The property is located at the southeast corner of Northeast 20th Avenue and Northwest 139th Street. Costco's plans for the 17.6-acre site have been to build a 142,000-sf building on the site along with a tire store and a gas station. The county's computerized estimates reportedly show that Salmon Creek Avenue traffic to and from the warehouse store would slow to well below the acceptable limit of 22 mph. The road currently serves Washington State University-Vancouver, but a new hospital is also proposed along the route.

Costco previously volunteered to make more than $1 million in traffic improvements to nearby streets, such as widening a nearby busy Interstate 5 exit ramp as well as Northwest 139th Street. The city's estimates, however, found that even with the traffic improvements Costco could not meet the mph standard.

Across the Columbia River in Hillsboro, OR, Dirt is moving at the corner of Northeast 48th Avenue and Cornell Road for an eventual 148,663-sf Costco warehouse. The company says it will start erecting the actual building next spring and open for business next fall.
