Data centers may be built only on land zoned Technology Campus (TC). “only zoning classification where data centers”

Hyperscale data centers—those designed for a total electrical load greater than 50 MW or a campus of at least 500,000 square feet—must use a planned development in the TC district and follow the planned-development procedure. “greater than 50 megawatts”

TC sites bordering residential districts must provide an 8-foot earthen berm or mound with additional landscaping, plus a landscaped buffer at least 25 feet wide and specified tree-planting and screening measures. “minimum of eight feet in height”

Noise from site operations may not exceed 65 dB at the property boundary; emergency generators are exempt during brief testing, maintenance, or emergency operation. “shall not exceed 65 decibels”

Air emissions must comply with applicable IDEM and EPA standards, and windborne dust and other air pollution must be kept to a minimum. “shall not violate the standards and regulations”

Odors or odor-causing substances may not be detectable without instruments at or beyond property boundaries. “no emission of odors”

Water used to cool industrial processes must use a closed-loop system that recirculates water rather than taking in new water and discharging it after use. “must utilize a closed-loop system”

The ordinance establishes a Technology Campus district and makes it the only zoning classification where data centers may be built. Hyperscale data centers—over 50 MW of electrical load or at least 500,000 square feet—must use the planned-development process within TC. TC is the only zoning classification where data centers may be constructed.

The ordinance expressly permits utility infrastructure, including substations and distribution facilities, as well as renewable energy generation and storage in the TC district. Utility infrastructure facilities including electrical substations.

It permits operational support uses and equipment, including emergency generators and backup power, cooling towers and chillers, fuel storage for emergency generators, and related utility and telecommunications equipment. Emergency generators and backup power systems.
