SAN LEANDRO SHORELINE DEVELOPMENT DRAFT EIR <br />CITY OF SAN LEANDRO <br />GEOLOGY, SOILS, AND SEISMICITY <br />Act states that "it is necessary to identify and map seismic hazard zones in order for cities and counties to <br />adequately prepare the safety element of their general plans and to encourage land use management <br />policies and regulations to reduce and mitigate those hazards to protect public health and safety." Section <br />2697(a) of the Act states that "cities and counties shall require, prior to the approval of a project located <br />in a seismic hazard zone, a geotechnical report defining and delineating any seismic hazard" <br />California Building Code <br />The California Building Code (CBC), known as the California Building Standards Code, is included in Title 24 <br />of the California Code of Regulations. The CBC incorporates the International Building Code, a model <br />building code adopted across the United States. <br />The CBC is updated every three years, and the current 2013 CBC took effect January 1, 2014. The 2013 <br />CBC has been adopted for use by the City of San Leandro according to Chapter 7 of Title 7 of the San <br />Leandro Municipal Code. Through the CBC, the State provides a minimum standard for building design <br />and construction. The CBC contains specific requirements for seismic safety, excavation, foundations, <br />retaining walls, and site demolition. It also regulates grading activities, including drainage and erosion <br />control. <br />Local Regulations <br />San Leandro General Plan <br />The City of San Leandro General Plan contains a goal and policies to minimize the risk of natural hazards, <br />including earthquakes and landslides, in Chapter 6, Environmental Hazards, of the General Plan. The <br />relevant goal and policies are listed in Table 4.5-1. <br />San Leandro Municipal Code <br />Chapter 7-12, Grading, Excavations, and Fills <br />Chapter 7-12, Grading, Excavations, and Fills, of the City of San Leandro Municipal Code maintains a <br />grading ordinance to mitigate hazards associated with erosion and land stability. The ordinance <br />establishes criteria for permits and identifies grading plan submittal and construction requirements. <br />Clean Water Program <br />The Alameda County Clean Water Program facilitates local compliance with the Federal Clean Water Act. <br />The City of San Leandro participates in the program. The Program establishes Best Management Practices <br />(BMP's) for erosion control during and after construction. BMP's related to erosion control address <br />preservation of existing vegetation, streambank stabilization, slope drains, and earth dikes and drainage <br />swales, to name a few. <br />An erosion and sedimentation control plan must be submitted with a grading permit application, along <br />with a drainage plan and pollution control plan. These plans ensure that any runoff from a project site <br />meets regional water quality standards. <br />4.5-2 DECEMBER 2014 <br />
