Wetland boundary delineation

Determining wetland boundaries

Anyone planning a development project must know precisely the boundaries of wetlands on the property as determined through procedures specified in state and federal rules. A wetland professional is generally required to make the boundary determination and their findings are subject to review by regulatory agencies.

All determinations must follow the requirements specified in these documents:

Wisconsin Wetlands 1987 COE Manual
  1. Chapter NR 103, Wis. Adm. Code
  2. Chapter NR 352, Wis. Adm. Code
  3. The 1987 U.S. Army Corps of Engineers Wetland Delineation Manual [PDF exit DNR]
  4. The proper U.S. Army Corps of Engineers Regional Supplement for your location.

Wetland delineation classes

Each year the University of Wisconsin–La Crosse holds wetland delineation workshops. These two–and–a–half day workshops are held in La Crosse and at an alternate location in Wisconsin that changes each year. The courses are taught by experts and will be of interest to anyone who delineates wetlands or wishes to learn how to delineate wetlands in Wisconsin.

Wetland delineation professional assurance

DNR has established a professional assurance program for those highly experienced professional wetland consultants that meet certain qualifications. Professional assurance means that the work of individuals meeting training and performance standards will receive spot checks rather than individual review. This should result in faster decisions and improved wetlands protection. For information and instructions, refer to:
Wetland delineation professional assurance initiative.
