EXECUTIVE SUMMARY The data provided in this Stormwater Pollution and Prevention (SWPP)Narrative is provided for the purpose of evaluating the proposed new development and to comply with the minimum requirements set by the City of Everett Municipal Code and Stormwater Management Manual for Western Washington 2019 (SMMWW). The project site is located approximately 110 ft east of Dakota Way on 100th Street Southwest in Everett, Washington, within City of Everett limits. The project site is approximately 0.26 acres and has ground slopes that range from 2%to 8%to the south. There are no existing buildings on the parcel. Swamp Creek passes through the eastern portion of the property via an existing enclosed pipe. The parcel is covered in lawn. On-site soils in the area of development are consistent with Alderwood-Urban land complex. On-site stormwater appears to sheet flow and infiltrate into the existing native vegetated areas. The proposed project consists of construction of two single-family residences (SFR, ±2,910 sf w/overhang) with two asphalt driveways (±2,500 sf) and a concrete parking area (±325 sf). The proposed development will be located in the northern portion of the site. Stormwater runoff from the proposed SFRs will use Splashblocks, and stormwater from the proposed driveways will use sheet flow dispersion. Due to the type of soil on-site, together with other best management practices (BMPs) used on this proposed project, it is expected to meet the intent to provide both erosion control and stormwater treatment. For additional information, refer to the SWPP Elements below and the SWPP Plans. CONSTRUCTION SEQUENCE: 1. Arrange and attend pre-construction meeting with the city. 2. Flag clearing limits as indicated and install SWPP measures. 3. Construct buildings and driveways. 4. Stabilize disturbed land surfaces.
