This project would improve the confluence of the remnant Black River with the Green/Duwamish as an emergent marsh, increasing nutrient productivity for the surrounding system and improving access for salmonid refuge and rearing.

The project is located along the lower Black River, which empties into the Green River at rivermile 11.0 on the right bank. The project would remove approximately 200 cubic yards of fill material from the left bank of the Black River at the confluence with the Green River, just west of the railroad tracks. This small area would then be planted with appropriate native marsh vegetation and a few large stumps with root wads would be placed to provide cover. A 50-foot wide riparian buffer would be created along the banks of the Black River from the Black River Pump Station to the confuence.

This is a Green/Duwamish Ecosystem Restoration Project.

The side has significant infrastructure that will make site rehabilitation challenging. Invasive plant species now dominate the site. In 2005, volunteers organized by a Renton resident began planting native trees and shrubs on the south bank of the Black River just west of the Black River Pump Station.
