Summary

Wayne County requires a stormwater construction approval and construction permit before any regulated construction activity affecting county roads, county drains, county property, or county storm sewer systems, enforced with civil-infraction fines starting at $1,000.

City-specific rules exist: Westland, Detroit, Dearborn, and Livonia have their own stormwater management rules that differ from Wayne County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

It shall be a violation of this Ordinance to engage in regulated construction activity except in accordance with this Ordinance and rules promulgated pursuant to this Ordinance, and pursuant to a valid stormwater construction approval and construction permit issued by the County. A stormwater construction approval shall be issued in a form and manner approved by the County and may be incorporated into a construction permit or other approval issued under or required by another ordinance, statute or regulation.

Full Breakdown

Under the Wayne County Stormwater Control Ordinance, administered by the Department of Public Services, construction activity that may affect stormwater runoff into county road rights-of-way, county drains, county-owned property, or county storm sewers needs a stormwater construction approval and construction permit before work starts, plus a long-term maintenance permit recorded against the property once the system is built. The county steps back where a local city or township within Wayne County already runs its own stormwater program that is equal to or stricter than the county's minimum requirements (§ 95-32).

Violations & Fines

Civil infraction: $1,000 per violation, rising to $2,500 for a first repeat and $5,000 for later repeats within 12 months; unpaid fines double after 28 days. Knowing false statements to the county are a misdemeanor: up to $500 per day plus 90 days in jail (§§ 95-96, 95-98).

Frequently Asked Questions

Does this county ordinance apply inside cities like Dearborn or Livonia?
Only to activity affecting county roads, county drains, county property, or county storm sewers; a local government whose own stormwater program is equal or stricter controls instead (§ 95-32).
What happens if I build without the county stormwater permit?
A $1,000 civil infraction fine per violation, doubling if unpaid after 28 days, with repeat offenses reaching $5,000 and possible misdemeanor charges of up to $500/day and 90 days in jail.
