Preda Street Homes Mitigated Negative Declaration January 2001 C. The project area is located within the seismically -active Bay Area, therefore it is likely that during the lifetime of future residences constructed on the project site, they will be subject to seismic shaking and other earthquake -induced effects. San Leandro Creek acts as the northern site boundary, and development within its proximity could result in erosion of soils. The preliminary geotechnical report indicates that the site has a low to moderate potential for liquefaction; a moderate to high potential for expansive soils; and a low potential for differential compaction. Potential impacts related to soils stability and erosion can be adequately mitigated as long as mitigation identified by staff is implemented prior to Final Map approval and issuance of grading permits. The mitigation measures are conditions of approval. D. Given the existing on -site soils, the type of development proposed, and due to the fact that San Leandro Creek forms the northern project boundary, it can be anticipated that implementation of the proposed project may result in potentially significant impacts related to water quality, groundwater, drainage patterns, and increased run-off. Potential impacts related to hydrology and water quality can be adequately mitigated as long as mitigation identified by staff is measuresd prior to Final Mp areconditions of appr ovalproval and issuance of grading permits. The mitigation E. Dependant upon recommendations contained in the Final Remediation Action Program that is required for removal of on -site contaminated soils, the number of on -site trees proposed for removal could significantly increase, affecting both the creek bank stability, and the general aesthetics of the site. In addition, a raptor's nest that is located within an on -site tree could, if utilized, be affected by ,proposed grading activities and/or by the possible removal of the tree. Potential impacts related to biological resources can be adequately mitigated as long as mitigation identified by staff is implemented prior to approval of the Final Map and prior to issuance of grading permits. The mitigation measures are conditions of approval. F. The project site has been utilized for the last 50+ years for a variety of light industrial uses. A draft Remediation Action Plan (RAP) and analysis of on -site contaminants has been prepared for the project site, which indicates that removal of some on -site soils will be required. Potential impacts related to hazardous materials in relation to proposed residential development on the project sites can be adequately mitigated as long as mitigation identified by staff is implemented prior to approval of the Final Map and prior to issuance of grading permits. The mitigation measures are conditions of approval. G. The project area has both the elevated BART tracks and the Union Pacific railroad tracks located within close proximity. The existing noise environment for the property is within the maximum decibel level described in the General Plan as generally acceptable for residential development. However, single event noise sources (i.e. passage of diesel trains) exceed the maximum generally acceptable decibel level. Potential impacts related to noise exposure can be adequately mitigated as long as mitigation identified by staff is implemented prior to approval of the Final Map and prior to issuance of occupancy permits. The mitigation measures are conditions of approval. `'7C 2
