7.D. - Page 40 of 126 City of Redwood City Mixed -Use Live/Work and Emergency Shelter Zoning Amendment Project Impact 4.3-3: The Redwood City General plan provides adequate buffers between new or existing sources of air pollutants (toxic air contaminants (TACs)) and new or existing residences or sensitive receptors, the General Plan does not address recent Bay Area Air Quality Management District (BAAQMD) guidance on protecting people from the risks of TACs. Consequently, allowable development under the General Plan may result in exposure of sensitive receptors to TACs. Less than The primary source of TAC emissions remains U.S. Highway 101 significant with traffic, industrial uses, and the port. The General Plan includes a mitigation mitigation measure to require that potential air quality impacts from new development projects be evaluated pursuant to the applicable BAAQMD CEQA Guidelines in effect at the time the City commences the air quality evaluation, which may include the establishment of specific overlay zones around existing and planned sources of TACs. Under the proposed project, this mitigation measure would continue to apply to projects in the MULW zone. Furthermore, the proposed project would not affect blocks within 500 feet of U.S. Highway 101 or the port. Impact 4.3-4: The increased population allowed by the General Less than Plan would increase traffic volumes along roadways, which significant could increase carbon monoxide emissions. An increase in carbon monoxide emissions from traffic along major roadways could violate air quality standards. Impact 4.3-5: Implementing the General Plan policies would Less than require adequate buffers between new or existing residences or significant sensitive receptors in accordance with the Clean Air Plan. 24 The proposed project could increase population by 1,269 residents over the population growth anticipated in the General Plan EIR for the year 2030. It could lead to additional traffic and carbon monoxide emissions, but 1,269 new residents would represent a small increase over the anticipated 2030 population (1.4 percent), and, the proposed project would concentrate development along existing transit corridors and in existing urban areas where goods and services are accessible to bicyclists and pedestrians. This would reduce vehicle trips and vehicle miles traveled compared to development in more car -dependent areas of the city. As described in Table 4.3-8 of the General Plan EIR, concentrations of carbon monoxide are anticipated to decrease substantially in the future with improvements to exhaust systems and reformulated fuels, and would not approach exceedance of applicable NAAQS or CAAQS thresholds. The proposed project would include no changes to Program PS -8 of the Public Safety Element. This program only allows new emissions or odor sources if the minimum screening distances between sources and receptors established in the BAAQMD CEQA Guidelines or other appropriate source can be met, or if detailed project -specific studies demonstrate compatibility with adjacent uses despite separations that do not meet the screening distance requirements. Similar to the conclusions in the General Plan EIR, the proposed project would result in less than significant impacts from TACs. No new or more severe impacts would occur. Impacts would be within the scope of those identified in the General Plan EIR. Similar to the conclusions in the General Plan EIR, the proposed project would result in less than significant impacts from population growth. No new or more severe impacts would occur. Impacts would be within the scope of those identified in the General Plan EIR. Similar to the conclusions in the General Plan EIR, the proposed project would result in less than significant impacts to new or existing residences or sensitive receptors. No new or more severe impacts would occur. Impacts would be within the scope of those identified in the General Plan EIR. 641
