f 6e. Describe how you plan to construct each project element checked in 6d. Include specific construction methods and equipment to be used. [help] • Identify where each element will occur in relation to the nearest waterbody. • Indicate which activities are within the 100-year floodplain. While the proposed project is on a site which has already been filled, additional filling and grading will be needed prior to construction of the buildings. Temporary Erosion and Sediment Control (TESC) measures consisting of a construction entrance, silt fencing and seeding of disturbed soils will be installed using best management practices (BMPs) outlined in the Stormwater Pollution Prevention Plan (SWPPP) and TESC Plan prepared by the Project Engineer and approved by the City of Everett prior to implementation of the remediation actions. Once the entire site has been graded the contractor will move forward with building pads and building construction. The building sites and permanent stormwater facilities will be installed immediately following installation of TESC measures and all grading and road improvements. Equipment used during construction will be typical for land-clearing and grading activities and will be kept in good working order free of leaks. All equipment staging and materials stockpiles will be kept out of wetlands, streams, and regulated buffers, and the area will be kept free of spills and/or hazardous materials using a Spill Prevention, Control, and Countermeasure Plan (SPCC) prepared and implemented by the contractor. All clean fill material and road surfacing will be sourced from upland areas onsite or from approved suppliers, and will be free of pollutants and hazardous materials. All elements will occur within the 100-year floodplain of the Snohomish River and outside of the 50-foot set back from the Snohomish River. There will be approximately 14,200 cubic yards of cut to be removed from the site to an approved facility and 25,100 cubic yards of clean fill to be imported from an approved source. Net: 10,900 cubic yards. 6f. What are the anticipated start and end dates for project construction?
