Platte County has a flood development permit path

Platte County’s river and creek bottoms make floodplain paperwork more than a map lookup. The county’s Flood Development Permit application asks whether the property is in a designated floodway or floodway fringe and what kind of development is proposed, including filling, grading, excavation, maintenance, improvement, or new construction.

The form also asks whether other permits may be required, including Corps of Engineers, state, local levee district, or local drainage district permits. That is the local clue: floodplain work may involve more than one government layer.

Before changing ground, improving a structure, or buying a low-lying parcel, check the FEMA map and Platte County Planning and Zoning. A permit question answered early is cheaper than discovering it after plans are drawn.
