There was a firefighter convention in Wildwood, 90 miles south, at the time, so roughly 400 firefighters from 30 towns -- many of them volunteer units -- responded, Seaside Heights Mayor Bill Akers said Friday.
Had they not been nearby, the damage could have extended beyond six blocks of boardwalk in Seaside Park and two blocks in Seaside Heights, he said, estimating that reconstruction costs will reach the millions.
The Seaside Heights boardwalk was in the public eye shortly after Superstorm Sandy blew its famous Jet Star roller coaster into the water last year. The coaster was removed from the ocean in May, shortly before the boardwalk reopened for business.
Town officials plan to meet with business owners and help them rebuild, said Seaside Park Town Administrator Robert Martucci.
Akers added that the town will also assess the damage.
"If there's a silver lining, we just built it. We have the specs. We know what we're doing," the mayor said. "We'll get it back up."
