Your specific zone determines insurance cost, build elevation, and permit requirements in Sarpy County, NE.

Full Breakdown

Sarpy County participates in the National Flood Insurance Program and administers floodplain management under Section 29 of its zoning regulations; cities like Bellevue, Papillion, and La Vista run their own programs. Development, fill, or substantial improvement within a FEMA special flood hazard area needs a floodplain development permit first, issued by the County Planning Director. New and substantially improved residential structures must have the lowest floor, including basement, elevated to one foot above base flood elevation. Flood risk here is riverine, driven by the Platte, the Missouri, and Papillion Creek, as the devastating March 2019 flooding along the rivers made painfully clear.

Violations & Fines

Building or filling in a special flood hazard area without a permit is a misdemeanor under state law, with each day a separate offense, plus correction orders and higher flood insurance.
