Will you construct during the wet season? <br />® Yes ❑ No <br />List and describe BMPs: <br />• BMP C122: Nets and Blankets per City of Everett Standard Drawing No 202 <br />• BMP C123: Plastic Covering <br />• BMP C125: Topsoiling <br />• BMP C130: Surface Roughening <br />In general, cut and fill slopes shall be stabilized as soon as possible and soil stockpiles shall be <br />temporarily covered with plastic coverings. All stockpiled soils shall be stabilized from erosion, <br />protected with sediment trapping measures, and where possible, be located away from storm <br />drain inlets, waterways, and drainage channels. Disturbed soils shall be stabilized using <br />temporary or permanent seeding, mulching, matting, compost blankets, or clear plastic <br />coverings. <br />Surface roughening will be used in the establishment of vegetative cover to help reduce runoff <br />velocity, increases infiltration, and provides for sediment trapping through the provision of a <br />rough soil surface. <br />At final site stabilization, all disturbed areas not otherwise vegetated or stabilized shall be <br />seeded and mulched. Final stabilization means the completion of all soil disturbing activities at <br />the site and the establishment of a permanent vegetative cover, or equivalent permanent <br />stabilization measures (such as pavement, riprap, gabions, or geotextiles) which will prevent <br />erosion. <br />The project site is located west of the Cascade Mountain Crest. As such, no soils shall remain <br />exposed and unworked for more than 7 days during the dry season (May 1 to September 30) <br />and 2 days during the wet season (October 1 to April 30). Regardless of the time of year, all <br />soils shall be stabilized at the end of the shift before a holiday or weekend if needed based on <br />weather forecasts. <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 />Page 110 <br />
