Some local governments must inventory and include protections for resources listed in Oregon\u2019s land use planning goals 5 (Natural Resources), 16 (Estuaries) and 17 (Coastal Shorelands). DSL is responsible for the requirements and review of LWIs for Goal compliance and other natural resource planning efforts. DSL works with local governments and the Department of Land Conservation and Development (DLCD) to provide both technical and planning assistance to local governments that are completing inventories and other related tasks.<\/p>
In accordance with the DSL\u2019s LWI standards, the approximate location and boundaries of all wetlands at least 0.5 acre in size, and waters are identified within a specified study area. LWIs developed after 2001 also included \u201cprobable wetlands\u201d (\u201cPW\u201d) to indicate locations of wetlands and waters less than one-half acre in size.<\/p>
Upon approval by DSL, the LWI must be used in lieu of the National Wetlands Inventory (NWI) and is incorporated into the SWI. The approved LWI must be used by cities and counties in lieu of the NWI for notifying DSL of land use applications affecting mapped wetlands and other waters (ORS 215.418 and 227.350). An LWI fulfills the wetlands inventory requirements for Goal 5 and Goal 17 (OAR 660-015, 660-016, and 660-023).<\/p>
Some information, like observed plant species, originally provided on LWI maps by some local governments and consultants may not be included in the LWI_Statewide dataset. See the original approved maps and reports on the DSL LWI web page.<\/p>
Further information on the development and results of individual LWIs is contained in the LWI reports, original maps, and individual GIS datasets, is available for view and download from the DSL LWI web page. The LWI GIS Data Description and template is available on the DSL LWI web page.<\/p>", "mapName": "SWIStatewideLWILayers", "description": "Some local governments must inventory and include protections for resources listed in Oregon\u2019s land use planning goals 5 (Natural Resources), 16 (Estuaries) and 17 (Coastal Shorelands).
