INTRODUCTION. The California Environmental Quality Act (CEQA), Pub]ic Resources Code Section 21081, and the State CEQA Guideljnes, 14 Cal. Code of Regs. Section 15091 require that a public agency consider the environmental impacts of a project before a project is approved and make specific findings. CEQA Guidelines Section 15091 provides: (a) No public agency shall approve or carry out a project for which an EIR has been certified which identifies one or more significant environmental effects of the project unless the public agency makes one or more written findings for each of those significant effects, accompanied by a brief explanation of the rationale for each finding. The possible findings are: 1. Changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effect as identified in the Final EIR. 2. Such changes or alterations are within the responsibility and jurisdiction of another public agency and not the agency making the finding. Such changes have been adopted by such other agency or can or should be, adopted by such other agency. 3. Specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or alternatives identified in the final EIR. (b) The findings required by subsection (a) shall be supported by substantial evidence in the record. (c) The finding in subsection (a)(2) shall not be made if the agency making the finding has concurrent jurisdiction with another agency to deal with identified feasible mitigation measures or alternatives. The finding in subsection (a)(3) shall · describe the specific reasons for rejecting identified mitigation measures and project alternatives. (d) When making the findings required in subsection (a)(l), the agency shall also adopt a program for reporting on or monitoring the changes which it has either required in the project or made a condition of approval to avoid or substantially lessen significant environmental effects. These measures must be fully enforceable through permit conditions, agreements, or other measures. (e) The public agency shall specify the location and custodian of the documents or other materials which constitute the record of the proceedings upon which its decision is based. (f) A statement made pursuant to Section 15093 does not substitute for the findings required by this section. CEQA Guidelines Section 15093 further provides: (a) CEQA requires the decision-making agency to balance, as applicable, the economic, legal, social, technological; or other benefits of a proposed project against its unavoidable environmental risks in determining whether to approve the project. If the specific economic, legal, social, technological, or other benefits of a proposal project outweigh the unavoidable adverse environmental effects, the adverse environmental effects may be considered "acceptable". (b) Where the lead agency approves a project which will result in the occurrence of significant effects which are identified in the final EIR but are not avoided or substantially lessened, the agency shaJI state in writing the specific reasons to support its action based on the final EIR and/or other information in the record. This statement of overriding considerations shall be supported by substantial evidence in the record. ( c) If an agency makes a statement of overriding considerations, the statement should be included in the record of the project approval and should be mentioned in the notice of determination. This statement does not substitute for, and shall be in addition to, findings required pursuant to Section 15091. Having received, reviewed and considered the Final Subsequent Environmental Impact Report for the Brightwater Development Project, SCH No. 1993071064 (FSEIR), as weJI as all other information in the record of proceedings on this matter, the following Findings and Facts in Support of Findings (Findings) and Statement of Overriding Considerations (SOOC) are hereby adopted by the County of Orange (County) in its capacity as the CEQA Lead Agency. These Findings set forth the environmental basis for current discretiopary actions to be undertaken by the County for the implementation of the Brightwater Project. These actions include the approval of a Master Site/ Area Plan and approval of Project Site Development Plans. These actions are coJlectively referred to herein as the Project. A. Document Format These Findings have been organized into the following sections: 2 (1) Section 1 provides an introduction to these Findings. (2) Section 2 provides a summary of the Project and overview of the discretionary actions required for approval of the Project, and a statement of the Project's objectives. (3) Section 3 provides a summary of previous environmental reviews related to the Project area that took place prior to the environmental review done specifically for the Project, and a summary of public participation in the environmental review for the Project. ( 4) Section 4 sets forth findings regarding those environmental impacts which were detennined as a result of the Initial Study, Notice of Preparation (NOP) and consideration of comments received during the NOP comment period either not to be relevant to the Project or which were determined to clearly not manifest at levels which were deemed to be significant for consideration at the Project-specific level.

B. Custodian and Location of Records The documents and other materials which constitute the administrative record for the County's actions related to the Project are located at the County of Orange, Planning and Development Services Division (County PDSD), 300 N. Flower Street, 3rd Floor, Santa Ana, California 92703. County PDSD is the custodian of the administrative record for the Project. 2. PROJECT SUMMARY . A. Project Location The Project site is located within the unincorporated portion of the County in the west- central portion of the County. The majority of the 106.3 acre Project site is located in the County 3 of Orange (105.3 acres), with approximately 0.95 acres of the Project site Jocated within the corporate boundaries of the City of Huntington Beach. The Project site is located at Warner A venue and Los Patos A venue and is bounded on the north by Los Patos A venue and on the east by Bolsa Chica Street. B. Project Description The Project proposes the development of an approximately 106.3 acre area for residential development. The Project proposes the construction of 388 single family dwelling units on approximately 77.5 acres of the Project site. (Of the 388 residential dwelling units, 9 of the proposed dwelJing units are located on 0.95 acres that are either partially or wholly within the City of Huntington Beach. Because the City will have permitting authority over these nine units, the City is a Responsible Agency under CEQA.) The Project includes a buried water supply reservoir and pump station on 0.8 acres, 5 acres of Conservation Open Space to protect an environmentally sensitive habitat area (ESHA) designated under the California Coastal Act, and 23 acres of Recreation Open Space, including open space areas, trails, and wetland ponds. The Draft Subsequent EIR that was circulated for public review described and analyzed a project that proposed construction of 387 single-family dwelling units. Subsequent to the circulation of the Draft Subsequent EIR, the applicant, in response to technical design comments made minor revisions to the Site Plan for Development Area (DA) 7-1 and 3B (HOA Recreation Center/Underground Reservoir) and the Site Plan for DA 7-2 (Camden SFD Residential Area). The revisions reduce the size of the proposed reservoir site {Public Facility Development Area 4B) by approximately 0.1 acre and relocates the domestic water pump station building approximately 50 feet to the west, and correspondingly adds one residential lot of approximately 0.1 acre with one single-family dwelling unit to Development Area 7-2, thereby bring the total of proposed residential units to 388. An analysis of the revisions was included in the FSEIR which concluded that the proposed modifications do not present any new significant environmental effects, or require consideration of new mitigation measures or new alternatives not previously considered in the Draft Subsequent EIR. The Project site is designated under the County's General Plan, Land Use Element as lB Suburban Residential with an aUowable density of 0.5 to 18 dwelling units per acre. The Project site within the City of Huntington Beach is designated RL-7, Low Density Residential (up to 7 units per acre) under the City's General Plan. The existing zoning for the Project site is Bolsa Chica Planned Community (PC) Program for the County portion of the Project site, and Rl-C2, Low Density Residential (Coastal Zone Overlay) in the City of Huntington Beach. C. Discretionary Actions · The Project proponent, Hearthside Homes, has filed seven Planning Applications with the County PDSD pursuant to Section 10.3 of the Pla1U1ed Community Program and Section 7-9- 150.2 of the Orange County Zoning Code, including applications for the folJowing: PAOI 0070: Approval of a Master Site Permit/ Area Plan for the Brightwater Development Project area; 4 PA010082: Approval of a Project Site Plan Permit for Planning Areas 3A and 3B (Passive Recreation, and Open Space) PA010083: Approval of a Project Site Plan Pennit for Development Area 4B (Water Storage Reservoir) and pumping facility, and Development Area 7-1 (HOA Recreation Facilities) PA010084: Approval of a Project Site Plan Permit for Development Area 7-2 (78 Detached Residential Units) PA010085: Approval of a Project Site Plan Pennit for Development Area 7-3 (64 Detached Residential Units) PA010086: Approval of a Project Site Plan Permit for Development Area 7-4 (28 Detached Residential Units) PAOI0087: Approval of a Project Site Plan Pennit for Development Area 8 (218 Detached Residential Units) The Project proponent has also filed a Vesting Tentative Tract Map No. 15460 with the County of Orange for approval by the Orange County Subdivision Committee, pursuant to the California Subdivision Map Act and County Subdivision Ordinance. The vesting tentative tract map for the unincorporated portion of the Project site includes 379 residential lots. In addition to the discretionary actions described above, the applicant must also obtain one or more coastal development permits from the California Coastal Commission and the City of Huntington Beach in accordance with the requirements of the California Coastal Act. Implementation of the portion of the Project within the City of Huntington Beach will require several actions by the City, including • Approval of the Vesting Tentative Tract Map • Approval of a coastal development pennit pursuant to the City of Huntington Beach Local Coastal Program and the California Coastal Act for nine residential units • Approval of an annexation of approximately 0.65 acres on six of the proposed Jots that are currently bisected by the City/County boundary • Approval of a zone change for the RA zoned area within the portion of the Project site in the City to R 1. D. Statement of Project Objectives A number of Project-specific objectives have been fonnulated for the Project. These objectives include, but are not limited to, the following: 5 • Provide a mixture of housing on the project site • Develop distinctive residential neighborhoods with a mixture of residential densities and lot sizes within separate planning areas • Provide housing that will further the County's General Plan objectives for jobs/housing balance • Provide for the protection and maintenance of wetlands, ESHA, and marine resources while at the same time implementing community design and site planning concepts suitable for urban development • Provide recreational opportunities by creating public trails • Incorporate a pedestrian oriented circulation system with convenient linkages among neighborhoods, parks, and open space areas to facilitate the efficient movement of people • Provide local parks with variety of active and passive recreational opportunities • Create a pedestrian and bicycle oriented streetscape that residents can use for recreational purposes • hnplement the relevant policies and objectives outlined in the Orange County General Plan, the City of Huntington Beach General Plan, and the California Coastal Act. 3. ENVIRONMENTAL REVIEW AND PUBLIC PARTICIPATION The environmental review process for the Brightwater Development Project is summarized as follows: • In accordance with CEQA requirements, the County prepared an Initial Study and published a Notice of Preparation (NOP) of a Draft Supplemental Environmental Impact Report. The NOP was filed with the State Clearinghouse on July 20, 2001. Because the County determined that a Supplemental EIR was appropriate, the State Clearinghouse assigned the same State Clearinghouse Number 1993071064 for the document as the prior EIR 551 certified in 1996 by the County. • The NOP and Initial Study were distributed to alJ responsible and trustee agencies and other interested parties on July 20, 2001 for a 30-day public review. The review period ended on August 20, 2001. The Notice of Preparation, Mailing List, Comments Received and Notice of Preparation Scoping Summary are incJuded in the Project DSEIR at Appendix A. 6 As a result of comments received on the NOP and Initial Study, the County detennined that a Subsequent Environmental Impact Report, as described in Section 15162 of the CEQA Guidelines, should b.e prepared instead of a Supplemental Environmental Impact Report because substantial changes have occurred with respect to the circumstances under which the project is undertaken which will require major revisions of the previous EJR, the 1996 EIR 551, and those substantial changes included: • A substantial portion of the Bolsa Chica Lowlands has been purchased by the State of California, and restoration of the Lowlands is being planned for by State and federal government resource agencies. Development of the 800 residential units in the Lowlands has been eliminated. • Litigation over Sections 30233 and 30240 of the California Coastal Act has resulted in the revision of the Project described in 1996 EIR 551 to protect wetlands and environmentally sensitive habitat areas consistent with those court decisions. • The County's Local Coastal Program has not been certified by the Coastal Commission, and therefore, Coastal Act pennitting jurisdiction rests with the California Coastal Commission. • The City of Huntington Beach approved development of 16 residential units northwest of the proposed Brightwater Project site and these homes have been constructed and sold. The City is also considering an application from Shea Homes to construct a 49-acre site inunediately east of the Brightwater Project site. • In accordance with CEQA requirements, a Notice of Completion (NOC) of the Draft Subsequent EIR (DSEIR) and the DSEIR was filed with the State Clearinghouse on November 20, 2001. The DSEIR consisted of two volumes, including technical appendices. • The DSEIR was distributed to agencies, interested. organizations, and individuals by the County. A forty-five (45) day public review period for the DSEIR was established pursuant to CEQA which commenced on November 20, 2001 and ended on January 3, 2002. In response to comment letters expressing concern over the 45-day comment period, the County extended the comment period by two weeks and accepted comment letters through January 17, 2002. • Comments received during the public review period for the DSEIR were responded to in a Response to Comments document dated April, 2002, which was published by the County on April 22, 2002, as Volume ID Final Subsequent Environmental Impact Report, Brightwater Project, SCH No. 1993071064. • The FSEIR was distributed to responsible agencies and agencies submitting comments on April 25, 2002. 7 • The following components comprise the FSEIR on the Brightwater Development Project: (a) DSEIR Volume I and Volume II, dated November 17, 2001; (b) Comments received on the DSEIR and responses to those comments, published in Volume ID FSEIR, dated April, 2002; and ( c) All attachments, incorporations, and references to the documents delineated in items a. and b. above., and submitted to the County as part of the EIR process. • The County Planning Commission considered the FSEIR on the Brightwater Development Project at its hearing on May 8, 2002. The Brightwater FSEIR is a Subsequent Environmental hnpact Report. Section 15162 of the CEQA Guidelines, set forth in its entirety at page 2-2 of the FSEIR, Volume I, identifies when a subsequent environmental impact report should be prepared. As noted in the FSEIR, the environmental impacts of developing 2,500 residential units on Bolsa Chica Mesa (as well as development of 800 residential units on the Bolsa Chica Lowlands) were previously analyzed by . the County in EIR 551 (Orange County, 1996), which was prepared and certified by the County in connection with the amendment of the County Genera] Plan, adoption of planned community zoning, and adoption of a Local Coastal Program for the 1,600 acre Bolsa Chica property, which includes the I 06 acre Brightwater Project site. EIR 551 was a Program Environmental hnpact Report as described in Section 15168 of the CEQA Guidelines. Subsequent activities in the program must be examined in light of the program BIR to determine whether an additional environmental document must be prepared. The Brightwater Project is consistent with the County's General Plan and zoning adopted in connection with certification of EIR 551, but includes substantially fewer units than previously analyzed for the same site in EIR 551. The analysis of the proposed Project and environmental conditions is "tiered" from the analysis, and in accordance with Section 15168(c)(3), "[a]n agency shall incorporate feasible mitigation measures and alternatives developed in the program EIR into subsequent actions in the program." Many of the mitigation measures, project design features, and standard conditions identified in the Brightwater FSEIR are carried forward from EIR 551. Additionally, as noted in Section 15168(d}, the program EIR can be used to simplify the task of preparing environmental documents on later parts of the program. The program EIR can, among other things, "[b]e incorporated by reference to deal with regional influences, secondary effects, cumulative impacts, broad alternatives, and other factors that apply to the program as a whole." The alternatives discussion in the Brightwater FSEIR., for example, is tiered from the broader discussion of alternatives addressed in BIR 5 51. In addition, since the impacts of development of the entire Balsa Chica Mesa were analyzed comprehensively in EIR 551, this analysis was relied upon by the Brightwater FSEIR to assess the impacts of development of the entire Balsa Chica Mesa. 4. ENVIRONMENTAL EFFECTS WHICH WERE DETERMINED NOT TO BE POTENTIALLY AFFECTED BY THE PROPOSED PROJECT. 8 As a result of the Notice of Preparation circulated by the County on July 20, 200 l, the County detennined, based upon the threshold criteria for significance, that the Project would have no impact on the following potential environmental effects, and therefore, determined that . the these potential environmental effects would not be addressed in the DSEIR. Based upon the environmental analysis presented in the FSEIR, and the comments received by the public on the DSEIR, no substantial evidence has been submitted to or identified by the County which indicates that the Project would have an impact on the following environmental areas: (a) Agricultural Resources: There are no soils designated as prime fannland, unique farmland, or farmland of statewide importance on the Project site. The.Project would not result in the conversion of on-site or off-site fannland to a non-agricultural use. (b) Mineral Resources: There are no mineral resources of regional or Statewide importance within the Project site. (c) Population and Housing: The Project would not displace existing housing affecting a substantial number of people. (d) Geophysical: The Project does not propose septic systems therefore the DSEIR does not address whether the soils are capable of supporting septic tanks. The Project would not adversely affect any unique geologic or physical features. (e) Transportation/Circulation: The Project wilJ not affect rail, waterborne, or air traffic due to the absence of such facilities within the Project site. The Project has no effect on air traffic movement. (f) Air Quality: The Project is not of significant size or scope, and does not include the characteristics, such as tall buildings, to alter air movement and temperature or cause a change in climate. (g) Noise: There is no airport within two miles of the Project site so the Project will not be affected by excessive noise from airports. (h) Hazards: The Project is not within two miles of either an airport or private airstrip so the project would not result in a safety hazard for people residing or working in the Project area. 5. FINDINGS REGARDING POTENTIALLY SIGNIFICANT ENVIRONMENT AL EFFECTS The following potentially significant environmental impacts were analyzed in the FSEIR . . Where as a result of the environmental analysis of the Project and the identification of project design features, compliance with existing laws, codes and statutes, and the identification of feasible mitigation measures, the following potentially significant impacts have been determined by the County to be reduced to a level of less than significant, the County has found in accordance with CEQA Section 2108l(a)(l) and CEQA GuideJines Section 1509l(a) (1) that "Changes or alterations have been required in, or incorporated into, the project which mitigate or avoid the significant effects on the environment," which is referred to herein as "Finding I." 9 Where the potential impact can be reduced to less than significant solely through adherence to and implementation of project design features or standard conditions, these measures are considered "incorporated into the project" which mitigate or avoid the potentially significant effect, and in these situations, the County also will make •'Finding I" even though no mitigation measures are required. Where the County has determined pursuant to CEQA Section 2108l({a)(2) and CEQA Guidelines Section 15091 (a)(2) that "Those changes or alterations are within the responsibility and jurisdiction of another public agency and have been, or can and should be, adopted by that other agency, the County's findings is referred to herein as "Finding 2." Where, as a result of the environmental analysis of the Project, the County has determined that either (1) even with the identification of project design features, compliance with existing laws, codes and statutes, and/or the identification of feasible mitigation measures, potentiaJly significant impacts cannot be reduced to a level of less than significant, or (2) no feasible mitigation measures or alternatives are available to mitigate the potentially significant impact, the County has found in accordance CEQA Section 21081(a)(3) and CEQA Guidelines Section 15091 (a)(3) that "Specific economic, legal, social, technological, or other considerations, including considerations for the provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or alternatives identified in the environmental impact report," referred to herein as "Finding 3." A. Land Use (1) Potential Impact: The proposed Project has a Less Than Significant impact on land use as it pertains to conflicts with any applicable land use plan, policy or regulation of any agency with jurisdiction over the Project. Finding: The County hereby makes Finding 1 and determines that this potentia]]y significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: The proposed Project was evaluated against applicable policies of the Orange County General Plan, planned community zoning, City of Huntington Beach General ·Plan, Local Coastal Program and zoning,. Based upon that analysis, the Project will not create any conflicts or inconsistencies with applicable plans. A detailed discussion of the Project's consistency with the County's and City's General Plans and zoning was incJuded in Section 4.1 of the FSEIR. The following is a brief summary of several key points of the discussion. The Project is consistent with the General Plan designation and zoning for the site. The Project provides residential development in close proximity to jobs and commercial centers thereby he1ping to ameliorate the County-wide shortage of housing. Public works and infrastructure needed to support the Project will be implemented according to applicable codes and standards, including incorporation of water and energy conservation measures. The design and location of surface and subsurface drainage systems and 10 wastewater systems will ensure that impacts to coastal resources and wetlands will be minimized. SC 1-1 and SC 1-2 will ensure that staffing and faci1ities for public services are available to meet residents' needs. The proposed Project is . consistent and compatible with surrounding residential development. The Project proposes a landscaped open space transition area between the development and adjacent areas pursuant to PDF 1-1. The protection of significant open space is achieved through compliance with SC 1-4 through SC 1-7. As local parks are an important component of new development, PDF 1-2 provides for implementation of the Local Park Implementation Plan to identify park and recreational areas. With respect to the City's General Plan, the Project is consistent with the City's General Plan designation and zoning. As with the County, development of housing helps the City meet its housing objectives. Access to and through the site will be provided by a network of multiuse trails and sidewalks which provide an alternative to cars which is consistent with City's Land Use Element Objective 9.3.2. Implementation of SC I-8 provides the applicant options to satisfy the City's and County's affordable housing needs. PDF 1-1 PDF 1-2 SC 1-1 Transition Area. A Community Transition/Urban Edge Treatment Plan is provided as part of the Site Plan for the Project site. The plan includes an open space/buffer as a transition area between residential development and the Eucalyptus ESHA and a Jandscaping plan for the edge of the new development adjacent to existing homes along Los Patos A venue. The component of the plan adjacent to the lower mesa will include a passive open space area with 1) native plant revegetation, 2) public trail system, 3) fencing and signage, and 4) constructed and protected wetlands. Local Park Implementation Plan. A Bolsa Chica Local Park Implementation Plan (LPIP) shall identify requirements and locations for local park sites and recreation areas within the planned community and shall include an implementation program. The LPIP will implement all applicable local park policies set forth in Orange County's Local Park Code (i.e., County Ordinance No. 3518), and be consistent with the Orange County Recreation Element's "Master Plan of Local Parks." Annual Monitoring Report. An Annual Monitoring Report (AMR) shalJ be prepared and submitted by the landowner/master developer each calendar year to the County Administrative Office and the Orange County Planning and Development Services Department. Submittal of an AMR is required for conformance with the Growth Management Program of the Land Use Element of the Orange County General Plan and the County's Annual Development Monitoring Program. 11 SCl-2 SC 1-3 SC 1-4 The Board of Supervisors, in the annual adoption of the Development Monitoring Program, may identify a significant imbalance between development projections and planned infrastructure. The Board of Supervisors may then defer subdivision approval within the planned community until measures capable of resolving the imbalances are proposed to, and approved by, the Board of Supervisors. The AMR wiJI be the Project proponent's opportunity to demonstrate mitigation measures and implementation strategies, which will ensure adequate infrastructure for the community. Fiscal Impact Fees. Prior to the issuance of building permits or the recordation of an associated final tract map, whichever comes first, all projects shall be required to pay development fees for any facilities for which an applicable fee program has been adopted by the Board of Supervisors as provided in Sections 7-9-700 through 7-9-713 and 7-9-316 of the Codified Ordinances of the County of Orange. This condition may be satisfied by entering into an implementation agreement with the County in a manner meeting the approval of the County Executive Officer. Buyer Notification Map. Prior to the issuance of any building permits for residential construction, the developer shall prepare a map denoting the existing and proposed land uses, arterial highways, and public facilities within the surrounding area for the approval of the Manager, Current Planning Services. The map content, display, and distribution shaJl be in accordance with the Buyer Notification Program guidelines listed in Board of Supervisors Resolution 82-1368 and available at the Development Processing Center. Private Local Park. 1. Prior to the recordation of an applicable subdivision map that creates building sites, the subdivider shall make an irrevocable offer to dedicate an easement over Lot(s) AC, AE, Z for private local park purposes to the County of Orange in a form approved by the Manager, Real Property, in consultation with the Manager, Current Planning Services. The subdivider shaJl not grant any other easement over the private park easement that is inconsistent with the local park uses, unless that easement is made subordinate to said Joca1 park easement in a manner meeting the approval of the Manager, Real Property, in consultation with the Manager, Current Planning Services. 2. Prior to the recordation of an applicable final subdivision map, the subdivider shall submit a preliminary concept plan of the 1? SC 1-5 · SC 1-6 proposed private recreation facilities to the Manager, Current Planning Services, for review and approval. Open Space Dedications. Prior to the recordation of each applicable subdivision map, the subdivider shall reserve open space Jots AI, AJ for granting in fee to a homeowner's association, who shall be responsible for their maintenance and upkeep in a manner meeting the approval of the Manager HBP/Program Management and Coordination. Resource Preservation Easement 1. Prior to the recordation of an applicable subdivision map that creates building sites, the subdivider shall dedicate an easement for resource preservation purposes over lot AL, contained in Planning Area 3B ESHA, to the County of Orange or. its designee in a manner approved by the Manager, Real Property, to the satisfaction of the Manager PFRD/HBP Program Management and Coordination. The subdivider shall not grant any easement(s) over the property subject to the resource preservation easement unless such easement(s) are first reviewed and approved by the Manager, Real Property, in consultation with the Manager HBP/Program Management and Coordination. Maintenance of the resource preservation easement area shall be the responsibility of the subdivider or assigns and successors and shall not be included in said easement offer. 2. Prior to the recordation of a subdivision map, the subdivider shall note ]imitations and restrictions for said easement by a reference on the final map to a previously recorded document or by a reference to a separate document recorded concurrent with the subject map in a manner meeting the approval of the Manager, Rea] Property, in consultation with the Manager PFRD/HBP Program Management and Coordination. 3. Prior to recordation of any applicable subdivision map or as determined by the Manager, HBP/Program Management and Coordination, the subdivider shalJ survey and monument all resource preservation easement dedications. The subdivider shall monument the property line of the dedication area(s) with durable, ·long lasting, high visibility markers at all angle points and line of sight obstructions to the satisfaction of the Manager PFRD/HBP Coastal and Historical Facilities. 13 SC 1-7 SC 1-8 Private Area Landscaping I. Prior to the issuance of precise grading permits, the applicant shall prepare a detailed landscape plan for privately maintained areas, which shall be reviewed and approved by the Manager, Subdivision and Grading. The plan shall be certified by a licensed landscape architect or a licensed landscape contractor, as required, as talcing into account approved preliminary landscape plan (if any), Courity Standard Plans, adopted planned community regulations, scenic corridor and Specific Plan requirements, Grading and Excavation Code erosion control requirements, Subdivision Code, Zoning Code, and conditions of approval, Water Conservation Measures contained in Board Resolution 90- 487 (Water Conservation Measures), and Board Resolution 90- 1341 (Water Conservation hnplementation Plan). Said plan shall be reviewed and approved by the Manager, Subdivision and Grading. 2. Prior to the issuance of certificates of use and occupancy, applicant shall install said landscaping and irrigation system and shall have a licensed landscape architect or licensed landscape contractor certify that it was installed in accordance with the approved plan. 3. Prior to the issuance of any certificates of use and occupancy, the applicant shall furnish said installation certification, including an irrigation management report for each landscape irrigation system, and any other implementation report determined applicable, to the Manager, Building Inspection Services. Affordable Housing. Prior to recordation of a final map within the City of Huntington Beach, the applicant must satisfy the City's policy requiring that ten percent of the proposed units be affordable. This requirement must be satisfied at the discretion of the City Planning Department through one of the following methods. a. Pay a fee to the City, if such a process is available; b. Participate with other developers or a nonprofit organization to acquire and/or rehabilitate existing apartment units at any off-site location within a suitable area and provide for continued affordability; or •• c. Provide the required affordable unit and/or equivalent credit at a future multifamily project within the City of Huntington Beach. (2) Potential Impact: The proposed Project has a Less Than Significant impact on land use as it pertains to developing, eliminating or converting an appJicable General Plan designated open space or recreation area to a more intensive land use. Finding: The County determines that this potentially significant impact is Less Than Significant and that no project design features, standard conditions of approval, or mitigation measures were required or recommended. Facts in Support of Finding: The Project site is located within the larger Bolsa Chica property. Over 75% of the total 1,600 acre property is now owned by the State of California. This has resulted in potentially developable acres being converted to open space uses. The Project site is privately-owned and has been designated for residential development under the County's General Plan since the 1980's, and consequently will not result in the conversion of open space areas to development. (3) Potential Impact: The proposed Project has a Less Than Significant impact on land use as it pertains to physically dividing an established community. Finding: The County determines that this potentially significant impact is Less Than Significant and that no Project design features, standard conditions of approval, or mitigation measures were required or recommended. Facts in Support of Finding: The Project site is an extension of existing residential development which currently exists along the northern part of the site boundary. As a single family development that is located adjacent to other existing single family development, the Project does not divide an. established community but extends the community character onto the Project site. (4) Potential Impact: The proposed Project has a Less Than Significant impact on ]and use as it does not present a substantial conflict with an existing on site land use, particularly uses for recreational or scientific purposes. Finding: The County determines that this potentially significant impact is Less Than Significant and that no project design features, standard conditions of approval, or mitigation measures were required or recommended. Facts in Support of Finding: The Project site is presently vacant and is not used for recreational purposes. Although scientific work, in the form of archaeological excavations are currentJy being conducted on site, this work will be completed prior to development occurring, and therefore, this is not considered a conflict. The Project will provide new recreational areas for the public and will enhance passive recreational and natural open space opportunities. 1 c:; (5) Potential Impact: The proposed Project has a Less Than Significant impact and does not cause a substantial conflict with existing adjacent land uses, including substantial incompatibility with significant wildlife, recreation and hazard areas. Finding: The County determines that this potentially significant impact is Less Than Significant with the implementation of standard conditions. No project design features or mitigation measures were required or recommended. Facts in Support of Finding: The Project site is compatible with adjacent land · uses, inc]uding residential to the north and east of the Project site, and open space areas along the portion of the site that is adjacent to the eucalyptus ESHA. The Project provides setback, buffering and protection for habitat areas including wetlands and the eucalyptus ESHA. There are no recreation uses on the Project site at present, but the Project wilJ greatly enhance recreational opportunities and access to natural open space areas by providing trails and parking areas. Compliance with the following standard conditions requiring adherence to the Uniform Building Code and State Alquist-Priolo Act ensures that Project site hazards are minimized. SCJ-4 SC3-5 The Project applicant shall design and construct alJ structures in accordance with mandated current UBC requirements. The proposed project shall avoid construction of habitable structures within areas subject to the potential hazard of surface fault rupture, incorporating appropriate setbacks determined by site specific studies, in accordance with the Alquist-Priolo Special Studies Zone Act of 1972 (Hart, 1989). (6) Potential Impact: The proposed Project has a Less Than Significant impact and does not cause a substantial conflict with the California Coastal Act. Finding: The County determines that this potentially significant impact is Less Than Significant with implementation of project design features. No standard conditions of approval or mitigation measures were required or recommended. Facts in Support of Finding: The Project site is within the California coastal zone and subject to regulation under the California Coastal Act. For areas that are not included within a certified local coastal program, development must be consistent with the policies of Chapter 3 of the Coastal Act. A detailed discussion of the Project's consistency with applicable Coastal Act policies is included in Section 4.1 of the FSEIR; however, the following is a brief summary of several key issues. The Project is consistent with Section 30230 that requires the maintenance and protection of marine resources and Section 30231 that requires the maintenance of coastal waters, streams and wetlands. The Project avoids all impacts to wetlands on the Project site and enhances the quality of the wetlands through management of urban runoff. In addition, the Project's water quality plan 1£ assures that impacts to marine resource areas, such as Outer Bolsa Bay, are minimized through implementation of best management practices. The Project is consistent with Section 30233 in that no wetlands are proposed for filling. The Project is consistent with Section 30240 in its protection and buffering of the eucalyptus ESHA. The project design features that are being implemented to address ORA-83 are consistent with Section 30244 of the Coastal Act requiring reasonable mitigation measures to protect archaeological and paleontoJogical resources. Section 30250 requires new development to be located contiguous to or in close proximity to existing developed areas. The proposed Project is an extension of the Sandover development and lies in close proximity to existing residential areas along Bolsa Chica .Street and Los Patos. The scenic and visual qualities of the coastal zone are protected through compliance with project design features that require landscaping and buffering of the site. In addition, over 23 acres of natural open space are being provided on the Project site overlooking the lowland area. Public access is greatly enhanced by the Project through the provision of new street.s and parking area, trails and the dedication of 23 acres of natural open space for passive recreational uses. PDF 11-1 PDF 11-2 The research design for recovered material analysis for the Bolsa Chica Region currently in preparation shall be completed. The research design shall contain a discussion of important research topics for recovered material analysis that can be addressed employing data from the Bolsa Chica sites. The research design shall be reviewed by at lea~t three qualified archaeologists as required by the California Coastal Commission Guidelines. A data recovery program shall be implemented and completed for important or unique archaeological resources in areas proposed for urban development on Bolsa Chica Mesa and for proposed urban development and wetlands restoration. The scope of work for the data recovery excavations shall be determined by the project archaeologist and reviewed and approved by the three qualified peer reviewer archaeologists established pursuant to CCC permit conditions. The data recovery excavations shall be completed prior to issuance of a grading permit and shall be monitored by a qualified Native American. The data recovery program shall be considered complete when the peer review group concludes that the data recovery excavations have been completed in accordance with its approved scope of work. Once data recovery excavations have been completed, a report of the data recovery program shall be prepared by the project archaeologist and reviewed by the peer review team, and submitted to appropriate governmental and academic institutions. Data recovery investigations, testing, analysis, and reports shall be completed at the Applicant's expense. 17 PDF 11-3 For ORA-83, prior to any grading activity at this site, a controlled grading program shall be conducted by the project archaeologist in the field area to recover any cogged stones or other important artifacts that may remain in this disturbed portion of the site. The controlled grading program shall be monitored by a qualified Native American. PDF 11-4 In addition to compliance with the standard condition set forth below, which requires that a County certified archaeologist be retained to establish procedures for archaeological resource surveillance prior to grading and to monitor grading within 500 feet of all recorded archaeological sites, the project applicant shaJI also retain a qualified Native American to monitor all grading activities monitored by the County certified archaeologist on Bolsa Chica Mesa. PDF 11-5 A reburial agreement has been executed between the project applicant and the Juaneno Band of Mission Indians regarding the treatment and disposition of prehistoric Native American human remains discovered at ORA-83, and reconunendations on the treatment and disposition of the human remains have been obtained from the other most likely descendants. If any additional prehistoric human remains are discovered on the Bolsa Chica Mesa, this agreement shaIJ be extended to cover the treatment and disposition of those remains. PDF 10-2 A continuous and unbroken landscape lot will be provided along the entire length of Los Patos A venue to match the existing unbroken landscaped conidor and pedestrian walkway, which is part of the adjacent Sandover project southwest of the intersection of Bolsa Chica Street and Los Patos A venue. The vegetation will include trees, shrubs, and groundcover as well as a meandering sidewalk. PDF 10-4 The portions of the project site visible from publicly owned areas wiU be softened and extensively enhanced in rich native landscaping, incorporating the eucalyptus ESHA, and the freshwater ponds to be created on the project site's southern periphery, including the planting of coastal bluff scrub on the separator slope between the upper and lower mesas. B. Population and Housing (1) Potential Impact: hnpacts are considered significant if the proposed Project would cause a significant exceedance of the subregional projections; significantly worsen the jobs/housing balance within the region; introduce urban development that is incompatible with surrounding facilities or is located in an area not suitable Hl for future growth; or substantially increase population in excess of regional and subregional growth projections, such as OCP-2000 or the growth projections of the Southern California Association ofGovenunents (SCAG). Finding: The County determined that this impact was Less Than Significant, and that n~ mitigation measures were required or recommended. Facts in Support of Finding: Although the Project will contribute to a minor increase in population, housing and temporary employment, the Project will not cause an exceedance of subregional projections. As with the analysis of population increases in excess of regional and subregional growth projections, the Project is considerably smaller than the level of development currently reflected in the Orange County General Plan for this Project area. Growth and population projections are based, in large measure, on the buildout anticipated in applicable General Plans. In 1996, the Orange County General Plan was amended to provide for the development of 2,500 residential unit on Bolsa Chica Mesa, which includes the Project site. In 1997, the County revised the maximum number of residential units for Bolsa Chica Mesa to 1,235 residential units. The · Project proposes the development of 388 residential units which is well within the maximum level of development anticipated for this area under subregional and regiona1 growth and popu]ation projections. With respect to whether the Project would significantly worsen the jobs/ housing balance, the Project area is within a jobs rich area, and the proposed project will make a minor contribution towards improving the jobs/housing ratio. Both the County of Orange and the Northwest Orange Subregion #17 are considered jobs rich. The Project helps maintain the current CAA 34 jobs/housing ratio, and is consistent with SCAG's Growth Management Program jobs/housing balance policy through provision of housing in a jobs rich region. The Project is aJso consistent with the County's Housing Element objectives. Finally, the proposed Project does not introduce urban development that is incompatible with surrounding faciJities. The Project is consistent with the County General Plan and zoning, and is surrounded by residentiaJ areas. ConsequentJy, the Project can rely on and utilize existing infrastructure, such as streets and utilities. The Project ·is located in a residentially-developed area and the Project site has been proposed for residentia1 uses since the County's for Land Use Plan/Local Coastal Program was adopted in 1985. C. Geology and Seismicity (1) Potential Impact: The Project has a Less Than Significant impact as it pertains to the need for off-site import of earthen material or gravel of more than 100,000 cubic yards per year for development activities through compliance with PDFs and SCs. The Project will not import any materials for grade or elevation modifications or other deve1opment activities. 19 Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant through the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: The Project will not import any materials for grade or elevation modifications or other development activities. The Project's proposed grading plans calls for the export of approximately 220,000 cubic yards of material to the adjacent Shea Homes site. If the Shea Homes project is not constructed, the 220,000 cubic yards of material will be utilized on site. SC3-1 and SC3-2, set forth below require the preparation and review of a geotechnical report, including a slope stabilization plan and requirements to address soil conditions for development pad and slopes in the event that grading plans are to be revised to address the balancing of cut and fill on the Project site. SC 3-1 SC 3-2 SC 3-3 Prior to the issuance of a grading permit for grading on the Balsa Chica Mesa, the applicant shall submit a geotechnical report to the Manager, Development Services, for approval. The report shall include the information and be in a form as required by the Orange County Grading Manual, Section 5.4, and the Orange County Excavation and Grading Code Section 7-1-819 (corresponds to County of Orange, Standard Conditions of Approval GO 1, Geotechnical Report). The Project applicant's grading plan shall provide stabilization of manufactured slopes to the satisfaction of the Manager, Development Services, and may include, but is not limited to, buttressing of fills, rock bolting, grouting, slope gradient laybacks, and construction of retaining walls; and for natural slopes, use of drainage control and establishing vegetation. The applicant shall incorporate measures to mitigate expansive soil conditions, compressible/collapsible soil conditions, and impacts from trenching as outlined in a site specific Tentative Tract Map Review and Rough Grading Plan Review reports prepared by the project geotechnical consultant. Recommendations shall be based on surface and subsurface mapping, laboratory testing, and analysis. The geotechnical consultant's site specific reports shall be approved by a certified engineering geologist and a registered civil engineer and shall be completed to the satisfaction of the County. (2) Potential Impact: The Project has a Less Than Significant impact as it pertains to the potential exposure of people to geologic hazards, such as landslides, mudslides, seismic related ground failure, or substantial erosion, or soil and/or seismic conditions as a result of implementation of PDFs and SCs. 20 Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant through the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: The proposed Project incorporates the standards outlined in the County's Grading Manua] and Excavation and Grading Code. Before grading pennits are issued, a geotechnical study must be submitted to the County demonstrating the measures by which any unstable soil or other geological conditions will be remedied. Since the Project site is relatively flat, landslides or mudslides are not anticipated. Erosion control measures (including those described in the Water Quality Section) during construction activities will assure that potential erosion impacts are minimized to a less than significant level. Finally, through implementation of PDF 3-1, no building or public works structures wilJ be placed immediately adjacent to slopes or other areas where seismically induced ground failure could occur. Implementation and compliance with SC3-1 and PDF 3-1 reduces this potential impact to Less Than Significant. SC 3-1 PDF3-1 Prior to the issuance of a grading permit for grading on the Balsa Chica Mesa, the applicant shall submit a geotechnical report to the Manager, Development Services, for approval. The report shall include the information and be in a form as required by the Orange County Grading Manual, Section 5.4, and the Orange County Excavation and Grading Code Section 7-1-819 (corresponds to County of Orange, Standard Conditions of Approval GOl, Geotechnical Report). Recommendations for site grading, soil preparation and stabilization as described in AMEC (2001) and in the final geology design report will be implemented to minimize potential effects of site geology on the proposed development. (3) Potential Impact: The Project has a Less Than Significant impact as it pertains to the location of structures on a fault known to be ·capable of rupture as delineated on the AJquist-Priolo Earthquake Fault Zoning Map, or based on substantial evidence of a known fault as a result of implementation of PDFs and SCs. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant through the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: The proposed Project does not provide for any habitable stricture, including the proposed domestic water reservoir and pipelines, within the setback zone established pursuant to the Alquist-Priolo Act. No planned utilities are within the recommended fault setback zone. SC 3-4 requires ?1 Project structures to be designed in accordance with mandated current Unifonn Building Code (UBC) requirements. PDF 3-1 requires incorporation of the site specific recommendations for essential facilities, such as the water reservoir, contained in the Geotechnical Report (AMEC 2001) to address potentiaJ ground acceleration impacts. Therefore, these potentially impacts are reduced to Less Than Significant through implementation of the following measures: PDF3-l ·· SC 3-4 SCJ-5 Recommendations for site grading, soil preparation and stabilization as described in AMEC (2001) and in the final geology design report will be implemented to minimize potential effects of site geology on the proposed development. The Project applicant shall design and construct all structures in accordance with mandated current UBC requirements. The proposed prc:>ject shall avoid construction of habitable structures within areas: subject .to the potential hazard. of surface fault rupture, incorporating appropriate setbacks determined by site specific studies, in accordance with the Alquist-Priolo Special Studies Zone Act of 1972 (Hart, 1989). (4) Potential Impact: The Project has a Less Than Significant impact as it pertains to the exposure of the public or structures to earthquake induced groundshaking capable of causing ground rupture, liquefaction, settlement, or surface cracks resulting in the substantial loss of use or loss of life through implementation of PDFs and SCs. Finding: The County hereby makes Finding I and determines that this potentiaJly significant impact is Less Than Significant through the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: The potential for future artificial cut and fill slopes to fail due to ground shaking is considered remove because the Project must comply with the requirements of the County Grading Manual and Grading Code as required by SC 3-1. AJJ structures will be constructed per County of Orange and UBC requirements as required by SC 3-3 and 3-4, as follows: SC 3-I Prior to the issuance of a grading permit for grading on the Bolsa Chica Mesa, the applicant shall submit a geotechnical report to the Manager, Development Services, for approval. The report shall include the infonnation and be in a form as required by the Orange County Grading Manual, Section 5 .4, and the Orange County Excavation and Grading Code Section 7-1-819 (corresponds to County of Orange, Standard Conditions of Approval GOl, Geotechnical Report) . .,., SC 3-3 SC3-4 The applicant sha11 incorporate measures to mitigate expansive soil conditions, compressible/collapsible soil conditions, and impacts from trenching as outlined in a site specific Tentative Tract Map Review and Rough Grading Plan Review reports prepared by the project geotechnical consultant. Recommendations shall be based on surface and subsurface mapping, laboratory testing, and analysis. The geotechnical consultant's site specific reports shall be approved by a certified engineering geologist and a registered civil engineer and shall be completed to the satisfaction of the County. The project applicant shall design and construct all structures in accordance with mandated current UBC requirements. (5) Potential Impact: The Project has Less Than Significant impact as it pertains to the location of development on soils incompetent for use as a foundation, such as expansive or corrosive soils. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant through the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: Geotechnical recommendations to· address the potential effects of expansive soils are set forth in the Geotechnical Report prepared for the Project, compliance with which is required by SC3-1, SC 3-3 and PDF 3-1. The recommendations of the Geotechnical Report also address measures to reduce the impact of corrosive soils to Less Than Significant PDF 3-1 SC 3-1 SC 3-3 Recommendations for site grading, soil preparation and stabilization as described in AMEC (2001) and in the final geology design report will be implemented to minimize potential effects of site geology on the proposed development. Prior to the issuance of a grading permit for grading on the Bo Isa Chica Mesa, the applicant shall submit a geotechnical report to the Manager, Development Services, for approval. The report shall include the infonnation and be in a form as required by the Orange County Grading Manual, Section 5.4, and the Orange County Excavation and Grading Code Section 7-1-819 (corresponds to County of Orange, Standard Conditions of Approval GOl, Geotechnical Report). The applicant shall incorporate measures to mitigate expansive soil conditions, compressible/collapsible soil conditions, and impacts from trenching as outlined in a site specific Tentative Tract Map Review and Rough Grading Plan Review reports prepared by the project geotechnical consultant. Recommendations shall be based on surface and subsurface mapping, laboratory testing, and analysis. The geotechnical consultant's site specific reports shall be approved by a certified engineering geologist and a registered civil engineer and shall be completed to the satisfaction of the County. D. Surface and Groundwater Hydrology (1) Potential Impact: The Project has a Less Than Significant impact as it pertains to causing substantial and adverse increased inundation and/or damage from water forces to the Project and other properties from improvements such as construction of barriers and structures, increase in impervious surfaces, diversion of rainfall runoff, or interference with rainfall collection and conveyance through implementation of PDFs and SCs. Finding: The County hereby. makes Finding l and detennines that this potentialJy significant impact is less than significant through the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: In its developed condition, the Project's eight drainage areas, as delineated in the hydrology study prepared for the Project, will flow in Huntington Harbour through the Warner Avenue storm drain, Bolsa Chica Street, and into the constructed wetlands for treatment or the proposed detention basin which will eventually drain to the isolated pocket area of the Bolsa Chica Lowland. The area draining to Huntington Harbour is reduced by 20.57 acres from the existing site conditions. Peak flows to Bolsa Chica Street are reduced by 87 percent. Project implementation will provide for satisfaction of the City's criteria for this location, and flooding in this area will be reduced. With respect to the remainder of the site drainage, the Project proposes that the entire runoff from the 85th percentile storm as weJI as the first flush from all storms (0. 75 inches in 24 hours) will be conveyed to the constructed wetlands for treatment which are designed to hold the volume of the first flush and outlet the water over a 40 hour period. The implementation of the following Project design features and standard conditions reduce this potential impact to Less Than Significant: PDF4-2 PDF4-3 The proposed Project includes a constructed wetlands and a detention basin to serve as Best Management Practices (BMPs) in accordance with the Orange County Municipal Stormwater Permit (Order No. 96-31, NPDES No. CAS618030) and the Orange County Drainage Area Management Plan (DAMP) (1993). The proposed storm drain system will collect and convey surface drainage from Areas A through E. Area A will discharge to an PDF4-7 SC4-l SC4-2 existing stonn drain at the intersection of Los Patos Avenue and Warner A venue, Areas B through D will discharge to the isolated pocket lowland, Area E becomes part of Area D, and Areas F and G (off-site areas) surface drain to Bolsa Chica Street at Los Patos Avenue. The Project design will incorporate grading to redirect 18.3 drainage acres away from Bolsa Chica Street and to the constructed wetlands. Prior to the recordation of a subdivision map (except maps for financing and conveyance purposes only) or prior to the issuance of any grading permits, whichever comes first, the following drainage studies shall be submitted to and approved by the Manager, Subdivision and Grading: A. A drainage study ofthe-Project, including diversions, off- site areas that drain onto and/or through the Project, and justification of any diversions; and B. When applicable, a drainage study evidencing that proposed drainage patterns will not overload existing storm drains; and C. Detailed drainage studies indicating how the Project grading, in conjunction with the drainage conveyance systems, including applicable swales, channels, street flows, catch basins, storm drains, and flood water retarding, will allow building pads to be safe from inundation from rainfall runoff, which may be expected from alJ storms up to and including the theoretical 100 year flood). This Standard Condition corresponds to County of Orange (2000) Standard Condition DOl. A. Prior to the recordation of a subdivision map (except maps for financing and conveyance purposes only) or prior to the issuance of any grading permits, whichever comes first, the applicant shaJI in a manner meeting the approval of the Manager, Subdivision and Grading: 1. Design provisions for surface drainage; and 2. Design all necessary storm drain facilities extending to a satisfactory point of disposal for the proper control and disposal of storm runoff; and 25 SC4-3 3. Dedicate the associated easements to the County of Orange, if determined necessary. B. Prior to the recordation of a subdivision map (except maps for financing and conveyance purposes only) or prior to the issuance of any certificates of use and occupancy, whichever occurs first, said improvements shall be constructed in a manner meeting the approval of the Manager, Construction (corresponds to County of Orange Standard Condition D02). Prior to the issuance of any grading permit and if determined necessary by the Manager, Subdivision and Grading, the applicant shall record a letter of consent from the upstream and/or downstream property owners permitting drainage diversions and/or unnatural concentrations. The form of the letter of consent shall be approved by the Manager, Subdivision and Grading Services, prior to recordation of the letter. This Standard Condition corresponds to County of Orange (2000) Standard Condition 003. (2) Potential Impact: The Project has a Less Than Significant impact as it pertains to substantially and adversely affecting, by depletion or recharge, a usable groundwater aquifer for municipal, private, or agricultural purposes. Finding: The County finds that the Project has a Less Than Significant impact and that no mitigation measures, project design features or standard conditions are required or recommended. Facts in Support of Finding: Although the Project wil1 increase the amount of impervious surfaces on the Project site, and increase the flow of drainage to the isolated pocket lowland, the Project will not adversely affect groundwater recharge. The on-site soils have a low infiltration rate which greatly reduces the recharge potential of the Project site. The semiperched aquifer and the Bolsa aquifer have both been impacted by sea water intrusion and do not provide beneficial uses. On a temporary basis, a water well will be drilled to provide water for grading and other non-potable construction uses. The amount of water drawn for construction uses will not have an adverse effect on water for municipal uses and will be approved by the Orange County Water District prior to commencement of drilling the well, and will comply with (3) Potential Impact: The Project has a Less Than Significant impact as it pertains to causing substantial on-site or off-site post construction erosion. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is less than significant through the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. 26 Facts in Support of Finding: In accordance with PDF 4-3, grading on the site will direct stonnwater flow into the underground stonn drain system consisting of a series of catch basins in the streets, drain lines, smart boxes and outlets to minimize on-site erosion. PDF 4-5 requires that open space areas will be landscaped with native plants to prevent soil erosion. Runoff from the developed Project site will be directed to the constructed wetlands where it will be retained for sedimentation removal, among other purposes. (PDF 4-2 and PDF 5-1) The detention basin proposed by the Project will be sized to contain a 100 year stonn event, and will help prevent erosion of the trail. Riprap will be installed at the culvert outlet to the isolated pocket lowland to protect the outlet of the culvert and minimize erosion per PDF 4-1. PDF 4-6 requires automatic rain gauges to be connected to irrigation controllers to prevent over-watering. SC 4-1 requires a Water Quality Management Plan to be approved by the County which wilJ include, among other things, the details of the stonnwater management program and Best Management Practices to minimize erosion. SCs 4-2, 4-3 and 4-4 require approval of the Project drainage plan by the County for confonnance with the Master Plan of Drainage and the Orange County Hydrology Manual. With implementation of the identified PDFs and SCs, this impact is Less Than Significant. PDF4-1 PDF4-2 PDF4-3 PDF4-4 PDF4-S The proposed project includes construction of riprap at the existing culvert outlet into the isolated pocket lowland to protect the outlet and minimize erosion. The proposed project includes a constructed wetlands and a detention basin to serve as Best Management Practices (BMPs) in accordance with the Orange County Municipal Stonnwater Permit (Order No. 96-31, NPDES No. CAS6 l 8030) and the Orange County Drainage Area Management Plan (DAMP) (1993). The proposed storm drain system will collect and convey surface drainage from Areas A through E. Area A will discharge to an existing storm drain at the intersection of Los Patos A venue and Warner Avenue, Areas B through D wiJI discharge to the isolated pocket lowland, Area E becomes part of Area D, and Areas F and G (off-site areas) surface drain to Bolsa Chica Street at Los Patos Avenue. Programs for maintenance, cleaning, and upkeep of storm drain structures, streets, and parking areas will be developed and implemented by the Homeowners' Association (HOA). The landscape plan for the proposed project includes the planting of native species in the open space areas on the perimeter of the development. Landscaping that incorporates drought resistant plants can reduce irrigation and maintenance requirements. Native 27 PDF4-6 SC4-1 SC4-2 species wm be adapted to the climate and require little supplemental irrigation. Automatic rain gauges connected to irrigation controllers shall be installed and maintained by the HOA. These will monitor rainfall volume and interrupt watering schedules in response to site specific rainfall conditions. Rain gauges will be located adjacent to controllers to facilitate monitoring by maintenance personnel. Use of drip and efficient low-flow irrigation emitters shall minimize irrigation requirements and over-irrigation. Prior to the recordation of a subdivision map (except maps for financing and conveyance pwposes only) or prior to the issuance of any grading pennits, whichever comes first, the following drainage studies shall be submitted to and approved by the Manager, Subdivision and Grading: A. A drainage study of the project, including diversions, off- site areas that drain onto and/or through the project, and justification of any diversions; and B. When applicable, a drainage study evidencing that proposed drainage patterns will not overload existing storm drains; and C. Detailed drainage studies indicating how the project grading, in conjunction with the drainage conveyance systems, including applicable swales, channels, street flows, catch basins, storm drains, and flood water retarding, will allow bui1ding pads to be safe from inundation from rainfall runoff, which may be expected from all stonns up to and including the theoretical 100 year flood). This Standard Condition corresponds to County of Orange (2000) Standard Condition DOl. A. Prior to the recordation of a subdivision map (except maps for financing and conveyance purposes only) or prior to the issuance of any grading pennits, whichever comes first, the applicant shall in a manner meeting the approval of the Manager, Subdivision and Grading: 1.

Prior to the issuance of any grading permit and if detennined necessary by the Manager, Subdivision and Grading, the applicant shall record a letter of consent from the upstream and/or downstream property owners permitting drainage diversions and/or unnatural concentrations. The form of the letter of consent shall be approved by the Manager, Subdivision and Grading Services, prior. to recordation of the Jetter. This Standard Condition corresponds to County of Orange (2000) Standard Condition D03. Prior to the issuance of any building permits, the applicant shall participate in the applicable Master Plan of Drainage in a manner meeting the approval of the Manager, Subdivision and Grading, including payment of fees and the construction of the necessary facilities. Prior to the recordation of a subdivision map (except maps for financing and conveyance purposes only), the subdivider shall participate in the applicable Master Plan of Drainage in a manner meeting the approval of the Manager, Subdivision and Grading, including payment of fees and the construction of the necessary facilities. This Standard Condition corresponds to County of Orange (2000) Standard Condition 004. (1) Potential Impact: The proposed Project has a Less Than Significant impact as it pertains to a potential violation or exceedance of water quality standards or waste discharge requirements leading to a substantial effect on the environment. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. 29 Facts in Support of Finding: The County is required under its municipal NPDES pennit to protect the beneficial uses of receiving waters. The County is to employ BMPs that reduce pollutant loadings to surface water from urban runoff to the maximum extent practicable. PDFs 5-1, 5-3, 5-4 and 5-5 describe nonstructural and structural BMPs to be incorporated into the project design, which are among those recommended in the municipal permit and the Drainage Area Management Plan. The Project is also required to comply with the :waste discharge requirements of the Statewide General Construction Activity Stormwater Permit and will be required to implement a SWPPP pursuant to SC 5- 2. Adherence to the requirements of the County required by SC 5-1, and the ·Grading and Excavation Code required by SC 5-3 will prevent significant amounts of sediment and other polJutants from leaving the Project site in runoff. Any construction dewatering wilJ comply with SC 5-4 to ensure that discharge impacts will not have a significant effect. The implementation of the following project design features and standard conditions reduce this potential impact to Less Than Significant: PDFS-1 PDFS-3 PDFS-4 PDF5-5 SC5-1 Structural Best Management Practices (BMPs) for the treatment of runoff prior to discharge to off-site locations will consist of a constructed wetlands composed of a series of three ponds for Areas Bl, B2, B3, and D; and catch basin inserts for Area A. Operational BMPs such as litter control, street sweeping, and proper disposal of animal waste, etc., of the on-site areas are included in the project design and will be implemented through the HOA, as outlined in the WQMP. A public awareness program will be developed concerning water quality for future homeowners. The program will emphasize the proper use of irrigation, fertilizers, and pesticides by homeowners and landscape contractors. The program will be implemented by the HOA, as outlined in the WQMP. The project has been designed to capture and filter the first flush (the initial 0.80 inch of rain in a 24 hour period) on site to reduce sediment, bacteria, and other water quality pollution before discharging surface flows to the off-site isolated pocket lowland (refer to the Hydrology/Water Quality Study for specific calculations). Prior to the recordation of any final tract map, or issuance of grading permits, as deemed appropriate by the Manager, Subdivision and Grading Services, the subdivider shall submit and obtain approval from the Manager, Subdivision and Grading, of a Water Quality Management Plan (WQMP), specifically identifying Best Management Practices (BMPs) that will be used on-site or off-site to control predictable pollutant runoff. This WQMP shall 30 SCS-2 SC 5-3 SCS-4 identify, at a minimum, the routine, structural and nonstructural measures consistent with the County NPDES permit as it now exists, and any subsequent amendment finally adopted by the SARWQCB having jurisdiction that may be legally applied to the project, which detai]s implementation of BMPS whenever they are applicable to a project, the assignment of long-term maintenance responsibilities (specifying the developer, parcel owner, maintenance association, lessee, etc.); and shall reference the location(s) of structural BMPs. The project shall at a minimum implement the provisions and commitments of the proposed DAMP submitted in September, 2000, or as changed by the SARWQCB (corresponds to Draft County of Orange Standard Condition WQOl [August 16, 2001]). Prior to issuance of any grading permits, the applicant shall submit evidence to the Manager, Subdivision and Grading, that the· applicant has obtairied coverage under the' NPDES statewide General Construction Activity Stormwater Permit from the State Water Resources Control Board (corresponds to County of Orange Standard Condition WQ04). All grading and construction activities associated with project implementation will adhere to the relevant conditions established by the Orange County Grading and Excavation Code. For example, the code requires, where necessary, that temporary and/or permanent erosion control devices be used to control erosion and sedimentation during the rainy season, from October 15 to April 15. Any construction dewatering conducted at the site shall comply with the SARWQCB General Waste Discharge Requirements for Discharges to Surface Waters which pose an Insignificant (De Minimus) Threat to Water Quality, Order No. 98-67 (CAG998001). (2) Potential Impact: The proposed Project has a Less Than Significant effect on the degradation of surface water quality. Finding: The County hereby makes Finding 1 and determines that this potentiaJJy significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recorrunended. Facts in Support of Finding: The majority of the project site will discharge to the vegetated treatment system located southwest of the proposed development. After leaving the treatment system, the runoff will be released to the isolated lowland pocket area and then to Outer Bolsa Bay. Surface runoff will not drain 31 directly into Outer Bolsa Bay, the Bolsa Chica Ecological Reserve or Warner A venue Pond, or the lowlands wetlands restoration area south of the EGGW Flood Control Channel as required under PDF 5-2. The constructed wetlands to which the site discharges will substantially reduce the amount of pollutants that will be discharged from the Project site. PDF 5-6 requires water quality monitoring to measure the effectiveness of the constructed wetland at removing pollutants of concern. PDF 4-5 requires water efficient landscaping and PDF 4-6 requires automatic rain gauges connected to irrigation controllers. Both of these features are incorporated into the project to reduce nuisance runoff during the dry season. PDFS-2 PDFS-6 PDF4-5 PDF4-6 The proposed storm drain system has been designed to ensure that project surface flows wiJI not drain directly into Outer BoJsa Bay, the Bolsa Chica Ecological Reserve, or the lowland wetlands restoration area. Wa~er quality monitoring will be conducted to determine the effectiveness of the constructed wetlands at pollutant removal. For three storm events each year for three years, water samples will be collected from the junction boxes that discharge runoff to the constructed wetlands (inlet sample) and at the discharge of the 24 inch pipe to the isolated lowland pocket (outlet sample). Toxicity tests will be conducted on the samples for constituents to be determined by the Manager, Environmental Resources Division, PFRD, and detailed in the WQMP. The Jandscape plan for the proposed project includes the planting of native species in the open space areas on the perimeter of the development. Landscaping that incorporates drought resistant plants can reduce irrigation and maintenance requirements. Native species will be adapted to the climate and require little supplemental irrigation. Automatic rain gauges connected to irrigation controllers shall be installed and maintained by the HOA. These will monitor rainfall volume and interrupt watering schedules in response to site specific rainfall conditions. Rain gauges will be located adjacent to controllers to facilitate monitoring by maintenance personnel. Use of drip and efficient low-flow irrigation emitters to minimize irrigation requirements and over-irrigation. (3) Potential Impact: The proposed Project has a Less Than Significant effect on the degradation of groundwater quality. Finding: The County finds that the Project has a Less Than Significant impact and that no mitigation measures, project design features or standard conditions are required or recommended. 32 Facts in Support of Finding: Although the project will increase the amount of impervious surfaces on the Project site, and increase the flow of drainage to the isolated pocket lowland, the project will not adversely affect groundwater recharge. The on-site soils have a low infiltration rate which greatly reduces the recharge potential of the Project site. The semiperched aquifer and the Bolsa aquifer have both been impacted by sea water intrusion and do not provide beneficial uses. On a temporary basis, a water well will be drilled to provide water for grading and other non-potable construction uses. The amount of water drawn for construction uses will not have an adverse effect on water for municipal uses and will be approved by the Orange County Water District prior to commencement of drilling the well. Adherence to the following standard conditions reduce groundwater impacts to less than significant. (4) Potential Impact: The proposed Project has a Less Than Significant effect as it pertains to substantially altering the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner that would cause substantial erosion or siltation during construction. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: There are no streams or river on the Project site that would be affected by the project. In the developed condition, most of the site will follow a drainage pattern similar to existing conditions, except for the northeastern portion of the site which will drain south to the constructed wetlands and away from Bolsa Chica Street and Huntington Harbour. The project will comply with the General Construction Activity NPDES permit and will submit and foJlow a SWPPP and Erosion Control Plan pursuant to SC 5-2. The project will incorporate construction level BMPs to prevent erosion and siltation of receiving waters pursuant to SC 5-1. Adherence to the following special conditions wi11 reduce construction erosion or siltation impacts to less than significant: SC5-1 Prior to the recordation of any final tract map, or issuance of grading permits, as deemed appropriate by the Manager, Subdivision and Grading Services, the subdivider shall submit and obtain approval from the Manager, Subdivision and Grading, of a Water Quality Management Plan (WQMP), specifically identifying Best Management Practices (BMPs) that will be used on-site or off-site to control predictable pollutant runoff. This WQMP shalJ identify, at a minimum, the routine, structural and nonstructural measures consistent with the County NPDES permit as it now exists, and any subsequent amendment finally adopted by the SARWQCB having jurisdiction that may be legally applied to the project, which details implementation of BMPS whenever they are 33 SC 5-2 applicab]e to a project, the assignment of long-term maintenance responsibilities (specifying the developer, parcel owner, maintenance association, lessee, etc.); and shalJ reference the location(s) of structural BMPs. The project shall at a minimum implement the provisions and commitments of the proposed DAMP submitted in September, 2000, or as changed by the SARWQCB (corresponds to Draft County of Orange Standard Condition WQOl [August 16, 2001]). Prior to issuance of any grading pennits, the applicant shall submit evidence to the Manager, Subdivision and Grading, that the applicant has obtained coverage under the NPDES statewide General Construction Activity Stonnwater Permit from the State Water Resources Control Board (corresponds to County of Orange Standard Condition WQ04). (5) Potential Impact: The proposed Project has a Less Than Significant effect as it pertains to substantialJy altering the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner that would cause substantial on-site or off-site postconstruction siltation. Finding: The County hereby makes Finding 1 and determines that this potentialJy significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts io Support of Fiodiog: The proposed Project includes PDFs (4-1, 4-4, 4-5 and 4-6) to reduce dry weather runoff and erosion that could lead to siltation of receiving waters. In addition, the constructed wetlands and catch basin inserts provided under PDF 5-1 will retain both pollutants and sediment. Per SC 5-1, the Project will be required to develop and implement a Water Quality Management Plan per Orange County Standards which wilJ identify additional BMPs. Implementation of the PDFs and SCs for this proposed project will reduce post- construction siltation impacts to less than significant levels. PDF4-1 PDF4-4 PDF4-5 The proposed project includes construction of riprap at the existing culvert outlet into the isolated pocket lowland to protect the outlet and minimize erosion. Programs for maintenance, cleaning, and upkeep of storm drain structures, streets, and parking areas will be developed and implemented by the Homeowners' Association (HOA). The landscape plan for the proposed project includes the planting of native species in the open space areas on the perimeter of the development. Landscaping that incorporates drought resistant plants can reduce irrigation and maintenance requirements. Native ...... PDF4-6 PDFS-1 species will be adapted to the climate and require little supplemental irrigation. Automatic rain gauges connected to irrigation controllers shall be installed and maintained by the HOA. These will monitor rainfal1 volume and interrupt watering schedules in response to site specific rainfall conditions. Rain gauges will be located adjacent to controllers to facilitate monitoring by maintenance personnel. Use of drip and efficient low-flow irrigation emitters to minimize irrigation requirements and over-irrigation. Structural Best Management Practices (BMPs) for the treatment of runoff prior to discharge to off-site locations will consist of a constructed wetlands composed of a series of three ponds for Areas Bl, B2, B3, and D; and catch basin inserts for Area A. F. Traffic and Circulation (1) Potential Impact: The Project has a Less Than Significant impact on short- term (construction) traffic impacts. Finding: The County hereby makes Finding 1 and detennines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: · This impact is considered to be Less Than Significant due to the time of day when most construction traffic occurs and he the relatively few trips anticipated to occur, as well as the fact that the project site is set in close proximity to designated truck routes. The implementation of the foUowing standard conditions will reduce this impact to Less Than Significant: SC 6-1 SC 6-2 Prior to the start of construction for each phase of development, the project developer shall submit a Construction Traffic Control PJan, to be prepared by a registered traffic engineer and submitted to the County of Orange for approval. Approval shall be required prior to issuance of grading permits. All traffic control work for construction shall conform to the latest editions of the State of California Department of Transportation Manual of Traffic Controls, Standard Plans, Standard Specifications, and Special Provisions. Notes indicating the need to obtain County approval of a construction traffic routing plan/construction access plan will be placed on the grading plan and included in the construction bid package. If determined necessary by the Manager, Development Services, PDSD, that a construction/grading haul road must be established, the project developer shall indicate this on all grading 35 plans. Further, the construction bid package shall also include the need for a construction/grading haul road. (2) Potential Impact: The Project has a Less Than Significant impact on transit service. Finding: The County finds that the Project has a Less Than Significant impact and that no mitigation measures, project design features or standard conditions are required or recommended. Facts in Support of Finding: Although the Project wilJ increase the demand locally and regionally for public transportation services, as part of the ongoing transportation planning process, OCT A will evaluate the feasibility of adding new lines to serve the Project site. Access to bus lines are currently available on Warner Avenue and PCH. Increased demand for transit service is seen as an adverse but not significant short-tenn impact. (3) Potential Impact: The Project has a Less Than Significant impact on bicycle trails. Finding: The County finds that the Project has a Less Than Significant impact and that no mitigation measures, project design features or standard conditions are required or recommended. Facts in Support of Finding: The Project does not remove any bicycle traiJs, but will add several new trails to the network. With the construction of these new trails, no significant adverse impact on bicycle facilities will occur. (4) Potential Impact: The Project has a Less Than Significant impact on Jong- tenn operation of study area intersections, with the exception of the intersection of PCH and Warner Avenue which is discussed below as Impact 6.1. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: With the exception of the intersection of PCH and Warner A venue, all study area intersections are forecasted to operate at satisfactory levels of service as a result of the implementation of the Areawide Traffic hnprovement Program (ATIP) improvements described in PDF 6-1. PDF6-1 ATIP Full Construction Components. Mitigation of off-site traffic impacts for the overall Bolsa Chica project have been identified in the Area Traffic bnprovement Program (ATIP) contained within certified FSEIR 551 (Orange County, 1996). The ATIP consists of improvements to be constructed and funded in phases as described below. 36 Location With issuance of the first to the 388th building pennits the project is required to include implementation of the following full construction ATIP components: Full Construction Improvements Pacific Coast Highway at East leg Warner A venue Warner A venue at Bo Isa Chica Street 1 PDF6-2 -Add 2nd left tum land -Add 3rd eastbound thru lane -Extend free right tum lane -The Pacific Coast Highway/Warner A venue improvements were completed in 1996 by Cal trans. East Leg -Add 2nd westbound left turn lane West Leg -Add 2nd eastbound left turn lane -With the reduced Upper Bench project, the additions of second eastbound and westbound left tum lanes at the Warner Avenue/Bolsa Chica Street intersection are no longer required for cumulative future conditions. ATIP Fair Share Components. The project's ATIP includes both the fuJJ construction components discussed above and the fair share components defined by the project's ultimate traffic contribution to cumulative roadway improvement requirements. Issuance of the first building permit of the site includes the project's participation in the following fair share improvements, displayed in the Table below. Table 4.6.D: ATIP Fair-Share Components Location uFair Share" Improvements FSEIRSSl Brightwate Project r Proposed Share of Project New Traffic Traffic2 Sbare3 Pacific Coast Complete the improvement of PCH to its 20% 3% 1 Not required under reduced development proposal (387 units). 2 Fair share percentages based on the previous 2,500 DU project development plan as shown on page 1-11 of the Bolsa Chica Mesa focused traffic study. 3 Project share was calculated using the ratio of the original 2,500 DU plan versus the current 388 DU plan. This ratio was then applied to the project share of new traffic taken from the original 2,500 DU plan. 37 Location "Fair Share" Improvements FSEIR551 Brightwate Project r Proposed Share of Project New Traffic Traffic2 Sbare3 Highway: full MPAH designation as a Primary (100 Golden West Street to foot ROW) north of Warner Avenue and Los Angeles County as a Major (120 foot ROW) south of Line Warner A venue Beach Boulevard at North Leg 30% 5% Warner A venue Add 4th southbound thru lane (this improvement is already in place) Magnolia Street at South Leg 12% 2% Warner A venue Add 3rd northbound thru lane East Leg Add 4th westbound thru lane West Leg Add 4th eastbound thru Jane Add 2nd eastbound left thru lane2 (5) Potential Impact: The proposed project will have a significant long-term adverse impact on traffic at the intersection of PCH and Warner Avenue. This intersection will experience a measurable traffic contribution (based on both County and City performance criteria) from the proposed project and is projected to operate at LOS F. Finding: The County makes Finding 3 that specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or alternatives identified in the final EIR. Fads in Support of Finding: Without ups1zmg PCH beyond its MP AH designation, a deficiency plan per the requirements of the Congestion Management Plan must be prepared. SC 6-3 requires the applicant to pay its pro rata fair share of preparing this plan. Beyond this contribution, however, no additional feasible mitigation measures have been identified at this location beyond the improvements that were completed during 1996 by Caltrans. This significant impact was previously acknowledged in FSEIR 551 (Orange County, 1996), in which the PCH!Wamer Avenue intersection was projected to experience unavoidable adverse impacts with its maximum feasible configuration. Because of the constraints posed by the wetlands at the intersection of Warner and PCH, Warner Avenue east of PCH cannot be improved to six Janes. The widening of Warner A venue would also require widening of the Outer Balsa Bay Bridge. Because of the presence of the wetlands adjacent to Warner, no feasible mitigation measures are availab]e for this intersection other than the improvements completed by Caltrans in 1996. The following SC is identified to require contribution to the preparation of a deficiency plan for this intersection: 38 SC6-3 G. Air Quality Without the upsizing of PCH beyond its MPAH designation, it will be necessary to develop a Deficiency PJan per the requirements of the Congestion Management Program (CMP). The CMP recognizes that not all projected roadway system deficiencies are avoidable through local actions and decisions. When a deficiency is identified, however, a jurisdiction must undertake specific actions if it is to comply with the CMP. In the case of state highways, the California Department of Transportation (Caltrans) has primary responsibility for preparing deficiency plans. The plan must identify the need for isolated location or an areawide deficiency plan, with areawide deficiency plans being the preferred approach. The applicant shall pay its pro rata fair share of preparing the deficiency p1an. (l) Potential Impact: The Project has a Less Than Significant impact as it pertains to local air quality impacts as measured by local CO hot spot analysis. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: A localized CO hot spot analysis was prepared for the Project. Modeling of the CO hot spot analysis was based on traffic volumes reflected in the proposed Project traffic study prepared by Urban Crossroads (2001). The impact of CO levels was analyzed using the Air Resources Board CALINE4 air quality model. The analysis indicated that neither state nor federal CO standards for one hour and eight hour durations would be exceeded at the nine intersections analyzed. Implementation of the project would not have a significant impact on local air quality and no nearby sensitive receptors would be affected by project-related local air quality impacts. Adherence to SC 7-4 will help improve traffic flow in the project vicinity and help reduce local air pollutants, including CO. SC7-4 The proposed project shall include pedestrian pathways, bus stops, and bikeways as required by adopted plane and programs in order to encourage alternate forms of transportation. The proposed project shall also incorporate measures to improve traffic flow. Measures to reduce traffic congestion and its associated air emissions consistent with the design of the AQMP will be incorporated into the project. These measures include methods of improving traffic flow and methods of stimulating alternative fonns of transportation (i.e., bicycle routes and bus turnout lanes). 39 (2) Potential Impact: The Project has a Less Than Significant impact with respect to its consistency with the adopted Air Quality Management Plan. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: The project was determined to be consistent with the AQMP with respect to the jobs/housing balance as it is consistent with regional growth projections. The project will also implement SCs which reduce traffic congestion and its associated air emissions consistent with the design of the AQMP. With the inclusion of these measures, the Project is considered to be in conformance with the AQMP. SC 7-4 The proposed project shall include pedestrian pathways, bus stops, and· bikeways as required by adopted plane and programs in order to encourage alternate forms of transportation. The proposed project shall also incorporate measures to improve traffic flow. Measures to reduce traffic congestion and its associated air emissions consistent with the design of the AQMP will be incorporated into the project. These measures include methods of improving traffic flow and methods of stimulating alternative fonns of transportation (i.e., bicycle routes and bus turnout lanes). (3) Potential Impact: The Project has a Less Than Significant impact with respect to the potential for the release of hazardous materials in ~gitive dust. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: Because much of the area to be developed has been used in the collection of crude oil, petroleum residue may be present in the soil and could be disturbed during grading operations. In order to minimize this potential impact, the Project will comply with SC 7-5 which requires a site assessment before any construction takes place, and the remediation of soils in areas where contamination has been identified. bnplementation of SC 7-3 will help reduce voe emissions associated with architectural coatings to below the SCAQMD emission threshold of 55 pounds per day of ROC/NOC and will be less than significant. SC 7-3 Precoated/natural colored building materials, water based or low voe coating, and utilization of coating transfer or spray equipment with high transfer efficiency shall be employed to reduce emissions associated with architectural coatings that 40 SC 7-5 contain VOCs. Furthermore, the project shall comply with SCAQMD Rule 1113, Architectural Coating, which restricts the amount of voe allowed in architectural coating to control voe emission in the Basin. In larger areas of both surface and subsurface contamination, a site assessment will be conducted before any construction takes place at that locale. (4) Potential Impact: Impact 7.1 Equipment Exhaust. The proposed Project will result in potentiaJly significant short-term construction related impacts from operation of construction equipment. Peak grading and construction emissions will exceed SCAQMD thresholds for the criteria pollutants NOx and PMlO. Finding: The County hereby makes Finding 1 that changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effect as identified in the final EIR. However, the County has determined that while the above-described impact can be partially mitigated by the mitigation measure identified below, this impact cannot be mitigated to a less than significant level. There are no other feasible mitigation measures or alternatives that would reduce this impact to an acceptable level. Therefore, the County hereby also makes Finding 3 which would require the adoption of a Statement of Overriding Considerations as a condition of project approval. Facts in Support of Finding: Grading and construction activities would cause combustion emissions from utility engines, heavy-duty construction vehicles, haul trucks and vehicles transporting the construction crew. Based on the methodology outlined in the SCAQMD CEQA Air Quality Handbook, construction emissions associated with grading of the Project, will exceed the SCAQMD daiJy thresholds for the cr:iter:ial poHutants of NOx and PMIO. Emissions of other criteria pollutants would be below the standards. Although the Project proposes implementation of the following standard conditions and mitigation measures, these measures are not sufficient to reduce the emissions to below a level of significance. Mitigation Measure 7.1: In order to reduce short-term construction impacts from emissions from equipment and vehicles, prior to issuance of grading pennits, the permit applicant shaJl include the following measures on construction plans to be monitored and reported by the contractor to the County on a monthly basis, to the satisfaction of the Director, PFRD: (a) Where feasible, the General Contractor shall time the construction activities so as not to interfere with peak hour traffic and minimize obstruction of through traffic lanes adjacent to the site; if necessary, a flag person shall be retained to maintain safety adjacent to existing roadways. 41 (b) The · General Contractor shall utilize electric or diesel powered equipment in lieu of gasoline powered engines where feasible. ( c) The General Contractor shall ensure that construction grading plans include a statement that work crews will shut off equipment when not in use. ( d) The Civil engineer shall include a statement on construction grading plans requiring that all construction equipment be tuned and maintained in accordance with the manufacturer's specifications. Mitigation Measure 7.3: . A construction and construction related activity monitor satisfactory to the Director, PFRD, shall be retained by the applicant prior to issuance of grading permit. The monitor shall monitor a11 activity on a daily basis, keep written daily record~, and file monthly activity reports with the Director, PFRD, for the duration of grading and infrastructure construction. The monitor shall be employed by the applicant or the applicant's contractor. The monitor shall report on the following strategies: (a) Construction equipment exhaust shall be minimized by use of; NOx control technologies, such as fuel injection timing retard for diesel engines and air to air after cooling. Low sulfur fuel (where available). Well maintained equipment and proper planning to mm1m1ze trips/use. Log fuel use, hours of operation, and periodic maintenance. (b) Fugitive dust shall be controlled as specified in Mitigation Measure 7.2 and SCAQMD rules and regulations. (c) Restrict delivery of construction supplies and off-site hauling of debris to non-peak . travel periods whenever feasible, except for concrete and earthwork related activities. (5) Potential Impact: Impact 7.2 Fugitive Dust. Fugitive dust em1ss1ons associated with demolition, land clearing, exposure, vehicle and equipment travel on unpaved roads, and cut and fill operations would exceed the SCAQMD threshold of 150 pounds per day. Nearby sensitive receptors and workers may be exposed to blowing dust. Finding: The County hereby makes Finding 1 that changes or alterations have been required in, or incorporated into, the project which avoid or substantially 42 lessen the significant environmental effect as identified in the final EIR. However, the County has determined that whi1e the above-described impact can be partially mitigated by the mitigation measure identified below, this impact cannot be mitigated to a less than significant level. There are no other feasible mitigation measures or alternatives that would reduce this impact to an acceptable level. Therefore, the County hereby also makes Finding 3 which would require the adoption of a Statement of Overriding Considerations as a condition of project approval. Facts in Support of Finding: Based upon estimates of project grading quantities on a daily basis, and the number of equipment used for grading, the FSEIR estimates that a total of 1,355 pounds of PMlO per day would be generated from soil disturbance without mitigation during peak grading/construction phase. This level of dust emission would exceed the SCAQMD threshold of 150 pounds per day. The project will be required as a Standard Condition (SC 7-1) to comply with SCAQMD Rules 403 and 402 concerning control of fugitive dust with best available control measures and implementation of dust suppression techniques to prevent fugitive dust from creating a nuisance off site. Although implementation of these standard conditions and mitigation measure 7.2 set forth below can reduce the fugitive dust generation by 50 to 75 percent, or approximately 338.8 . pounds per day, fugitive dust impacts would remain significant and adverse. SC 7-1 All required actions necessary to comply with SCAQMD Rule 402, which requires that there be no off-site dust impacts sufficient to cause a nuisance, and SCAQMD Rule 403, which restricts visible emissions from construction, shall be implemented as a part of the proposed project. Prior to the approval of a grading permit, the applicant shall demonstrate to the Manager, Subdivision and Grading, that such compliance will be achieved and that all such actions shall be listed on each grading plan under the General Notes Section. Additional dust suppression measures are included in the SCAQMD's CEQA Air Quality Handbook, are also included for implementation. Applicable Rule 403 measures: Apply nontoxic chemical soil stabilizers to manufacturers' specifications, to all inactive construction areas (previously graded areas inactive for ten days or more). Water active sites at least two times daily. (Locations where grading is to occur will be thoroughly watered prior to earth moving.) All trucks hauling dirt, sand, soil, or other loose materials are to be covered, or should maintain at least two feet of freeboard in accordance with the requirements of California 43 Vehicle Code (CVC) Section 23114 (freeboard means vertical space between the top of the load and top of the trailer). Pave construction access roads at least 100 feet onto the site from main road. Traffic speeds on all unpaved roads shall be reduced to 15 mph or less. Additional SCAQMD CEQA Air Quality Handbook Dust Measures: Revegetate disturbed areas as quickly as possible. All excavating and grading operations shall be suspended . :when wind. speeds (as instantaneous gusts) exceed 25 mph. All streets shall be swept once a day if visible soil materials are carried to adjacent streets (recommend water sweepers with reclaimed water). Install wheel washers where vehicles enter and exit unpaved roads onto paved roads, or wash trucks and any equipment leaving the site each trip. Implementation of these dust suppression techniques will reduce the fugitive dust generation (and thus the PMlO component) by 50 to 75 percent. Implementation of the following measures wilJ reduce short-term fugitive dust impacts on nearby sensitive receptors. Mitigation Measure 7.2: In order to reduce fugitive dust from construction activities, the following shall be implemented by the applicant. The applicant · shaJI furnish documentation to the satisfaction of the Director, PFRD, that the following provisions are included on the grading plans. During clearing, grading, earthmoving, excavation, or transportation of cut or fi1l materials, water trucks or sprinkler systems shall be used to prevent dust from leaving the site and to create a crust after each day's activities cease. During construction, water trucks or sprinkler systems shall be used 4 times a day to keep all areas of vehicle movement damp enough to prevent dust from leaving the site. At a minimum, this would include wetting down such areas in the later morning, watering during soil placement, after work is completed for the day, and whenever the wind exceeds 15 mph. 44 After excavation is completed, the entire area of disturbed soil shall be treated immediately with soil bonding agents until the area is landscaped, paved, or otherwise developed so that dust generation wj!J not occur. Soil stockpiled for more than two weeks shall be covered, kept moist, or treated with soil binders to prevent dust generation. Trucks transporting soil, sand, cut or fill materials and/or construction debris to or from the site shaJJ be tarped from the point of origin. Wash mud-covered tires and undercarriages of trucks leaving construction sites. Provide for street sweeping, as needed, on adjacent roadways to remove dirt dropped by construction vehicles or mud that would otherwise be carried off by trucks departing the project site. If dust is visibly generated that travels beyond the site boundaries, clearing, grading, earth moving, or excavation activities that are generating dust shall cease during periods of high winds (i.e., greater than 25 mph averaged over one hour) or during Stage 1 or Stage 2 episodes. (6) Potential Impact: Potential Impact: Impact 7.3 Area and Mobile Source Emissions. Emissions from on-site area sources alone would exceed the emission threshold for ROC established by the SCAQMD. Emissions from project-related mobile sources would exceed the operational thresholds for CO, ROC, and NOx established by the SCAQMD. Finding: The County hereby makes Finding 1 that changes or alterations have been required in, or incorporated into, the project which avoid or substantiaJiy lessen the significant environmental effect as identified in the final EIR. However, the County has determined that while the above-describ.ed impact can be partially mitigated by the mitigation measure identified below, this impact cannot be mitigated to a Jess than significant level. There are no other feasible mitigation measures or alternatives that would reduce this impact to an acceptable level. Therefore, the County hereby also makes Finding 3 which would require the adoption of a Statement of Overriding Considerations as a condition of project approval. Facts in Support of Findings: The proposed Project's 388 dwelling units will consume natural gas and have other on-site energy consumption emissions associated with fireplaces and consumer products as calculated by the URBEMIS7G model. These area sources will generate criteria pollutant emissions. Emissions from on-site area sources alone would exceed the emission threshold for ROC established b the SCAQMD. (See FSEIR at 4.7-23, Table 4.7.F.) In addition, the project will generate 4,656 daily vehicular trips. Based on the latest URBEMIS7G air quality model, emissions from project-related mobile sources (vehicle trips) wiJI exceed the thresholds for CO, ROC, and NOx 45 established by the SCAQMD. Emissions of PMI 0 would be below SCAQMD thresholds. SOx emissions are anticipated to be below the significance threshold as well. Although implementation of SC 7-2 and 7-4 would help reduce long- term operations emissions, the long-term operations emissions will remain significant and unavoidable. To the extent, there are remaining unmitigated impacts, the County has prepared a Statement of Overriding Considerations. SC7-2 SC7-4 H. Noise The project shall comply with Title 24 of the California Code of Regulations established by the Energy Commission regarding energy conservation standards. The proposed project shall include pedestrian pathways, bus stops, and bikeways as required by adopted plane and programs in order to encourage alternate forms of transportation. Th,e proposed project shall also incorporate measures to improve traffic flow. Measures to reduce traffic congestion and its associated air emissions consistent with the design of the AQMP will be incorporated into the project. These measures include methods of improving traffic flow and methods of stimulating alternative fonns of transportation (i.e., bicycle routes and bus turnout lanes). (1) Potential Impact: The proposed project has a Less Than Significant impact on short-term construction related noise impacts. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by compliance with standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: Short-term construction related impacts are generated by two sources. The first is the transport of workers and construction equipment/materials to the project site. Although there would be relatively high single event noise exposure potential from passing trucks which could cause possible short-tenn intermittent annoyances, the effect on long-term ambient noise levels would be less than significant, and is therefore considered a Less Than Significant effect of the project. The second type of short-term noise impact is noise related to excavation, grading and construction on the project site during the site preparation phase of the project. Although residences adjacent to the project site could potentially be exposed to construction noise Jevels exceeding 90 . dBA Lmax over a very short period of time when construction occurs near those residences, construction noise would be temporary, would occur only during daytime hours, would affect only the area directly adjacent to the active construction site, and would not occur on Sundays and holidays. Construction noise is regulated by the County's Noise Control Ordinance which establishes 46 hours during which construction activity can occur. Construction noise during the allowed construction time periods is exempt from the noise level provisions of the Noise ControJ Ordinance. Noise sources associated with construction is also exempt from the City's Noise Ordinance. The requirements of the City's Noise Ordinance are the same as the County's requirements. SC 8-2 requires cornpJiance with the County's Noise Ordinance and will reduce construction noise impacts to Less Than Significant. SC8-2 Construction Noise (Corresponding to County of Orange Standard Conditions of Approval N09) A Prior to the issuance of any grading permits, the project proponent shall produce evidence acceptable to the Manager, Building Pennit s Services, that: (1) All construction vehicles or equipment, fixed or mobile, operated within 1,000' of a dwelling shall be equipped with properly operating and maintained mufflers. (2) All operations shall comply with Orange County Codified Ordinance Division 6 (Noise Control). (3) Stockpiling and/or vehicle staging areas shall be located as far as practicable from dwellings. B. Notations in the above format, appropriately numbered and included with other notations on the front sheet of the project's permitted grading plans, will be considered as adequate evidence of compliance with this condition. (2) Potential Impact: The proposed project has a Less Than Significant impact on long-term on-site operational noise. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by compliance with standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: The proposed project includes residential uses and public open space uses. The proposed project includes 387 residences that are not anticipated to generate noise levels substantially different from the surrounding residential uses. The proposed project also includes parking areas for the park/open space areas. These uses are not anticipated to generate noise levels different of substantial1y greater than the ambient noise levels experienced in the vicinity of the project. Public park parking and street parking are exempted from the County's Noise Ordinance requirements. Compliance with SC 8-3 which establishes maximum on-site noise requirements will ensure compatibility with surrounding residential uses. 47 SCS-3 Consistent with County of Orange Codified Ordinance, Division 6 . (Noise Control) requirements, on-site noise shall not exceed 75 dBA for daytime and 70 dBA for nighttime at the adjacent property line . . (3) Potential Impact: The proposed project has a Less Than Significant impact on long-term off-site and on-site vehicular traffic noise. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by compliance with standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: The Federal Highway Administration traffic noise prediction model was used to evaluate highway traffic noise conditions in the vicinity of the project. Both future cumulative with and without project scenarios were analyzed. Noise levels at 50 :feet from the centerline of surface. streets in the area were modeled. Although there would be an increase in traffic noise levels on certain streets, such as Bolsa Chica Street, the noise level changes are due to area growth and planned development in the City of Huntington Beach. The project's contribution to future cumulative traffic noise levels is less than 3dBA, which is considered Less Than Significant. Therefore, the proposed project will have a Less Than Significant effect on traffic noise impacts to off-site sensitive uses. With respect to on-site traffic noise impacts, the portion of the project site that is adjacent to Los Patos Avenue and Bolsa Chica Street would not be exposed to traffic noise exceeding the 65 dBA CNEL noise standard. Although the area adjacent to Warner Avenue would be within the 65 dBA CNEL, there are no residential uses proposed within 250 feet of Warner Avenue that would be affected by or within the 65 dBA CNEL noise contour. Therefore , there are no significant Jong-term on-site traffic noise impacts. Compliance with SC 8-1 and 8-4 ensures that both on-site and off-site traffic noise impacts remain Less Than Significant. SC8-1 Residential Noise (Corresponding to County of Orange Standard Conditions of Approval NOI) The applicant shall sound attenuate all residential lots and dwellings against present and projected noise (which shall be the sum of all noise impacting the project) so that the composite interior standard of 45 dBA CNEL for habitable rooms and a source specific exterior standard of 65.dBA CNEL for outdoor living areas is not exceeded. The applicant shall provide a report prepared by a County-certified acoustical consultant, which demonstrates that these standards will be satisfied in a manner consistent with Zoning Code Section 7-9-137.5, as follows: 48 SC 8-4 A Prior to the recordation of a subdivision map or prior to the issuance of grading permits, as determined by the Manager, Building Permits Services, the applicant shall submit an acoustical analysis report to the Manager, Building Permits Services, for approval. The report shall describe in detail the exterior noise environment and preliminary mitigation measures. Acoustical design features to achieve interior noise standards may be included in the report in which case it may also satisfy "B" below. B. Prior to the issuance of any building permits for residential construction, the applicant shalJ submit an acoustical analysis report describing the acoustical design features of the structures required to satisfy the exterior and interior noise standards to the Manager, Building Permits Services, for approval along with satisfactory evidence which indicates that the sound attenuation measures specified in the approved acoustical report have been incorporated into the design of the project. C. Prior to the issuance of any building permits, the applicant shall show alJ freestanding acoustical barriers on the project's plot plan illustrating height, location and construction in a manner meeting the approval of the Manager, Building Permits Services. All construction shall comply with Title 24 Field Sound Transmission Class (FSTC) and Field Impact Insulation Class (FllC) standards. I. Biological Resources (I) Potential Impact: The proposed project has a Less Than Significant impact on terrestrial habitat. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: Although there will be a net loss of terrestrial habitat this is not a significant impact. The majority of the habitat impacted consists of 75.2 acres of ruderal and nonnative grasslands. Although 0.2 acres of coastal bluff scrub will be impacted, this is not considered significant because the area does not provide substantial habitat for any sensitive species on the project site. The larger, more welJ developed areas of coastal bluff scrub wi11 be preserved by the project. A small area (0.04 acre) of eucaplyptus will also be 49 impacted by grading. This is not considered significant because these trees are outside of the eucalyptus ESHA and does not support and its loss would not adversely affect raptors. The project proposes implementation of PDF 9-7 which proposes an increase in native plant species and provides benefits to vegetation. PDF 9-1 also ensures that construction activities will be monitored to avoid existing habitat areas proposed for preservation. PDF9-1 PDF9-7 Construction monitoring and maintenance requires a botanist to monitor all grading activities, conduct preconstruction meetings with construction contractors, provide on-site assistance to construction personnel, and stake out perimeters of existing habitats to be preserved. Submittal of a construction fencing and monitoring program and appropriately scaled maps prepared by the developer area required prior to issuance of grading permits. The construction fencing exhibits and monitoring program shall be reviewed and approved by the Director, PDSD prior to issuance of grading perinits. Fueling, maintenance, and spillage requirements and regular equipment inspection are also required. A construction fencing and monitoring exhibit will be submitted prior to the issuance of grading permits. The types and colors of appropriate markers will be identified in the exhibit. Planning Area 3A wi11 be revegetated with native plant species, and contain constructed wetlands to improve run off water quality. The area will function as a buffer between undisturbed areas adjacent to the site and the project residential development. The project applicant will consult with the Department of Fish and Game in the selection of plant species for the constructed wetland. Maintenance of the constructed wetland, by the Homeowners Association, other than routine items such as removal of debris or emergency repairs should be conducted between September 1 and February 28 to avoid bird breeding season. (2) Potential Impact: The proposed project has a Less Than Significant impact on wetlands, including the off-site lowland area. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: The on-site wetlands are not directly affected by the proposed project, but will receive project runoff through the constructed low flow treatment wetlands which will provide a continued water supply to the pocket wetlands area. The small seasonal wetland on the northern side of the project site will be avoided and the surrounding area protected from disturbance by establishment of a 100 foot buffer around the wetlands (except for the 50 southerly side which will have a 75 foot buffer). The off-site pocket lowland will receive large storm flows from the constructed treatment wetlands which may improve biological productivity of this area. No sensitive resources occur in this area. In order to ensure that the increase in the number of people introduced to the area, including the areas of environmental sensitivity, PDF 9-5 controls the unauthorized intrusion of people into the lowland area. PDF9-6 PDF9-7 The public access component of the proposed project will include 30 public parking spaces and a trail within PA 3A-l. The plan for PA 3A-l includes fencing and signage to deter the public from leaving designated trails. Planning Area 3A will be revegetated with native plant species, and contain constructed wetlands to improve run off water quality. The area will function as a buffer between undisturbed areas adjacent to the site and the project residential development. The project applicant will consult with the Department of Fish and Game in the selection of plant species for the constructed wetland. Maintenance of the constructed wetland by the Homeowners Association, other than routine items such as removal of debris or emergency repairs, should be conducted between September 1, and February 28 to avoid bird breeding season. In addition, the new PDF 5-1 from Section 4.5, Water Quality, provides for a low flow water quality treatment wetland adjacent to, and hydraulically connected to, the pocket wetlands at the southern edge of the project area. High flows would discharge into a constructed detention basing adjacent to the pocket wetlands and from there drain into the isolated pocket Lowland between the Bolsa Chica Mesa and EGGW ChaMel. The following SCs are brought forward from Section 4.5 (Water Quality) in this SEIR.. Very similar measures were included in Section 4. 7 (Marine/ Aquatic Biology) ofFSEIR 551 (Orange County, 1996). SC 5-1 Prior to the recordation of any final tract map, or issuance of grading pennits, as deemed appropriate by the Manager, Subdivision and Grading Services, the subdivider shall submit and obtain approval from the Manager, Subdivision and Grading, of a Water Quality Management Plan (WQMP) or Standard Urban Stonn Water Mitigation Plan (SUSMP), if applicable, specifically identifying Best Management Practices (BMPs) that will be used on site or off site to control predictable pollutant runoff. This WQMP or SUSMP shall identify, at a minimum, the routine, structural and nonstructural measures consistent with the County NPDES permit as it now exists, and any subsequent amendment finally adopted by the Regional Water Quality Control Board having jurisdiction that may be legally applied to the project, 51 SCS-2 which details implementation of BMPs whenever they are applicable to a project, the assignment of Jong-term maintenance responsibilities (specifying the developer, parcel owner, maintenance association, Jessee, etc.); and shall reference the location(s) of structural BMPs. Should the San Diego Regional Water Quality Control Board's tentative order 2001-193 be adopted, and prior to the full implementation of the Jurisdictional URMP required thereby, the project sha11 at a minimum implement the provisions and commitments of the proposed DAMP submitted in September, 2000 (corresponds to Draft County of Orange Standard Condition WQOI[August 16, 2001]). Prior to issuance of any grading permits, the applicant shall submit evidence to the Manager, Subdivision and Grading, that the applicant has obtained coverage under the NPDES statewide General Construction Activity Stormwater Permit from the State Water Resources Control Board (corresponds to County of Orange Standard Condition WQ04). (3) Potential Impact: The proposed project has a Less Than Significant impact on sensitive plant species. No federal or state threatened or endangered plant species occur in the project area so the project will have no impact on a listed plant species. Finding: The County hereby makes Finding 1 and detennines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: The proposed project could impact up to 12 percent of the southern tarplant community, which is a sensitive plant species. This impact is considered Less Than Significant because of the relatively small percentage of the overall population that will be affected and because PDF 9-2 requires replacement of the affected population. PDF9-2 The portions of the southern tarplant population that will be lost within the project area will be replaced on areas of the Bolsa Chica Mesa that will be preserved. Within the current project area, only a small portion of this population would be affected and would require replacement. A southern tarplant replacement program shall be prepared by the developer and submitted to the Director, PDSD for review and approval prior to issuance of grading pennits. The Director, PDSD shall submit the replacement program to the California Department of Fish and Game for review and comment prior to approval of the replacement program. ~2 Potential Impact: The proposed project has a Less Than Significant impact on invertebrates, amphibians, reptiles and mammals. Finding: This impact was detennined to be Less Than Significant and no mitigation measures were required. Facts in Support of Finding: The project will result in the loss of76.4 acres that provide invertebrate habitat. As the project site does not support unique invertebrate populations or sensitive invertebrate habitats, the overall impact to invertebrates is not ·considered significant. There are no sensitive amphibians or reptiles known to occur on the Project site. Although the project will result in the removal of upland habitat, this is not expected to affect the continued presence of the coyote at Bolsa Chica which plays an important role in controlling smaller, more destructive predators, such as the red fox. (4) Potential Impact: The proposed project has a Less Than Significant impact on upland birds. Finding: The County hereby makes Finding 1 and detennines that this potentia11y significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: The proposed project will result in the loss of approximately 89.3 acres of upland foraging habitat for raptors, primarily nonnative grasslands and disturbed upland areas. The elimination of this habitat may reduce the size of the wintering population of raptors, e.g., red tailed hawks, that utilize the project site, however, this is not considered a significant impact considering the subregional context. Even with the project, there will still remain substantial wintering habitat elsewhere in the region, and substantial foraging habitat remains in the Bolsa Chica area. The northern harrier and burrowing owl are ground-nesting species that could potentially occur on the project site; however. nesting has not been documented for either species and is not likely to occur. Both have been observed on the project site, however. Implementation of PDF 9-5 ensures that there will be no direct effect to the burrowing owl. PDF9-S Prior to the issuance of grading permits, and within 30 days of the beginning of construction, surveys shall be done according to the survey and mitigation program that has been developed by the California Burrowing Owl Consortium. If the survey results indicate that an active burrow is present within the project development area, the owls shall be passively relocated according to the consortium mitigation guidelines. Mitigation guidelines will be implemented under County oversight and in conjunction with the CDFG. Occupied burrows shall not be disturbed during the nesting season, from February 1 through August 31, unless the CDFG verifies that the birds have not begun egg-laying and 53 incubation or that the juveniles from those burrows are foraging independently and capable of independent survival at an earlier date. Alternative burrows shall be enhanced or created in pennanently preserved open space, at a ratio of 1: 1. A report indicating completion of the surveys and any necessary mitigation shall be provided to the County Environmental and Project Planning Division prior to the issuance of grading perinits. The burrowing owl relocation mitigation, if the bird is present and the mitigation is implemented, shall be implemented according t the California Burrowing Owl Consortium mitigation guidelines under County of Orange oversight and by coordination with the Department of Fish and Gaine. The responsible party to ensure compliance prior to issuance of grading permits is the Manager, County of Orange Environmental and Project Planning Division. (5) Potential Impact: The proposed project has a Less Than Significant impact on lowland birds and habitats. Finding: The County hereby makes Finding 1 and determines that this potentiaJiy significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: The proposed residential development will have the potential to introduce domestic animals, such as dogs and cats, into the project area which could potentially affect the adjacent lowlands, including restored habitat areas. Birds which nest on or near the ground, such as the Belding's savannah sparrow and western snowy plover could be subject to predation. PDF 9-3 wiJI provide a means to control the presence of domestic animals that can prey on these birds by preparation of a plan to control the presence of invasive and/or feral pets into wildlife areas. PDF 9-4 provides measures to reduce night lighting and light spillage into wildlife area which will also help protect the lowland habitat and species. PDF 9-3 PDF9-4 In conjunction with the County Animal Control, the applicant will devise and implement a plan to control the presence of invasive and/or feral pets in wildlife areas. Information on the detrimental effects of domestic cats on common and sensitive species of birds, as well as the hazards to domestic animals, shall be supplied to each homeowner who purchases property in the residential units. The plan is to be approved by the County Environmental and Project Planning Division prior to issuance of occupancy permits. Floodlamp shielding and/or sodium bulbs will be used in developed areas to reduce the amount of stray lighting into the wildlife areas. 54 be approved by the County Environmental and Project Planning Division prior to issuance of building pennits and shall include, at a minimum: • Methods for public education, including infonnation regarding invasive exotics that homeowners may not plant in their yards. • A landscape plan for common areas that avoids the use of invasive exotic species. • A list of invasive exotic species that will not be permitted in residential landscaping (lists A and B of the California Exotic Pest Plant Council's list of "Exotic Pest Plants of Greatest Ecological Concern in California as of October, 1999"). • A list of palms with persistent leaf bases that will not be permitted in residential Jandscaping. • An erosion control and storm runoff plan that shaJI be prepared prior to construction (see Section 4.5.3); if straw bales are used for erosion control, rice straw or equivalent weed free straw shall be used to prevent additional introduction of exotic species into native habitat. The portions of the southern tarplant population that will be lost within the project area will be replaced Qll areas of the Bolsa Chica Mesa that will be preserved. Within the current project area, only a small portion of this population would be affected and would require replacement. A southern tarplant replacement program shall be prepared by the developer and submitted to the Director, PDSD, for review and approval prior to issuance of grading permits. The Director, PDSD shall submit the replacement program to the California Department of Fish and Game for review and comment prior to approval of the replacement program. J. Aesthetics (1) Potential Impact: The proposed project has a Less Than Significant impact on short-term construction related visual and aesthetic impacts. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: During grading of the project site exposed pads and slopes will be visible to surrounding residents, motorists and recreational users. SC 10-3 ensures that the exposes areas are hydroseeded to minimize exposure of graded areas, and requires the screening of construction activities through the use of temporary fencing, landscaped berms, and/or landscaping. 56 SC 10-3 Prior to the issuance of any grading permit, the applicant shal1 provide evidence to Manager, Subdivision and Grading Services, that: a. Views of construction activities shall be shielded as feasible by measures that can include placement of temporary fencing, landscaped berms, and/or landscaping. b. All graded slopes shall be completely hydroseeded and/or landscaped within 90 days following completion of grading. (2) Potential Impact: The proposed project has a Less Than Significant impact on long-tenn impacts as it pertains to on-site visual elements as viewed from public viewsheds such as Pacific Coast Highway, the State Ecological Reserve and Los Patos A venue. Finding: The County hereby makes Finding l and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: Proposed development on the project site will alter the visual character of the area, and will be visible from different on-site and off- site viewsheds. The fonn, scale and massing of the structures provides consistency with that of existing residential development adjacent to the north of the project site. PDFs 10-1 and 10-4 further insures that structural impacts are minimized through incorporation of landscaping to minimize and naturalize the urban appearance. PDFl0-2 requires a landscape and hardscape design along Los Patos A venue to ensure a pleasing viewscape for pedestrian and motorists adjacent to the project site. The project also proposes "seaside" architecture to blend with the mature landscaping {see PDF 10-3). In order to minimize impacts from the State Ecological Reserve, SC 10-1 ensures that obtrusive light and glare from the project site is minimized through measures requiring the confinement of light rays to a specific location through the use of shorter light standards and directing lenses and/or shades. FinaJJy SC 10-2 requires that graded areas be compatible with the adjacent existing and proposed land uses and requires a landscaping plan for the area along Los Patos, as well as an urban edge treatment plan for development areas adjacent to the wetlands. PDF 10-1 A 100 foot wide buffer will be provided between the eucalyptus ESHA and the edge of residential development, and it will be landscaped primarily with native species within this recreation/open space corridor, on the southern perimeter of the project site. 57 PDF 10-2 A continuous and unbroken landscape lot will be provided along the entire length of Los Patos A venue to match the existing unbroken landscaped corridor and pedestrian walkway, which is part of the adjacent Sandover project southwest of the intersection of Bolsa Chica Street and Los Patos A venue. The vegetation will include trees, shrubs, and groundcover as well as a meandering sidewalk. PDF 10-3 The project's architectural design concept is an "American Seaside Village" theme, providing a mix of colors and textures, and including alternating roof fonns and pitches and variations in the design and scale of exterior elements. The project design will be characterized by unifying architectural integrity. PDF 10-4 The portions of the project site visible from publicly owned areas will be softened and extensively enhanced in rich native landscaping, incorporating the eucalyptus ESHA, and the freshwater ponds to be created on the project site's southern periphery, including the planting of coastal bluff scrub on the separator slope between the upper and lower mesas. SC 10-1 Prior to issuance of any building permits within tracts abutting wetlands, environmentally sensitive habitats, or the residential development setback area, the applicant shall demonstrate that alJ exterior lighting has been designed and located so that all direct rays are confined to the property in a manner meeting the approval of the Manager, Building Permit Services. SC 10-2 Prior to the issuance of each grading pennit or recordation of any applicable tract map, whichever happens first, the applicant shall provide the following plans subject to the approval of Manager, PFRD/HBP Program Management and Coordination, in consultation with the Manager, Environmental and Project Planning Division, which indicates that graded areas will be compatible with the adjacent existing and proposed land uses: a. A landscaping plan with setbacks a]ong Los Patos Avenue, including a landscaped parkway and community theme wall. b. An urban edge treatment plan for development areas adjacent to wetlands, which includes but is not limited to: building height and setback limits; landscape and fuel modification treatments; provisions for walls, fences, or berms; slope gradients and ratios, slope drainage structures, and architectural or landscape design themes. 58 (3) Potential Impact: Impact 10.1 Alteration of the Project Site from Public Viewsheds. Residential development wiU permanently alter the undeveloped appearance of the Bolsa Chica Mesa within the public viewsheds as seen from Pacific Coast Highway near Warner A venue and Pacific Coast Highway at the State Ecological Reserve Overlook, adjacent to Inner Bolsa Bay and along Los Patos A venue at Bolsa Chica Street. Finding: The County hereby makes Finding 1 that changes or alterations have been required in, or incorporated into, the project which avoid or substantially Jessen the significant environmental effect as identified in the final EIR through identification and implementation of project design features and standard conditions. However, the County has detennined that while the above-described impact can be partially mitigated by compliance with the project design features and standard conditions described above, this impact cannot be mitigated to a less than significant level. There are no other feasible mitigation measures or alternatives that would reduce this impact to an acceptable level. Therefore, the County hereby also makes Finding 3 which would require the adoption of a Statement of Overriding Considerations as a condition of project approval. Facts in Support of Findings: The only way to mitigate this impact to a level of Jess than significant is to prohibit the developer from developing the Project site. Although landscape design, landscaping, setbacks and other architectural elements reduce most of the visual impacts and provide for visual compatibility with surrounding areas, no effective measure is available to fully mitigate the loss of natural elements and undeveloped area that is currently within the public viewshed. This is particularly the case for the views from Los Patos A venue which is immediately adjacent to the project site. The remaining two public viewsheds are both from Pacific Coast Highway which is over a mile away from the proposed development and views from those vantage points will be mitigated through the landscaping, setbacks and architectural elements of the project. To the extent, there are remaining unmitigated impacts, the County has prepared a Statement of Overriding Considerations. K. Cultural Resources (1) Potential Impact: The proposed project has a Less Than Significant impact on ORA-83, a "historical resource" as defined in CEQA Guidelines Section 15064.5. Finding: The County hereby makes Finding 1 and detennines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: There are six recorded archaeological sites either on or adjacent to the project site, some of which also contain historical components. Two of these sites, ORA-86 and ORA-144, are not located on the 59 project site and wi1l not be impacted by development. Two sites, ORA-84 and ORA-288 are both considered to be "destroyed" by prior site disturbance. Data recovery work has been completed for ORA-85. Only one archaeological resource for which data recovery programs has not been completed will be affected by project implementation. That site is ORA-83 which has been determined to be eligible for listing on the National Register of Historic Places and is considered a "historical resource" as that term is defined in CEQA Guidelines Section 15064.5 Implementation of the proposed project wiU result in impacts to this archaeological site through development of the site for residential uses. Implementation of the following project design features and standard conditions wiJI ensure that project impacts to ORA-83 will not create a significant impact. These measures include implementation and completion of a data recovery program and controlled grading operations consistent with an issued coastal development permit for archaeological resource excavations. PDF 11-1 requires completion of a research design to guide the analysis of cultural materials recovered through the data recovery and construction monitoring work. PDF 11-2 requires implementation of the data recovery program as overseen by a team of peer reviewers and qualified Native American monitors. PDF 11-3, 11-4 and SC 11-1 require that the project archaeoJogist conduct a controlled grading program prior to site grading for development and establish procedures for archaeological resource surveillance prior to site grading. Because Native American human remains have been recovered on this site, PDF 11-5 requires compliance with an existing reburial agreement. In conclusion, with implementation of all of these measures, the impacts to archaeologicaJ resources are detennined to be reduced to a level of Less Than Significant. PDF 11-1 PDF 11-2 The research design for recovered material analysis for the Bolsa Chica Region currently in preparation shall be completed. The research design shall contain a discussion of important research topics for recovered material analysis that can be addressed employing data from the Bolsa Chica sites. The research design shall be reviewed by at Jeast three qualified archaeologists as required by the California Coastal Commission Guidelines. A data recovery program shall be implemented and completed for important or unique archaeological resources in areas proposed for urban development on Bo1sa Chica Mesa and for proposed urban development and wetJands restoration. The scope of work for the data recovery excavations shall be determined by the project archaeologist and reviewed and approved by the three qualified peer reviewer archaeologists established pursuant to CCC permit conditions. The data recovery excavations shalJ be completed prior to issuance of a grading permit and shall be monitored by a qualified Native American. The data recovery program shall be considered complete when the peer review group concludes that the data recovery excavations have been completed in accordance with its approved scope of work. Once data recovery excavations 60 have been completed, a report of the data recovery program shall be prepared by the project archaeologist and reviewed by the peer review team, and submitted to appropriate governmental and academic institutions. Data recovery investigations. testing, analysis, arid reports shall be completed at the Applicant's expense. PDF 11-3 For ORA-83, prior to any grading activity at this site, a controlled grading program shall be conducted by the project archaeologist in the field area to recover any cogged stones or other important artifacts that may remain in this disturbed portion of the site. The controlled grading program shall be monitored by a qualified Native American. PDF 11-4 In addition to compliance with the standard condition set forth below, which requires that a County certified archaeologist be retained to establish procedures for archaeological resource surveillance prior to grading and to monitor grading within 500 feet of all recorded archaeological sites, the project applicant shall also retain a qualified Native American to monitor all grading activities monitored by the County certified archaeologist on Bolsa Chica Mesa. PDF 11-5 A reburial agreement has been executed between the project applicant and the Juaneno Band of Mission Indians regarding the treatment and disposition of prehistoric Native American human remains discovered at ORA-83, and recommendations on the treatment and disposition of the human remains have been obtained from the other most likely descendants. If any additional prehistoric human remains are discovered on the Bolsa Chica Mesa, this agreement shal1 be extended to cover the treatment and disposition of those remains. SC 11-1 Prior to the issuance of any grading permit, the applicant shall provide written evidence to the Manager, Subdivision and Grading, that applicant has retained a County certified archaeologist, to observe grading activities and salvage and catalog archaeological resources as necessary. The archaeologist shall be present at the pregrade conference, sha11 establish procedures for archaeological resource surveil1ance, and shaJI establish, in cooperation with the applicant, procedures for temporarily halting or redirecting work to permit the sampling, identification, and evaluation of the artifacts as appropriate. If the archaeological resources are found to be significant, the archaeological observer shall determine appropriate actions, in cooperation with the project applicant, for exploration and/or salvage. ~1 Prior to the release of the grading bond, the applicant shaJJ obtain approval of the archaeologist's follow-up report from the Manager, HBP/CoastaJ and Historical Facilities. The report shall include the period of inspection, an analysis of any artifacts found, and the present repository of the artifacts. Applicant shall prepare excavated material to the point of identification. Applicant shall offer excavated finds for curatorial purposes to the County of Orange, or its designee, on a first refusal basis. These actions, as well as final mitigation and disposition of the resources, shall be subject to the approval of the Manager, HBP/Coastal and Historical Facilities. Applicant shall pay curatorial fees if an applicable fee program has been adopted by the Board of Supervisors, and such fee program is in effect at the time of presentation of the materials to the County of Orange or its designee, all in a manner meeting the approval of the Manager, HBP/Coastal and Historical Facilities. L. Paleontological Resources (1) Potential Impact: The proposed project has a Less Than Significant impact on paleontological resources. Finding: The County hereby makes Finding l and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: To date, no paleontological resources have been recorded on the project site, however, important resources such as main terraces and Quaternary deposits have been identified in nearby areas, therefore grading operations have the potential to disturb paleontological resources. Compliance with the County's standard conditions identified below ensures that prior to grading activities, a qualified paleontologist has been retained to conduct a literature review and field survey, a pre-grade salvage operation, and to monitor grading operations. Compliance with these measures will reduce this potentially impact to Less Than Significant. SC 12-1 Prior to the issuance of any grading permit, the applicant shall obtain approval from the Manager, HBP/Coastal and Historical Facilities of a report on a literature and records search and field survey of the project site. The applicant shalJ retain a County- certified paleontologist to complete the literature and records search for recorded sites and previous surveys. The paleontologist shall conduct a field survey unless the entire proposed project site has been documented as previously surveyed in a manner which meets the approval of the Manager, HBP/Coastal and Historical Facilities. The applicant shall implement the mitigation measures 62 SC 12-2 SC 12-3 in the report in a manner meeting the approval of the Manager, HBP/Coastal and Historical Facilities. This SC corresponds to County of Orange Standard Condition A05 (County of Orange, 2000). Prior to the issuance of any grading permit, the project applicant shall obtain approval from Manager, HBP/Coasta) and Historical Facilities of a report of the pre-grade paleontological salvage operation. The applicant shall . retain a County-certified paleontologist to conduct pre-grade salvage excavation and prepare a report of the exposed resources. The report shall include methodology, an analysis of artifacts found, a catalogue of artifacts, and their present repository. Applicant shall prepare excavated materials to the point of identification. The applicant shall offer· excavated finds for curatorial purposes t~ .the C:qunty of Orange, or its designee, on a first refusal basis. --Applicant shall pay curatorial fees if an applicable fee program has been adopted by the Board of Supervisors, and such fee program is in effect at the time of presentation of the materials to the County of Orange or its designee, all in a manner meeting the approval of the Manager, HBP/Coastal and Historical Facilities. This SC corresponds to County of Orange Standard Condition ·A06 (County of Orange, 2000). Prior to the issuance of any grading permit, the project applicant shall provide written evidence to the Manager, Subdivision and Grading, that applicant has retained a County certified paleontologist to observe grading activities and salvage and catalogue fossils as necessary. The paleontologist shall be present at the pre-grade conference, shall establish procedures for paleontological resource surveillance, and shall establish, in cooperation with the applicant, procedures for temporarily halting or redirecting work to permit sampling, identification, and evaluation of the fossils. If the paleontological resources are found to be significant, the paleontologist shall detennine appropriate actions, in cooperation with the applicant, which ensure proper exploration and/or salvage. Prior to the release of the grading bond the applicant shall submit the paleontologist's follow up report for approval by the Manager, HBP/Coastal and Historical Facilities. The report shall include the period of inspection, a catalogue and analysis of the fossils found, and the present repository of the fossils. Applicant shall prepare excavated material to the point of identification. The applicant shall offer excavated finds for curatorial purposes to the County of 63 M. Recreation Orange, or its designee, on a first refusal basis. These actions, as well as final mitigation and disposition of the resources, shall be subject to approval by the HBP/Coastal and Historical Facilities. Applicant shaJI pay curatorial fees if an applicable fee program has been adopted by the Board of Supervisors, and such fee program is in effect at the time of presentation of the materials to the County of Orange or its designee, all in a manner meeting the approval of the Manager, HBP/Coastal and Historical Facilities. This SC corresponds to County of Orange Standard Condition A07 (County of Orange, 2000). (1) Potential Impact: The proposed project has a Less Than Significant impact on local park requirements. Finding: The County determines that this potentially significant impact is Less · Than Significant and that no project design features, standard conditions of approval, or mitigation measures were required or recommended. Facts in Support of Finding: The County Local Park Code requirement for the proposed project is approximately 2. 7 net acres of local parks. The proposed project provides 3.3 net acres of private, usable park land. Since this is private land, part of' the publicly accessible open space in PlaJUling Area 3A-l will also be applied to meet local park requirements. The park requirements of the City of Huntington Beach will be satisfied through the payment of in lieu fees since the project only generates approximately 25 new residents in the City. (2) Potential Impact: The proposed project has a Less Than Significant impact on County of City regional recreation areas or facilities. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: As a result of new residents from the proposed project, Bo1sa Chica State Beach could experience greater use, however, this increased use is considered insignificant in light of the amount of available beach space at Bolsa Chica State Beach and surrounding beaches. Future residents can also be expected to use the Harriett Weider Regional Park, however, the project provides substantial additional passive and active recreational acreage, including dedication of additional land to the Regional Park. Finally, while privately owned and maintained, the project provides new facilities that are not available today and public access to open space areas not currently accessible today. Implementation of PDFs 13-1 and 13-2, and SCs 13-1 and 13-2 ensure that this potential impact is reduced to Less Than Significant. 64 PDF 13-1 PDF 13-2 SC 13-1 SC 13-2 Planning Area 3A-1 on the perimeter of the Brightwater project is a 23 acre passive recreational area containing open space, pedestrian trails and 30 public parking spaces. Development Area 7-1 (2.5 acres) will have a private recreation center composed of swimming pools, and community park built by the applicant and maintained by the Homeowners Association. A. Prior to the recordation of an applicable subdivision map that creates building sites, the subdivider shall make an irrevocable offer to dedicate an easement over Lot(s) AC, AE, Z for private local park purposes to the County of Orange in a form approved by the Manager, Real Property, in consultation with the Manager, Current Planning Services. The subdivider shall not grant any other easement over the private park easement that is inconsistent with the local park uses, unless that easement is made subordinate to said local park easement in a manner meeting the approval of the Manager, Real Property in consultation with the Manager, Current Planning Services. B. Prior to recordation of an applicable final subdivision map, the subdivider shall submit a preliminary concept plan of the proposed private recreation facilities to the Manager, Current Planning Services, for review and approval. Prior to the issuance of a grading permit, the applicant shaJl submit an irrevocable offer of dedication to the Manager HB&P for land within the Harriet Wieder Regional Park. (3) Potential Impact: The proposed project has a Less Than Significant impact on County or City trail plans, parks and recreational facilities. Finding: The County determines that this potentially significant impact is Less Than Significant and that no project design features, standard conditions of approval, or mitigation measures were required or recommended. Facts in Support of Finding: The project will construct Class II bike lanes within the project site which will connect with existing Class II trails along Warner Avenue and Bolsa Chica Street. A possible future connection to the proposed regional bike trail planned to parallel the EGGW Flood Control Channel will be detennined when that trail alignment is established. Since future bike trails will c01mect to existing Class II trails on the County and City General Plans, and wilJ not result in modification of those trails or adversely impact continued use and development of the trail system, the project is consistent with the General Plan and has no impact on trails, parks or recreational facilities. 65 N. Hazards and Hazardous Substances (1) Potential Impact: The proposed project has a Less Than Significant impact on creating a substantial risk of an explosion or a fire that poses a substantial threat to human safety. Finding: The County hereby makes Finding I and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions. Facts in Support of Finding: Although· the project site current contains petroleum facilities that are no longer in active use, once the site is developed, aJl of the identified and any additional hazardous substances and/or petroleum facilities that are encountered will be removed pursuant to PDF 14-1. The proposed project is a residential development that will not store large quantities of flammable or explosive materials. Although the site is in a wildland fire risk area, the landscaping plan for the project calls for the removal of nonnative vegetation. SC 14-2 address the need for fuel modification for the project. Finally, the 14 inch Southern California Edison gas line that extends from the Bolsa Chica Street/Los Patos intersection onto the future extension of Bolsa Chica Street onto the project site will be relocated from its current depth of three feet below ground surface to a depth of ten feet below ground surface. This relocation will be undertaken by SCE. PDF 14-1 SC 14-2 A Grading Mitigation Plan will be developed by the applicant for each area prior to initiation of grading activities. The Grading Mitigation Plan will include the locations of all on-site abandoned oil wells and pipelines. The Grading Mitigation Plan will include a pJan for remediation if contaminated soil is encountered during the grading or site development activities. The Grading Mitigation Plan wiIJ also provide details of the steps to be taken if unexpected conditions are encountered during grading or site development, such as additional pipelines or abandoned weJls. A fuel modification plan will be developed in accordance with the Orange County Fire Authority (OCF A) requirements. (2) Potential Impact: The proposed project has a Less Than Significant impact on creating a substantial risk of the release of hazardous substances or petroleum products that would cause significant degradation of the environment. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions Facts in Support of Findings: The findings of the phase II environmental site assessment concluded that on-site areas of concern identified in previous environmental assessments were determined not to pose a significant threat to the 66 envirorunent and no further action was required. PDF 14-1 requires implementation of the Grading Mitigation Plan developed for the site that identifies the plan for cleaning up contamination in the event contaminated soils are encountered during grading. The potential for hazardous spills during construction will be addressed through preparation of and compliance with a Stormwater Pollution Prevention Plan and applicable best management practices. The implementation of PDF 14-1, SC 5-2, SC 14-1 and SC 14-3 address the potential for hazardous substances release and minimize this impact to a level of Less Than Significant. PDF 14-1 SC 14-1 SC 14-3 SC 5-2 A Grading Mitigation Plan will be developed by the applicant for each area prior to initiation of grading activities. The Grading Mitigation Plan will include the locations of all on-site abandoned oil welJs and pipelines. The Grading Mitigation Plan will include a plan for remediation if contaminated soil is encountered during the grading or site development activities. The Grading Mitigation Plan will also provide details of the steps to be taken if unexpected conditions are encountered during grading or site development, such as additional pipelines or abandoned wells. Consultation with local and/or State regulatory agencies will be conducted if .oil facilities or contaminated soils are encountered during project grading activities (refer to PDF 14-1). The two abandoned oil wells located within the residential development (Figure 4.14.1) will be reabandoned in accordance with established State Division of Oil, Gas, and Geothermal Resources (DOGGR), and OCF A standards. Any wells located beneath a dwelling or within ten feet of a dwelling will be vented in accordance with DOGGR and OCFA standards. Prior to issuance of any grading pennits, the applicant shall submit evidence to the Manager, Subdivision and Grading, that the applicant has obtained coverage under the NPDES statewide General Construction Activity Stonnwater Permit from the State Water Resources Control Board (corresponds to County of Orange Standard Condition WQ04). (3) Potential Impact: The proposed project has a Less Than Significant impact on creating a substantial threat to human health through exposure of the public to hazardous substances or petroleum products. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions 67 Facts in Support of Findings: PDF 14-1 and SC 14-1 provide measures to prevent exposure to hazardous substances and petroleum products and procedures to follow in case these items are encountered during grading. The proposed project does not provide a significant new source of hazardous substances and petroleum products use, storage or disposal. PDF 5-4 describes the proposed public awareness program for future homeowners which includes the proper use and disposal of household hazardous wastes, such as pesticides and fertilizers . . Implementation of these measures reduces this impact to Less Than Significant. PDF 14-1 SC 14-1 PDFS-4 A Grading Mitigation Plan will be developed by the applicant for each area prior to initiation of grading activities. The Grading Mitigation Plan will include the locations of all on-site abandoned oil wells and pipelines. The Grading Mitigation Plan wiJI include a plan for remediation if contaminated soil is encountered during the grading or site development activities. The Grading Mitigation Plan will also provide details of the steps to be taken if unexpected conditions are encountered during grading or site development, such as additional pipelines or abandoned wells. Consultation with local and/or State regulatory agencies will be conducted if oil facilities or contaminated soils are encountered during project grading activities (refer to PDF 14-1 ). A public awareness program will be developed concerning water quality for future homeowners. The program will emphasize the proper use of irrigation, fertilizers, and pesticides by homeowners and landscape contractors. The program will be implemented by the HOA, as outlined in the WQMP. O. Public Services and Utilities (l) Potential Impact: The proposed project has a Less Than Significant impact on police services. Finding: The County determines that this potentially significant impact is Less Than Significant and that no project design features, standard conditions of approval, or mitigation measures were required or recommended. Facts in Support of Finding: Implementation of the project poses no impact on police services. The Orange County Sheriff-Coroner can serve the project site from units assigned to Sunset Beach with back ups from Rossmoor, Midway City and the Stanton Substation. The response times can alJ be met by Sheriff patrol in the area. The City portion of the site can be served from the City Police Department from its central facility. As such, the project does not have a significant impact on police services. (2) Potential Impact: The proposed project has a Less Than Significant impact on fire protection within the City of Huntington Beach. 68 Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of. approval. No mitigation measures were required or recommended. Facts in Support of Finding: Standard response times for the City can be met in providing fire protection for the City portion of the proposed project. PDF 15-2 requires the installation of fire sprinklers within the residential units. PDF 15-3 requires implementation of a fuel modification plan which minimizes the risk of wildJand fires. SC 15-1 through SC 15-5 provide detai1ed on-site requirements to ensure that fire protection services can be effectively provided. PDFIS-2 PDF 15-3 SC 15-1 SC 15-2 Fire sprinklers wi11 be instaJled in each habitable structure within the proposed project.

Provisions shall be made by the applicant for the repair and maintenance of the system, in a manner meeting the approval of the Fire Chief. Prior to the issuance of any certificate of use and occupancy, all fire hydrants shall have a blue reflective pavement marker indicating the fire hydrant location on the street or drive per the Orange County Fire Authority Standard, as approved by the Fire Chief. These markers are to be maintained in good condition by the property owner. Water Availability (note: This SC corresponds to the County qf Orange Standard Condition FP02 [County of Orange, 2000]). 69 SC 15-3 SC 15-4 Prior to the issuance of a building permit, the applicant shall provide evidence of adequate fire flow. The Orange County Fire Authority Water Availability for Fire Protection form shall be signed by the applicable water district and submitted for approval . to the Orange County Fire Authority. If sufficient water to meet fire flow requirements is not available, an automatic fire extinguishing system may be required in each structure affected by the insufficient fire flow. Fire Access Roads (note: This SC corresponds to County of Orange Standard Condition FP04 [County of Orange, 2000]). Prior to recordation of a subdivision map, the applicant shall obtain approval of the Fire Chief for all fire protection access easements and shall dedicate them to the County. Prior to issuance of any grading permits, the applicant shall submit and obtain approval of plans for all roads, streets and courts, public or private, from the Fire Chief in consultation with the Manager, Subdivision and Grading Services. The plans shall include the plan view and sectional view, and shall indicate the grade and width of the street or court measured flow line to flow line. All proposed fire apparatus turnarounds shall be clearly marked when a dead-end street exceeds 150 feet or when otheiwise required. Applicable CC&Rs, or other approved documents, shall contain provisions that prohibit obstructions such as speed bumps/humps, control gates, or other modifications within said easement without prior approval of the Fire Chief. A note shall be placed on the fire protection access easement p1an indicating that all street/road signs shall be designed and maintained to be either internally or extema11y ilJuminated in a manner meeting the approval of the Fire Chief.

Said agreement shall be accompanied by financial security. (3) Potential Impact: The proposed project has a Less Than Significant impact on energy. Finding: The County hereby makes Finding 1 and determines that this potentially significant impact is Less Than Significant by the implementation of project design features and standard conditions of approval. No mitigation measures were required or recommended. Facts in Support of Finding: The proposed project's average annual consumption of electrical energy is 2,177,456 KWh per year. Although California has recently experienced a disruption in its electrical energy supply as a result of the restructuring of the utility industry, the actual national and regional supply of energy is not at issue. Rather, the issue is one of supply and demand economics and the current strategy of purchasing long-term contracts for power. The energy "crisis" experienced in winter 2000 has changed recently due to long- term contracts ensuring a more constant supply of electricity, successful conservation programs and conservation at the household level. In addition, the State is also initiating a number steps to avert a future crisis, including accelerating the approval and licensing of additional in-state power plants. The relative impact of the project on regional electrical energy supplies will remain below the level of significance regardless of the cost of electrical energy. The project's demand on natural gas supplies can be provided by the extension of existing facilities in the area to the project site, thus the project's impact on natural gas in not considered significant. PDF 15-1 requires incorporation of energy-saving measures for energy and water conservation. PDF 15-1 Application of Title 24 of the California Code of Regulations wilJ ensure the use of design standards that wi11 maximize conservation of energy and water resources. 71 (4) Potential Impact: The proposed project has a Less Than Significant impact on schools. Finding: The County determines that this potentially significant impact is Less Than Significant and that no project design features, standard conditions of approval, or mitigation measures were required or recommended. Facts in Support of Finding: The project will generate approximately 77 students for the Huntington Beach Union High School District and 155 students for the Ocean View School District. State legislation establishes the maximum statutory development fee that can be assessed by school districts on new development to offset the project's impacts on school facilities. In letters from the Huntington Beach Union High Schoo] District, the District indicated that these fees will address the needs generated by the project. The Ocean View School District has identified additional facility needs including a new portable classroom at Mesa View Middle School and a new elementary school to accommodate the students generated by. the project. However, as with the High School District, statutory fee ]imitations establish the maximum amount of fees assessed on new development. Although Ocean View School District has identified capacity needs, the District also has a number of facilities that are currently being leased or otherwise used for non-teaching purposes. If consideration were given to utilizing the District's existing facilities, student generation from the project could be accommodated without constructing new facilities. Because the elementary and middle schoo] needs can be accommodated through use of existing facilities, and/or through the application of the State-mandated school fees to address feasibility needs, this impact was determined to be less than significant. (5) Potential Impact: The proposed project has a Less Than Significant impact on water and wastewater impacts. Finding: The County detennines that this potentiaJly significant impact is Less Than Significant and that no project design features, standard conditions of approval, or mitigation measures were required or recommended. Facts in Support of Finding: The Southern California Water System will own, operate and maintain the entire domestic water distribution system for the project. The estimated water use for the project is 200,880 gallons per day. Domestic water for the project wilJ be stored in an underground, 2 million gallon reservoir that will be constructed as part of the project. The sews has indicated that it has sufficient supplies to meet the project's need for potable water. Therefore, this impact is Less Than Significant. The landowner will construct all of the on-site wastewater facilities, and once constructed, the facilities will be owned, operated and maintained by sews. Wastewater wiJI flow into existing trunk sewer lines in Los Patos Avenue. The project site also includes a 15 inch sewer feed line into an existing 21 inch trunk sewer in Bolsa Chica Street. The project will be annexed into the County 72 Sanitation District of Orange County which has indicated that its facilities have the capacity to service the project. (6) Potential Impact: The proposed project has a Less Than Significant impact on solid waste refuse disposal capacity. Finding: The County detennines that this potentially significant impact is Less Than Significant and that no project design features, standard conditions of approval, or mitigation measures were required or recommended. Facts in Support of Finding: The project waste generation is estimated to be 20,646 pounds per day. With State-mandated recycling programs, approximately 11,383 pounds of solid waste per day would be disposed of at area landfills. The County of Orange owns and operates three active landfills. The Linda Alpha Landfill is the facility closest to the project and will likely be the receiving waste facility. The Orange County landfill system has capacity in excess of IS years, and therefore, it may ·be assumed that adequate capacity for the project is available for the foreseeable future. (7) Potential Impact: The proposed project has a Less Than Significant impact on telephone and cable service. Finding: The County detennines that this potentially significant impact is Less Than Significant and that no project design features, standard conditions of approval, or mitigation measures were required or recommended. Facts in Support of Finding: Verizon Telephone Company and Time Warner Cable have indicated that service for the project can be provided with no significant adverse impact to their systems. (8) Potential Impact: Impact 15-1 Emergency Medical and Fire Services. The nearest paramedic van is located at Station 48 in Seal Beach, and from that station, the paramedic response time to the Project site is 15 minutes. Although the nearest fire station is located in Sunset Beach, the County Fire Authority estimates that standard response times may be exceeded. Implementation of the project will result in emergencies and fire service needs that are beyond the current response capabilities of the Orange County Fire Authority. Finding: The County hereby makes Finding 1 and detennines that this potentia11y significant impact is Less Than Significant through implementation of the project design features, standard conditions of approval, and mitigation measures described below. Facts in Support of Finding: The potentially significant impacts regarding fire and emergency medical services can be reduced to a level of Less Than Significant by implementation of the fo11owing project design features, standard conditions and mitigation measures. 73 PDF 15-2 requires the installation of fire sprinklers within the residential units. PDF 15-3 requires implementation of a fuel modification plan which minimizes the risk of wildland fires. SC 15-1 through SC 15-5 provide detailed on-site requirements to ensure that fire protection services can be effectively provided. PDF 15-2 PDF lS-3 SC 15-1 SC 15-2 Fire sprinklers will be installed in each habitable structure within the proposed project. A fuel modification plan shall be implemented for that portion of the project adjacent to natural open spaces which present a wildland fire risk. Such plan shall be developed by the developer and submitted for review and approval by the Orange County Fire Authority prior to issuance of building permits. The plan shall be implemented prior to issuance of occupancy permits. Fire Hydrants (note: Tfil.s SC corresponds to County of Orange Standard Condition FPOl [County of Orange, 2000]). · Prior to the issuance of any grading permit, the applicant shall submit a fire hydrant location plan for review and approval of the Fire Chief.

The applicant shall design, build, equip, and otherwise fund new fire service facilities and equipment to serve this project in an amount determined by OCFA. . 6. FINDINGS REGARDING ALTERNATIVES The FSEIR identified seven alternatives as follows: (1) Biodiversity Park Alternative (2) No Project/Existing General Plan Alternative (3) No Project/No Development Alternative (4) Alternative Site Alternative (5) Very Low Density Residential Alternative (6) Proposed Project with Perimeter Road Alternative (7) Drainage Design Alternative The County's findings and facts in support of findings with respect to each of the alternatives considered are provided below: 1. Biodiversity Park Alternative Description: This alternative proposes that the entire Bolsa Chica property be used for conservation purposes, with passive recreation uses, native habitat restoration, and environmental education opportunities. The project site would be designated as a conservation area under this alternative and would be the subject of a comprehensive native habitat restoration 76 program subject to funding availability. The upland habitat restoration areas would include native grasslands, coastal bluff scrub communities, and dune scrub communities. . Environmental Effects: This alternative would result in minimal environmental impacts and some environmental benefits. This alternative would create a significant impact with respect to traffic but this impact can be mitigated to a level of insignificance. It should be noted, however, that even under this alternative, the intersection at Warner Avenue and Pacific Coast Highway is projected to operate at unacceptable LOS conditions in the future and no feasible mitigation measures have been identified to aJleviate that condition. There would be some impacts to the topography and on short-tenn erosion and shorMerm air quality due to the grading required for ingress and egress and the minor development of structures. This alternative would avoid or substantiaJly reduce the following impacts of the project: • The intersection of PCH and Warner, which is subject to significant and unavoidable impacts even without the project, would remain impacted but this alternative would contribute fewer vehicle trips to this intersection than the proposed project. • Long term cumulative air quality impacts due to vehicle emissions would be reduced to Jess than significant levels. • Cumulative emissions of NOx, ozone, CO would be reduced to less than significant levels. • Changes to the viewshed of Balsa Chica Mesa from PCH in the vicinity of Warner Avenue and changes to the viewshed from Los Patos Avenue would be avoided. Ability to Achieve Project Objectives: This alternative would not meet the project objectives relating to housing, the jobs/housing balance, and community recreation facilities. This alternative would meet project objectives relating to public access trails and the preservation of wetlands. · This alternative would be consistent with Coastal Act policies that caJl for the protection of coastal resources including upland areas. It would also be consistent with both County of Orange and City of Huntington Beach general plan policies relating open space, conservation and recreation. It would be inconsistent with the land use elements of the County and City General Plans which call for residential development of the project site. Feasibility: This alternative would require the acquisition and development of the project site by the public or a private conservation group. In addition, full implementation of this alternative would also require acquisition of the Lower Bench of the Bolsa Chica Mesa which is not a part of the project, and currentJy under litigation. The Lower Bench is currently Because no funding sources have been identified for this alternative, its feasibility is questionable. Finding: This alternative fails to achieve most of the project objectives. In addition, this alternative would not address the City and County's General Plan objectives relative to the need to provide housing to meet regional needs and improve the jobs/housing balance. The County 77 also considers this alternative to be infeasible in view of the lack of an identified funding source for the acquisition and implementation of the alternative. Consequently, the County considers this alternative less desirable as compared to the proposed project because there is no certainty that the alternative could ever be implemented in a feasible manner, as defmed by CEQA. For these reasons, the County finds that the proposed project is preferred over this alternative. Since this alternative could have eliminated some, if not all, of the significant unavoidable adverse environmental impacts of the proposed Project, the determination of infeasibility requires adoption of a statement of overriding considerations. 2. No Project/Existing General Plan Alternative Description: The project site is presently designated for residential development at a density of 0.5 to I 8 du per acre in the Orange County General Plan. The County portion of the site could be developed with between 52 and 1,895 dwelling units. The existing zoning limits the total number of dwelling units to 1,235. Less than two acres of the project site are located within the City of Huntington Beach. The Huntington Beach General Plan designates 1.6 acres for residential development at 7 units to the acre and designates a small portion of the site for residential agriculture uses which allows one residence per 4 acres. Environmental Effects: Under this alternative, a greater number of residential units could be developed and therefore this alternative would generally result in greater impacts than the proposed project. Several of the significant and unavoidable impacts of the proposed project would be incrementally worse under this alternative. These include long-term traffic impacts; short-term, long-term and cumulative air quality impacts and impacts to viewsheds. Development of this alternative would require the export of soils from the project site but the development area would remain comparable to the proposed project. No impacts would be reduced or avoided by this alternative. Ability to Achieve Project Objectives: This alternative would further .the project objectives relating to housing by increasing housing in a ·~obs rich" region. This alternative would be generally consistent with the objectives of providing community parks, .public trail access, and protecting and maintaining the on-site wetland. The density of this alternative, however, would result in a potential reduction in the open space and trails amenities as compared to the proposed project. This alternative would be consistent with the land use elements of the County and City General Plans and would be consistent with Coastal Act policies relating to the preservation of on-site wetlands. Feasibility: The development of this alternative would be feasible from an economic standpoint. Because no changes to the General Plan or zoning would be required, it is considered JegaJJy feasible as welJ. Finding: This alternative would accomplish some of the project objectives, but would not avoid or substantially reduce significant project impacts. The overal1 opportunities to provide recreation and open space amenities would also be reduced and the higher density housing product that would be required to achieve this density would be incompatible with the density of surrounding residential areas. The County, therefore, finds that the proposed project is preferred over this alternative. 3. No Project/No Development Alternative Description: Under this alternative, no new land uses and no intensification of existing land uses would be pennitted. The site would be retained in its current undeveloped condition and no physical changes would occur. Environmental Effects: This alternative would eliminate all impacts associated with development. The wetland habitat would remain marginally viable in its presently degraded condition. No public access would be provided and no public trails or recreational amenities would be developed. With respect to growth inducing effects, however, the County's and City's need and the regional demand for additional housing would remain even without the project. The goal of providing new housing opportunities would not be achieved. If housing is not provided as part of the project, additional housing demands will be placed on other undeveloped areas in the County and City. This alternative would avoid or reduce the following significant impacts of the proposed project: • Grading and construction emissions, including fugitive dust, would be avoided. • Long-term emissions of CO, ROC, and NOx would be avoided. • CumuJative emissions of NOx, ozone, CO would be avoided. • Changes to the viewshed of Bolsa Chica Mesa from PCH in the vicinity of Warner A venue and changes to the viewshed from Los Patos A venue would be avoided. Ability to Achieve Project Objectives: This a]ternative would not fulfill any of the project's objectives. Feasibility: Although in the short-term, this alternative would retain the site's existing characteristics, including its undeveloped state and bio1ogica1 resources, the retention of the project site in an undeveloped state would not be feasible in the long run. Without some fonn of intervention, such as acquisition by a public agency, the project site would be subject to development pressures over time. To date, no funding sources have been identified for the acquisition of the project site. In addition, as the property is privately-owned, the landowner is likely to continue to seek some productive, economical1y viable use of the property. Therefore, the long-term feasibility of no development occurring on this site is considered to be highly unlikely. Finding: Because this alternative would not accomplish any of the project objectives, would not address regional housing needs, and provides no long-tenn guarantee that the land would remain undeveloped absent the expenditure of public funds or known private funds (e.g., 70 non-profit entity) to purchase the property, this alternative is not considered feasible, and the County finds that the proposed project is preferred over this alternative. Since this alternative could have eliminated some, if not all, of the significant unavoidable adverse envirorunental impacts of the proposed Project, the determination of infeasibility requires adoption of a statement of overriding considerations. 4. AlternatJve Sites Description: A number of alternative sites were considered for the proposed development. These included the MCAS. El Toro and MCAS Tustin bases, the Holly-Seacliff project site, the Shea Homes/Parkside Estates site, and the Newport Banning Ranch site. As noted in Section 6.4.4 of the FSEIR., none of these sites was found to be viable alternative sites warranting further analysis. Environmental Effects: hnplementation of the proposed project at an alternative site would transfer most of the significant, unavoidable impacts of the proposed project to the alternative location. For example, site preparation, traffic, and energy use associated with the development of 388 units within the South Coast Air Basin would result in significant short- tenn, long-term, and cumulative air quality impacts at any alternative site. This alternative would avoid or reduce the significant impacts of the proposed project, including the following: • Changes to the viewshed of Bolsa Chica Mesa from PCH in the vicinity of Warner Avenue and changes to the viewshed from Los Patos Avenue would be avoided, however similar impacts would be expected at any of the alternative sites adjacent to existing development. • The intersection of PCH and Warner, which is subject to significant and unavoidable impacts even without the project, would remain impacted, but depending on the location of the alternative site, development on an alternate site may not contribute vehicle trips to this intersection. Ability to Achieve Project Objectives: Development at any of the alternative sites considered would not fulfill the project objectives. Feasibility: None of the aJternative sites were found to be feasible alternatives to the proposed project for the reasons set forth in Section 6.4.4 of the FSEJR Finding: For the reasons stated above and in Section 6.4.4, the County finds that the proposed project is preferred over this alternative. 5. Very Low Density Residential Development Alternative Description: This alternative considers the development of 106 dwelling units on the project site or a density of I dwelling units per acre. Individual lot sizes would be approximately 35,000 square feet in order to provide streets, sidewalks and the preservation of the on-site wetlands. There would be no recreation center or common area open space. RO Environmental Effects: Although this alternative would reduce several project impacts, in general the impacts would be the same as the proposed project. The development of this alternative would require the export of soil from the project site. The development area would be comparable to the proposed project. This alternative would reduce, but not avoid, the foJlowing significant impacts of the proposed project: • Long-tenn traffic impacts. • Short-tenn, long-tenn and cumulative air quality impacts. • Changes to the viewshed of Bolsa Chica Mesa from PCH in the vicinity of Warner Avenue and changes to the viewshed from Los Patos Avenue. Ability to Achieve Project Objectives: This alternative would further the project objectives of developing distinctive residential neighborhoods and providing housing that wilJ further the County's General Plan objectives for jobs/housing balance although not to the same degree as the proposed project. The wetlands would continue to be protected under this alternative. This alternative would not achieve the project objectives of providing a mixture of housing product and could limit the funding available for private parks, active and passive recreational facilities, and public trails. This alternative would potentially attain the policies of the County and City General Plans and the Coastal Act although less funding may be available to fund public amenities due to the reduced number of residential units available for sale. Feasibility: This alternative appears to be legally, technologically and social1y feasible. This alternative may not be financially feasible due to the fact that the infrastructure, open space and drainage requirements would be similar to the proposed project but a lesser economic return would be available due to the reduced number of units. Finding: Although this alternative would meet some of the project objectives and would reduce some of the significant unavoidable impacts it would not reduce these impacts to a level of insignificance. Because it may provide similar environmental impacts as the proposed project, but without the same level of public benefits provided, and because the economic feasibility of this alternative is questionable, and due to the reduction in funding available for parks, recreational amenities and trails, the County finds that the proposed project is preferred over this alternative. 6. Proposed Project with Perimeter Road Description: This alternative considers an alternative circulation system for the proposed project. This alternative features a loop road along the project site's western and southern perimeter, connecting Bolsa Chica Street to Warner Avenue. No other changes are proposed to the proposed project. Environmental Effects: Most of the impacts of this alternative would be the same as the proposed project. Implementation of this alternative, however, would introduce a public road adjacent to the Eucalyptus ESHA and the pocket lowlands, resulting in greater noise and light RI impacts than the proposed project, and leaving less area for trails and pedestrian staging. A public road at this location would also require extensive fencing to prevent unfettered access to native plant vegetation and pedestrian conflicts with vehicles on the public road. The amount of impervious surfaces would be increased which be likely to increase the size of the constructed wetlands. This alternative would not reduce or avoid any of the significant impacts of the proposed project. Ability to Achieve Project Objectives: This alternative would achieve the same objectives as the proposed project with the exception of the fact that this alternative would create more significant impacts than the circulation system for the proposed project. This alternative would reduce the flexibility in the design of the perimeter trail and view areas, introduce vehicles immediately adjacent to areas designated for open space and wetlands, and reduce the landscape buffer between residential development and public use areas. Feasibility: This alternative appears to be· legally, technologically, financially and socially feasible. Finding: Although this alternative would meet all of the project objectives. the impacts associated with the perimeter road are more significant than the circulation system for the proposed project. Because the circulation system for the proposed project better meets the objectives of the County and the Coastal Act and would have less impacts on sensitive habitat areas, the County finds that the proposed project is preferred over this alternative. 7. Drainage Design Alternative Description: This alternative considers two modifications to the proposed drainage system: a drainage connection to the EGGW Flood Control Channel and a connection to the Bolsa Chica Street-Los Patos Avenue stonn drain. The connection to the EGGW Flood Control Channel would require the placement of a pipe collection system through the Eucalyptus ESHA and the pocket lowland area. This alternative would require remedial grading approxjmately 120 feet in width and a permanent 2: 1 slope protecting an emergency access road covering the drainage pipe. Grading for the pipe would extend 80 feet into the Eucalyptus ESHA from the edge of the lowland area, would require filling wetlands in the pocket wetland and would result in the conveyance of drainage water into the Outer Bolsa Bay. The connection to the Bolsa Chica Street-Los Patos Avenue would create a connection to a storm water system which cannot accept additional flows. A new storm drain system would have to be constructed in the streets parallel to Los Patos A venue to accept the additional storm flows. A pumping system would also be required to move storm water up slope from the southern portion of the upper bench of the Bolsa Chica Mesa. This system would result in additional storm water runoff into Huntington Harbor. Environmental Effects: Most of the impacts of this alternative would be the same as the proposed project. Implementation of this alternative, however, would adversely impact the Eucalyptus ESHA and the pocket wetland, would convey storm water into the Outer Bolsa Bay 82 contrary to the objectives of the Coastal Commission, and would introduce additional runoff into Huntington Harbor further degrading water quality without additional mitigation. This alternative would not reduce or avoid any of the significant impacts of the proposed project. Ability to Achieve Project Objectives: This alternative would achieve the same objectives as the proposed project with the exception of the fact that this alternative would create more significant impacts than the drainage system for the proposed project. This alternative would adversely impact the Eucalyptus ESHA and the pocket wetland, convey storm water into the Outer Bolsa Bay contrary to the objectives of the Coastal Commission, and introduce additional runoff into Huntington Harbor further degrading water quality without additional mitigation which may not be permitted by the Santa Ana Regional Water Quality Control Board. Feasibility: This alternative appears to be infeasible from a legal and technological standpoint. Finding: Although this alternative would meet all of the project objectives, the impacts associated with the alternative drainage system are more significant than the drainage system for the proposed project. Because the drainage system for the proposed project is environmentalJy superior and better meets the objectives of the County and the Coastal Act, the County finds that the proposed project is preferred over this alternative. 7. STATEMENT OF OVERRIDING CONSIDERATIONS A. Introduction The County is the Lead Agency under CEQA for preparation, review and certification of the FSEIR for the Brightwater Project. As the Lead Agency, the County is also responsible for determining the potential environmental impacts of the proposed action and which of those impacts are significant, and which can be mitigated through imposition of mitigation measures to avoid or minimize those impacts to a level of less than significant. CEQA then requires the Lead Agency to balance the benefits of a proposed action against its significant unavoidable adverse environmental impacts in determining whether or not to approve the proposed project. In making this determination the County is guided by CEQA Guidelines Section 15093 which provides as follows: (a) CEQA requires the decision-making agency to balance, as applicable, the economic, legal, social, technological, or other benefits of a proposed project against its unavoidable environmental risks when determining whether to approve the project. If the specific economic, legal, sodal, technological, or other benefits of a proposal (sic) project outweigh the unavoidable adverse environmental effects, the adverse environmental effects may be considered "acceptable." (b) When the lead agency approves a project which will result in the occurrence of significant effects which are identified in the final EIR but are not avoided or substantially lessened, the agency shall state in writing the specific reasons to support its action based on the final Em and/or other infonnation in the record. The statement of overriding considerations shall be supported by substantial evidence in the record. (c) If an agency makes a statement of overriding considerations, the statement should be included in the record of the project approval and should be mentioned in the notice of detennination. This statement does not substitute for, and shall be in addition to, findings required pursuant to Section 15091. In addition, Public Resources Code Section 21081 (b) requires that where a public agency finds that specific economic, legal, social, technological, or other considerations, including considerations for the provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or alternatives identified in an Em and thereby Jeave significant unavoidable effects, the public agency must also find that overriding economic, legal, . social, technological, or other benefits of the project outweigh the significant effects of the project. Pursuant to Public Resources Code Section 21081(b) and the State CEQA Guidelines Section 15093, the County has balanced the benefits of the proposed Project against the folJowing unavoidable adverse impacts associated with the proposed Project and has adopted all feasible mitigation measures with respect to these impacts. The County also has examined alternatives to the proposed Project, none of which both meet the Project objectives and is environmentally preferable to the proposed Project for the reasons discussed in the Findings and Facts in Support of Findings. The County Planning Commission, acting as Lead Agency, and having reviewed the FSEIR for the Brightwater Project, and reviewed all written materials within the County's public record and heard all oral testimony presented at public hearings, adopts this Statement of Overriding Considerations, which has balanced the benefits of the project against its significant unavoidable adverse environmental impacts in reaching its decision to approve the project. B. Significant Unavoidable Adverse Environmental Impacts Although most potential Project impacts have been substantially avoided or mitigated, as described in the Findings and Facts in Support of Findings, there remain some project impacts for which complete mitigation is not feasible. For some impacts, mitigation measures were identified and adopted by the Lead Agency, however, even with implementation of the measures, the County finds that the impact cannot be reduced to a level of less than significant. For other impacts, no feasible mitigation measures were identified and no feasible alternatives were identified that would avoid or minimize these impacts. The impacts and alternatives are described below and were also addressed in the Findings. The FSEJR identified the foJlowing unavoidable adverse impacts of the proposed Project: Warner and Pacific Coast Highway. The proposed project will have a significant Jong-term adverse impact on traffic at the intersection of PCH and Warner Avenue. This intersection will experience a measurable traffic 84 contribution (based on both County and City performance criteria) from the proposed project and is projected to operate at LOS F. Impact 7.1 Equipment Exhaust. The proposed Project will result in potentially significant short-term construction related impacts from operation of construction equipment. Peak grading and construction emissions will exceed SCAQMD thresholds for the criteria pollutants NOx and PMl 0. Impact 7.2 Fugitive Dust. Fugitive dust emissions associated with demolition, land clearing, exposure, vehicle and equipment travel on unpaved roads, and cut and fill operations would exceed the SCAQMD threshold of 150 pounds per day. Nearby sensitive receptors and workers may be exposed to blowing dust. Impact 7.3 Area and Mobile Source Emissions. Emissions from on-site area sources alone would exceed the emission threshold for ROC established by the SCAQMD. Emissions from project-related mobile sources would exceed the operational thresholds for CO, RQC, and NOx established by the SCAQMD. Impact 10.1 Alteration of the Project Site from Public Viewsbeds. Residential development will permanently alter the undeveloped appearance of the Bolsa Chica Mesa within the public viewsheds as seen from Pacific Coast Highway near Warner Avenue and Pacific Coast Highway at the State Ecological Reserve Overlook, adjacent to Inner Bolsa Bay and a1ong Los Patos A venue at Bolsa Chica Street. The Project, when considered together with other related projects (including past. present and probable future projects) was also determined to have the following significant cumulative impacts: Warner and Pacific Coast Highway. The intersection is operating below optimum service levels and will continue to do so even without the project. The project's contribution to this cumulative impact is significant and adverse based upon both County and City performance criteria. Because capacity improvements at this intersection are currently constrained this impact cannot be mitigated and will remain a significant, unavoidable adverse cumulative impact Short and Long-Term Air Quality. Taken together with the construction and occupancy related emissions of other past, present and reasonably foreseeable projects, the project's emissions will have a cumulative impact on air quality in a basin that is non-attainment. Alteration of Views from Pacific Coast Highway. The Bolsa Chica Mesa is a prominent visual feature visible from Pacific Coast Highway. Both the project and the Parkside Estates project proposed for development on property adjacent to the project, are visible from Pacific Coast Highway. If development were to occur on the Lower Bench of the Bolsa Chica Mesa, that too would be visible from Pacific Coast Highway and would contribute to the alteration of the existing view of the bluff area from Pacific Coast Highway. The change in view from no 85 development to development as a result of the proposed project and related projects results in an unavoidable adverse cumulative impact. In addition, the FSEIR identified two alternatives that could avoid or substantially lessen the unavoidable environmental· impacts of the proposed project: the Biodiversity Park Alternative; and the No Project/No Development Alternative. C. Overriding Considerations The County, after balancing the specific economic, legal, social, technological, and other benefits of the proposed Project, has determined that the unavoidable adverse environmental impacts identified above may be considered acceptable due to the following specific considerations which outweigh the unavoidable, adverse environmental impacts of the proposed Project. 1. Conservation Open Space and Recreation Benefits. The project provides 28 , acres of planned Recreation and Conservation Open Space. With a total project area of 106 acres, this represents over 25% of the property being set aside for open space uses. Within this open space area, the project provides trails, protected and created wetlands, and protection of the eucalyptus environmentally sensitive habitat area. The 28 acres are located along the entire western and southern margin of the project site (Planning Areas 3A and 3B), and encompass the slope transition area leading to the Lower Bench. This area will support passive recreation open space uses, including trails as well as a series of linear ponds that will be created to provide on-site storm water retention and water quality management. In addition to 28 acres of open space that wil1 be dedicated on the Upper Bench of Bolsa Chica Mesa, the project also dedicates 49 acres for the Harriett Wieder Regional Park on the Huntington Mesa. This provides a total of 77 acres of dedicated public open space which is considerable when compared against the 78 acre development area for the proposed project. The specific details of the project's conservation and recreation elements are as listed below. Conservation Benefits 2. The design of the proposed project provides enhanced habitat protection for sensitive habitat areas over the level of development that is permitted on the project site under the current Planned Community Development Map that was approved in 1998 for the project site. The project preserves the existing Eucalyptus ESHA adjacent to the project site by converting 2 acres approved for residential development and 3 acres of Recreation area shown on the original 1998 Planned Community Development Map to 5 acres of Conservation (as shown on the 2002 Planned Community Development Map -First Revision). 3. To provide greater protection for the Eucalyptus ESHA and to ensure that no development will occur in the area in the future, the project (as noted on the 86 Brighwater Tentative Tract Map No. 15460) will place a Resource Preservation Easement over the ESRA. 4. The project applicant will dedicate the 5 acres of ESRA to the County of Orange for resource conservation purposes. The open space area adjacent to the ESHA, which ranges from I 00-200 feet wide, will be planted with Coastal Bluff Scrub and improved for public access and trails (outside the ESHA only). 5. The acreage of the Mesa Community Park within the Planned Community will be increased from 19 acres (as designated in the 1998 Balsa Chica Planned Community) to 34 acres under the current proposed project. These 34 acres will be designated for 7 acres of conservation and 27 acres of passive recreation. 6. The project will provide a native plant revegetation plan will provide a mix of upland native habitats, wetlands, interpretive and bicycle trails, and public information kiosks and viewing areas. 7. Approximately 9.6 acres of new Coastal Bluff Scrub habitat and 4.2 acres of new Coastal Prairie habitat will be planted within the Mesa Community Park. This habitat restoration program which wjJI provide 13.8 acres of native habitat will replace largely non-native vegetation that invaded the Mesa in the 201h Century following extensive fanning, and provides habitat that is considered rare in Orange County. Public Coastal Access and Recreation Benefits 8. In addition to increasing the Conservation area in the Community Park from 2 to 7 acres, the project wi11 convert land previously designated for residential development to open space, thus increasing the size of the Recreation area within the Mesa Community Park by 59% from 17 acres which was the land use designated on the original 1998 Planned Community Development Map to 27 acres as part of the currently proposed project reflected in the proposed 2002 Planned Community Development Map -First Revision. 9. The project applicant and landowner will dedicate to the County of Orange 23 acres of passive recreation area within the Mesa Community park with the development of the 388-home Brightwater community. This will provide 85% of the total master planned park in conjunction with a development proposal that constitutes only 31 % percent of the maximum number of units (1,235) shown on the County-approved 1998 Planned Community Development Map. IO. New Vehicular Public Access: To enhance public access and recreation, the project will construct a new park access road extending from the current terminus of BoJsa Chica Street to a new 30-space parking area within the community park that will allow recreational users to access trails and the open space area. Near the parking area, the project wm improve a public trailhead with an interpretive R7 Apr-05·08 22:46 From-CLERK Of THE BOARD 7148344439 T-978 P.01/01 F-459 kiosk and lockable racks for 20 bicycles. The extension of the road past the project entry is not needed for internal circulation or access for the residential developmenc, but is being constructed solely to provide public access to the open space areas. 11. Public Trails: The projecr will improve over 0.6 miles of public Class l (all season/multi-use) Trial for bicycles and pedestrians that connects the parking lot trailhead with Warner Avenue. The project will also connect various interpretive loops to points of interest within the park open space corridor and wm contain spur connections to linlc the project parking and trail improvements to existing and future County master plaJu1ed regional trails along Wamer Avenue, Pacific Coast Highway, Bolsa Chica State Beach and the State Ecological Reserve. The trail head at the parking area will include an informational kiosk describing the project's open space conidor, the narive vegetation, and wetlands. 11. The project will install fencing (to protect user impacts on habitat areas), interpretive signage, trail signs, and information kiosks and seating areas along the public rraH. 13. public Walkways: The project will improve walkways aJld sidewalks, in conjunction with the widening of Los Patos and the extension of Bolsa Chica Street that will allow the public to walk and bicycle not only through the Mesa Community Park, but the entfrc perimeter of rhe Brightwater conununity. 14. Han'.ien Wieder ReJ?ional Park: The project will irrevocably offer to dedicate to the County of Orange all 49 acres on the Huntington Mesa necessary to complete the County master-planned 106-acre Harriett Wieder Regional Park on the Huntington Mesa ponion of the Planned Community. This was a commitment from the prior, larger project described in FSElR. 551 that provided for the development of 3,300 homes on the Bolsa Chica property. However, with the reduction in the size of the project, there has been a substantial reduction in open space and recreational impacts. Despite the substantial reduction in recreational impacts resulting from the reduction of the proposed project from 3300 units to the 388 proposed under this project, the project has continued its corrunicment to dedicate 49 acres for the regional park system. 15. Increased Housing Opportunities. The proposed project provides 388 new housing units within an area that is considered ')obs rich." By providing new housing opportunities in an area that is jobs rich, the project helps further the County's Housing Element objectives which identify foture housing needs in the County, helps the County address its housing needs in accordance with the Regional Housing Needs Assessment, and furthers the Soutllem California Association of Government's Growth Management Plan's jobs/housing balance policy. 88 EXHIBIT D County of Orange Board of Supervisors adopted Mitigation, Monitoring and Reporting Program (This is a large document and is on-file with the Orange County Sanitation District's Board Secretary; please call 714-962-2411 to set up an appointment to review the document.) 5 , I.
