Planning and Zoning committee reviews multiple rezonings and a statewide vested-rights update

Summary
The January 6 planning and zoning committee reviewed several rezoning requests (Dodds Avenue, East 12th, North Chattanooga, Chamberlain Avenue) and considered zoning text amendments to align the city code with recent state changes on vested property rights and measurement graphics.
During the evening session on Jan. 6 the city’s planning and zoning committee considered a slate of rezoning requests and two text amendments intended to clarify vested-rights triggers and measurement graphics in Chattanooga’s zoning ordinance.
Karen Renick of the Regional Planning Agency reviewed case 0176 (Dodds Avenue), a request to rezone heavy industrial (IH) land to CC (commercial corridor) for a grocery/restaurant; staff found the request compatible with the Rossville Boulevard plan and recommended approval, while a nearby property owner raised traffic and speeding concerns that staff referred to Public Works for operational follow-up.
On East 12th Street, a homeowner sought to rezone from RN2 to RN3 to add an additional unit to an existing duplex; staff recommended approval with conditions limiting the site to a maximum of three dwelling units and a building height capped at 2.5 stories (35 feet) to align with plan recommendations and to address alley access and sight-distance concerns raised by neighbors.
Other cases included a North Chattanooga request to move from RN15 to TRN1, where planning recommended approval with a single-unit-dwelling condition after neighbors worried about multi-unit impacts; and a Chamberlain Avenue case to rezone from RN15 to RN13 to allow two homes in a location presently limited to one.
The committee also reviewed two text amendments sourced from staff. One amendment implements recent state statutory changes to vested property rights by clarifying that "submission" of certain development-planning materials can trigger vesting in some circumstances and by defining "substantial compliance" with local development regulations (the staff packet referenced Public Chapter 686 from 2014 and more recent guidance tied to Public Chapter 465). Karen Renick said staff incorporated MTAS (Municipal Technical Advisory Service) guidance and recommended carefully defining triggers such as preliminary plats, final plats, special-exception permits and planned-unit developments to avoid unintended vesting from conceptual rezoning site plans.
A second set of text amendments adds graphics to standardize how dimensions and average-grade building heights are measured on irregular lots, intended to improve clarity for enforcement and applicants.
Council and staff agreed to circulate supporting materials and slides, and staff offered to provide contact information for applicants and opponents on specific cases so council members could follow up with constituents prior to full-council action.
