The proposed <br /> project would be designed and constructed in accordance with standard engineering safety techniques <br /> and in accordance with a design-specific geotechnical report which is a standard requirement for <br /> building permits to meet the California building code and will be prepared for the project to reduce <br /> soils impacts to a less than significant level. (Less Than Significant Impact) <br /> In addition to following the recommendations of the design-specific geotechnical report,the project <br /> shall be designed and constructed in accordance with the 2010 California Building Code which <br /> contains the regulations that govern the construction of structures in California. Adherence to the <br /> 2010 Building Code would increase the likelihood of the project to resist minor earthquakes without <br /> damage and major earthquakes without collapse. (Less Than Significant Impact) <br /> Septic tanks or alternative wastewater disposal systems are not proposed as part of the project. (No <br /> Impact) <br /> 4.6.2.2 Construction Impacts <br /> Removal of the existing structures and grading of the site would expose soils and increase the <br /> potential for wind or water related erosion and sedimentation at the site until construction is <br /> complete. <br /> Impact GEO-L• Implementation of the proposed project would result in increased erosion and <br /> loss of top soil until the project is constructed. (Significant Impact) <br /> Mitigation Measures: The following measures have been included in the project to reduce potential <br /> construction related erosion impacts: <br /> Kensington Assisted Living Facility Project 38 Initial Study <br /> Redwood City Apri12013 <br />
