Notable recent impacts include heavy rainfall and flash flooding from strong thunderstorms in May 2021, as well as catastrophic regional flooding produced by Tropical Storm Harvey in August 2017.

Meanwhile, Zone X properties have accounted for 15 claims with a higher average payout of $77,012 and an average recorded water depth of 4 inches.

From the storm reports

Flash Flood · May 28, 2021. Strong thunderstorms resulted in wind damage across Greater Houston and flash flooding in Burleson County.

Tropical Storm · Aug 25, 2017. Harvey made landfall as a category 4 hurricane near Rockport, Texas during the evening of August 25th. The storm then weakened to a tropical storm and slowed, looping back and tracking over SE Texas then back over the Gulf of Mexico making a second landfall along the Louisiana coast during the early morning hours of August 30th. Over that 5 day period over Southeast Texas TS Harvey produced catastrophic flooding…

Flash Flood · Oct 24, 2015. The remnants of Hurricane Patricia merged with a developing frontal low to produce an intense surface low off the Texas Gulf Coast. As this low moved up the upper Texas coast it produced moderate to heavy rainfall that broad flooding to some areas, an isolated tornado and waterspout, and minor coastal flooding due to elevated stormtides.

Flash Flood · May 6, 2015. An early morning slow moving thunderstorm produced some wind damage and flash flooding.

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.

Flood insurance in Burleson County

If a building in Burleson 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.
