Grant Road Underpass Reopens, Plus New Rules for Data Centers
Tucson, AZ · August 6, 2026
Puddles are still drying from yesterday evening's monsoon shower, but drivers heading west get a welcome relief on the roads this morning.
The Lead
Following months of public debate over local water and energy strain, elected officials approved sweeping new zoning regulations for large-scale data centers on a 6-1 vote Wednesday evening. The updated rules establish standard public review processes, require developers to perform comprehensive noise studies, and mandate clear disclosures regarding energy and water usage. Facilities must also observe larger setback distances from residential neighborhoods and meet strict environmental landscaping criteria, including options for off-site land conservation.
The decision arrives as desert communities across the region balance growing technology infrastructure demands against severe Colorado River water allocations. Under the new code, any future data center project will require neighborhood coordination, public hearings, and approval from the zoning examiner before reaching the council floor. The regulations take effect on September 5.

Spotlight & Story
- The Sonoran Hot Dog
- In 1993, Daniel Contreras parked a trailer on South 12th Avenue, dressing franks in bacon, pinto beans, and grilled onions tucked inside soft bolillo rolls. That roadside stand grew into El Güero Canelo, turning a borderland street food into a defining culinary ritual.
