The Ewing Township Municipal Fields rain garden was installed as a community demonstration project to intercept, treat, and infiltrate stormwater runoff from the adjacent parking lot.

This rain garden is part of an educational project sponsored through a grant awarded to the Ewing Green Team by Sustainable Jersey to lead and coordinate sustainability activities for Ewing Township. The Rutgers Cooperative Extension Water Resources Program worked with the Ewing Green Team to provide educational workshops that gave township residents the opportunity to learn how to be better stewards of the environment and to be involved in hands-on initiatives to take the first steps towards building a sustainable community. These workshops included two "Build a Rain Barrel" workshops and an "Introduction to Rain Gardens" seminar.

The Ewing Township Green Team, through its Rain Garden Committee, assessed sites throughout the Township with technical assistance from the Rutgers Cooperative Extension Water Resources Program and identified potential rain garden opportunities. Through these efforts, two rain gardens were installed in Ewing Township.

To address the water quality issues associated with increased stormwater runoff, demonstration projects like this rain garden are essential.

Type of Runoff Managed:

This rain garden manages stormwater runoff from the adjacent paved parking area.


The rain garden was installed in September 2011 by the Rutgers Cooperative Extension Water Resources Program staff and an undergraduate student intern. Staff from Greg's Landscaping, Inc., who completed the Rain Garden Training for Professional Landscapers, assisted with the labor of the rain garden by excavating and removing existing soil. They also amended the soil with a sand/compost mixture to allow for improved infiltration. Delaware River stone was used to stabilize the inlet and overflow to minimize erosion and slow stormwater flows entering and exiting the rain garden. A three-inch layer of triple shredded hardwood mulch was spread throughout the rain garden. The native plants installed in this rain garden were purchased from RareFind Nursery and J.K. Matthews Nursery LLC.

Approval to install the rain garden was granted by the Ewing Township Green Team. This rain garden was funded by a grant from Sustainable Jersey.
