Costco Confirms 5th Store for Treasure Valley in Eagle Idaho

A new Costco Wholesale warehouse is seeking opening approval in Eagle, Idaho. Before any construction crews arrive, however, the parcel must be rezoned from its current mixed-use classification, originally assigned for a defunct development called Quarry Village, to a commercial designation, a request that now rests with Eagle planning officials. Traffic management stands as one of the most heavily scrutinized elements of the proposal, with engineering consultants projecting roughly 6,985 daily vehicle trips once the store reaches full operations in 2027, prompting a multi-pronged roadway response that includes two high-capacity roundabouts, one providing primary site access on Hill Road and another at the Horseshoe Bend Road junction, alongside two right-in, right-out entry points fitted with dedicated acceleration and deceleration lanes, all developed in coordination with regional transportation agencies to accommodate the anticipated flow while maintaining safety for pedestrians and cyclists.

Situated near the Idaho State Veterans Cemetery, the chosen property would serve a rapidly expanding catchment area that includes Dry Creek Ranch, Avimor, and northwest Boise neighborhoods, while also offering a considerably shorter shopping trip for residents of Valley County and Horseshoe Bend who currently journey to the Meridian store for their bulk purchases.
