FEMA is already hunkering down for a years-long recovery effort in Texas after Hurricane Harvey, its chief said Sunday.

“FEMA is going to be there for years, sir. This disaster recovery — this disaster is going to be a landmark event,” Brock Long, the administrator for the Federal Emergency Management Agency, told CNN.

“We’re already pushing forward recovery housing teams. We’re already pushing forward forces to be on the ground to implement National Flood Insurance Program policies as well, and doing the inspections that we need. So, we’re setting up and gearing up for the next couple of years,” Long said.

Harvey hit the Texas Gulf Coast on Friday night, killing at least five people, and will continue to batter the Houston area with torrential rains for days.

Long was a FEMA hurricane manager during Hurricane Katrina but stressed Sunday that the two situations are “vastly different.”

“Every storm impacts different jurisdictions differently. Every Category 4 storm is different. This is a storm that the United States has not seen yet,” he said.
