Summary

Kansas is landlocked, so no coastal program exists anywhere in the state. Development near water in Overland Park runs through FEMA floodplain permits under OPMC 18.360, stream corridor setbacks under 18.365, and Corps Section 404 approval where wetlands are disturbed.

No person, firm, corporation, or unit of government shall initiate any development or substantial-improvement or cause the same to be done without first obtaining a separate floodplain development permit for each structure or other development.

Full Breakdown

Overland Park has no coast and no coastal management agency. The Special Flood Hazard Area is a zoning district enacted under K.S.A. 12-753 and K.S.A. 12-766, mapped by the Flood Insurance Rate Maps dated August 3, 2009. A floodplain development permit from the Director of Planning and Development Services, the designated Floodplain Administrator, precedes any construction there, and the usual small-project land disturbance exemption does not apply inside the flood hazard area. Lowest floors sit two feet above base flood elevation. Nothing may raise base flood elevation inside the floodway. Blue River, Indian Creek, Tomahawk Creek, Coffee Creek and Turkey Creek drain the city.

Violations & Fines

Floodplain violations are misdemeanors under OPMC 18.100.110: fines up to $500, imprisonment up to six months, each day a separate offense, plus injunction and abatement suits.

Frequently Asked Questions

Does Overland Park require a coastal development permit?
No. Kansas has no coastline and no coastal management program. Work near water requires a floodplain development permit under OPMC 18.360 plus stream corridor compliance under 18.365.
How high must a home in the floodplain be built?
The lowest floor, including basement, sits at least two feet above base flood elevation. Mechanical and HVAC equipment is elevated or floodproofed to that same level.
How close to a creek can I build?
Buildings keep at least 40 feet from a stream's ordinary high water mark. Dedicated stream corridors run 30 to 120 feet on each side, scaled to tributary drainage area.
