Briscoe County, Texas Flood Zone Map

1 federal flood & hurricane disasters

FEMA’s digital flood map shows no high- or moderate-risk zones in Briscoe County. That can mean the area was never studied in detail or has no digital map, not that it can’t flood; the county floodplain administrator can say which.

Share of the whole county outline, rivers and lakes included; parts FEMA hasn’t mapped count as zero.

From the storm reports

Flash Flood · Jul 17, 2021. An upper level trough moved across the region during the afternoon of the 15th. This trough was also accompanied by a surface cold front that led to scattered thunderstorm development during the afternoon and evening hours. Ample atmospheric moisture combined with weak wind shear lead to slow moving efficient rain producers which led to several heavy rain reports. Additionally, very hot surface temperatures were c…

Flood · Oct 8, 2018. Early morning showers and thunderstorms across much of the South Plains were followed by additional rounds of heavy rainfall through midday. The latter rounds of rain were focused near and just east of the Interstate 27 and US Highway 87 corridor where as much as two inches of rain fell on top of soils that were already saturated from heavy rains that fell just three days earlier. The result was widespread floodi…

Flood · Oct 4, 2017. Beginning on the evening of the 4th and lasting through the early morning of the 5th, very heavy rains fell over portions of eastern Briscoe, Hall, and western Childress Counties. A very moist atmosphere in place and training convection allowed for an estimated swath of 5-7 inches of rainfall over a widespread area. A river gauge six miles southwest of Brice in Hall County recorded a rainfall amount of 5.71 inches…

Flood · Apr 22, 2015. Early this morning, a series of outflow boundaries moved south across the southern Texas Panhandle and much of the Rolling Plains. The most organized of these boundaries would eventually retreat north before stalling from near Hereford (Deaf Smith County, WFO AMA) southeast to Paducah (Cottle County). This boundary provided the focus for an intense and long-lived supercell that developed west of Hereford by mid-af…

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Cross-section of a river floodplainDiagram: a river valley. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Briscoe County

If a building in Briscoe County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
