Moderate-risk zones (B/X shaded) have a 0.2% annual chance. Even in low-risk zones, about 25% of all flood claims come from areas outside designated high-risk zones. Covina has 67% of ZIP codes in designated flood zones.

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.
