Free, no account. Or open the Nebraska map and tap a lot.
Towns in Valley County: Ord.
Flood zone by address
ParcelSheet reads FEMA's National Flood Hazard Layer at the lot: the zone, whether it is a high risk area where lenders ask for flood insurance, and the base flood elevation where FEMA lists one. FEMA's countywide study for Valley County has 19 FIRM panels, the newest effective August 2008; no coastal V zones are mapped in it.
The official panel and any Letter of Map Amendment are at FEMA's Map Service Center. An elevation certificate for a Valley house comes from a licensed surveyor and is often on file with the county or city building office.
Property lines
The parcel outline, parcel number and mapped size come from the NebraskaMAP statewide parcel layer (from each county assessor), so a Valley lot shows the same lines the county assessor draws. Valley County covers about 363,578 acres of land and 1,516 acres of water.
Mapped lines are approximate. The Valley County assessor keeps the parcel record (Valley County website); a licensed surveyor sets the true corners.
Zoning
Valley County zones its unincorporated land, and Ord zones the land inside its limits. ParcelSheet shows the use the county assessor lists for the lot and links the county zoning office for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under Nebraska's county zoning law (Neb. Rev. Stat. 23-114) and each city's zoning powers, local governments can allow an accessory dwelling unit on a lot with a house. Whether a Valley lot can add one depends on its district; the county zoning office has the rule. ParcelSheet shows the mapped lot size and the ground's slope, the first two things the question turns on.
Septic and soil
ParcelSheet reads the USDA soil survey at the lot: the soil's name, its septic absorption rating and whether it is prime farmland. Valley County is soil survey area NE175, Valley County, Nebraska, last updated September 2026, on Web Soil Survey.
A new or changed septic system in Valley County must be registered with the Nebraska Department of Environment and Energy onsite wastewater program (Title 124).
Setbacks

Hazards that apply
