Lying on the shore of Norton Basin, an inlet of Jamaica Bay, the Bayswater neighborhood of Queens suffers from frequent tidal flooding and pavement erosion. To improve drainage in the area, mitigate flooding, guard against sea level rise, and restore streets to a state of good repair, the New York City Department of Design and Construction (NYCDDC) is undertaking a major upgrade of roadways and infrastructure in the area.

EnTech is leading the design, totaling 5,000 lf of roadway, encompassing full and partial reconstruction segments. The scope of work includes adding a 2,170-foot-long steel sheet pile seawall, raising roadway profiles, widening portions of streets, adding sidewalks, and realigning intersections to improve traffic flow and pedestrian safety. A new drainage system will be installed, as well as the replacement of 7,600 lf of water main and 4,300 lf of sanitary sewers.

EnTech’s civil design team is developing pavement, streets, schematic geometry, sewers, water main, stormwater management, and maintenance and protection of traffic (MPT) designs. The firm’s designs incorporate flood resiliency, mitigation measures, and green infrastructure goals. The firm’s geotechnical team conducted subsurface exploration and is leading the design of the seawall. Transportation engineering services have included traffic studies and designs for the reconstructed intersection. EnTech is further overseeing surveying, sanitary force main design, and tree planting services.
