Wetland delineation is the process of identifying and mapping the boundary of areas that meet applicable wetland criteria. It typically considers vegetation, soils, and hydrology, using the methods required by the relevant authority. Boundaries may require agency confirmation. A delineation reflects field conditions and methods at a particular time and has stated limits.
Why it matters for owners
Delineation can affect site planning, permits, access, and project alternatives. Confirm review and jurisdictional steps early.
