Signal Mountain planning commission moves to finalize subdivision regulations, weighs new site-plan rules

The Signal Mountain Planning Commission on Thursday moved to finalize a long-running update to the town's subdivision regulations and opened discussion on creating formal site-plan requirements for commercial and multi-family development.

Commissioners said the proposed revisions would remove cross-references that currently require developers and the town to rely on Hamilton County's subdivision rules and instead place the town's own definitions and standards directly in Signal Mountain's code. Garrett, a staff member working with the commission, says the existing draft points to Hamilton County's documents for preliminary and final plats, citing section 5-103.302 as an example.

The change matters because, commissioners said, relying on county regulations leaves Signal Mountain with limited direct control over subdivision specifications such as grading, street construction, lot sizes and right-of-way widths. Garrett told the commission the highlighted language in the draft reads that "specifications and requirements for preliminary plats shall be the same as those adopted by Hamilton County," and he urged the commission to adopt town-specific language so the town has clear, local standards.

Commissioners outlined the next steps: Garrett will prepare a clean draft of the revised subdivision regulations and a redlined version that shows the edits for the commission to review. Commissioners repeatedly said they want a final draft circulated to members in advance and to schedule an additional meeting or meetings to review the materials before any public hearing or vote.

In the same discussion, commissioners debated whether to adopt site-plan requirements (standards for commercial, multi-family, industrial and public or semi-public developments) before or after a zoning housekeeping update. Several members said site-plan requirements are a substantial gap in local regulation and give the town a tool to require screening, parking design, building separation and other design elements when a development comes forward. Others warned that site-plan rules and zoning changes would need to be coordinated and likely require multiple rounds of drafting and review.

Garrett said the commission already has roughly a year of work on residential plats and checklists that can be adapted for commercial site-plan requirements. He recommended completing the subdivision-plat language as a priority and then moving into broader zoning cleanup. Commissioners agreed to aim for a fuller review over the next meetings, with a target of discussing the item again and aiming for a vote at a later meeting (commissioners said a June meeting was a reasonable target).

Procedural items: the commission approved minutes from prior meetings after a motion and second (mover not specified; second by John Garbage). One member abstained from that vote because they said they were not on the Planning Commission at the time of the minutes under consideration. The commission also voted to table election of officers until a future meeting because several members were absent and one seat is vacant. The meeting ended with a motion to adjourn that carried.

Commissioners said they will ensure the draft materials'the clean and redline versions'and any supporting minutes or notes are circulated to all commission members ahead of the next meeting so new members have time to review the history of the revisions.
