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 />No drain inlets exist on site. <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 />construction-and.lworking.-with-.the-City of Everett to -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 />Kikuchi SFR 21-0104 <br />September 2021 Page 7 <br />
