• <br /> 4 <br /> Existing structures: None <br /> Landscape Topogra- Bare soil and quarry spalls. Flat to gently <br /> phy: sloped and undulating. <br /> The site is largely flat. Localized depres- <br /> Drainagepatterns: sions may allow minor ponding. A gentle <br /> slope to the east exists in some portions of <br /> the site. <br /> Existing Vegetation: Mostly unvegetated, with some grasses and <br /> shrubs around the edges of the site. <br /> Critical Areas(wet- <br /> lands, streams,high <br /> erosion risk, steep or None <br /> difficult to stabilize <br /> slopes): <br /> OFF-SITE ANALYSIS AND MITIGATION <br /> Upon completion of the excavation and backfilling, no hard or impervious surfaces will exist on <br /> site and any potential for pollution will have been removed. <br /> UPSTREAM AND DOWNSTREAM ANALYSIS <br /> Due to the flat nature of the site and its high infiltration capacity, flow from or onto adjacent <br /> properties is negligible. <br /> MR 2 - STORMWATER POLLUTION PREVENTION PLAN <br /> The Stormwater Pollution Prevention Plan (SWPPP) is provided as a separate document (PGG <br /> 2019b). <br /> MR 3 — WATER POLLUTION SOURCE CONTROL <br /> Upon completion of the cleanup as described in the CAP (PGG 2019a) there will be no ongoing <br /> sources of potential pollution on the site. Source Control Best Management Practices(BMPs)that <br /> will be used during construction are described in the SWPPP(PGG 2019b). <br /> Everett Steel Stormwater Site Plan and Drainage Report 2 T <br /> AUGUST 2019 PgG <br />
