After months of back and forth, Tisbury selectmen have signed a contract to allow a three-day music festival to take place in Veterans Memorial Park this August.

The festival is the first of its kind in the town, and has been dubbed Beach Road Weekend by organizers. John Fogerty and longtime Grateful Dead bassist Phil Lesh are the planned headliners. The question of whether alcohol will be sold at the event remains undecided.

Concert organizer Adam Epstein of Innovation Arts and Entertainment returned to selectmen at their meeting Tuesday to discuss some of the details including shuttling, security, electricity and crowd control.

“It’s been a very, very exhaustive effort,” Mr. Epstein said before selectmen took the final vote to sign the contract.

Mr. Epstein is known for producing the summertime Martha’s Vineyard Concert Series, which has hosted musicians and speakers from Mavis Staples to Davis Sedaris in recent years. Early this year, he approached Tisbury selectmen about the more ambitious three-day festival event.

Some town residents had raised concerns about drawing thousands of people to the downtown area in the middle of August. But on Tuesday enthusiasm prevailed, with selectmen unanimously backing the festival after a short discussion.

Selectman James Rogers asked Mr. Epstein if he had attempted to contact abutters to the town park.

Mr. Epstein said he had gone door to door earlier this month leaving his contact information and festival information at each house.

“We’ll continue to keep ourselves open like this so if there is anything that anyone would like to hear we’re of course open to it,” he said.

The contract agreement does not specify whether alcohol will be sold at the festival, but it does include stipulations in the event that selectmen decide allow alcohol sales. The cost to rent the park, for example, would increase by $15,000 if sales are allowed. Police chief Mark Saloio has said regulating alcohol consumption will be easier for law enforcement with sanctioned sales. Chairman Melinda Loberg appeared to agree.

“I think that was one of our rationales in the vote to allow restaurants to serve beer and wine rather than to have a BYO component to food service,” Mrs. Loberg said. Mr. Epstein said wristbands could be used to track how much adults over 21 were drinking. “We are fully prepared to restrict access,” he said.

He added: “The revenue generated is frankly important to the overall operation.”

Selectmen said they will discuss the alcohol component at a later date.

The contract outlines obligations on both sides, beginning with a pre-festival payment from the entertainment company to the town of $83,000 for the event. That includes estimated public safety costs, $25,000 for use of the park and a $25,000 damages deposit. The company has agreed to pay the town for all additional public services including police, fire, ambulance, and public works. The town retains the right to disapprove of festival activities and decibel levels.

The town has agreed to landscape the park in advance of the festival and remove a fence and bleachers. The town will also allow access to the town landfill, temporary access to electricity and access to wastewater facilities.

Chief Saloio said he and fire chief John Schilling and EMS coordinator Tracey Jones had been collaborating to prepare for the event.

“We’ve actually formulated a traffic safety plan for the immediate area of the concert vicinity,” he said.

The event is scheduled to begin Friday August 9 with a 7 p.m. screening of Jaws. On Saturday August 10, live music is planned from 1 to 9 p.m. and on Sunday August 11 from 1 to 8:30 p.m., with Phil Lesh closing out the festival.

Innovation Arts will rent the park from Tuesday August 6 to Sunday August 11.
