Yarmouth conservation panel issues negative determination for seaside addition

The Yarmouth Conservation Commission unanimously issued a negative determination of applicability on Feb. 6 for a proposed addition at 1 Seaside Village Road.

Attorney and agent Stephanie Sequin of Roderick & Wilcox told the commission the lot is roughly a half‑acre within land subject to coastal storm flowage, with a base flood elevation of 11 feet and an existing first‑floor elevation of 11.2 feet. The owners propose a 20.5‑by‑16‑foot, single‑story rear addition built on post‑supported sonotube footings rather than a new foundation, she said. Construction traffic would remain on the existing circular driveway; no trees or significant vegetation would be removed.

The commission asked about staging, protection of the existing septic and stormwater measures. Sequin said construction vehicles would remain in the front yard and equipment to set sonotubes would be limited to a mini‑excavator or small tracked machine. Disturbed ground would be reseeded with a native grass mix and stone placed along the roof drip line to manage runoff.

Commissioners moved for a negative determination; the motion carried unanimously. The order records no conditions beyond the standard limitations discussed during the hearing.

Because the work is within land subject to coastal storm flowage and entirely on a raised, post‑supported structure, the commission concluded the addition as proposed does not require a full notice of intent under the commission’s current jurisdictional rules. The record notes the contractor will need to protect septic infrastructure during work and remove demolition debris to the on‑site dumpster as described in the application.

The commission closed the item and moved to the next agenda matter.
