Data centers are permitted by right in the Technology Overlay District except in TOD West, where a conditional use permit is required.

Data centers outside the TOD would be prohibited under the proposed 2026 amendments; the restriction is proposed and was not yet final in the source.

Data centers must use public water and sewer systems. On-site water reuse or wastewater pretreatment is allowed, but private wells and independent wastewater systems are not authorized by the TOD standard.

For TOD campuses adjacent to residentially zoned property or residential mixed-use development, noise measured at the property line may not exceed 55 dBA and 65 dBC.

Applicants must submit a qualified third-party environmental noise assessment with the initial plan of development, provide a peak-operating assessment within three months after operations begin, and provide additional studies when requested by the zoning administrator, with no more than four requested studies per calendar year.

Generators may operate only for testing or emergencies. Testing is limited to two hours per day between 10:00 a.m. and 5:00 p.m. Monday through Friday, unless a state or federal air-quality agency requires otherwise.

Generator testing schedules must be posted annually on a dedicated company webpage, with at least 48 hours' notice of schedule changes.

Generators near residential property must be shielded and screened through specified measures, including enclosure, opaque walls or approved enclosures, terrain or berms that substantially eliminate ground-level visibility, and low-emission Tier 4 diesel generators, unless equivalent newer methods are approved.

The maximum structure height is 120 feet, and structures over 60 feet require an approved fire-sprinkler system and specified setbacks. Structures over 80 feet may not be adjacent to residential property, residential mixed-use development, or certain non-TOD A-2 property, although a conditional use permit may exceed the height restrictions.

On M-1 or M-2 property, a data center and its exterior mechanical equipment, including generators, must be at least 300 feet from residentially zoned property or residential mixed-use development.

On property other than M-1 or M-2, a data center and its exterior mechanical equipment must be at least 500 feet from residentially zoned property or residential mixed-use development; a conditional use permit may reduce that distance to 300 feet.

Data centers adjacent to property not zoned M-1 or M-2 must provide a minimum 250-foot vegetated buffer.

Access to a TOD-permitted use generally may not connect to local roads within residentially zoned areas, except when the access is solely necessary for emergency service vehicles.

Exterior construction activity next to residential property or residential mixed-use development is limited to 7:00 a.m. through 7:00 p.m., Monday through Friday, subject to limited emergency or unusual-circumstance exceptions.

Each technology campus outside a planned development park must obtain approval of a conceptual master plan before any building permit or plan of development may be approved for campus parcels, structures, or infrastructure.

A conceptual master plan must provide at least 20 percent open space.

Conceptual master plans generally require perimeter buffers, including 200 feet next to residential or agricultural property, 150 feet next to arterial roads, and 100 feet next to collector or local roads.

Conceptual master plans generally require setbacks that prohibit permitted uses, refuse storage, or loading areas within 200 feet of residential or agricultural property, with additional road and neighboring commercial or industrial property setbacks.

Buildings visible from roads outside the campus or from residential property must meet principal-façade design standards, including at least two specified elements such as varied height or rooflines, step-backs or recesses, substantial fenestration, or changes in materials, patterns, textures, or colors.

Outdoor storage, loading areas, refuse areas, treatment plants, utility facilities, truck and trailer parking, and accessory equipment must be screened from public roads and residential or agricultural property; a viewshed analysis is required with the plan of development.

Under the proposed 2026 amendments, a facility drawing 100 megawatts or more would require a state-required site assessment before county approval, addressing at least noise impacts on homes and schools and generator air quality, with the county also requiring review of specified agricultural, water, park, open-space, and historic-resource impacts.

The proposed 2026 amendments would subject the TOD to a second public process, including a community meeting, Planning Commission review and recommendation, and a Board of Supervisors public hearing and final vote before re-adoption; the source states that the language was not yet final.

Data centers are permitted by right throughout the Technology Overlay District, except in TOD West, where a conditional use permit is required. Data centers are permitted by right

The ordinance reduces the standard parking requirement for data centers to one space per 400 square feet of office space plus one space per 4,000 square feet of other space, or an alternative amount authorized through plan-of-development approval based on an operational parking study. one space per 400 square feet of office space

A conceptual master plan is reviewed and approved administratively by the zoning administrator, rather than requiring approval through a separate legislative process; applicants may appeal a decision to the Planning Commission within 15 days. subject to administrative review and approval by the zoning administrator

The plan-of-development process may grant exceptions to TOD design standards when County staff finds that the TOD's purpose, intent, and aesthetics will be met and the proposal substantially complies with the approved conceptual master plan. exceptions to the TOD design standards

A conditional use permit may authorize structures to exceed the stated TOD height restrictions. The ordinary maximum structure height is 120 feet, with additional exemptions for specified rooftop equipment and no height limit for certain utility infrastructure. A conditional use permit can be granted to exceed these height restrictions

For data centers outside M-1 or M-2 zoning, the required 500-foot distance from residential or residential mixed-use property may be reduced to 300 feet through a conditional use permit. the distance can be reduced to 300 feet through a conditional use permit

Certain supporting facilities are authorized as accessory uses for TOD technology uses, including water and sewage treatment, central heating or cooling, structured parking, general offices, storage and maintenance facilities, and qualifying accessory energy storage. accessory uses, which support the identified permitted uses

Accessory onsite energy-generating facilities, other than solar facilities, and emergency generators may be used with a conditional use permit; supplementary solar facilities and qualifying energy-storage facilities are also authorized as accessory uses. Energy generating facility for onsite consumption

The comprehensive plan treats installation or extension of public roads, public facilities, and public utility facilities within the TOD as substantially consistent with the plan, supporting infrastructure needed by technology campuses. the installation or extension of public roads, public facilities, and public utility facilities

Parking, transmission substations, stormwater facilities, and sound-attenuation improvements may be located within the data-center setback, provided they remain at least 10 feet from the required buffer, giving developers additional flexibility in arranging the site. Improvements such as parking, transmission substation, stormwater management

Generators may operate during emergencies and for limited testing, allowing data centers to maintain backup power subject to the ordinance's testing hours, notice, screening, and emissions-related conditions. Generators cannot be operated other than for testing and during emergencies
