Voytek,
I'm not so sure that it was only a landfill:
Among other waterfront developments in Bayonne Waterfront, Empire Golf USA of New City, N.Y., started construction on a 19-hole, 700-yd. championship golf course seven years ago. The challenging project involved capping and remediating an old city landfill. Bayonne's Doria said the land had been a Standard Oil facility, but John Rockefeller used it to dump the excavated materials from Rockefeller Center in Manhattan during the 1930s.
"It took a lot of work to remediate that land," Doria said.
That brownfields site on a separate peninsula just south of the military base, required Empire to import $7.4 million worth of materials via barge and truck to raise the elevation from 10 ft. to almost 100 ft. above sea level.
