Civil Engineering in Wisconsin: what governs your project

Construction stormwater discharges are regulated by the Wisconsin Department of Natural Resources through the Wisconsin Pollutant Discharge Elimination System (WPDES) construction general permit. Connections to state highways require access permits from the Wisconsin Department of Transportation. Wisconsin has strong wetland and waterway protections, and earthwork is seasonally constrained by frozen ground and spring thaw conditions.

Permitting & plan check

The Department of Safety and Professional Services reviews commercial building plans at the state level for many municipalities, while larger cities operate delegated plan review programs. Building permits are issued locally under the Wisconsin Commercial Building Code. Designers should verify whether a project falls under state or delegated municipal review early in the process.

Good to know

• Wisconsin's frost penetration runs deep, so building foundations and footings must extend well below grade to get beneath the frost line.
• Northern and lake-effect regions of Wisconsin see some of the heaviest snow loads in the Midwest, making roof snow design a controlling case.
• Wisconsin's commercial building plan review is handled at the state level by the Department of Safety and Professional Services for many project types.

Every discipline, one team
