The opening of a new gas station, car wash and convenience store in the airport business park has been delayed for another month, owner Louis Paciello said this week.

Mr. Paciello told the airport commission at a meeting in July that the new Shell station would be open in August, with the car wash due to be open a little later.

But speaking briefly to the Gazette by phone Monday, Mr. Paciello said permitting problems and an ongoing lawsuit with the former tenant at the property have been factors in the delay.

Mr. Paciello said he had originally planned to open the station in July, but construction was halted by the Edgartown planning board after it learned that the convenience store was way over the 500-square-foot limit under town zoning bylaws.

The convenience store and gas station were reviewed and approved as a development of regional impact by the Martha’s Vineyard Commission last December.

The project included more than 2,200 square feet of space for the convenience store. In March of this year the planning board wrote a letter to Edgartown building inspector Leonard Jason Jr. advising him that the convenience store exceeded allowed footage under zoning and would need to be modified.

To avoid going back to the commission and planning board for approval of a new plan, Mr. Paciello said he will build out the station but keep the convenience store portion at 500 square feet. He said the rest of the space will be used for storage for the time being as he considers alternatives.

“I take full blame. I should have done more homework,” he said. “The only thing I can do right now is build a 500-square-foot store.”

Mr. Paciello owns two other gas stations in downtown Edgartown: the Depot Corner Shell station and a Mobil station.

His company has also been caught up in protracted litigation involving the former longtime owner of Airport Mobil and the airport commission. The commission voted 18 months ago to not renew the lease for Mobil station owner Michael Rotondo, deciding instead to award a bid for the lease to Mr. Paciello.

The case has seen numerous twists and turns but remains active in Dukes County Superior Court, where a status conference is set for August 28.

“We had a lot of stuff dismissed against us, but we’re still tied in,” said Mr. Paciello. “It’s just costing me a lot of money.”

Meanwhile, he said he is waiting for a final signoff from the Edgartown building inspector on the revised plan for the convenience store.

“The petroleum side is pretty much done. They just have to set the pumps and the wires and we’ll be pretty much ready to go,” he said. “We just got to get it up and running as soon we can.”
