Tisbury police detective William Brigham has been named second in command to interim police chief Christopher Habekost, following a unanimous vote by the select board Tuesday afternoon.

Detective Brigham will be promoted to lieutenant for an appointment of up to six months, matching Chief Habekost’s own short-term appointment.

The interim chief told the select board that Detective Brigham, who joined the Tisbury force in 2019, was his choice for the role and has the support of police department members.

“He’s been doing a very good job and he also has a wealth of knowledge from working previously with two other police departments in Massachusetts,” said Chief Habekost, who was appointed last week to follow retiring chief Mark Saloio.

The position of lieutenant currently is not listed on the police department’s approved staffing plan, requiring union negotiations before proceeding with the appointment, town administrator John (Jay) Grande told the board during Tuesday’s regular meeting on Zoom.

“We’ll need to enter into impact bargaining with the police union,” Mr. Grande said. Impact bargaining takes place when management makes changes to established working conditions.

Mr. Grande said he already has met with the interim chief and union representatives to discuss the staffing issue.

“They’re in support that this position is key in moving forward, so the union supports it,” he said.

“This is not envisioned necessarily as a permanent position,” Mr. Grande added. “The actual appointment is to a temporary lieutenant position, subject to impact bargaining.”

The board voted unanimously to approve the appointment, effective for six months, and for Mr. Grande to begin the required negotiations with the police union.

In other business Tuesday, the board granted conditional approval of an agreement with music presenter Adam Epstein to hold a concert series in Veterans Memorial Park later this month.

The agreement still needs a green light from town counsel and an updated dollar amount for Mr. Epstein’s deposit, Mr. Grande said.

“I will be . . . finalizing payroll for any town services provided by personnel,” he said.

Tisbury planning board member Ben Robinson challenged the town to add a fee for long-term maintenance of the park.

“If we continue to have concerts every year, in five or 10 years the town will be looking at extensive rebuilding of the fields,” Mr. Robinson said. The concert series should pay part of the cost, he argued.

But board chairman Jeffrey Kristal pushed back.

“It doesn’t really destroy the field like, Ben, you are saying,” Mr. Kristal said, citing more frequent uses of the park including soccer and softball.

“I know that Mr. Epstein puts a considerable amount of money back into it, and the department of public works has a line item in its budget for the field,” Mr. Kristal added.

Mr. Epstein said his company hired a landscaper to aid in remediating the park after the three-day Beach Road Weekend festival in 2019, and will again this year.

“I’m proud of what we did to restore that field,” he said, adding that he pays significantly more to use the park than the sports teams Mr. Kristal mentioned.

“I think everybody who uses the park should be treated equally,” Mr. Epstein said. “Everybody should be asked to pay a surcharge for long-term use of the field if that’s going to be the case.”

Mr. Epstein also said with all-reserved seating, tickets sold in blocks of four and capacity limited to 2,000 people per show, field wear will be limited this year.

“There’s not going to be as much general movement and walking around the site,” he said.

“Everyone gets their own beach mat . . . or they can buy a beach chair from us.”

Mr. Robinson’s suggestion went no further, but Mr. Grande said it would be something to consider when negotiating future agreements for the park.

“This is a new idea that you are putting forward, and I think it is an important one,” Mr. Grande said. “Your point is very well taken . . . I appreciate the comment.”

The weekend of concerts in the park runs from July 23 to July 25.

Also Tuesday, the board quickly approved license renewals for the Scottish Bakehouse, the Larder, Island Fresh Pizza and Subs and Bluefish Taxi, and two one-day alcohol licenses for events at the Martha’s Vineyard Museum on July 16 and July 23.

A new restaurant, Fish Tales MV on Main Street, also received an eatery license. An affiliate of next-door restaurant Waterside, the new spot will have its own kitchen and operate independently, owner Stephen Bowen told the board.

“We’re looking forward to getting things going and catching the main part of the season,” he said.

The board concluded the meeting by declaring a German shepherd named Ranger a dangerous dog, following more than an hour of testimony from town animal control officer Kate Hoffman, dog owner Andrea Peraino and two Island visitors who were bitten by the animal outside the Black Dog Tavern over a three-day period in late May.

Stopping short of ordering Ranger to be euthanized, the board approved a series of measures recommended by Ms. Hoffman to keep the dog away from the public.

The conditions include constructing six-foot-high double-gated entries at all exits and entrances of the property where the dog is kept, humanely muzzling it with a basket muzzle when it leaves the property and seeking at least $100,000 insurance for damage done by the dog, among other stipulations.

Ms. Peraino has two weeks to comply, with Ms. Hoffman entitled to inspect the work.

If Ranger bites again, anywhere in Massachusetts, Ms. Hoffman has the right to seize the animal.
