Wetland tools & other resources
We provide technical assistance and develop tools for the management, regulation, and stewardship of wetlands.
Best available science - A two-volume document on the science available on wetlands, their functions and management.
Calculating credits and debits for compensatory mitigation (Credit/Debit tool) - A tool for calculating when a proposed wetland mitigation project adequately replaces the functions and values lost when wetlands are impacted.
National Wetland Condition Assessment - Information about a national survey of ecological condition of the Nation's wetlands.
Voluntary Stewardship Program (VSP) - Provides electronic data and information, including links to wetland mapping resources, to support counties that under planning under the Washington Voluntary Stewardship Program (VSP).
Watershed characterization and landscape planning - A tool for including watershed condition in the planning process. Watershed characterization information can help identify areas that are more appropriate for wetland restoration and mitigation. Links to examples and guidance are provided.
Wetland delineation resources - Wetland delineation establishes the existence (location) and physical limits (size) of a wetland for the purposes of federal, state, and local regulations.
Wetland inventory map for Western Washington - This 2011 medium-resolution scale map can be used to look for wetlands in your area. It was developed by us and NOAA modeled from NOAA's Coastal Change Analysis Program.
Wetland program plan - In March 2015, we and the Interagency Work Group finalized the state's Wetland Program Plan. The plan is a strategic tool, developed and implemented by the state, to articulate what the state seeks to accomplish wit the wetland program over time.
Wetland rating systems - A method that categorizes wetlands into four categories based on their sensitivity to disturbance, their rarity, our ability to replace them, and the functions they provide. Some decisions that can be made based on the rating include the width of buffers needed to protect the wetland from adjacent development, the amount of mitigation needed to compensate for impacts to the wetland, and permitted uses in the wetland.
