Wildfire hazard severity zones
CAL FIRE's current Fire Hazard Severity Zone maps do not designate any zones within Campbell. Individual properties near the boundary can still fall inside a neighboring zone — check the exact address on the map.
FEMA flood zones
2% of Campbell lies within a FEMA Special Flood Hazard Area (1% annual chance, zones A/AE/AH/AO); less than 1% is in the 0.2% annual chance (500-year) area. Federally backed mortgages in a Special Flood Hazard Area generally require flood insurance.
| Special Flood Hazard Area (100-yr) | 2% |
| 0.2% annual chance (500-yr) | less than 1% |
