Do I need a permit to bring in fill dirt?
Most municipalities require a grading permit for significant fill or grading operations. Small quantities for gardening are usually exempt.
What about erosion control?
Sites disturbing more than 4,000 sq ft (some municipalities set lower thresholds) typically require erosion control measures. DNR permits may be needed for sites over 1 acre.
Can I fill a wetland on my property?
No. Filling wetlands requires federal Army Corps of Engineers and state DNR permits, which are rarely granted for private development. Wetland boundaries must be delineated before any nearby construction.
