Look up the Ray County flood zone map step by step
Start at the FEMA Flood Map Service Center and enter the property address in Excelsior Springs or anywhere else in the county. If a tract near Richmond has no street number yet, search the nearest road and pan to it. For an interactive view of the county, the National Flood Hazard Layer viewer is easier to use and reports the zone wherever you click near Excelsior Springs. Then open the IntegrityGIS - Ray County for Ray County to confirm the parcel near Excelsior Springs. The Ray County record gives the parcel number and legal description that an insurer or lender near Excelsior Springs may ask for.

Towns and land across Ray County
From Richmond, the seat of the county, the map spreads out to Camden, Crystal Lakes, Excelsior Springs, and Fleming. Smaller places such as Rayville, Vibbard, and Albany appear on the Ray County map as little clusters of lots. Roughly 569 square miles of land and about 23,182 residents (2023 estimate) make up Ray County. Outside Fleming, most of the county map is farm, ranch or timber ground with large, irregular tracts.
High, moderate and minimal risk in Ray County
On the FIRM covering Ray County, zones that start with A or V are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any given year (the base or 100-year flood). A surveyor working near Excelsior Springs uses the base flood elevation printed for AE zones; unnumbered A zones do not have one. Shaded Zone X around Excelsior Springs is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Clear, unshaded X near Excelsior Springs is outside the 500-year floodplain.
Ray County land records
The parcel layer for Ray County points back to recorded deeds and plats, kept by the county's recording office (its title varies by state). A deed book and page or instrument number on the county record is the fastest way to order the document for a lot in Excelsior Springs.
Low ground and small streams around Excelsior Springs
A creek near Richmond that shows no detailed zone, so treat an unmapped channel as a reason to ask questions, not proof the ground stays dry.
When the map affects a deal
Lenders watch the zone closely on Ray County properties. When a structure near Richmond sits in a Special Flood Hazard Area and carries a federally backed mortgage, a flood policy becomes a loan condition under the Flood Disaster Protection Act, wherever the community joins the NFIP. In Zone X near Excelsior Springs, coverage is optional; pricing a policy for land near Richmond is still worth a call. If a building near Richmond sits above the flood line, the owner can ask FEMA for a Letter of Map Amendment (LOMA), typically backed by an elevation certificate from a surveyor who works in the county. New construction in a Ray County Special Flood Hazard Area has to meet local floodplain rules, so call the county or the town office in Excelsior Springs before work starts.
