Amazon appears to be deepening its footprint in the Treasure Valley with plans for a substantial new fulfillment facility south of the Boise Airport, according to a zoning application filed in Ada County. The proposed 250,000-square-foot building would serve Amazon’s rapidly expanding same-day and sub-same-day delivery network, which the company rolled out to southwest Idaho residents earlier in 2026.
What the Application Shows
Salt Lake City-based Asilia Investments submitted the application to construct the facility on land currently owned by Adler Industrial. The development is described in the filing as a “fulfillment center and distribution” operation, and site plans include a designated “Flex” area tied to Amazon’s delivery driver program. The building is also designed with specialty grocery delivery ramps, pointing toward Amazon’s sub-same-day grocery ambitions in the region.
Asilia describes the project as a concrete tilt building. In its own words, “This project will feature a concrete tilt building designed to house a diverse range of goods destined for distribution.” The firm lists six clients and notes it has completed four Amazon industrial construction projects in the region.
To move forward, the property requires a zoning change from I-1 to I-2 — a shift that would allow around-the-clock operations. That detail underscores how Amazon and its development partners envision running the facility: a 24-hour distribution hub serving same-day delivery demand across the Boise metro area.
Context: Amazon’s Growing Treasure Valley Presence
The new proposal fits a pattern of aggressive Amazon infrastructure investment across the region. The company already operates smaller facilities in Boise, Meridian, and Nampa. Its largest regional presence is the massive Project Bronco warehouse in Nampa, which spans 2.5 million square feet. An air cargo hub is also in development at Boise Airport, and a drone delivery facility is reportedly underway in Nampa as well.
The proposed site is not far from where Amazon previously attempted a far larger project. In 2022, the company put forward Project Dove — a 1.33-million-square-foot facility on nearby Pleasant Valley land, part of a nearly 2,000-acre development area. The project received an $86.4 million building permit before the permit was later voided, and the project ultimately did not proceed. The current 250,000-square-foot proposal is considerably more modest in scope, suggesting Amazon may be pursuing a more targeted approach to serving the Boise market rather than the sweeping campus-style development envisioned four years ago.
Impact on Ada County’s Economy and Workforce
For Ada County residents and businesses, a new Amazon fulfillment center near the Boise Airport would represent a significant economic signal. Same-day delivery infrastructure requires a substantial local workforce — including warehouse staff, delivery drivers, and logistics support personnel — and expanded Amazon operations have historically generated steady employment across wage ranges in communities where they operate.
The Boise metro area has seen considerable commercial and industrial growth in recent years as new residents and businesses continue arriving in the Treasure Valley. Faster delivery options benefit local consumers and small businesses alike, and Amazon’s continued investment suggests the company views the region as a long-term growth market. The Boise Metro Chamber recently recognized local business excellence finalists, reflecting the broader momentum in the area’s private sector.
A rezoning approval would also set a precedent for the surrounding industrial corridor, potentially attracting additional logistics and distribution tenants to the south Boise area. Adler Industrial’s request to move from I-1 to I-2 zoning would give the site significantly more operational flexibility, a change neighbors and area commuters may want to monitor as the application advances.
What Comes Next
The rezoning application will need to work through Ada County or City of Boise review processes before construction can begin. Residents who live or own property near the Boise Airport corridor should watch for public hearing notices, which are typically posted by the city or county planning department. Those with questions or concerns about the I-2 zoning request can contact the City of Boise Planning and Development Services department for updates on the application’s status.
No timeline for a decision or construction start has been publicly announced. As the region continues drawing new retail and logistics investment — from restaurant chains expanding into Meridian to major distribution players eyeing Ada County land — the outcome of this application will be one to watch for anyone tracking Treasure Valley economic development.
