The Stormwater Features Inventory Database (SFID) was developed in response to WSDOT’s 2009 NPDES Municipal Stormwater Permit, issued by the Washington State Department of Ecology. Among other elements, the permit requires WSDOT to maintain an ongoing storm sewer system mapping program for areas within the permit’s jurisdictional boundaries. |

<DIV STYLE="text-align:Left;"><DIV><P><SPAN>This is a view of the ArtificialPath featureclass created with the following query: WHERE LifeCycleCurrentStatus= 'Active' AND (WSDOTownership in ('Yes', 'Unknown') OR WSDOTownership IS NULL) AND SWLocationVerified = 'Yes' This feature class contains WSDOT’s stormwater artificial paths. An artificial path is used to represent flow through a dispersion area, roadside slope polygon, or stormwater pond polygon when there is no other conveyance feature from the inlet to outlet structure. It is also used for areas where stormwater flow is briefly dispersed to sheet flow from the end of a conveyance and then concentrated again by another downstream conveyance prior to discharge. These paths are important for maintaining connectivity of the stormwater system GIS model. The majority of the data collected so far are within the Phase I and Phase II 2009 NPDES Municipal Stormwater Permit Areas.</SPAN></P></DIV></DIV> |
