The Cheverly East Park Hub borders Tributary 4, with a wooded area adjacent to Route 50. It also has some very old trees and a well developed shrub layer. Removal of the invasive plants could allow the previously rich herbaceous layer to recover. Tributary 4 is another dead creek bereft of aquatic life, largely due to the fact that it derives most of its input from several outfalls channeling polluted water from town streets. Some creek restoration has been conducted by the Army Corps of Engineers for M-NCPPC. Additional tree buffer will help filter pollutants and prevent erosion of the stream banks.
