Summary
Nebraska is landlocked, so no coastal law applies. Building near the Platte River, Missouri River, or the Papillion Creek system instead triggers county floodplain permits and federal Army Corps wetland review.
Filling of the flood fringe associated with new development within the Papillion Creek System shall be limited to 25% of the flood fringe in the floodplain development application project area, unless approved mitigation measures are implemented.
Full Breakdown
There is no coastal zone in Sarpy County; Nebraska has no ocean and no coastal management act. Waterfront rules here are floodplain and federal. Placing fill or dredging in the Platte River, Missouri River, Papillion Creek, or adjacent wetlands, waters of the United States, requires a Clean Water Act Section 404 permit from the U.S. Army Corps of Engineers. Development inside the mapped floodplain needs a Sarpy County floodplain development permit, and within the Papillion Creek system filling the flood fringe is capped to protect flood storage. The Papio-Missouri River Natural Resources District reviews and comments on many of these applications.
Violations & Fines
Filling wetlands or waters without a Corps Section 404 permit draws federal enforcement and restoration orders. Unpermitted floodplain fill brings county correction and removal orders.
