There is an active landslide on Scoggins Valley Road at the north end of Hagg Lake. We will stabilize this section of road by installing a retaining wall and replacing a culvert.

We began construction on a group of projects to improve the perimeter road around Hagg Lake in 2015. This group of projects included stabilization of five active landslides, culvert replacements, paving and guardrail upgrades. This is the final project in that effort.

Construction start (expected): June 2022

Construction finish (expected): January 2023
