8.B. - Page 53 <br /> 4.8 HAZARDS AND HAZARDOUS MATERIALS <br /> 4.8.1 Existin� Settin� <br /> All of Redwood City,including the project site,is located within the San Carlos Airport Influence <br /> Area(AIA). The project site is not located within the vicinity of a private airstrip. The project site is <br /> not near wildlands or otherwise subject to wildland fires. <br /> 4.1.8.1 On-Site Sources of Contamination <br /> The project site is not located on a site included on any list compiled pursuant to Section 65962.5 of <br /> the Government Code (Cortese List).�� <br /> Lead-Based Paint and Asbestos <br /> Lead was banned as an additive in paint in 1978. Asbestos containing materials (ACMs)were <br /> banned from many building materials in 1989. The existing single-family residence on the project <br /> site was constructed prior to 1978 and could contain lead-based paint and/or ACMs. <br /> Agricultural Use Impacts <br /> Historically,Redwood City was not used for major or large-scale agricultural production. <br /> Agricultural uses were generally limited to harvesting timber and small-scale farming and livestock <br /> activities. It is unlikely that the project site was used for farming. <br /> 4.8.1.2 Off-Site Sources of Contamination <br /> There are no sites in the vicinity of the project site listed on the California Department of To�c <br /> Substances Control (DTSC)Envirostor database,which is a listing of hazardous substance release <br /> sites selected for, and subject to, a response action. <br /> The Regional Water Quality Control Board(RWQCB)has a Geotracker database that keeps track of <br /> cleanup sites. The Geotracker database lists one leaking underground storage tank (LUST)within <br /> one half mile of the project site, appro�mately 0.40 miles west at 2108 Roosevelt Avenue. <br /> Groundwater in the vicinity of the LUST flows in an east-northeastern direction which is cross- <br /> gradient of the project site.�� Additionally,there are two LUST sites within a half mile of the project <br /> site to the northeast that have been remediated and issued case closure status. None of the listed <br /> LUST sites are located on properties on or immediately adjacent to the project site and there is no <br /> risk of direct soil contamination from documented off-site sources. <br /> ��The Cortese List is a plam�ing document that provides information about the location of hazardous materials <br /> release sites. <br /> ��Conestoga-Rovers&Associates.
