Data: FEMA National Flood Insurance Program (NFIP), FEMA Hazard Mitigation Last verified: 2026-05-03
Across Lavaca, the National Flood Insurance Program has recorded 21 claims tied to flood-related property losses. Because flood protection sits entirely outside the scope of standard home insurance, property owners who want that coverage must arrange it separately — either through the NFIP directly or through a private flood insurer. That purchase is distinct from a homeowner policy and must be initiated separately.
What are FEMA flood zones?
FEMA classifies areas into flood zones based on the probability of flooding. High-risk zones (A and V) have a 1% annual chance of flooding and require flood insurance for federally-backed mortgages. Moderate-risk zones (B/X shaded) have a 0.2% annual chance. Even in low-risk zones, about 25% of all flood claims come from areas outside designated high-risk zones. Lavaca has 1% of ZIP codes in designated flood zones.
How are flood insurance claims calculated?
FEMA tracks every claim filed through the National Flood Insurance Program (NFIP). Claims data includes payouts for building damage and contents loss. High claim counts in an area indicate actual flood events, not just theoretical risk. Lavaca has 21 recorded claims — this real-world history is often a better risk indicator than flood zone maps alone.

How Flooding Affects Drinking Water
Flooding poses direct threats to drinking water quality:
- Water treatment plant overflow — systems can be overwhelmed, leading to untreated or partially treated water
- Sewage contamination — floodwater mixes with sewage systems, introducing bacteria and pathogens
- Agricultural runoff — pesticides, fertilizers, and animal waste enter water supplies
- Well contamination — private wells are especially vulnerable to floodwater infiltration
- Infrastructure damage — pipes can break, creating entry points for contaminants
After a flood event, always follow local boil water advisories and avoid using tap water until the all-clear is given.
