Accessory solar development used to power a data center must comply with the Solar Energy Systems application requirements and review standards in Article 6, which can require a separate solar permit and administrative, Planning Commission, or Board review depending on the solar system's size. Accessory solar development to power the Data Center shall meet the application requirements and review standards

If accessory solar is required for a data center, the solar application must include applicable fees, and the applicant—not the County—must pay consultant and referral-agency review costs. The costs of consultant and referral agency reviews are the responsibility of the applicant

Data centers are expressly recognized as a permitted development category in the West End (WE) Zone District, although they remain subject to the County’s development-permit requirements under Section 5-320 J. WE-zone data-center exception

A data center may include accessory solar development to supply its power, provided that the solar facilities comply with the application requirements and review standards in Article 6, Section 6-2. Accessory solar development to power the Data Center

Data centers in the West End Zone District require a two-step Special Use Permit review by the Planning Commission and Board of County Commissioners before development or operation.

Data centers in the West End Zone District require a development permit and a building permit, even though most development in that district is exempt from those permits.

No more than three data centers may be permitted in the West End Zone District.

A data center must be located on a parcel of at least 35 acres, set back at least 50 feet from property lines, and at least 500 feet from residences.

A data center must be located within the Egnar-Slickrock or Norwood Fire Protection District.

Sound emissions must be less than 50 decibels at every property line, supported by a sound and vibration impact analysis with an ambient-noise baseline and mitigation measures.

All data-center equipment, including cooling and ventilation equipment, transformers, and generators, must be fully screened unless site topography effectively screens it.

Data-center facilities and operational components must be located within buildings; cargo containers, railroad cars, semi-truck trailers, and similar containers may not be used.

Expired or unused electronics or equipment may not be stored on the data-center site.

A data center must be designed as a net-zero facility with on-site renewable energy sufficient to approximately offset grid energy use, add renewable energy to the grid, and avoid burdening the local or regional electrical grid.

Applications must include all substations and infrastructure upgrades needed for construction and operation and demonstrate adequate supply-line and substation capacity without electrical interference or voltage fluctuations.

All power lines serving or associated with a data center must be installed underground.

Except for water used by on-site workers during work shifts or workers living on the property, a data center must use water non-consumptively, have no effect on area water resources, and may not use water to cool equipment.

Accessory solar development used to power a data center must satisfy the County's Article 6, Section 6-2 application requirements, review standards, and applicable solar permit requirements.

Applications must include a fire-suppression plan addressing major fire hazards, hazardous materials, ignition sources, controls, and required fire-protection equipment.

Applications must include a Wildfire Mitigation Plan addressing wildfire prevention, fuel reduction, fire suppression, fire safety, and measures preventing facility fires from spreading.

The data center and related infrastructure must mitigate impacts on wildlife, plants, and other natural resources, supported by wildlife-impact and natural-resources reports prepared by qualified biologists.

Special Use Permit applications must include detailed site, building, operations, traffic, parking, grading, drainage, water, sewer, lighting, dust-control, noxious-weed-control, wildlife, and other required agency-permit materials.

Because data centers are special uses, the County may require a bond sufficient to cover site remediation and compliance with permit conditions.

Approved special uses are subject to an annual review one year after approval or amendment, and the reviewing body may require additional ongoing or periodic reviews.

A special use must commence within three years after approval; otherwise, it is subject to a noticed public-hearing review and may be modified, extended, or rescinded.

If an approved special use is discontinued or abandoned for 12 consecutive months, it becomes ineffective and must undergo review before it can be re-established.

Construction or development in a Special Flood Hazard Area requires a Floodplain Development Permit before work begins, in addition to other required permits.

Uses not listed as allowed or prohibited in a Floodway, Flood Fringe, or Flood Prone District require Special Review rather than administrative approval.

Development in a regulatory Floodway is prohibited unless a Colorado-licensed professional engineer demonstrates through hydrologic and hydraulic analysis that it will not increase flood levels; projects that would increase elevations require a FEMA CLOMR and floodway revision before proceeding.

New construction and substantial improvements to nonresidential structures in mapped flood hazard areas must elevate the lowest floor and utilities at least one foot above base flood elevation or use certified watertight construction capable of resisting flood forces.

If classified as a Critical Facility, a data center generally must be outside the Special Flood Hazard Area or be elevated or floodproofed at least two feet above base flood elevation; new Critical Facilities must also have continuous non-inundated emergency access during a 100-year flood when practicable.

For proposals involving Special Review or disputed hazardous conditions, the County may require a professional-engineer-certified floodplain study covering the site and 200 yards upstream and downstream.

The West End Zone permits up to three data centers, subject to applicable development and Special Use Permit standards.

A parcel in the West End Zone may contain two principal uses, allowing a data center to coexist with another principal use if applicable requirements are met.

A data-center application may include substations and electrical-infrastructure upgrades needed for construction and operation, provided adequate electrical capacity is demonstrated and Code requirements are met.

Data centers may generate on-site renewable energy through solar or wind facilities to support required net-zero design and offset grid energy use.

Data centers may operate with non-consumptive water use, provided water is not used to cool equipment; water for on-site workers and workers living on the property is excepted.

Data centers may be located in either the Egnar-Slickrock Fire Protection District or the Norwood Fire Protection District, subject to applicable fire-suppression and wildfire-mitigation requirements.

In the WM Zone District, data-center development generally does not require a development permit because the listed exceptions do not include data centers, although other permits, including any required building permit, may still apply.
