| Short Description |
This document was Washington State's official manual for delineating wetlands. Delineation manuals are used to determine the edge of a wetland based on three "parameters": water, plants, and soil. As of March 14, 2011 this manual is no longer valid. Delineations should be done according to the currently approved federal manual and supplements. See RELATED WEB CONTENT for more information.

| Abstract | Long Description |
State laws require that wetlands protected under the Growth Management Act and the Shoreline Management Act be delineated using a manual that is developed by Ecology and adopted into rules (RCW 36.70A.175; RCW 90.58.380). The Department of Ecology adopted this wetland delineation manual in 1997 (WAC 173-22-080) that was based on the original 1987 Corps of Engineers manual and subsequent Regulatory Guidance Letters. During the last few years the Army Corps of Engineers has updated and expanded their delineation manual with regional supplements. To maintain consistency between the state and federal delineations of wetlands, Ecology has repealed WAC 173-22-080 (the state delineation manual) and replaced it with a revision of WAC 173-22-035 that states delineations should be done according to the currently approved federal manual and supplements. The changes became effective March 14, 2011. Thus, starting on March 14, 2011, the latest federal delineation manual and its supplements should be used to delineate wetlands in the state. |
