Ridgewood: Flood History & Water Damage Risk
FEMA data shows 100% of Ridgewood's ZIP codes mapped into designated flood zones, paired with an NFIP record of 417 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Ridgewood has a moderate flood history with 417 FEMA claims averaging $11,990 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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>$2,200</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.
