Planning Commission approves significant zoning and general plan amendments for data centers

In a recent Phoenix City Council meeting held on July 2, 2025, significant discussions centered around proposed amendments to the city's general plan and zoning ordinance. These amendments aim to address the growing demand for data centers while ensuring public health and safety standards are met.

The meeting highlighted two main components: the general plan policy amendment and the zoning ordinance update. The general plan amendment is designed to evaluate future special permit requests and major amendments to Planned Unit Developments (PUDs). It emphasizes location criteria and design standards, which are crucial for maintaining the integrity of community development.

A key aspect of the zoning ordinance update is the introduction of data centers as a listed use. This includes a definition for data centers, the requirement for a special permit for their establishment, and performance standards aimed at mitigating potential public health risks associated with these facilities. The text amendment also outlines specific site and design requirements, including building and landscape setbacks.

Prior to the public hearing, city staff conducted three stakeholder listening sessions to gather input. The general plan amendment received mixed feedback from village planning committees, with 10 out of 15 committees recommending approval or conditional approval, while four committees suggested denial. The text amendment faced similar scrutiny, with seven committees recommending modifications or conditional approval and another seven recommending denial.

The Planning Commission ultimately approved both amendments with modifications, including updates to utility agreements and noise standards. Notably, the commission clarified the types of utility lines applicable to the amendments and adjusted the timeline for utility service agreements.

Mayor Steff expressed support for the amendments, recommending their approval based on the Planning Commission's recommendations. The council also discussed the implications of Proposition 207, which allows property owners to seek waivers for claims of diminished property value due to new land use regulations. This aspect of the discussion underscores the ongoing tension between development needs and property rights.

As the council moves forward, the approval of these amendments is expected to shape the future landscape of Phoenix, particularly in accommodating the increasing demand for data centers while balancing community concerns about health and safety. The next steps will involve finalizing the ordinance and addressing any outstanding issues raised during the public hearing process.
