Why it works

The link is the address

No database and no lookup table. The id decodes straight to the district, so there is nothing to expire.

The right jurisdiction

Keyed to the government whose ordinance zones the land: the city inside city limits, the township where townships zone, the county everywhere else.

Readable and URL-safe

The zone code appears as written. Characters a URL can't carry are percent-encoded, so R-10/5 becomes R-10%2F5.
