2.3.2. Unless otherwise approved by the City Traffic Engineer, each development must submit a design traffic study that analyzes access capacity, site-specific safety issues, and site-specific construction impacts. The Traffic Engineer will use this study to set the design criteria that will apply to development proposals. Improvements necessary for safe and adequate access to a site are the responsibility of the developer, including traffic signals and roadways installed to provide direct access to a site. Facilities such as bus stops and shelters may also be required. Decisions by the Traffic Engineer may be appealed to the Hearing Examiner. (SEPA Transportation and Land and Shoreline Use Policies) 2.3.4.Transit routes/schedules and high occupancy vehicle information must be prominently displayed for employees at on-site commute information centers and near associated walkways. Preferential parking space locations for carpools and vanpools must be provided on all sites. Buildings must incorporate bicycle and pedestrian amenities such as lockers, shower rooms, and bicycle stands. (SEPA Transportation and Land and Shoreline Use Policies) SECTION 3: EARTH/GEOLOGICALLY HAZARDOUS AREAS 3.3.3.Any water quality enhancement or detention facilities proposed near steep slopes will require detailed geotechnical analysis and design that documents and ensures their safety. (SEPA Earth and Water Policies) 3.3.4. 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. (SEPA Earth and Water Policies) 3.3.5. All earthwork within a geologically hazardous area or its required buffer must be performed under the supervision of a professional civil or geotechnical engineer.The engineer must provide certification to the City that all work was done in compliance with requirements set forth in the City approved geotechnical report. (SEPA Earth and Water Policies) 3.3.6. 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. (SEPA Earth and Water Policies) 3.3.7. Mining sites must comply with the Department of Natural Resources reclamation requirements. On sites with existing mined slopes which are not subject to DNR regulations, slopes must be remediated to 1.5 horizontal : 1 vertical (1.5H: 1V), except for glacial till slopes which can be remediated to 1H:1V slope if approved by a qualified geotechnical engineer. All remediated slopes must be covered with top soil material that will support vegetation,jute matting or equivalent; and be revegetated with hydroseed,groundcover and shrubs. (SEPA Earth and Water Policies) 3.3.8.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 IH: 1 V.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, (SEPA Earth and Water Policies) Page of 20 3 Project No. REV120-036, REVI20-037, REVI20-03838 EVERETT
