This bill directs U.S. Customs and Border Protection to evaluate how hazardous weather and water events, such as hurricanes, winter storms, extreme heat, wildfires, and flooding, have affected its agents, officers, technology, vehicles, and infrastructure over the past five years, with a report due to Congress within 180 days of enactment. It then requires the Department of Homeland Security to develop, within one year, a formal strategy for mitigating these weather-related impacts on border operations and personnel safety, in consultation with agencies like NOAA, the General Services Administration, and Health and Human Services, as well as border-state governors, tribal governments, and CBP employee representatives. The strategy must include a cost-benefit analysis, and DHS must begin implementing it within a year of submission, followed by semiannual progress reports to Congress for five years. Separately, CBP must establish safety protocols within one year to protect personnel and infrastructure during extreme weather. The bill primarily affects CBP employees, border-crossing travelers, and border communities, and notably authorizes no new funding, meaning all requirements must be carried out using existing agency budgets.
