1 5. Permanent Stormwater Control Plan <br />' As discussed at the November 9, 2017, meeting between the Port of Everett team and the City of Everett <br />Planning Department, Jane Zimmerman, prior to retirement, had confirmed that the project does not require <br />any water quality or flow control improvements. Stormwater is managed through grading to encourage sheet <br />' flow toward the Snohomish River. The proposed trail has been designed to match existing topography for the <br />most part, thus during rainfall events runoff will follow the existing path over the trail on its way out to the <br />Snohomish River. All existing berm low points are maintained to allow stormwater to reach the river during <br />rainfall. See Table 5-1 for the project area summary and Appendix A3 for the proposed grading and drainage <br />plans. <br />Table 5-1: Project Area Summary <br />Total Project Area* <br />1.066 acres <br />New Hard Surfaces <br />0.648 acres <br />Replaced Hard Surfaces <br />0 acres <br />Converted Pervious Surfaces <br />0 acres <br />* Total project area excludes existing areas to be planted or to receive soil amendment that are otherwise undisturbed. Including plantings <br />and soil amendments, the disturbed area totals 3.212 acres. <br />6. Construction Stormwater Pollution Prevention Plan <br />' (SWPPP) <br />Stormwater Pollution Prevention BMPs will be provided to minimize the risk of sediment laden runoff entering <br />the natural drainage systems. The following list of BMPs will be provided throughout construction and <br />amended to meet site conditions as necessary. See Appendix B for the SWPPP. <br />• BMP C233: Silt Fence per City of Everett Standard Drawing No. 214 <br />• BMP C220: Storm Drain Inlet Protection per City of Everett Standard Drawing No. 210 <br />I <br />• BMP C105: Stabilized Construction Entrance/Exit per City of Everett Standard Drawing No. 201 <br />• BMP C208: Triangular Silt Dike per City of Everett Standard Drawing No. 207 <br />' • BMP C200: Interceptor Dike and Swale <br />7. Special Reports and Studies <br />Special reports prepared for the project include the Biological and Floodplain Assessment by Hart Crowser and <br />the Geotechnical Report by Landau Associates. These documents can be found in Appendix C. <br />Riverside Business Park — Port of Everett <br />5 <br />
