A plan for Edgartown to purchase a run-down house on Main street will head to the town meeting warrant after selectmen signed off on the proposal this week, over continued objections from the property owner.

Selectmen voted unanimously at their meeting Monday to endorse a proposal for the town to spend $1.5 million in Community Preservation Act funding to acquire the house at 66 Main street through purchase or eminent domain. The property is owned by the Hall family and has been a long source of legal conflict in Edgartown.

The town proposes leasing the building, now vacant, as a retail establishment and creating a small park. The town also wants to spend another $1.5 million to buy a private parking lot next door that would be used for town parking.

The Community Preservation Committee voted unanimously in favor of the proposal last week, saying it was time for the town to take action.

Selectmen also appointed a committee charged with exploring options for the property and presenting the proposal at the town meeting April 11. The committee includes former Martha’s Vineyard Preservation Trust executive director Chris Scott, local developer Gerry Conover, town counsel Ron Rappaport, selectman Michael Donaroma and town administrator Pamela Dolby.

“I assume the committee is going to work with the owner to try to effect a friendly taking,” said selectman Arthur Smadbeck.

Prospects for an agreement with the owners appeared slim after Benjamin Hall Jr., representing his family trust, renewed his objections about the proposal. He has forcefully objected to the process the selectmen used to advance the measure to town meeting, and believes the town is underestimating the property value and cost of repairs.

In other business Monday, selectmen informally endorsed a plan to demolish four large boat sheds at the Mill Hill boat storage facility on Herring Creek Road. The facility was recently purchased by Prime Marina.

Attorney Sean Murphy, representing the marina, said the sheds would be replaced with modern shingled barn style buildings which will include fire suppression systems.

The project has been referred to the Martha’s Vineyard Commission.

The board also appointed Sam Sherman to the planning board to fill a vacancy; member Robert Sparks has left the board. Mr. Sherman has previously served on the planning board, and he will fill the remaining months of the two-year term. The seat will then be up for grabs in the town election in April.
