Service Description:

Local Wetlands Inventory development requires a GIS dataset displaying all wetlands greater than or equal to one-half of an acre in size, and all wetlands identified in DSL-approved wetland delineation reports, to be mapped as polygons with a goal accuracy of +/- 5 meters (under 2009 LWI rules). LWIs developed prior to 2001 did not require mapping of wetlands less than one half acre in size. After 2001 mapping of “Probable Wetland" or “PW” is required for wetlands less than one half of an acre in size. There may be unmapped wetlands within the study areas of all LWIs, particularly older inventories.

LWI wetland polygons are associated with wetland functional assessment results and wetland summary sheets, found within the LWI report. Upon approval by DSL the LWI must be used in lieu of the National Wetlands Inventory (NWI), fulfills the wetlands inventory requirements for Goal 5 and Goal 17 (OAR 660-015, 660-016, and 660-023), and is incorporated into the Statewide Wetlands Inventory. The approved LWI must be used by cities and counties for notifying DSL of land use applications affecting mapped wetlands and other waters in the wetland land use notice (WLUN) process (ORS 215.418 and 227.350).

The digitizing and standardization of LWI GIS datasets approved by DSL prior to 2018 has been funded wholly or in part by the United States Environmental Protection Agency under assistance agreement number CD-01J37701-02 to DSL. The contents of this LWI dataset do not necessarily reflect the views and policies of the Environmental Protection Agency, nor does mention of trade names or commercial products constitute endorsement or recommendation for use.
