A new website launched on Monday that shows the flood risk for every property in the contiguous United States, allowing users to search by address to see if their home or a home they’re considering buying has a high probability for flooding.

Powered by new flood risk data and technology, Flood Factor weighs the impacts of climate change, rain, storms, rising sea levels, and more to assess a property’s current and future flood risk on a 1 (low risk) to 10 (high risk) scale. It uses decades of peer-reviewed research to give a property’s total risk of flooding during a typical 30-year mortgage period.

“Flood Factor is a free, online tool that makes it easy to learn if a property has flooded from major events in the past, is currently at risk, and how that risk changes over time. Flood Factor simplifies flooding so anyone can find their risk, understand the science, and make informed decisions to prepare for the future,” the website states. The tool does this by using a “first-of-its-kind flood model that calculates risk over time based on a changing environment.”

According to the tool, flood risk is increasing across Houston, and 30% of properties are at risk.

“As sea levels rise and weather patterns change, flood risks will increase. Approximately 186,484 properties are already at risk in Houston, and within 30 years, about 202,320 will be at risk,” the website says.

Additionally, this data evaluation of flood risk found that federal maps underestimate the number of homes and businesses that are at significant risk of flooding by 67%.

With this new data, the hope is that homebuyers and homeowners can make more informed decisions about their properties and if they should invest in flood insurance.
