The Chilmark conservation commission has approved two long-debated projects to restore Squibnocket Beach and build a new access road to the homes at Squibnocket Farm. Barring any appeals, the projects could begin as soon as mid-September.

At a meeting Wednesday afternoon, the commission made a few final tweaks, but after two years of public review — including by the Martha’s Vineyard Commission this year — most of the questions had been answered.

The town of Chilmark plans to remove an existing revetment that supports the current access road and town parking lot, and relocate the parking lot farther inland. And the Squibnocket Farm Homeowners Association plans to construct a new access road, including an 11-foot-high bridge over wetlands bordering Squibnocket Pond.

The project as a whole has been called a managed shoreline retreat, although not everyone agrees with the plans on both sides to use hard structures. Removing the parking lot and revetment will allow the beach to migrate inland over time, but will also set the clock for a second phase of retreat.

Much of the discussion on Wednesday focused on what to do with the remains of previous revetments that were outside the scope of the projects. In response to concerns raised at the commission’s meeting on May 18, Reid Silva of Vineyard Surveying presented a plan for removing some of the bluestone that had been placed in the area and rearranging native stones to help reduce the impact of waves around what is known as Money Hill.

Commissioner Chris Murphy has long argued that all the stones should be removed, in part to prevent scouring caused by the refracted waves. But Mr. Silva said that would leave that portion of the shoreline more vulnerable to erosion. “What we’ve designed here, in our eyes, is a compromise,” he said, noting that an order of conditions allows the revetments to be maintained in perpetuity. “It was never the intent to say man will not have any impact here. That will happen wherever man is.”

Other commissioners agreed the plan was at least a step in the right direction.

“We are replacing something very artificial with something less artificial,” said commissioner Pam Goff, also noting a spirit of compromise.

The town portion was approved with several conditions, including a landscaping plan consistent with the earlier MVC conditions, and fencing along the sides of the new road to protect the resources around a skiff launch. A future path from the parking lot to the beach must return to the commission for approval once the project gets to that stage.

Sue Regan, who attended the meeting, advocated for signs or other means to keep people off an artificial dune that would help buffer the area from storms. She acknowledged arguments that signs and fences don’t often work, but pointed out that the town has invested in signs elsewhere and that some sort of approach would be useful at Squibnocket. Mr. Murphy encouraged residents to bring those concerns to the town separately.

Discussion surrounding the association portion of the plan was sparse in comparison. The commission approved the plan with several conditions, including a requirement that the developers report back on the rate of erosion at the site.

They also agreed to require the removal of all of the remaining revetment stones, at the expense of the homeowners association, but not until the second phase of retreat, starting when the shoreline is within 30 feet of either end of the bridge.

The commission did not require duplication of 25 square feet of wetlands that the project would displace through the piles on the bridge. And maintenance related to the piles, railings, and above-ground utilities will not require prior notice to the commission. But maintenance of the causeway itself will require commission approval.

Both projects were approved unanimously. The final vote after about an hour of discussion was followed by applause and congratulations, but also a note of caution, given the 20-day appeal period and the ferocity of debate over the last two years.

“There is no bubbly being uncorked yet,” selectman Bill Rossi said.
