Signal Mountain Planners Review Red Maple Run: 15 Lots on James Boulevard and a Test of the New 5-Acre Rule

A 15-lot subdivision on James Boulevard has become a test of Signal Mountain's new, much stricter lot-size rules.

The Signal Mountain Planning Commission met Thursday, Nov. 5, to review the conceptual plan for Red Maple Run, according to the Chattanooga Times Free Press. The proposed subdivision covers about 22 acres at 1495 James Blvd.

Project engineer Zeca Ferraz told the board the 15 lots would average 0.92 acres. The same report lists 10.7 acres for conservation. Fifteen lots averaging 0.92 acres total about 13.8 acres; adding 10.7 would exceed the reported 22-acre site if the areas were separate. The report does not reconcile those figures or establish whether they overlap.

The catch: the town's new subdivision rules require lots of at least 5 acres. Board members asked whether those rules apply to this plan.

Why timing is the whole case

The answer may turn on the calendar.

The Times Free Press reported that the developer first submitted a conceptual plan in April 2026. Town staff found it incomplete. That filing came after the Town Council approved the new rules on first reading, but before the final vote in May 2026.

So the plan was filed in a gap. The new rules had cleared one vote but were not yet law.

The town passed those rules after a fight over a 106-home subdivision on Shackleford Ridge Road. Most of the Planning Commission voted to approve that project because it met the town's rules at the time. But several commissioners said the town's roads and services could not handle that many new residents.

What happened in September

Red Maple Run first came before the commission on Sept. 3. Town minutes show it did not get far.

Chairman Andrew Coyle raised a point of order. He said the first submission was not a real conceptual plan. The minutes cite a town subdivision rule that requires information to be presented at least 15 days before a Planning Commission meeting. A revised plan had come in on Aug. 24, ten days before the meeting.

Other commissioners agreed. Commissioner Clay Crumbliss noted that the Town Council had changed the zoning ordinance and said the plan did not comply. Commissioner Austin Scofield said the town still did not have a complete, compliant conceptual plan.

Coyle ruled the application was not in compliance. Then the board turned to the bigger question. Crumbliss asked the town attorney to determine whether the plan was vested. Coyle moved to have the town attorney review the application's claim of vesting rights. Scofield seconded, and the motion passed.

What "vested" means in Tennessee

Tennessee's vesting law, Tennessee Code § 13-4-310, is why the April filing date matters.

Under the statute, a vested property right is created when a preliminary development plan is submitted to the local government. Once vested, the development standards in effect on the submission date stay in place for that property during the vesting period. The law lists lot size among those standards.

The basic vesting period for a development plan is three years from submission, if the developer gets final approval, permits and starts site work in that window.

But there is a key limit. The statute says a plan does not vest unless it substantially complies with local rules. It also says a sketch that does not describe the use, density and utilities with reasonable certainty cannot count as a final development plan.

That is why the September debate focused on whether the original submission was complete. If the April plan counts, the old rules may govern. If it does not, the 5-acre minimum likely applies. The town attorney's review is meant to answer that question. Its answer will shape what can be built on the site.

Other rule changes in the works

The commission is also rewriting Article 4 of the town's subdivision regulations. The Sept. 3 minutes list several draft changes:

• Conservation subdivisions: Require them for all subdivisions of 10 or more acres.
• Stream buffers: Increase from 30 to 75. The minutes do not list units; they note that normal is up to 60.
• Access: All major subdivisions must have two access points.
• Wildlife corridors: Two commissioners recommended leaving this out. A suggestion was added to require developers to provide animal data.

The town attorney also told the board that a certificate of adequacy from schools cannot be required.

Residents weighed in too. Tree Board chair Jim Webster said the board is working on tree language for the ordinance. He also said known issues with a property, such as abandoned coal mines raised at Shackleford Ridge, should be disclosed rather than discovered.

Resident Miles Jorgeson urged the board to weigh the ecological impact of stream buffers, which he said protect the environment and help wildlife move. Grace Mynatt said the conceptual plan checklist needs work: it does not require a lot table, and conservation land was overlapping private lots. She asked that required conservation land be calculated and shown.

What it means for Signal Mountain owners

A 5-acre minimum changes the math on land. Large tracts may be harder to split, which could limit new homes on the mountain. For people who already own homes, less new supply can help hold demand. For landowners hoping to subdivide, the new rules may lower what a developer will pay.

What is Red Maple Run in Signal Mountain?

The Times Free Press describes a proposed subdivision at 1495 James Blvd. with about 22 acres, 15 lots averaging 0.92 acres, and 10.7 acres for conservation. Those reported areas do not add up if separate; overlap or a different acreage basis is not clarified in the report.

What is Signal Mountain’s new minimum lot size?

The Times Free Press reports the town’s new subdivision regulations require lots of at least 5 acres. They passed their second and final vote in May 2026.

Why might the old rules apply to Red Maple Run?

The developer first filed a conceptual plan in April 2026, before the final vote on the new rules. Under Tennessee’s vesting law, a plan that substantially complies with local rules can lock in the standards in effect when it was submitted.

How long does a vested development plan last in Tennessee?

Under Tennessee Code § 13-4-310, the basic vesting period for a development plan is three years from submission of the preliminary plan, if the developer gets final approval, permits and begins site preparation within that time.

What other subdivision changes is Signal Mountain considering?

Draft changes discussed Sept. 3 include requiring conservation subdivisions for tracts of 10 or more acres, raising the stream buffer from 30 to 75, and requiring two access points for all major subdivisions.
