How Falls County floods

Flash flooding from severe weather events dominates the flood history of Falls County, accounting for 36 out of 43 total recorded flood events over the last 30 years, alongside 7 general flood events resulting in 1 death.

Recent occurrences illustrate these patterns. Multiple rounds of thunderstorms from a deep low pressure system produced flooding on April 9–10, 2024, following a total solar eclipse. A slow-moving front generated additional heavy rain and flooding across Central Texas on May 16, 2024. Another severe weather event on May 6, 2025, involved thunderstorms, large hail, damaging winds, and tornadoes.

National Flood Insurance Program claims data shows claims filed across different zones. Zone A recorded 7 claims with an average payout of $16,155 and an average recorded water depth of 4 inches. Zone UNKNOWN recorded 1 claim averaging a $5,957 payout and an average recorded water depth of 2 inches. Zone X recorded 1 claim with an average payout of $58,641 and an average recorded water depth of 0 inches. Homeowners and real estate agents with properties located in designated flood hazard areas, such as Zone A, should pay the closest attention to flood risk and mitigation.

Flood insurance in Falls County

If a building in Falls 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.
