Flood Zones in Reno County, KS: Maps & Permits

Reno County's flood-zone picture is genuinely in flux, not static. The county's current effective FEMA floodplain maps exist alongside a newer set of draft floodplain maps already in circulation, and the Arkansas River runs directly through Hutchinson -- meaning a parcel's flood-zone designation, and what it requires of a buyer, may be about to change.

This page covers what's specific to Reno County. For the general explanation, see the national guide.

Reno County's flood zones, and why the maps are in transition right now

FEMA flood-zone designations that apply in Reno County span the standard range used nationally: Zone AE, the high-risk designation carrying a 1% annual chance of flooding where flood insurance is required for federally backed mortgages; Zone X (shaded), a moderate-risk designation covering the broader 500-year floodplain; and Zone X, the low-risk designation for land outside the mapped floodplains. Hutchinson, the county seat and largest city, sits directly along the Arkansas River, which is the primary flood-risk corridor running through the county's most developed area.

What makes Reno County's flood-zone status genuinely worth double-checking right now is that the county has draft floodplain mapping data in circulation as of March 2026, alongside the currently effective floodplain maps most recently updated in April 2026 -- meaning FEMA's flood-zone boundaries here are actively being revised, not settled. A parcel that currently sits outside a mapped floodplain under the effective map could be pulled into one under the draft revision, or vice versa. Before buying, check a specific parcel against both the current effective map and the draft update, since relying on only one could give a materially incomplete picture of the property's actual and near-future flood-insurance and permitting obligations.

Permits, insurance, and what to verify before you buy

Reno County requires a floodplain-development permit for any structure located within a mapped floodplain, regardless of that structure's size -- including small accessory buildings of 120 square feet or less that are otherwise exempt from needing a standard zoning permit anywhere else in the county. That means even a modest shed, pump house, or barn on flood-prone acreage needs separate floodplain sign-off from the Planning & Zoning Division before construction, on top of whatever zoning permit would otherwise apply. Elevation requirements, floodway-versus-flood-fringe distinctions, and any building restrictions specific to a mapped zone are set out in the county's floodplain-management regulations, administered by the same office.

Before purchasing land anywhere near the Arkansas River corridor or another mapped waterway in Reno County, pull the parcel's current flood-zone designation from the Kansas Floodplain Viewer and cross-check it against Reno County's own draft floodplain data, then confirm directly with the county's Planning & Zoning Division (620-694-2978) whether the draft map has been finalized or adopted since this review. If a lender requires flood insurance based on a Zone AE designation, ask whether an elevation certificate exists or would be needed for the specific structure -- a certificate showing the lowest floor sits above the base flood elevation can meaningfully affect the insurance premium and, in some cases, whether a mortgage lender requires coverage at all.
