The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2019.

Read together — 43% permit, 39 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$6.8M of Kings, written across 364 government filings.
