Urban Stormwater Construction Requirements 81. To address the potential degradation of water quality in nearby surface water bodies by urban stormwater runoff from construction activities and post-construction land uses, the project developer and future lot owners/ contractors shall submit a Stormwater Pollution Prevention Plan (SWPPP) for review and approval by the City Engineer prior to issuance of grading permits for the subdivision and then building/grading permits for the individual lots. Failure to comply with the approved construction SWPPP may result in the issuance of correction notices, citations or stop work order. The following construction Best Management Practices (BMPs), as well as any other applicable measure, shall be included in the SWPPP and implemented as approved by the City Engineer. (Mitigation Measures H-2-a and G-1 of the FEIR.) 82. The project developer for the construction of the subdivision, the lot owner/contractor for the construction of homes on the individual lots, and then the homeowner after building occupancy are responsible for implementing the following measures during all construction phases of the project and the lots covered by this approval: (Mitigation Measures H-2-a and G-1 of the FEIR.) a. Include erosion control/storm water quality measures on the final grading plan which shall specifically address measures to prevent soil, dirt, and debris from entering the storm drain system. Such measures may include, but are not limited to, hydroseeding, hay bales, sandbags, and siltation fences and are subject to the review and approval of the City Engineer and/or the Chief Building and Safety Official as applicable. The project developer and the lot owner/contractor are responsible for ensuring that their contractors and sub- contractors are aware of and implement these measures. b. All graded lots shall be revegetated and stabilized after completion of grading, but in no case later than October 15th. The hydroseed mixture shall consist of the following species and rate-of-cover: crimson clover (20.0 Ibs/acre), California poppy (3.0 Ibs/acre), valley lupine (5.0 Ibs/acre), farewell-to-spring (2.0 Ibs/acre), and African daisy (2.0 Ibs/acre). The hydroseed mixture shall be specified on the subdivision's grading plans and the building permit plans for review and approval by the Planning Director. The hydroseeding shall be accomplished before September 15th and irrigated with a temporary irrigation system to ensure that the grasses are established before October 15th. No grading shall occur between October 15th and April 15th unless approved erosion control/storm water quality measures are in place, subject to the approval of City Engineer and/or the Chief Building and Safety Official as applicable. Such measures shall be maintained on each individual lots until permitted to be removed by the Planning Director and the Chief Building and Safety Official. c.
