Data centers are expressly permitted only in the M-1 Light Industry and M-2 Heavy Industry districts; because unlisted uses are generally prohibited, locating one elsewhere generally requires rezoning or another applicable approval.

A data center in an M-1 or M-2 district must be on a lot of at least 1 acre with at least 150 feet of lot width, comply with district-specific setbacks, and remain no more than 45 feet tall.

M-1 and M-2 properties abutting residential zoning must provide zoning buffers, generally 75 feet in M-1 and 100 feet in M-2 next to single-family detached residential zoning, with additional requirements for other residential districts.

M-1 industrial operations must be conducted wholly indoors, except for screened outdoor storage in a side or rear yard, limiting outdoor data-center equipment or operational areas.

Data centers must provide parking under the applicable data-center parking standard, ranging from one space per 5,000 square feet to one space per 3,000 square feet, subject to applicable minimum and maximum parking rules.

Non-residential developments with more than 50 parking spaces must provide at least one electric-vehicle charging station for every 50 parking spaces; qualifying redevelopment projects are also covered when repaving or site work affects more than 50 percent of an existing parking area's impervious surface.

Data-center buildings must meet architectural standards governing façade articulation, compatible side and rear materials, equipment screening, permitted materials, and neutral, earth-tone, or natural-finish colors.

Parking-lot and pedestrian-area lighting must use compliant cutoff fixtures, generally LED sources, and meet mounting-height and illumination limits; a site-lighting plan is required in specified circumstances before a development or building permit is issued.

If a data-center proposal requires rezoning, it must receive Planning Commission review and recommendation and undergo public hearings before both the Planning Commission and Board of Commissioners, with specified publication and mailed-notice waiting periods.

A data-center rezoning application must use the public-participation process if it would create more than 5,000 square feet of non-residential building area or disturb more than 10,000 square feet of land; community outreach and a participation report are required no later than 35 calendar days before the Planning Commission hearing.

An addition or renovation increasing a data center's gross floor area by 500 square feet or more requires additional parking and loading space, and a change in use requires parking for the new use.

In the Venture Drive Redevelopment Overlay District, a data center is a special use rather than a permitted use and requires approval of a Special Use Permit, potentially along with supplemental use standards.

In the Venture Drive Redevelopment Overlay District, new construction or renovation exceeding 60 percent of an existing principal structure requires a Special Administrative Permit before demolition, land-disturbance, or building-permit applications; a pre-application meeting and specified review periods also apply.

In the Rowen Innovation Subdistrict, permitted uses are limited primarily to specified research, office, assembly, and high-density mixed-use categories, and development must comply with the Rowen Design Guidelines.

In the Rowen Innovation Subdistrict, an applicant must obtain a Special Administrative Permit before submitting a land-development or building-permit application, including a pre-application meeting and approval documentation from the Rowen Architectural Guidance and Design Review Board.

In the Gateway 85 Overlay District, underlying zoning standards continue to apply in addition to overlay standards, and the more restrictive standard controls; expansions, site disturbance, and changes of use can trigger overlay requirements.

New non-industrial developments exceeding 10 acres in the Gateway 85 Overlay District must provide outdoor Common Area equal to at least 5 percent of net project acreage, generally unavailable for parking or driving and subject to minimum size and contiguity requirements.

A building permit for a data center or other non-residential building cannot be issued until a development permit for the building site has been issued, and the building permit must be consistent with that development permit.

Development permits require approved development plans and approval from affected County departments; applications expire after 12 months without issuance, and issued permits expire if work does not begin within 12 months or is abandoned for more than 60 consecutive days, subject to limited extensions or renewal.

A new building or structure exceeding 100,000 square feet is subject to Special Architectural Design Area review, including color elevations for all sides and an architectural design guide for building and site-accessory elements.

Off-street loading areas are required when goods, merchandise, or equipment are routinely delivered to or shipped from a development; loading spaces cannot be counted as parking, and ordinary loading stalls must be at least 10 feet by 30 feet.

Land-disturbing activity generally requires a land-disturbance permit and an erosion, sedimentation, and pollution-control plan before work begins; phased projects require a separate permit for each phase, with fees charged for each acre or fraction of an acre.

Stormwater treatment or runoff reduction is required for new development creating at least 5,000 square feet of impervious cover, disturbing at least 1 acre, or meeting specified redevelopment or common-plan thresholds; certified stormwater reports and compliant stormwater systems are required.

Projects requiring a development or land-disturbance permit generally must submit a tree-preservation or replacement plan and achieve at least 16 Tree Density Units per acre, or 20 units per acre in specified overlay districts; specimen-tree removal requires approval or may require recompense.

Non-residential developments must install sidewalks on new internal streets and along abutting external streets before receiving a Certificate of Occupancy, and multi-use paths may be required along arterial streets or designated trail corridors.

Multifamily and non-residential developments abutting a County road must provide required access improvements, such as deceleration and left-turn lanes; the developer must fund associated right-of-way and drainage improvements.

In the Gateway 85 Overlay District, new utility lines must be buried and streetlights provided; on Priority Corridors, driveways generally cannot be located on the corridor when access is available from a non-Priority-Corridor right-of-way.

Buildings and structures generally cannot be located within a future-conditions floodplain, and development affecting a floodplain must satisfy floodplain plans, engineering, elevation, no-rise, flood-storage, drainage, and utility-protection requirements.

Development near streams must maintain a 50-foot undisturbed stream buffer plus an additional 25-foot impervious-surface setback; activity in the buffer or impervious cover in the setback is prohibited unless a variance is granted.

Data centers are expressly permitted in the M-1 Light Industry and M-2 Heavy Industry districts without a Special Use Permit, provided all other requirements are met. Data Center P P

The M-1 and M-2 districts provide industrial development standards for data centers, including a minimum one-acre lot, maximum FARs of 1.0 in M-1 and 2.0 in M-2, and a maximum building height of 45 feet. Dimensional Standards

In the M-1 and M-2 districts, data centers require at least one parking space per 5,000 square feet and are subject to a maximum of one space per 3,000 square feet. Data Center

Data centers may be approved as a special use in the Venture Drive Redevelopment Overlay District through a Special Use Permit, subject to any applicable supplemental use standards. The measure lists “Data Center” as a special use

Property owners may elect to redevelop under the Venture Drive Redevelopment Overlay while retaining the underlying zoning until the election, preserving the option to use the existing zoning.

The Venture Drive Redevelopment Overlay permits a maximum FAR of 5.0, calculated on gross land area before land is taken for proposed streets or pedestrian ways, and allows floor area to be distributed across blocks in multi-block projects.

The overlay provides flexibility in meeting open-space requirements by allowing sidewalk clear zones, supplemental zones, pedestrian-way public zones, and amenitized stormwater areas to count; open space may be distributed across blocks or aggregated, and the Director may reduce the requirement for an initial phase when strict compliance is infeasible.

For new construction or renovations exceeding 60 percent of an existing principal structure, the overlay provides a Special Administrative Permit process with a pre-application meeting within 14 days, an initial response within four weeks, and issuance within 30 days after a compliant resubmittal.

The Director of Planning may grant variations from overlay standards for hardship caused by extreme topographical or site conditions, or for an alternative solution that meets or exceeds the ordinance's standards; variations are unavailable for uses not listed in the ordinance.

In the Venture Drive Redevelopment Overlay, data centers have a specific parking classification requiring at least one space per 500 square feet and allowing up to one space per 200 square feet. Data Center parking classification

Up to 15 percent of required parking spaces may be compact spaces, provided each is 8.5 feet wide by 16.5 feet deep and clearly marked. Compact spaces

Required parking may be provided off-site within 500 feet of the main entrance when it cannot reasonably be provided on the data-center lot, if the applicant documents that the spaces will be permanently available. Off-site parking

Qualifying on-street parking may count toward the minimum parking requirement at a ratio of 0.5 required spaces for each on-street space. On-street parking

The Director may reduce required parking by up to 10 percent through an administrative variance when the applicant provides written justification based on site hardship, environmental sensitivity, or excessive parking demand. Parking reduction

Parcels whose off-street parking is entirely in a parking structure are not subject to the maximum parking limit. Structured parking

Lawful nonconforming data-center uses may continue, but generally may not expand into a larger land or building area, be reestablished after 12 months of discontinuance, or change to another nonconforming use. May be continued

Lawfully existing nonconforming buildings and site features may generally be retained, although enlargement or changes that increase nonconformity are restricted and rebuilding after qualifying disaster damage must conform to the UDO. May be retained

Lawfully issued permits and qualifying pending or accepted permit applications, subdivision plans, and final plats may proceed under their prior approvals despite later amendments, provided the approval remains valid, construction begins within the required period, and the work follows the approval. Prior approvals

Previously granted variances, zoning map amendments, Special Use Permits, and their conditions remain enforceable after later UDO amendments as long as their terms and conditions are followed. Shall continue to be enforced
