Erosion and Sediment Control Plan
Erosion and sediment control drawings for grading permits, showing silt fence, inlet protection, stabilization and phasing.
What the work involves
Most grading and building permits that disturb soil require an erosion and sediment control plan. The engineer locates silt fence, construction entrances, inlet protection, sediment traps or basins, slope protection and stabilization measures, and phases them with grading. On sites under the 1 acre federal threshold, local ordinances often still require these plans.
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
- Grading or building permit that disturbs soil
- Work near streams, wetlands or storm drains
- Steep slopes with erosion risk
- Inspector issued an erosion control violation
Frequently asked questions
How much does erosion and Sediment Control Plan cost?
Across the US, erosion and Sediment Control Plan usually costs $500 to $8,000. Estimate. Often bundled with grading or site plans.
How long does erosion and Sediment Control Plan take?
Plan on 1 to 3 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 erosion and Sediment Control Plan?
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.
