The REAADI for Disasters Act is designed to make sure that older adults and people with disabilities are better prepared for, protected during, and included in disaster response and recovery efforts. Right now, these groups face higher death rates during disasters and often don't get the information, shelter accommodations, or support they need when emergencies happen. This bill addresses that by requiring disaster planning and services to be accessible—meaning evacuation orders need to be available in American Sign Language and plain language, emergency shelters must have proper accommodations instead of segregating people with disabilities, and disaster relief agencies must include people with disabilities and older adults as decision-makers, not just afterthoughts. The bill also creates new federal funding through a Disaster Human Services Emergency Fund to help states, local governments, and nonprofits build their capacity to serve these vulnerable populations before, during, and after disasters. It establishes regional centers that will provide training and research to help government agencies and disaster relief organizations do a better job of protecting civil rights and meeting the needs of people with disabilities and older adults during emergencies.
