FEMA’s digital flood map shows no high- or moderate-risk zones in Hartley 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

Flood · Jun 5, 2019. Upper level disturbance over eastern New Mexico helped to generate thunderstorms. Originally multi-cellular, thunderstorms quickly congealed into a line as they produced damaging winds gusts and hail reports across the central and western Texas Panhandle. Locally heavy rainfall in the most persistent areas of thunderstorms also produced reports of flooding for parts of the TX Panhandle.

Flash Flood · May 21, 2016. Thunderstorms developed in a favorable environment to intensity during the afternoon and evening hours of the 21st. They affected mainly the western portion of the Texas Panhandle. Some locations, including Dalhart and Hartley, received two or more hail storms. Hail as large as two inches in diameter was reported.

Flash Flood · Jun 4, 2015. Slow moving thunderstorms developed during the afternoon over the northwestern Texas Panhandle and resulted in strong winds, hail and flooding. The most impactful weather was from flooding. A CO-OP Observer 1 mile southeast of Hartley reported a total of 5.05 inches of rain and locally higher amounts were indicated by radar rainfall estimates over portions of eastern Hartley County. This resulted in flooding inclu…

Flash Flood · Jun 22, 2006. Severe thunderstorms across the northern...western and central Texas panhandle produced damaging winds and hail during the evening hours. No injuries were reported.

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 Hartley County

If a building in Hartley 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.
