Council-Regular Meeting — October 20, 2026
Marana strengthened its data center code: new low-frequency dBC noise limits, a 50 dBA nighttime cap near homes, 24-hour ambient noise baselines, and financial assurances (with 15% contingency) required before construction to cover decommissioning. Council Member Cavanaugh voted no, doubting the rules can actually be enforced against billion-dollar operators.
Planning Commission — August 26, 2026
After resident concerns about data centers, the Town hired an acoustical engineer to review its noise rules. An amended ordinance is expected before the Commission next month.

Council-Regular Meeting — January 6, 2026
Two huge data center campuses totaling about 611 acres were approved near the Pinal County line after a marathon public hearing. Proponents tout billions in investment, 4,200 construction jobs, 400 permanent jobs and $145 million in projected town tax revenue over ten years; opponents worry about regional water and power impacts, generator emissions, and transparency gaps.

Data center code text amendment (Ordinance No. 2026.018)
Future data centers — including Luckett Road — will face stricter noise monitoring, annual studies for five years, and bonds guaranteeing cleanup if the facility shuts down.
Luckett Road North Specific Plan (data center)
Adds a second 300-acre campus to the overall 600-acre data center plan, roughly doubling regional construction and permanent job potential and TEP-served power demand of 550-750 MW.
