Farmington Hills, MI Tree Protection: Heritage & Protected Trees (2026)

Farmington Hills' tree-protection framework does not include a separate heritage-tree, landmark-tree, or champion-tree designation. Instead, the citywide 6-inch DBH permit trigger under Chapter 34-5.18 functions as a broad protection covering all mature trees on private property — a structurally different approach from cities like Honolulu or Pasadena that single out specific specimens for special protection. Any tree of 6 inches DBH or larger requires a Tree Removal Permit from the Planning Office, with retention encouraged through site-plan review and replacement required for trees within 10 feet of the building envelope. Replacement trees must have comparable shade potential and match the removed species where Michigan nurseries can supply. The Michigan DNR's Urban & Community Forestry program and the Michigan Botanical Foundation maintain informal records of the largest documented specimens of Michigan tree species, but there is no formal state Champion Tree statute. Farmington Hills' Tree City USA designation through the Arbor Day Foundation reflects ongoing commitment to urban-forestry standards including a tree-care ordinance (Chapter 34-5.18), a tree board or department (Planning & Community Development working with DPS), per-capita urban-forestry expenditure, and an annual Arbor Day observance. Trees of historical significance — those associated with platting events, historic homes, or notable community moments — receive informal recognition through the Historic District Commission's review of properties within designated historic districts under the Michigan Local Historic Districts Act (MCL 399.201 et seq.). Trees in regulated wetlands or floodplains are additionally protected under the Michigan Wetlands Protection Act (MCL 324.30101 et seq.) administered by EGLE. The Rouge River corridor, where many of the City's oldest and largest specimen trees are concentrated, receives additional protection through floodplain regulation and the Alliance of Rouge Communities watershed plan.
