Data centers require conditional-use authorization under the amended zoning framework.

The framework adds operational and infrastructure assurances for data centers; the provided source does not specify their terms.

The amendment establishes data centers as a defined land use and allows them to seek zoning approval through a conditional-use process, subject to the measure’s requirements; it does not describe the specific approval criteria. conditional-use authorization

Data centers may be located only in the I-1 or I-2 Heavy Industrial District, and only with an approved Conditional Use Permit (CUP). authorized only as a conditional use

A CUP is required before establishing, constructing, expanding, materially modifying, or operating a data center. Approved plans, studies, mitigation measures, agreements, and permit conditions remain ongoing requirements; deviations can lead to enforcement, stop-work orders, or CUP suspension or revocation. No data center shall be established

Data centers must be in permanent buildings or permanent accessory structures; they cannot operate in shipping containers, portable units, trailers, temporary structures, or similar movable enclosures. permanent principal building

A smaller ancillary computing facility may avoid the data-center CUP only if it serves the same lot’s lawful principal use internally, provides no services to third parties, and occupies no more than 10% of the principal building’s gross floor area; otherwise, the CUP process applies. does not exceed ten percent

CUP applicants must submit detailed site plans and a project narrative covering development phases, construction and generator-testing hours, employees, truck traffic, security, cooling, backup power, utility demands, water use, wastewater, and mitigation. They must also provide utility-demand information and, if the City reasonably requires it, additional studies or an informational neighborhood meeting. every application for a Conditional Use Permit

Before CUP approval and before a grading or building permit, applicants must fund a City-selected independent professional’s review or preparation of a preconstruction sound study. Data-center sound is capped at 60 dBA at property lines adjoining residentially zoned or used property and 65 dBA at property lines adjoining commercially or industrially zoned property. The City may require further testing or monitoring at the operator’s expense and require mitigation. sixty (60) dBA

Routine backup-generator testing must be coordinated with the City and limited to weekday business hours, except during emergencies, utility interruptions, or circumstances beyond the operator’s reasonable control. The City may also restrict test timing, duration, frequency, sound attenuation, and screening. limited to weekday business hours

Exterior lighting must minimize glare, sky glow, and light trespass. Unless the City approves otherwise upon a showing of necessity, maintained vertical illumination at a residential property line may not exceed 0.5 footcandles. shall not exceed 0.5 footcandles

Water-based cooling must use closed-loop systems; once-through cooling is prohibited. Applicants must provide a water-use and wastewater-management report, and construction or operation cannot begin unless the City finds sufficient water and sewer capacity without impairing existing customers or requiring public spending unless the City Council expressly approves it. Once-through cooling systems shall be prohibited

The developer or operator must pay for water, sewer, cooling-related, wastewater, and other infrastructure improvements needed to serve the facility or mitigate its impacts. Before a building permit, the applicant must enter City-approved agreements providing payment or financial assurances, which may include escrow, bonding, or a letter of credit. solely responsible for all costs

Before CUP approval and before a grading or building permit, the applicant must fund a City-selected engineer’s roadway and transportation impact analysis. The developer or operator must pay for required road, traffic-control, pavement, drainage, and other transportation mitigation, and the City may require bonding, escrow, a development agreement, or other security. roadway and transportation impact analysis

Each site must have security fencing and controlled access. Unless the City specifically approves otherwise through the CUP process, perimeter fencing must be at least 8 feet high and made of durable commercial-grade materials; applicants must also submit a security plan, and the City may require visual screening. at least eight (8) feet in height

Expansion, intensification, or material modification requires prior City review and approval and, when required by the City, a CUP amendment. Material changes include added generators, cooling systems, or substations; a change in cooling technology; material increases in water, sewer, traffic, electrical demand, or sound; and substantial access, circulation, loading, or security changes. prior review and approval by the City

Owners and operators must allow the City and its consultants reasonable access, on reasonable notice and in accordance with law, to inspect improvements and verify compliance or conduct authorized monitoring and testing. permit the City and its consultants reasonable access

Data centers are authorized as conditional uses in the I-1 Industrial and I-2 Heavy Industrial districts, subject to a Conditional Use Permit and compliance with the ordinance and other applicable code requirements (authorized only as a conditional use).

A facility serving only the internal needs of a lawful principal use on the same lot may include ancillary computing facilities as an accessory use without separate conditional-use approval, provided it does not serve third parties and does not exceed 10% of the principal building’s gross floor area; the City may approve a larger share through the conditional-use process (may be permitted as an accessory use).
