Flagstaff Road Flood Recovery Reconstruction

FLAGSTAFF ROAD CONSTRUCTION COMPLETE. NOW OPEN 24-7-365

Background:

During the 2013 flood event, Flagstaff Road was badly damaged. The most extensive damage occurred approximately 1,000 feet up from Gregory Lane, where a major slope failure washed away a 200-foot section of the roadway going up Flagstaff Road.

Temporary measures were put in place following the flood, which provided one-lane, traffic signaled-access to residents and visitors. Permanent repairs are necessary to ensure long-term safety for all users of Flagstaff Road.

Repairs:

A contractor constructed a 200-foot long bridge in the uphill lane that spans the washed out area and more. A retaining wall was also built on the uphill side to help strengthen the hillside and help catch any material that slides from above.
