A planned overhaul and expansion of the Martha’s Vineyard Airport terminal building has received unanimous approval from the Martha’s Vineyard Commission, which deliberated on the application for less than half an hour on May 8 and signed the written decision later in the same meeting.

The speedy action cleared the way for the airport commission to solicit contractor bids for the construction project, a key step toward securing a $15 million grant from the Federal Aviation Administration.

The approved plan involves renovating 5,000 square feet of the terminal and adding 15,000 square feet to its existing 16,800 square feet of space.

Airport director Geoff Freeman told the MVC that the project is not intended to increase capacity, but to provide purpose-built space for Transportation Security Administration searches and a better traffic flow for arriving and departing passengers.

Commission chair Peter Wharton, who also sits on the airport commission, recused himself from the public hearing.

In other business, the Martha’s Vineyard Commission opened a hearing on an application from Island Gymnastics to add workforce housing at the West Tisbury campus where Island children train and perform gymnastics year-round.

Island Gymnastics owner Elizabeth Goodell, who lives on the property in a one-bedroom house with a three-bedroom septic permit, is seeking to build an accessory dwelling to accommodate one year-round tenant and two summer coaches who would stay for no more than eight weeks.

The coaches would stay in what Ms. Goodell described as three-season “sleeping porches” during their summer visits.

She agreed to add water metering to the proposed structure to confirm that Island Gymnastics is not producing more nitrogen than allowed.

A brief public comment period during the May 8 hearing produced only praise for Ms. Goodell’s plan.

“I support it hugely. I think the more we do these small [workforce housing] projects, the less we need the larger projects,” said West Tisbury resident Hilary Moore.

The commission closed the public hearing and kept the written record open until May 22, with deliberations to follow at a subsequent meeting.

In other business, commissioners agreed to take up the proposed demolition of a house on Main street in Vineyard Haven that has been condemned after a fire.

The house must come down for safety reasons, but the commission now will have the authority to rule on any plans to replace it with another building.

The Martha’s Vineyard Commission has concluded its public hearing on a controversial development at 97 Spring street in Vineyard Haven, hearing final testimony May 15 from property owner Xerxes Aghassipour.

Mr. Aghassipour said the opposition to his nine-bedroom project was misguided, noting that a multi-unit residence he developed in the same neighborhood has been occupied for the past year with no complaints from abutters.

A continued public hearing on the proposed new Martha’s Vineyard Boys and Girls Club in Edgartown, which made its MVC debut in March, resumes this Thursday.

Key planning concerns for the project include wastewater and landscaping to screen the new building from residential neighbors.

Also Thursday, commissioners will resume their public hearings on the proposed Cat Hollow affordable housing project in Vineyard Haven and on Millers Professionals’ application for new buildings at the Martha’s Vineyard Airport Business Park.
