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.
