Missouri has no statewide grading permit. Earthwork disturbing one acre or more triggers a state land disturbance permit, and unincorporated Clay County reviews grading and drainage under its Land Development Code.
Grading in Clay County is governed by state stormwater rules and local review rather than a single grading permit. Any earth-moving that disturbs one acre or more must register for a Missouri land disturbance permit and control runoff. In unincorporated areas, the Planning and Zoning Department reviews grading and drainage through the Land Development Code and subdivision process, requiring that site drainage not divert concentrated runoff onto neighboring tracts. Cities apply their own grading codes and often Kansas City metro APWA standards. Diverting stormwater onto an adjoining owner creates civil liability regardless of the acreage disturbed.
Grading an acre without state permit coverage draws MO DNR penalties and stop-work orders. Diverting concentrated runoff onto a neighbor creates civil liability for drainage damage.
