Description: All wetlands greater than or equal to one half of an acre and all wetlands identified in a Department-approved wetland delineation report are required to be identified and mapped as polygons with a goal accuracy of +/- 5 meters (under 2009 LWI rules, prior goal was +/-25 feet).Wetland polygons are associated with wetland functional assessment results and wetland summary sheets found within the LWI report. Wetland polygons include required attributes including unique wetland identification label, Cowardin classification code(s) and modifiers, HGM classification, approximate wetland size, Locally Significant Wetland significance determination, whether it was onsite, offsite or visually confirmed, and the Department's wetland delineation report file number, if any.In December 2024, SWCA completed a delineation for Kingston Terrace South for THNC Oregon, LLC. The SCWA report (SWCA 2024) includes a small portion of the Kingston Terrace East LWI area along SW Elsner road. SWCA and THNC Oregon, LLC generously provided data plots and linework to further refine DEA’s estimated boundaries, and these boundaries are included in the KTE LWI.

Description: Waterways, for example rivers and streams. Waterways will trigger cities and counties to notify the Department of proposed land use activities affecting mapped wetlands and waters (ORS 215.418 and 227.350).

Description: "Probable Wetland" or “PW” means an area noted during LWI development that appears to meet wetland criteria but is less than one half of an acre in size or is small and of undetermined size. Wetlands that are less than one half of an acre may be mapped as polygons or as probable wetlands. Probable wetlands represented as polygons on the appropriate parcel(s) and should be labeled as "PW” on the maps. No further characterization or assessment is required for probable wetlands in the LWI. Probable wetlands will trigger cities and counties to notify the Department of proposed land use activities affecting mapped wetlands and waters (ORS 215.418 and 227.350).

Description: This layer shows the extent of human-made or modified aquatic features. Note – “Artificial Feature” does not imply that a feature is non-jurisdictional. Artificially created wetlands or other waters (such as irrigation canals and drains, industrial ponds, log ponds, golf course features, and storm water detention ponds that are greater than one half of an acre in size) are required to be included in the inventory regardless of their jurisdictional status, and their original purpose must be labeled on the inventory maps. Wetlands and waters will trigger cities and counties to notify the Department of proposed land use activities affecting mapped wetlands and other waters (ORS 215.418 and 227.350).

Description: All waterbodies that are best represented by polygons rather than lines, for example larger rivers, ponds, lakes, or the ocean.Waterbodies will trigger cities and counties to notify the Department of proposed land use activities affecting mapped wetlands and waters (ORS 215.418 and 227.350).

Description: Watershed boundaries as defined and mapped in the LWI when smaller than HUC-12 watersheds were determined and outlined for the LWI study area. This feature class may be more appropriate than the USGS HUC-12 watersheds for smaller study areas.

Description: "Probable Wetland" or “PW” means an area noted during LWI development that appears to meet wetland criteria but is less than one half of an acre in size or is small and of undetermined size. Wetlands that are less than one half of an acre may be mapped as a probable wetland polygon or point. Probable wetlands represented as points on the appropriate parcel(s) should be labeled as "PW” on the maps. No further characterization or assessment is required for probable wetlands in the LWI. Probable wetlands will trigger cities and counties to notify the Department of proposed land use activities affecting mapped wetlands and waters (ORS 215.418 and 227.350).

Description: "Sample Plot" means a specific area on the ground where soils, vegetation and hydrology data are recorded on a field data form, per DSL Division 90 Rules, to make a wetland determination.141-090-0020 (30) "Sample Plot" means an area on a parcel of land within which environmental data (e.g., soils, hydrology and vegetation) are collected that is representative of that area and documented on a wetland determination data form.
