This project would excavate a portion of the floodplain to reconnect the floodplain with the river between river miles 45.1 and 44.3, right bank. The project would excavate a connection between the wall-base side channel inlet and the mainstem and construct logjams to reinstate channel migration. This project also includes gravel addition, eradication of Japanese knotweed and other invasive species, and planting riparian vegetation.
This project is part of the Middle Green River "Blueprint" proposed by King County and is a Green/Duwamish Ecosystem Restoration Project.
The property is in public ownership.
Because of high use of this reach by recreational boaters, logjams would need to be engineered and placed in a manner that minimizes risks to boater safety.
Projects MG-3 and MG-4 may be combined for cost savings and efficiency.
Proper sequencing of projects MG-3 and MG-4 would need to be considered.
