Here at First Street, we believe the best way coastal communities can protect themselves against the threat of sea level rise is with the full knowledge of their risk. This is why we created Flood iQ- to protect people when they are making one of the biggest financial decisions in their life: buying and selling homes. Our hope is that when we are done, no one in the U.S. will ever buy or sell a house again without having full knowledge of the impact that sea level rise has on their home.

Nevertheless, we’re aware of the potential negative impacts Flood iQ could have. Flood iQ shows very clearly and accurately how much home value has been lost to sea level rise since 2005, and how much more will be lost in the next 15 years if action is not taken.

This information has the potential to affect the sale price of a home. It could also accelerate the changes already taking place in the current valuation of the real estate market, as it adjusts to incorporate sea level rise risk. While we realize the potential of our tool to impact the real estate market, our goal is to help coastal communities and the people who live it.

It is a tough spot to be in, but we believe Flood iQ is the most effective and efficient way we can help protect our coasts and our real estate for the long run. Here’s why:

  • Homes are losing value because of sea level rise flooding, either because the homes flood directly or are in proximity to roads that frequently flood. Home values will continue to be affected regardless of Flood iQ’s quantification of the loss. Yet without Flood iQ, homeowners have no way of knowing the impact that their risk of flooding has on their home value. By shining a light on an already existing problem, Flood iQ serves as a necessary first step for homeowners to understand their risks, so they can find solutions.

The real risk sea level rise poses to the coastal real estate market isn’t the relatively-minor short-term correction in home values from flooding.

Rather, the risk is that property value estimates continue to exclude flood risks, causing the market to become overvalued, creating a bubble that will ultimately burst when the impact flooding has on homes becomes too severe to ignore. Towns and cities would then have reduced property taxes, causing downgraded credit ratings, which would limit their ability to finance the infrastructure needed to mitigate flooding, exacerbating the issue further.

It’s a bleak scenario, but we see Flood iQ as part of the solution to ensure this future event never happens.

With Flood iQ, the risk sea level rise poses to property values is transparent. Cities now have more information to better protect themselves, and greater incentive to do so. Investment decisions can be made with data and shifted to protect against or avoid flooding where it makes economic sense to do so. And, most significantly, homebuyers no longer risk purchasing a home in February unaware it will flood 10 times come October.

Protecting people with homes on the market today by keeping information out of the hands of potential buyers is unethical. Institutional and sophisticated real estate investment groups already have access to this type of data, which can be cost-prohibitive to many homeowners and homebuyers.

Should everyday citizens not be privy to the same risk knowledge that groups with more resources have?

That’s why we’ve decided to make this information public, free, and easy to access via Flood iQ’s new property value feature.

The sooner property-level sea level rise data is accessible to the general public, the more people we can protect from unknowingly making risky property investments.

That’s how we see Flood iQ: as part of the solution for a smarter, fairer, and more resilient approach to flooding in coastal communities.
