SSS/SMA Streams and Rivers Constituting Shorelines of the State


The Shorelines of Statewide Significance (SSS) depict points on a stream where water flow reaches 1000 cubic feet per second (cfs.) The Shoreline Management Act (SMA) points denote the stream location where water flow reaches 20 cubic feet per second. This is the point where the stream falls under SMA jurisdiction (WAC173-25 & RCW 90.58.) This project involves the conversion of these point coverages into point and linear events associated to the draft 1:100,000 Framework Hydrography set. A tabular listing any SSS by name, county, or WRIA and the calculated length of stream miles of all SMA & SSS streams by type (20 and 100 cfs) will be generated and well as 1:24,000 quadrangles depicting general thematic data along with surface hydrography and SSS/SMA point/linear events.

These newly created events will assist governmental organizations and the public in administering and complying with the Shoreline Management Act.
