Staten Island holds 2% of everything on record but 11% of foundation filings — more than 5 times the citywide rate.

Foundation work appears on new buildings and on underpinning beneath existing ones, and a single job can carry both, so this is a count of filings rather than of sites. The catalog is a rolling window over recent Department of Buildings activity rather than the city’s whole history, which is why the figures above are given as shares — a share survives the window, a count does not.
