According to King County Road Services Division, two lower Snoqualmie Valley, flood-damaged roads will get some much-needed repairs. Repair work on David Powell Road and Fish Hatchery Road is planned for summer 2017, but will be done at different times to reduce traffic impacts on the area.
Road Services stated about 300 linear feet of David Powell Road, about a mile southeast of Preston-Fall Road, has chronic problems during floods and storm so the county will build a rock buttress wall; replace a catch basin and culvert under the road; repair the roadway, shoulder, and slope; install new guardrail along the river side of the road; and plant native vegetation.
One lane of David Powell Road will remain open throughout the approximate 4-week project.
Over on Fish Hatchery Road, about 180 feet on the river side of the road developed small failures along the southeast shoulder due to river scour and storms. A section of the shoulder also dropped about six feet, leaving a near vertical cut along the south edge of the road.
Subgrade under two sections of the roadway will be rebuilt and then a new guardrail installed. Utilities will be moved before construction begins.
Unfortunately, the work requires this section of Fish Hatchery Road to be completely closed for about three weeks, but Road Services will place a detour around the construction.
Funding for both projects is administered by King County Department of Natural Resources and Parks Water and Land Resources Division’s River and Floodplain Management Section.
