Boone County checks building permits against flood maps
The county floodplain page says building permit applications are checked against flood maps, which matters for Missouri River bottoms and low ground.
Boone County’s river and creek bottoms make floodplain status a real parcel question. Building permit applications are checked against flood maps to see where a proposed structure sits relative to the regulatory floodplain.
That does not mean every low-looking field is unbuildable, and it does not mean every Boone County property has the same flood risk. It means the map layer matters before construction.
For land near the Missouri River bottoms, Perche Creek, Hinkson Creek, or other low ground, check the FEMA map and the county Resource Management page before assuming where a house, shop, or addition can go.
Floodplain review is better handled early, while a buyer can still ask questions and a builder can still change the plan.
