' o on all sites. Buildings must incorporate bicycle and pedestrian amenities such as lockers, shower rooms, and bicycle stands. Section 3: EARTH/GEOLOGICALLY HAZARDOUS AREAS 3.1 Threshold All slopes that are not designated environmentally sensitive may be modified. Major cuts and fills will likely occur to make sites suitable for development. 3.3 Mitigation Measures Prior to Construction 1. Construction management plans must be reviewed and approved by the Directors of the Planning and Community Development Department and the Engineering and Public Services Department prior to the issuance of permits allowing construction of any facilities located within 50 feet of an environmentally sensitive area (steep slope, stream, wetland, landslide hazard area, etc.) and associated buffer. The construction management plan must include the following minimum measures: a. Specific erosion controls to be implemented prior to authorizing any construction activities which will impact an environmentally sensitive area as defined by the City's environmentally sensitive area regulations. b. For any facilities on or adjacent to erosion or landslide hazard areas, the construction management plan must address all mitigation measures identified in the geotechnical report approved by the Planning 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 Standards and Specifications Manual and the Stormwater Management Manual. d. Construction schedule, status update reporting requirements, and contingency provisions to become effective if the schedule is not met. 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 earth off-site. During Construction/Earthwork 6. In order to minimize erosion during construction, all soil piles shall be covered with plastic sheeting or other impervious covering staked to the ground or anchored with rocks or sandbags. Berms, earthen or otherwise, must be constructed at the perimeter of excavated areas to prevent adjacent site runoff from entering the excavations. 8. Temporary slopes within native glacial soils shall be limited to a maximum angle of 1/2 foot horizontal (H)to 1 foot vertical (V). Temporary slopes within fill soils shall be limited to a maximum angle of 1 H:1V. Temporary slopes must be covered with an impermeable membrane, such as visqueen or mulch, in order to prevent precipitation from coming in contact with the soils.
