Climate-Related Water Risk for Aransas Pass
NFIP data for Aransas Pass documents 864 flood insurance claims across the program's multi-decade tracking period, with 100% of ZIP codes mapped into FEMA flood zones. That level of exposure creates compounding risk during major flood events: treatment systems can be overwhelmed, wells can be contaminated, and distribution infrastructure can suffer backflow — all pathways by which flood events degrade local water quality beyond the physical damage.
Aransas Pass has a significant flood history with 864 FEMA flood insurance claims on record, averaging $9,159 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$2,000</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
