The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2012.

Read together — 43% permit, 31 years of accumulation, a parcel of New York — these scattered records compose a portrait of the address that no single page sets out to draw.

$8.8M of New York, written across 280 government filings.
