PLN2009-00006; 2450 Washington Avenue October 2011 Mitigated Negative Declaration Mitigation Measure #18: Prior to issuance of a grading permit, the project applicant must prepare and implement an erosion and sediment control plan (ESCP) including interim and permanent erosion and sediment control measures and a pollutant control plan (PCP). Mitigation Measure #19: Prior to issuance of a grading permit, the project applicant shall file the required documentation to the State Water Resources Quality Board and prepare a Storm Water Pollutant Prevention Plan (SWPPP) which will be reviewed and approved by the City Engineer. The City Engineer must conduct inspections prior to issuing a certificate of occupancy, to ensure that requirements are complied with. Mitigation Measure #20: The applicant will comply with applicable waste discharge requirements and municipal code requirements including preparation of a SWPPP for construction activities and compliance with the Alameda Countywide Clean Water Pro gr a m (ACCWP). These permit programs are designed to prevent violation of water quality standards through mitigation and control of pollutant transport in storm water runoff and infiltrating waters. The City of San Leandro Municipal Code ensures that permit conditions are met. Mitigation Measure # 21: Applicant shall be required to demonstrate adequacy of the existing storm drain system to handle existing run -off from the drainage basin as well as run -off from the project, upgrade the storm drain system to handle existing run -off from the drainage basin as well as run -off from the project, or meter run -off from the site so that it leaves the site at the same rate as it currently does. Mitigation Measure #22: To reduce imperviousness, the applicant shall minimize use of concrete walks and hardscape areas. Planters and landscape areas shall be maximized and bioswales, paver blocks, decomposed granite and other alternative pavement materials will be utilized to promote groundwater recharge. Mitigation Measure #23: The applicant shall comply with the applicable City of San Leandro Engineering and Building standards as part of the entitlement process to ensure that new construction is designed to minimize the potential for damage from flooding. Mitigation Measure #24: To meet Building Code DNL 45 dB requirements, it will be necessary for some of the building facades to be sound rated, as indicated in Figure 2 of the September 24, 2008 Acoustical Study prepared by Charles M. Salter Associates, Inc. STC ratings for selected assemblies shall be based on laboratory testing performed in accordance with ASTM E -90 and comprise the entire window or door assembly, including the frame. If non - tested assemblies are to be used, an acoustical consultant must review the glazing and frame submittals, and the STC rating of the glass may need to be increased. A typical construction -grade 1 -inch insulated, dual -pane window achieves an STC rating of approximately 28 to 30. Mitigation Measure #25: The applicant shall incorporate lighting, landscaping and other design features that reduce the potential for crime and facilitate rapid response to emergency calls in accordance with General Plan Policy 45.06.
