Two real NYC sites, from reports on public file.
118 Hope St, Williamsburg
15 ft of fill over soft organic soil, water at 10 ft. Piles were recommended. Dozens of nearby boring records already showed it.
1454 39th St, Borough Park
Dense glacial soil, water at 45 ft. A 24-ft cellar stays above the water. Good news is worth knowing too.
