A new report finds that 25% of all critical infrastructure in the United States is at risk of failure due to flooding.

Today, one-fourth of all critical infrastructure in the United States পুলিশ including police and fire stations, hospitals, airports, and wastewater treatment facilities যথেষ্ট is at considerable risk of being disrupted by flooding, according to a new report released today by the Street Foundation, a nonprofit study and Technology Group that assesses the threat posed by floods across the country.

The report further found that about 2 million miles of roads – 23% of U.S. roads – are already at risk of becoming inaccessible due to flooding.

To provide a full picture of what Community Street-level flood risk dates say, researchers have examined the following 48 and five sections across the District of Columbia: complex infrastructure; Including social infrastructure, museums, government buildings and schools; Road; Commercial properties And residential property.

The report uses operational flood risk estimates from the official governing body to determine how much flooding is needed to push a variety of facilities or services offline. Researchers can then assess the community’s risk of flooding at least once every two years.

Past reports from First Street have focused on the unknown risks of flooding faced by U.S. homeowners, and many of them have or often do not have adequate flood insurance coverage. Experts say the widespread assessment, like the new report, is critical because of the country’s weight on how to adapt to a climate-changing future.

“Even if your home is safe and secure from a certain severity of the flood, if the flood becomes more common and destructive in your community, the value of your property could also be threatened,” said Hamid Moftakhari, an assistant professor in the university’s Department of Environmental Engineering. Alabama, who was not involved in the first street report.

Where the risk of flood is highest today

If there is a ground zero for flood risk in the United States, it is Louisiana.

There are six states in the top 20 risky counties in the country. Cameron Parish in southwestern Louisiana is the most risky county in the United States, followed by Orleans Parish, which includes New Orleans.

Jeremy Porter, head of research and development at First Street, said while New Orleans has its infrastructure and levees to prevent strong storms, continued sea level rise and more destructive hurricanes could eventually defeat the city’s current defenses.

“It needs to be constantly updated as the environment changes in the future,” Porter said. “The infrastructure we have today will not protect New Orleans in five, 10, 15 years. It’s getting worse as sea levels rise, because storms don’t get more frequent, they get stronger.”

In both Cameron and Orleans parishes, the report found more than 94% – including police and fire stations, which are important for emergency response after disasters like hurricanes – are at risk of falling offline.

Florida is home to some of the most flood-prone counties in the country, but flood risk is not limited to coastal areas. Many areas of Appalachia, such as McDowell County in Virginia and Johnson County in Kentucky, are also at the highest risk, First Street researchers said.

As the planet warms due to man-made climate change, a warmer atmosphere can hold more water, dumping large amounts of water in a short period of time in the event of heavy rainfall.

Floods are already the most common and costly disaster in the United States, according to congressional testimony from FEMA Deputy Associate Administrator David Morstad.

“Because of the effects of climate change, there are some communities in the United States that are going to make difficult decisions in the coming years due to rising sea levels and the intensity of storms,” ​​Maurastad told CNN. “It’s not just the Louisiana coast.”

A bill to help reduce the risk of flooding

President Joe Biden’s $ 1.2 trillion bilateral infrastructure bill includes billions for flood mitigation and coastal recovery from storms. The Senate version of the bill includes $ 7 billion for the Army Corps of Engineers and 3.5 3.5 billion for the FEMA flood mitigation assistance program, as well as millions more for the National Oceanic and Atmospheric Administration program to make coastal communities more resilient to storms.

The bilateral bill contains billions of dollars to improve road and power infrastructure and make the energy grid resilient for more modern and powerful storms.

The bill was partly debated by Republican Sen. Louisiana Bill Cassidy, who says it will help recover vulnerable coastal populations from storms and prepare them for the future.

But Cassidy’s fellow Republicans disagree between the House and Senate. Louisiana House Minority Whip Steve Scalis, who represents three of the top five communities in the U.S. most at risk of flooding, is opposed to the bill.

Rep. Troy Carter, the only Democratic member of Congress in Louisiana, told CNN in a statement that he would like to see the infrastructure bill passed.

“I’m hopeful that our Louisiana delegation won’t throw the bilateral history of infrastructure talks out of the window,” Carter told CNN. “I am grateful that Sen. Cassidy has stood by me in this endeavor. I do not plan to return to my constituency empty-handed.”

Clay Higgins, a spokeswoman for Scalise and Rep-a Republican who represents Cameron Parish-did not return CNN’s requests for comment on how they would like to help flood-prone communities in their district.

It’s going to get worse

The risk of flooding in the United States is growing rapidly. One devastating flood this summer has killed dozens of people and caused billions of dollars in damage from Louisiana to Tennessee and New York City.

And as global warming melts ice sheets, raises sea levels and increases the risk of further extreme rainfall, the risk will increase among many more communities, the First Street report found.

Over the next 30 years, the number of residential properties at risk of flooding is expected to rise from 12.4 million today to 13.6 million by 2051, the report said. For critical infrastructure and commercial properties, the number of risky facilities is expected to increase by 6% and 7%, respectively, over the next three decades.

Geographically, the report found that the Atlantic and Gulf coasts would be most at risk of flooding, but also predicted a significant increase in vulnerabilities across much of the Pacific Northwest.
