Data Centers in the Sonoran Desert:


What You Need to

Know Right Now


The Coalition for Sonoran Desert Protection has assembled essential updates on the rapid expansion of data center proposals across our region — and why these decisions matter for the future of our desert.


Two major developments highlight how quickly things are changing:

  • Pima County has approved a 120‑day moratorium on new data centers while officials evaluate long‑term impacts.
  • Pinal County has denied the rezoning request for the proposed La Osa Data Center, a project that would have pushed industrial development into a sensitive wildlife corridor. (Click here to review the letter of concern sent to the Pinal County Board of Supervisors by the Living Desert Alliance prior to their vote.)


These decisions underscore a growing reality: local codes alone can’t protect the shared regional resources that make the Sonoran Desert livable. Recent votes in Marana, Pima County, and Pinal County show how fragmented policies leave gaps that developers can exploit.


The Coalition is working to close those gaps by focusing on three core priorities:

  • Protecting our region’s water, a resource every community depends
  • Advancing cleaner energy solutions
  • Ensuring industrial projects are sited responsibly to avoid damaging critical habitat and wildlife linkages


This work is evolving quickly — and the Coalition is collaborating closely with partners to keep communities informed and engaged.

Help WMG Strengthen Tucson’s Large Quantity Water User Ordinance!


Tuesday, Sept. 8th, 7:00 pm to 8:30 pm


Watershed Management Group (WMG) needs your help as Tucson considers revisions to the Large Quantity Water User Ordinance — a policy drafted quickly last summer in response to the Project Blue data center proposal.


Mayor and Council are reviewing updates now, making your input both timely and impactful. WMG has developed a set of improvements designed to ensure that any future large water user does not deplete our groundwater or threaten the flow of our rivers.


Ward 6 Councilmember Schubert will open the session with remarks. WMG staff will then explain the history of the ordinance, why stronger protections are essential as Tucson faces ongoing drought and Colorado River shortages, and provide time for discussion and questions. They’ll also outline clear ways you can take action ahead of the September 22 Mayor and Council public hearing to help Tucson continue moving toward a hydro‑local future.

Masked CBP Agents Enter Tohono O'odham Lands


Customs and Border Protection agents entered Tohono O'odham Nation lands at 4 a.m. on Aug. 25 to begin pre‑construction work on segments of the border wall — activity tribal officials have consistently opposed.


The Nation reported that masked, armed CBP agents and contractors entered tribal lands without authorization. Because the Tohono O’odham Nation is a federally recognized sovereign nation, any federal activity on its lands requires clear communication and consent. When work begins without that authorization, it raises concerns about how federal agencies coordinate with tribal governments and whether established protocols are being followed.


This incident has prompted questions about respect for tribal authority, the protection of cultural and environmental resources, and the broader history of federal agencies engaging with Indigenous nations. For many community members, the issue is about the border policy itself and about ensuring that tribal sovereignty and long‑standing agreements are honored.

Activists Rally to Protect “Grandmother Cottonwood” in Lochiel, AZ


As shared in a recent newsletter, ongoing border wall construction has sparked an environmental protest in the San Rafael Valley, where activists and local residents have gathered around — and even atop — a centuries‑old cottonwood tree in an effort to prevent its removal. Three large cottonwoods have already been cut down as part of the project.


The protest began in late July in Lochiel, a small community on the U.S.–Mexico border adjacent to Sonora. Activists refer to the remaining tree as the “grandmother cottonwood,” estimating its age between 100 and 200 years. Standing just steps from the border wall, the tree has become a symbol of the region’s ecological and cultural heritage, as well as the community’s concern about the impacts of construction in this sensitive desert valley.
