The Trump administration plans to all but eliminate the office that oversees America’s recovery from the largest disasters, raising questions about how the United States will rebuild from hurricanes, wildfires and other calamities made worse by climate change.

The Office of Community Planning and Development, part of the Department of Housing and Urban Development, pays to rebuild homes and other recovery efforts after the country’s worst disasters, such as Hurricane Helene in North Carolina and Hurricane Milton in Florida.

The administration plans to cut the staff in that office by 84 percent, according to a document obtained by The New York Times. The number of workers would be cut to 150, from 936 when Mr. Trump took office last month.

Those cuts could slow the distribution of recovery money to North Carolina and other recent disasters, depending how quickly they happen.

“HUD is carrying out President Trump’s broader efforts to restructure and streamline the federal government to serve the American people at the highest standard,” a spokeswoman for the department, Kasey Lovett, said in a statement.

The primary responsibility for rebuilding communities after major disasters falls to the Federal Emergency Management Agency, which helps state and local governments pay to repair or rebuild damaged roads, bridges, schools, water treatments plants and other public infrastructure. The agency also provides money to help repair damaged homes.
