Prepare for detours amid Costco gas station expansion

Motorists should expect lane restrictions and detours near Costco in the months ahead, as the Issaquah-based warehouse giant expands the gas station at the flagship warehouse.
The changes should occur along Lake Drive and 10th Avenue throughout the summer.
In addition, the sidewalk along the north side of Lake Drive should be temporarily closed for most of June and some of July. Pedestrians can instead use the existing sidewalk along the entrance and exit to Costco on Lake Drive along the front of Costco and the tire center and to a sidewalk to connect to Northwest Sammamish Road.
Crews plans to post detour signs to guide pedestrians.
Several months ago, city planners approved Costco’s application to add two fueling islands to the gas station, and to expand the parking area adjacent to the warehouse for a net increase of 101 parking spaces, including upgraded handicapped parking stalls.
Plans call for about a quarter of existing wetland to be filled for the parking lot. Costco plans to mitigate for the impact by creating about 2.2 acres of wetland and 2.8 acres of wetland buffer on land east of Pickering Place and Issaquah Creek.
The gas station expansion is adjacent to the intersection of 10th Avenue and Lake Drive. The parking area expansion is located along Lake Drive east of 11th Avenue.
