After flooding events, monitor your utility's website and local news for boil water advisories.
Flood Damage Prevention
Steps to reduce flood damage to your home:
- Install a sump pump with battery backup
- Elevate utilities (furnace, water heater, electrical panel) above potential flood levels
- Apply waterproof sealant to basement walls and floors
- Maintain gutters and drains to direct water away from foundations
- Consider flood vents in foundation walls
