Description:
Abstract:
The shapefile displays those basins within which development projects qualify for using the existing land cover condition as the stormwater flow control default target. This is a lower flow control default target than the target used for most of western Washington, which is based upon use of the historic land cover condition.
Purpose:
The Western Washington Stormwater Mangement Manual allows local governments to adopt a flow control standard that requires land development projects to match high flow durations that are produced by the existing land cover condition. As pre-requisite to allowing that standard, the manual recommends that the drainage area of the immediate stream and all subsequent downstream basins must have had at least 40% total impervious area since 1985. To help implement this option, the Department of Ecology has produced a map that displays the basins in western Washington within which development projects qualify for this lower flow control standard.
Supplemental_Information:
The state of the data set: The Department of Ecology contracted with NOAA Coastal Services Center to interpret satellite images for purposes of providing impervious area data for western Washington for 1986. In regard to the underlying data set for the map, the Department does not have any plans to make alterations to the existing data. The Department also has not made any commitments to update the land cover analysis to represent a more recent land cover condition. Time Period for which the data is relevant: The production of the map relied on interpretation of satellite images taken between 20020819 and 20020906.

Process_Description:
Ecology contracted with NOAA Coastal Services Center to provide 1986 impervious area land cover data for western Washington for 1986. Ecology used the 1986 total impervious area estimates by basin from NOAA to determine which areas qualify for use of the existing land cover condition as the flow control target for new and redevelopment projects. For the Basins_1986 Criterion.shp file, we computed an area weighted average by basin based upon Shape_Area and Imp_1986. If weighted average >40%, then use existing land cover; If weighted average < 40% TIA, basin does not qualify for less stringent flow control standard.
