Here’s a glimpse into our vulnerable future:
1.8 feet: How much higher the Anacostia and Potomac rivers could rise by 2050.
49 percent: Chance that a flood exceeding today’s record (7.9 feet above the local high-tide line) will occur by 2040 in Climate Central’s medium-risk scenario. In the organization’s worst-case scenario, floods of this level will become annual events by 2100.
What would such flooding affect? In the District, here are the things situated no higher than six feet above the high-tide line:
- Property totaling $4.6 billion
- 1,400 people in 400 homes
- 21 miles of road
- The National Museum of the US Navy
- Six hazardous-waste sites
- Portions of three Zip codes—20024 (Southwest DC), 20019 (Greenway), and 20372 (Foggy Bottom).
Here are a few landmarks that would be at least partially submerged in a flood ten feet above the high-tide line (which Climate Central predicts will likely occur by 2100):
Washington Navy Yard
Joint Base Anacostia-Bolling
