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 FlowRestrictor featureclass created with the following query: 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 flow restrictors. A flow restrictor is a device such as an orifice or weir that restricts the volume of stormwater flow through or at the outlet of a structure. It may be associated with a “control structure” as part of a “flow restrictor system” (see Standard Plans B-10.40, B-10.60). 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> |
