Pima County consults tribal nations on possible Costco site near I-10.

Pima County is starting government-to-government consultation with tribal nations about possible development of county-owned land at Sunset Road and Interstate 10 for a Costco store.

The consultation will allow tribal nations to identify concerns and cultural values related to the proposed disposition and potential development of the approximately 56.66-acre property on the southwest corner of the interchange.

County officials said the process is consistent with Pima County Board of Supervisors Policy C17.1, which requires consultation with tribal nations.

The property sits within a highly significant archaeological site containing extensive and deeply buried cultural deposits dating back more than 3,000 years.

The site includes evidence of some of the earliest irrigation agriculture in North America north of Mexico, later Hohokam settlements, and previously documented ancestral human remains and footprints.

Pima County's Cultural Resources and Historic Preservation Office has longstanding knowledge of the site and is responsible for advising both the county and Costco regarding applicable cultural resources requirements.

County officials said they will keep the Board of Supervisors informed as tribal consultation, the county's enhanced due diligence review, and discussions with Costco progress.
