The Dix Hills Fire Department is set to unveil its $550,000 training facility on Sunday.
A dedication and ribbon cutting is scheduled at 11 a.m. at the building, located at the department's station at 590 Deer Park Ave., just south of the Long Island Expressway.
"I'm very proud of this building," Fire Commissioner Larry Feld said. "It's been about 11 years in the making of saving money, and we're at the end."
Construction of the two-story, 27-foot-high, 2,170-square-foot prefabricated building began last summer.
The facility will give volunteers hands-on firefighting experience under safe conditions right in their own neighborhood, Feld said. The site is about 150 feet from the nearest house.
Feld said the district had been setting aside money for the facility in its Capital Reserve Land and Building Fund for about 10 years, so there will be no increase in fire district taxes.
"This will make a better department where we can teach our people and hone our skills on training and learn different techniques."
