Retains a conditional pathway through special land use permits in industrial districts.

Data centers are classified as special land uses in I-1 Light Industrial and I-2 General Industrial districts, requiring special land use approval rather than ordinary permitted-use approval.

A principal-use data center must comply with the ordinance's data-center standards and all other applicable zoning-code development standards.

A data center qualifies as an accessory use exempt from the data-center section only if it exclusively serves the on-site owner or tenant, does not provide services to off-site parties, occupies no more than 10% of the building footprint, and is not in a separate standalone building.

Data-center applications require zoning administrator review and recommendation followed by Planning Commission review under the special-land-use procedures; officials generally may not waive zoning-code requirements.

Applicants must submit a project narrative, operational plan, good-neighbor policy, water-consumption and thermal-management report, wastewater report, electric and natural-gas service report, initial sound study, tree-preservation and reforestation plan, waste-disposal and decommissioning plan, heat-mitigation plan, and emergency-management plan.

The water report must provide detailed projected annual, monthly, typical-day, peak-day, and instantaneous water demand, meter information, high-demand operating flexibility, and water-conservation measures.

The wastewater report must document discharge methods, expected daily discharge, treatment systems, monitoring equipment, pipe specifications, flow direction, and required permits and analyses.

The applicant must submit a third-party initial sound study measuring baseline levels at the site and at the property line of the nearest residential district, residential use, or other sensitive use.

The applicant must hold at least two neighborhood meetings, provide mailed notice to affected owners and homeowners' associations within a half-mile, post on-site and newspaper notices, and maintain an online project website with application materials; notices generally must be provided at least 15 days in advance.

A data center and its associated mechanical equipment must be at least 500 feet from the property line of the nearest residential zoning district, residential use, or other sensitive use. The Planning Commission may waive this setback for solar facilities developed with the data center, subject to the separate solar-facility requirements.

The facility must incorporate sound mitigation based on the initial study so that emissions do not exceed the measured ambient levels at the nearest residential or sensitive property line, and noise may not exceed 55 decibels there; violations are public nuisances.

Sound-mitigation design specifications must be submitted to and incorporated into the building design before building-permit approval.

The data center must pay the full cost of undergrounding adjacent or on-site electrical infrastructure that the City determines is necessary and the utility approves.

Within 30 days after the first certificate of occupancy or completion, the operator must obtain a third-party sound study during peak routine mechanical operation.

The operator must obtain annual third-party sound studies during peak routine mechanical operation for five years after the initial post-construction study and submit the results with required business-license renewal.

If public water-system conveyance or capacity must be increased for the data center, the data center must bear the cost.

If public wastewater-system conveyance or capacity must be increased for the data center, the data center must bear the cost.

The decommissioning plan must address removal and disposal of infrastructure, hazardous materials, batteries, electronic waste, wastewater systems, and chemical waste, and must provide a surety bond or cash deposit to fund site decommissioning and stabilization.

Backup-generator operation requires a public website, at least 72 hours' advance notice for routine operation or testing, and operation only between 9:00 a.m. and 5:00 p.m. Monday through Friday excluding holidays, unless generators support an outage or utility demand-response event.

The operator must pay all interconnection costs associated with operating a generating system.

The operator must submit annual water, wastewater, and sound-study compliance reports as required, and a business license subject to renewal may not be issued until those reports are submitted; failure to obtain the license may result in penalties.

Data centers are added as special land uses in both I-1 Light Industrial and I-2 General Industrial districts, allowing them to be proposed in those districts subject to special-land-use review and applicable development standards.

An on-site data center may qualify as an accessory use and avoid the ordinance’s data-center-specific requirements if it exclusively serves the on-site owner or tenant, does not provide services to off-site parties, occupies no more than 10% of the building footprint, and is not in a separate standalone building.

The Planning Commission may waive the 500-foot separation requirement for solar power facilities developed together with a data center, although those solar facilities must still comply with the City’s separate solar-power-facility requirements.

Data centers are classified as special land uses in the I-1 Light Industrial and I-2 General Industrial districts, rather than as permitted uses. Added to the list of Special Land Uses

Data centers are added as special land uses under both I-1 Light Industrial and I-2 General Industrial zoning, creating an expressly recognized path for approval in those industrial districts through the special-land-use process.

A data center may be treated as an accessory use and avoid the ordinance’s data-center-specific requirements if it exclusively serves the on-site owner or tenant, does not provide storage or processing services to off-site parties, occupies no more than 10% of the building footprint, and is not in a separate standalone building.

The Planning Commission may waive the 500-foot separation requirement for solar power facilities developed in concert with a data center, although those solar facilities must still comply with the applicable solar-facility requirements.

The ordinance expressly contemplates backup generators for data centers, allowing them to operate during power outages or electric-utility demand-response events without the ordinance’s normal operating-hour limit; routine operation and testing otherwise require 72 hours’ advance website notice and are generally limited to 9:00 a.m. to 5:00 p.m., Monday through Friday, excluding holidays.
