Find your evacuation zone before you need it

An evacuation order names a zone, not a street or a town. When a Sheriff’s Office issues one, it points to a zone code drawn on a map ahead of time — and if that code is unfamiliar, the middle of an incident is the wrong moment to work out whether it means you. It costs nothing to know it early.

What a zone is

An evacuation zone is a geographic boundary drawn in advance by local emergency officials, not improvised during an incident. Calaveras County’s Office of Emergency Services and Sheriff’s Office maintain zones through Genasys Protect (formerly Zonehaven), the same public lookup tool used by dozens of California counties. Enter an address at protect.genasys.com and it returns a zone ID, plus that zone’s current status. Calaveras County’s guidance on what to do with that ID is blunt: write it down somewhere visible, “like on your refrigerator” — it is the name that will show up in an alert, not the street.

Warning and order are not the same word

Cal OES defines exactly two evacuation statuses, and the difference is about time, not severity:

• An evacuation warning means a potential threat exists. It is the signal to get ready — pack, arrange for pets and livestock, account for anyone who needs more time to leave — because an order may follow.
• An evacuation order means an immediate threat. It is a lawful directive to leave, and the area is closed to public access.

The Tuolumne County Sheriff’s Office uses the identical two-tier language, word for word. This is statewide terminology, not a Calaveras-specific system, which is why the same two words apply on both sides of the corridor even where the local zone tools differ.

Where the authority lives

S.I.E.R.R.A does not draw these zones or decide when a warning becomes an order — Sheriffs’ offices and Cal OES do, and only they can issue or lift one. The Live Feed points to Genasys for evacuation status for the same reason: the authoritative record belongs with the agency that issues it, not with anything that mirrors it. When an order comes, it comes from them, and it is the one to act on.

Looking up your zone at Genasys Protect takes under a minute. Doing it now, rather than during the next red flag day, is the entire reason a zone system gets drawn years ahead of the fire it is built for.
