Pima County considers possible data center regulations

Pima County is actively considering implementing new data center restrictions within its zoning code, a move that comes shortly after the county supervisors enacted a 100-day moratorium on new data center developments.

The proposed rules, currently in draft form, would mandate several key requirements for data centers. These include the use of closed-loop water cooling systems to promote water recirculation and reuse, certified access to adequate water and energy supplies, and buffer yard requirements. Specifically, draft rules suggest a minimum 200-foot buffer yard with vegetation and decorative walls when data centers are adjacent to residential or mixed-use areas. Noise limits at property lines for projects near residential zones would be capped at 55 decibels.

Pima County Supervisor Jennifer Allen stated her opposition to data centers in the community but emphasized the necessity for specific regulations. Joseph Fett, who attended an open house on the topic, voiced support for common-sense regulations, advocating for requirements such as closed-loop cooling and noise limits, especially in proximity to residential areas.
