About two dozen South Shore community leaders and residents voiced their opposition to the Serota Properties Islip Pines Project, a 136-acre, mixed-use development proposed for Holbrook.
The opponents, part of the 25 civic groups and chambers of commerce that form the South Shore Civic Alliance, said at a meeting Monday at the Sayville Public Library that they would ask the Islip Town Board to dismiss the project application.
The Islip planning board has tentatively scheduled a vote on the project's change of zone application for its meeting next Thursday. If the planning board approves it, the next step is for the town board to hold a change of zone vote.
The Islip Pines project has 350 housing units and nearly 600,000 square feet of commercial space on Sunrise Highway. The Suffolk County Planning Commission has approved a change of zone for the project, which also includes 339,000 square feet of retail, 818,000 square feet of industrial space, a great lawn and six ballfields.
Serota's lawyer Bram Weber said the developer is open to dialogue with opponents.
"When the project is opposed by an organization that is stridently opposed to many pro-growth, pro-development projects, we don't think engaging with that kind of organization is productive," he said.
Dan Gulizio, a former Islip town planner, said that dense projects could imperil the region's water quality.
Donna Pericone, president of the Bay Shore-Brightwaters Chamber of Commerce, questioned the direction of local planning.
"Who is doing the long-term planning?" she said at the meeting. "We don't need any of this."
