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 ConcreteBarrier 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 concrete barriers.Stormwater concrete barriers are barriers or walls, such as single-slope or K-barriers, which concentrate and convey stormwater flows, even if they were not designed or installed with the primary intent of being a conveyance. This feature class only contains concrete barrier segments actively concentrating and conveying stormwater flows (i.e., a barrier located at the high side of a super-elevated roadway will not concentrate and convey stormwater flows and therefore will not be mapped). 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> |
