Ahlquist, Coeur d’Alene Tribe unveil 920-acre Peregrine project near Micron
Peregrine pairs 774 acres of industrial land with 146 acres of commercial space beside I-84. The project is built to catch Micron suppliers and a fast-growing east Idaho corridor.
A 920-acre project at Interstate 84 and the Simco Road interchange is being positioned as one of the next big pieces of Idaho’s east-side growth, with 774 acres set aside for industrial and technology uses and 146 acres for commercial development. Ahlquist Development and the Coeur d’Alene Tribe unveiled Peregrine as a mixed-use site in Elmore County that is designed to serve Micron’s expansion in Boise while also attracting hotels, retail and service businesses tied to the same corridor.
The site sits off Exit 74 and is about 18 minutes from Micron’s Boise campus, a location Ahlquist is using to market the industrial park to semiconductor suppliers. Micron says it plans two leading-edge high-volume fabs in Boise, expects those projects to create more than 17,000 new jobs in Idaho and has scheduled DRAM output from its first Idaho fab to begin in 2027. That combination has turned freeway access and proximity to Federal Way in Boise into major selling points for the new development.
Ahlquist says the project has secured water rights for the site and that there are three letters of intent in place, although no tenants have signed yet. The company says the property can be leased, sold as land or developed as build-to-suit space depending on what an incoming user needs. On the commercial side, planners are discussing a truck-stop-type user, a car dealership, hotels and other retail and service tenants.
The Peregrine plan also sits near a separate resort casino proposal backed by the Coeur d’Alene Tribe and the Shoshone-Paiute Tribes, adding another layer of development pressure to the same stretch of land east of Boise. The tribes held a blessing ceremony at the proposed casino site on June 13, 2025, with more than 100 Shoshone-Paiute members at the land, and said they hoped to submit a fee-to-trust application to the U.S. Department of the Interior by late summer 2025. Their plan includes gaming machines, hotel rooms, a spa, entertainment and dining, along with a commitment to devote 5% of net gaming revenue to local schools and education programs.
For the Coeur d’Alene Tribe, Peregrine extends a business role far beyond North Idaho. Chief Allan said the project reflects the tribe’s long-standing commitment to economic development and its role in bringing the project to the Treasure Valley. With industrial land, commercial pads, housing and a nearby casino all moving in the same corridor, Simco Road and I-84 are becoming a new growth node in Idaho’s economic map.
