Local Wetland Inventories
Local Wetlands Inventories (LWIs) are comprehensive maps and information about wetlands throughout a city. An LWI provides information a city needs to incorporate wetlands and streams into their comprehensive plans for the community.
The LWIs replace the National Wetlands Inventory (NWI) in urban areas.
In 1990, DSL adopted guidelines and rules for conducting LWIs within urban growth boundaries.
The LWI rules were updated in February 2001 and in January 2009.
LWIs are conducted by wetlands consultants for cities completing wetlands planning under Statewide Goals 5 (Natural Resources) or 17 (Coastal S​​horelands). LWIs or other resource inventories for areas outside of Urban Growth Boundaries (UGBs) have been completed for other planning goals or purposes.
Wetlands program staff work closely with cities and consultants to ensure that the LWIs are thorough and conducted according to standards. 
LWIs may be viewed at the local planning department, at the Department, or on this Web site.  Access the LWIs by reading and accepting the disclaimer at the link below.
