Title
SMA Jurisdiction Original WAC173 18 Points [Washington (State)]
Description
Streams and rivers published in Chapter 173-18-WAC. This layer will not be updated. It is slowly becoming outdated as cities and counties update their list of Shoreline Management Act streams in their shoreline master program. See WAC 173-18-044 posted at http://apps.leg.wa.gov/wac/default.aspx?cite=173-18-044.The upstream points where SMA jurisdiction begins were originally compiled for Ecology in 1972 by the US Geological Survey, Water Resources Division, Tacoma, WA, and released in STREAMS OF WASHINGTON UNDER THE REQUIREMENTS OF THE SHORELINE MANAGEMENT ACT OF 1971. Points were determined using multiple-regression techniques based on streamflow and basin precipitation records. Ecology has occasionally updated those points and added and subtracted SMA streams and portions of SMA streams since 1972.
