Name: DrainageArea_Clip

Display Field: ProjectName

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN><SPAN>This feature class contains WSDOT’s stormwater drainage areas. A drainage area is the </SPAN></SPAN><SPAN><SPAN>land surface area contributing runoff to a specific point in the stormwater system. This is determined as the sum of the total land surface area upstream from the point being analyzed and does not include areas within the polygon that are known to be or seen to be noncontributing to surface runoff. A drainage area is determined from local topographic maps and designed perimeter-confining features (e.g., curbs, concrete barriers, roadway crown, and designed gradient inflection lines in paved surfaces). It may have several different parts, respective to the impervious cover, soil, and vegetative ground cover types within the polygon.</SPAN></SPAN><SPAN><SPAN>The majority of the data collected so far are within the Phase I and Phase II 2009 NPDES Municipal Stormwater Permit Areas.</SPAN></SPAN></P></DIV></DIV></DIV>
