About 25%, or 1 in 4 units of critical infrastructure, such as police stations, airports and hospitals, are at risk of being rendered inoperable due to flooding, a comprehensive new report finds. The report points to climate change for heightening risks.

Why it matters: The new national inventory of flood risk during the next thirty years, which takes into account climate change-driven increases in sea levels and heavy precipitation events, is the first of its kind.

• The report, from the First Street Foundation, a nonprofit flood research and communications group, presents a stark warning to communities of all sizes — the U.S. simply isn’t ready for the climate of today, let alone the extreme weather and climate events that are coming in the next few decades.
• Specifically, during the next 30 years as the climate continues to warm, the flood risk situation will grow more dire, the report warns.

By the numbers: Consider these aggregate statistics from the “Infrastructure on the Brink” report:

• About 2 million miles of road are currently at risk of becoming “impassable” due to flooding.
• Nearly a million commercial properties, 17% of all social infrastructure facilities, and 12.4 million residential properties also have “operational risk,” according to the First Street analysis.
• Over the next 30 years, the typical lifetime of a home mortgage, about 1.2 million residential properties, and 2,000 pieces of critical infrastructure (airports, hospitals, fire stations, hazardous waste sites and power plants) will also be at risk of becoming inoperable due to flooding from sea level rise, heavy rainfall, and in some cases a combination of the two, the report finds.
