Oak Bluffs selectmen agreed this week to sign an intermunicipal agreement that will allow the county to buy a building to house the Center for Living, but they balked at a second agreement that would establish oversight of the nonprofit organization’s programs for elderly Islanders.

The agreements have already been approved by the other five Island towns, according to county manager Martina Thornton, who attended Tuesday’s meeting. The agreements authorize the county to purchase the former Vineyard Nursing Association headquarters off State Road in Vineyard Haven. The Center for Living provides services to older residents, including a day program for those with Alzheimer’s disease and dementia.

Selectman Gail Barmakian questioned whether spending controls and oversight authority outlined in the inter-municipal agreements are adequate. She and other selectmen expressed confusion over how the Center for Living board of directors would work with a committee of town representatives and the county, which will own and maintain the building.

She noted the Center for Living just received a $1 million gift, bequeathed by a benefactor.

“There’s something too general here for me,” Ms. Barmakian said. “Do they administer the grant? Going forward if they get their own grant, who has control? I think it would be a nice gesture to contribute a couple hundred thousand to purchase the building.”

Finance committee member Maura McGroarty also raised concerns.

“I don’t know how it can be looked at and voted on without your finance committee at least reviewing it, she said of part two of the inter-municipal agreement. You have a nonprofit that can raise money and just did. Where does that money fit into the budget?”

Ms. Barmakian agreed to compile a list of suggestions to amend the second inter-municipal agreement. “It needs to be tightened up,” she said.

Selectmen agreed to review the document with the finance committee at a joint meeting on July 14.

In other business, CLE engineering of Marion presented a $5.6 million plan to repair and rebuild the crumbling sea wall along North Bluff.

“This is the culmination of seven years of intense planning,” said conservation commission chairman Joan Hughes. “We finally have a good plan and we have the money to do it.”

The plan calls for sheet piling, supported by a boulder revetment and capped with a 12 foot wide boardwalk extending from the new fishing pier to the town parking lot abutting the Oak Bluffs harbor.

The work is scheduled to be completed by June 30, 2016. Funding for the project comes from the Massachusetts Department of Conservation and Recreation and the state Seaport Advisory Council.

Selectmen accepted donations of $1,867 raised by the parks department to offset refurbishment of basketball and tennis courts at Niantic Park. Parks chairman Amy Billings said the cost of the project will exceed the Community Preservation Act funds allotted, so the department has begun a private fund-raising campaign.

Residents near the park told selectmen they are continuing a separate fund raising campaign to build a playground. Representatives of the group said they have raised about $66,000, and need to raise about $15,000 more. They expect to build the playground using volunteers. Construction is scheduled to begin in the fall.

In his report, town administrator Bob Whritenour said the little bridge dredging project is complete, with the sand distributed on town beaches. The board offered high praise for contractors and town officials who worked on the project.

But some residents who live near the beaches criticized the town over issues of access to the beaches.

“Over decades, the town has steadily pared away the infrastructure on the beach completely through neglect and demolition,” said Stanley Arend 3rd, reading from remarks prepared for the meeting. “Several years ago without any public notice that I know of, the town replaced the wooden stairs near the old main entrance with a rough cut, too steep sandbank entrance at Narragansett avenue that quickly deteriorated.”

Ms. Billings said a new stairway is planned, but permitting and design issues have held up the project, and she did not anticipate construction of new stairs in the near future.
