Costco has withdrawn its application to build a warehouse store in Eagle, pulling the plug on a project that would have brought a 166,000-square-foot store, 912 parking spaces and a gas station to a site off Hill Road. The company walked back its plans on Oct. 16, according to Eagle officials, just weeks before Costco is set to open a massive new store across the valley in South Meridian.
No Explanation Given for the Reversal
Eagle spokesperson Laura Williams said the city was not given a reason why Costco abandoned the application, as reported by idahopress.com. Williams told the Idaho Statesman that the city had not heard from Costco in three months before the withdrawal came through. Despite the silence, Williams said she remained optimistic that a Costco store was still in Eagle's future, though she offered no details to back that hope up.
The proposed site sat on a 27-acre parcel off Hill Road between Highway 55 and North Horseshoe Bend Road, according to kivitv.com. Williams told the station the city has been given no information nor has any knowledge whether Costco is considering a different location within Eagle or the surrounding area. Costco first confirmed it was exploring the site as early as December 2025, the station reports, meaning the project had been in the works for roughly ten months before it collapsed.
What the Eagle Project Would Have Looked Like
Had it moved forward, the warehouse would have included a gas station and parking for 912 cars, according to plans detailed by boisedev.com. The site plan called for a primary entrance roundabout on Hill Road, with a second roundabout planned to the east at the intersection of Horseshoe Bend Road and Hill Road. The same traffic analysis projected the development would add 6,985 new vehicle trips at build-out in 2027, a figure that fed into concerns from neighbors near the site, who raised worries about traffic, safety and quality-of-life impacts, per the KIVI-TV report.
Had it been approved, the project could have marked Costco's fifth location in the Boise area, per BoiseDev's earlier reporting. The company already controlled 9.7% of all grocery sales in the Boise market as of 2022 CSG data cited by the same outlet, underscoring how much ground Costco has already carved out in the Treasure Valley even without a presence in Eagle itself.
South Meridian Store Opens Nov. 5
While Eagle's plans fell apart, Costco is nearly finished with its fourth and largest Treasure Valley location, set to open near the Kuna-Meridian border. The South Meridian store, at 203 E. Tower Lane near Lake Hazel and Meridian roads, is scheduled for a grand opening and ribbon-cutting on Nov. 5, according to the Idaho Press's reporting on the opening date. The warehouse will exceed 200,000 square feet and feature 16 fuel pumps alongside nearly 1,000 parking stalls, per the same account — notably larger than the scrapped Eagle proposal's 166,000 square feet, 912 spaces and single gas station.
The new location will be the second Costco in Meridian, the fourth in the Treasure Valley and the eighth in Idaho, the Idaho Press reports. BoiseDev has described the South Meridian warehouse as one of the larger Costco stores in the world from a square-footage standpoint, owing in part to an included fulfillment center. For Eagle residents who had been tracking the Hill Road proposal since late last year, the contrast is stark: one Treasure Valley Costco is about to open its doors, while another remains, for now, an application withdrawn without explanation.
