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 but <br />not limited to mulching (BMP C121), plastic sheeting (BMP _C123) or hydroseeding (BMP <br />C120), notes have been added to the plan regarding protection for the stock pile area if <br />necessary. A stockpile area has been identified on the SWPPP and is setback a minimum <br />of 10-feet from any down slope property line. In addition, during dry periods soil should be <br />covered or wetted (BMP C140) to reduce the production of dust. <br />. 6: Protect Slopes <br />All disturbed slopes on site during construction are required to be protected with mulch <br />(BMP .C121) or other means as specified in the construction sequence like surface <br />roughening'(BMP C103). No concentrated runoff or significant amounts of sheet flow will <br />be directed to new cut or fill slopes during construction (BMP C206).. <br />7: Protect Drain Inlets <br />The existing CB inlet will be protected with silt sock or other COE approved 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 no <br />formed areas are available, washwater and leftover product shall be contained in a lined <br />container and disposed of in a manner that does not violate water quality standards.. All <br />vehicles working on and around the site would need to meet the State requirements for <br />emissions.. A drip pan. or other, appropriate. temporary, containment device shall be placed <br />at locations where leaks or spills may occur during the fueling or maintenance of <br />machinery. <br />10: Control DeWatering <br />DeWatering is not anticipated for this project. <br />11: Maintain BMPs <br />The construction supervisor will be responsible for maintaining all BMPs during <br />- u construction-and:�roorking_with.the-City-of-Everettto relocate.,or..add:BMPs-as necessary as <br />site 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 />Moir SP Lot 6 <br />February 2020 <br />Revised., October 2020 <br />20-0108 <br />Page 7 . <br />
