area(steep slope,stream,wetland,landslide hazard area,etc.)and associated buffer. The construction <br /> management plan must include the following minimum measures: <br /> a. Specific erosion controls to be implemented prior to authorizing any construction activities which will <br /> impact an environmentally sensitive area as defined by the City's environmentally sensitive area <br /> regulations. <br /> b. For any facilities on or adjacent to erosion or landslide hazard areas,the construction management plan <br /> must address all mitigation measures identified in the geotechnical report approved by the Planning <br /> Director. <br /> c. Implementation of best management practices to control erosion both during and after construction, <br /> including compliance with the City of Everett's Design and Construction Standards and Specifications <br /> Manual and the Stormwater Management Manual. <br /> d. Construction schedule,status update reporting requirements,and contingency provisions to become <br /> effective if the schedule is not met. (SEPA Earth and Water Policies) <br /> 2. Prior to issuance of grading permits for removing earth from a site,the applicant must demonstrate that permits <br /> have been obtained for placement of the earth off-site. (SEPA Earth and Water Policies) <br /> During Construction/Earthwork <br /> 3. In order to minimize erosion during construction,all soil piles shall be covered with plastic sheeting or other <br /> impervious covering staked to the ground or anchored with rocks or sandbags. Berms,earthen or otherwise, <br /> must be constructed at the perimeter of excavated areas to prevent adjacent site runoff from entering the <br /> excavations. (SEPA Earth and Water Policies) <br /> 4. Temporary slopes within native glacial soils shall be limited to a maximum angle of 1/2 foot horizontal(H)to 1 <br /> foot vertical(V). Temporary slopes within fill soils shall be limited to a maximum angle of III:IV. Temporary <br /> slopes must be covered with an impermeable membrane,such as visqueen or mulch,in order to prevent <br /> precipitation from coming in contact with the soils. (SEPA Earth and Water Policies) <br /> Permanent slopes steeper than 25%shall be designed by a professional civil or geotechnical engineer. The <br /> design should present appropriate erosion control measures which may include:hydroseeding,erosion control <br /> blankets,rip-rap,jute matting,and visqueen. (SEPA Earth and Water Policies) <br /> 5. Grading/filling must not adversely affect the hydrology of streams and existing or created wetlands. (SEPA <br /> Earth and Water Policies) <br /> 6. Grading/filling on-site shall not adversely affect adjoining sites. (SEPA Earth and Water Policies) <br /> 7. Clearing limits shall be staked,flagged,and/or fenced off prior to initiation of any clearing or land alteration <br /> activities as approved by the Engineering and Public Services Inspector. Where the clearing limit is the edge <br /> of a geologically hazardous area or its buffer,the clearing limit shall be fenced during construction with a chain <br /> link or solid wooden fence a minimum of 4 feet high. <br /> 8. Following completion of construction and prior to issuance of occupancy permits,a permanent fence must be <br /> provided along the edge of the critical area buffer. The fence must be split rail or an alternative design <br /> approved by the Planning Director. Critical area signs must be posted on the fence. (SEPA Earth and Water <br /> Policies) <br /> 9. Removal of native vegetation within the building setback and buffer areas must be avoided when possible. <br /> (SEPA Earth and Water Policies) <br /> 6 <br />
