8.A. - Page 93 Section 4: Evaluation of Environmental Impacts c) Less than Significant Impact. Residential land uses do not typically produce excessive noise either individually or cumulatively that could substantially increase existing, ambient noise levels. Future development on the Opportunity Sites will increase ambient noise levels due to increased traffic generation in the project vicinity. The proposed Housing Element does not include changes to land uses and intensities designated in the current General Plan and analyzed in the EIR. The Housing Element does not propose any specific development or any land use changes that will invalidate this prior finding or further increase traffic levels beyond those analyzed in the General Plan EIR. Project specific increases in ambient noise levels due to future development on each Opportunity Site will be evaluated as development is proposed over the long- term pursuant to existing policies and procedures. With these existing policies and procedures, impacts related to increases in ambient noise levels will be Tess than significant. d) Less than Significant Impact. The proposed Housing Element does not authorize the development or redevelopment of any particular site but does include policies that could facilitate development of future housing. Temporary increases in local noise levels will be associated with construction activities to develop new housing. Construction noise will be controlled through the time restrictions currently established in the City's noise control requirements. The updated Housing Element will not result in any new or more severe temporary noise impacts associated with residential construction as the Housing Element does not propose land uses or intensities not already designated in the General Plan and analyzed in the EIR. Continued enforcement of the City's noise restrictions will reduce temporary noise impacts associated with the proposed Housing Element to a Tess- than - significant level. e -f) Less than Significant Impact. No private airstrips are located within or in the near vicinity of the plan area. The closest airport is San Carlos Airport, which is a public general aviation facility located along U.S. 101 near Redwood Shores. As such, the allowed development and associated increase in population from the proposed Housing Element will not be exposed to excessive noise levels generated by a private airstrip. According to the noise contours included in the 1996 San Mateo County Comprehensive Airport Land Use Plan, no Opportunity Sites lie within the 65 dBA CNEL contour and thus will not be impacted by airport operations. Airport noise impacts will be Tess than significant. 54 Redwood City Housing Element Initial Study
