f . ' � 1. Project Overview � Introduction This report details the stormwater site plan and the detention pond design for the stocmwater ( mno:1'frorn a proposed faciliry for the Food Services of America(FSA). FSA proposes to build a � 153,141 square foot(froun and fresh cooler, and grocery dry goods) product disvibution wazehouse on 32.7 acres of the CSR Associated site. The building to be conswcted will be l Phase 1 of what eventually will be a 438,398 squaze foot building built out in two more phases. The facility will serve as a center for distribution of food products to north Puget Sound and I Olympic Peninsula FSA customers. There will be an above ground fuel tank and fuel pumps installed in Phase 1. Approximatel�• t,3501inear feet of new roadway will be built to provide access to the FSA site. The roauway will be built to City of Everett standards and dedicated to I the City of Everett. A stormH�ater detention pond with an open cell on the east and west ends (inlet azeas) and a wetland treatrwnt cell in the center(oudet) will be constructed in Phase 1. An oi1/water separator will be constructed in Phase 2 with the Maintenance Building under a stpazate � permit. IProject Location The project site is located within the CSR Associated property. 'fhe CSR Associated property is I bounded on the east by Glenwood Avenue,on the north by 60th Street S W(Merrill Creek Pazkway), on the west by Hazdeson Road, and on the south by Sievers Duecy Boulevazd. 'i'he FSA site is located along the west property line (central western portion) of the CSR Associated property in the I southwest quazter of Section 1,T.28N., R.4E., W.M.,in the City of Everett, Snohomish County, Washington. The FSA site is also known as Lot 1 on the proposed Binding Site Plan. See Figure 1 � for a vicinity map. I 2. Preliminary Conditions Summary Existing Conditions � The original topography of the project site sloped at about 3 percent from south to north, with the runoff from stormwater flowing into Glenwood Creek and Merrill&Ring Creek basins. The I existing topography of the site is changing daily because the current use is a gravel pit. Portions of the site are being mined while other ponions are being reclairtxd. The existing slopes vary from about 1 percent to vertical walls. Stormwater runoff from the existing gravd pit either � infilvates into the ground or flows into an on-site pond. The King's Exwsion Lot,just west of FSA (see Figure 1) is in both Glenwood Creek and Merrill&Ring Creek Basins. KinB's Extrusion has developed their property and discharges all the'v runoff to the Memll&Ring CYcek Basin. FSA stormwater runoff will be diverted entirely into the Glenwood Creek basin.
