6.4.A. - Page 110 3.0 Environmental Analysis 3.0 Environmental Analysis The 2010 FEIR for the Redwood City General Plan analyzed environmental impacts associated with adoption and implementation of the General Plan. Adoption of the Comprehensive 2013 Zoning Ordinance Amendment is a direct implementation measure of the General Plan (Program BE-1 of the General Plan) and is part of the project covered by the FEIR. This section reviews the conclusions of the 2010 FEIR and assesses the potential that changes to the City's zoning regulations, as manifested in the proposed Draft Comprehensive 2013 Zoning Ordinance Amendment, would have a new or revised impact on the environment. 3.1 Conclusions of the 2010 FEIR The 2010 FEIR for the Redwood City General Plan examined the impacts associated with the adoption and long-term implementation of the General Plan. The FEIR concluded that there were significant, unavoidable environmental impacts, impacts that could be reduced to less than significant with mitigation, impacts that were inherently less than significant, and impacts that were beneficial. The impacts identified to be significant and unavoidable were: Air Quality Impact 4.3-1: The projected population growth allowed by the New General Plan would be inconsistent with growth projections in the current regional Clean Air Plan, in that the projected population allowed by the New General Plan would increase at a greater rate than regional projections utilized within the Clean Air Plan. Transportation Impact 4.14-1: New development allowed under the New General Plan could cause an increase in traffic that is substantial in relation to the existing traffic load and capacity of the roadway system and result in unacceptable service levels on some roadway segments based on current LOS policy. Utilities Impact 4.15-4: Development allowed by the New General Plan could generate an increase in future demand for water supply that is not anticipated to be fully met by the City's existing and future water supplies. Global Climate Change Impact 4.16-2: The New General Plan would allow for new development to occur in areas that may be subjected to tidal inundation if sea level rises; this could place additional people and structures at elevated risk of exposure to flood hazards associated with long-term sea level rise. In total, the 2010 FEIR identified three beneficial impacts, 48 less than significant impacts, 19 impacts that were less than significant with mitigation, and the four significant and unavoidable impacts above. All impacts are outlined in Table 1: Comparison of Impacts 2010 FEIR and Comprehensive 2013 Zoning Ordinance Amendment. 3.2 Changes in Environmental Circumstances since October 2010 Since certification of the FEIR for the General Plan in October 2010, there have been no significant changes in environmental circumstances. No major development activity has been completed in the areas under consideration for changes to zoning. Given the existing urbanized condition of the areas proposed for zone changes, future development proposals would generally involve the demolition of existing structures and their replacement with new buildings and uses and would not affect any previously undisturbed areas. Individual developments within the plan area will be required to undergo project- specific environmental review pursuant to CEQA. No major roadway or other infrastructure improvements have been initiated in the areas under consideration since October 2010. Thus, no substantial changes Redwood City Comprehensive 2013 Zoning Amendment Page 20 of 51 Addendum to General Plan FEIR
