California, Arizona and Colorado, along with 17 other states, sued the Trump administration this week over its decision to close the Federal Emergency Management Agency’s Building Resilient Infrastructure and Communities program.

The program, established by a 2000 law, provides grants for a variety of disaster mitigation efforts, including levees to protect against floods, safe rooms to provide shelter from tornadoes, vegetation management to reduce damage from fires and seismic retrofitting to fortify buildings for earthquakes.
