Data processing, hosting, and related services, a classification that may cover conventional data centers, are prohibited in the I-LF Landfill Industrial District and the OBM-1, OBM-2, TCMU, FC-1, and FC-2 mixed-use districts.

Cryptocurrency data-mining centers are prohibited in the I-MU, I-L, I-LF, and AIM industrial districts and in the OBM-1, OBM-2, TCMU, FC-1, FC-2, FC-3, and U-1S mixed-use districts.

Cryptocurrency data-mining centers require approval as a special permitted use in the I-H industrial district and the U-1R mixed-use district, rather than being allowed by right.

A data-mining center designated as a special permitted use may not operate until the special-permitted-use application is reviewed and approved by the Jefferson Parish Council, with all required conditions satisfied before approval.

Noise, exhaust, heat, and humidity from a data-mining center must not be perceptible at or beyond the property line. A facility within 500 feet of a residential district or use must submit a noise-mitigation plan.

A data-mining center may not create electric or magnetic fields that adversely affect public health, safety, or welfare, including interference with equipment, instruments, or off-site radio, telephone, or television reception.

Cargo containers, railroad cars, semi-truck trailers, and similar storage containers may not be used for any component of a data-mining operation.

Before special-permitted-use approval, the applicant must obtain written verification from the applicable utilities that adequate capacity exists, the infrastructure is properly sized and safe, and the facility will not cause electrical interference or line-voltage fluctuations on or off the premises.

Data processing, hosting, and related services—the classification covering typical data-center operations—are permitted by right in the I-MU, I-L, I-H, and AIM industrial districts, but are prohibited in I-LF. Industrial use matrix

Data processing, hosting, and related services are permitted by right in the FC-3 Commercial Mixed-Use, U-1S Unrestricted Suburban, and U-1R Unrestricted Rural districts, subject to each district's standards. Mixed-use matrix

A data-mining center using specialized cryptocurrency-mining equipment may locate in the I-H Heavy Industrial District with special permitted-use approval; it is prohibited in the other industrial districts. Data-mining-center matrix

Industrial dimensional standards allow relatively flexible facility design: I-MU has no minimum nonresidential lot area, depth, or width; I-L and I-H require a minimum 5,000-square-foot lot area; and these districts generally have no maximum building height. Height and setback limits still apply near residential zoning. I-MU standards, I-L standards, and I-H standards

Accessory offices and other accessory uses, including restaurants, cafeterias, retail outlets, and wholesale outlets, are allowed in industrial districts when operated with and located on the same site as a permitted industrial use. Authorized accessory uses

Mechanical equipment serving a permitted data center is authorized in industrial districts, subject to the UDC's site-design requirements. Mechanical-equipment provision

Certain changes to an industrial data-center facility are exempt from site-plan review, including interior renovations, routine exterior maintenance, and changes of use that do not increase required parking. Additions below the specified 50-percent threshold generally avoid review in I-MU; in I-L and I-H, the 50-percent rule applies when the district is adjacent to or across a street from a nonindustrial district. I-MU exemptions and I-L exemptions

In the AIM Avondale Industrial Marine District, internal lot lines may be disregarded and parcels may be treated as one development site when tied together by common ownership, a servitude, lease, or similar agreement, facilitating a unified or phased campus. Single-development-site provision

Before a data-mining center is approved, utilities must verify in writing that supply lines and substations have adequate capacity, that utility equipment and electrical infrastructure are properly sized and safe, and that the facility will not cause off-site electrical interference or voltage fluctuations.
