The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2014.

Read together — 45% violation, 60 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$3.4M of Kings, written across 445 government filings.
