IN WITNESS WHEREOF, I have hereunto set my hand and affixed the Seal of the City of Costa Mesa this 22nd day of February, 1989. ity Clerk and ex -officio Clerk the City Council of the City of Cos Mesa I v44 ATTACHMENT A STATEMENT OF FACTS SIGNIFICANT ENVIRONMENTAL EFFECTS OF THE PROPOSED PROJECT, FINDINGS WITH RESPECT TO SAID EFFECTS, AND STATEMENT OF FACTS IN SUPPORT THEREOF, ALL WITH RESPECT TO THE PROPOSED NORTH COSTA MESA SPECIFIC PLAN ARTERIAL IMPROVEMENT STUDY AND GENERAL PLAN AMENDMENT GP -89-1B IN THE CITY OF COSTA MESA. BACKGROUND State CEQA Guidelines (Guidelines) promulgated pursuant to the California Environmental Quality Act (CEQA) provide in part: "No public agency shall approve or carry out a project for which an EIR has been completed which identifies one or more significant 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 City of Costa Mesa proposes to adopt.the North Costa Mesa Specific Plan Arterial Improvement Study as a preliminary engineering and planning document, and to approve construction of roadway improvements at certain Project Areas in order to improve levels of service through year 2010. In addition, the City proposes to adopt a General Plan Amendment GP -89-1B for nineteen of the Project Areas described in the Arterial Improvement Study. Because the proposed actions constitute a project under CEQA and the Guidelines, the City of Costa Mesa has prepared a Program Environmental Impact Report (SCH #87072917) which includes an Addendum. The Program EIR identifies certain significant environmental effects which may occur as a result of the project. Furthermore, the City Council has determined not to implement improvements at Project Area Nos. 21, 23 and 24, as these locations are projected to maintain acceptable levels of service through year 2010, and, if implemented, would result in significant land use impacts. Therefore, findings are set forth herein pursuant to Section 15091 of the CEQA Guidelines. Conditions of Approval, provided in Attachment "C", are based on mitigation measures in the Final EIR. To ensure compliance with the mitigation measures as required by Section 21081.6 of the Public Resources Code, a reporting and monitoring program shall be adopted by the City of Costa Mesa. The program shall consist of a detailed written report for each Project Area outlining the method by which each applicable mitigation measure will be carried out, dates of completion and a list of the individuals responsible for the monitoring report. 1 Attachments A, B, C Resolution No. 89-18A Page 1 of 17 I A', 4c% �VP�! Land use impacts created by the project will involve temporary construction activity effects such as reduced access to some business uses and lane closures. However, mitigation measures will reduce short-term impacts to insignificant levels. Various long- term impacts will occur due to right-of-way acquisition, including loss of frontage and parking for commercial areas, residential frontage loss, reduced access at commercial and residential areas, loss of commercial and residential structures, and loss of landscaping. Finding (a) Changes have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effect as identified in the Final EIR. Facts in Support of Finding As detailed in Attachment "C" and in the Final EIR (pages 102- 113, the Addendum, and Responses to Comments), land use impacts will be mitigated to the extent feasible. Short-term impacts will be mitigated by maintaining access for commercial and residential areas at all times (short-term impacts are also mitigated through measures described in Circulation and Access, Climate and Air Quality, Noise and Public Services and Utilities). Long-term impacts will be mitigated through provision of compensation, as determined through a property appraisal and fiscal assessment for each affected parcel, as appropriate. Buffer/noise walls may be provided to offset frontage loss. A parking variance or alternative parking may be provided where resultant parking is below the minimum required. Relocation assistance will be provided as appropriate, pursuant to State and local law. Residential relocation and access mitigation are not required, although identified in the Final EIR, because locations where this would have been necessary are not proposed for approval with this Resolution (see below). Additional study and approval may be necessary where structure acquisition and demolition are required and will conform with applicable Federal, State and local laws. The City of Costa Mesa has determined that implementation of improvements at Project Area Nos. 21, 23 and 24 is not necessary at this time, as adequate levels of services are projected for these areas through the year 2010. These proposed improvements would have resulted in significant right-of-way acquisition, loss of commercial and residential structures and frontage, reduction of parking below City K Attachments A, B, C Resolution No. 89-18A Page 2 of 17 136— Parking Code requirements, and access limitations. Therefore, excluding these Project Areas from locations approved for construction will avoid significant environmental impacts. All significant environmental effects that can feasibly be avoided have been eliminated or substantially lessened by virtue of mitigation measures identified in the Final EIR and incorporated into the project as set forth above and in Attachment "C". EFFECTS NOT MITIGATED TO AN INSIGNIFICANT LEVEL Project implementation will result in the loss of four partial or entire structures and parking stalls at several locations because of right-of-way acquisition. Business losses may occur. (b) Specific economic, social, or other considerations make infeasible the mitigation measures or project alternatives identified in the Final EIR. Facts in SuRRort of Finding The unavoidable adverse impacts of the project are mitigated to the extent feasible. At each specific Project Area, necessary roadway improvements were determined based on various constraints, including land use, public service and utility facilities, and efficiency in transportation design. The Project Area improvements set forth in the Final EIR are considered the most desirable from a land use and transportation perspective. As identified in the alternatives section of the Final EIR, although other alternatives are not precluded by the project (such as Transportation System Management measures and improvements at additional locations), the proposed project is considered a critical element in the City of Costa Mesa's comprehensive effort towards providing adequate traffic flow through the year 2010. The remaining, unavoidable significant effect, if any, is acceptable when balanced against facts set forth above and in the Statement of Overriding Considerations which follows (Attachment "B"). CIRCULKTION AND ACCESS SIGNIFICANT IMPACTS The project will result in temporary access restrictions during construction. However, with required mitigation measures, this will be mitigated to less than significant levels. Long-term effects will be positive, as the project provides for improved traffic flow. However, Project Area Nos. 8 and 17 may experience long-term access impacts. See below regarding access impacts at Project Area No. 24. 3 Attachments A, B, C Resolution No. 89-18A Page 3 of 17 19`.7 Fines (a) Changes have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effect as identified in the Final EIR.

The impacts will be mitigated to the extenafe to bmltigate City will implement a Traffic Control Program temporary impacts. Access will be provided to all residential and commercial areas. Construction will be phased to the extent possible. Alternate access points will be provided at Project Area Nos. 8 and 17. The City of Costa Mesa has determined that implementation of improvements at Project Area Nos. 21, 23 and 24 is not necessary at this time, as adequate levels of services are projected for these areas through the year 2010. These proposed improvements would have resulted in significant right-of-way acquisition, loss of commercild beidenlowtial structures and frontage, reduction of parking Parking Code requirements, and access limitations. Therefore, excluding these Project Areas from locations approved for construction will avoid significant environmental impacts. All significant environmental effects that can feasibly be avoided have been eliminated or substantially lessened by virtue of mitigation measures identified in the Final EIR and incorporated into the project as set forth above and in Attachment "C". rT'FECTS NOT MITIGATED TO AN INSIGNIFICANT LEVEL If adequate alternative access points cannot be established at Project Area Nos. 8 and 17, significant long-term access impacts may occur. ind (b) Specific economic, social, or other considerations make infeasible the mitigation measures or project alternatives identified in the Final EIR. :_ �.,.,.,n,-r �f Finding Faca.S la, .�.+�+�+ The unavoidable adverse impacts of the project are mitigated to the extent feasible.

It should be noted that, for Project Area No. 17, the City is presently investigating additional alternatives for providing adequate levels of service at this intersection, in order to avoid access impacts of the proposed improvements. As identified in the alternatives section of the Final EIR, although other alternatives are not precluded by the project (such as Transportation System Management measures and improvements at additional locations), the proposed project is considered a critical element in the City of Costa Mesa's comprehensive effort towards providing adequate traffic flow through the year 2010. The remaining, unavoidable significant effect, if any, is acceptable when balanced against facts set forth above and in the Statement of Overriding Considerations which follows (Attachment "B"). CLIMATE AND AIR QUALITY SIGNIFICANT IMPACTS Short-term increases in dust will occur typical of construction activity. However, no significant temporary or long-term air quality impacts due to the project have been identified. Future traffic levels will result in higher pollutant concentrations along project roadways, which may result in the California standard for Carbon Monoxide being exceeded. This is not, however, an impact resulting from the project; on the contrary, the project is expected to reduce air pollutant concentrations by making traffic flow more efficiently. Finding No significant air quality impacts have been identified. Facts in Support of Findina Project construction will comply with applicable State and local construction requirements to minimize dust and odor generation. The project serves to provide regional air emission reductions, as it allows for more efficient traffic flow. As part of the City's comprehensive traffic improvement program, which includes the proposed project, the City will implement additional transportation measures which may further improve local and regional air quality. 5 Attachments A, B, C Resolution No. 89-18A Page 5 of 17 t AFRnETIcB SIGNIFICANT IMPACTS will result in temporary aesthetic impacts during The project which are not considered significant.

Facts in Support of Finding The unavoidable adverse impacts of the project are mitigated to the extent feasible. At each specific Project Area, necessary roadway improvements were determined based on various constraints, including land use, public service and utility facilities, and efficiency in transportation design. The Project Area improvements set forth in the Final EIR are considered the most desirable from a land use and transportation perspective. The City may provide buffer/noise walls where loss of frontage significantly affects an adjacent land use. As identified in the alternatives section of the Final EIR, although other alternatives are not precluded by the project (such as Transportation System Management measures and improvements at additional locations), the proposed project is considered a critical element in the City of Costa Mesa's comprehensive effort towards providing adequate traffic flow through the year 2010. The remaining, unavoidable significant effect, if any, is acceptable when balanced against facts set forth above and in the Statement of Overriding Considerations which follows (Attachment "B"). oIS SIGNIFICANT IMPACTS The project will result in temporary noise impacts, although these are not considered significant. No significant long-term noise impacts due to the project have been identified. However, existing and projected future traffic levels (which would be the same with or without the project), may expose residential areas to noise levels in excess of City standards. Finding No significant temporary or long-term noise impacts of the project have been identified. acts it Support of Findi In accordance with the City's adopted Arterial Master Plan, mitigation for noise impacts due traffic will be provided to qualifying existing areas. fr1 Attachments A, B, C Resolution No. 89-18A Page 7 of 17 Highway Wall to cumulative residential The City of Costa Mesa has determined that implementation of improvements at Project Area Nos. 21, 23 and 24 is not necessary at this time, as adequate levels of services are projected for these areas through the year 2010. These proposed improvements would have widened the respective roadways, resulting in increased road capacity and associated noise impacts due to greater future vehicle volumes. Therefore, excluding these Project Areas from locations approved for construction will avoid significant environmental impacts. PUBLIC SERVICES AND UTILITIES SIGNIFICANT IMPACTS Proposed improvements may affect existing and future public service and utility facilities. Project implementation will require extensive relocation of utilities and appurtenances. In addition, construction activities could delay emergency vehicles and school buses. Finding (a) Changes have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effect as identified in the Final EIR. acts in SuvDort of Findin As detailed in Attachment "C" and in the Final EIR (pages 216- 217, the Addendum, and Responses to Comments), impacts to Public Services and Utilities will be mitigated to the extent feasible. The City will, to the extent feasible, maintain service during construction. Appropriate fire, police and school agencies shall be notified prior to construction. Encroachment and improvement design will require review and approval of the applicable agency. The City of Costa Mesa has determined that implementation of improvements at Project Area Nos. 21, 23 and 24 is not necessary at this time, as adequate levels of services are projected for these areas through the year 2010. These proposed improvements would have resulted in significant right-of-way acquisition, including modifications to public service and utility facilities. Therefore, excluding these Project Areas from locations approved for construction will avoid significant environmental impacts. All significant environmental effects that can feasibly be avoided have been eliminated or substantially lessened by virtue of mitigation measures identified in the Final EIR and incorporated into the project as set forth above and in Attachment "C". 8 Attachments A, B, C Resolution No. 89-18A Page 8 of 17 I yf)t j Y+w `ky F m ATTACHMENT H STATEMENT OF OVERRIDING CONSIDERATIONS State EIR Guidelines (Guidelines) promulgated pursuant to the California Environmental Quality Act (CEQA) provide in part: "(a) CEQA requires the decision -maker to balance the benefits of a proposed project against its unavoidable environmental risks in determining whether to approve the project. Where agencies have taken action resulting in environmental damage without explaining the reasons which supported the decision, courts have invalidated the action." "(b) Where the decision of the public agency follows the occurrence of significant effects which are identified in the Final EIR but not mitigated, the agency must state in writing the reasons to support its action based on the Final EIR and/or other information records. This statement may be necessary if the agency also makes the finding under Section 15091 (a)(2) or (3)." "(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 Notices of Determination." (Section 15094 of the Guidelines.) The City Council proposes to adopt the North Costa Mesa Specific Plan Arterial Improvement Study, adopt General Plan Amendment GP - 89 -1B, and approve construction for all Project Areas except Nos. 21, 23 and 24. Because these actions constitute a project under CEQA and the Guidelines, a Program Environmental Impact Report (EIR) has been prepared by the City of Costa Mesa. The EIR has identified certain significant effects that will follow from this project even after incorporation of all feasible mitigation measures.' After determining that the program EIR is complete and has been prepared in accordance with CEQA and the Guidelines, and making the Statements of Facts above, the City Council has also weighed the significant effects of the project against the overriding consideration noted as follows: 1. The North Costa Mesa Specific Plan Arterial Improvement Study and Program EIR provide the City of Costa Mesa with important environmental and preliminary engineering design information for twenty-four locations in the City. The General Plan Amendment would ensure that all proposed improvements are consistent with the City's Master Plan of Arterial Highways. 9 Attachments A, B, C Resolution No. 89-18A Page 9 of 17 '203, 2. The project provides for adequate levels of service through the year 2010 through implementing roadway improvements at twenty-one locations in North Costa Mesa. Two possible exceptions are Project Area Nos. 11 and 19. However, level of service forecasts do not account for traffic flow improvements which may be achieved through bus turnouts and phasing, which may lead to acceptable traffic flow. Adequate levels of service are essential to the City's maintaining access for its residential, commercial and industrial areas, in addition to maintaining an acceptable quality of life for Costa Mesa residents. Adequate traffic flow is also essential to maintaining a viable commercial and tourism industry. 3. The project provides for bus turnouts as recommended by the Orange County Transit District, which serves to promote alternative transportation modes and reduce regional vehicle emissions. 4. The project provides improved traffic flow along Harbor Boulevard, a key element to the Orange County Transportation Commission's "Superstreets" program, designed to provide improved traffic flow along twenty- one major arterials in Orange County. 5. Improved traffic flow will improve local and regional air quality and will help to attain the objectives of the SCAQMD for the South Coast Air Basin. The City Council finds and determines that the above economic, social and environmental considerations outweigh the significant adverse environmental effects of the project. 10 Attachments A, B, C Resolution No. 89-18A Page 10 of 17 ATTACHMENT C CONDITIONS OF APPROVAL/INVENTORY OF MITIGATION MEASURES LAND USE 1. In all cases, potential economic disruption to adjacent businesses shall be minimized by maintenance of access to businesses, proper detours and directional signing to businesses, as determined necessary by the City of Costa Mesa (see Section IV.B. of the Final EIR). 2. The City of Costa Mesa will need right-of-way from adjacent land uses to implement the proposed roadway improvements, which shall be acquired as necessary. Impacted properties shall be appraised, and the value of land and structures shall be assessed. In addition, an evaluation of severance, potential loss of business as a result of the loss of frontage, parking spaces and structures or portions of structures shall be made. The following criteria shall be used in determining appropriate mitigation measures for specific land use impacts, as determined by the City on a case-by-case basis and in cooperation with the affected parties. All compensation shall be based on a property appraisal and fiscal assessment of other land use impacts. Commercial Land Uses a. Loss of Frontage: Compensation shall be provided on a unit cost basis (per square foot). In consideration of potential land use, aesthetic and noise impacts, the City may elect to provide buffer walls in lieu of or in addition to monetary compensation, particularly where resultant right-of-way is placed within 10 feet of an occupied building. b. Loss of Parking: Compensation shall be provided on a unit cost basis for right-of-way acquisition. Where loss of parking results in less than the minimum spaces required in the City parking code, the City shall consider issuance of a variance and may approve alternate parking areas or provide other compensation (see Table 1 in the Final EIR) . It is estimated that restriping remaining parking stalls as "compact" spaces can provide up to one additional stall per five stalls restriped. 11 Attachments A, B, C Resolution No. 89-18A Page 11 of 17 205 C. Partial Structure Loss (Loss of Retail Square Footage or Service Station Island): The City shall provide compensation based on a fiscal assessment of property value and potential lost revenue, or sh llacquIt ithe entire structure based on a property app y be possible to relocate service island(s). d. Structure Acquisition: Compensation shall be provided based on a property appraisal (see "Additional Study" below). In the case of displaced businesses, there is :bout to compensate for earning losses brought about through relocation (contained in the State of California Uniform Relocation Assistance and Real Property Acquisition Policies Act and in local ordinances). Residential Land U a. Loss of Frontage: Compensation shall be provided on a unit cost basis. In consideration of potential land use, aesthetic and noise impacts, the City may elect to provide buffer walls in lieu of or in addition to monetary compensation, particularly where resultant right-of-way is placed within 20 feet of an occupied residential building. b. Loss of Driveway Area: Compensation shall be provided on a unit cost basis. The elimination of driveway parking shall be partially mitigated by adding hammerheads or loops to driveways, where deemed necessary, due to shortened driveway lengths along the roadway, to provide easier driveway access and additional parking. The removal of driveway area along project arterials could also be partially mitigated by financial reimbursement to residents and/or provision of automatic garage door openers that reduce congestion by allowing quicker driveway access. The City may elect to acquire the entire property. Easements a. Richt-of-Way Acquisition: Compensation shall be provided on a unit cost basis. 3. Additional Study In several project areas, right-of-way acquisition will require demolition of structures and removal or relocation of service station islands. An environmental assessment of these properties will be required prior to their demolition, relocation or removal, in order to minimize potential environmental impacts (associated with potential presence of hazardous materials in affected structures). Further study 12 Attachments A, B, C Resolution No. 89-18A Page 12 of 17 is pending City determination of areas requiring improvement. All demolition and removal activities shall comply with applicable City and County requirements, South Coast Air Quality Management District regulations, Regional Water Quality Control Board requirements, State and Federal law regarding demolition of structures, and applicable safety requirements. Prior to demolition or removal, review and approval by additional agencies may be necessary. With adherence to applicable requirements, no significant impacts are anticipated. 4. Using the preceding criteria as a guideline, the City of Costa Mesa shall, in cooperation with affected parties, mitigate the land use impacts for each Project Area. The Final EIR provides a discussion of potential impacts for each Project Area (based on Drawings 1-1 through 24-1, the Impact discussion above and Table 1). Specific impacts at each Project Area will require mitigation pursuant to the criteria established in the program discussion above. If not otherwise stated, right-of-way acquisition requires removal of frontage, including landscaping, pavement and undeveloped areas. CIRCULATION AND ACCE 5. Short -Term Short-term impacts to building access and to intersection and bike lane use shall be mitigated by a Traffic Control Program to be established by the City of Costa Mesa. This program shall consist of prior notices, adequate sign -posting, detours, phased construction and temporary driveways where necessary. Adequate access shall be provided at all times to and from residences and businesses. Proper detours and warning signs shall be established for bike lanes to ensure public safety. Construction activities shall proceed in a timely manner to reduce impacts to.building access and bike lanes. The project areas shall be improved in phases based on need (see Section III.E. of the Final EIR). 6. Lona -Tena The project itself may be considered mitigation for existing and anticipated future traffic congestion. No further long- term mitigation is proposed. 7. Please refer to Section IV.B. of the Final EIR for a discussion of project area specific mitigation measures regarding access. 13 Attachments A, B, C Resolution No. 89-18A Page 13 of 17 CLIMAT S. Short -Term Impa Although no significant air quality impacts of the project have been identified, construction of the proposed project shall be required to be in compliance with SCAQMD Rule 403, which will reduce fugitive dust amounts by up to 50 percent. Dust reducing measures shall include regular watering of graded surfaces, restriction of all construction vehicles and equipment to travel along established and regularly watered roadways, and requiring that operations which tend to create dust be suspended during windy conditions. The project shall also comply with SCAQMD Rule 402, to reduce potential nuisance impacts due to odors from construction activities. 9. In addition to stationary source and land use controls applicable to existing and future projects utilizing project roadways, the following are applicable Transportation Source Controls that have been identified in the City of Costa Mesa General Plan (Environmental Resources/Management Element, page 23). The proposed project shall incorporate these measures where applicable. It should be noted that the project is, in itself, a mitigation measure for air quality impacts by improving traffic flow. a. Establish a computerized, integrated traffic signal network for major thoroughfares. b. Prohibit on -street parking along major arterials to increase capacity and improve flow. C. Modify intersections (turn restrictions, channelization, etc.) to improve flow and increase capacity. d. Restrict truck traffic during peak hours. e. Provide bike lanes and/or trails system to encourage reduction in motor vehicle trips. f. Coordinate bikeway planning with transit stop locations. g. Improve pedestrian and bicycle safety along local streets and roads. h. Reduce vehicular/bus conflicts by the construction of bus bays to remove buses from traveled lanes. 14 Attachments A, B, C Resolution No. 89-18A Page 14 of 17 AE$THETICB Although visual impacts will occur with implementation of the proposed arterial improvements, most are short-term in nature and will not persist after completion of construction -related activities (please refer to Section IV.A. of the Final EIR for additional mitigation measures related to aesthetics). Other more permanent impacts shall be mitigated by the following measures (no significant impacts of these measures have been identified): signs, and 10. furniturepeshall elements, be relocated or street replacedupon gpon project completion. 11. Bus turnouts and shelters shall contain furniture in accordance with the requirements of the Orange County Transit District's specifications. 12 included in wideningof improvements the road is Wife de is necessary, byn shall Where the City's Master Plan of Bikeways. 13. New sidewalks and curbs shall be provided where existing sidewalk is removed for roadway widening. 14. Landscaping removed by road widening shall be replaced on- site, where feasible, by similar species in appropriate locations. Where replacement of landscaping and trees is not possible in the immediate vicinity of the affected area, replacement shall be provided in adjacent or "off-site" areas to enhance other areas and offset project impacts. 15. To the extent feasible, drought -tolerant plant materials shall be used for new landscaping material. NOISE 16. Project construction and ongoing activities shall comply with the City Noise Ordinance. Specifically, the project will be required to limit construction hours to between 7:00 a.m. and 8:00 p.m. 17. In areas where projected traffic levels may affect qualifying existing residential areas, noise mitigation will be provided in accordance with the Arterial Highway Wall Master Plan, as described in Section XIV.C. of the Final EIR. 15 Attachments A, B, C Resolution No. 89-18A Page 15 of 17 BLIC_SERVICES 209 18. Where intersection improvements shall impact utility and service lines and appurtenances, the City of Costa Mesa shall modify the facilities or work with the appropriate agency to accommodate intersection expansions. These modifications include moving electric, gas, television, water and sewer lines. In addition, manholes, meters, boxes, storm drains and fire hydrants shall be adjusted to street grade. Several street lights, telephone and power poles and street signs within the project areas must also be moved. Facilities shall be relocated but will not be eliminated. Final engineering design shall be such that all public service and utility agency facilities are protected and/or adjusted per the applicable design standards. 19. The City shall coordinate with utility and service organizations to avoid disruption of service as a result of project implementation. 20. Underground Service Alert, an organization which alerts underground utility companies of excavation near their facilities, shall be notified prior to intersection improvement. 21. All bus turnouts shall be designed in accordance with applicable City standards and Orange County Transit District design guidelines. 22. Design plans shall be forwarded to the Mesa Consolidated Water District, the Orange County Water District and Metropolitan Water District for Project Areas affecting their facilities. The City shall, to the extent possible, ensure that the existing MWD O.C. feeder extension pipeline is not disrupted.
