Alpha Hill Project Update:

Construction expected to begin in January

King County has been working hard to begin this important water quality improvement project at Brightwater. To prepare for construction, trail users near Alpha Hill in the south trails area may see crews preparing the area, surveying the landscape, and installing environmental protections.

During construction, King County’s contractors will install a rock wall, fence, and landscaping on Alpha Hill. These improvements help control erosion, provide wildlife habitat, and protect water quality in nearby salmon-bearing streams.

Temporary trail closures in the south trails area are expected to begin in January and be in place for approximately three months. This keeps everyone safe during construction. Once construction is complete, this project will not change access to the three miles of maintained trails at Brightwater. 

Alpha Hill remains permanently closed to public access. Informal paths on the steep hillside can harm water quality by sending dirt into Little Bear Creek, a home to endangered salmon. 

Please follow posted signage and stay on open trails to protect the surrounding landscape.

If you’re looking for a new hill to climb nearby, check out: Norway Hill in Blyth Park, Hollywood Hill along the Tolt Pipeline Trail, or the Wetland Plateau Trail in the Paradise Valley Conservation Area.

Yellow caution tape covers the informal trail up Alpha Hill. A sign reads NOTICE AREA CLOSED FOR RESTORATION.

Alpha Hill is closed for restoration. Please stay on designated trails to protect the landscape.
