This national analysis identifies when US coastal communities will face a level of disruptive flooding that affects people's homes, daily routines, and livelihoods. It identifies hundreds of communities that will face chronic inundation and possible retreat over the coming decades as sea levels rise.
The findings highlight what’s at stake in efforts to address sea level rise and global warming. They also provide affected communities a measure of how much time they have to prepare. The solutions that can help protect individual communities from increased flooding fall into three broad categories: defending against the sea, accommodating rising water, and retreating from flood-prone areas. In practice, many communities will seek to combine these approaches. Not all approaches will work everywhere. Many are costly to sustain, and rising seas may simply preclude some options.
Robust federal and state-level policies and resources will be vital to help communities understand their risks, assess their choices, and implement adaptation plans. To effectively prepare, the country must take bold measures commensurate with the scale of the coastal risks.
