The Insurance Gap Is Widening
NFIP coverage declined 2.4% from July 2023 to July 2024 — a loss of 87,159 policies. Only 3.6 million of 133.8 million U.S. buildings are insured against floods. Standard homeowners insurance does not cover flooding. A separate flood policy is required.

What This Means for You
The average NFIP flood insurance policy costs ~$800/year, but the average claim payout exceeds $30,000. Without coverage, a single flood event can be financially catastrophic — and federal disaster assistance averages just $5,000–$7,000 per household.
