EXPLANATION: The project is to rezone the properties from residential and industrial designations to a commercial designation, No development is proposed as part this entitlement, and any future development of the sites would undergo separate environmental review. A records check and a preliminary screening was prepared for the five properties comprising the project site, by the Environmental Services Division of the City of San Leandro's Public Works Department. Internal City records indicate that surface soils contamination are a potential on the 2411 Washington Avenue site, due to its previous use as a paint company (Intercoastal Paint) which was abandoned after a large fire in 1962, One record of an open case in the San Francisco Bay Regional Water Quality Control Board (RWQCB, Region 2) was found for the parcel at 2411 Washington Avenue. It appears to be associated with the pump and treat system instal1ed on this site for treatment of the DW A-Singer Freiden plume (located to the east of the 1'ite.) Based on the DW A-Singer Freiden plume, there is a potential for this site to be impacted by solvents found in the DW A-Sing(~r Freiden plume. The DW A-Singer Freiden plume has been certified by DTSC with an Operations and Maintenance plan. Due to these pre-existing conditions, hazardous materials could be a potential1y significant impact and the fol1owing measure is ecommended to mitigate this impact to a less-than-significant level: Mitigation # 1: Prior to development of any future uses on the 2411 Washington A venue site, a Phase I Environmental Site Assessment shall be performed by a licensed professional to identify historic sources of soil or groundwater contamination. If recommended by the Phase I analysis, a Phase II analysis shall be performed and all recommendations of the Phase II analysis shall be implemented. Recommendations regarding further contamination characterization, and clean up shall be completed and a closure letter issued by the appropriate authority prior to any residential construction on these sites. Since many of the structures on the five sites are older (1970's and earlier), there is a potential for the presence of both lead-based paint (taken off the market in 1978) and asbestos, which was commonly used as a building material. If any of the existing structures on any of the four sites are to be demolished to al10w construction of new structures under the project, the following mitigation measure shall apply: Mitigation #2: Prior to any demolition, renovation or removal of structures on any of the project sites: a) An asbestos survey of existing structures shall be performed consistent with National Emissions Standards for Hazardous Air Pollution guidelines. If warranted, a remediation plan to remove asbestos shall be prepared and implemented. Said plan shall be consistent with applicable Fremont Fire Department standards, Bay Area Air Quality Management District requirement and Cal-OSHA standards. Necessary permits shall be obtained from al1 applicable regulatory agencies b) A lead based paint survey shal1 be conducted, If lead-based paint is encountered, the requirements as outlined in Cal OSHA Lead in Construction Standard, Title 8, CCR Section 1532.1 (or succeeding regulation) shall be followed. None of the four properties are located near public or private airports, airfields or airstrips. ;ince all of the sites are located on private property, any future construction facilitated as a result of this project would not block I emergency evacuation routes.
