Wyoming, MI Environmental Rules: Stormwater Management (2026)

Section 68-21 of the Stormwater Ordinance, adopted by Ordinance No. 2-22 effective January 17, 2022, states that no person may begin or engage in any development in Wyoming, Michigan without first obtaining stormwater review and approval, and that any approval granted covers only the discharge authorized by that specific site plan, parking lot plan or plat. To get approval, Section 68-22 requires a developer to submit a drainage plan meeting the city's Stormwater Standards Manual, pay all review costs charged by the city engineer under Section 68-24, and, where required, post a performance guarantee such as an irrevocable letter of credit under Section 68-26 and record a maintenance agreement under Section 68-73.

No final certificate of occupancy can issue under Section 68-27 until the approved stormwater facilities are complete, unless an acceptable letter of credit is in place. Once built, Section 68-31 puts ongoing responsibility on the property owner: the city is not obligated to provide or maintain drainage facilities on private property, and the owner must maintain private stormwater management facilities and clear any debris that blocks drainage function. The ordinance draws its authority from the Home Rule City Act, the Drain Code of 1956, and the federal Clean Water Act's NPDES stormwater program under 33 USC 1342(p), reflecting that Wyoming operates its own MS4 permit within Kent County.

Enforcement runs through the city engineer's office, which can issue stop work orders under Section 68-62 and refer repeat or serious violations for municipal civil infraction citations.
