Ordinance No.2217 Page 18 67 68 69 70 STORMWATER TREATMENT MEASURES INSPECTION AND MAINTENANCE AGREEMENT. The applicant shall enter into a "Stormwater Treatment Measures lnspection and Maintenance Agreement" for annual maintenance and reporting of the stormwater treatment system as depicted on the improvement plans City-approved by the Director of Engineering/City Engineer. The agreement shall be filed for record at the Alameda County Clerk-Recorder's Office at a time determined by the Director of Engineering/City Engineer. HYDROMODIFICATION MANAGEMENT: The project will create andior replace 1 acre or more of impervious surface and increase the total impervious surface area over the pre-project surface area and shall comply with Section "C.3.9 Hydromodification Management" of NPDES Permit No. CAS612008 and amendments, issued by the San Francisco Bay Regional Water Quality Control Board, except where on the three provisions stated in the permit applies. Post construction stormwater runoff shall drain to approved permanent Hydromodification Management (HM) controls to mitigate increases in peak runoff flow and increased runoff volume created by the project. The improvement plans shall include the Stormwater Management Plan, prepared by a California licensed civil engineer, indicating the type and locations of HM controls to be installed, sizing calculations using Bay Area Hydrology Model (BAHM). The Stormwater Management Plan shall be subject to review and acceptance by the Director of Engineering/City Engineer, prior to issuance of an engineering or building permit, whichever occurs first. Stormwater HM controls required under this condition shall be provided for in the Stormwater Treatment Measures lnspection and Maintenance Agreement. STATE OF CALIFORNIA CONSTRUCTION GENERAL PERMIT: A "Notice of lntent" (NOl) and "Stormwater Pollution Prevention Plan" (SWPPP) shall be prepared for construction projects disturbing 1 acre or more of land (including smaller sites that are part of a larger common plan of development). The applicant shall include the Waste Discharger ldentification Number (WDID) on the title sheet of the improvement plans and provide proof of coverage under the State of California Construction General Permit to the Engineering Department prior to the approval of the improvement plans by the Director of Engineering/City Engineer. STORMWATER POLLUTION PREVENTION PIAN: The applicant shall submit one hard copy and one PDF copy of the Stormwater Pollution Prevention Plan (SWPPP) for review and acceptance by the Director of Engineering/City Engineer prior to issuance of a building or engineering permit, whichever occurs first. A hard copy of the City-accepted SWPPP shall be available at the project site until all work is complete and engineering and building permits have been finaled. A site specific SWPPP shall be combined with proper and timely installation of the Best Management Practices, thorough and frequent inspections, maintenance, and documentation. Failure to comply with the reviewed construction SWPPP may result in issuance of correction notices, citations, or a stop work order. LANDSCAPE DESIGN: Landscape shall be designed to minimize runoff, promote surface filtration, and minimize the use of fertilizers and pesticides that contribute to stormwater pollution. Examples include: (a) design structures to prohibit the entry of pests, minimizing the need for pesticides; (b) install appropriate plants for the location in accordance with appropriate climate zones; and (c) install and maintain landscaping to treat stormwater runoff. 71
