West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
1.0 INTRODUCTION
As Lead Agency, the City of San Clemente (City) prepared an Environmental Impact Report (EIR) for the Centennial General Plan (General Plan). The San Clemente City Council certified the Centennial General Plan Final Environmental Impact Report (Certified EIR) (State Clearinghouse No. 2013041021) and approved the General Plan on February 4, 2014.
Following certification of the EIR, the City adopted several General Plan Amendments to refine land use designations from the General Plan for various reasons, which were evaluated in subsequent addenda pursuant to the California Environmental Quality Act (CEQA). The Certified EIR and three subsequent addenda are described in more detail under Section 1.2, Previous Environmental Documents.
Currently, the City is proposing General Plan Amendment (GPA) 21-238, Land Use Plan Amendment (LUPA) 21-241, Specific Plan Amendment (SPA) 21-239, and Zoning Amendment (ZA) 21-240 (from herein referred to as the "West Pico Corridor Specific Plan Update and Architectural Overlay Expansion" or "project"). These amendments are proposed to:
• Change the land use designation of two parcels with the central-western portion of the City and expand the Architectural Overlay District to include additional parcels. • Update the West Pico Corridor Specific Plan (Specific Plan) to be consistent with the General Plan and City of San Clemente Local Coastal Program Land Use Plan (LUP), as required by State law, and expand the Specific Plan area to include additional parcels. • Update zoning to reflect the changes above.
Refer to Section 2.2, Proposed Project Characteristics, for a full description of the proposed project.
This fourth Addendum to the Certified EIR has been prepared in accordance with the provisions of the California Environmental Quality Act (CEQA) statutes (Public Resources Code 21000 et seq.); the CEQA Guidelines (14 California Code of Regulations, 15000 et seq.); and the rules, regulations, and procedures for implementing CEQA as adopted by the City of San Clemente.
The purpose of the Addendum to the Certified EIR is to determine whether the proposed project would result in new or substantially more severe significant environmental impacts compared with the impacts disclosed in the Certified EIR and subsequent addenda.
Additionally, project-specific impacts related to energy, vehicle miles traveled, tribal cultural resources, and wildfire were not specifically identified in the Certified EIR or subsequent addenda as these topics were not subject matter that required evaluation pursuant to the CEQA Guidelines at the time the documents were prepared. As such, this Addendum also analyzes the proposed project's impacts related to these topical areas.
As described in greater detail below, the City finds that the previously Certified EIR (SCH No. 2013041021) remains relevant in light of the proposed changes.

1.1 PROJECT LOCATION
The West Pico Corridor Specific Plan area is generally located in the western-central portion of the City in southern Orange County, stretching from the northern edge of North Beach Village to the San Diego Freeway (Interstate 5; I-5) in the vicinity of Avenida Pico; refer to Exhibit 1, Regional Vicinity, and Exhibit 2, Local Vicinity. Currently, the Specific Plan area encompasses approximately 80 acres of various land use designations, including Community Commercial 2 (CC 2), Neighborhood Commercial 1.2 (NC 1.2), Neighborhood Commercial 2 (NC 2), Light Industrial (LI), Heavy Industrial (Hl), Publicly Owned Open-Space (OS 1), and Public (P); refer to Exhibit 3, West Pico Corridor Specific Plan - Current Land Use Map.
The Specific Plan area is currently developed with mostly industrial and commercial uses with some residential uses. The Avenida Pico/l-5 interchange provides primary access to the Specific Plan area with secondary access via North El Camino Real, Avenida Pico, and Calle De Los Molinos.
The City's Architectural Overlay District shown on Exhibit 4, Current Architectural Overlay Area, encompasses areas in the Del Mar/T-Zone, North Beach, and Pier Bowl areas, and along portions of El Camino Real.

1.2 PREVIOUS ENVIRONMENTAL DOCUMENTS
1.2.1 2014 Certified EIR
On February 4, 2014, the San Clemente City Council: approved the Centennial General Plan, certified the Final Environmental Impact Report (State Clearinghouse No. 2013041021); approved a mitigation monitoring program; and adopted a statement of overriding considerations for the significant and unavoidable environmental impacts identified in the Certified EIR, namely Air Quality, Greenhouse Gas Emissions, Noise, and Transportation and Traffic.
1.2.2 2015 EIR Addendum No. 1
On November 3, 2015, the San Clemente City Council adopted GPA 15-049 and certified EIR Addendum No. 1 (2015 Addendum), pursuant to CEQA Guidelines Section 15164. GPA 15-049 clarified General Plan text and graphics, added and improved maps, and made changes to land use designations, standards, and policies. Changes under GPA 15-049 were classified into one of three groups: Groups A, B, or C. Group A amendments had no potential to impact the environment.
These items were limited to correcting maps and text to reflect EIR analysis and policy intent.
Several Group B amendments collectively reduced build-out commercial square footage up to 1,898,000 square feet and 64 housing units. There were only four Group C amendments that increased allowed development density of five parcels. These parcels were "infill" and developed with industrial and commercial uses. In total, Group C amendments added up to 212,000 square feet of allowed commercial uses and 54 housing units. Overall, the land use changes reduced the development density of General Plan build-out by 1,686,600 square feet of commercial use and 10 dwelling units. The amended build-out projections reduced traffic by more than 12,629 daily trips with a corresponding decrease in air emissions, greenhouse gas emissions, and roadway noise impacts.
1.2.3 2017 EIR Addendum No. 2
On September 5, 2017, the San Clemente City Council adopted GPA 15-331 and approved EIR Addendum No. 2(2017 Addendum) for the approval of the City of San Clemente 2013-2021 Housing Element Update (2013-2021 Housing Element Update). GPA 15-331 did not change the General Plan build-out projections evaluated in the Certified EIR and 2015 Addendum.
1.2.4 2019 EIR Addendum No. 3
On December 17, 2019, the San Clemente City Council adopted GPA 19-291 and SPA 19-292 (an update to the Pier Bowl Specific Plan), and approved EIR Addendum No. 3 (2019 Addendum). The project: 1) changed the land use designation of two parcels on Coronado Lane in the Pier Bowl area from Residential High (RH) to Mixed Use 4 (MU4) and added the Visitor-Serving Commercial District Overlay (VSCD), and 2) updated the Pier Bowl Specific Plan to be consistent with the General Plan and LUP. The land use change allowed 16,340 square feet of commercial use on the two subiect parcels, where the prior RH land use designation allowed residential uses only. The City projected that the land use change could add approximately 240 net new daily traffic trips and corresponding emissions and roadway noise to the impacts the Certified EIR identified for General Plan build-out.
However, these potential impacts were found to be offset by the land use changes the City adopted in 2015 with GPA 15-049 and the 2015 Addendum. Considering the prior build-out reductions and land use change, the City found GPA 19-291 reduced the General Plan build-out identified in the Certified EIR by 1,670,260 square feet of commercial use and reduced traffic by approximately 12,389 daily trips. Therefore, the GPA 19-291 shifted impacts from some parcels to other parcels Final May 2022
West Pico Corridor Specific Plan Update and Architectura! Overlay Expansion Centennial General Plan EIR Addendum No. 4
and the overall reduction of development potential in the General Plan more than offset project- level impacts. As a result, the 2019 Addendum concluded that GPA 19-291 and SPA 19-292 did not increase impacts previously found to be significant and unavoidable under the Certified EIR, and prior mitigation measures remained feasible to minimize impacts.
1.2.5 Documents Incorporated By Reference
CEQA Guidelines Section 15150 permits and encourages environmental documents to incorporate by reference other documents that provide relevant data and analysis. The documents referenced above are incorporated by reference herein and are considered part of the Final EIR. These documents are available for review upon request at the City of San Clemente Community Development Department located at 910 Calle Negocio, San Clemente, California 92673.
Final 8 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
2.0 DESCRIPTION OF PROPOSED PROJECT
2.1 ADDENDUM'S PURPOSE AND NEED
When an EIR has been certified for a project, CEQA Guidelines Section 15162 mandates that no subsequent or supplemental environmental review documentation shall be required unless one or more of the following events occurs:
1) Substantial changes are proposed in the project, which will require major revisions of the previous EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; 2) Substantial changes occur with respect to the circumstances under which the project is undertaken, which will require major revisions of the previous EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; or
3) New information of substantial importance, which was not known and could not have been known with the exercise of reasonable diligence at the time the previous EIR was certified as complete, shows any of the following:
A. The project will have one or more significant effects not discussed in the previous EIR;
B. Significant effects previously examined will be substantially more severe than shown in the previous EIR;
u. Mitigation measures or alternatives previously found not to be feasible would in fact be feasible, and would substantially reduce one or more significant effects of the project, but the project proponents decline to adopt the mitigation measure or alternative; or
D. Mitigation measures or alternatives which are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measure or alternative.
When none of the above events has occurred, yet minor technical changes or additions to the previously adopted negative declaration are necessary, an Addendum may be prepared (CEQA Guidelines Section 15164(b]).
As discussed below, none of the conditions described in CEQA Guidelines Section 15162 calling for preparation of subsequent environmental review have occurred. This Addendum supports the conclusion that the proposed project would result in minor or technical changes that do not result in any new significant environmental effects or a substantial increase in the severity of previously identified significant effects. In addition, as discussed below, the proposed project would not result in any new or substantially increased significant environmental impacts, no new mitigation Final 9 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
measures, and no new alternatives that would substantially reduce significant impacts. As a result, an Addendum is an appropriate CEQA document for analysis and consideration of the proposed project.
Circulation of an Addendum for public review is not necessary (CEQA Guidelines Section 15164[c]); however, the Addendum must be considered in conjunction with the adopted Final EIR by the decision-making body (CEQA Guidelines Section 15164[d]).
CEQA requires a comparative evaluation of a proposed project and alternatives to the project, including the "No Project" alternative. The EIR addressed a reasonable range of alternatives for the project. There is no new information indicating that an alternative that was previously rejected as infeasible is in fact feasible, or that a considerably different alternative than those previously studied would substantially reduce one or more significant effects on the environment.
2.2 PROPOSED PROJECT CHARACTERISTICS
The proposed project has three major components: 1) change the General Plan land use designation of two parcels, 2) expand the City's Architectural Overlay District, and 3) update the West Pico Corridor Specific Plan. These components are described in more detail below. The required discretionary actions for the project are listed in Section 2.3, Requested Discretionary Actions.
2.2.1 Proposed Land Use Change at 1510 Avenida De La Estrella The project proposes to modify two split-zoned industrial parcels located at 1510 Avenida De La Estrella (ANs 057-020-45 and 057-020-67) within the current Specific Plan area, comprising approximately 132,552 square feet of land area. The Heavy Industrial (HI) and LI land use designations currently run across the two parcels, resulting in "split zoning" where approximately 48,720 square feet of property is designated Light Industrial, with frontage to Avenida De La Estrella, and the remaining area of the two parcels is designated Heavy Industrial. The two parcels would be redesignated from Hi and LI to be entirely HI; refer to Exhibit 5, Proposed Land Use Change at 1510 Avenida De La Estrella.
The proposed redesignation would result in the following two changes to the allowed development of the property at 1510 Avenida De La Estrella:
• The maximum allowed density would increase from a 0.50 Floor Area Ratio (FAR) to 0.75 FAR, resulting in an allowable density increase of approximately 12,180 square feet. The maximum allowed density of the two parcels would change from approximately 87,235 square feet to 99,415 square feet.
• The land use change would make the existing non-conforming automobile towing and salvage use on the subject parcels a conforming use. The Specific Plan allows two conditionally permitted uses in HI zones that are not permitted in LI zones: 1) towing and salvage yards, and 2) concrete batch plants. It should be noted that the intent of the land use change is to modify a split zoned property and convert an existing non-conforming use into a conforming use. The land use change is not anticipated to intensify use of hazardous materials.
Final 10 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
2.2.2 Expansion of the City's Architectural Overlay District Pursuant to Municipal Code Section 17.56.020, Architectural (-A) Overlay District, the intent of the Architectural Overlay District is to establish a visually distinct district in San Clemente with the City's traditionai Spanish and Spanish Colonial Revival architectural style and a pedestrian orientation. The project proposes to expand the current Architectural Overlay District to include several properties that front primary circulation routes between the Downtown and Pier Bowl in order to integrate the architectural character of the visitor-serving districts; refer to Exhibit 6, Proposed Architectural Overiay Expansion Areas. Existing land use designations and zoning underlying the overlay district would remain the same.
2.2.3 Updates to the West Pico Corridor Specific Plan
The project proposes to update the development standards, permitted uses, design guidelines, and other content within the Specific Plan to be consistent with the General Plan and LUP, as required by State law, and to reflect the proposed land use change at 1510 Avenida De La Estrella (see Section 2.2.1, Proposed Land Use Change at 1510 Avenida De La Estreila).
Expansion of Specific Plan Area
Additionally, the current Specific Plan area includes a portion of the General Plan Los Molinos Focus Area. The project proposes to expand the Specific Plan area to include the entirety of the focus area; refer to Exhibit 7, West Pico Corridor Specific Pian - Proposed Expansion. By incorporating the entirety of the focus area, the Specific Plan would become a more useful and effective tool to implement General Plan goals and policies with updated development standards and design guidelines.
Four additional parcels at 1511 Avenida De La Estrella, 108 and 1607 Calle Lago, and 1623 North El Camino Real are also proposed to be incided in the Specific Plan area; refer to Exhibit 7.
Currently, these properties are zoned Light Industrial (LI) and the parceis on Calle Lago and North El Camino Real are also in the Mixed-Use (MU) Overlay District, where mixed use developments are allowed pursuant to Mixed Use 1 (MU 1) zoning standards. The Specific Plan's Light Industrial development standards and permitted uses would be applied to the four additional parcels; refer to Exhibit 8, West Pico Corridor Specific Plan - Proposed Land Use Map.

• No substantial changes are proposed in the project and there are no substantial changes in the circumstances under which the project will be undertaken that will require major revisions to the previous approved ND or MND or certified EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects. Also, there is no "new information of substantial importance" as that term is used in CEQA Guidelines Section 15162(a)(3). Therefore, the previously adopted ND or MND or previously certified EIR adequately discusses the potential impacts of the project without modification.
No substantial changes are proposed in the project and there are no substantial changes in the circumstances under which the project will be undertaken that will require major revisions to the previous approved ND or MND or certified EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects. Also, there is no "new information of substantial importance" as that term is used in CEQA Guidelines Section 15162(a)(3). Therefore, the previously adopted ND, MND or previously certified EIR adequately discusses the potential impacts of the project; however, minor changes require the preparation of an ADDENDUM Substantial changes are proposed in the project or there are substantial changes in the circumstances under which the project will be undertaken that will require major revisions to the previous ND, MND or EIR due to the involvement of significant new environmental effects or a substantial increase in the severity of previously identified significant effects. Or there is "new information of substantial importance," as that term is used in CEQA Guidelines Section 15162(a)(3). However, all new potentially significant environmental effects or substantial increases in the severity of previously identified significant effects are clearly reduced to below a level of significance through the incorporation of mitigation measures agreed to by the project applicant. Therefore, a SUBSEQUENT MND is required.
Substantial changes are proposed in the project or there are substantial changes in the circumstances under which the project will be undertaken that will require major revisions to the previous environmental document due to the involvement of significant new environmental effects or a substantial increase in the severity of previously identified significant effects.
Or there is "new information of substantial importance," as that term is used in CEQA Guidelines Section 15162(a) (3).
However, only minor changes or additions or changes would be necessary to make the previous EIR adequate for the proiect in the changed situation. Therefore, a SUPPLEMENTAL EIR is required.
Or there is "new information of substantial importance," as that term is used in CEQA Guidelines Section 15162(a)(3).
Therefore, a SUBSEQUENT EIR is required.

EVALUATION OF ENVIRONMENTAL IMPACTS:
1) A finding of "No New Impact/No Impact" means that the potential impact was fully analyzed and/or mitigated in the prior CEQA document and no new or different impacts will result from the proposed activity. A brief explanation is required for all answers except "No New Impact/No Impact" answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. A "No New Impact/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 New impact/No Impact" answer should be explained where it is based on project-specific factors as well as general standards (e.g., the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis). 2) A finding of "New Mitigation is Required" means that the project have a new potentially significant impact on the environment or a substantially more severe impact than analyzed in the previously approved or certified CEQA document and that new mitigation is required to address the impact. 3) A finding of "New Potentially Significant Impact" means that the project may have a new potentially significant impact on the environment or a substantially more severe impact than analyzed in the previously approved or certified CEQA document that cannot be mitigated to below a level of significance or be avoided. 4) A finding of "Reduced Impact" means that a previously infeasible mitigation measure is now available, or a previously infeasible alternative is now available that will reduce a significant impact identified in the previously prepared environmental document.
All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts.
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 Analyses 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. 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 proposed action.
c) Infeasible Mitigation Measures. Since the previous EIR was certified or previous ND or MND was adopted, discuss any mitigation measures or alternatives previously found not to be feasible that would in fact be feasible or that are considerably different from those previously analyzed and would substantially reduce one or more significant effects of the project, but the project proponents decline to adopt the mitigation measures or alternatives.
d) Changes in Circumstances. Since the previous EIR was certified or previous ND or MND was adopted, discuss any changes in the project, changes in circumstances under which the project is undertaken and/or "new information of substantial importance" that cause a change in conclusion regarding one or more effects discussed in the original document.

West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
Certified EIR Findings: The Certified EIR determined that implementation of the General Plan would not substantially alter scenic vistas or scenic highways upon implementation of General Plan policies and compliance with the Municipal Code. Although development in accordance with the General Plan could result in minor changes to existing views and ridgelines or the Pacific Ocean, development would be dispersed throughout the City and would be required to comply with City regulations and policies, including Municipal Code Chapter 15.40, Hillside Development, Chapter 15.44, Residential Development Control, Chapter 17.24, General Development Standards, and Chapter 17.68, Landscape Standards, General Plan policies, and other existing City policies that address the preservation of ridgelines, vistas, and scenic resources. Further, although the segment of 1-5 that traverses the City is not an officially designated scenic highway, both I-5 and State Route 1/El Camino Real are recognized as highways within the City that afford generous scenic views of hillsides, ridgelines, the City, and the Pacific Ocean. El Camino Real, which winds through the City roughly parallel to I-5 but also winds near the beach at the City's northwestern edge, is an officially designated scenic highway. Scenic corridors in the City, including I-5 and El Camino Real, and scenic resources near those corridors, are protected under General Plan Policy M-1.26, Major and Minor Scenic Corridors, among others, and Municipal Code development standards that limit the height and bulk of buildings. Upon compliance with existing regulations, impacts in regard to scenic vistas and scenic resources along a State scenic highway would be less than significant.
Additionally, the Certified EIR determined that implementation of the General Plan would not substantially alter the visual character of the City and its surroundings as most of the areas where land use changes would occur in accordance with the General Plan are already built out, and new or expanded uses would be required to comply with the General Plan policies and design guidelines and Municipal Code development standards that address visual characters and quality.
The Certified EIR determined that adherence to the design standards in the Municipal Code and other regulations ensured that light and glare from new development and redevelopment projects accommodated through the General Plan were minimized and that significant impacts would not occur.
2015 Addendum Findings: The 2015 Addendum analyzed impacts related to GPA 15-049 which reduced development density of General Plan build-out by up to 1,686,000 commercial square feet and 10 dwelling units. As analyzed, the 2015 Addendum concluded that no areas with density increases (Group C amendments) would obstruct views from a scenic vista. Additionally, development and redevelopment accommodated by GPA 15-049 is required to maintain the quality of view corridors by incorporating high quality design and materials in a project. Consistent with General Plan policies, projects must be designed to minimize impacts to view corridors and scenic vistas, be compatible with any adjacent historic resource in accordance with the Secretary of Interior's standards, and be in character with surrounding properties. Further, given the reduction in build-out potential, GPA 15-049 reduced potential light and glare impacts. Overall, impacts were determined to be less than significant and no new mitigation measures were required.
2017 Addendum Findings: The 2017 Addendum found that adoption of the 2013-2021 Housing Element Update under GPA 15-331 did not change the General Plan build-out projections evaluated in the Certified EIR and 2015 Addendum. Additionally, none of the revisions in the 2013- 2021 Housing Element Update would introduce new uses or different intensities along any scenic State highway than are already permitted. Any future development constructed consistent with the 2013-2021 Housing Element Update would continue to be required to comply with Municipal Code regulations, General Plan policies, and other existing City polices that protect scenic vistas Final 20
May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
and corridors, scenic resources, and aesthetic land use compatibility. The 2017 Addendum found no new impact would occur.
2019 Addendum Findings: The 2019 Addendum found that GPA 19-291 and SPA 19-292 did not change the type, scale, or intensity of development in the General Plan, except for changing two parcels on Coronado Lane from a Residential High density designation to Mixed Use. The two developed infill parcels are in the Pier Bowl Focus Area with sloped topography down to the ocean and properties that are mostly built out and graded. The parcels are not adjacent to a designated public view corridor or within or adjacent to a State scenic highway. Future development on the two parcels would also be required to comply with General Plan policies and Municipal Code standards related to architecture, neighborhood compatibility, visual impacts, urban design, and light and glare. Thus, the 2019 Addendum found no new aesthetic impacts would occur.
Proposed Project:
(a)-(b) Based on General Plan Figure NR-1, Aesthetic Resources Map (Citywide), no scenic vistas are located within or in the vicinity of the project site and thus, no impacts in this regard would occur.
As shown on Exhibit 4, the project site consists of portions of El Camino Real, which is an officially designated scenic highway. As shown on the Certified EIR Figure 5.1-3, Scenic Corridors Map, portions of Avenida Pico and El Camino Real are designated Major Urban Corridors and are located within the project site. Specifically, according to General Plan Figures NR-1 and NR-2, Aesthetic Resources Map (North Beach and Pier Bowl), several public view corridors are located within the project site affording views of the Pacific Ocean.
The project proposes to update the Specific Plan to be consistent with the General Plan and LUP and expand the Specific Plan area to include the entirety of the General Plan Los Molinos Focus Area, which would allow the Specific Plan to become a more useful and effective tool to implement General Plan goals and policies with updated development standards and design guidelines Additionally, as part of the updates to the Specific Plan, the project proposes to include four additional parcels at 1511 Avenida De La Estrella, 108 and 1607 Calle Lago, and 1623 North El Camino Real in the Specific Plan area. The Specific Plan's Light Industrial development standards and permitted uses would be applied to the four additional parcels. No site-specific development would occur at these additional parcels. As the project area is largely built out and no site-specific development is proposed, the proposed updates and expansion of the Specific Plan area would not result in new adverse impacts to scenic vistas or scenic resources along a designated scenic highway.
Additionally, a currently split zoned industrial property at 1510 Avenida De La Estrella would be redesignated from HI and Li to be entirely HI. This land use change would result in an allowable density increase of approximately 12,180 square feet and would make the existing non- conforming automobile towing and salvage use on the subject parcels a conforming use. As the project area is largely built out within an industrial area of the City that is not adjacent to scenic corridors or vistas, the proposed land use change would not result in new significant aesthetic impacts to scenic vistas or scenic resources along a designated scenic highway.
The project also proposes to expand the City's Architectural Overlay District to include several properties that front primary circulation routes between the Downtown and Pier Bowl in order to integrate the architectural character of the visitor-serving districts. The subject properties are not Final 21 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
adjacent to scenic corridors as shown on Certified EIR Figure 5.1-3. Existing land use designations and zoning underlying the overlay district would remain the same, and no site- specific development would occur. Thus, the proposed expansion of the City's Architectural Overlay District would not result in any new impacts to scenic vistas or scenic resources along a designated scenic highway. Overall, no new impacts have been identified and no new mitigation measures are required.
(c) As discussed above, the project would provide updates to the Specific Plan to be consistent with the General Plan and LUP, and expand the existing Architectural Overlay District to include additional parcels. As part of the updates to the Specific Plan, the project proposes to expand the Specific Plan area to include the entirety of the General Plan Los Molinos Focus Area, which would allow the Specific Plan to become a more useful and effective tool to implement General Plan goals and policies with updated development standards and design guidelines. Future development within the entirety of the General Plan Los Molinos Focus Area would also be consistent with the rest of the Specific Plan area. Additionally, as part of the updates to the Specific Plan, the project proposes to include four additional parcels at 1511 Avenida De La Estrella, 108 and 1607 Calle Lago, and 1623 North El Camino Real in the Specific Plan area. The Specific Plan's Light Industrial development standards and permitted uses would be applied to the four additional parcels. No site-specific development would occur; as such, no impacts would occur in this regard.
Additionally, a currently split zoned industrial property at 1510 Avenida De La Estrella would be redesignated from HI and LI to be entirely HI. This land use change would result in an allowable density increase of approximately 12,180 square feet and would make the existing non- conforming automobile towing and salvage use on the subject property a conforming use. No site development is proposed on the subject property as part of the project. However, future redevelopment of the site would be required to undergo separate environmental review under CEQA and comply with existing regulations governing scenic quality in the General Plan and Municipal Code.
The project also proposes to expand the City's Architectural Overlay District to include additional properties. As stated, existing land use designations and zoning underlying the overlay district would remain the same, and no site-specific development would occur. Further, upon project implementation, future development within the expanded overlay district would have more consistent architectural character within the visitor-serving areas of the Downtown and Pier Bowl areas. Thus, the proposed expansion of the overlay district would result in a beneficial impact with regards to enhancing the visual character of the Downtown and Pier Bowl areas.
Overall, compliance with General Plan Design Guidelines, Municipal Code standards, and General Plan policies would ensure impacts are reduced to less than significant levels. No new impacts are identified, and no new mitigation measures are required. (d) The project would not directly result in development that would introduce light and glare. The project would provide updates to the Specific Plan to be consistent with the General Plan and LUP and expand the Specific Plan area to incorporate several additional parcels, and expand the City's Architectural Overlay District to include additional parcels. No land use changes are proposed as part of these project components and future development would be required to comply with existing Municipal Code standards related to light and glare.
Additionally, a currently split zoned industrial property at 1510 Avenida De La Estrella would be redesignated from HI and Ll to be entirely HI. This land use change would result in an allowable Final 22 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
density increase of approximately 12,180 square feet and would make the existing non- conforming automobile towing and salvage use on the subject parcels a conforming use.
Because the project area is largely built out, lighting sources associated with the redesignated industrial property and future development in the Specific Plan area and expanded Architectural Overlay District would not substantially increase compared to existing conditions. Further, light and glare sources from future development within the project area would be required to comply with General Plan policies and design guidelines and Municipal Code development standards.
Specifically, General Plan policies NR-7.1, NR-7.2, and NR-7.3 require that land uses in the City use unobtrusive light so that the sky can be observed and enjoyed in a more natural state.
Additionally, Municipal Code Section 17.24.130, Lighting, requires exterior lighting to be energy- efficient and shielded or recessed so that direct glare and reflections are contained within the boundaries of the parcel, and are directed downward and away from adjoining properties and public rights-of-way. As such, no significant light and glare impacts would result from the proposed project beyond what was analyzed in the Certified EIR. No new impacts have been identified and no new mitigation measures are required.

Certified EIR Findings: The Certified EIR confirmed no areas within the City are identified as Prime Farmland, Unique Farmland, or Farmland of Statewide Importance as shown on maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency. The Certified EIR also confirmed there are no areas within the City zoned for agricultural use or parcels under a Williamson Act contract. Additionally, there are no areas within San Clemente designated forest land, timberland, or timberland production. Thus, the Certified EiR concluded no impacts in this regard would occur.
2015 Addendum Findings: As concluded in the Certified EIR, the 2015 Addendum also stated that there are no farmland areas within the City that are identified as Prime Farmland, Unique Farmland of Statewide Importance as shown on maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency. There are no areas in San Clemente zoned for agricultural use or parcels under a Williamson Act contract. Thus, GPA 15- 049 would not have a new or more significant impact to agriculture and forestry resources. 2017 Addendum Findings: Similar to the Certified EIR and 2015 Addendum, the 2017 Addendum found that no impacts would occur to agriculture and forestry resources. 2019 Addendum Findings: Similar to the Certified EIR, 2015 Addendum, and 2017 Addendum, the 2019 Addendum found that no impacts would occur to agriculture and forestry resources.
Proposed Project:
(a)-(e) The proposed project is located within the City boundaries and does not involve any land use changes related to agriculture, forest land, or timberland production. No new or substantially more severe impacts would occur, and no new mitigation measures are required.

Environmental Significant impacant Required Impact/No Reduced Issues: Documents Impact Impact
Where available, the significance criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following determinations. Would the project:
a. Conflict with or obstruct implementation Certified EIR of the applicable air quality plan? Pages 5.2-14
to 5.2-16
b. Violate any air quality standard of Certified EIR •

substantial pollutant concentrations? Pages 5.2-19
to 5.2-21
d. Create objectionable Result in other Certified EIR • emissions (such as those leading to Pages 5.2-22
odors) adversely affecting a substantial
number of people?
Certified EIR Findings: The Certified EIR concluded that the General Plan could be inconsistent with the Air Quality Management Plan because air pollutant emissions associated with build-out of the City could cumulatively contribute to the nonattainment designations in the South Coast Air Basin (SoCAB) and could increase the City's population and employment, which was not previously included in the regional emissions inventory when the General Plan was prepared.
Thus, impacts were determined to be significant and unavoidable.
The Certified EIR concluded that build-out of the General Plan could result in construction-related air quality impacts and build-out emissions could exceed the South Coast Air Quality Management District (SCAQMD) regional significance thresholds. In accordance with the SCAQMD methodology, emissions that exceed the regional significance thresholds could cumulatively contribute to the nonattainment designations of the SoCAB. Mitigation Measures 2-1 through 2-3 were included to reduce impacts in this regard; however, impacts remained significant and unavoidable.
The Certified EIR also concluded that the General Plan build-out could generate long-term emissions that could exceed the SCAQMD's significance thresholds and could cumulatively Final 25 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
contribute to the nonattainment designations of the SoCAB. General Plan policies and implementation actions require future development to apply SCAQMD air quality mitigation measures and reduce air quality impacts to the extent feasible. However, operational-related air quality impacts associated with future development of the General Plan were found to be significant and unavoidable.
The Certified EIR concluded that growth from the General Plan could generate new sources of odors and place sensitive receptors near existing sources of odors. Industrial land uses have the potential to generate objectionable odors. Examples of industrial projects are wastewater treatments plants, compost facilities, landfills, solid waste transfer stations, fiberglass manufacturing facilities, paint/coating operations (e.g., auto body shops), dairy farms, petroleum refineries, asphalt batch plants, chemical manufacturing, and food manufacturing facilities. The Certified EIR found odors from industrial land uses would have a less than significant impact with the implementation of Mitigation Measure 2-4.
2015 Addendum Findings: Given the reduction in General Plan build-out potential under GPA 15-049, the 2015 Addendum found that GPA 15-049 reduced potential traffic related impacts by more than 13,000 average daily trips with a corresponding decrease in air emissions. As such, implementation of GPA 15-049 was found to have no new impacts or reduced impacts compared to the Certified EIR.
2017 Addendum Findings: The 2017 Addendum found that adoption of the 2013-2021 Housing Element Update would not increase the severity of the General Plan's significant and unavoidable air quality impacts because it would not further increase the population and/or employment growth associated with build-out of the General Plan, beyond that analyzed in the Certified EIR. 2019 Addendum Findings: The 2019 Addendum found that GPA 19-291 and SPA 19-292 allowed 16,340 square feet of commercial use on two subject parcels, where the prior land use designation allows residential uses only. This land use change could add approximately 240 net new daily traffic trips, which could generate additional emissions. However, the City adopted GPA 15-049 in 2015 which reduced the General Plan build-out by up to 1,686,600 commercial square feet and 10 dwelling units. This reduced development related impacts, including air quality. The amended build-out projections reduced traffic by more than 12,629 average daily trips and decreased air emissions to an extent that more than offset impacts from GPA 19-291 and SPA 19-292. Therefore, the project shifted impacts from some parcels to other parcels and the overall reduction of development potential in the General Plan more than offset air quality emissions associated with GPA 19-291 and SPA 19-292. Thus, the 2019 Addendum found no new impacts would occur and prior mitigation measures remained applicable.
Proposed Project:
(a) The proposed project would not change the type, scale, or intensity of development contemplated in the General Plan and previously analyzed in the Certified EIR, except for changing two split zoned parcels from HI and Ll to entirely HI. The land use change is intended to modify the split zoned parcels and would make the existing non-conforming automobile towing and salvage use on the subject parcels a conforming use. No site specific development is proposed as part of the project. As detailed in the West Pico Corridor Specific Plan Update and General Plan Amendment Transportation Analysis (Transportation Analysis), prepared by Michael Baker International and dated March 15, 2022, the land use change would add approximately 80 net average daily trips and associated emissions; refer to Attachment 1, Transportation Analysis. However, GPA 15-049 reduced the General Plan build-out by up to Final 26 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
1,686,600 commercial square feet and 10 dwelling units. The amended build-out projections reduced traffic by more than 12,629 daily trips and decreased air emissions to an extent that more than offsets impacts from the proposed project's 80 net average daily trips. As such, the project has no new impacts regarding plan consistency.
(b) The project proposes to update the Specific Plan to be consistent with the General Plan and LUP and include additional parcels within the Specific Plan area. Additionally, one land use change is proposed within the Specific Plan area, which would modify two split zoned industrial parcels and redesignate them from LI and HI to entirely HI. The intent of the land use change is to make the existing non-conforming automobile towing and salvage use on the subject parcels a conforming use. No site development is proposed as part of the project. Future development on the subject parcels would also be required to undergo separate environmental review under CEQA. Further, it is acknowledged that Mitigation Measures 2-1 through 2-3 would still apply to the project.
The proposed project would also expand the City's existing Architectural Overlay District to integrate the architectural character of the visitor-serving districts to additional parcels in the Downtown and Pier Bowl. The overlay district expansion would not result in any emissions. As such, the project would not result in any new or potentially adverse construction-related air quality impacts not previously considered and addressed in the Certified EIR. Implementation of Mitigation Measures 2-1 through 2-3 would also reduce impacts in this regard to less than significant levels.
While the proposed project would not directly propose any construction, long-term operational impacts from stationary sources (e.g., mechanical equipment, landscaping, and heating, ventilation, and air conditioning [HVAC] equipment) would be similar to existing conditions and would not substantially increase operational emissions. Further, as detailed in the Transportation Analysis, the proposed project is anticipated to generate approximately 80 average daily trips. As such, operational air quality impacts from mobile sources would not be significant. Additionally, GPA 15-049 reduced the General Plan build-out and the reduction of development potential would offset air quality impacts associate with the proposed project. As such, no new impacts are identified and no new mitigation measures are required. (c) The proposed project would redesignate two split zoned parcels from LI and HI to entirely HI.
The land use change would make the existing non-conforming automobile towing and salvage use on the subject parcels a conforming use. The land use change would increase the maximum allowable density at the property by approximately 12,180 square feet and thus, has the potential to generate new sources of air pollutants. Note, land uses identified in Certified EIR Table 5.2-10, CARB Recommendations for Siting New Sensitive Land Uses, for siting sensitive uses are not proposed by the project. CO emissions are a function of vehicle idling time, meteorological conditions, and traffic flow. Based on the Transportation Analysis, the proposed land use change would generate 80 additional average daily trips. Given the nominal net increase of trips, air quality impacts to the sensitive receptors would not be significant in regards of CO emissions and toxic air containments. Additionally, GPA 15-049 reduced the General Plan build-out and the reduction of development potential would offset air quality impacts associate with the proposed project. Therefore, the project would result in no new impacts; and no new mitigation measures are required.
(d) As stated in the Certified EIR, industrial uses would have less than significant impacts with regards to odors upon implementation of Mitigation Measure 2-4 and compliance with SCAQMD Rule 402. While the proposed land use change would redesignate the split zoned property from Final 27 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
LI and HI to entirely HI, the intent of the land use change is to modify a split zoned property and convert an existing non-conforming use into a conforming use. The Specific Plan area is also located in an industrial area and thus, potential future redevelopment of the industrial property would not introduce new sources of odors that adversely affect a substantial number of people.
Upon implementation of Mitigation Measure 2-4 and compliance with SCAQMD Rule 402, impacts would be less than significant. Therefore, no new impacts would occur, and no new mitigation is required.

Certified EIR Findings: The Certified EIR states that sensitive species such as the California gnatcatcher can occur in coastal scrub habitats on hillsides. Construction activities in area that adjoin suitable habitat for sensitive species could indirectly impact the species as a result of disturbance during the nesting season. As such, development within these areas could result in potentially significant impacts. Applicants for future development projects that disturbed undeveloped land would be required to acquire a qualified biologist to prepare a biological resources survey to assess development impacts to any existing biological resources within the development area (Mitigation Measure 3-1). In the event that a future development project has the potential to affect listed endangered or threatened species, applicants would be required to obtain written authorization from the U.S. Fish and Wildlife Service that the grading or construction activities is in compliance with regulations on the "take" of such species (Mitigation Measure 3-2).
Upon compliance with Mitigation Measures 3-1 and 3-2, the Certified EIR determined that impacts to candidate, sensitive, or special status species would be less than significant.
Additionally, the Certified EIR identified sensitive habitats within the City, including coastal sage scrub, coast live oak woodland and forest, and riparian communities such as mule fat scrub, southern willow scrub, and southern arroyo willow riparian forest. The majority of these sensitive habitats occur in land designated as Open Space-Publicly Owned or Open Space-Privately Owned. The Certified EIR determined that implementation of General Plan Natural Resources Element Policies NR-1.01, NR-1.02, NR-1.03, NR-1.04, NR-1.05, and NR-1.06, as well as Coastal Element Policies C-2.02, C-2.05, C-2.06, C-2.07, C-2.08, C-2.09, C-2.10, C-2.11, and C-2.12, would reduce impacts to sensitive habitats. Future development projects that disturb undeveloped land would also be required to comply with Mitigation Measures 3-1 and 3-2. As such, the Certified EIR found that impacts to sensitive habitats would be reduced to less than significant: levels.
Deshecha Canada stream/channel, the Segunda Deshecha Canada stream/channel, other coastal streams, tributaries of the San Mateo Creek, including Cristianitos Canyon, and estuarine/marine areas along the Pacific Ocean. The Certified EIR included Mitigation Measures Final 29 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
3-3 through 3-5 to reduce potential impacts associated with build-out of the General Plan to jurisdictional resources to less than significant levels.
Major wildlife movement corridors identified in the Certified EIR are located along the northern and northeastern boundaries of the City, which adjoin the Cristianitos Canyon habitat linkage, and are designated by the General Plan as Open Space-Privately Held. The Certified EIR determined that future development projects within designated open space or identified as a major linkage/corridor be required to prepare a habitat connectivity evaluation (Mitigation Measure 3-6) to reduce impacts to less than significant levels.
According to the Certified EIR, the City is located within the Plan Area of the Orange County Southern Subregion Habitat Conservation Plan (HCP), which serves as an HCP for the "take" of selected federally threatened species, including the California gnatcatcher. The HCP identifies certain areas within the City as current preserves or protected habitat reserves for federally threatened species.
2015 Addendum Findings: The 2015 Addendum found that implementation of GPA 15-049 was not expected to result in new significant impacts or substantially increase previously studied and mitigated impacts. Overall, GPA 15-049 reduced General Plan build-out potential. Only Group C amendments increased allowed infill development of commercial and industrial uses in the City.
These subject properties have no known biological resources on-site and are not in conflict with an adopted Habitat Conservation Plan or Natural Community Conservation Plan. Thus, the 2015 Addendum found that impacts were determined to be less than significant in this regard and no new mitigation measures were identified.
2017 Addendum Findings: The 2017 Addendum found that adoption of the 2013-2021 Housing Element Update would not result in any new impacts to biological resources because no additional build-out beyond that analyzed in the Certified EIR would occur. Additionally, activities implemented under the 2013-2021 Housing Element Update would be consistent with the Habitat Conservation Plan and the City's Coastal Element and all existing policies and regulations would apply to future housing development. The 2017 Addendum found that no new impacts would occur.
2019 Addendum Findings: The project did not change the type, scale, or intensity of development in the General Plan, except for changing two parcels on Coronado Lane from a Residential High density designation to Mixed Use. The subject parcels are in the Pier Bowl Focus Area, which is mostly built out and graded. The two parcels on Coronado Lane are also developed infill lots in an urbanized area. No sensitive biological resources are located in the area. Thus, it was found that no new impacts would occur.
Proposed Project:
(a) The proposed project would update the Specific Plan to be consistent with the General Plan and LUP, and would expand the current Specific Plan area to include the entirety of the Los Molinos Focus Area. The project would not change the type, scale, or intensity of development contemplated in the General Plan and previously analyzed in the Certified EIR, with the exception of one split zoned industrial property located at 1510 Avenida De La Estrella. The project proposes to redesignate the property from HI and Li to entirely HI to modify the split zone and convert an existing non-conforming automobile towing and salvage use to a conforming use. As such, the project would not directly result in physical environmental impacts to sensitive habitat.
Additionally, future development within the project area would require separate environmental Final 30 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
review under CEQA on a project-by-project basis. Where applicable, future developments would be required to comply with Mitigation Measures 3-1 and 3-2, as stated within the Certified EIR.
As such, no new impacts to special status species would occur, and no new mitigation measures are required.
The proposed project would also expand the City's existing Architectural Overlay District to include properties that front primary circulation routes between the Downtown and Pier Bowl. The expansion of the overlay district would not result in physical environmental impacts, including impacts to special status species. As such, no new impacts are identified, and no new mitigation measures are required.
(b) The Specific Plan area and Architectural Overlay District area are predominantly built out and located in urbanized areas of the City. There are no sensitive habitats within the project area.
Thus, the project would have no substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, and regulations or by the California Department of Fish and Game or U.S. Fish and Wildlife Service. No new impacts would occur, and no new mitigation measures are required. Mitigation Measures 3-1 and 3-2 would remain applicable:
(c) No land use changes are proposed by the project that could impact federally protected wetlands. As stated, one land use change is proposed to modify a split zoned industrial property from Hi and Ll to entirely HI. The site is currently developed with an automobile towing and salvage use and thus, does not have any federally protected wetlands on-site. Accordingly, no new impacts are identified, and no new mitigation measures are required. (d) The Specific Plan area and Architectural Overlay District are located in urbanized areas of the City and have no areas designated as open space or identified as a major linkage/corridor. Thus, no new impacts would occur, and no new mitigation measures are required. (e)-(f) The proposed project would not conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance. There are no known biological resources within the project area. As stated, the project would not change the land use designations or the type, scale, or intensity of development contemplated in the General Plan and previously analyzed in the Certified EIR, with the exception of changing the land use designation of one property located at 1510 Avenida De La Estrella from HI and Ll to entirely HI. However, this industrial property is located in an urbanized and predominantly built out area of the City and would not conflict with the HCP nor any local policies or ordinances protecting biological resources. Thus, no new impacts have been identified, and no new mitigation measures are required.

Certified EIR Findings: According to the Certified EIR, there are multiple historic resources within the City that are listed or eligible for listing on the National Register of Historic Resources, California Register of Historical Resources, and/or local register. However, implementation of the General Plan in itself would not involve demolishing or materially altering any historic resources within San Clemente. Additionally, compliance with existing General Plan policies and Municipal Code standards regarding historic resources ensured impacts would be reduced to less than significant levels.
The Certified EIR concluded that the City is considered potentially sensitive for archaeological resources. Additionally, ground disturbance from development of projects pursuant to the General Plan could damage fossils buried in soils. General Pan Policy NR-3.01 requires an assessment and mitigation of potential project impacts to archaeological and paleontological resources for projects requiring environmental review under CEQA, and General Plan Policies NR-3.02 and
3.03 require notification and inventory of archaeological and paleontological resources.
Additionally, the Certified EIR recommended Mitigation Measure 4-1, which would require future developers to prepare archaeological resources assessments evaluating a project's potential impacts on known and unknown archaeological resources.
The Certified EIR determined that, because the City is considered potentially sensitive for archaeological resources, human remains could be buried in soils. California Health and Safety Cade Section 7050.5 requires that if human remains are discovered within the project site, disturbance of the site would be required to stop and remain halted until the coroner has conducted an investigation and made recommendations to the person responsible for the excavation. In the event that the coroner determines that the remains are not subject to his or her authority and if the coroner recognizes or has reason to believe the human remains to be those of a Native American, he or she shall contact, by telephone within 24 hours, the Native American Heritage Commission.

2015 Addendum Findings: The 2015 Addendum found that implementation of GPA 15-049 would not demolish or materially alter historic resources. There were only four Group C amendments that increased allowed density of five infill developed parcels with commercial and industrial uses. Development and redevelopment in the area is required to be consistent with any surrounding historic resources by incorporating high quality design and materials in the project.
Thus, impacts to historical resources were determined to be less than significant.
Group C amendments also had potential to impact archaeological and paleontological resources and human remains; however, compliance with existing federal, State, and local regulation reduced such impacts. Additionally, projects are subject to the same mitigation measures that reduced General Plan impacts to less than significant levels. Thus, impacts in this regard were determined to be less than significant and no new mitigation measures were required. 2017 Addendum Findings: The 2017 Addendum found that adoption of the 2013-2021 Housing Element Update would not result in any new impacts to cultural resources because no additional build-out beyond that analyzed in the Certified EIR would occur. Thus, the 2017 Addendum found no new impacts would occur.
2019 Addendum Findings: The 2019 Addendum determined that the land use changes on two parcels on Coronado Lane would not impact any historical resources within the City. Additionally, development is subject to a discretionary review process under CEQA in which project-level impacts are evaluated and mitigated if necessary. Thus, that project was found not to have new impacts on archaeological or paleontological resources or human remains.
Proposed Project:
(a) The proposed project would update the Specific Plan to be consistent with the General Plan and LUP and expand the existing Architectural Overlay District to include additional parcels. No site-specific development is proposed, and the project would not directly result in impacts to existing structures and resources. The project would not change the type, scale, or intensity of development previously contemplated in the General Plan and analyzed in the Certified EIR, with the exception of modifying a split zoned industrial property located at 1510 Avenida De La Estrella from Hi and Ll to entirely HI. The subject property is currently developed as an automobile towing and salvage use with no historical resources on-site or adjacent to the subject property. Therefore, no new impacts to historic resources would occur and no new mitigation measures are required for the proposed project.
(b) As stated, the proposed project would not change the type, scale, or intensity of development contemplated in the General Plan and previously analyzed in the Certified EIR, with the exception of modifying a split zoned industrial property from HI and LI to entirely H!. While the proposed land use change would increase the maximum allowed density of the industrial property by approximately 12,180 square feet, the intent of the land use change is to modify a split zoned property and convert an existing non-conforming use into a conforming use. No site-specific development is proposed. Therefore, no new impacts have been identified and no new mitigation measures are required for the proposed project. Mitigation Measure 4-1 from the Certified EIR would still be applicable to the proposed project.
(c) The proposed project would not change the type, scale, or intensity of development contemplated in the General Plan and previously analyzed in the Certified EIR, with the exception of modifying a split zoned industrial property from HI and LI to entirely HI. While the proposed land use change would increase the maximum allowed density of the industrial property by Final 33 May 2022

Certified EiR Findings: The Certified EiR did not evaluate energy impacts as it was not required in the CEQA Guidelines at the time the Certified EIR was prepared in 2013. 2015 Addendum Findings: The 2015 Addendum did not evaluate energy impacts as it was not required in the CEQA Guidelines at the time the 2015 Addendum was prepared in 2015. 2017 Addendum Findings: The 2017 Addendum did not evaluate energy impacts as it was not required in the CEQA Guidelines at the time the 2017 Addendum was prepared in 2017. 2019 Addendum Findings: The 2019 Addendum did not evaluate energy impacts as it was not required in the CEQA Guidelines at the time the 2019 Addendum was prepared in 2019.
Proposed Project:
(a)-(b) As stated, the Certified EIR and subsequent addenda did not evaluate energy impacts as it was not required in the CEQA Guidelines at the time the environmental documents were prepared.
Therefore, the proposed project's impacts, as currently proposed, is discussed below.
Public Resources Code Section 21100(b)(3) and CEQA Guidelines Section 15126.4 require EIRs to describe, where relevant, the wasteful, inefficient, and unnecessary consumption of energy caused by a project. Thus, the effect of energy usage could have been raised in 2013 when the City considered the EIR. A challenge to an EIR must be brought within 30 days of the lead agency's notice of approval. (Pub. Resources Code, § 21167[b].) Under Public Resources Code Final 34 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
Section 21166(c), an agency may not require a supplemental environmental review unless new information, which was not known and could not have been known at the time the EIR was approved, becomes available. After a project has been subjected to environmental review, the statutory presumption flips in favor of the project proponent and against further review. (Moss v.
County of Humboldt [2008] 162 Cal.App.4th 1041, 1049-1050.) "[S]ection 21166 comes into play precisely because in-depth review has already occurred [and] the time for challenging the sufficiency of the origina! EIR has long since expired " (Id., 1050.) The proposed project would provide updates to the Specific Plan to be consistent with the General Plan and LUP and expand the existing Architectural Overlay District to include additional parcels.
The Specific Plan update and expansion of the City's Architectural Overlay District would not result in any energy consumption and would not conflict with a State or local renewable energy or energy efficiency plan.
However, the project proposes one land use change on a split zoned industrial property at 1510 Avenida De La Estrella within the Specific Plan area to redesignate the property from HI and LI to be entirely hi. The redesignation would increase the property's maximum allowed density by approximately 12,180 square feet. The intent of the land use change is to make the existing non- conforming automobile towing and salvage use on the subject parcels a conforming use. No site development is proposed as part of the project and future redevelopment of the industrial property would be required to undergo separate environmental review under CEQA. Future redevelopment would also be required to comply with mandated energy efficiency programs and regulations included in the California Building Energy Efficiency Standards (Title 24) of the California Building Code (CBC). The standards require developers to provide windows, insulation, lighting, ventilation systems, and other features that reduce energy consumption in homes and businesses.
Additionally, the 2019 California Green Building Standards Code (California Code of Regulations, Title 24, Part 11), commonly referred to as CALGreen, went into effect on January 1, 2017.
CALGreen requires that new buildings employ water efficiency and conservation, increase building system efficiencies, divert construction waste from landfills, and incorporate electric vehicles charging infrastructure. Additionally, the City adopted the City of San Clemente Climate Action Plan (CAP) in April 2012. The CAP is linked to the General Plan and the City of San Clemente Sustainability Action Plan (SAP), adopted in 2010. The CAP represents further implementation of the SAP's established goals through a focus on reducing greenhouse gas emissions over time. The CAP is the City's strategy to actively anticipate and plan for the future and is first step in the City's development of a long range, comprehensive plan to move from business-as-usual growth practices to an environmentally and economically sustainable growth model. The CAP provides a roadmap to reduce the City's municipal and community emissions.
Future development would be required to adhere to all applicable federal, State, and local requirements for energy efficiency, including Title 24 standards, CALGreen, and the City's CAP.
Overall, the proposed project would not result in the inefficient, wasteful, or unnecessary consumption of energy and a less than significant impact would occur.

Certified EIR Findings: According to the Certified EIR, San Clemente does not lie within an Alquist-Priolo Earthquake Fault Zone listed by the U.S. Geological Survey. Thus, the Certified EIR found that no impacts would occur in this regard.
The City is located in a seismically active region and strong ground shaking is likely to occur.
Build-out of the General Plan could increase the number of residential and nonresidential structures in the City. However, each development project considered for approval by the City under the General Plan is required to comply with seismic safety provisions of the California Building Code (CBC) and have a geotechnical investigation conducted for the affected project site. Thus, impacts were determined to be less than significant.
Parts of the City are in zones of required investigation for liquefaction hazard designated by the California Geological Survey; refer to Certified EIR Figure 5.5-5, Seismic Hazard Zones. The zones of required investigation are mostly concentrated along the coast and in lower-elevation portions of Cristianitos, Prima Deshecha, and Segunda Deshecha Canyons, and some tributary canyons to those three canyons. Site-specific geotechnical investigations would be required to evaluate the potential for liquefaction and other seismic ground failure and to provide recommendations to reduce such hazards. Future projects would also be required to comply with CBC standards. Thus, impacts were determined to be less than significant.
Much of the land surface in the City consists of areas subject to landslides; refer to Certified EIR Figure 5.5-3, Landslides Map. Additionally, much of the City, including most of the City northeast of 1-5, are designated Zones of Required Investigation for earthquake-induced landslides; refer to Certified EIR Figure 5.5-5, Seismic Hazard Zones. However, build-out of the General Plan would be required to comply with seismic safety provisions of the CBC and prepare site-specific soil engineering and engineering geology report to provide slope stability analyses for suspect slopes.
The Certified EIR found that upon compliance with the CBC and implementation of recommended geotechnical design measures, future development accommodated by the General Plan would result in less than significant impacts in this regard.
The Certified EIR determined build-out of the General Plan could result in soil erosion. However, future development projects located on parcels one acre or larger would be required to implement a Stormwater Pollution Prevention Plan (SWPPP) to obtain coverage under a General Construction Activity Permit issued by the State Water Resources Control Board (SWRCB) and implement Best Management Practices (BMPs) related to soil erosion. BMPs could include erosion control measures, wind erosion control measures and sediment control measures.
Final 37 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
Additionally, construction activities associated with future development would be required to comply with Municipal Code 15.36 Excavations and Grading, Article XII Erosion Control.
Consequently, impacts regarding soil erosion or the loss of topsoil were determined to be less than significant.
According to the Certified EIR, parts of the City are located in zones of required investigation for liquefaction hazards and landslide hazards designated by the California Geological Survey.
Expansive soil hazards could also potentially occur within the City. However, ground subsidence is not considered a major hazard in the City. Future developments accommodated by the General Plan would be required to prepare site-specific geotechnical investigations to evaluate potential geotechnical hazards associated with liquefaction, landslide, and expansive soils. Each project would be required to comply with recommendations in the geotechnical investigation report for its project site. Consequently, impacts were determined to be less than significant.
The City may contain significant, nonrenewable, paleontological resources and has a high sensitivity for paleontological resources. Abundant fossils occur in several rock formations in the City, including the Capistrano Formation. Future build-out of the General Plan would be required to comply with General Plan Policies NR-3.02 and NR-3.03 regarding the management of artifacts and the notification and inventory of archaeological and paleontological resources. Additionally, Mitigation Measure 4-2 requires applicants for development permits to provide studies by qualified paleontologists assessing the sensitivity of sites for buried paleontological resources. Upon compliance with the General Plan policies and implementation of Mitigation Measure 4-2, impacts in this regard were determined to be less than significant. 2015 Addendum Findings: The 2015 Addendum found that Group C amendments under GPA 15-049 increased the maximum allowed density on a limited number of parcels in the form of infill/intensification in already developed areas. Future projects would be required to have a geotechnical investigation conducted to evaluate site soils for various geotechnical issues and implement recommended remediation measures. Additionally, future projects would be required to connect with the City's public sewer system so no septic tanks or alternative wastewater systems would be needed or used. Overali, the 2015 Addendum concluded that GPA 15-049 would not result in new or more significant impacts.
2017 Addendum Findings: The 2017 Addendum found that adoption of the 2013-2021 Housing Element Update would not increase the overall build-out of the City, and therefore would not result in increased exposure of persons and buildings to geological hazards beyond what was previously analyzed in the Certified EIR. Further, all projects developed pursuant to the 2013-2021 Housing Element Update would be required to complete geotechnical investigations and implement any remedial recommendations, prepare a SWPPP and implement erosion control measures, and be subject to the California Building Code. Additionally, future projects would be required to connect with the City's public sewer system so no septic tanks or alternative wastewater systems would be needed or used. The 2017 Addendum found no new impact would occur. 2019 Addendum Findings: The 2019 Addendum stated that the two land use changes on Coronado Lane are developed infill lots in the Pier Bowl Focus Area. No site specific operations or development of any kind was proposed. Thus, the 2019 Addendum found no new impacts would occur.

Certified EIR Findings: The Certified EIR concluded that General Plan build-out could contribute to global climate change through direct and indirect GHG emissions. The increase in GHG emissions is based on the difference between existing land uses and land uses associated with build-out of the General Plan as well as an estimate of population and employment within the City by 2035. To achieve the local goals identified by the California Air Resources Board's 2008 Scoping Plan, the City prepared a CAP with the General Plan. The CAP identified and evaluated feasible and effective policies to reduce GHG emissions in order to reduce energy costs, protect air quality, and improve the economy and the environment. However, no additional measures were available to reduce GHG emissions associated with the General Plan build-out and impacts were determined to be significant and unavoidable.
2015 Addendum Findings: The 2015 Addendum found that implementation of GPA 15-049 reduced potential traffic related impacts by more than 13,000 average daily trips with a corresponding decrease in air emissions, greenhouse gas emissions, and roadway noise impacts.
This is due to the fact that GPA 15-049 reduced development intensity of General Plan build-out.
Overall, Group B amendments reduced development and more than offset density increases from Group C amendments, resulting in less development over the build-out period. Therefore, implementation of GPA 15-049 was found to result in no new impacts or reduced impacts as compared to General Plan build-out.
Final 40 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4 |
2017 Addendum Findings: Adoption of the 2013-2021 Housing Element Update did not increase the severity of GHG emissions impacts because it did not result in new development or transportation that could emit additional GHG emissions beyond those already assumed and analyzed. Further, the policies of the General Plan and the CAP aimed at reducing emissions would remain in effect and would apply to any future housing development constructed consistent with the 2013-2021 Housing Element Update. Thus, the 2017 Addendum found no new impacts would occur.
2019 Addendum Findings: As stated, the two land use changes analyzed in the 2019 Addendum allowed 16,340 square feet of commercial uses where the prior land use designation allowed residential uses only. The land use change added approximately 240 ptoential net new daily traffic trips with additional GHG emissions. However, several land use changes were adopted in 2015 (i.e., GPA 15-049) that reduced the General Plan build-out, which more than offset GHG emission impacts associated with GPA 19-291 and SPA 19-292. As a result, the 2019 Addendum found no new impacts would occur and prior mitigation measures remain applicable.
Proposed Project:
(a)-(b) The project does not change the type, scale, or intensity of development contemplated in the General Plan and previously analyzed in the Certified EIR, except for modifying the split zoned industrial property from LI and HI to entirely HI. No site development is proposed as part of the project. The land use change would increase the maximum allowable density of the subject property by approximately 12,180 square feet and would add approximately 80 net new average daily trips. This additional growth would generate emissions that would contribute to climate change. However, the project is within the scope of impacts identified and mitigated in the Certified EIR. In 2015, the City adopted GPA 15-049 that reduced General Plan build-out by up to 1,686,600 commercial square feet and 10 dwelling units. The amended build-out projections reduced traffic by more than 12,629 daily trips and decreased air emissions to an extent that more than offsets impact from the proposed project. Consequently, operational GHG emissions impacts associated with the proposed project would be less than significant. Additionally, future redevelopment would be required to comply with mandated energy efficiency programs and regulations, including Title 24 of the CBC and CALGreen, both of which were recently adopted or updated since the Certified EIR was certified. As such, no new impacts are identified, and no new mitigation measures are required.

Certified EIR Findings: The Certified EIR determined that with adherence with applicable federal, State, and local regulatory requirements, including the California Accidental Release Prevention (CalARP) program managed by the Orange County Fire Authority (OCFA), Municipal Code Chapter 8.36, Hazardous Materials, and General Plan Policies S-6.01 to 6.06, impacts associated with the transport, use, and disposal of hazardous materials in the City, including would be as han gatest win the pies euros ande
those from the Orange County Environmental Management Agency, OCFA, Municipal Code, and General Plan.
The Certified EIR determined that the closest airport (i.e., John Wayne Airport) is located approximately 25 miles to the northwest of the City. There are no public or public use airports in, or in the general vicinity of San Clemente. As such, the Certified EIR found no impact in this regard would occur.
The Certified EIR determined that future development accommodated through the General Plan would not interfere with implementation of the City's Multi-Hazard Emergency Plan, operation of the City Emergency Operations Center and the OCFA Emergency Command Center, or City's participation in the Standardized Emergency Management System. As such, implementation of the General Plan would result in less than significant impacts in regard to applicable emergency response or evacuation plan.
2015 Addendum Findings: Group C amendments under GPA 15-049 were limited to a specific area and scope that is not expected to substantially increase the transport, use, or disposal of hazardous materials previously identified and mitigated for in the Certified EIR. The General Plan contains policies and programs to ensure compliance with federal, State, and local regulations relating to hazardous wastes. Therefore, implementation of GPA 15-049 had no new significant impacts or reduced impacts as compared to the Certified EIR.
Additionally, there are no public or public use airports in the general vicinity of San Clemente.
Therefore, the 2015 Addendum concluded that GPA 15-049 would not result in a safety hazard and impacts would remain less than significant.
2017 Addendum Findings: The 2017 Addendum found that adoption of the 2013-2021 Housing Element Update would not result in any new impact associated with hazardous materials, because any residential development constructed in accordance with the policies and programs of the 2013-2021 Housing Element Update would not increase the need for transport, use, or Final 43 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
disposal of hazardous materials, as these activities associated with residential development. Further, the 2013-2021 Housing Element Update did not increase the potential build-out of the City beyond that already considered and analyzed in the Certified EIR. The 2017 Addendum found no new impact would occur.
2019 Addendum Findings: Implementation of GPA 19-291 and SPA 19-292 did not change the type, scale, or intensity of development in the General Plan, except for changing two parcels on Coronado Lane from a Residential High density designation to Mixed Use. No site specific operations or development of any kind was proposed. New businesses/users would be required to follow the same regulations as existing businesses/users. The Orange County Health Care Agency Environmental Health Division implements the Hazardous Waste Inspection Program for businesses in San Clemente to ensure that all hazardous wastes generated by businesses are properly handled, recycled, treated, stored, and disposed. The General Plan also contains policies and programs to ensure compliance with federal, State, and local regulations relating to hazardous wastes. Further, future development is required to undergo a discretionary review process and CEQA review to ensure compliance with existing regulations related to hazards and hazardous materials. Thus, the 2019 Addendum found no new impacts would occur.
Proposed Project:
(a)-(d) State Water Resources Control Board and Department of Toxic Substances Control's databases identified approximately 40 potentially contaminated sites within the project area.1.2 However, no site-specific development is proposed as part of the project. The project would 1) redesignate a currently split zoned industrial property to be entirely HI, 2) expand the City's Architectural Overlay District, and 3) update the Specific Plan to be consistent with the General Plan and LUP and incorporate additional parcels within the Specific Plan area. The only proposed land use change is related to the split zoned industrial property, which would make the existing non-conforming automobile towing and salvage use on the subject property a conforming use. It should be noted that the intent of the land use change is to modify a split zoned property and convert an existing non-conforming use into a conforming use. The land use change is not anticipated to intensify use of hazardous materials associated with HI permitted uses. As such, the proposed GPA, SPA, and ZA would not result in land use changes that would increase the transport, use, or disposal of hazardous materials in the project area or near schools.
Similar to existing conditions, all future development within the expanded Specific Plan area and Architectural Overlay District would be required to comply with applicable regulations and policies related to hazards and hazardous materials. Therefore, project impacts associated with the transport, use, and disposal of hazardous materials in the City, potential release of emissions or handling of hazardous materials near schools, or being on a site identified on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5, would be less than significant. No new impacts have been identified and no new mitigation measures are required for the proposed project.
(e) As stated, there are no public or public use airports in, or in the general vicinity of San Clemente. As such, no impact in this regard would occur. 1 State Water Resources Control Board, GeoTracker, https://geotracker.waterboards.ca.gov/, accessed March 4, 2022.

(t) As discussed in Section 4.17, Transportation, the project does not propose any site-specific development that could directly impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan. The project would 1) redesignate a currently split zoned industrial property to be entirely HI, 2) expand the City's Architectural Overlay District, and 3) update the Specific Plan to be consistent with the General Plan and LUP and incorporate additional parcels within the Specific Plan area. The only proposed land use change is related to the split zoned industrial property, which would make the existing non-conforming automobile towing and salvage use on the subject property a conforming use. It should be noted that the intent of the land use change is to modify a split zoned property and convert an existing non-conforming use into a conforming use. The land use change does not include features that may impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan. Additionally, all future roadway improvements within the expanded Specific Plan area and Architectural Overlay District would be designed in accordance with the City's established roadway design standards and be subject to review by the City. Therefore, no new impacts have been identified and no new mitigation measures are required for the proposed project.

Certified EIR Findings: The Certified EIR determined that water quality exceedances are not anticipated, and pollutants are not expected in runoff that would adversely affect beneficial uses in the San Clemente Coastal Streams Watershed. Subsequently, impacts to the Water Quality Control Plan tor the San Diego Basin (Basin Plan) maintained by the San Diego Regional Water Quality Control Board (San Diego RWQCB) were determined to be less than significant. It is acknowledged that the general water quality objectives from the Basin Plan would also apply to all groundwaters of the San Diego region. During construction, applicable future development accommodated through the General Plan would be required to comply with the National Pollutant Discharge Elimination System (NPDES) General Construction Permit, including the preparation of project-specific SWPPPs and associated construction-related BMPs. During project operations, applicable future development accommodated through the General Plan would be required to incorporate site design and/or Low Impact Development (LID) features, source control and treatment control BMPs (if applicable), as well as prepare a project-specific Water Quality Management Plan (WQMP) in accordance with the current Municipal Separate Storm Sewer System (MS4) Permit, Orange County Drainage Area Management Plan (OC DAMP), and the City's Local Implementation Plan.
The Certified EIR determined that future development accommodated by the General Plan would not result in a substantial increase in the amount of impervious surfaces and would therefore not adversely impact opportunities for groundwater recharge as development would primarily occur within built out areas of the City.
The Certified EIR determined that no impacts are anticipated to downstream streams or rivers, and no increases in peak flow or volumes are expected upon implementation of the General Plan.
In addition, for those land use changes occurring in General Plan Focus Areas subject to hydromodification requirements, additional runoff controls for peak flow and volume (e.g., flow duration control) will be required to comply with the South Orange County Hydromodification Management Plan (South Orange County HMP). Implementation of hydromodification controls would act to reduce peak flows and volumes over the long term as individual projects accommodated through the General Plan are implemented.
Final 47 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
The Certified EIR determined that inundation impacts from failure of a levee or dam, seiche, mudflow, tsunami, and sea level rise would be less than significant. Further, no housing or structures are proposed with the City's 100-year flood hazard areas. Thus, the Certified EIR concluded no impact would occur in this regard.
2015 Addendum Findings: As stated, the Group C amendments under GPA 15-049 increased the allowed development density of five infill parcels that are currently developed with industria! land commercial uses. The potential changes to impervious conditions on the properties would be minimal and would not adversely impact groundwater recharge or substantially alter stormwater drainage patterns. Projects would also be subject to existing mitigation measures, programs, and best management practices to ensure compliance with water quality thresholds established in regional water quality permits. Additionally, these five parcels are not located within a 100-year flood hazard area not within the inundation area of any major dam or levee. The parcels also are all above the projected sea level rise elevation illustrated in Certified EIR Figure
5.8-5 Projected Sea Level Rise. Thus, the 2015 Addendum found no new impacts associated with hydrology and water quality would occur and no new mitigation measures were required 2017 Addendum Findings: The 2017 Addendum found that adoption of the 2013-2021 Housing Element Update would not increase impacts associated with water quality standards or waste discharge, result in new impervious surfaces, increase runoff volumes, or alter existing drainage patterns. No additional pollutant discharge resulting from implementation of any future housing projects beyond those assumed in the Certified EIR would occur. Additionally, no new development would occur that could be located in a 100-vear flood hazard area or inundation area of a major dam or levee. Thus, the 2017 Addendum found no new impacts would occur. 2019 Addendum Findings: As stated, no site specific operations or development of any kind was proposed under GPA 19-291 and SPA 19-292. Development on the two parcels is subject to a discretionary review process and CEQA review. A Water Quality Management Plan (WQMP) screening is required to ensure water quality exceedances are not anticipated and poilutants are not expected in runoff. Additionally, given that the two parcels are infill lots in the Pier Bowl Focus Area, no substantial changes are anticipated regarding groundwater recharge, impervious surfaces, and runoff volumes. Further, the two parcels are not located within a 100-year flood zone or inundation area of any major dam or levee. Thus, the 2019 Addendum found no new impacts would occur.
Proposed Project:
(a) and (e) The project would provide updates to the Specific Plan and expand the City's Architectural Overlay District. No new development would occur. While the proposed land use change on the split zoned industrial property would increase the allowable density of the property by approximately 12,180 square feet, the intent of the land use change is to make the existing non-conforming automobile towing and salvage use on the subject property a conforming use Further, similar to existing conditions, all future development within the Specific Plan area and Architectural Overlay District would be required to comply with existing local, State, and federal regulations pertaining to water quality. Thus, the proposed GPA, SPA, and ZA would not violate any water quality standards or waste discharge requirements. No new impacts have been identified and no new mitigation measures are required in this regard. (b) The project area includes the Specific Plan area and Architectural Overlay District area.

(c) As discussed above, the project would redesignate a currently split zoned industrial property, expand the existing Architectural Overlay District, and update the Specific Plan. No site-specific development is proposed. Areas of the Specific Plan and the Architectural Overlay District are also built out, and future development within these areas would be required to comply with all applicable regulations and policies detailed in Response 4.10(a) and hydromodification requirements in accordance with the South Orange County HMP, where applicable. Overall, the proposed project is not anticipated to substantially alter drainage patterns and associated impacts pertaining to erosion/siltation, flooding, runoff pollution, and impeded or redirected flood flow would be less than significant. No new impacts have been identified and no new mitigation measures are required in this regard.
(d) No new development is proposed under the project. Additionally, the Specific Plan area and Architectural Overlay District are predominantly built out and located away from flood hazard, tsunami, and seiche zones.

West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
Certified EiR Findings: The Certified EIR determined that implementation of the General Plan would not physically divide an established community as development in accordance with the General Plan would occur within existing urban areas and infill sites, and that a less than significant impact would occur in this regard.
The Certified EiR determined that the General Plan is consistent with applicable State, regional, and local laws, regulations, plans, and guidelines, including the California Government Code Section 65302, the Southern California Association of Governments' (SCAG's) 2012-2035 Regional Transportation Plan/Sustainable Communities Strategy (2012-2035 RTP/SCS), and SCAG's Compass Blueprint 2% Strategy, as one area of City is designated a Compass 2% Strategy Opportunity Area.
2015 Addendum Findings: The 2015 Addendum found that land use changes under GPA 15- 049 would not divide any established community within the City. Additionally, the Group C amendment density increases were limited to five infill parcels adjacent to mass transit and along a major road corridor. Thus, these changes were found to be consistent with the goals of the Regional Transportation Plan and Sustainable Communities Strategy. Therefore, the 2015 Addendum found GPA 15-049 would have no new or more significant impacts compared to the Certified EIR.
2017 Addendum Findings: Adoption of the 2013-2021 Housing Element Update did not increase residential development potential in the City and thus, could not result in the division of established communities. Additionally, the 2013-2021 Housing Element Update ensured that the General Plan remained consistent with State law requirements pertaining to housing provision and municipal general plans. Thus, the 2017 Addendum found no new land use impacts would occur. 2019 Addendum Findings: The land use changes under GPA 19-291 and SPA 19-292 were found to tie into the existing uses and neighborhood and not physically divide an established community. Additionally, the land use changes were found consistent with regional plans adopted to avoid or mitigate environmental effects, which tend to encourage denser development in in-fill areas closer to mass transit and major transportation corridors. Thus, the land use changes were found consistent with the goals of the Regional Transportation Plan, Sustainable Communities Strategy, and objectives of the Climate Action Plan to reduce GHG emissions in part with less vehicle miles traveled. Thus, the 2019 Addendum found no new land use impacts would occur.
Proposed Project:
(a) The project would provide updates to the Specific Plan to be consistent with the General Plan and LUP, expand the existing Architectural Overlay District to include additional parcels, and modify a currently split zoned industrial property to make an existing nonconforming automobile towing and salvage use on the subject property a conforming use. No new development is proposed as part of the project, the Specific Plan area and Architectural Overlay District area are predominantly built out, and the project does not add or reroute roadway or utility corridors. Thus, future development in these areas would not physically divide an established community.
Additionally, given the urbanized nature of the project area, no new infrastructure or improvements (e.g., roadways or utility corridors) would be constructed that could create a new barrier or obstacle for connectivity. No new impacts have been identified and no new mitigation measures are required.
(b) The project would 1) redesignate a currently split zoned industrial property to be entirely HI, 2) expand the City's Architectural Overlay District, and 3) update the Specific Plan to be consistent Final 50 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
with the General Plan and LUP pursuant to State law and incorporate additional parcels within the Specific Plan area. The project does not change the type, scale, or intensity of development contemplated in the General Plan, except for the redesignated split zoned industrial property, which would increase the maximum allowable density by approximately 12,180 square feet. The land use change would make the existing non-conforming automobile towing and salvage use on the subject property a conforming use. The Specific Plan allows two conditionally permitted uses in Hi zones that are not permitted in LI zones: 1) towing and salvage yards, and 2) concrete batch plants, though the project would preclude concrete batch plans on the subject property. It should be noted that the intent of the land use change is to modify a split zoned property and convert an existing non-conforming use into a conforming use. The land use change is not anticipated to intensify existing heavy industrial uses and is intended to 'clean up' the split zoned property. The Specific Plan area is also an older industrial area of the City and thus, the land use change would be consistent with the General Plan and other applicable land use plans.
The project also proposes to expand the current Architectural Overlay District to include several properties that front primary circulation routes between the Downtown and Pier Bowl, in order to integrate the architectural character of the visitor-serving districts. Existing land use designations and zoning underlying the overlay district would remain the same. As such, a GPA and ZA are proposed to reflect the expanded Architectural Overlay District on applicable General Plan and zoning maps to include these newly added properties. Upon approval of the requested GPA and ZA, future development in these visitor-serving areas would be required to comply with the architectural design guidelines under the overlay district and further establish the City's traditional Spanish and Spanish Colonial Revival architectural style and pedestrian orientation in the district.
The project would also update the Specific Plan to be consistent with the General Plan and LUP.
The project proposes to update the development standards, permitted uses, design guidelines, and other content within the Specific Plan to be consistent with the General Plan and LUP, as required by State law. As such, the Specific Plan updates would make future development within the area more consistent with the General Plan and LUP compared to existing conditions.
Additionally, the project proposes to expand the Specific Plan area to include the entirety of the General Plan Los Molinos Focus Area. By incorporating the entirety of the focus area, the Specific Plan would become a more useful and effective tool to implement General Plan goals and policies with updated development standards and design guidelines. It is also acknowledged that four additional parcels are proposed to be included in the Specific Plan area. Currently, these four parcels are zoned LI and the parcels on Calle Lago and North El Camino Real are also in the Mixed-Use (MU) Overlay District, where mixed use developments are allowed pursuant to Mixed Use 1 (MU) zoning standards. Upon approval of the SPA and ZA, the Specific Plan's LI development standards and permitted uses would be applied to the additional parcels, consistent with the parcels' existing zoning.
Overall, upon approval of the requested entitlements, the project would be consistent with applicable land use plans and zoning, including the General Plan, LUP, and Municipal Code "hus, no new impacts have been identified and no new mitigation measures are reauired in thi regard.

West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
Mitigation Measure 10-1, long-term noise impacts on new land uses from transportation sources would be reduced to less than significant. Upon implementation of Mitigation Measure 10-5, long- term train-related and industrial-related vibration impacts would be reduced to be less than significant. However, even with the implementation of Mitigation Measures 10-1 through 10-5, long-term noise impacts on existing sensitive uses from transportation sources, short-term construction noise impacts, and short-term construction vibration impacts would remain significant and unavoidable.
Additionally, there are no public or public use airports in or in the general vicinity of San Clemente.
Thus, the Certified EIR found impacts in this regard to be less than significant. 2015 Addendum Findings: The 2015 Addendum found that implementation of GPA 15-049 reduced potential traffic related impacts by more than 13,000 average daily trips with a corresponding decrease in air emissions, greenhouse gas emissions, and roadway noise impacts.
This is due to the fact that GPA 15-049 reduced development intensity of General Plan build-out.
Overali, Group B amendments reduced development and more than offset density increases from Group C amendments, resulting in less development over the build-out period. Therefore, the 2015 Addendum found implementation of GPA 15-049 would result in no new impacts or would reduce impacts as compared to General Plan build-out.
2017 Addendum Findings: The 2017 Addendum concluded that adoption of the 2013-2021 Housing Element Update would not result in additional noise impacts or additional potential for uses to be subjected to noise above 65 dBA. Although future housing projects may be constructed pursuant to the 2013-2021 Housing Element Update, such projects could also occur without the Housing Element Update and under the General Plan. The 2013-2021 Housing Element Update policies and programs did not increase the potential for more short- or long-term noise or vibration impacts than was already considered. Mitigation measures required under the Certified EIR would remain in effect and apply to any new development.
2019 Addendum Findings: Implementation of GPA 19-291 and SPA 19-292 did not change the type, scale, or intensity of development in the General Plan, except for changing two parcels on Coronado Lane from a Residential High density designation to Mixed Use. The land use change allowed 16,340 square feet of commercial uses on the two parcels, where the prior land use designation allowed residential uses only. The change did not allow new noise-sensitive land uses in areas where the ambient noise level clearly exceeds compatible levels for that use. Instead, GPA 19-291 and SPA 19-292 allowed new commercial uses in a mixed use area with a higher tolerance for exterior noise levels.
The land use change added approximately 240 potential net new daily traffic trips that would generate roadway noise. However, several land use changes were adopted in 2015 (i.e., GPA 15-049) that reduced the General Plan build-out, which more than offset noise impacts associated with GPA 19-291 and SPA 19-292. As a result, the 2019 Addendum found no new impacts would occur and prior mitigation measures remained applicable.
Proposed Project:
(a)-(b) The proposed project would update the Specific Plan to be consistent with the General Plan and LUP and expand the Specific Plan area to include the entirety of the General Plan Los Molinos Focus Area; redesignate the two split zoned parcels at 1510 Avenida De La Estrella from HI and LI to be entirely HI; and expand the City's existing Architectural Overlay District to include several properties that front primary circulation routes between the Downtown and Pier Bowl. The Final 54 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
expansions of the Specific Plan area and Architectural Overlay District would not affect noise impacts, as the expansions would not change the existing land use and zoning designations of the areas, and thus would not change the short-term construction or long-term operational activities and associated noise levels.
The proposed redesignation of the two parcels at 1510 Avenida De La Estrella would increase the maximum allowed density from a 0.50 FAR to 0.75 FAR, and make the existing non- conforming automobile towing and salvage use on the subject parcels a conforming use. The redesignated parcels are located approximately 100 feet to the north of the closest single-family residential uses, and could potentially result in long-term noise and vibration impacts from industrial-related stationary sources. However, the conforming automobile towing and salvage use on the redesignated parcels would not generate higher noise and vibration levels than what was analyzed in the Certified EIR, and upon implementation of regulatory requirements, General Plan policies, and Mitigation Measure 10-5, impacts would remain less than significant. According to the U.S. Department of Transportation Federal Highway Administration's Techniques for Reviewing Noise Analyses and Associated Noise Reports, a doubling of traffic volumes would result in a 3 dB increase in traffic noise levels, which is barely detectable by the human ear. As detailed in the Transportation Analysis, the proposed land use change would result in approximately 80 net new average daily trips over the existing 175 trips. Thus, the generated daily trips would not double existing traffic volumes and any increase in traffic noise levels would be imperceptible. Overall, the proposed redesignation of the two parcels would not affect short-term construction noise and vibration impacts, or long-term noise and vibration impacts from transportation and rail sources, as the redesignation would not change the level of construction activities or doubling trips or VMT compared to existing conditions. As such, no new construction and operational noise and vibration impacts are identified, and no new mitigation measures are required.
(C) There are no public or public use airports in or in the general vicinity of San Clemente. Thus, the proposed project would not expose people residing or working in the project area to excessive airport noise levels, and no new impacts are identified.

No new mitigation measures are required.

Certified EIR Findings: The Certified EIR determined that while build-out in accordance with the General Plan would increase both population and employment in the City, impacts in this regard would be less than significant because the General Plan would improve the job-housing balance and is consistent with regional policies.
2015 Addendum Findings: The 2015 Addendum found that the Group B amendments reduced development and more than offset density increases from Group C amendments, resulting in less development over the General Plan build-out period. Therefore, GPA 15-049 was expected to maintain or reduce population growth identified in the Certified EIR. Additionally, GPA 15-049 did not change land use designations or standards in such a way that eliminated substantial numbers of existing housing units or displaced substantial numbers of peoples. The 2015 Addendum found no new or more significant impacts would result from implementation of GPA 15-049. 2017 Addendum Findings: Adoption of the 2013-2021 Housing Element Update did not result in new or increased population growth impacts because no new development would occur beyond what was previously contemplated in the Certified EIR. As such, the 2017 Addendum found no new population and housing impacts would occur.
2019 Addendum Findings: The land use changes allowed 16,340 square feet of commercial use on two parcels where the prior land use designation allowed residential uses only. The addition of commercial space is expected to increase employment opportunities in the Pier Bowl Focus Area that may improve the jobs housing balance for residents in the vicinity. Future employment growth associated with the land use changes were previously analyzed in the Certified EIR. Additionally, in 2015, several land use changes were adopted that reduced the General Plan build-out to an extent than more than offset growth inducing impacts associated with GPA 19-291 and SPA 19-292. Further, no site specific operations or development of any kind was proposed. Development on the parcels is subject to a discretionary review process and CEQA review. Thus, the 2019 Addendum found no new impacts would occur.
Proposed Project:
(a)-(b) The project would not directly result in population growth or displace people or housing as no site-specific development would occur. The one proposed land use change for the split zoned industrial property at 1510 Avenida De La Estrella would increase the maximum allowed density of the property by approximately 12,180 square feet. This nominal increase in development potential for one property would not result in a significant increase in population or employment growth in the City beyond what was analyzed in the Certified EIR. Additionally, it is acknowledged that the intent of the land use change is to make the existing non-conforming automobile towing Final 56 May 2022

and salvage use on the subject property a conforming use. Thus, no new impacts have been identified and no new mitigation measures are required.

Certified EIR Findings: According to the Certified EIR, build-out of the General Plan could result in an increased number of persons and businesses within the City. Accordingly, the build-out of the General Plan could result in an increase in the need for fire, police, school, parks and recreation, and other public services (i.e., library services). The Certified EIR concluded that upon implementation of the General Plan and compliance with applicable General Plan policies related to public services, impacts in this regard would be less than significant. Additionally, pursuant to Senate Bill (SB) 50, payment of development impact fees would provide funding for the financing Final 57 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
of school facilities. Additional City tax revenues generated from new dwelling units and businesses would contribute toward the City's General Fund, which would fund fire, police, and library services.
2015 Addendum Findings: GPA 15-049 reduced development intensity by up to 1,686,000 commercial square feet and 10 dwelling units. Thus, the 2015 Addendum found that the overall demand for public services was not expected to change significantly or may be reduced on a City- wide basis with implementation of GPA 15-049 compared to projected demands analyzed in the Certified EIR. The 2015 Addendum found no new or more significant impacts would occur. 2017 Addendum Findings: Adoption of the 2013-2021 Housing Element Update did not increase potential impacts to public services because it did not accommodate growth beyond what was previously analyzed in the Certified EIR, and the City's policies for ensuring adequate public service levels would remain in place. The 2017 Addendum found no new impact would occur. 2019 Addendum Findings: As stated, the approved land use change allowed 16,340 square feet of commercial uses on two parcels, where the prior land use designation allowed residential uses only. The addition of commercial uses on the parcels is within the scope of impacts identified and mitigated in the Certified EIR. In 2015, several land use changes were adopted that reduced the General Plan build-out to an extent that more than offset growth inducing impacts associated with GPA 19-291 and SPA 19-292. Additionally, no site specific operations or development of any kind was proposed. Development on the parcels is subject to a discretionary review process and review under CEQA. Thus, the 2019 Addendum found no new impacts associated with public services would occur.
Proposed Project:
(a) The proposed project would expand the Specific Plan area and provide updates to the Specific Plan to be consistent with the General Plan and LUP, and expand the existing Architectural Overlay District to include additional parcels. The project would not result in changes to the type, scale, or intensity of development contemplated in the General Plan and previously analyzed in the Certified EIR, with the exception of an existing split zoned industrial property at 1510 Avenida De La Estrella within the Specific Plan area. The project proposes to redesignate the property from HI and LI to entirely Hi, which would increase the property's maximum allowed density by approximately 12,180 square feet. However, it should be noted that the intent of the land use change is to modify a split zoned property and convert an existing non-conforming use into a conforming use. The Specific Plan area is largely built out and the proposed industrial land use change would not result in a substantial increase in residents or jobs. Further, future development of the subject property would be required to undergo separate environmental review under CEQA.
Additionally, payment of development impact fees pursuant to SB 50 would also offset impacts on school services. Thus, the proposed project itself would not result in any additional impacts to public services, including fire, police, park, school, and library services. As such, no new impacts are identified, and no new mitigation measures are required.

Certified EIR Findings: According to the Certified EIR, build-out of the General Plan could generate additional residents in the City, and could therefore increase the demand for parks and existing park usage. However, future development pursuant to the General Plan could also result in the construction of new or expansion of existing recreational facilities in the City. General Plan Policy LU-1.04 requires residential developments be designed to promote feasible access to the City's amenities, including community facilities, parks, open spaces, and trails. General Plan Policy LU-6.01 requires the continuation of Public and Institutional land uses (i.e., public recreational facilities) in their respective land use areas and zones. Additionally, under the Quimby Act, and pursuant to Municipal Code Article 70, Park and Recreational Facilities, future development would also be required to pay in-lieu fees to offset impacts on the City's parks and recreational services.
The Certified EIR found that adherence to these regulations would reduce impacts to parks and recreational facilities to less than significant levels. 2015 Addendum Findings: GPA 15-049 reduced allowed development density of General Plan build-out up to 1,686,000 commercial square feet and 10 dwelling units. Therefore, the 2015 Addendum found that the overall demand for recreational facilities was not expected to change significantly or may be reduced compared to General Plan built-out. 2017 Addendum Findings: The 2017 Addendum found that adoption of the 2013-2021 Housing Element Update did not increase potential impacts to recreational services because it did not accommodate growth beyond what was previously analyzed in the Certified EIR, and the City's policies for ensuring adequate recreational service levels would remain in place. The 2017 Addendum found no new impact would occur.
2019 Addendum Findings: As stated, the land use change on the two parcels allowed 16,340 square feet of commercial uses. Implementation of GPA 19-291 and SPA 19-292 was not expected to induce population growth given the land use change was limited to allowing commercial uses in a mixed use area, where the prior land use designation allowed residential uses only. The addition of commercial uses on the subject parcels was within the scope of impacts Final 59

identified and mitigated in the Certified EIR. Additionally, in 2015, several land use changes were adopted that reduced the General Plan build-out to an extent that more than offset growth inducing impacts associated with GPA 19-291 and SPA 19-292. No site specific operations or development of any kind was proposed and future development on the parcels is subject to a discretionary review process and CEQA review. Thus, the 2019 Addendum found no new impacts would occur.
Proposed Project:
(a)-(b) The proposed project does not invoive any land use changes that would increase the City's residential population. The intent of the one proposed land use change for the split zoned industrial property is to modify the split zone and convert an existing non-conforming automobile towing and salvage use on the subject property a conforming use. Thus, the project would not induce substantial population growth that would increase the use of the City's parks and recreational facilities. Further, future development would be required to pay in-lieu fees to offset impacts on the City's parks and recreational facilities pursuant to Municipal Code Article 70, Park and Recreational Facilities. Therefore, no new impacts are identified, and no new mitigation measures are required.

Certified EIR Findings: The Certified EIR determined that no conflict with policies, plans, and programs for alternative transportation would occur from future development and redevelopment under the General Plan. Implementation of the General Plan would promote the use of alternative transportation modes and several policies included in the General Plan would promote the development of new or expanded transportation facilities. Specifically, General Plan Policy M-1.12, Design Integration, would ensure that development projects and subdivisions are designed and/or retrofitted to incorporate, and be efficiently served by, public transit, pedestrian and bicycle facilities.
General Plan Policy M-1.19, Street Redesign, promotes the consideration multimodal alternative improvements to nonautomotive facilities during street redesign projects. Additionally, General Plan Policies M-2.01 to M-2.36 promote the use of alternative modes of transportation and to assist on the implementation of the City's Bicycle and Pedestrian Master Plan.
The Certified EIR concluded that the General Plan build-out would generate vehicle trips in a manner that would impact levels of service (LOS) for the existing area roadway system. The Certified EIR determined that, without mitigation, implementation of the General Plan Land Use Plan and Mobility and Complete Streets Element would cause several roadway segments and intersections to operate at unacceptable LOS, resulting in significant traffic impacts. As a result, the Certified EIR identified Mitigation Measures 14-1 and 14-2, which identify intersection and roadway segment improvements that would improve LOS at impacted locations. However, the Certified EIR also determined that right-of-way acquisitions would be required to implement some of these improvements, and acquisition is not guaranteed. Therefore, impacts were determined to be significant and unavoidable in this regard.
Final 61 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
The Certified EIR determined that while build-out of the General Plan would result in some changes to the City's circulation network, it would not increase hazards or impact emergency access due to design features with implementation of General Plan Policies M-3.01 to M-3.06, and impacts would be less than significant in this regard. General Plan Policies M3.01 to M-3.06 would encourage multimodal transportation and protect travelers' safety. All future roadway system improvements associated with development and redevelopment activities under the General Plan would be designed in accordance with the established roadway design standards and be subject to review and future consideration by the City, which would include an evaluation of roadway alignments, intersection geometrics, and traffic control features. 2015 Addendum Findings: GPA 15-049 reduced potential traffic related impacts disclosed in the Certified EIR by more than 13,000 daily trips. This is because General Plan Amendment 15- 049 reduced allowed development density of General Plan build-out up to 1,686,000 commercial square feet and 10 dwelling units. Group A amendments had no potential to impact the environment. These items are limited to correcting maps and text to reflect EIR analysis and policy intent. Several Group B amendments collectively reduced build-out of commercial square footage up to 1,898,000 square feet and 64 housing units, which eliminated over 15,000 daily traffic trips.
There are only four Group C amendments that increased allowed development density of five parcels. In total, Group C amendments added up to 212,000 square feet of commercial uses and 54 housing units, which added up to approximately 1,560 trips per day and was determined to not likely change the LOS at nearby critical intersections such as El Camino Real and Avenida Pico from the prior projected LOS D. Overall, Group B amendments reduced development and more than offset density increases from Group C amendments. This resulted in less development over the General Plan build-out period and a reduction in daily traffic trips which can improve the performance of the circulation over the build-out period. Therefore, the 2015 Addendum found GPA 15-049 had no new impacts or would reduce impacts compared to the Certified EIR. 2017 Addendum Findings: The 2017 Addendum found that adoption of the 2013-2021 Housing Element Update would not result in additional increases in impacts at intersections and segments beyond the impacts already identified and disclosed in the Certified EIR. The 2017 Addendum found no new impacts would occur.
2019 Addendum Findings: The 2019 Addendum found that implementation of GPA 19-291 and SPA 19-292 did not change the type, scale, or intensity of development in the General Plan, except for changing two parcels in the Pier Bowl area on Coronado Lane from a Residential High density designation to Mixed Use. The land use change was limited to allowing 16,340 square feet of commercial uses in a mixed use area, where the prior land use designation allowed residential uses only. This growth in commercial build-out added approximately 240 potential net new daily traffic trips, which was not anticipated to change the traffic model peak hour LOS at the nearby study intersections on El Camino Real. The peak hour trips were comprised of a percentage of the daily trips and were considered low. Once these peak hour trips were dispersed directionally within the street system in the study area, the net trip numbers were determined to be negligible and would not have a discernable effect on traffic operations and flow. Additionally, several land use changes adopted in 2015 reduced the General Plan build-out and this reduction of development potential would reduce traffic and congestion on the roadway network. In conclusion, the 2019 Addendum found GPA 19-291 and SPA 19-292 would have no new impact.
Proposed Project:
(a) The project would provide updates to the Specific Plan to be consistent with the General Plan and LUP, and expand the existing Architectural Overlay District to include additional parcels.
Final 62 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
Additionally, a split zoned industrial property at 1510 Avenida De La Estrella would be redesignated from HI and LI to be entirely HI, and the property's maximum allowed density would increase by approximately 12,180 square feet. This land use intensity increase for one property is not anticipated to significantly impact the City's circulation system, including transit, roadway, bicycle and pedestrian facilities beyond what was analyzed in the Certified EIR. Additionally, it is acknowledged that the intent of the land use change is to modify a split zoned property and convert an existing non-conforming use into a conforming use. Thus, no new impacts have been identified and no new mitigation measures are required. (b) The Certified EIR did not evaluate VT impacts as it was not required in the CEQA Guidelines at the time the Certified EIR was prepared in 2013. Therefore, the proposed project's impacts, as currently proposed, is discussed below.
Michael Baker International prepared the West Pico Corridor Specific Plan Update and General of Orange's 2020 Updated Transportation Implementation Manual (TIM), amended November 17, 2020, was utilized as a resource for the VMT assessment as the City has not yet adopted its own transportation impact study guidelines. According to the TIM, a project is presumed to have a less than significant VMT impact and would be exempt from project-level VMT assessment based on the following screening criteria:
• Project in High-Quality Transit Area (HQTA);
• Neighborhood Retail Project;
• Affordable Housing;
• Low VMT Area Project;
• Small Project; and
• Public Facilities.
The Transportation Analysis determined that the project would meet two of the County's VMT Analysis concluded that less than significant VMT impacts would occur and a full VMT assessment is not required. As such, the project would not conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b). No new impacts have been identified and no new mitigation measures are required.
Consistent with effective CEQA Appendix G checklist questions when the EIR was prepared, intersection operations analysis was also conducted in the Transportation Analysis to determine potential LOS changes upon implementation of the proposed project. The proposed project is anticipated to generate 80 net new trips, including 10 a.m. peak hour trips and 15 p.m. peak hour trips; refer to Transportation Analysis Table 3, General Plan Amendment Trip Generation Summary. It should be noted that the subject property is fully developed and the proposed land use change would not affect the existing trips generated by the site. Trips from the developed site are already considered in the existing traffic counts, therefore, the analysis focuses on the net change in potential trips as a result of the land use change to modify the split-zoned property. An intersection operational analysis was conducted at two intersections near the project site to determine if the additional traffic would negatively affect intersection operations. The two intersections evaluated in the Transportation Analysis were:
Finai 63 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
1. Calle De Los Molinos & Avenida Pico (Signalized); and
2. Calle De Los Molinos & Avenida De La Estrella (All-Way Stop Control) To determine the existing operations at the two study intersections, a.m. and p.m. peak hour intersection turning movement counts were collected on Wednesday, February 9, 2022. Morning peak period counts were collected from 7:00 to 9:00 a.m. and evening peak period counts were collected trom 4:00 to 6:00 p.m. The counts used in this analysis were taken from the highest hour within the peak periods. Pedestrian and bicycle counts were also collected at each intersection during the a.m. and p.m. peak periods.
Existing Conditions
Transportation Analysis Table 5, Existing Intersection Level of Service Comparison, shows the LOS results for the 2010 Base Year Condition from the Certified EIR and Existing Conditions (Year 2022). As shown, both intersections currently operate at LOS A, which is considered acceptable operating conditions in the County and City. The net increase in traffic associated with the proposed land use change was assumed to have a similar distribution and travel pattern as trip characteristics of the existing use on-site. Traffic volumes from the proposed land use change were added to existing traffic volumes to determine potential changes in LOS at the two study intersections. As shown in Transportation Analysis Table 6, Existing & Existing Plus General Plan Amendment Intersection Level of Service Summary, both intersections are forecast to operate at LOS A with the addition of project-generated traffic. As such, intersection improvements are not required
Future Condition (Year 2035)
The Certified EIR evaluated a Future Condition scenario assuming a buildout year of 2035. Within the Future Condition analysis, the Certified EIR analyzed a Preferred General Plan scenario which allowed for greater density development ranging from office to mixed-use development throughout the focus areas of the City. The Preferred General Plan scenario included an alternative with the completion of the Foothill Transportation Corridor (FTC). The FTC is the extension of State Route 241 from Oso Parkway to Cow Camp Road, which was completed in 2019. Therefore, the Future Condition (Year 2035) scenario in this analysis is based on the Preferred General Plan With FTC scenario.
According to the Certified EIR, the Calle De Los Molinos & Avenida Pico intersection was forecast to operate at LOS F during the PM peak hour under Future Condition (Year 2035). The City considers LOS E or F unacceptable intersection operating conditions. Therefore, the Certified EIR included mitigation at this intersection to improve operating conditions to LOS D or better.
Recommended improvements included restriping the Calle De Los Molinos northbound approach to have one shared through-left turn and one right-turn lane with signal modifications. This restriping improvement has already been implemented at the intersection and therefore is included in the Future Condition (Year 2035) analysis.
It is noted that the Certified EIR did not evaluate the intersection of Calle De Los Molinos & Avenida De La Estrella. Therefore, the Transportation Analysis developed AM and PM peak hour traffic volumes by assuming the same growth from existing conditions (Year 2022) to Future Condition (Year 2035) at the Calle De Los Molinos & Avenida Pico intersection.
As shown in Transportation Analysis Table 7, Future Conditions (Year 2035) & Future Conditions (Year 2035) Plus General Plan Amendment (GPA) Intersection Level of Service Summary, both Final 64 May 2022
rest Pico Corridor Specitic Plan Update and Architectural Overlay Expansio centennial General Plan EiR Addendum No.
intersections are forecast to operate at acceptable levels of service in the Future Condition (Year 2035) and Future Condition (Year 2035) Plus General Plan Amendment scenarios. Therefore, no further improvements are required at this location.
(c)-(d) The project does not propose any site-specific development. All future roadway improvements within the expanded Specific Plan area and Architectural Overlay District would be designed in accordance with the City's established roadway design standards and be subject to review by the City. Future improvements would also be required to comply with General Plan Policies M-3.01 to N-3.06, which encourage multimodal transportation and traveler safety.
Therefore, no new impacts have been identified and no new mitigation measures are required for the proposed project.

Certified EIR Findings: The Certified EIR did not evaluate impacts on tribal cultural resources as it was not required in the CEQA Guidelines at the time the Certified EIR was prepared in 2013. 2015 Addendum Findings: The 2015 Addendum did not evaluate impacts on tribal cultural resources as it was not required in the CEQA Guidelines at the time the 2015 Addendum was prepared in 2015.
2017 Addendum Findings: The 2017 Addendum found that adoption of the 2013-2021 Housing Element Update did not result in additional impacts beyond those already identified in the Certified EIR. These actions did not result in new areas of disturbance or an increased amount of disturbance over what was originally analyzed, and the regulations, policies, and mitigation measures identified in the General Plan EIR continue to apply. The 2017 Addendum found no new impacts would occur. 2019 Addendum Findings: The 2019 Addendum did not evaluate impacts on tribal cultural resources.
Proposed Project:
(a) As stated, the Certified EIR did not evaluate impacts on tribal cultural resources as it was not required in the CEQA Guidelines at the time the Certified EIR was prepared in 2013. Therefore, the proposed project's impacts, as currently proposed, is discussed below.
The proposed project would provide updates to the Specific Plan to be consistent with the General Plan and LUP, and expand the existing Architectural Overlay District to include additional parcels The project would not change the type, scale, or intensity of development in the General Pian, with the exception of modifying a split zoned industrial property located at 1510 Avenida De La Estreila from HI and Li to entirely Hi. The project would not directly result in construction or grading activities that could impact tribal cultural resources, as no site-specific development would occur.
Future development on the subject property would be required to undergo separate environmental review under CEQA, that would include applicable tribal consultation regarding tribal resources as required under Assembly Bill 52 (AB 52). As such, the proposed modifications would not result in any adverse impacts to tribal cultural resources. impacts would be less than significant and no new mitigation measures are required.

Certified EIR Findings: The Certified EIR determined that implementation of the General Plan would result in less than significant impacts pertaining to water, wastewater treatment, stormwater drainage, electric power, natural gas, and telecommunications facilities. Future development projects would also be required to prepare a site-specific Water Supply Assessment (WSA), SWPPP, or sewer capacity study as part of the approval process through the City, where applicable, and be subject to existing federal, State, and local regulations. 2015 Addendum Findings: As stated, Group B amendments under GPA 15-049 reduced development potential and more than offset density increases from Group C amendments, resulting in less development over the General Plan build-out period. Thus, GPA 15-049 would have similar or less demand and impacts on utilities and service systems, including water, wastewater, stormwater drainage, and solid waste. As a result, implementation of GPA 15-049 would have no new impacts or would reduce impacts as compared to the Certified EIR. 2017 Addendum Findings: The 2017 Addendum found that adoption of the 2013-2021 Housing Element Update did not increase the permitted development potential within the City. Therefore, the 2013-2021 Housing Element Update did not increase demand or impacts on utilities and service systems, including water, wastewater, stormwater drainage, and solid waste. The 2017 Addendum found no new impacts would occur.
2019 Addendum Findings: The 2019 Addendum concluded that implementation of GPA 19-291 and SPA 19-292 allowed 16,340 square feet of commercial uses on two parcels. GPA 19-291 and SPA 19-292 did not induce population growth given the land use change was limited to allowing commercial uses in a mixed use area, where the prior land use designation allowed residential uses only. The addition of commercial uses on the parcels was within the scope of impacts identified and mitigated in the EIR. In 2015, several land use changes were adopted that reduced the General Plan build-out to an extent that more than offset growth inducing impacts associated with GPA 19-291 and SPA 19-292. No site specific operations or development of any kind was proposed and future development on the parcels is subject to a discretionary review process and CEQA review, in which required infrastructure, including water, wastewater, stormwater drainage, and solid waste facilities and services would be evaluated and necessary improvements would be required to allow future development. Thus, no new impacts would occur.
Proposed Project:
(a)-(e) As discussed in Section 4.14, Population and Housing, the project would not involve site- specific development; thus, the proposed project would not directly result in population growth that could increase demand on utilities and service systems. While the project would redesignate a currently split zoned industrial property from HI and LI to be entirely HI and result in an allowable density increase of approximately 12,180 square feet, this nominal increase in land use intensity is not anticipated to significantly increase demand for water, wastewater treatment, stormwater drainage, electric power, natural gas, telecommunications facilities, or solid waste facilities Finai 68 May 2022

beyond what was analyzed in the Certified EIR. Therefore, no new impacts have been identified and no new mitigation measures are required for the proposed project.

The Specific Plan and Architectural Overlay District are located in predominantly built out and urbanized areas of the City. According to the California Department of Forestry and Fire Protection's Orange County Fire Hazard Severity Zones in LRA Map, the project site is not located within a State Responsibility Area (SRA) nor is it located in a Very High Fire Hazard Severity Zone. Additionally, Figure 5.7-1, Wildfire Hazard Zones, of the Certified EIR shows that the project site is not located within a Very High Fire Hazard Severity Zone. Accordingly, no impacts would accur in this regard.
Mitigation Measures
No new mitigation measures are required.

areas, are built out and urbanized, and lack natural habitats for biological resources. The project would not change the type, scale, or intensity of development previously contemplated in the General Plan and analyzed in the Certified EIR, with the exception of modifying the split zoned industrial property at 1510 Avenida De La Estrella. However, this land use change is not expected to result in any impacts to existing biological, cultural, or paleontological resources. Similar to existing conditions, future development in the Specific Plan area and Architectural Overlay District would be required to comply with existing local, State, and federal regulations and applicable mitigation measures outlined in the Certified EIR. As such, the project would not 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, substantially 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 new impacts are identified, and no new mitigation measures are required. (b) As analyzed above, the project would not have new impacts or substantially increase impacts, and previous mitigation measures from the Certified EIR remain feasible to minimize impacts. The Certified EIR found that General Plan build-out would have less than significant impacts to all environmental topical areas except for air quality, noise, greenhouse gas emissions, and traffic. The proposed project is consistent with the previous analyses. The proposed project would update the Specific Plan to be consistent with the General Plan and LUP, and expand the existing Architectural Overlay District to include additional parcels. The project would not change the type, scale, or intensity of development in the General Plan, with the exception of changing the land use designation of one property located at 1510 Avenida De La Estrella (APNs 057-020-45 and 057- 020-67) from a split land use designation of HI and LI to entirely HIl. While the land use change would increase the property's maximum allowable density by approximately 12,180 square feet, the intent of the land use change is to modify the split zoned property and convert the existing non- conforming automobile towing and salvage use on the subject property to a conforming use. Thus, the project would not introduce any new cumulative impacts not previously identified in the Certified EIR. No new impacts are identified, and no new mitigation measures are required. (c) As analyzed in response to 4.21(a) and 4.21(b), the project would not result in any new impacts or substantially increase impacts. Previous mitigation measures identified in the Certified EIR remain feasible to minimize project impacts.

5.0 DETERMINATION/ADDENDUM CONCLUSION
The City conducted an environmental review in conformance with CEQA and the State CEQA Guidelines and determined the project does not cause new significant environmental effects or substantially increase environmental effects previously studied and mitigated within the Certified ER. Therefore, an addendum may be prepared, pursuant to CEQA Guidelines Section 15164(b), as minor technical changes or additions to be made to the EIR to reflect the project. Addendum No. 4 has been prepared per Public Resources Code Section 21166 and State CEQA Guidelines Sections 15162 and 15164, based on the following conclusions.
5.1 NO MAJOR EIR REVISIONS REQUIRED DUE TO ENVIRONMENTAL
EFFECTS
There are no substantial changes proposed in the project which would require major revisions of the Certified EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects, in that:
1. The Initial Study for the Certified EIR found the implementation of the General Plan will not result in impacts to Agricultural and Forestry Resources and Mineral Resources, so no additional discussion of these two impact categories or mitigation was necessary in the Certified EIR. The project does not change these previous conclusions. The project does not create new significant environmental effects to these categories or change the circumstances in which the Initial Study was completed to require major revisions to previous analysis. The City continues to have no farmland or known mineral resource areas.
2. The project does not create new significant environmental effects or substantially increase environmental effects found to be less than significant or less than significant with mitigation in the EIR with mitigation: Aesthetics, Biological Resources, Cultural Resources, Geology and Soils, Hazards and Hazardous Materials, Hydrology and Water Quality, Land Use and Planning, Population and Housing, Public Services, Recreation, and Utilities and Service Systems. The project does not significantly change the circumstances and assumptions in which the Certified EIR was completed and the project is consistent with the environmental impact analysis, findings, and mitigation in the Certified EIR; as described in Section 4.0, Environmental Assessment.
3. The project does not increase the severity of significant unavoidable impacts identified in the Certified EIR, which were Air Quality, Greenhouse Gas Emissions, Noise, and Transportation/Traffic; in that:
a. The project proposes to modify two split-zoned industrial parcels located at 1510 Avenida De La Estrella (APNs 057-020-45 and 057-020-67) within the current Specific Plan area. The two parcels would be redesignated from HI and Ll to be entirely HI. The redesignation would increase the maximum allowed density from a 0.50 FAR to 0.75 FAR, resulting in an allowable density increase from approximately 87,235 square feet to 99,415 square feet (net increase of 12,180 square feet). Additionally, the land use change would make the existing non- Final 72 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
conforming automobile towing and salvage use on the subject parcels a conforming use. The land use change would add approximately 80 net new average daily trips. This additional growth would generate emissions and roadway noise. However, the project is within the scope of impacts identified and mitigated in the Certified EIR.
In 2015, the City adopted GPA 15-049 that reduced the General Plan build-out up to 1,686,600 commercial square feet and 10 dwelling units. This reduced development-related impacts, including traffic, air quality, greenhouse gas emissions, and noise impacts. The amended build-out projections reduced traffic by more than 12,629 daily trips and decreased air emissions to an extent that more than offsets impacts from the project. Additionally, in 2019, the City adopted GPA 19-291 that allowed an additional 16,340 square feet of commercial use and approximately 240 net new daily traffic trips and corresponding emissions and roadway noise to the impacts analyzed in the EIR for General Plan build-out.
However, these potential impacts were found to be offset by the land use changes the City adopted in 2015 with GPA 15-049 and the 2015 Addendum. Considering the prior build-out reductions and proposed land use change under GPA 15-049, the City found GPA 19-291 reduces the General Plan build-out in the EIR by 1,670,260 commercial square feet and reduces daily traffic trips by 12,389 Therefore, GPA 19-291 shifted impacts from some parcels to other parcels and the overall reduction of development potential in the General Plan more than offset project-level impacts.
For the proposed GPA 21-238, the land use change at 1510 Avenida De La Estrella would result in approximately 80 net new average daily trips and associated emissions and roadway noise. Given the nominal increase in traffic trips under the proposed project and prior build-out reductions under GPA 15-049, the project would not increase the overall development potential originally considered and analyzed in the Certified EIR. Therefore, the project does not increase impacts previously found to be significant and unavoidable, and prior mitigation measures remain feasible to minimize impacts. b. The project expands the current Architectural Overlay District to include several properties that front primary circulation routes between the Downtown and Pier Bowl in order to integrate the architectural character of the visitor-serving districts.
Existing land use designations and zoning underlying the overlay district would remain the same. Therefore, this portion of the project does not change the circumstances and assumptions in which the Certified EIR was completed. These amendments are consistent with the environmental impact analysis, findings, and mitigation in the Certified EIR.
c. The proposed Specific Plan amendments are necessary to make development standards, land uses classifications, design guidelines, and procedures in the West Pico Corridor Specific Plan consistent and compatible with goals, policies, land uses, and standards in the City's General Plan and LUP; pursuant to California Government: Code Section 65300.5. Therefore, the project updates the Specific Plan to be consistent with the environmental analysis and mitigation in the Certified EIR.
Final 73 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
d. The project proposes to expand the current Specific Plan area to include the entirety of the General Plan Los Molinos Focus Area. By incorporating the entirety of the focus area, the Specific Plan would become a more useful and effective tool to implement General Plan goals and policies with updated development standards and design guidelines. Four additional parcels at 1511 Avenida De La Estrella, 108 and 1607 Calle Lago, and 1623 North El Camino Real are also proposed to be included in the Specific Plan area, and would maintain their existing LI zoning Overall, the parcels proposed to be incorporated into the Specific Plan area would maintain their existing land use designations and zoning. Therefore, this portion of the project does not change the circumstances and assumptions in which the Certified EIR was completed. These amendments are consistent with the environmental impact analysis, findings, and mitigation in the Certified EIR. e. The type and extent of construction activities and the operational characteristics of the General Plan as amended would not differ substantially from what was previously evaluated in the Certified EIR. Therefore, the project would not change the analysis or conclusions regarding cumulative impacts, and the finding of less than significant cumulative impacts made in the Certified EIR would also apply to this Addendum.
5.2 NO MAJOR EIR REVISIONS REQUIRED DUE TO CHANGE IN
CIRCUMSTANCES
There are no substantial changes that have or will occur with respect to the circumstances under which the project is undertaken which would require major revisions of the Certified EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects, for reasons detailed in Section 5.1, No Major EIR Revisions Required Due to Environmental Effects.
5.3 NO NEW INFORMATION OF SUBSTANTIAL IMPORTANCE
There is no new information of substantial importance known and could have been known with the exercise of reasonable diligence at the time the previous EIR was certified as complete, in that:
1. The key circumstances and assumptions to which the Certified EIR was completed have not changed. The amendments are consistent with the environmental impact analysis, findings, and mitigation in the Certified EIR; and
2. Mitigation measures in the Certified EIR Mitigation Monitoring and Reporting Program shall be incorporated as feasible mitigation measures for the project.
5.4 EIR ADDENDUM IS APPROPRIATE DOCUMENTATION
Although there are no substantive changes to the project, an addendum is appropriate because the project involves minor changes and new information related to the Centennial General Plan (State CEQA Guidelines §§15162, 15164). This information does not constitute substantial changes to the project or the circumstances due to the involvement of significant environmental effects or a substantial increase in the severity of previously identified significant effects. Similarly, subsequent consideration does not constitute new information that would show new effects or Final 74 May 2022
West Pico Corridor Specific Plan Update and Architectural Overlay Expansion Centennial General Plan EIR Addendum No. 4
substantially more severe effects. Likewise, there are no known mitigation measures that would in fact be feasible or that would substantially reduce significant effects that the project proponent has declined to adopt. Furthermore, there have been no other changes, evidence or new information, which would require revisions to the Certified EIR. In accordance with State CEQA Guidelines Section 15164, this Addendum to the certified Centennial General Plan Final Environmental Impact Report is the appropriate environmental document for the proposed project.

Date: May 24, 2022
Subject: West Pico Corridor Specific Plan Update & General Plan Amendment Transportation Analysis Introduction
Michael Baker International (Michael Baker) prepared this technical memorandum to provide a transportation analysis for the proposed West Pico Corridor Specific Plan Update (Project) located in the City of San Clemente, California. This City-initiated project includes a General Plan Amendment (GPA) 21-238, Specific Plan Amendment (SPA) 21-239, and Zoning Amendment (ZA) 21-240. The purpose of this transportation analysis is to address the proposed land use change related to the "split-zoned" industrial property at 1510 Avenida De La Estrella within the Specific Plan. The Project would change the General Plan land use designation of 1510 Avenida De La Estrella from a split of "Heavy Industrial (HI) and Light Industrial (LI) to be entirely "Heavy Industrial". This analysis focuses on the portion of the property that is currently zoned "Light Industrial" which consists of approximately 48,719 square feet (SF). Table 1 provides key project information.
Exhibit I shows the location of the project and proposed land use changes.

The transportation analysis includes two components: vehicle miles traveled (VMT) analysis to comply with the California Environmental Quality Act (CEQA) process and traffic operations analysis based on level of service (LOS) to comply with the County's requirements. The City of San Clemente does not have their own transportation impact study guidelines.
Therefore, the County of Orange's 2020 Updated Transportation Implementation Manual (County of Orange TIM) amended November 17, 2020 was utilized as a resource for the VMT assessment and LOS analysis in this technical memorandum.

Trip Generation Summary
The Institute of Transportation Engineers (ITE) Trip Generation Manual, 11'h Edition was used to estimate the number of daily and AM/PM peak hour trips generated by the land use in the current General Plan and the land use under consideration with the General Plan Amendment at 1510 Avenida De La Estrella. Table 2 provides the trip generation rates assumed for the site. General light industrial is the existing land use and manufacturing represents the proposed land use since "heavy industrial" is not a designated land use category in the ITE Trip Generation Manual.

(1) General Light Industrial is allowed a maximum density of 0.5 FAR. (2) South Coast Air Quality Management District (SCAQMD) assumes industrial uses generally consist of 69% passenger cars and 31% trucks. (3) A PCE factor of 2.5 was assumed to account for heavy vehicles per the County of San Diego Transportation Study Guidelines, June 2020. (4) Manufacturing (Heavy Industrial) is allowed a maximum density of 0.75 FAR.
KSF = 1,000 Square Feet

The proposed General Plan Amendment would increase the maximum allowed density of 48,719 SF of property from 0.50 floor area ratio (FAR) to 0.75 FAR, resulting in a density increase of 12,180 SF. In Table 5, the General Light Industrial shows 24,360 SF which is based on an 0.5 FAR (48,719 SF x 0.50). The Manufacturing shows 36,540 SF in Table 3 which is based on a 0.75 FAR (48,719 SF x 0.75).
Larger vehicles such as trucks are generally associated with industrial type uses. According to the South Coast Air Quality Management District (SCAQMD), industrial facilities generally consist of 69% passenger vehicles and 31% trucks. As such, the trips associated with the existing General Plan and proposed General Plan Amendment were broken down by vehicle type i.e. passenger cars and trucks.
In addition, a passenger car equivalency (PCE) factor was applied to these land uses to account for trucks. Since trucks tend to have more significant effect on roadway operations when compared to passenger vehicles, passenger car equivalency (PCE) factors were applied to convert truck traffic to passenger car equivalents. PCE factors are not provided in County of Orange TIM and so a PCE factor of 2.5 was applied only to the truck trips using the County of San Diego's Transportation Study Guidelines since they are a neighboring County that recommends a PCE factor to account for truck trips.
VMT Screening Criteria
According to the County of Orange TIM, CEQA analysis requires an evaluation of potential transportation impacts related to VMT. Screening criteria to determine if a project is anticipated to result in a less-than-significant transportation impact along with VMT metrics and thresholds of significance are included in the County of Orange TIM. Projects that meet the VMT screening criteria identified in Table 4 are assumed to result in a less-than-significant transportation impact under CEQA and do not require a detailed quantitative VMT analysis. Michael Baker has conducted an evaluation of the VMT screening criteria and has determined that the General Plan Amendment meets two of the Screening Criteria.
Therefore, a detailed VMT assessment is not required, and the VMT impact is considered less-than-significant on the environment.

Intersection Operations Analysis
The General Plan Amendment is estimated to generate 10 AM and 15 PM peak hour trips as a result of the land use change from General Light Industrial to Heavy Industrial ie. Manufacturing. It may be noted the site is fully developed and the land use change would not affect the existing trips generated by the site. Trips from the developed site are already considered in the existing traffic counts, therefore, the analysis focuses on the net change in potential trips as a result of the land use change. An intersection operational analysis was conducted at two intersections near the Project site to determine if the additional traffic would negatively affect intersection operations. The two intersections evaluated in this analysis were:
1) Calle De Los Molinos & Avenida Pico (Signalized)
2) Calle De Los Molinos & Avenida De La Estrella (All-Way Stop Control) Traffic Count Data
To determine the existing operations at the two study intersections, AM and PM peak hour intersection turning movement counts were collected on Wednesday, February 9, 2022. AM peak period counts were collected from 7:00 to 9:00 AM and Michael Baker 6| Page

PM peak period counts were collected from 4:00 to 6:00 PM. The counts used in this analysis were taken from the highest hour within the peak periods. Pedestrian and bicycle counts were also collected at each intersection during the AM and PM peak periods. Exhibit 3 shows the existing AM and PM peak hour traffic volumes at the study intersections. Detailed traffic count data is contained in Appendix A of this memorandum.

Intersection Operations Analysis
For analyzing intersections, the County of Orange requires the Intersection Capacity Utilization (ICU) methodology be used. ICU is a percentage that relates the relative capacity of an intersection to accommodate vehicular traffic where a value of 100% means the intersection is at capacity and likely experiences congestion for one hour. The ICU calculations were performed in the Synchro program and the results are provided in Table 5 presenting the ICU and LOS results for the Existing Conditions at both study intersections for the 2010 Base Year condition and Year 2022 condition. The ICU and LOS results for the 2010 Base Year condition at Calle De Los Molinos & Avenida Pico were obtained from the City of San Clemente's General Plan Update Environmental Impact Report (EIR), Appendix G (Mobility Report). It may be noted the all-way stop controlled intersection at Calle De Los Molinos & Avenida De La Estrella was not evaluated in the City's General Plan Update and therefore, the no results are provided for the 2010 Base Year conditions.

AWSC = All-Way Stop Control
LOS = level of service.
As shown, both intersections currently operate at LOS A, which is considered acceptable operating conditions in the County of Orange and the City of San Clemente. The net increase in traffic associated with the change in land use was assumed to have a similar distribution and travel pattern as trip characteristics of the existing use on the site. At Calle De Los Molinos & Avenida De La Estrella, the majority of existing traffic (80%) in the westbound approach is turning right (northbound towards Avenida Pico). At Calle De Los Molinos & Avenida Pico, the majority of existing traffic (80%) in the northbound approach turns right (eastbound towards Interstate 5. For purposes of this analysis, we assumed 100% of project traffic exiting the project site makes a westbound right-turn onto Calle De Los Molinos and then travels north to then make a right-turn at Avenida Pico and vice-versa traveling to the project site from Interstate 5.
Traffic volumes from the General Plan Amendment were added to existing traffic volumes to derive the Existing Plus General Plan Update peak hour traffic volumes shown in Exhibit 3. Table 6 presents the Existing Plus General Plan Amendment AM and PM peak hour LOS for both study intersections. As shown, both intersections are forecast to operate at LOS A with the addition of Project traffic. Detailed ICU worksheets for both the Existing and Existing Plus General Plan Amendment conditions are provided in Appendix B of this memorandum.

Future Conditions (Year 2035)
The City's 2010 General Plan Update Environmental Impact Report (EIR) evaluates the Future Conditions assuming a buildout year of 2035. Within the Future Conditions analysis, the City's General Plan Update analyzed a Preferred General Plan scenario which allowed for greater density development ranging from office to mixed-use development throughout the focus areas of the City. Allowing for greater density generates additional traffic to the circulation network which could negatively affect intersections near these developments and along major routes of travel. The Preferred General Plan scenario included an alternative with the completion of the Foothill Transportation Corridor (FTC). The FTC is the extension of State Route 241 (SR-241) from Oso Parkway to Cow Camp Road which was completed in 2019. Therefore, the Future Conditions (Year 2035) in this analysis is based on the Preferred General Plan With FTC scenario.
Year 2035 peak hour traffic volumes at Calle De Los Molinos & Avenida Pico were taken from the City's 2010 General Plan Update and used to evaluate intersection operations. According to the 2010 General Plan EIR, Calle De Los Molinos & Avenida Pico is forecast to operate at LOS F during the PM peak hour under Future Conditions (Year 2035). LOS E or F is considered unacceptable intersection operating conditions according to the City of San Clemente. Therefore, mitigation was required at this intersection to improve operating conditions to LOS D or better. Recommended improvements included restriping the Calle De Los Molinos northbound approach to have one shared through-left turn and one right- turn lane with signal modifications. This mitigation measure has already been implemented at Calle De Los Molinos & Avenida Pico and therefore included in the Future Conditions (Year 2035) analysis. As shown in Table 7, this intersection is forecast to operate at LOS D in the Future Conditions (Year 2035). Therefore, no further improvements are needed at this location.
The 2010 General Plan EIR does not evaluate the intersection of Calle De Los Molinos & Avenida De La Estrella. Therefore, AM and PM peak hour traffic volumes were developed assuming the growth from Year 2022 to Year 2035 at Calle De Los Molinos & Avenida Pico. The total growth from Year 2022 to Year 2035 was calculated to be 46% in the AM peak hour and 61% in the PM peak hour. This growth was applied to the Year 2022 peak hour volumes to derive the Future Conditions (Year 2035) peak hour volumes at Calle De Los Molinos & Avenida De La Estrella.

Detailed ICU worksheets for both the Future Conditions (Year 2035) and Future Conditions (Year 2035) Plus General Plan Amendment conditions are provided in Appendix C of this memorandum Conclusions
This transportation analysis addresses the proposed land use change (LI to HI) related to the "split-zoned" industrial property at 1510 Avenida De La Estrella within the Specific Plan. This change in land use along with the maximum allowed density increase from 0.5 FAR to 0.75 FAR results in 80 additional daily trips and 10 additional AM peak hour trips and 15 PM peak hour trips. In accordance with the County of Orange TIM, a detailed VMT analysis is not required since two of the VMT screening criteria are met. Therefore, the land use change is considered to have a less-than-significant transportation impact on the environment. In addition, the two study intersections are expected to operate at LOS A with the addition of traffic associated with the land use change. As such, intersection improvements are not required under Existing Conditions or Future Conditions (2035) with the proposed General Plan Amendment.
