(CNN) — Rescuers brought hundreds of people to safety, including some trapped on the roofs of trailer homes, in New Jersey communities near New York City that flooded when a tidal surge spawned by Superstorm Sandy overwhelmed a natural berm, Gov. Chris Christie told CNN on Tuesday.
Christie said hundreds more people needed to be rescued in trailer parks in the affected area that included Moonachie, Little Ferry and Carlstadt in Bergen County, about five miles west of upper Manhattan.
No deaths have been reported, Christie said.
Local officials said much of the area was under 5 or 6 feet of water, and rescuers used boats to reach people trapped in their residences.
“We’re in search-and-rescue mode,” said Jeanne Baratta, chief of staff to the Bergen County executive, who added that as many as 1,000 people still need to be rescued.
Baratta said there were some injuries, but no further details were available.
Every street in Moonachie was covered by 5 to 7 feet of water, she said. Earlier, Little Ferry Police Chief Ralph Verdi said 75% of the town was under up to 6 feet of water.
It took 30 minutes for the floodwater to submerge the area sometime after midnight, according to Baratta.
“We had people going up to the second floor of their two-family homes” or on the roofs of trailer homes to be rescued, she said, adding that the three towns “have just been devastated.”
Local authorities are getting help from the state police and National Guard, and rescue workers from Virginia are expected to arrive Tuesday afternoon, Baratta said.
“The rescue workers, they’re phenomenal,” she said. “They’re pulling together.”
