Stormwater Pollution Prevention Plan General Introduction 1.0 Introduction This Stormwater Pollution Prevention Plan(SWPPP)has been prepared in accordance with the National Pollutant Discharge Elimination System (NPDES) stormwater permit requirements for the proposed commercial building located at 6605 Merrill Creek Parkway in Everett, WA within Section 2, Township 28 North, Range 4 East, WM. The 12.25-acre project area is within a 29-acre parcel. The parcel is bordered on the north and south by various industrial businesses and is bounded by Seaway Blvd. to the south, an industrial complex to the north and east, and a Corporate & Continuing Education Center to the west. Two existing driveways currently provide access to the site via Merrill Creek Parkway from the north and west. Existing topography on site is gently sloping and is currently undeveloped. Outside the area of disturbance there is a paved parking area, a small outbuilding, a firepit, and half size basketball court on the Northwest corner of the site encompassing approximately 3.00 acres, though these facilities will be unaffected by the proposed development. The site slopes with approximately 80-feet of fall from the southeast corner where there is a small hill to the northwest corner of the property. The majority of stormwater either drains directly into Narbeck Creek offsite or flows into Narbeck Creek through overflow of onsite wetlands. The frontage improvements lie within Powder Gulch basin. The full build-out of this project proposes the addition of a warehouse/commercial building, paved drives, parking areas,utilities, and frontage improvements. The purpose of this SWPPP is to describe the proposed construction activities and all temporary and permanent erosion and sediment control (TESC)measures, pollution prevention measures, inspection/monitoring activities, and recordkeeping that will be implemented during the proposed construction projects. The objectives of the SWPPP are to: 1. Implement Best Management Practices (BMPs) to prevent erosion and sedimentation, and to identify, reduce, eliminate or prevent stormwater contamination and water pollution from construction activity. 2. Prevent violations of surface water quality, ground water quality, or sediment management standards. 3. Prevent, during the construction phase, adverse water quality impacts including impacts on beneficial uses of the receiving water by controlling peak flow rates and volumes of stormwater runoff at the Permittee's outfalls and downstream of the outfalls. This SWPPP was prepared using the Ecology SWPPP Template downloaded from the Ecology website. It is based on the requirements set forth in the Construction Stormwater General Permit SNBL USA, LTD—Seaway Commercial Center SWPPP 1 August, 2022
