Marana Planning Commission Eyes Stricter Rules for Data Centers, Including New Noise and Shutdown Requirements

New rules governing where and how data centers can operate in Marana — covering noise limits and what happens when a facility closes — are the centerpiece of Wednesday's Planning Commission meeting. Commissioners will also decide whether to cancel their holiday-season meetings in November and December.

New Noise Rules and Decommissioning Requirements Would Reshape How Marana Regulates Data Centers

Public Hearing | Item B.1

The commission will hold a public hearing on proposed changes to Section 17-6-13 of Marana's Land Development Code — the section that specifically governs data centers. Two changes are on the table: tighter noise-attenuation rules that would "clarify and add additional requirements" for how facilities must muffle the constant hum of cooling fans and electrical equipment, and an entirely new paragraph requiring data centers to have a formal decommissioning plan for when they eventually shut down.

This item sits at the intersection of two of Marana's most closely watched issues. The town has been embroiled in a data center rezoning controversy that has already produced lawsuits over rejected referendum petitions, meaning any adjustment to the underlying land-use rules carries real legal and political weight. For residents who live near existing or proposed data center sites, the noise provisions are directly personal — industrial cooling equipment can generate sustained sound levels comparable to highway traffic — while the decommissioning rules address what happens to large, specialized facilities if an operator walks away, a question that affects neighboring property values and long-term land use. Because this is a public hearing, residents can speak on the record before the commission sends its recommendation to the Town Council.

Commission Could Cancel Two End-of-Year Meetings, Affecting Project Timelines

Item D.1

Commissioners will discuss whether to cancel or reschedule their November 25 and December 30 meetings, both of which fall close to major holidays.

While this may sound like a housekeeping matter, the decision has practical consequences for developers, applicants, and residents who are waiting on land-use decisions. Canceling both meetings would leave the commission without a scheduled session for roughly two months — from late October through early January — potentially pushing rezonings, plats, and development plan reviews into 2027. Anyone tracking a pending application before the commission should pay close attention to how this vote goes.
