Route 110 Drainage and Roadway Improvements

Alleviating Chronic Flooding
Halesite, Town of Huntington, Suffolk County, New York

The New York State Department of Transportation (NYSDOT) needed a solution for chronic flooding, pavement deterioration, and traffic congestion along a one-mile stretch of Route 110 in Halesite, New York. Under NYSDOT management and with joint venture partner L.K. McLean Associates, we designed drainage and roadway improvements that reduced the magnitude and frequency of flooding.

foot-wide transverse roadway grate inlets

This project incorporated several distinctive design features, including the use of 24-foot-wide transverse roadway grate inlets to redirect excessive stormwater away from the roadway's low point, via culverts, pipes, and streams, to a new filtration basin. This configuration was a unique structure classified as a bridge by NYSDOT, due to its size. The project also included an offline articulated-concrete/planted floatables filter system, to keep debris out of the creek and provide NYSDOT with an easy way to periodically remove the debris with its maintenance forces.
