Clinton Township, MI Environmental Rules: Erosion Control (2026)

Clinton Township folds erosion control into Chapter 1248, the township's Engineering and Construction Standards, adopted by Ord. 481 on October 24, 2022. 03 governs site grading and storm water drainage for every land development project, and subsection (f) requires soil erosion and sedimentation control measures to be shown on the engineering plans and actually maintained while grading and construction are underway, not merely promised on paper. The requirement is tied directly to Michigan's Natural Resources and Environmental Protection Act, Act 451 of 1994, and the code names the Macomb County Public Works Office, not the Township Building Department, as the agency that issues the underlying soil erosion permit.

That permit sits alongside the Township's own site-grading approval: subsection (b) requires a site grading and drainage plan for nearly every development, and subsection (c) bars anyone from obstructing or altering approved drainage flow across a property. Before a certificate of occupancy issues, the Township Engineer must approve final site grading and drainage, and a registered engineer or surveyor must certify the graded site matches the approved plan. Developers working through winter can get a temporary certificate of occupancy if grading is weather-delayed, but only against a bond, letter of credit or cash deposit guaranteeing the outstanding work gets finished.

Because the erosion-control permit itself runs through the county rather than the township, a builder needs sign-off from both Macomb County Public Works and the Clinton Township Engineer before site work can proceed to occupancy.
