5: Stabilize Soils <br />The "Construction Sequence" calls for the stabilization of soils that remain unworked for <br />certain lengths of time based on the time of year. Stabilization techniques may include <br />but not limited to mulching, plastic sheeting or hydroseeding, notes have been added to <br />the plan regarding protection for the stockpile area if necessary. A stockpile area has <br />been identified on the SWPPP and is setback a minimum of 10-feet from any down slope <br />property line or critical area. <br />6: Protect Slopes <br />All disturbed slopes on site during construction are required to be protected with mulch <br />or other means as specified in the construction sequence. No concentrated runoff or <br />significant amounts of sheet flow will be directed to new cut or fill slopes during <br />construction. <br />7: Protect Drain Inlets <br />The catch basin on Ocean Ave will be protected with a sock filter or other COE approved <br />method. <br />8: Stabilize Channels and Outlets <br />No new channels or outlets are proposed for this site. <br />9: Control Pollutants <br />No outside chemicals are expected to be necessary for the construction of this project. <br />Concrete truck chutes, pumps, internals, and hand tools shall be washed out only into <br />formed areas awaiting installation of concrete or asphalt. Unused concrete remaining in <br />the truck and pump shall be returned to the originating batch plant for recycling. When <br />no formed areas are available, wash water and leftover product shall be contained in a <br />lined container and disposed of in a manner that does not violate water quality <br />standards. All vehicles working on and around the site would need to meet the State <br />requirements for emissions. A drip pan or other appropriate temporary containment <br />device shall be placed at locations where leaks or spills may occur during the fueling or <br />maintenance of machinery. <br />10: Control Dewatering <br />Dewatering is not expected for this project. <br />11: Maintain BMPs <br />The construction supervisor will be responsible for maintaining all BMPs during <br />construction and working with the City to relocate or add BMPs as necessary as site <br />conditions change. <br />12: Manage the Project <br />It will be the responsibility of the Contractor and Developer to manage this project and <br />coordinate with the City Inspector and Engineer. <br />Haack — 74th 22-0807 <br />September 2022 Page 7 <br />
