Ahead of any purchase around Broadway, check the Crosby County flood zone map: the zone on that map shapes insurance, permits and resale. What this Crosby County guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and confirming the outline on the county map.
Checking the Crosby County flood zone map step by step
If you'd rather pan and zoom, try the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, which applies near Ralls as much as anywhere. Vacant ground around Crosbyton is still easy to locate: search the nearest road then click the parcel area.
Where the parcel data lives
Begin with the Crosby County parcel viewer; it covers each assessed parcel in the county, Broadway included. If you only know roughly where the land is, pan along the nearest road until the lines appear, then click inside the one you want, and that holds around Kalgary too. For a parcel near Cap Rock, the record panel usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
Getting your bearings
Crosbyton is the county seat, which is where the courthouse records live. You'll also find Lorenzo, Ralls, Broadway, and Cap Rock, where town lots give way to larger tracts. About 4,917 people call Crosby County home (Census estimate, 2023) across some 900 square miles. The county was organized in 1886, and some chains of title near Cone are long.
Decoding the flood zone labels
In and around Ralls, zones beginning with A or V are Special Flood Hazard Areas, meaning a 1% or greater chance of flooding each year. For property near Cone, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, is minimal risk.
Taking the map into the field
Most viewers work in a phone browser, useful out on a road near Lorenzo, but coverage can be spotty out of town. A saved image of the lot near Kalgary and its lines is a good backup.
When a parcel crosses a boundary
Crosby County meets Dickens County, Floyd County, Garza County, Hale County, and Kent County, and each of those keeps its own parcel map. Ground near Broadway that runs to the line can show up in two county records, so check the neighboring map as well. For a home near Broadway, the Platbookmapper state page links every neighboring county map for Texas.
A short flood checklist
For a parcel near Crosbyton, ask the listing agent for any Elevation Certificate before closing; getting a quote early keeps the budget honest.
Low spots and local drainage
Creeks and ditches near Kalgary may not have detailed mapping, so ask neighbors about past flooding. Marshy spots near Cap Rock can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Lining it up with the parcel map
Where a floodplain cuts across acreage near Broadway, the location of the house or building pad decides a lot.
Insurance, lenders and building
If a building sits in a Special Flood Hazard Area and a federally regulated lender is involved, mandatory purchase rules apply in communities in the NFIP, which applies near Kalgary as much as anywhere. Building or adding on near Broadway in a mapped zone often needs a floodplain permit; ask the local floodplain administrator before you plan.
Before you lean on the lines
For land near Cap Rock, acreage on the record is an assessed number; just a licensed surveyor establishes the real lines on the ground. On ground around Broadway, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Deeds, plats and who keeps them
For a home near Cone, the map is an index, not the title: deeds, subdivision plats and easements for parcels in the county sit with the County Clerk. Long-held tracts around Cone can trace back through several deeds, so a title company can sort it out if money is changing hands.
Legal descriptions in Texas
Rural deeds near Lorenzo are often described by metes and bounds, which trace the boundary call by call. Town lots near Kalgary usually use lot and block from a recorded plat instead, which is simpler to follow. Write down the legal description for the tract near Kalgary when you talk to a surveyor.
Frequently asked
What does an AE label mean for a lot near Cap Rock?
Usually, an AE zone has a 1% annual chance of flooding and a base flood elevation, so builders near Crosbyton design to that elevation.
What is a base flood elevation in Crosby County?
Good question; a BFE near Ralls tells builders how high the lowest floor should be, and an Elevation Certificate compares the building to it.
What is a LOMA near Kalgary?
For most people, FEMA's LOMA process is the usual route when a building near Estacado sits above the base flood elevation, and lenders accept the result.
Can I see flood zones on the Crosby County parcel viewer?
Generally, a flood layer may appear in the county parcel viewer layer list; confirm a lot near Crosbyton on FEMA's map either way.
Who do I call about a parcel near Estacado?
For acreage around Cap Rock, the appraisal district handles values and the tax roll, and the County Clerk keeps deeds.
