Acre Short Plat Stormwater Site Plan The project proposes to develop a currently vacant, approximately 0.64-acre site into a three single family lots. A number of trees of varying type, age, and health conditions exist on the site. Figure 2 in the Appendix displays the existing site conditions. The development will include three single family residences with three separate driveways, walls, a storm drainage facility, and associated utility connections. In addition,the project will include minor frontage improvements to Federal Avenue and Crescent Avenue in the form of pavement widening and providing a paved shoulder. All storm drainage controls for this project are proposed in accordance with City of Everett surface water standards, including the 2010 City of Everett Stormwater Management Manual and the 2019 Washington State Department of Ecology Stormwater Management Manual for Western Washington (DOE). Current site zoning of the property is R-1, Single Family. The proposed short plat is a permitted use under the current zoning and all site development and public infrastructure improvements are proposed in accordance with applicable City of Everett development standards. Figure 3 of the Appendix displays the proposed site conditions. The developed site is required to provide flow control facilities per current COE surface water standards. Most of the storm water runoff from the improved site will be collected and conveyed to a formal flow control facility prior to being released to the existing, downstream,combined sewer system. The project proposes a subsurface detention tank with a flow control riser to provide detention storage and flow control. The detention tank has been designed per City of Everett standards.
