Project description: Clackamas County has received Federal Emergency Relief Program (ERP) funds to stabilize the roadway and slope on South End Road at Milepost 3.8 (near Coffee Creek). The road was damaged in March 2017 as a result of heavy rains. A state emergency declaration, which included Clackamas County, was signed by the governor that allows Clackamas County to be eligible for the federal funding.
Clackamas County constructed temporary repairs to these areas in the spring of 2017. A more permanent solution is required to help stabilize the slope. We expect that solution will consist of a retaining wall and reinforcement of the roadway embankment. In accordance with state and federal requirements, we have hired a firm to design these improvements.
Current activities: Additional geotechnical explorations and survey will occur February 17th through the 19th. The additional explorations are needed to better define the subsurface conditions and identify potential retaining wall limits to stabilize the slope.
Schedule: Project design is underway and will be completed in the winter of 2020, with construction planned for 2021.
Project impact on traffic:
- During spring-summer 2019, there will be occasional lane closures for surveying, geotechnical explorations and environmental assessment work.
- A full road closure is expected during construction in 2021.
