Staten Island completes $84 million storm sewer upgrade in Sandy-hit New Dorp Beach
(UI) — The City of New York has finished a $84 million underground infrastructure project in Staten Island’s New Dorp Beach neighborhood, adding more than 1.6 miles of new storm sewers and 101 catch basins in an area devastated by Superstorm Sandy.
The multi-agency effort led by the NYC Department of Environmental Protection (DEP), Department of Design and Construction (DDC), and Department of Transportation (DOT) rebuilt drainage systems, raised or lowered street elevations for proper stormwater flow, and replaced water mains, curbs, and sidewalks. The project began in 2019 and was funded by DEP, DOT, and FEMA.
“This project will help ease [residents’] concerns about flooding,” said DEP Commissioner Rohit T. Aggarwala. “The completion of this new storm sewer system ensures that the community is better protected against future extreme weather events driven by climate change.”
In total, 8,701 feet of storm sewer was installed, along with 16,852 feet of new sanitary sewers and more than 17,555 feet of water mains. Elevation changes included raising Milton, Finley, and Cedar Grove avenues by over a foot and lowering Hett Avenue by 10 inches to accommodate gravity-fed drainage.
More than 880 homeowners had their driveways or front yards adjusted to align with the new street grades. Additional upgrades include ADA-compliant pedestrian ramps, curb replacements, and 7 acres of new sidewalk.
“This $84 million investment will bring some much-needed peace of mind to people in low-lying areas who never had proper storm sewers before,” said DDC Commissioner Thomas Foley.
The project was designed by STV Inc. and built by contractor JR Cruz of New Jersey.
