Dukes County commissioners interviewed the final three candidates for three seats on the Martha’s Vineyard Airport Commission at their meeting Wednesday.

A week ago, the commissioners interviewed the first three candidates — Richard (Peter) Wharton,

Richard Conrad and Geoffrey Wheeler.

On Wednesday each candidate­—John Ensor, Fred Fournier and Robert Zeltzer—was asked the same three questions as the candidates were asked the previous week.

• What they envision for the future of the airport and the business park?

• What role do they see the airport playing in response to global warming and other environmental challenges?

• How will they contribute to ensuring the ongoing financial security of the airport.

Interviews began with John Ensor, a retired government services executive from Edgartown who moved to the Island from Millersville, Md. three and a half years ago. Mr. Ensor said he would like to market the airport and business park as “business-friendly,” and be an advocate for helping businesses move through the “hurdles and red tape.”

“A good place to start is the marketplace here,” he said. “It’s got a lot of charm already and available space to broaden it and make it even better. I’m a believer that this is an ideal location.”

Fred Fournier is the owner of Landscope Landscape Construction and is the former Edgartown tree warden. He is also the current president and a founding member of the Martha’s Vineyard Business Park Tenants Association. Landscope’s headquarters is situated in the airport business park but Mr. Fournier told the county commissioners that his appointment to the airport commission would not be a conflict of interest.

“As soon as I thought about applying for this position, I immediately called the state ethics commission and explained my situation to them,” he said. “Because I’m a leaseholder, and my lease holding supersedes if I were to be appointed, it does not reflect my ability to serve on the commission.”

Mr. Fournier said he wanted to focus on being good stewards of the environment. “Recycling, water usage and disposal, maybe some soft scape helping to reduce the carbon footprint, adding some greenery, helping with the photosynthetic process, creating some more clean air for us would be helpful,” he said.

Mr. Fournier also said there could be more solar infrastructure at the airport, similar to the car charging stations at up and down Island Cronig’s, which could generate revenue.

Robert Zeltzer is a Navy veteran and retired businessman from Chilmark. He said his vision for the airport and business park is to preserve the elements that give the airport its character while adapting to necessary changes over time. Mr. Zeltzer said the future of the airport is a matter of having a vision and carrying it out in the most open and inclusive way.

“The airport is a critical economic element to the Island,” he said. “I’ve heard people say, ‘the airport is for the rich folks.’ And to some degree, it probably is, with private jets flying in and out as well as airlines that fly in from Washington and New York. But the people they bring in here spend money, they buy land, hire contractors and landscapers. Basically, I think we need to maintain the character of what the airport is but provide improvements to make it a little more user-friendly in some areas.”

County commissioners thanked every applicant for their interest in the position and willingness to volunteer. They expect to make their decisions on March 4.
