� �� i.� b. For any facilities on or adjacent to erosion or lancts]ide hazard areas, the construction management plan must address all mitigation meast,res identificd in the geotechnical repon approved by the Plannin�Director. c. Implementation of best management practices to control erosion both during and after construction, including compliance with the City of Everett's Design and Construction S[andards and Specifications Manual and the Stormwater Mana�ement Manual. d. Construction schedule, status update reporzing requirements, and contingency provisions to become effective if the schedule is not met. (SEPA Earth and Water Policies) Z. The Ci.y shal] require submittal of a geotechnical repoR when facilities aze proposed to be located in areas which contain potentially moisture sensitive soils. Moisture sensitive soils may include, but are not limited to,Tokul gravely loam, McKenna gravely silt loam,Teric Medisaprists, and Mukilteo muck. The following minimum mitigation requirements shall be met for all eaRhwork for facilities on moisture sensitive soils unless othenvise recommended in the geotechnical report: • Limit site disturbance by using tracked equiprnent, where possible, within the excavation area. • Remove standing water from the excavation azea. Outfall water should be filtered or run through a sedimentation basin. • Use surface erosion measures in areas in which surface water is anticipated to drain from the excavation area. Require control measures to be desigr.ed by a professional civil or geotechnical engineer, to prevent offsite surface drainage of sediments. Methods may include, but are not limited ro, use of silt fences and/or setdement �,onds. • Implement a plan to minimize the extent to which these soils become disturbed. Soils ��hich become disturbed, and which arr. above their optimum moisture content, should either be allowed to dry to within their optimum moisture content and be re-compacted, or be removed from the construction site. (SEPA Earth and Water Policies) 3. Any water quality enhancement or detention facilities proposed near steep slopes will require detai]ed geotechnical analysis and design that documents and ensures their safety. (SEPA Earth and Water Policies) 4. Prior to issuance of grading permits for removing earth from a site, the applicant must demonstrate that permits have been obtained for placement of the earr.h off-site. (SEPA Earth and Water Policies) Durine Construction/Earthworh 5. All earthwork within a aeo]ogically hazardous area or its required buffer must be performed under the supervision of a professional civil or�eotechnical eneineer. The eneineer must provide certification to the Ciry Ihat all work was done in compliance with requirements set forth in die City approved �eotechnical report. (SEPA Esuth and Water Policies) 6. In order to minimize erosion durin� construction, all soil Files shall be covered with plas[ic sheeting or other impervious covering staked to the ground or anchored with rocks or sandba�s. Berms, earthen or othenvise, must be conswcted at the perimeter of excavated areas to prevent adjacent site runoff from enterine the excavations. (SL-PA LaRh and Water Policiesl al
