camino Real to a two-lane collector roadway is consistent with the redevelopment plan's intent of "... encouraging business development, attracting new customers to the area, alleviating pass-through traffic congestion and conflict, and improving safety." The portion of El Camino Real that intersects with First Street is located within the First Street Specific Plan (1985) area, which extends from Newport Avenue to the Newport Freeway. The Specific Plan provides the land use regulations and design guidelines to maintain and enhance the uses along First Street, create an attractive entrance to the City, rehabilitate facades and signage, improve vehicular circulation, and maximize pedestrian movement and access. As noted previously, the proposed General Plan Amendment to reclassify a portion of El Camino Real from a four -lane Secondary Arterial to a two-lane collector is consistent with the pedestrian -orientation of the area where it intersects with First Street and furthers the intent of the First Street Specific Plan.

DRAFT INITIAL STUDY MARCH 2005 TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT c) Conflict with any applicable habitat conservation plan or natural communities? No Impact. The City does not have a habitat conservation plan, and there are no natural communities in the study area. No impact would occur from the implementation on the proposed project. 4.10 Mineral Resources Would the project: 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. According to Figure VI -3 found in the County's General Plan Resources Element, no mineral resources are located in the project site. There are no impacts associated with mineral resources. 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. According to the County General Plan, there are no locally important mineral resource sites on the project site. There are no impacts associated with this issue. 4.11 Noise Would the project result in: a) Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? No Impact. The Noise Element of the General Plan identifies the noise contours for the build out conditions of the Land Use Policy Map. The General Plan noise contours were developed based upon existing and future traffic conditions, train operations, and other environmental conditions. The Noise Element defines the 60 dB CNEL contour as the noise impact area. Any proposed new noise sensitive land uses, such as residences, hospitals, schools, and churches, within the contour are to be evaluated on a project -specific basis. The 2010 Noise Map (Noise Element Figure N-1) identifies the study area for the El Camino Road redesignation as within the 60+ CNEL dB area. The Noise Element also notes that residences next to a number of major and secondary arterials in Tustin are exposed to a CNEL in excess of 65 dB, including El Camino Real. Noise levels below 65 dB are generally considered compatible with residential uses, and noise levels up to 70 dB are generally considered compatible with most commercial uses (Noise Element, Table N-2, Land Use Noise Compatibility Matrix). The proposed redesignation of this segment of El Camino Road will allow the maintenance of the existing roadway configuration. Some residences along the street frontage may currently experience noise in excess of 65 dB. However, noise levels on the road are not expected to change as a result of PActu330\Final Sent\Section 4.doc «01/28/05» 4-17 LSA ASSOCIATES, INC. MARCH 2005 DRAFT INITIAL STUDY TUSTINIEL CAMINO GENERAL PLAN AMENDMENT the project. Noise levels with the project may be less than what is accommodated for in the 2010 General Plan noise conditions if the 2010 noise modeling reflected the planned four -lane roadway configuration. The proposed project will not result in a substantive increase in noise levels compared with existing conditions; therefore, there will be no increase in noise exposure. b) Exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels? No Impact. The proposed project involves a General Plan Amendment to reclassify a portion of El Camino Real from a four -lane Secondary Arterial to a two-lane collector roadway. The downgrading of the roadway to match existing conditions will not result in an increase in groundborne vibration or noise levels. c) A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? Less Than Significant Impact. The proposed General Plan Amendment will allow the existing roadway configuration to continue in the future. Small increases in traffic may occur within the existing roadway as a result of growth and development in the surrounding areas; however, the proposed project will not cause land use growth beyond what is already planned for in the General Plan. Therefore, the project will not result in an increase in overall ambient noise levels. Some traffic that would have used El Camino Real when it was four lanes will now use parallel streets as a result of the reduction of travel lanes. The increased traffic on parallel streets will result in an increase in the traffic -related noise levels on those parallel streets. The Traffic Study (Appendix B) indicates that South B Street experiences a 5 to 10 percent increase in traffic as a result of the reconfiguration of El Camino Real. South C Street and Prospect Avenue experience a 1 percent increase in traffic. A 10 percent increase in traffic volumes would result in an increase of 0.4 dBA in traffic noise, which is not perceptible to the human ear. The incremental nature of the change in traffic levels is further documented in the Traffic Report, Figures 9 and 10, which illustrate an average daily traffic level of 5,800 in 2020 without the project and 5,900 in 2020 with implementation of the project (continuation of existing conditions). The increase of the daily traffic volumes from 5,800 to 5,900 would result in less than a 0.1 dBA increase in traffic noise, a negligible change. The incremental changes to traffic levels on streets that currently handle relatively low volumes of traffic is not sufficient to result in significant changes in traffic -related noise levels. d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? Less Than Significant Impact. See Response 4.11(c) above. 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? PActu330\Fina1 Sent\Section 4.doc «01/28/05» 4-18 LSA ASSOCIATES, INC. DRAFT INITIAL STUDY MARCH 2005 TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT No Impact. The project area is within two miles of the former Marine Corps Air Station Tustin (MCAS -Tustin); however, the former base was conveyed by the Department of the Navy to the City of Tustin, the Local Redevelopment Authority as designated by federal law. Nonaviation reuse plans are currently underway for the former base. The project is located over three miles from John Wayne Airport and is well outside the 60 dB and 65 dB aviation noise contour. The project is not within the airport land use plan or within two miles of the airport and will have no impact on aircraft noise exposure levels. f) For a 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 is not located within the vicinity of a private airstrip. 4.12 Population and Housing Would the project: a) Induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? No Impact. The proposed project involves a General Plan Amendment to reclassify a portion of El Camino Real from a four -lane Secondary Arterial to a two-lane collector roadway. The downgrading of the roadway to match existing conditions will not result in an increase in roadway capacity or traffic levels that could have growth -inducing effects. Future growth and development of the City is defined in the General Plan, including the Land Use and Growth Management Elements. The proposed project is consistent with these Elements and will not result in a change to the future population growth of the City. b) Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? No Impact. The proposed project will allow the maintenance of the existing two-lane configuration of this portion of El Camino Real with on -street diagonal parking. The project does not involve any new construction; therefore, no housing units will be displaced. c) Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? No Impact. Please refer to the response 12(b). Rktu330\Final Sent\Section 4.doc A1/28/05» 4-19 LSA ASSOCIATES, INC. DRAFT INITIAL STUDY MARCH 2005 TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT 4.13 Public Services a) 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 Fire Protection, Police Protection, Schools, or Parks? No Impact. The proposed project is to reclassify a portion of El Camino Real from a four -lane Secondary Arterial to a two-lane collector in the Circulation Element of the City's General Plan. The proposed project will not add new structures to the area or induce population growth. Therefore, governmental facilities will not be affected by the proposed project. 4.14 Recreation a) Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated No Impact. The proposed project will not increase population and housing in the area, and the demand for recreational facilities will not increase. Therefore, existing recreational facilities in the area will not be impacted by the proposed project. b) Does the project include recreational facilities or require the construction or expansion of recreational facilities that might have an adverse physical effect on the environment? No Impact. The project site is not located in or adjacent to a City or County recreational facility and will not require the construction or expansion of recreational facilities. Therefore, implementation of the project will not have a physical environmental impact relating to recreational facilities. 4.15 Transportation/Traffic Would the project: a) Cause an increase in traffic which is substantial in relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at intersections)? Less Than Significant Impact. The proposed General Plan Amendment to reclassify a portion of El Camino Real will not cause an increase in traffic. The Traffic Study (Appendix B) addressed 2020 conditions with El Camino Real as a two-lane roadway ("with project" conditions) and as a four -lane roadway ("without project" conditions). The study considered other changes to land use and traffic conditions that would occur over this period, including the redevelopment of Marine Corps Air Station (MCAS) Tustin base and the extension of Newport Avenue to the south. The traffic study assumed MCAS traffic model projections where possible (two locations) and a traffic growth rate of 1.0 percent per year to existing volumes at four study intersections. The growth rate was considered PAM330\1`inal Sent\Section 4.doc «01/28/05» 4-20 LSA ASSOCIATES, INC. DRAFT INITIAL STUDY MARCH 2005 TUSTIN/EL CAMINO GENERAL PLAN AMENDMENT conservative to represent a "worst-case" projection. A midblock arterial volume -to -capacity (v/c) analysis provided a general overview of roadway operation under both "with" and "without project" conditions. Intersection capacity utilization (ICU) analyses were conducted based on a.m. and p.m. peak -hour intersection turn volumes and the intersection approach lanes. Six study intersections were analyzed in order to address the potential impact of maintaining El Camino Real at two lanes on other streets and intersections. The selected study intersections were: • El Camino Real/First Street • El Camino Real/Main Street • El Camino Real/Newport Avenue • Main Street/Newport Avenue • Main Street/Prospect Avenue • Prospect Avenue/First Street See Figure 4.1 for information regarding existing traffic volumes and the location of study intersections. Figure 4.2 illustrates 2020 peak -hour traffic volumes with the project (two lanes), and Table 4.A summarizes the intersection analysis. The traffic study concluded the following: • All of the study intersections currently operate at acceptable levels of service (LOS) during the a.m. and p.m. peak hours. • Year 2020 traffic conditions "without project" were evaluated and showed that acceptable LOS values for the daily traffic analyses and the six study intersections are maintained. • Under "with project" conditions where the MPAH Amendment (two lanes on El Camino Real) is assumed to be in place, the street segment (daily traffic analyses) and study intersections continue to operate at an acceptable LOS. No significant traffic impacts are anticipated as a result of the El Camino Real redesignation. • No significant traffic -related impacts are expected for any jurisdictions outside of the City. b) Exceed, either individually or cumulatively, a level of service standard established by the City congestion management agency for designated roads or highways? No Impact. The OCTA is the congestion management agency for Orange County. The Orange County Congestion Management Plan (CMP) generally consists of a composite of submittals from local agencies, in which each local jurisdiction develops the required data in accordance with the guidelines established by the OCTA. The OCTA compiles the data and submits the results to the Southern California Association of Governments (SCAG) for a finding of regional consistency. Based on the success of the demonstration project and the results of the traffic study, the OCTA approved an amendment to the MPAH to reclassify El Camino Real between First Street and Newport Avenue to a two-lane collector road. The proposed project is a General Plan Amendment to the City's Circulation Element to create consistency with the adopted, countywide MPAH. Therefore, the proposed project is consistent with the standard established by the congestion management agencies.

No Impact. The proposed project will result in the maintenance of the existing roadway configuration of El Camino Real between First Street and Newport Avenue. Maintaining the existing roadway configuration will have no impact on air traffic patterns. d) Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? No Impact. The proposed project will result in the maintenance of the existing roadway configuration of El Camino Real between First Street and Newport Avenue. There will be no change to the existing roadway geometrics or to the existing intersections. Therefore, there will be no increase in traffic hazards. e) Result in inadequate emergency access? Less Than Significant Impact. El Camino Real is identified as an existing Evacuation Route according to Figures PS -1 of the Public Safety Element of the City's General Plan. The proposed project will result in the maintenance of the existing roadway configuration between First Street and Newport Avenue. Current emergency access and evacuation conditions would not change as a result of the project. Please see also response to 4.7 (g). f) Result in inadequate parking capacity? No Impact. Additional parking has been created as a result of changing El Camino Real from a four - lane roadway to a two-lane roadway with on -street diagonal parking. The proposed General Plan Amendment will result in the maintenance of the existing roadway configuration and therefore has a beneficial effect on parking in the Old Town commercial district. g) Conflict with adopted policies, plans, or programs supporting alternative transportation (e.g., bus turnouts, bicycle racks)? No Impact. The City provides access to several forms of alternative transportation such as buses, walking trails, and bike paths. The Circulation Element of the City's General Plan identifies existing public bus routes and existing and proposed bikeways. El Camino Real between First Street and Newport Avenue is currently served by a bus route; however, it is neither an existing or proposed bikeway. The existing two-lane configuration with on -street diagonal parking is a more pedestrian friendly environment than the four traffic lanes that existed prior to the demonstration project. The proposed project will maintain the existing pedestrian -oriented conditions and will not preclude continued bus service to the study area.

No Impact. The proposed project is a General Plan Amendment that will allow the continuation of the existing roadway configuration. There will be no change to existing storm water runoff treatment as a result of the project, and therefore no implementation of new or retrofitted storm water treatment control measures. 4.17 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? No Impact. The proposed project will result in the maintenance of the existing roadway configuration for the segment of El Camino Real between First Street and Newport Avenue. Sensitive species and cultural resources are not present within the existing right-of-way of the roadway. b) Does the project have impacts that are individually limited, but cumulatively considerable? Cumulatively considerable 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 pro- jects, and the effects of probable future projects)? No Impact. The proposed General Plan Amendment will allow the existing configuration of the street to remain, without adversely affecting nearby streets or intersections. The project will not make any substantial adverse contributions to cumulative impacts. The project may result in beneficial effects on land uses adjacent to the roadway and has been demonstrated to enhance revitalization of the Old Town area by supporting pedestrian orientation of the commercial district. c) Does the project have environmental effects, which will cause substantial adverse effects on human beings, either directly or indirectly? No Impact. The proposed downgrading of this segment of El Camino Real will further the goals of the Land Use Element of the General Plan and support the continued revitalization of the Old Town district. There are no substantial direct or indirect adverse effects. P:\ctuBffinal Sent\Section 4.doc «01/28/05» 4-27 LSA ASSOCIATES, INC. MARCH 2005 DRAFT INITIAL STUDY TUSTINIEL CAMINO GENERAL PLAN AMENDMENT APPENDIX A GENERAL PLAN AMENDMENT PACTUBMENrAppendix.doc a03/15/2005» Secondary: A four -lane undivided roadway, with a typical right-of-way width of 80 feet and a curb -to -curb pavement width of 64 feet. These roadways serve as collectors, distributing traffic between local streets, and major and primary arterials. For the MCAS Tustin Specific Plan, 80 -foot right-of-way was modified to a 92 -foot right-of-way to provide a painted median for two-way left turn lanes and Class H bicycle lanes. Collector: A two-lane undivided roadway, with a minimum right-of-way width of 66 feet and a minimum curb -to -curb width of 50 feet. The width maybe increased to accommodate roadway features such as bicycle lanes, on - street parking and turn lanes. At LOS "C," this road type accommodates up to approximately 10,000 vehicle trips per day. This road functions as a collector facility, however it tends to move traffic between two arterials rather than between local streets it has been added to the City's arterial highway system because it provides network continuity and is regionally significant, and may serve through traffic demand where projected volumes do not warrant a higher classification such as Secondary. The Circulation Element roadway classification system does not include private streets. Private street widths and cross-sections will vary from those described for roadways in this Element. Standard cross-sections represent the obvious and accepted answer to most situations. However, the standard cross-sections do not always provide the best solution to any given need or set of objectives. Reasonable flexibility and variety is provided for in the City's private street standards. Figure C-1 shows schematic cross sections of each category of arterial roadway. These sections represent desirable standards, but variation in right- of-way width and specific road improvements will occur in certain cases due to physical constraints and/or right-of-way limitations. In particular, the median width in eight -lane, six -lane and four -lane roadways will vary according to the area being served and the available right-of-way constraints and turn lane requirements. Hence, any of the arterial classifications may deviate from the standards where physical constraints exist or where preservation of community character dictates special treatment. Bikeway facilities are another factor which affect the specific standards applied for various facilities. The desirable goal for every classified street section is that it carry the designed volume of traffic at the desired level of service. Within this requirement, descriptions of width and facilities are offered as basic guidelines and as noted above, variation in design is expected, depending on CITY OF TUSTIN CIRCULATION ELEMENT GENERAL PLAN 20 April 18, 2005 8 -LANE MAJOR ARTERIAL 144' R/W 6 -LANE MAJOR ARTERIAL 120' R/W PRIMARY ARTERIAL 100' R/W 46' _ 98' SECONDARY ARTERIAL 92' R/W� (WITH CLASS 1I BICYCLE LANES) 4p40� 4' 32' SECONDARY ARTERIAL 80' R/W SOURCE: Austin -Foust Associates, Inc.

GENERAL PLAN CIRCULATION SYSTEM The goals and policies included in this Element emphasize the need for a circulation system that is capable of serving both existing and future residents while preserving community values and character. The location, design, and constituent modes of the circulation system have major impacts on air quality, noise, community appearance, and other elements of the environment.

These analyses are based upon field studies conducted by our staff, information provided by the City of Tustin, long range traffic model data,. previously completed studies and standard reference materials. The primary purpose of this evaluation is to identifyan otential traffic impacts that may result from the y p p y project and recommend mitigation measures as may be necessary. It is important to determine if acceptable traffic operations can be maintained for both current and future conditions, if the proposed project is implemented. I PROJECT DESCRIPTION This report analyzes the effects of amending a street segment of EI Camino Real between First Street and Newport Avenue from a four lane "Secondary" arterial to a two lane "Local" collector roadway. This roadway segment of El Camino Real has a north -south alignment before it transitions to a northwest -southeasterly alignment between Sixth Street and Newport Avenue. I_ The overall study street segment. of EI Camino Real is also located within the: City of Tustin's Old Town Commercial District, which supports a mixture of retail and commercial uses including �_. various public improvements to provide a more pedestrian oriented environment. Figure 7 illustrates the location of the proposed project in relationship to the surrounding street system. In November 1997, the City of Tustin, in coordination with the Orange County Transportation Authority (OCTA), approved a demonstration project to reduce the number of travel. lanes. on EI Camino Real between Second Street to Sixth Street from a four lane undivided Secondary arterial street to a two lane undivided Local collector street with diagonal parking along both sides of the street (Figure 2 provides a representation of the EI Camino Real study section). With more than three years of experience since its implementation, the existing and future impacts of the proposed Amendment are better defined. The potential operations of El Camino Real and the surrounding roadway network, resulting from the proposed Amendment and change in the roadway capacity (on EI Camino Real) is documented and. summarized in the following sections of this report.

This roadway has been operating under geometry, consistent with the proposed MPAH Amendment conditions, for several years. This allows stronger documentation of the potential impacts of the project, since the future operations presently exist and the analyses are based on conditions measured in the field (through counts), which are representative of the proposed MPAH Amendment conditions. The existing MPAH is illustrated in Figure 3, which reflects a four -lane roadway for the study section. This also provides an overview of the study section and its relationship to other Master Plan roadways. The number of lanes and conditions indicated in Figure 3 are not necessarily representative of existing field conditions, but show the current long-range plan. The current _.L status of some pertinent study area roads and their operations, are further addressed below. It is also important to note that EI Camino Real is central to the Old Town commercial. district as illustrated in Figure 4. A revitalization plan for the Old Town area was developed by the City of - Tustin in approximately 1991 and many elements can presently be seen in the area. There are on-going efforts to continue implementation of the plans and a significant element is the proposed MPAH Amendment for EI Camino Real. There was a significant amount of focus on this roadway and the development, which, is and would be adjacent to EI Camino Real. L El Camino Real presently has two undivided lanes from Sixth Street to Second Street and has a general north -south alignment. Four travel lanes are provided north and south of this section. On -street diagonal parking is available on both sides of EI Camino Real through the two-lane section, with some restrictions. EI Camino Real south of Sixth Street curves into a northwest— southeast orthwestsoutheast alignment and is a four lane undivided roadway with no on -street parking. A speed limit of 25 miles per hour (MPH) is posted. The proposed project would result in maintenance of this roadway configuration as a two-lane undivided roadway with on -street diagonal parking. Previously, this roadway segment on EI Camino Real was a four -lane undivided arterial street with parallel on -street parking. - Newport Avenue is a four -lane divided roadway in the study area and has a general northeast - southwest direction. A raised median divides the four travel lanes with 35 miles per hour (MPH) WPA Traffic Engineering El Camino Real MPRH Amendment (A Division of Willdan) 4 City of Tustin Job # 12680 �I 11 11 11 1 _1 .n 6M MAJOR (6 LANES) 4P PRIMARY (4 LANES, DIVIDED) 4S SECONDARY (4 LANES, UNDIVIDED) 2C LOCAL COLLECTOR (2 LANES) EI Camino Real MPAH Amendment JOB# 12680 WPA l�'�I ENGINEERINGC A DIVISION OF WILLDAN FIGURE 3 Existing MHAH Roadway Network W •L r 1 Y' '� . 1 ��`e1ti �y� y • �yv v1Q, * Le'.

The southern terminus of Newport Road is presently south of Sycamore Avenue, just north of the railroad tracks. Main Street is a two-lane undivided roadway in the immediate study area and has an east -west direction. The posted speed limit is 35 miles per hour (MPH). On -street parking is allowed with some restrictions. To the west, Main Street becomes Chestnut Avenue in the City of Santa Ana and terminates at Grand Avenue. In an easterly direction, there are four travel lanes east of Preble and Main Street transitions to become Bryan Avenue. First Street is a four -lane divided roadway in the study area and has a general east -west direction. A two-way left turn lane divides the four travel lanes in the study area and the posted speed limit is 30 miles per hour (MPH). On -street parking is allowed with some restrictions. To -- the west, First Street continues through the City of Santa Ana and eventually becomes Bolsa Avenue. To the east, First Street terminates in Tustin at Red Hill Avenue. Prospect Avenue is a two-lane undivided roadway between Main Street (the southerly terminus) and First Street with a north -south alignment. A speed limit of 25 miles per hour (MPH) is posted.

Prior to evaluation of the existing conditions, it is necessary to determine the scope of work for the proposed project. In compliance with OCTA procedures and policies regarding requests for MPAH Amendments, the City of Tustin developed a scope of work with OCTA as part of the Cooperative Study Agreement. Pursuant to the agreed upon scope between the OCTA and City Staff, six study intersections were analyzed in order to address the potential impact of the project. The study intersections are: WPA Traffic Engineering El Camino Reai MPRH Amendment - (A Division of Wilidan) 7 City of Tustin Job # 12680 I ♦ EI Camino Real / First Street ♦ EI Camino Real / Main Street -- ♦ EI Camino Real / Newport Avenue ♦ Main Street / Newport Avenue 1 ♦ Main Street / Prospect Avenue ♦ Prospect Avenue / First Street. -- Existing field data were collected for use in the analyses, which included the information shown in Figure 5. These existing approach lanes (Figure 5) at the study intersections are critical to the intersection analyses and in addition, factors such as driveway locations, type of adjacent development, general circulation patterns and other related information were noted but not illustrated. The existing conditions analyses also required collection of existing daily traffic volumes and AM/PM peak hour counts at the six study intersections, which can be referenced in Figures 6 and 7, respectively. The daily traffic count information serves to provide more general evaluations of roadway operations to supplement the more detailed existing (and future) z intersection analyses. Daily Traffic Analyses A The daily volume traffic analyses provide a general assessment of the current roadway conditions and can serve as a "baseline" for evaluation of the project related impacts. These _L analyses were based on current daily traffic volumes, compared to the existing roadway capacities established by the County of Orange, as well as previously included in the Orange County Congestion Management Program (CMP) document. The CMP previously required mid - block analyses as a part of the City's annual reporting procedures. The existing daily volumes used are based on the most recent counts conducted by the City of Tustin. Table 1 includes the County daily traffic "Capacities", applicable to the varying types of existing roadway segments found in the study area. The daily capacities shown in Table 1 are representative of maximum roadway operations (Level of Service "E") and serves as a base for volume to capacity reviews. The street segment roadway operations are typically evaluated through comparison of existing daily traffic volumes, divided by the theoretical (LOS E) capacities in order to provide a volume to capacity (WC) ratio. This V/C ratio then provides a measure for evaluating the roadway performance. Ranges of V/C ratios relate to varying Levels of Service (LOS), which is further explained below.

Traffic LOS values are qualitative descriptions of roadway operations and designated in terms of letters "A" through "F," with LOS °A" representing free flow conditions and LOS °F representing severe traffic congestion. The portion of the overall capacity used by the existing (and future) traffic determines the LOS assigned to a particular roadway. The City of Tustin requirements are consistent with generally recognized standards of acceptable roadway operations (LOS D, which relates to about 90 percent of the capacity). The qualitative, technical roadway operation description for each of the LOS "letters" is contained in Appendix A. The results of the daily traffic analyses are shown in Table 1. The V/C ratios for the study area street system, based on the existing volumes and existing road geometry, show acceptable LOS results. This is of particular relevance to the proposed MPAH Amendment, since the reduction of roadway capacity on EI Camino Real from a four -lane. Secondary arterial to a two- lane Local collector roadway has been in existence for several years and the effects are reflected in Table 1. In other words, the present roadway capacities (which include the two - lanes on EI Camino Real) provide acceptable levels of service for the area streets. Table 1 shows that EI Camino Real and the surrounding roadways are all operating at LOS D or better. It should be recognized that the street segment (mid -block) analyses are more general indicators of traffic operations due to the various inherent assumptions included in these evaluations. The intersection analyses provide a more detailed verification of traffic conditions. A summary of the analyses for the study intersections, agreed to be the focus of the evaluation within this cooperative study between the OCTA and the City of Tustin, is presented below. Intersection Analyses The recent AM and PM peak hour intersection counts conducted by the City of Tustin, at the six study intersections, served as bases for documenting existing conditions. These existing traffic volumes were combined with the current intersection geometric information, then incorporated into the Intersection Capacity Utilization (ICU) methodology of intersection analysis. The ICU methodology is the required procedure for Orange County CMP evaluations and widely utilized in the Southern California area. WPA Traffic Engineering El Camino Real MPRH Amendment (A Division of Wilidan) 13 City of Tustin Job # 12680 In this methodology, the critical intersection volumes are divided by the available lane capacities and other "lost" time is considered, resulting in an ICU value for the study location. The ICU value is then related to a Level of Service (LOS), which ranges from "A" (the best) to "F' (the worst). This procedure is very similar to the daily traffic "V/C" evaluation, although the ICU contains more analysis factors since the evaluation of intersection operations is inherently more complex than the street segments. It is the City policy that LOS results A through D represent acceptable operations, while LOS E and F are considered over capacity. The ICU analyses for the existing conditions are utilized to determine if any significant traffic impacts presently exist at the study area intersections. These ICU evaluations reflect present operations through the recent counts and current intersection approach lanes. It should be remembered the existing analyses actually provide a base condition that reflects the proposed MPAH Amendment, given the existence of the approved ECR demonstration project (two lanes exist for the majority of the study, section of ECR). Table 1 summarizes the results of, the ICU analyses at the six study intersections under existing ' conditions. As shown in Table 1, all the study intersections are operating at LOS C or better which documents acceptable existing operations (LOS D or better) during both the AM and PM 1 peak hours. Based upon the findings for existing conditions, with EI Camino Real currently operating as a two lane Local collector, there are no present adverse impacts or deficiencies in peak hour performance at all study intersections. The supporting intersection analysis worksheets are contained in Appendix B of this study. The existing count data, which were utilized in the analyses, can be referenced in Appendix C. FUTURE CONDITIONS WITHOUT PROJECT (Current MPRH — Four Lanes on ECR) The evaluations of future conditions under the current MPRH referenced previous year 2020 traffic modeling efforts performed for the City of Tustin and also include separate analyses of the intersections more "internal" to the project area. Extensive traffic modeling efforts were undertaken as a part of the Marine Corps Air Station (MCAS) Tustin Disposal and Reuse Traffic Study'. The year 2020 traffic modeling assumptions for the MCAS project included the current MPAH road system for the study area (i.e., ECR at four lanes) and specifically analyzed two of the study intersections agreed to be evaluated as a part of this MPAH Amendment project. WPA Traffic Engineering El Camino Real MPRH Amendment (A Division of Willdan) 14 City of Tustin Job # 12680 Traffic Prosection Methodology Two study intersections (Newport/ECR and Newport/Main) previously modeled and analyzed in the MCAS report were referenced directly for the "Without (MPAH) Project." condition. It was determined the other four study intersections, however, required detailed evaluations and considerations in order to reflect future conditions "Without the Project". These four intersections are more "internal" to the City. of Tustin and their future traffic increases are not expected to be as significantly influenced by traffic generated outside the City of Tustin. The projection of future traffic for the four "internal" intersections were determined to be best reflected through use of a reasonably conservative growth factor. Given the configuration of the street system and the relatively built out condition of the surrounding areas, it is anticipated the present traffic movements would provide the best representation of future traffic patterns. The traffic growth documented in the MCAS analyses, at the Newport Avenue study intersections, is shown to be in the 1.2 to 2.9 percent per year range. The Newport Avenue intersections, however, are anticipated to be subject to significantly greater through traffic increases, especially when factors such as the extension/connection of Newport Avenue to the south is _l considered. In order to provide an accurate evaluation of pre -project conditions, appropriate growth rates over a twenty-year growth period were utilized in this study. A traffic growth rate of 1.0 percent per year was applied to the existing volumes at the study intersections of EI Camino ReaV1 t Street and EI Camino Real/Main Street in these traffic analyses. A traffic growth rate of 1.0 percent per year was also applied to the existing volumes at the study intersections of Prospect Avenue/1$' Street and Prospect Avenue/Main Street in these analyses. These growth rates are intended to address the potential traffic increases due to various potential projects and/or general traffic growth in the study area. This provides a conservative growth rate and is anticipated to be representative of "worst case' projections. For purposes of evaluating the four "internal" study intersections, it is anticipated that application of the one percent per year growth factor through the year 2020 will provide a conservative projection of the future traffic volumes at these study locations. The growth factor, however, is ' "Marine Corps Air'Station (MCAS) Tustin Disposal and Reuse Traffic Study" Appendix B WPA Traffic Engineering El Camino Real MPAH Amendment (A Division of Wilidan) 15 City of Tustin Job # 12680 i - not the only consideration required. It must be recognized the existing intersection counts -. included the condition where EI Camino Real has two undivided lanes for most of the study sections. Adjustments were, therefore, required to assure the volumes used in these 'Without Project" analyses reflect four travel lanes on ECR. (It can be noted the Newport Avenue intersections do not require adjustment for these conditions since the MCAS modeling _ incorporated a four -lane condition for ECR). Trip origin and destination patterns for traffic using ECR as a through route were developed based upon the street system configuration, review of ECR. related traffic volumes, consideration of the types of area land uses, potential regional attractors, the current roadway configurations, and the changes planned for the project street classification. Numerous individual travel routes were. examined and evaluated. An overview of. the trip assignment patterns included in the origin/destination evaluations is illustrated in Figure 8. The numerous travel routes considered specifically examined the traffic that would be "drawn" to ECR if four lanes were to be provided. These "Without Project" analyses for the four "internal" `- intersections must consider the "draw" to ECR, since the existing counts reflect ECR at. its present two-lane configuration (and the growth factor is applied to these volumes). It should be recalled, the two -modeled intersections already included the assumption of four lanes on ECR, and so the Figure 8 "adjustments" are not applicable to the Newport Avenue intersections for the "Without Project' conditions. These same principals and considerations were also applied to the daily traffic volumes. The resulting daily and peak hour traffic volumes are illustrated in Figures 9 and 10, respectively. These volumes were then incorporated in the same analyses that were performed for the existing conditions. These evaluations will show how the future conditions compare to. the existing operations and also will serve to provide a baseline to .measure the "With" project operations against.

It can be seen the study locations maintain acceptable (LOS D or better) operations for conditions where four lanes are provided on EI Camino Real. It can also be noted, these daily traffic analyses were performed based on both the existing road configurations and the future MPAH lanes. Acceptable operations are noted under both geometric conditions. For EI Camino Real, only the four -lane condition is shown to clarify this is the "Without Project" scenario. Intersection Analyses The ICU worksheets document the traffic volumes, approach lanes and analyses of the "Without Project" traffic conditions, while the approach lanes and volumes used in these analyses are also shown in Figures 5 and 9, respectively. The existing intersection approach lanes are maintained to reflect a `worst case" and the volumes provide well-documented evaluation of the two Newport Avenue intersections and conservative analyses of the four "internal" intersections. The ICU worksheets can be referenced in .Appendix B. As shown in Table 2, acceptable LOS results are maintained at all of the study intersections for year 2020 "Without Project" conditions. FUTURE CONDITIONS WITH PROJECT (Proposed MPRH Amendment — 2 Lanes on ECR) The proposed MPAH Amendment is considered in this section through evaluation of the daily traffic conditions and detailed evaluation of the six study intersections. As was described earlier in this study, there is a high level of confidence in the results of these "With Project" analyses, which include the two lane configurations on EI Camino Real. In part, this is due to counts that could be taken while this configuration is actually "in place", as well as consideration of other pertinent traffic related factors (i.e., the layout of the surrounding street system, the relative built out condition of the surrounding areas, etc.). Figures 11 and 12 present the daily and AWPM peak hour volumes, which resulted from the same type of analyses and considerations applied in the "Without Project.' analyses. This serves to assure that the comparison of "With" to "Without" the Project is valid. These volumes were then incorporated in the same analyses that were performed for the previously considered conditions.

Of course, for EI Camino Real the "Project" is to provide a two-lane configuration, so only this condition is analyzed for the study segments. Table 1, which was presented earlier in this study, shows the proposed two-lane configuration for EI Camino Real would provide acceptable Levels of Service. This is shown to be the case for all of the study locations under both the existing roadway and future MPAH conditions. Intersection Analyses The estimated traffic growth was applied to the existing traffic volumes so the study intersections could be analyzed for the 'With Project" conditions. The proper adjustments to the study intersections were applied, depending on their locations, as was described in the "Without Project" conditions. The volumes in Figure 12 were then used in the ICU analyses, which were calculated for these 'With Project" (two lanes on EI Camino Real) analyses.- The existing intersection approach lanes (Figure S) were also utilized to consider the "worst case". The results for these "With Project' conditions can be referenced in Table 1. The mid -block arterial volume -to -capacity (V/C) analysis provides a more general overview of roadway operations, while these Intersection Capacity Utilization (ICU) analyses results in detailed evaluations of the intersections, which are the critical locations of the street system. The combination of the mid -block analysis component (utilizing the daily traffic volumes and. capacities) and the ICU analyses (based on AM and PM peak hour intersection turn volumes and the intersection approach lanes) serve to provide well documented evaluations of the anticipated operations and whether the proposed MPAH Amendment is feasible and can result in acceptable operations for the street system. For the proposed MPAH Amendment, no deficiencies are forecast, based on daily traffic V/C ratios or the detailed intersection analyses. IMPACTS TO OTHER JURISDICTIONS Given the location of the proposed MPAH Amendment of EI Camino Real, there is not expected to be very significant traffic impacts on any other jurisdiction. The changes in travel due to the proposed Amendment are shown to be "local" to the City of Tustin. In addition, since the proposed. project configuration presently exists, there are well defined indications of the future operations. WPA Traffic Engineering El Camino Real MPRH Amendment (A Division of Wilidan) 24 City of Tustin Job # 12680 L� SUMMARY This study has examined traffic factors related to the reclassification (MPAH Amendment) of EI Camino Real between First Street and Newport Avenue in the City of Tustin. The project is to change this section of EI Camino Real from a future four -lane Secondary arterial to a proposed two-lane Local roadway. It is noted, however, the present configuration of EI Camino Real between Sixth Street and Second Street is as a two-lane roadway. L This study addresses the potential project traffic impacts at the six designated study intersections, identified through agreement between OCTA and the City of Tustin. Existing traffic conditions were reviewed and quantified to provide a basis for this study. Potential year 2020 traffic conditions, both "With" and "Without" the Project were considered. Evaluations were I made of these future conditions and the ability of the street system to accommodate the trips evaluated. L_ The following are the principal findings of these analyses: i.._ (1) All of the study intersections currently operate at acceptable Levels of Service during the AM and PM peak hours: I. EI Camino Real & i gt Street ii. EI Camino Real & Main Street iii. EI Camino Real & Newport Avenue iv. Main Street & Newport Avenue v. Main Street & Prospect Avenue vi. Prospect Avenue & 1 st Street (2) Year 2020 traffic conditions "Without Project" were evaluated and it showed that acceptable LOS values for the daily traffic analyses and the six study L intersections are maintained. (3) A "worst case" analysis was used in evaluating the future traffic impacts at the study segments and intersections. A conservative growth rate was applied in the evaluation of future conditions and analyses were shown for lane geometries that presently exist. WPA Traffic Engineering El Camino Real MPAH Amendment (A Division of Willdan) 25 City of Tustin Job # 12680 1 (4) Under 'With Project' conditions where the MPAH Amendment (two lane on EI i Camino Real) is assumed to be in place, the street segment (daily traffic analyses) study intersections continue to operate at acceptable Levels of i Service. No significant traffic impacts are anticipated as a result of the El Camino Real Reclassification. (5) No significant traffic related impacts are expected for any jurisdictions outside of L the City of Tustin. L .L WPA Traffic Engineering El Camino Real MPAH Amendment (A Division of Willdan) 26 City of Tustin Job # 12680 APPENDIX A EXPLANATION OF INTERSECTION CAPACITY UTILIZATION AND LEVEL OF SERVICE APPENDIX A EXPLANATION OF INTERSECTION CAPACITY UTILIZATION The capacity of a, street is nearly always greater between intersections and less at intersections. The reason for this is that the traffic flows continuously between intersections and only part of the time at intersections. To study intersection capacity, a _ technique known as Intersection Capacity Utilization (ICU) has been developed. ICU analysis consists of (a) determining the proportion of signal time needed to serve each conflicting movement; (b) summing the times for the movements; and (c) comparing the: total time required to the time available._ For example, if for north -south .traffic the northbound traffic is 1,000 vehicles per hour, the southbound traffic is 800 vehicles per hour, and the capacity of either approach is 2,000 vehicles per hour of green, then northbound traffic is critical and requires 1,0000/2,000' or 50 percent of the signal time. If for the east -west traffic, 40 percent of the signal time is required, then it can be seen that the ICU is .50 plus 40, or 90 percent. When left -turn phases exist, they are incorporated into the analysis. As ICU's approach 100 percent, the quality of traffic service approaches Level of Service (.LOS) E, as defined in the Hiahwaw Cayacify Manual, Special Report 87, Highway Research Board, 1965. Level of Service is used to describe quality of traffic flow. Levels of Service A to C operate quite well. Level of Service D is typically the Level of Service for which an urban street is designed. Level of Service E is the maximum volume a facility can accommodate and will result in possible stoppages of momentary duration. Level of Service F occurs when a facility is overloaded and is characterized by stop-and=go traffic with stoppages of long duration. A description of the various Levels of Service appears on the following page. The ICU calculations assume that an intersection is signalized and that the signal is ideally timed. It is possible to have an ICU well below, 1.0, yet have severe traffic congestion. This would occur because one or more movements is not getting enough time to satisfy its demand, with excess time existing on other moves. Although calculating ICU for an unsignalized intersection is not necessarily valid, it can be performed with the presumption that a signal can be installed and the calculations show whether the geometrics are capable of accommodating the expected volumes. Capacity is often .defined in terms of roadway width. However, standard lanes have approximately the same capacity whether they are 11 foot or 14 foot lanes. Our data indicates that a typical lane, whether a through lane or a left -turn lane, has a capacity as high as approximately 2200 vehicles per lane per hour of green time. The 9985 Highway Capacity Manuaifound capacities of 1800 vehicles per Lane per hour of green time. These studies show that values in the 1600 to 1700 range should result in a conservative analysis.
