Yavapai County requires a Grading Permit (PB-22) for cuts/fills exceeding thresholds in the Planning and Zoning Ordinance. Sites must implement erosion and sediment controls meeting the AZPDES General Construction Permit. Buildings in erosion-hazard areas need foundations three or more feet below projected scour depth.
The PB-22 Grading Submittals checklist, revised January 2026, governs grading permits in unincorporated Yavapai County. A Grading Permit is required for cuts or fills exceeding the volume and depth thresholds in the Planning and Zoning Ordinance, and for any work in a FEMA floodplain. Submittals must include a grading plan signed by a registered engineer, a SWPPP if disturbance reaches one acre, and erosion BMPs - silt fence, fiber rolls, sediment basins, stabilized entrances. Under Ordinance 2010-1, foundations in erosion-hazard areas adjacent to washes must extend at least three feet below the calculated 100-year scour depth. The Drainage Design Manual provides hydrologic methods. The Code Enforcement Unit responds to complaints about uncontrolled grading and runoff.
Stop-work orders, daily civil penalties under the grading ordinance, and ADEQ AZPDES fines up to $25,000 per day for sediment discharges. Restoration of unauthorized grading at owner expense.
