While floodplains account for approximately 25% of all ecosystem services benefits, they only make up 2% of Earth’s total land surface.

Floodplains The low-lying areas around rivers and other water bodies that regularly flood are called floodplains. Floodplains are the lifeblood of surrounding areas because of their frequent flooding.

They are a source of clean water and habitat for wildlife and have many other benefits. One of these is storing floodwater in large quantities and releasing it slowly over time.

We have seen more severe and frequent storms over the past century.

Americans have experienced a 20% increase in heavy downpours over the past 50 years. We know that the country’s floodplains are likely to grow by 40-45% over the next 90 years due to a changing climate. This will put more people at risk.

Flood losses are now causing damage of an average of $10 billion annually.

Extreme rainfall events and changes in land use combined with increased flood losses have led to an increase in floods in the first decade of the new millennium. This is despite billions of dollars being invested in flood control.

2011 saw 58 Federal flood disaster declarations. They cost over $8 billion and resulted in 113 deaths. Both were higher than the 30-year averages.

A 100-year flood is a statistical projection. It refers to a flood event with a 1 percent chance of occurring each year. The area and size of the 100-year flood zone will rise as the climate changes.
