Wisconsin
Industrial Stormwater Permit Compliance
Industrial stormwater SWPPPs, monitoring and corrective action under EPA's Multi-Sector General Permit or state permits.
What the work involves
Many industrial facilities must obtain stormwater permit coverage, prepare a facility SWPPP, monitor discharges and take corrective action when benchmarks are exceeded. Engineers design structural controls such as covers, berms and treatment devices when good housekeeping alone does not meet requirements.
Local conditions we plan for
- Deep frost penetration
- Heavy snow loads
- Great Lakes shoreline erosion
- Karst in the southwest Driftless Area and Door County
Building code: IBC 2021 statewide for commercial buildings; one and two family dwellings use the state Uniform Dwelling Code instead of the IRC (ICC adoption chart, April 2026).
When you need it
- Facility in a regulated industrial sector
- Benchmark exceedances
- Agency inspection findings
- New facility or expansion
Frequently asked questions
How much does industrial Stormwater Permit Compliance cost?
Across the US, industrial Stormwater Permit Compliance usually costs $2,000 to $25,000 per facility. Estimate. Plan updates are modest; structural controls and treatment design cost more.
How long does industrial Stormwater Permit Compliance take?
Plan on 2 to 8 weeks from signed proposal to stamped deliverables, longer if a site visit, soil testing or a permit review cycle is involved.
Do I need a licensed PE for industrial Stormwater Permit Compliance?
In most US jurisdictions, yes. When the work needs a permit, the plans, calculations or report usually must be sealed by a Professional Engineer licensed in the state where the project is located. Every deliverable we issue for permit is sealed that way.
How do I verify an engineer's license in Wisconsin?
Engineers practicing in Wisconsin are licensed by the Wisconsin Examining Board of Architects, Landscape Architects, Professional Engineers, Designers and Professional Land Surveyors. You can confirm a license number and its status in the board's public license search before you sign a contract.
How deep is the frost line in Wisconsin?
Wisconsin Uniform Dwelling Code SPS 321.16 requires footings to be below frost penetration or at least 48 inches below adjacent grade, whichever is deeper (one and two family dwellings). Local building departments set the required footing depth, so confirm the exact figure for your county before designing foundations or retaining walls.
Which building code applies in Wisconsin?
IBC 2021 statewide for commercial buildings; one and two family dwellings use the state Uniform Dwelling Code instead of the IRC (ICC adoption chart, April 2026). Cities and counties can add local amendments, which is one reason to hire an engineer who works in your area.
