Why there is no map on this page

There are more than three thousand counties and county-equivalents in the United States, plus independent cities, and tribal nations, and towns that run their own emergency management. A storefront that published a guessed URL for each of them would be a rumor mill with a search box. We will not do that. Place-aware lookup can come later, when it is a real lookup. Today is a twenty-minute ritual you run yourself, because the person who finds the office is the person who will remember it exists.

Write the answers on paper. The cabinet door that already holds three neighbor numbers can hold four more lines.

Minute 0–5: the office

Open a browser. Search the name of your county (or city, if you are in an independent city) plus the words "emergency management." You want the official site: a .gov, a county domain, a page that lists a director or a 24-hour number that is not 911. Bookmark it. Then write the URL in ink. Phones die. Bookmarks vanish when the account does. Ink on a cabinet door has never once asked for a password.

If the first result is a Facebook page, keep looking. If the first result is a vendor selling NOAA radios, you used the wrong words. If you cannot find anything, call the non-emergency number on the sheriff or fire department site and ask "who is emergency management for this county?" That sentence is allowed. You are not wasting their time. You are the civilian they wish would call on a quiet Tuesday.

Minute 5–10: alerts

Wireless Emergency Alerts — the presidential / imminent-threat / AMBER messages — already reach most phones unless someone turned them off. Check that they are on. Then find the local system. Counties brand these differently: reverse-911, CodeRED, Nixle, AlertSense, a city app with a pine tree on it. The Ready.gov alerts page explains the national layer. The local layer is on the OEM site you just found, usually under "alerts" or "notifications" or "sign up."

Sign up. Use a number that will be in the house if you are not. If they offer email plus SMS, take both. Then, because this is Terrarium and we do not trust a single channel: add the OEM's after-hours number to the paper list. Alerts are a gift. They are not a plan.

Minute 10–15: 2-1-1

2-1-1 is the quieter number. Housing, food, disaster recovery, "my mother needs a ride to dialysis and the roads are ice." It is not 911. It is the number that exists so 911 can stay 911. Dial it once on a calm day so you know what the prompt sounds like. Write "211" under the OEM URL. Visit 211.org if you want the web locator instead of the phone.

This is also the moment to notice whether your county lists a CERT class calendar. Community Emergency Response Team training is local. The national door is ready.gov/cert. The class is whoever your OEM or fire department is running this quarter. If there is a date, put it on the household calendar the way you would put a dentist. If there is not, you still have the free ICS-100 course online, which is vocabulary, not a helmet.

Minute 15–20: tell someone

The ritual is not finished until a second household knows you did it. Text one of your three: "I found the county emergency management page and signed up for alerts. URL is on the cabinet." That is the entire message. You have just made the information a street fact instead of a private bookmark.

Optional, if you still have coffee: print the OEM homepage, or at least the alerts page, and put it in the same folder as the household plan. Ready.gov/plan is the national template for that plan. Fill the contacts with the numbers you just wrote down. A plan that only lives in a tab you opened once is a wish.

What you now have

An office. An alert path. 2-1-1. A CERT calendar or an honest blank. Paper. One neighbor who knows. That is the municipal handshake from the civilian side: not a seat in the EOC, not a claim that Terrarium is part of the official system, just the ability to find the people whose actual job is day three. The first 72 hours are still soup and names. After that, it helps if you can spell the county's name the way they spell it on the door.
