The Centreville Green Ponds 1 and 2 are located within the Centreville Green Subdivision; Pond 1 is located off Lee Highway and Pond 2 is located off Canada Goose Court within the Little Rocky Run Watershed. The project consisted of retrofitting the existing two ponds to improve water quality and storage volume. Improvement will increase the residence time of the ponds and provide enhanced water quality benefits. Retrofitting the Centreville Green Ponds allows for the facilities to provide a reduction of 10.7 pounds of total phosphorous, 82.3 pounds of total nitrogen, and 8,622.9 pounds of sediment per year.
