The Brookhaven Town Board has approved an $11 million bond resolution to finance the construction of new headquarters for the Mastic Beach Ambulance Company.

Building cost two years ago were estimated at $6 million but grew to $8 million because of economic factors such as inflation and increasing supply fees, town officials said.

Town officials said the project likely will total $9.5 million for construction and purchase of land.

“This starts the revitalization of downtown,” Mastic Beach Mayor Maura Spery said at Thursday night’s town board meeting.

Ambulance companies are special districts governed by Brookhaven Town.

“Good luck, we’re on our way,” Brookhaven Supervisor Edward P. Romaine said when the board unanimously authorized the expenditure.

Roughly 50 ambulance company members and several Mastic Beach officials attended the meeting.

Ambulance company officials say they have outgrown their facility on Whittier Drive, and years ago targeted a vacant grocery store on Neighborhood Road as a more suitable location for a permanent home.

Last month, Brookhaven Town and Mastic Beach officials demolished that empty building to make way for the new construction.

“It’s a perfect location and sorely needed,” said Brookhaven Town Councilman Dan Panico, who represents the Mastic Beach area. “I want the building to serve the ambulance company and residents.”

Bids for the project will go out soon, officials said. Construction is expected to last a year.

The average village homeowner would pay about $115 in additional taxes, town officials said Thursday.

Mastic Beach Ambulance Company responded to roughly 2,500 emergency calls in 2015.

Ambulance company officials said relocating would improve emergency response time by as much as three minutes.
