The Long Branch Tributary at Long Branch Falls Park project restored approximately 670 linear feet of stream within the Accotink Creek watershed. The stream channel was enhanced and stabilized using natural channel design elements. Existing erosion damage was repaired and future water quality has been improved. The project included channel realignment, in-stream rock structures, log structures, constructed wetlands, wood habitat clusters, deer exclusion fence, removal of invasive plants and the re-establishment of the riparian buffer with native species.
