Maricopa is considering new zoning rules for data centers that could determine where the facilities are built, how close they can be to neighborhoods and how their operations affect nearby residents.

The proposed zoning code amendment would establish development standards addressing community concerns while allowing for future data center development opportunities, according to the city.

The proposal covers several areas, including where data centers could be located, required separation from residential areas, noise generated by cooling equipment and backup generators, and requirements related to water consumption and conservation.

It would also address electrical infrastructure information, building height and placement, and standards for architecture, landscaping, screening and public art.

The proposed regulations come as data centers are popping up around Pinal County, including two near Maricopa. Copia Power’s 500-acre Harquahala center south of the Ak-Chin Indian Community near White-and-Parker and Teel roads was approved by the Pinal County Board of Supervisors last year and another data center is planned near Stanfield. 

Residents can review the proposed regulations and share feedback during a public open house Nov. 10 at 6 p.m. at Maricopa City Hall, 39700 W. Civic Center Plaza. City staff and subject matter experts will be available to answer questions about the proposed requirements and how they are intended to address community concerns.

The open house is the first step in a series of public meetings before the proposed amendment reaches City Council.

The Planning and Zoning Commission will discuss the proposal Nov. 23, followed by a meeting Dec. 14 to consider the amendment and potentially take action.

City Council is scheduled to hold a public hearing and consider the proposal Jan. 19, 2027. All meetings begin at 6 p.m. in the City Hall Council Chambers.

Residents can review the proposed ordinance online. Questions and comments can also be emailed to the Development Services Department at DSD@Maricopa-AZ.gov.
