Board OKs side‑setback variance for riverside house addition; staff flags floodplain and septic constraints

Trousdale County's Board of Zoning Appeals approved a side‑setback variance to allow a three‑bedroom addition on a riverside house after staff explained technical constraints related to flood zone designation, septic placement and fire‑code separation.

Michael Dodd, who identified himself as the contractor on the project, asked for a side‑setback variance so his clients can build an addition that will convert the house into a four‑bedroom, four‑bath dwelling. Rosalie Myhand told the board the property lies in flood zone AE and therefore will require a certificate of elevation showing finished floor elevation is 1 foot above base flood elevation; she explained those certificates are provided after construction. "They can provide us a certificate of elevation," staff said about the surveyor's ability to meet NFIP requirements.

Myhand also pointed out that the front of the house contains the septic field and the rear contains an in‑ground pool, so the proposed addition on the side is the only viable location. She cited fire code and noted the proposed 15‑foot separation from the side property line exceeds the 10‑foot minimum required between structures. The applicant and staff confirmed the planned HVAC will be electric, avoiding gas venting concerns for neighbors.

Mark Presley moved to approve the variance; Eric Langford seconded and the board approved the motion on a voice vote. Staff confirmed required public‑hearing signage had been posted in the newspaper as required by local ordinance and state law.

The variance allows the property owner to pursue building permits; the construction will still need to comply with floodplain elevation certification and all applicable permitting requirements.
