Full Breakdown

K.S.A. 12-734 authorizes communities to adopt floodplain regulations and requires participation in the National Flood Insurance Program for federal flood insurance availability. The Division of Water Resources within the Kansas Department of Agriculture oversees floodplain permits for construction in regulated floodways under K.S.A. 24-126. New residential structures must be elevated to or above base flood elevation, nonresidential structures elevated or floodproofed, and substantial improvements meeting current standards. Local ordinances must meet FEMA minimums; stricter rules are allowed but waivers are not.

Violations & Penalties

Unpermitted floodplain construction risks denial of flood insurance, FEMA probation or suspension, removal orders, and civil penalties under state water and floodplain regulation statutes.

Frequently Asked Questions

Do I need a permit to build in a Kansas floodplain?

Yes. Both local floodplain administrators and, for floodway work, the Kansas Division of Water Resources must approve construction under state and NFIP standards.

Can Kansas cities allow construction below base flood elevation?

No. Communities must enforce FEMA minimum elevation or floodproofing standards to remain in the NFIP and keep flood insurance available.
