The Harbor View Hotel will close from Oct. 1 until Memorial Day 2019 as extensive renovations begin on the historic Edgartown hotel.

Edgartown selectmen approved the closure at their meeting Monday after hearing from hotel attorney Sean Murphy.

“It’s a long close, but this benefits the town,” said selectmen Michael Donaroma. “We’ll suffer through.”

The hotel came under new ownership in January of this year when Bernard Chiu, a seasonal Edgartown resident, bought it for $30 million. Mr. Chiu operates his investments out of Upland Capital Corporation, a Boston-based asset management and real estate investment firm.

The renovation plan calls for the addition of 26 new rooms and a spa in the main building, along with the construction of several new cottages on the hotel’s grounds.

In other business Monday, selectmen also approved sidewalk closures for construction projects at 12 North Water street on Sept. 17, and a 45-day closure along Church street by the Old Whaling Church per requests from the Vineyard Trust. The trust plans to restore the entire Church street facade of the Old Whaling Church.

“It needs it,” Mr. Donaroma said.

The vote to approve did not set a date for the sidewalk closure.

In other business, selectmen agreed to extend the deadline for lease negotiations on the Yellow House until Sept. 24. Christopher Celeste and Julia Celeste Tarka submitted the property’s lone lease proposal in July, with the hope of entering into a 30-year agreement with the town. According to documents submitted in the July proposal, they also plan to invest about $2.5 million into renovating the house and expanding a small, detached structure on South Summer into retail space.

With regard to the proposed Chappaquiddick cell tower, Chappaquiddick resident Robert Strayton submitted a petition with over 100 signatures from Edgartown voters asking the town to consider constructing the tower on town land to rather than at its proposed Sampson avenue location. The petition will now automatically go on the warrant for the next special town meeting.

Selectmen also gave the final signoff allowing the town of Tisbury to use Edgartown equipment and crew to complete the long-awaited project dredge project in the Tashmoo channel. The Tashmoo channel was last dredged in 2014 and shoaling has led to consternation among boaters and fishermen.

“It’s nice to put the dredge to work. We’ll keep you busy,” Mr. Donaroma told Tisbury harbor master, John Crocker, who attended the meeting.

The selectmen also approved a proposal to dredge three small areas in Lighthouse Pond after hearing from conservation agent Jane Varkonda.

“Lighthouse Pond has seen a great reduction in the amount of open water since hurricane Sandy, and we’ve had storm after storm and the pond is filling in at a rapid rate,” she said.

According Ms. Varkonda, the dredge committee has backed the proposal even though it still needs approval from the commonwealth, which could take up to a year.

“It’s moving. At least it’s moving,” Mr. Donaroma said.
