TABLE 1-1 SUMMARY OF IMPACTS AND MITIGATION MEASURES <br />Significance <br />Before <br />Significant Impact Mitigation <br />shaking, seismic -related ground failure, including <br />liquefaction and lateral spreading. <br />GEO-2. The Project could result in substantial soil erosion <br />or the loss of topsoil. <br />Mitigation Measures <br />earthquake related impacts of strong ground shaking amplification <br />due to the soft underlying sediments, as identified in this DEIR. <br />Seismic ground motion parameters shall be provided in the <br />geotechnical reports in accordance with CBC requirements. The <br />building plans shall incorporate all design and construction criteria <br />specified in the report(s). The geotechnical engineer shall sign the <br />improvement plans and approve them as conforming to their <br />recommendations prior to issuance of building permits. The <br />geotechnical engineer shall also assume responsibility for inspection <br />of the work and shall certify to the City, prior to acceptance of the <br />work that the work performed is adequate and complies with its <br />recommendations. The geotechnical engineer of record shall <br />prepare letters and as -built documents to document their <br />observances during construction and to document that the work <br />performed is in accordance with the project plans and specifications. <br />As required by the City of San Leandro, all construction activities <br />shall meet the CBC regulations for seismic safety (i.e. reinforcing <br />perimeter and/or load bearing walls, bracing parapets, etc.). In <br />addition, all project -related grading, trenching, backfilling and <br />compaction operations shall be conducted in accordance with the <br />City of San Leandro Engineering Department's Standard Plans. All <br />improvements shall conform to regulations for seismic safety <br />contained in the CBC. <br />Significance <br />With <br />Mitigation <br />GEO-2A. The Project civil engineer shall prepare an erosion control LTS <br />plan. The erosion control plan shall be submitted to the City as a part <br />of building and/or grading plan submittal. The erosion control plan <br />shall conform to the guidelines of the Clean Water Program and <br />Utilize BMP's detailed under section "C6 CASCIA - BMPs Erosion <br />Control" of the Program Resources. <br />GEO-213: The existing rip -rap providing coastal erosion protection <br />shall be periodically refurbished to maintain effective erosion <br />control. This may include local replacement of rip -rap boulders as <br />well as periodic re -building of rip -rap armament sections degraded <br />by wave attack and/or long-term erosion. <br />
