Grading and drainage in Wayne County require local building permits, SESC compliance under MCL 324.9101, and coordination with the Wayne County Drain Commissioner for county drains.
Grading and drainage work on residential and commercial property in Wayne County is governed by municipal building codes, Michigan's Soil Erosion and Sedimentation Control program (Part 91, MCL 324.9101), and the Michigan Drain Code of 1956 (MCL 280.1 et seq.). Building permits from the city or township are generally required for regrading that alters drainage patterns, retaining walls over 4 feet, or work affecting neighboring properties. Michigan follows the reasonable-use rule for surface water drainage: landowners cannot unreasonably increase runoff onto neighbors. County drains (open channels, enclosed drains, and drainage districts) are managed by the Wayne County Office of the Water Resources Commissioner, which permits connections and alterations. Homeowners must not fill, obstruct, or connect to county drains without permission. Violations can result in orders to restore drainage and liability for damages. Contact the Water Resources Commissioner at (313) 224-3620 before any work near a county drain.
