To install the headwall, Dungeness Construction, Kirkland's contractor, will build a temporary access road and, after construction will re-plant it with more than 2,000 ferns, elderberry and other native plants and shrubs.
INFORMATION & UPDATES Update (Dec. 9, 2019) --
Dungeness Construction is completing the final portions of the project, like installing plants, replacing fences, and smoothing the trail adjacent to the new headwall.

WHAT: Dungeness Construction begins work in late-July on repairs to a 24-inch culvert, the outfall of which is eroding a small section of the Cross Kirkland Corridor’s foundation north of Crestwoods Park. Crews will install a manhole and build a stream channel with check dams to dissipate the impact of the water as it flows from the concrete culvert, onto the Cross Kirkland Corridor’s foundation and down the hillside.
The contractor will also build a concrete headwall to support the trail’s foundation. When complete, Dungeness will plant the surrounding areas with native vegetation, such as Sword Ferns, Red Elderberry and Western Red Cedar. The project will require a 14-day trail-closure, between Northeast 100th Street and 111th Avenue Northeast.
WHEN: Dungeness plans to close the trail from Aug. 19 to Sept 6. The closure will be in effect 24 hours a day, seven days a week. Dungeness will not allow any travel along the closed section of trail. Crews will work eight hours a day, between 7 a.m. and 5 p.m.
WHAT TO EXPECT: Dungeness Construction will establish a walking and bicycling detour route.
