The Town of Brookhaven, New York, has completed a $482,000 culvert replacement and stormwater mitigation project along Poospatuck Lane in Mastic, designed to reduce flooding, limit saltwater intrusion and improve local water quality.

The project, led by the Brookhaven Highway Department and Councilwoman Karen Dunne Kesnig, included replacing a failing culvert and constructing a bio-retention area at Second Neck Creek to naturally filter and absorb stormwater runoff before it enters the waterway.

“This area of Mastic has been repeatedly impacted by saltwater intrusion during high tides,” said Highway Superintendent Daniel P. Losquadro in a press release. “Following the stormwater control improvements completed by the Highway Department, Poospatuck Lane will be much safer and more eco-friendly.”

Councilwoman Dunne Kesnig added that the effort “greatly benefits the Mastic community by reducing flooding and improving water quality.”

The initiative is part of Brookhaven’s broader effort to address water quality and resilience challenges through large-scale stormwater mitigation and infrastructure improvement projects led by the town’s Division of Stormwater Management.
