Data centers are permitted by right only in the Light Industrial (LI) and Heavy Industrial (HI) districts; they are not listed as permitted in the other districts. The ordinance states that a use not listed or similar to a listed use is prohibited. Data Centers are listed only in LI and HI

The floodplain overlay limits uses to those also permitted in the overlay

In a water-supply overlay, storage of toxic or hazardous materials is excluded unless a spill-containment plan is implemented. Development is also subject to built-upon-area limits of 24 percent in the watershed balance and 12 percent in critical areas, plus minimum vegetative buffers of 30 feet, or 100 feet when using the 70-percent built-upon-area option. Nonresidential development exclusions and spill-containment requirement

New development is generally prohibited within the water-supply overlay buffer, except for water-dependent structures and certain public projects where no practical alternative exists. No new development is allowed in the buffer

A data center within an airport overlay must comply with site-specific height limits for structures and trees, may not create specified aviation hazards, and requires a permit before a material change of land use or before erecting, altering, planting, or establishing a structure or tree in a protected airport surface.

The use remains subject to the district’s other applicable requirements and conditions. (Data Centers)
