40 percent of Jersey City is within a FEMA flood zone and 62 percent of the city is covered by impermeable surfaces such as buildings, concrete and asphalt, which block water from entering the ground. Jersey City’s sewer system is primarily combined, which means that water from storm drains in the streets joins with wastewater from buildings in the same sewer pipes. When these sewer pipes are filled beyond regular treatment capacity (such as during heavy rainstorms), the excess water, mixed with partially treated sewage, overflows through one of the 21 combined sewer outfalls into the Hudson River and the Hackensack River.
In an effort to reduce local flooding and limit pollution of of waterways, Jersey City made 2017 the ‘Year of Water’.
The ‘Year of Water’ was a year-long storm water management initiative that focused on:
1) education and awareness; 2) community action; and 3) building a sustainable foundation for storm water management projects.
Among those activities were:
Other initiatives related to the Year of Water effort include the creation of resiliency planning documents, the introduction of a revised tree ordinance and landscaping requirements, and the development of city-wide forestry standards.
Going forward, the Office of Sustainability and its partners will continue working to ensure that green infrastructure is included in future development and to ensure the City’s water infrastructure is prepared to meet residents’ needs for decades to come.
