(Staten Island, NY – December 11, 2020) The New York City Departments of Environmental Protection (DEP) and Design and Construction (DDC) today announced that work has been completed on an upgrade of storm sewers in the Staten Island neighborhood of Bay Terrace. The $10 million project has helped eliminate severe street flooding that would often occur at the Amboy Road overpass, just north of South Railroad Avenue during rainstorms. Work also included the replacement of water mains to improve water service reliability in the area, as well as the replacement of sanitary sewers to help safely take wastewater to treatment plants. DEP provided the funding for the project while DDC managed the construction, which began in January 2019.

“This $10 million investment has improved drainage and helped to reduce street flooding at a problematic Staten Island intersection, as well as upgraded the neighborhood’s water delivery infrastructure and sewer system,” said DEP Commissioner Vincent Sapienza. “I want to thank our colleagues at DDC for once again shepherding another project to a successful completion.”

“This project helps relieve problems at a known flooding location while upgrading local infrastructure and beautifying the area with new plantings,” said DDC Commissioner Lorraine Grillo. “We partner with DEP all over the City to improve stormwater drainage and to increase the reliability of the water supply system, with 15 active projects on Staten Island right now representing more than $650 million in overall investments. I’d like to thank Commissioner Sapienza for entrusting us with this important work.”

“This newly completed storm sewer extension will make a real difference for the residents in Bay Terrace, residents who have battled serious flooding issues for many years,” said Borough President James Oddo. “Thank you to our partners at DDC and DEP for their work completing this much needed project. No longer will these South Shore residents risk getting trapped in their cars during a rainstorm.”

“I'd like to thank DEP and DDC for their hard work and coaction that will have a lasting impact on hundreds of Staten Islanders,” said Council Member Joe Borelli. “These necessary infrastructure upgrades will mitigate severe street flooding and improve water service reliability for our constituents.”

“I have lived in Bay Terrace for most of my life and the lack of infrastructure has been an ongoing issue for decades,” said Assembly Member Nicole Malliotakis. “This project will alleviate the chronic flooding that the overpass has experienced and we are grateful for the city’s investment.”

As part of the project, 1,200 feet of new storm sewers were installed and 500 feet were replaced along portions of South Railroad Avenue, Bartow Street, O’Gorman Avenue, Durant Avenue and Redgrave Avenue. Work also included the addition of seven new catch basins and the replacement of three others in the area to better capture stormwater and direct it to the new storm sewers, helping to reduce street flooding and improve drainage. The project also constructed an underground sewer chamber under a Parks Department greenstreet at the intersection of South Railroad Avenue and Amboy Road. Once finished, 51 species were replanted in the greenstreet, which now features a steel-faced curb and a crosswalk cut-through.

Additionally, 3,000 feet of water mains, ranging in diameter from 8 inches to 20 inches, were replaced. The new pipes are made of concrete-lined ductile iron, which is more resilient and less prone to breakage than the cast iron pipes that were replaced. Three new fire hydrants were also added and eight were replaced to ensure firefighters have ready access to the City’s water supply during emergencies.

While the roads were open for construction, 1,450 feet of new sanitary sewers were also replaced, with another 50 feet newly installed. As part of the final street restoration, 8,000 square feet of sidewalks, 1,800 feet of curbs and 11,000 square yards of roadway were reconstructed. The new curbs and sidewalks were leveled to help guide stormwater to the area’s new catch basins and to ensure adequate drainage during storms. Throughout the project area, 28 new trees were planted.
