As a result the City decided to prepare an Environmental Impact Report, and a Notice of Preparation was published and distributed fora 30-day review period on November 6, 2002; and, WHEREAS, the City has prepared a Draft Environmental Impact Report (DEIR), dated March 2003. The City observed a 45-day public review period for the document and held public hearings with the Planning Commission and the Historic and Cultural Preservation Committee (Historic SPARC) on March 25 and March 27, 2003, respectively; and, WHEREAS, the City has evaluated the comments received by public agencies, utilities, organizations, special interest groups and person who reviewed the DEIR, and has prepared a Final EIR responses to comments received during the 45-day public review period; and, WHEREAS, said comments received on the DEIR, and a list of individuals, groups, organizations, and agencies commenting on the DEIR have been included in the Final EIR for said project, as required by Section 15132 of the CEQA Guidelines. In addition, a Mitigation Monitoring and Reporting Program (MMRP) has been prepared to outline procedures for implementing all mitigation measures in the Final EIR; and, WHEREAS, the custodian of record of proceedings for this project is the Community Development Director; .and, Resolution No. 2003-104 N,C.S. W>FIEREAS, in accordance with Section 15097 of CEQA Guidelines, a Mitigation Monitoring and .Reporting Program (MMRP) has been prepared to outline procedures for implementing all mitigation measures in the Final EIR; and, WHEREAS, the Petaluma Environmental Review Guidelines and the CEQA guidelines require that the decision-making agency 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 a project. If these benefits outweigh the unavoidable adverse environmental effects, the adverse effects may be considered "acceptable." The decision-making agency must state. in writing the specific reasons to support its action based on the Final EIR and/or other information in the record. The statement of overriding considerations must be supported by substantial evidence in the record; and, WHEREAS, on April 21, and May 5, 2003, the City Council held duly noticed public hearings on the February 2003 Final Draft of the Central Petaluma Specific Plan, accepting all written and verbal reports and testimony. As part of this hearing process, the City Council has considered the Draft and Final EIR, recommendations by the Planning Commission, Historic SPARC and/or City staff, and comments received during the review process. NOW, THEREFORE, BE IT RESOLVED that the City Council does hereby make the following findings and determinations in accordance with the requirements of the City of Petaluma Environmental Review Guidelines and the California Environmental Quality Act (CEQA) Guidelines and the conclusions of the Final EIR for the Central Petaluma Specific Plan: EVALUATION OF PROJECT ALTERNATIVES The City Council finds as follows: a) Pursuant to CEQA Guidelines Section 15126.6, an EIR must describe a range of reasonable alternatives to the project, which feasibly could obtain most of the basic objectives of the project, but would avoid or substantially lessen the significant environmental effects of the project, and evaluate the comparative merits of the alternatives, and that the Final EIR for the Central Petaluma Specific Plan analyzed four alternatives to the proposed Central Petaluma Specific Plan: (1) No Project Alternative, (2) Existing General Plan Alternative, (3) 1999 Draft Specific Plan Alternative and (4) Mitigated Project Alternative. b) The No Project Alternative, Existing General Plan Alternative, 1999 Draft Specific Plan Alternative, as analyzed in the Final EIR, are hereby determined to either be infeasible or would not achieve the basic objectives of the project. City Council hereby finds and determines that the "Mitigated Project Alternative," which is the project as originally proposed, but with incorporation of the mitigation measures identified in the Final EIR, is the environmentally superior alternative. Reso. No. 2003-104 N.C.S. Page 2 STATEMENT OF OVERRIDING CONSIDERATIONS. The City Council finds as follows: 1. All of the significant impacts identified in the Final EIR have been or can be mitigated to a level of less-than-significant, with the exception of the following impacts: ® Transportation and Circulation Impact 6-3 (US 101 SB ramps/East Washington) ® Transportation and. Circulation Impact 6-4 (Lakeville/Caulfield) ® Transportation and Circulation Impact 6-7 (Lakeville/D Street) ® Transportation and Circulation Impact 6-13 (US 101) ® Transportation and Circulation Impact 6-14 (Roundabouts) ® Air Quality Impact 11-2 (Long-Term Regional Emissions) 2. Transportation and Circulation Impact 6-3 identifies that the Level of Service during the PM peak hour at the intersection of the southbound ramps of US Highway 101 and East Washington Street will deteriorate to less than acceptable conditions under Project Scenario 1, as described on page 6-18 of the FEIR. a) This impact will occur as a result of the level of development proposed in the Specific Plan, as well as the implementation of the proposed "road diets," the new local streets and roadway improvements called for by the plan, and the proposed elimination of the "Southern Crossing." It is also based on the assumption that none of the proposed transportation improvements called for by the 1987-2005 Petaluma General Plan, including improving the Washington Street over crossing and a new cross-town connector/Hwy 101 interchange. b) The Final EIR identifies Mitigation Measure 6-3, which calls for the construction of dual right turn lanes at the southbound ramp and dual left turn lanes on the westbound approach to US 101 on Washington Street. However, according to Table 6.6, these improvements will result in improved traffic operations, but not acceptable Level of Service conditions, whether or not the Specific Plan is adopted. 3. Transportation and Circulation Impact 6-4 identifies that under all cumulative scenarios, the intersection at Lakeville Street and Caulfield Lane would operate at unacceptable Level of Service conditions. c) This impact would occur with or without the development and circulation recommendations anticipated by the Specific Plan. d) The Final EIR identifies Mitigation Measure 6-4, which calls for providing an exclusive right-turn lane for the southbound approach on Lakeville Street and dual right-turn lanes for the westbound approach on Caulfield Lane. However, according to Table 6.6, these improvements will result in improved traffic Reso. No. 2003-104 N.C.S. Page 3 operations, but not acceptable Level of Service conditions, whether or not the Specific Plan is adopted. 4. Transportation and Circulation Impact 6-7 identifies that under all cumulative scenarios, the intersection at Lakeville Street and D Street would operate at unacceptable Level of Service conditions. e) This impact would occur with or without the development and circulation recommendations anticipated by the Specific Plan. f) The Final EIR identifies Mitigation Measure 6-7, which calls for providing an exclusive right-turn lane for westbound approach on D Street. However, according to Table 6.6, these improvements will result in improved traffic operations, but not acceptable Level of Service conditions, whether or not the Specific Plan is adopted. 5. Transportation and Circulation Impact 6-13 identifies that under all cumulative scenarios, the US Highway 101 between Washington Street and Old Redwood Highway would operate at unacceptable Level of Service conditions. g) This impact would occur with or without the development and circulation recommendations anticipated by the Specific Plan. h) The Final EIR identifies Mitigation Measure 6-13, which calls for widening Highway 101 to eight lanes. However, this mitigation measure has been determined to be prohibitively expensive and infeasible. 6. Transportation and Circulation Impact 6-14 identifies that under Project Scenario 1, the two proposed roundabouts (Washington and Copeland and D Street and Petaluma Blvd.) would result in unacceptable Level of Service operations at these two intersections. i) This impact will occur as a result of the level of development proposed in the Specific Plan, as well as the implementation of the proposed "road diets", the new local streets and roadway improvements called for by the plan, and the proposed elimination of the "Southern Crossing." It is .also based on the assumption that none of the proposed transportation improvements called for by the 1987-2005 Petaluma General Plan, including improving the Washington Street over crossing and a new cross-town connector/Hwy 101 interchange. j) The Final EIR identifies Mitigation Measure 6-14, which calls for a more thorough project specific traffic analysis of the configuration and alignment options that would accompany the design and implementation of the two roundabout proposals. However, because that level of analysis was not done as part of the Final EIR, the impact is considered significant and unavoidable. Reso. No. 2003-104 N.C.S. Page 4 7. Air Quality Impact 11-2 identifies that the long-term cumulative impact of development in accordance with the Specific Plan will provide some reduction of regional air quality impacts, but not to a less than significant level. k) This impact would occur with or without the development and circulation recommendations anticipated by the Specific Plan. 1) The Final EIR identifies Mitigation Measure 11-12, which calls for the application of various emission control strategies, where applicable, to reduce overall traffic generation. However, while it will assist in reducing project-related and cumulative impacts on regional air quality emission levels, no other feasible mitigation measures are available to further reduce regulated emission levels, whether or not the Specific Plan is adopted. The City Council hereby finds and determines that each of the overriding considerations set forth below constitutes separate and independent grounds ..for finding that the benefits of the project outweigh the significant unavoidable impacts of the project and is an overriding consideration warranting approval of the project. These matters are supported. by substantial evidence in the record that includes but is not limited to the Final EIR, staff reports and analyses, oral and written testimony, and other documents referenced in this Statement of Overriding Consideration and its adopting resolution. The principal benefits include, but are not limited to, the following: 1. The Specific Plan will provide the development potential for more than 1,600 new dwelling units and nearly 3,000,000 square feet of new commercial and industrial space that will reinforce the principles of infill development as expressed by the voter-adopted Urban Growth Boundary. 2. The Specific Plan will result in improvements to the roadway network that supports the vision of a vibrant, walkable, pedestrian-friendly environment by changing the character of existing major .streets (Lakeville and Petaluma Blvd.); making block perimeters more compact and walkable; installing roundabouts at Washington and Copeland and D Street and Petaluma Blvd. to calm traffic and mark the entry in the downtown; and ensuring street-level design and mix of uses that establish Central Petaluma as a destination for residents and visitors, alike. 3. The Specific Plan will result in the development and redevelopment of vacant and underutilized land within the Specific Plan area that presently are not in productive use and improve the cohesiveness of the downtown area. 4. The Specific Plan will increase the potential for expanded retail development, new employment and entertainment activities, while preserving the City's traditional river dependent and agricultural support industries. Reso. No. 2003-104 N.C.S. Page 5 5. The Specific Plan potentially will increase the number of persons who both work and live in Petaluma. 6. The Specific Plan will result in the successful implementation of the Petaluma River Access and Enhancement Plan and the Petaluma Bicycle Plan, as well as support public transit opportunities that will ultimately create effective alternatives to the use of private automobiles, thereby reducing the demand for parking and related air quality impacts. 7. The Specific Plan will be economically beneficial to the City of Petaluma by: a} generating retail sales taxes from new retail and other commercial uses; b) generating significant property taxes by encouraging new, more intensive development and redevelopment; and c) generating significant tax increment revenue for the Redevelopment Agency. 8. The Specific Plan will provide direction for the implementation of public improvements including but not limited to new or upgraded public utilities, streets, parking structures, bicycle and pedestrian ways and streetscapes. 9. The Specific Plan will result in the development of attractive buildings and site layouts that are consistent and compatible with surrounding historic developments and that are attractive and inviting to users and passersby. 10. The Specific Plan will result in a greater awareness of potentially historic resources within the boundaries of the Specific Plan area and recommends policies to protect and adaptively reuse those resources where reasonable and feasible. MITIGATION MONITORING AND REPORTING PROGRAM (MMRP) The City Council hereby finds and determines that the Mitigation Monitoring and Reporting Program (MMRP), attached hereto as Exhibit A, has been prepared in accordance with Section 15097 of CEQA Guidelines, and outlines procedures for implementing all mitigation measures in the Final EIR. Under the power and authority conferred upon this Council by the Charter of said City.
