POTENTIALLY <br />ISSUES <br />POTENTIALLY <br />SIGNIFICANT <br />LESS THAN <br />NO <br />SIGNIFICANT <br />UNLESS <br />SIGNIFICANT <br />rvIPACT <br />SOURCES <br />ISSUES <br />NETIGATION <br />IMPACT <br />INCORPORATED <br />LANATION: Continued <br />Prior to Final Map approval, the applicant shall be required to submit a site -specific final geotechnical report, to be <br />reviewed and approved by the City Engineer and Building Official. The report shall include but not be limited to a <br />detailed analysis of the site's expansive soils; potential for liquefaction, including a recommended development setback <br />from the top of creek bank; and the possible presence of undocumented fill associated with a former underground tank <br />excavation on a portion of the project site. Any recommendations contained in the report shall become conditions of <br />approval and be included on the plans submitted for building permit approval. <br />• Prior to issuance of a grading permit, the applicant shall submit all information, including a Grading Plan accompanied <br />by Soils Engineering and Engineering Geology Reports, in accordance with requirements of the City of San Leandro <br />Municipal Code Title VII, Chapter 12. <br />• Prior to issuance of grading permits for remediation of on -site contaminated soils, the applicant shall submit a report <br />that analyzes how the San Leandro Creek bank shall be stabilized, both during the grading and upon completion of the <br />remediation work, to minimize impacts to the creekbed itself. In addition, the potential loss of trees that currently occur <br />along the bank and provide stability shall be addressed in the report. This report shall be submitted for review and <br />approval to the City Engineer. <br />4. HYDROLOGY AND WATER QUALITY. Would the project: <br />a. Violate any water quality standards or waste <br />X <br />2 <br />discharge requirements? <br />b. Substantially deplete groundwater supplies or <br />X <br />2 <br />interfere substantially with groundwater <br />recharge such that there would be a net deficit <br />in aquifer volume or a lowering of the local <br />groundwater table level (e.g., the production <br />rate of pre-existing nearby wells would drop to <br />a level which would not support existing land . <br />uses or planned uses for which permits have <br />beengranted? <br />C. Substantially alter the existing drainage pattern <br />X <br />2 <br />of the site or area, including through the <br />alteration of the course of a stream or river, in <br />a manner which would result in substantial <br />erosion or siltation on- or off -site? <br />d. Substantially alter the existing drainage pattern <br />X <br />2 <br />of the site or area, including through the <br />alteration of the course of a stream or river, or <br />substantially increase the rate or amount of <br />surface runoff in a manner that would result in <br />flooding on- or off -site? <br />e. Create or contribute runoff water which would <br />X <br />2 <br />exceed the capacity of existing or planned <br />stormwater drainage systems or provide <br />substantial additional sources of polluted <br />runoff? <br />f. Otherwise substantially degrade water quality? <br />X <br />2 <br />g. Place housing within a 100-year flood hazard <br />X <br />11 <br />area as mapped on a federal Flood Hazard <br />Boundary or Flood Insurance Rate Map <br />(FEW) or other flood hazard delineation map? <br />Preda Street Homes - Initial Study Checklist 5 January 2001 <br />'` 1 <br />
