Is that lot in Martinsburg in a flood zone? The Dixon County flood zone map answer comes from FEMA, and it is free to look up. FEMA's free Flood Map Service Center and the Dixon County parcel viewer answer it together.
We'll cover finding a Dixon County address on FEMA's map, what Zone A, AE and X mean, how the county viewer fits in, and what to do if the map looks wrong.
How to use the Dixon County flood zone map
The authoritative source for a Dixon County flood zone map is FEMA, so begin at the FEMA Flood Map Service Center. If a tract close to Concord has no street number yet, search the nearest road and pan to it. For an irregular lot near Concord, the National Flood Hazard Layer viewer is easier to use, which displays how much of a county parcel sits inside the zone. Next, the Dixon County Beacon site confirms which Dixon County parcel you're looking at. Laying the county parcel outline beside the FEMA shading displays whether a homesite near Concord sits above or inside the zone.
Opening the Dixon County parcel viewer
The county's own public map is the Dixon County Beacon site, built on Schneider Geospatial's Beacon platform, and it opens without an account for parcels in Concord and the rest of the county. Search a Ponca address on the county search page, read the report, then jump to the map to see that parcel's outline. If the official address for the Dixon County, NE map ever changes, our directory page carries the current link for Concord and the rest of the county.
What the flood zone letters mean
For a lot in Ponca, the label matters more than the color: A and V zones are Special Flood Hazard Areas, meaning FEMA estimates a 1-percent annual chance of flooding. Where a Dixon County tract displays Zone AE, there's a base flood elevation to compare a building against; in Zone A there isn't one. Shaded Zone X around Ponca is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Clear, unshaded X near Ponca is outside the 500-year floodplain.
Creeks, rivers and low ground in Dixon County
The Dixon County landscape includes Missouri River and Missouri National Recreational River, and that's where flood questions cluster. Don't assume a tract close to Concord is clear since its road frontage sits high. Small streams and ditches near Ponca may not be studied in detail can still flood; FEMA says moderate- and low-risk areas still carry risk.
Towns and land across Dixon County
From Ponca, the seat of the county, the map spreads out to Wakefield, Allen, Concord, and Dixon. Unincorporated communities in the county, including Lime Grove, show up as small groups of parcels along the roads. Census Bureau estimates put Dixon County at about 5,491 residents in 2023 on roughly 476 square miles of land. Outside Concord, most of the county map is farm, ranch or timber ground with large, irregular tracts. With a founding date of 1856, Dixon County has long chains of title on some rural tracts.
Deeds and plats behind the Dixon County map
The parcel layer for Dixon County points back to recorded deeds and plats, kept by the county's recording office (its title varies by state). Easements and access rights near Allen live in recorded documents, so read the deed, not just the county map.
What a flood zone means for a Dixon County buyer
Lenders watch the zone closely on Dixon County properties. Where a building in Ponca falls inside an A or V zone and carries a federally backed mortgage, the lender must require flood coverage, provided the community near Ponca takes part in the National Flood Insurance Program. Outside the A zones around Concord, coverage is optional, although some lenders require it anyway. If a building near Concord sits above the flood line, a Letter of Map Amendment request is the formal route, supported by elevation data from a licensed surveyor. Placing fill on low ground near Ponca frequently requires a permit and an elevation check; the county floodplain administrator can say what applies.
