Data Center Zoning & Siting
Washington County confines any data, AI, or crypto center to its Industrial (IND) zone, never the adjoining Manufacturing (MFG) zone, and hard-caps every facility at 10 to 50 megawatts; the code states plainly that larger capacity facilities are not permitted. A qualifying site needs a 5-acre minimum lot, and the IND zone itself cannot sit next to any residential, forest residential, agricultural, estate, or open-space zone.
