Ordinance No. 1974 Page 20 of 21 Stormwater Construction Requirements 109. The project development shall submit a Stormwater Pollution Prevention Plan (SWPPP) for review and approval by the City Engineer prior to issuance of building or grading permits. 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. 110. The project developer is responsible for implementing the following measures during all construction phases of the project: a) The project developer shall 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/Chief Building Official. If no grading plan is required, necessary erosion control/storm water quality measures shall be shown on the site plan submitted for an on-site permit, subject to the review and approval of the Chief Building Official. The project developer is responsible for ensuring that the contractor is aware of and implements such measures. b) All cut and fill slopes shall be revegetated and stabilized after completion of grading, but in no case later than October 15. Hydroseeding shall be accomplished before September 15 and irrigated with a temporary irrigation system to ensure that the grasses are established before October 15. No grading shall occur between October 15 and April 15 unless approved erosion control/storm water quality measures are in place, subject to the approval of City Engineer/Chief Building Official. Such measures shall be maintained until such time as permanent landscaping is place. c) Gather all construction debris on a regular basis and place it in a dumpster or other container which is emptied or removed on a weekly basis. When appropriate, use tarps on the ground to collect fallen debris or splatters that could contribute to storm water runoff pollution. d) Remove all dirt, gravel, rubbish, refuse, and green waste from the street pavement and storm drains adjoining the site. Limit construction access routes onto the site and place gravel on them. Do not drive vehicles and equipment off paved or graveled areas during wet weather. Broom sweep the street pavement adjoining the project site on a daily basis. Scrape caked-on mud and dirt from these areas before sweeping. e) Install filter materials (such as sandbags, filter fabric, etc.) at the storm drain inlet nearest the downstream side of the project site in order to retain any debris or dirt flowing in the storm drain system. Maintain and/or replace filter materials to ensure effectiveness and to prevent street flooding. f) Create a contained and covered area on the site for the storage of bags, cement, paints, oils, fertilizers, pesticides, or other materials used on the site that have
