Topic - Storm Water Management

Generally, the Wisconsin Department of Commerce (COMMERCE) is granted erosion control authority over commerial building (Wis. Stats. Chapter 283 [PDF exit DNR]). Federal and state law requires that your business obtain permit coverage before initial land disturbing activity occurs if the project will result in 1 or more acres of land disturbance (1 acre = approx 210 feet by 210 feet of land area).

NOTE: If your proposed facility is near surface waters or wetlands you may also need a DNR Waterway and Wetlands permit. Please refer to the pop-up link, Waterway and Wetland Permits for more information. If your development proposes a large scale parking area or parking structure, an indirect source air permit may be required priot to construction. Please refer to the Indirect Source Permit Application for more information.

To determine what permits and approvals may be required, please contact a Department of Commerce staffperson(s) [exit DNR]. After you visit the Commerce web site, please select the appropriate button (below) to determine if you need an operational storm water permit.
