Data processing centers are prohibited outside properties zoned Major Industrial Development (MID) or Regional Area Industrial (RAI). The county says they may be located only in MID or RAI areas.

In RAI zones, a data processing center requires administrative review; in MID zones, the use is listed as permitted. The land-use table lists data processing centers as administrative review in RAI and permitted in MID.

Data-center equipment must be enclosed in buildings with sound-absorbing materials; vibration isolation is required where a center is in a multi-tenant building. An acoustic barrier or wall at least eight feet high must be built along exterior property boundaries, set back ten feet from adjoining property lines, with an exception within ten feet of a driveway; at least one shrub per ten feet of barrier must be planted outside it. These noise and vibration standards apply to data processing centers.

Mirrored glass and polished metal are prohibited. The main entrance must be visually differentiated from the building facade and project or recess at least five feet from the adjoining building plane. Exterior lighting must comply with the county’s lighting standards. The data-processing-center standards set these requirements.

Data processing centers are allowed in Major Industrial Development (MID) zones and may be approved by administrative review in Regional Area Industrial (RAI) zones; they are not allowed in other zones. MID and RAI locations

In an MID, a major industrial project can use a Type III binding site plan process before the hearing examiner; final master-plan approval authorizes applications for building permits, subject to the approval’s terms and conditions. Building permits after final approval

MID development may provide needed infrastructure and services—including utilities, water, sewer, stormwater, fire suppression, and transportation—or arrange for outside providers to supply them through shared-services agreements. The development must cover costs attributable to it, and the facilities generally cannot serve property outside the MID. Shared-service infrastructure

Energy production and storage facilities are permitted in the MID, creating a route for energy facilities to be developed in the same zone as data centers. Energy facilities in the MID

An approved MID binding site plan may be amended within the original site-plan boundaries through a binding-site-plan amendment decided by the hearing examiner. This allows changes within the approved site area, but does not itself expand the MID zoning boundary. Amendments within the site-plan boundaries
