Planning commission splits on proposed zoning amendments; approves road dedication and raises A‑1 setbacks

COFFEE COUNTY, Tenn. — The Coffee County Planning Commission on April 22 debated three proposed amendments to the county zoning resolution — on water and fire protection, road dedications and traffic studies, and setbacks — and issued mixed votes that will move some measures to the full county commission.

The commission voted to decline a proposed water-and-fire-protection resolution, approved a roads-and-traffic resolution requiring a 25-foot dedication from the centerline and a traffic study for larger subdivisions, and separately approved a motion to set A‑1 setbacks at 50 feet front, 50 feet rear and 50 feet side for all A‑1 parcels. A separate, similar setback proposal that the presenters had submitted was declined by the commission.

The votes came after public testimony and technical testimony from local fire officials who urged tighter rules for rural development. “It says deficient water for fire protection should be grounds for rejection of proposed developments,” resident Ashley Gunn told the commission, citing state water rules. Dylan Harris, assistant chief at New Union Fire Department, told commissioners the countywide average response time for the closest unit to arrive at a structure fire was 14 minutes and 1 second and cautioned that modern homes can reach flashover in three to five minutes. “By the time we get there, most of these houses have already gone to fully combustion,” Harris said.

What the commission considered

A group representing residents affected by the county moratorium presented three separate resolutions and asked the planning commission to vote them up or down before sending them on to the full county commission. The resolutions as presented tied development lot size and lot width in A‑1 zones to the presence of an approved public water connection and a functioning hydrant within one mile by road distance. The presenters proposed a tiered system: where a functioning hydrant and water service exist within one mile, a major subdivision could have 0.8‑acre lots with a 100‑foot minimum lot width; if water exists but no qualifying hydrant within one mile, a 1‑acre minimum and wider lot widths would apply; if neither water nor fire flow exists the proposed minimum rose to 2 acres. The group asked the planning commission for an up-or-down vote on those draft provisions.

Commission response and actions

Commissioners and county staff noted that much of the suggested language on minimum fire flow and water‑system requirements already appears in the county’s zoning resolution and subdivision regulations. Commissioners declined the water/fire protection resolution, saying the content largely duplicated existing language in the zoning resolution and subdivision regulations; the presenters and some commissioners disagreed about whether the current text was sufficiently explicit.

On roads and traffic, the commission approved a resolution that would require developers fronting substandard roads to dedicate or grant a public‑use easement to yield 25 feet from the centerline on the developer’s side; it also set a requirement for a licensed traffic engineer to perform a traffic study for major subdivisions of 15 lots or more. Proponents described the 25‑foot from‑center dedication as a compromise short of a full 50‑foot right‑of‑way requirement.

Setbacks and fire safety

Discussion of setbacks drew the strongest testimony. Sammy Morton, identified at the meeting as chief of the county’s rural fire departments, and Dylan Harris described multiple incidents in which fire spread quickly between closely spaced houses and cited modern construction materials and lithium‑ion batteries as factors that shorten time to flashover. Morton said smoke detectors may not alert occupants when external fire spreads along vinyl siding and roofing materials before internal smoke reaches detectors.

After the debate commissioners moved and approved a separate motion to set A‑1 bulk requirements to 50 feet front, 50 feet rear and 50 feet side (the commission recorded the motion as approved and agreed to forward the amendment to the full county commission). A different resolution presented by the public advocates that sought to preserve or restate existing language was voted down by the planning commission.

What happens next

Commissioners said the approved amendments and proposals will be forwarded to the full county commission for consideration. County staff and the newly hired planning professional noted that a public hearing and 15‑day advertisement are required for zoning resolution amendments; that scheduling may delay some items before the full commission. The commission discussed timing for public notice and the next full commission meeting.

Community context

Speakers at the meeting framed the debate around infrastructure limits in rural areas, volunteer fire department capacity, and potential insurance impacts: one presenter cited Municipal Technical Advisory Service (MTAS) material noting that ISO ratings — which affect homeowner insurance costs — reflect water supply as well as fire department capability. Commissioners repeatedly emphasized that existing county bulk regulations and subdivision rules apply and that any amendment forwarded to the full commission would be subject to the public‑notice and hearing process.

Ending

The planning commission did not adopt a comprehensive new water‑or‑fire‑flow standard at this meeting, but it approved a roads/traffic requirement and a change to A‑1 setbacks; the full county commission will receive the approved items with public notice and hearing requirements to follow.
