Falmouth conservation staff told the commission that recent mapping and proposed state rule changes warrant rethinking how the town treats enclosed space in coastal V‑zones.

Staff said they contacted Shannon Holtz, deputy director and floodplain specialist at the Cape Cod Cooperative Extension, who compiled peer town practice and confirmed that Falmouth is more restrictive than many towns when it comes to enclosures in V‑zones. Staff warned that state amendments to the Wetlands Protection Act regulations under discussion could require open pilings and limit enclosed floor area at a state level.

Commissioners debated whether to adopt a square‑foot ceiling (the group discussed the same 200‑sq‑ft benchmark used elsewhere) or a percentage of footprint, with practical concerns about elevators, stairways and storage. One engineer estimated a stairway, landing and a modest elevator could consume roughly 70 square feet, making a 200‑sq‑ft ceiling workable for basic access but limiting storage. Commissioners asked staff to invite Shannon Holtz to present LIMWA maps and to consult with the building department for implementation detail.

Next steps: staff will arrange a joint presentation with the county floodplain manager and follow up with the building department to align local rules with state codes and the LIMWA mapping before proposing final regulatory language.
