This feature class contains WSDOT\u2019s stormwater dispersion areas. A dispersion area is a <\/SPAN><\/SPAN>natural or engineered feature where stormwater is spread over a wide area and is located so as not to allow flow to concentrate anywhere upstream of a drainage channel with erodible underlying granular soils. A dispersion area must meet the requirements of BMP FC.01.1 (natural dispersion) or FC.02.01 (engineered dispersion) from the <\/SPAN><\/SPAN>Highway Runoff Manual<\/SPAN><\/SPAN><\/A>. It must also be included in an as-built plan sheet as an indication that it has been approved for use as a best management practice (BMP) for a particular location.<\/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>", "summary": "The Stormwater Features Inventory Database (SFID) was developed in response to WSDOT\u2019s 2009 NPDES Municipal Stormwater Permit, issued by the Washington State Department of Ecology.
