The design is intended to meet the requirements of the current City of Everett Drainage Code, including by reference the City of Everett 2021 Section 4—Storm and Surface Water Design and Construction Standards and Specifications for Development and the Department of Ecology(DOE) 2019 Stormwater Management Manual for Western Washington. Location The proposed project is at a mobile home property located at 1427 100th ST SW Everett, WA 98204.The project is within the City of Everett city limits and zoned as Urban Residential 3.The parcel consists of a total area of 29.68 acres (1,293,152 SF).The subject area is bounded by 100th ST SW to the south and residential properties to the west and east and a golf course to the north and northeast. See Figure 1 Appendix A. Proiect Description The proposed project includes the widening of the entrance to Fairway Estates MHC,vehicle entry and exit gates including opening mechanisms and entry call box, pedestrian gate,feature wall and columns, and entry signage. The project will create 1,394 sf of new hard surface and replace 2,761 SF of existing hard surface(new plus replaced hard surface is 4,144 SF). Existing Stormwater There is an existing catch basin along the west edge of the entrance and another at the west corner of the entry drive and 1001h St SW. Stormwater from these two catch basins collect stormwater runoff from the driveway and conveys it to a catch basin 12" storm line that is part of a public storm drain system in 100th St SW.The public system discharges to Swamp Creek approximately 375 feet from the site. See Figure 6 Offsite Map in Appendix A. Proposed Stormwater Improvements A catch basin is added to pick up flow from a low spot in the road. SECTION 2: CORE REQUIREMENTS SUMMARY The proposed project area is 8716 SF.The project meets the criteria of a redevelopment project because greater than 35%of the project site consists of existing hard surfaces. As such, 14.28.030 City of Everett Municipal Code (and Figure 1-3.2 from the DOE Manual, included as Figure 9 in Appendix A)was used to determine applicable minimum core requirements. Because the project is proposing less than 5,000 sf of new hard surface, is not converting any native vegetation to lawn or landscape, and is not converting any native vegetation to pasture, only the first five minimum requirements are applicable to the project.This is a road-related project, so application of the Flow Chart (See Figure 9) results in the determination that only MR's 1-5 apply to the project. Application of the core requirements are addressed below. Fairway Estates MHC Entry Huitt-Zollars Stormwater Drainage Report December 15,2023 Everett,Washington Page 1
