Flood Warning System

As many in Hoboken experienced, Hurricane Ida inundated the City with over 6.5 inches of rain in a very short amount of time, causing flooding in basements and homes; some of which had never experienced flooding before. Unfortunately, these types of severe storms are only projected to occur more frequently in the years to come.

Automated Flood Warning System

To help protect the community and deter unadvised and potentially dangerous vehicular travel during severe storm events, the City will install an automated flood warning system at some of the most flood-prone intersections in western Hoboken in fall 2022.

These improvements will safely close flood-prone intersections and roads during storm events to prevent damage to property and injury and also reduce the City’s resources and costs associated with flooding events.

The project is funded by a federal grant, at no cost to Hoboken taxpayers.

Flood Warning System Components

The automated barricades and associated warning signage will be solar-powered and activated by real-time flood monitoring sensors within catch basins through a cloud-based system called Contrail by OneRain. This system will allow City officials to see water levels in real-time and close the gates when water is on the roadway.

The system will include 5 master gauging stations; 11 corresponding remotes with warning signs, flashing beacons or barricades; and 1 base station.

Avoid Flood-Prone Areas

The Office of Emergency Management posts “No Parking Signs” in low-lying, flood-prone intersections to advise residents where vehicles should not park during forecasted intense rainfall events. Currently, wooden barricades are manually deployed to prevent travel through flooded intersections.

Mitigate Flooding in Hoboken

Learn about Hoboken’s efforts to mitigate rainfall flooding.

The City has opened two resiliency parks since 2017; the Southwest Resiliency Park and the 7th & Jackson Resiliency Park, which can detain a combined total of 670,000 million gallons of stormwater during heavy weather events. The City is scheduled to open its third and largest resiliency park, the Northwest Resiliency Park, in the spring of 2023. It will detain up to 2 million gallons of stormwater and provide over 5 acres of open space.   

The City continues to engage in a community design process to double the size of the Southwest Resiliency Park at Block 10 at Observer Highway and Harrison Street. The City and project team will present a final proposed concept design on the above-ground active recreation and below-ground stormwater infrastructure to mitigate area flooding this fall.  For more information on the Southwest Resiliency Park expansion, go to www.hobokennj.gov/swparkphase2. 

Learn how you can reduce flood risk on your property by reviewing the Resilient Building Design Guidelines Addendum. After months of work engaging with stakeholders, experts, and the community at large, the City released this comprehensive resource of strategies to guide property owners as they prepare their buildings to better mitigate flooding, on their properties, caused by severe rain events. It outlines strategies to reduce an individual property’s flood risk, guides property owners through the City’s permitting and approval process, and provides key contacts and flood preparation tools to know before a storm event strikes.
