A ban on allowing service stations in rural areas is one of several ordinance changes being looked at by the Buxton Planning Board.

“We shouldn’t have gas stations in rural zones,” planning board chairman Jeremiah Ross said in a workshop discussion Monday.

Buxton voters would have to approve any ordinance change in a town meeting. Selectman would determine whether to place ordinance changes proposed by the planning board on a town warrant for town voters to decide. But the town attorney would first review those proposed changes. A public hearing would also be required before going to voters.

There are no gas stations located in rural Buxton areas now, but Ross feared the future possibility of fuel leaking into an aquifer. “Do we want to prohibit gas stations from rural zones?” Ross asked.

Planning board member Harry Kavouksorian said gas stations could be permitted with a conditional use in rural areas under current ordinances. But a station would be limited to storing 1,000 gallons of fuel in the rural zone.

Several other changes are also being eyed by planners. James Logan, secretary of the planning board, recommended developing definitions of wetlands and vernal pools, which are seasonal pools of water.

Logan said not all wetlands are equal. He also wants a description of the resource protection district.

Another planning board member, Caroline Segalla, is studying whether the town should notify more than just abutters of applications to be heard by the planning board. In addition to sending letters to abutters, planners talked about the feasibility of notifying property owners within 100 feet of a proposal.

On another topic, Keith Emery, vice chairman of the planning board, said he favored “gang” mailboxes in clustered subdivisions. Emery said it would be easier for snowplow drivers.

Ross said proposed ordinance changes could be sent to voters in June. But, Ross didn’t foresee any zone changes on the horizon in Buxton.
