What are FEMA flood zones?
FEMA classifies properties into flood zones based on flood probability. The local percentage shown on this page comes only from rated-zone values recorded in historical NFIP claims and is not a complete current map inventory. Check a specific address on FEMA's Flood Map Service Center.
How are flood insurance claims calculated?
The NFIP dataset records insurance claims and reported building, contents, and ICC payment components. A claim is an insurance record, not a one-to-one count of flood events or a current property-level risk classification.
Flood Risk Overview

Understanding Flood Zones
FEMA classifies areas into flood zones based on risk:
| Zone | Risk Level | Description |
|---|---|---|
| A, AE, AH, AO | High | 1% annual chance of flooding (100-year floodplain) |
| V, VE | Very High | Coastal areas with wave action |
| B, X (shaded) | Moderate | 0.2% annual chance (500-year floodplain) |
| C, X (unshaded) | Low | Minimal flood risk |
Important: Even "low risk" areas experience flooding. Over 40% of NFIP claims come from outside high-risk zones.
Flood Insurance in Fresno
Standard homeowner's insurance does not cover flood damage. Options include:
National Flood Insurance Program (NFIP)

- Maximum coverage: $250,000 for building, $100,000 for contents

Required? If you have a federally backed mortgage and are in a Special Flood Hazard Area (SFHA), flood insurance is mandatory.
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.
