West Tisbury wants to make Lambert’s Cove Beach more accessible for elderly residents and people with disabilities.

That’s the idea behind a subcommittee formed Tuesday night at the West Tisbury conservation commission, where selectmen and members from the town’s parks and recreations department were present.

The new committee is charged with determining an effective way to make a dune at the entrance to the beach less of an obstacle for people to get around and over. The issue was brought to the conservation commission after about 30 residents this summer signed a petition asking the board to create a safer route.

Years ago, a small excavator was used to cut down the dune and make it less steep. The dune builds up naturally. But now other, more environmentally conscious options are being considered.

Conservation commission chairman Peter Rodegast said he and his board have begun exploring options for how to improve beach access for walkers who may be frail or have physical challenges. Building a boardwalk or a handrail are two possibilities, but Mr. Rodegast said he was open to more suggestions.

Administrator Maria McFarland spoke about what some towns on the Cape have done, including at Nauset beach in Orleans where a ramp and a boardwalk were built over a high dune.

The new committee has six members: Cheryl Lowe and Hap Bernard, who are co-chairmen of the parks and recreation department, Mr. Rodegast, Nate Morgan and Mike Turnell from the conservation commission, and selectman Richard Knabel.

The group will hold its first meeting in December. Mr. Rodegast said the timeline is to develop a proposal by February, in time to place an article on the annual town meeting warrant. “If the boardwalk is a solution it could be in place for next summer,” he said.
