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 Pipes featureclass created with the following query: PipeType = 3 AND LifeCycleCurrentStatus= 'Active' AND (WSDOTownership in ('Yes', 'Unknown') OR WSDOTownership IS NULL) AND (SWLocationVerified IS NULL OR SWLocationVerified = 'No') This feature class contains WSDOT’s stormwater pipe ends. A pipe end is the end point of a pipe, which is a sub-linear enclosed conveyance designed and constructed to convey flow; it has a clear opening of less than 20 feet (see Hydraulics Manual, Chapter 8). The majority of the data collected so far are within the Phase I and Phase II 2009 NPDES Municipal Stormwater Permit Areas. This feature class has six subtypes: Culvert Pipe, Drain Pipe, Sanitary Sewer Pipe, Storm Sewer Pipe, Underdrain Pipe, and Unknown.</SPAN></P></DIV></DIV> |
