Planners propose a definition for data centers; members raise infrastructure concerns

Planning staff proposed adding a definition for "data centers" to the city zoning code to provide a clear basis for later permitting or special‑use decisions.

Staff’s suggested definition described data centers as establishments that engage in the storage, management, processing and transmission of digital data and house computer and network equipment, servers, and related components. Staff said the language was adapted from other jurisdictions and is intended to allow the city to regulate — later — whether data centers would be allowed as permitted uses, special uses or prohibited uses in particular zoning designations.

Several board members expressed concern about the utilities data centers require. One member, drawing on personal experience, said data centers "require an enormous, enormous amount of electricity" and suggested the city should demand a study from CPS regarding electrical capacity before allowing such uses nearby. Another member observed that CPS is preparing to support incoming data‑center demand in some parts of the region.

Board members and staff agreed to keep this agenda item limited to adopting a definition; regulatory and permitting concerns (including utilities studies, water use and possible special‑use conditions) were left for future action. Staff will include the definition in upcoming code‑revision materials and bring any permitting recommendations later if interest develops.
