Storm drain protection shall remain in place <br />until project completion as determined by the owner. <br />Silt fence will be installed along the downslope side of the project to contain stormwater on site. <br />Silt fence reduces the transport of coarse sediment from a construction site by providing a <br />temporary physical barrier to sediment and reducing the runoff velocities of overland flow. <br />The contractor shall upgrade the SWPP facilities to account for severe storm events or if the <br />SWPP facilities are ineffective at preventing turbid water from leaving the site. <br />Installation Schedules: Prior to earthmoving activity and maintained throughout construction. <br />Inspection and Maintenance plan: Wet Season: Weekly and within 24 hours after heavy rainfall, <br />Dry Season: Monthly and within 24 hours after rainfall. Also, per current edition of City of Everett <br />Stormwater Management Manual. <br />Responsible Staff: CESCL <br />2.1.5 Element 5: Stabilize Soils <br />West of the Cascade Mountains Crest <br />Season <br />Dates <br />Number of Days Soils Can <br />be Left Exposed <br />During the Dry Season <br />May 1 — September 30 <br />7 days <br />During the Wet Season <br />October 1 — April 30 <br />2 days <br />Soils must be stabilized at the end of the shift before a holiday or weekend if needed based on <br />the weather forecast. <br />Anticipated project dates: Start date: August 2018 End date: December 2018 <br />Page 19 <br />
