The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2006.

Read together — 73% permit, 61 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.

73% of every record here performs the same act: permit.
