Residents press commission to protect single-family character as staff outlines overlay district history and legal fragility

Several residents urged the Royal Oak Planning Commission to preserve single‑family neighborhood character as staff and the city attorney briefed the commission on the purpose and limits of the city’s single‑family residential overlay district.

During public comment, Tricia Oliver, Scott Hammond and Jean Cernacki said the current master plan language and proposed form‑based zoning leave the door open to higher‑density infill and that some neighborhoods — including the Sherman Triangle and parts of Cambridge — have parking and access constraints that make multiunit redevelopment inappropriate. “Please protect residents’ interest in your build out of the zoning ordinance,” Oliver said, citing a recent approval at 111 N. Alexander as a precedent residents worry will encourage similar projects.

Staff presentations by Joseph Murphy and City Attorney Josh Markham reviewed the overlay’s origins after the 1999 master plan: the city rezoned 634 properties (roughly 100 acres) to 1‑family residential while recognizing existing 2‑family and multifamily structures through special‑land‑use status. Markham said the overlay succeeded at preventing large assemblages of properties but now presents legal and administrative fragility because its review standards (for example, whether a modification is “equal or less intense” or would “reduce property values”) are vague and highly discretionary. Murphy presented data he said show assessed values in overlay areas have risen (single‑family +144%; two‑family/multifamily +151%) and argued that the upcoming zoning rewrite with consultant Zoneco is an opportunity to add objective standards, targeted subdistricting, and outreach to affected property owners.

Commissioners discussed whether the higher assessed values are causal or reflect downtown proximity and walkability; they asked staff to ensure the Zoneco process includes outreach to owners listed in the overlay inventory. The presentation concluded without action; staff recommended further work in the zoning rewrite to modernize the overlay language, clarify evidentiary burdens, and reduce litigation risk.
