HOBOKEN CITY ROW GREEN INFRASTRUCTURE

The City of Hoboken recently closed on a $359,344 loan with the NJ Water Bank to construct Four right-of-way green infrastructure facilities recommended by the NJDEP Rebuild by Design Hudson River project will be installed on street segments that are adjacent to water main upgrades. Collectively, these green infrastructure measures will detain up to 10,000 gallons of stormwater from entering the combined sewer system during rainfall events.

The combined sewer system in Hoboken is overtaxed during rainfall events, resulting in CSO events up to five times per month. NHSA is developing a Long-Term Control Plan to reduce CSO events and improve water quality, as required by its individual CSO permit from NJDEP. These right of way green infrastructure sites will benefit CSO-reduction efforts because they allow for the capture of local street drainage during a rainfall event through a porous pavement surface and existing roadway curb gutter, store the rainfall runoff volume in a subsurface detention tank during the peak of the storm, and then discharge through a pipe with a backflow preventer into the combined sewer system. CSO reduction will improve water quality by preventing the discharge of untreated combined sewage into the Hudson River.
