How Caldwell Parish floods

Caldwell Parish experiences a flood risk profile dominated by flash flooding, accounting for 20 of the 29 recorded flood events over the last 30 years, alongside tropical storm and river flood impacts. This hazard is driven by severe weather systems, such as major hurricanes impacting the region, which bring intense rainfall and subsequent flooding. For example, Major Hurricane Laura tracked north across Louisiana on August 27, 2020, followed closely by Hurricane Delta and associated flash flooding on October 10, 2020.

National Flood Insurance Program records indicate that historical claims are heavily concentrated in specific areas. Zone A properties should pay the most attention, accounting for 444 total claims with an average payout of $11,558 and an average recorded water depth of 6 inches. Properties located in Zone X, shaded Zone X, unshaded Zone X, and unknown zones have experienced fewer claims—ranging between 10 and 15 claims per zone—though they recorded higher average payouts, ranging from $17,350 to $28,057, with an average recorded water depth of 2 inches.

Where the flood claims came from

From the storm reports

Tropical Storm · Aug 27, 2020. Major Hurricane Laura tracked north northwest across the Central and Northern Gulf of Mexico from the Central Carribean Sea near Cuba, making landfall in Southwest Louisiana near Cameron around 1 am on August 27th as a strong Category 4 hurricane with maximum sustained winds near 150 mph, and a minimum central pressure of 938 mb. Laura remained a hurricane as it tracked north across Southwest and Central Louisiana…

Flash Flood · Oct 10, 2020. Hurricane Delta tracked north northwest across the Western Carribean Sea as a major hurricane, having rapidly strengthened from a tropical depression to a Category 4 hurricane in just over 36 hours, the fastest intensification rate on record. Delta made its first landfall across the Yucatan Peninsula near Cancun on October 7th, before tracking north and making a second landfall near Creole, Louisiana in Cameron Pa…

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 Caldwell Parish

If a building in Caldwell Parish 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.
