Where Virginia homes face flood risk in next 30 years

The share of Richmond properties with a significant risk of flooding is projected to increase by 7% in the next 30 years, according to the nonprofit First Street Foundation.

• That could impact more than 5,100 city properties.

Why it matters: An extreme flooding risk is likely to affect people's daily lives and threaten access to emergency services, per First Street .

By the numbers: All Richmond-area localities face a projected increase in the number of homes facing flooding risk, but none are seeing more than a 5% jump, per the First Street data.

• It's a different story for Virginians near the coastline, especially those in Hampton Roads and the Northern Neck.
• York County has the biggest projected increase in the state at 62%, followed by Hampton (61%), Westmoreland (59%), Northumberland (55%) and Norfolk (53%).
• Only 12 localities will face less flood risk. Most are in Southwest Virginia.

State of play: Of the roughly 4,600 prospective homebuyers Zillow surveyed nationwide last spring, over 80% said they considered at least one climate risk when looking for a home.

• In the South, it was 79%.

Zoom in: Real estate websites have begun sharing more climate risk information with buyers and sellers.

• Realtor.com, which was the first major site to show a home's flood risk , added heat, wind and air-quality risks to listings last month.

Threat level: Nearly 45% of U.S. homes face the risk of severe or extreme damage from environmental threats , according to a new report from Realtor.com.

Between the lines : Climate change threatens to make homeownership more expensive, said Matthew Eby, First Street founder and CEO, at an SXSW panel last month.

• Millions nationwide may see higher insurance rates due to the risk of extreme weather , according to recent First Street modeling.
