Freshwater Wetlands Jurisdiction
Once the map viewer loads click on the “Boundaries and Regulatory Overlays” layer and then choose “Wetland Jurisdiction”

(The CRMC and RIDEM collaborated on this legislatively-directed project that establishes clear delineations for the jurisdictional areas for freshwater wetlands. If your project lies on one side of the jurisdiction line, then you only need one agency to review the project.)
