In a recent government meeting, officials outlined a significant infrastructure project aimed at revitalizing the Deschutes River area, which includes the construction of a new 5th Avenue Bridge and extensive ecological restoration efforts. The project, which spans from the south end to the 5th Avenue Bridge at the north end, will feature vehicle lanes, pedestrian pathways, and bike lanes, enhancing accessibility for commuters.
A key component of the project involves dredging approximately 500,000 cubic yards of sediment that has accumulated in the river channel since the construction of the dam in 1951. This sediment removal is expected to restore the main channel of the Deschutes River, which has been adversely affected by sediment deposits of around 32,000 cubic yards annually. The dredged sediment will be repurposed to create new salt marsh habitats, benefiting salmon and other species reliant on these ecosystems.
The project also aims to restore public access to the water body, which has been closed to recreational use since 2009. Plans include the development of boardwalks, new access points for hand-carried boats, and fishing opportunities, responding to community interest in restoring recreational activities.
In addition to the bridge construction, the project will replace the Percival Cove Bridge and improve over 70 outfalls discharging into the project area. The existing 5th Avenue Bridge and dam will ultimately be removed to facilitate tidal flow restoration, allowing sediment from the Deschutes watershed to move freely into West Bay.
Addressing concerns about invasive species, officials noted that while ten of the twelve aquatic invasive species in the area would be eradicated, two species would remain but be significantly controlled. A decontamination process will be implemented for users accessing the water to prevent the spread of these species to other bodies of water.
Financial discussions highlighted that the state will bear the costs associated with the project, with further cost estimates expected as the design progresses. Local government participation and ongoing maintenance costs were also addressed, ensuring that the financial responsibilities are clearly defined as the project moves forward.
Overall, the meeting underscored the project's dual focus on infrastructure improvement and ecological restoration, aiming to create a sustainable environment that supports both community recreation and local wildlife.
