The Jersey City Municipal Utilities Authority (JCMUA) recently completed stormwater improvements that are being funded with approximately $6.6 million in loans from the NJ Water Bank, a joint low-rate funding program of the DEP and the NJ I-Bank. This project qualified for principal forgiveness totaling $1,328,974 as it addressed damage from Superstorm Sandy and improved resilience for future storms. Another component of the project addressed CSO issues with green infrastructure, qualifying for additional principal forgiveness funds. Including interest cost savings, total savings for this project is estimated to be $3.4 million, over the 20-year term of the loan or 51% of the total project cost. In addition, this project created an estimated 79 direct construction jobs.
The project included the installation of emergency generators at the east and west side pump stations, their connection to the electrical systems, concrete foundations, storm drains, water main and hydrants, paving, and removal of oil storage tanks. The green infrastructure portion of the project included the replacement of deteriorating sidewalk with pervious sidewalks to recharge groundwater. Two existing downspouts were directed into six pre-cast downspout planter boxes equipped with perforated underdrains that discharge to approximately 1,760 square feet of pervious concrete sidewalk that intercept, treat and filter stormwater runoff from the rooftop. Approximately 8,540 square feet of porous asphalt parking spaces were installed to intercept, treat and filter stormwater runoff from the parking lot. Two rain gardens were installed in front of the JCMUA building to capture stormwater runoff from the adjacent parking lot. Three rain gardens were installed along NJ Route 440 to intercept, treat and filter stormwater runoff from part of the roadway.
Steven M. Fulop, Mayor of Jersey City applauded the project noting, "This is a smart project. For very little money, we have diverted water from our combined sewer system with green engineering techniques and qualified for principal forgiveness in the process. The result is reduced stormwater overflow, improved resiliency and savings of over 50% in the long run. This project is an excellent example of our commitment to better manage our waste water, improve resiliency in case of future storms and reduce risks to public health and the environment. This project accomplished all that at an affordable price that will save our ratepayers money over time."
This project was designed by Remington Vernick Engineers and the Rutgers Cooperative Extension Water Resource Program. It was constructed by Carbo Constructors Corp. and Montana Construction Corps, Inc.
