DURATION: October 2017 – March 2018
STATUS: Completed
RIVERBANK LOCATION: Immediately downstream of North Park and the 2nd Street Bridge on the riverbanks adjacent to Waynesboro City Shops and the wastewater treatment plant
RIVERBANK LENGTH: 725 feet
ESTIMATED MERCURY INPUT FROM ERODING BANKS: 9.7%
OUTCOME:
Based on lessons learned during the Constitution Park riverbank remediation and because of steeper riverbank slopes in this area, several design changes were made. A more natural looking stone was placed at the base of the riverbank to more closely match surrounding river rocks more closely. Like the Pilot Bank, the stone was placed throughout the length of the remediated riverbank to enhance protection at the base of the bank.
The native trees and shrubs planted after construction are growing well and new trees are starting to grow from seeds deposited in sediment at the base of the bank. Although flooding has occurred, the remediated riverbank remained stable and no riverbank maintenance has been necessary to date.
The native vegetation that was planted is thriving and natural recruitment of other desirable plant species is becoming more established, with limited invasive species such as Japanese knotwood.
