The Mississippi River and Apple Creek bottoms drive flood-zone questions

Perry County’s eastern boundary is the Mississippi River, and the river bottoms along with the Apple Creek drainage put parts of the county in mapped floodplain. For anyone buying, building, or insuring property on low ground near the river or the creek, the practical step is to check a specific parcel’s flood-zone designation at the FEMA Flood Map Service Center rather than assuming a property is high and dry. Flood-zone status affects insurance requirements and what can be built where. Missouri’s Department of Natural Resources provides state floodplain-management context, and county emergency management is the local anchor for past events and current rules. Avoid relying on current river-stage readings, which change constantly; the durable question is where a parcel sits relative to the mapped floodplain. Levee or drainage districts may exist in the bottoms and are worth confirming for any specific tract.
