Large-scale data centers may be developed only through adoption or major amendment of a Planned Area Development (PAD) or Planned Community Development (PCD); they are not allowed by right or through a special exception.

Projects must undergo a neighborhood meeting, enhanced public notice, a Zoning Examiner public hearing, and final consideration by the Mayor and Council before approval.

Applicants must notify all property owners within one-half mile and all neighborhood associations within two miles for the required neighborhood meeting and public hearing.

A facility is regulated as a large-scale data center if it has more than 25,000 square feet of gross floor area or uses more than 20 megawatts of energy, including multiple facilities or portions of facilities on a contiguous site under the same controlling ownership.

Large-scale data centers must be at least 2,640 feet from residential zones and specified sensitive uses, including nursing homes, residential-care facilities, and educational uses.

Large-scale data centers must be at least 1,000 feet from commercial or office zones.

Large-scale data centers are subject to a maximum height of 50 feet.

Applicants must demonstrate access to an adequate water supply and comply with the City's Large Quantity Water User Ordinance when applicable.

Users expected to consume at least 10,000 hundred cubic feet of water per month, approximately 7.48 million gallons, must obtain approval through a sustainable water service application and water conservation plan before receiving new or expanded water service.

Large water users must remain within approved water-use limits, maintain required conservation or reclaimed-water measures, and update their conservation plans every five years.

If the Large Quantity Water User Ordinance does not apply, potable water may not be used for data-center cooling; the applicant must demonstrate adequate water supply and may be required to submit a mitigation plan for drought or local water emergencies.

Applicants must demonstrate adequate energy supply and disclose the proposed energy amount and energy mix, including renewable sources.

Applicants must submit an independent noise study and noise-mitigation plan, comply with decibel limits at the property line, and conduct annual noise monitoring.

Generators and other noise-producing mechanical equipment must use solid screening walls or rooftop screening to block sound.

Backup generators are limited to Tier IV or natural-gas/dual-fuel generators, must use battery-first backup systems, are subject to limits on maintenance-testing hours, and may not be used for load shifting.

The City may require data-center operators to designate a point of contact for community concerns about noise or other negative impacts.

Projects must provide a 40-foot enhanced landscaping border and meet additional environmental and plant-salvage requirements.

Lot coverage is limited to 40%; the remaining area must be dedicated to natural open space, and disturbed land outside the project site must be revegetated with native plantings.

Large-scale data centers must comply with applicable Native Plant Preservation, Commercial Rainwater Harvesting, Environmental Resource Zone, and Watercourse Amenities, Safety, and Habitat requirements.

The Mayor and Council may require protection of sensitive lands off-site at a two-to-one ratio as part of approval.

Facilities with no more than 25,000 square feet and no more than 20 megawatts of energy use are outside the definition of a large-scale data center and therefore avoid the measure’s large-scale-specific approval and operating requirements. The thresholds apply on an either/or basis: exceeding either threshold qualifies a facility as large-scale. minimum floor area of 25,000 square feet, or power consumption of 20 Megawatts

The regulations provide parking flexibility by allowing parking standards to be right-sized for the facility, reducing unnecessary paved parking areas. The facility must still comply with the applicable Unified Development Code requirements. right-size parking standards to reduce paved surfaces

A project may, at the discretion of the Mayor and Council, protect sensitive lands off-site instead of providing all required protection on the development site. The off-site protection must be provided at a 2-to-1 ratio. protect sensitive lands off-site at a 2:1 ratio
