This service consists of a written statement, based upon an on-site inspection, of whether the DNR agrees with the wetland boundaries delineated by a consultant. A fee of $300 per 20 acres of land reviewed is associated with this service, and requesters will receive a response in 60 days or less.
The goal of this service is to provide landowners and developers certainty that a project’s delineated wetland boundaries are accurate before project plans are finalized. Taking advantage of this service early in the planning phase will prevent unexpected wetland boundary concerns from delaying a project’s approval.

Artificial wetland exemptions
Some artificially created wetlands are exempt from state wetland laws. These exemptions are specifically for:
- Sedimentation and storm water detention basins and associated conveyance features operated and maintained only for flood storage purposes.
- Active sewage lagoons, cooling ponds, waste disposal pits, fish rearing ponds and landscape ponds.
- Actively maintained farm drainage and roadside ditches.
- Artificial wetlands within active nonmetallic mining operations.
To see if a wetland qualifies for exempt status, refer to this information sheet [PDF].
