Sustainable Cherry Hill, NJ Tree Foundation, Center for Environmental Transformation and Camden County Municipal Utilities Authority (CCMUA) are collaborating to spruce up the five-acre, public Liney Ditch Park, in Camden’s Waterfront South community, from 8:30 to 11:30 a.m., July 26.

Although this park serves as a recreational space for hundreds of children each day, it is located adjacent to the county’s waste water treatment plant and numerous industrial companies, which means it is disproportionately affected by air pollution and unpleasant odors. In October 2013, more than 100 new trees were planted by a group of dedicated partners as part of a shelterbelt surrounding the CCMUA Waste Water Treatment Plant.

Volunteers will help prune, mulch and stake (if needed) the trees, as well as helping clean up overgrowth, trash and more. Residents, individual or groups are welcome to join but must preregister. Refreshments will be served. Children 4 years old and older are welcome with supervision.
