The 5 Types of Flooding
⚡Flash Floods
Deadliest

Fast-moving walls of water with <30 min warning. Responsible for 80–90% of all flood fatalities. 145 deaths in 2024 alone.

🌊River / Riverine Floods
Most Common

Rivers overflow their banks after heavy rain or snowmelt. Slower to develop but enormous damage potential across wide areas.

🏖️Coastal Floods
Rising Risk

Storm surge, high tides, and sea-level rise. Affecting more communities annually as ocean levels climb.

🏙️Urban / Stormwater Floods
Often Overlooked

Overwhelmed storm drains and impervious surfaces. Basements and streets flood in heavy rain — no "flood zone" required.

🏚️Basement Floods
98% Lifetime Risk

98% of U.S. basements will experience flooding. Primary causes: sump pump failure, cracks, sewer backup, and surface water.
