Clay County floodplain work needs its own permit
In unincorporated Clay County, floodplain development is a separate permit check before construction, grading, filling, or similar work begins.
A floodplain question in unincorporated Clay County is a permit question, not only a map lookup.
In unincorporated Clay County, mapped A, AE, AO, and AH zones have a separate permit path. Development cannot begin there until a Floodplain Development Permit is issued.
The word “development” is broader than a new house. It can include buildings, levees, dredging, filling, grading, paving, excavation, drilling, and storing equipment or materials. If the same project also needs a building permit, the floodplain permit comes first.
The jurisdiction line matters too. Clay County Planning and Zoning covers unincorporated areas. If the property is inside Liberty, Smithville, Kansas City, or another incorporated city, start with that city. For creek bottoms, river bottoms, or mapped flood zones outside city limits, check the floodplain permit path before pricing the work.
