Where to see the official Cass County flood zone map
FEMA's official flood maps for Cass County are free at the FEMA Flood Map Service Center. Search returns the effective FIRM panel for the spot in Cass County, plus any pending changes FEMA has posted. On acreage outside Domino, the National Flood Hazard Layer viewer is easier to use, so you can see whether the shading reaches a house near Queen City. Switch to the Cass CAD interactive map and track down the same parcel near Queen City. Laying the county parcel outline beside the FEMA shading displays whether a homesite near Queen City sits above or inside the zone.
Finding the tract on the Cass County map
For land around Hughes Springs, open the Cass CAD interactive map (a BIS Consulting map viewer); it is the map Cass County itself publishes. Search the county appraisal map by owner, address or property ID; the pop-up for a parcel near Bloomburg displays the account and legal description. For a backup route to the map covering Hughes Springs, our Cass County directory entry keeps the link current.
Zone A, AE and X in plain English
On the FIRM covering Cass 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). Zone AE near Queen City means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. Land near Queen City in shaded X (Zone B on older maps) falls between the base flood and the 500-year flood. Clear, unshaded X near Domino is outside the 500-year floodplain.
Cass County land records
For land near Domino, the deed itself lives in the county recording office, and the map is an index to it. Property values in Cass County come from its appraisal district, a separate political subdivision with its own board that sets one value per property for every local taxing unit. Copy the parcel number and legal description from the county record before you request a deed for land near Linden.

Insurance, permits and map changes
Lenders watch the zone closely on Cass County properties. Where a building in Domino is mapped in a high-risk zone 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. Outside the A zones around Queen City, coverage is optional, although a lender in Texas can still ask for it. Where a structure near Domino looks higher than the shading suggests, FEMA's LOMA process allows a review; a surveyor near Queen City can supply the elevation data. Building or filling inside a mapped zone near Domino most commonly needs a floodplain permit, and the building office serving Queen City explains the steps.
