Culvert replacement project leads to closure on portion of Snoqualmie Valley Trail, Sept. 22

A project to replace an aging, undersized stormwater culvert means that a portion of King County’s Snoqualmie Valley Trail will be closed Sept. 22.

The King County Water and Land Resources Division will be replacing the undersized culvert that carries Deer Creek as the stream crosses underneath the trail near the intersection of State Route 203 and Northeast 124th Street near Duvall.

The trail will be closed from north of Northeast 124th Street to the southern end of Duvall Park, located off the Carnation-Duvall Road.

During high rainfall events, Deer Creek swells to such a size that can’t be contained within the culvert. As a result, the creek flows over a nearby road and floods an adjacent farm field. Fish that have been swept into the field by the high flows are often left stranded there once flows recede.

The new culvert is large enough to provide additional capacity for the creek during high flows.

The culvert replacement project is expected to cost $55,000, and funding is provided through King County Surface Water Management capital improvement project funds.

The Snoqualmie Valley Trail is King County’s longest trail, running alongside the Snoqualmie River for more than 31 miles, from Duvall southeast to Rattlesnake Lake and Seattle’s Cedar River Watershed above North Bend.
