How Refugio County floods

Flash flooding from summer thunderstorms and tropical weather events dominates the flood risk in Refugio County, supported by 45 flash flood events and multiple tropical storms and storm surge incidents recorded over the last 30 years. Recent impacts include Tropical Storm Harold in August 2023 and Tropical Storm Nicholas in September 2021, which brought significant low pressure systems, coastal storm force gusts, and heavy rainfall to the Middle Texas coast.

National Flood Insurance Program records indicate that property damage occurs across multiple flood zones. Zone A accounts for 49 claims with an average payout of $19,896 and an average recorded water depth of 2 inches. Meanwhile, various designations of Zone X account for a combined 70 claims, with Zone X recording an average payout of $41,924 and 1 inch of water depth, unshaded Zone X recording an average payout of $11,011 and 2 inches of water depth, and shaded Zone X recording an average payout of $21,076 and 4 inches of water depth.

Homeowners and real estate agents in both designated high-risk Zone A and moderate-to-low risk Zone X areas should pay close attention to these flood risks, as properties in both zones have experienced recorded water depths and substantial insurance claims from historical storm events.

Where the flood claims came from

From the storm reports

Tropical Storm · Aug 22, 2023. Tropical Storm Harold moved west across south Texas on the 22nd. An area of low pressure developed over the central Gulf of Mexico on the 21st. A large area of high pressure over the central United States into the northern Gulf Coast steered the system quickly westward toward the Middle Texas coast. The low strengthened into Tropical Storm Harold by the early morning hours of the 22nd. Harold increased in strength…

Flash Flood · May 16, 2021. A series of disturbances moving across South Texas produced a line of showers and thunderstorms that moved across the Coastal Bend and towards the Middle Texas Coast throughout the day on the 16th. Locally heavy rainfall led to flooding of roads in Beeville, Port Aransas, and Rockport. Fast-moving water from heavy rain in a drainage ditch in Victoria resulted in one direct fatality.

Storm Surge/Tide · Sep 13, 2021. An area of low pressure over the western Caribbean Sea on September 9th moved west into the Bay of Campeche by the 11th. The low pressure area strengthened to become Tropical Storm Nicholas over the southern Gulf of Mexico on the morning of the 12th. Nicholas moved northward across the western Gulf of Mexico to the lower Texas coastal waters early on the 13th. Tropical storm force gusts reached the Middle Texas co…

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 Refugio County

If a building in Refugio 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.
