The Martha’s Vineyard Commission last Thursday unanimously approved a proposal to renovate and expand Morning Glory Farm in Edgartown, which was under review as a development of regional impact (DRI).

The plan was reviewed by the commission’s land use planning committee last Monday and approved by the full commission last Thursday after 30 minutes of deliberation.

The plan now goes before the Edgartown planning board for review at the local level.

Farm owners Jim and Deborah Ath-earn want to expand the farm stand and the commercial kitchen operation from 5,945 square feet to 8,342 square feet.

Under the plan, one 2,700 square-foot greenhouse will be relocated and taken out of retail use, and a new 800-square-foot greenhouse will be built adjacent to the farm stand. The plan calls for relocating the parking area and adding 13 new spots, and relocating the entrance to the stand.

Mr. Athearn is a former member of the commission; he resigned his post last month after 10 years representing the town of Edgartown. He did not attend the proceedings before the commission on the Morning Glory plan; other family members did.

The Athearn family submitted a long list of conditions that were accepted by the commission and will became part of the written decision to approve the plan.

The conditions include stipulations for height, building materials and landscaping. And the farm owners will agree to take steps to offset additional nitrogen loading into the Edgartown Great Pond by converting from synthetic to organic fertilizer in certain areas of the farm, and install bio-remediation swales or grass filter strips to mitigate nitrogen loading from a compost operation.

“As we proceed into the future we are going to be living more locally. And there is a definite advantage to having the ability to grow our own crops locally,” commissioner Peter Cabana said just before the vote.

Commissioner Linda Sibley agreed, calling the plan an environmental net gain. “Farming does contribute a good deal of nitrogen, which is an issue,” she said, adding: “But when weighing the benefits and detriments, it is important to remember the products they grow are essential . . . they offer more of a benefit than a subdivision . . . plus there is right way and a wrong way to go about [farming]. And they are proposing to do things the right way.”

Voting in favor were Mr. Cabana, Ms. Sibley, Douglas Sederholm, Ned Orleans, Kathy Newman, John Breckenridge, Carlene Gatting, Bill Bennett and chairman Christine Brown.
