How Farmington Hills Handles Environmental Rules: A Practical Guide
Farmington Hills maintains 60 local ordinances across all categories, and 5 of those deal specifically with environmental rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Farmington Hills falls on the strict-to-permissive spectrum compared to other cities.
Vehicle Idling Restrictions
Farmington Hills bars a parked or standing commercial truck or tractor-trailer from running its engine audibly on adjacent residential property for more than 20 minutes while loading, unloading or waiting to do so. Section 17-101(e)(2) treats this as a noise violation independent of the decibel table.
Key details: Governing section: City Code § 17-101(e)(2). Idling limit: 20 minutes while loading/unloading/waiting. Applies to: Parked/standing commercial trucks, tractor-trailers. Trigger: Audible on adjacent residential property. Penalty: Municipal civil infraction (§ 17-107).
Running a parked or standing commercial truck or tractor-trailer's engine audibly on neighboring residential property for more than 20 minutes while loading, unloading or waiting is a municipal civil infraction under Section 17-107, citable even if the sound level stays under the Table A decibel cap for the district.
Flood Elevation Requirements
Farmington Hills requires one foot of freeboard above the 100-year stormwater elevation in every detention and retention basin, under the Stormwater Engineering Design Standards adopted by City Code Sec. 33-320 (Appendix B). A 0.5-foot buffer must separate the 100-year storage elevation from the emergency overflow spillway, and the primary overflow structure's rim must sit at the 100-year storm elevation.
Key details: Freeboard requirement: 1 foot above 100-year stormwater elevation. Spillway buffer: 0.5 feet to emergency overflow spillway. Bridge freeboard: 2-foot minimum, 100-year flood stage. Adopted by: City Code §33-320 (Appendix B). Reviewing agency: Oakland County Water Resources Commissioner.
A detention or retention basin that does not meet the one-foot freeboard, 0.5-foot spillway buffer, or overflow-structure rim elevation will not clear Water Resources Commissioner review of the construction plans, which is a prerequisite to final plat and subdivision approval in Farmington Hills. The WRC also withholds final project acceptance until all storm water detention and retention facilities and forebays are constructed and stabilized as approved.
Flood Zones
Farmington Hills regulates floodprone land by adopting FEMA's 2006 Oakland County Flood Insurance Study and its Flood Insurance Rate Maps directly into the Michigan Building Code it enforces. Development within a mapped special flood hazard area must meet the construction-code flood provisions the city administers.
Key details: Source maps: 2006 FEMA Flood Insurance Study, Oakland County. Adopted into: Michigan Building Code § 1612.3. FIRM panels: 13 panels listed, e.g. 26125C489F. Enforcing agency: Building official, city engineer, inspectors, board of appeals. Chapter 13 status: Flood Damage Prevention chapter repealed in full.
Sec. 7-30 does not carry its own penalty clause; building within a designated floodprone hazard area without complying with the Michigan Building Code's Section 1612.3 flood provisions is enforced as a State Construction Code violation, handled through the same building-permit and inspection process, and the building board of appeals, that the city and its designated inspectors use to administer construction codes citywide under Sec. 7-26.
Erosion Control
Farmington Hills requires soil erosion and sediment control devices on every site under construction, per the Stormwater Engineering Design Standards the city adopted by reference in Sec. 33-320 (Appendix B). Projects need a soil erosion and sedimentation control permit under Part 91 of Act 451, and the Oakland County Water Resources Commissioner administers the program and enforces its 'Erosion Control Manual' for city sites.
Key details: Governing standard: Appendix B, Stormwater Engineering Design Standards. Adopted by: City Code §33-320. Administering agency: Oakland County Water Resources Commissioner. Required permit: Soil erosion & sedimentation control permit (Act 451, Part 91). Reference manual: WRC 'Erosion Control Manual'.
Failure to install or maintain required erosion and sediment control devices blocks project approval: the Water Resources Commissioner will not grant final construction plan acceptance while outstanding soil erosion issues or a history of poor practices remain, and application or inspection deposits are forfeited if erosion control work is not completed as approved. Operating without the Part 91 soil erosion and sedimentation control permit also exposes a developer to enforcement under the state Natural Resources and Environmental Protection Act.
Stormwater Management
Farmington Hills bans discharging anything but stormwater into its municipal storm drain system under the city's illicit discharge elimination program. City Code Sec. 33-306 prohibits illegal discharges, illicit connections, and direct dumping into the storm sewer, with narrow exemptions like firefighting water and dechlorinated single-family pool water. The Department of Public Services enforces the article, and violations are municipal civil infractions under Sec. 1-24.
Key details: Governing law: Ch. 33, Art. IX, Div. 1 (§§33-300–33-315). Enforcing agency: Dept. of Public Services / code enforcement. Penalty: Municipal civil infraction under §1-24. Spill reporting deadline: Next business day (non-hazardous). Record retention: At least 3 years on-site.
The director of public services may issue a notice of violation requiring monitoring, elimination of illicit connections, cessation of the violating discharge, abatement or restoration of affected property, a fine covering administrative and remediation costs, and BMP installation (Sec. 33-313). Missing the compliance deadline lets the city issue a municipal civil infraction citation under Sec. 1-24 or sue in district court; if the city completes abatement itself, unpaid costs become a special assessment lien collected on the delinquent tax roll (Sec. 33-314).
The Bottom Line
Farmington Hills's environmental rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Farmington Hills is broadly strict or permissive.
