Why Pre-Planning Evacuation Routes Matters

When an evacuation order is issued, roads fill quickly, GPS signals get overwhelmed, and stress makes clear thinking harder. The households that move safely and efficiently are those that already know where they're going — before the emergency begins. Planning your routes in advance takes a few hours and could be the most valuable time you ever spend.

Understand the Types of Evacuation Scenarios

Different emergencies call for different responses. Before mapping your routes, consider which scenarios are realistic for your area:

  • Wildfire: Fast-moving; you may have minutes. Routes must be pre-determined and practiced.
  • Flooding: May cut off roads progressively; high ground routes are essential.
  • Hurricane: Typically offers more warning; contraflow may be in effect on highways.
  • Hazmat incident: May require you to move perpendicular to the wind away from the source.
  • Civil emergency: May require avoiding major roads and using secondary streets.

Step 1: Identify Your Starting Points

Think about where you and your family members are during a typical day:

  • Home
  • Workplace
  • Children's schools
  • Frequently visited locations

You need at least a basic route plan from each of these locations, not just from home.

Step 2: Map Primary and Alternate Routes

For each starting point, identify:

  1. Primary route: Your fastest, most direct path to safety under normal conditions.
  2. Secondary route: An alternate path if your primary is blocked, flooded, or congested.
  3. Tertiary route: A third option, ideally using entirely different roads.

Use printed maps — not just your phone. Download offline maps to your device as a backup, but always carry a physical copy in your go-bag.

Step 3: Know the Hazards Along Each Route

Drive each route during normal conditions and note potential choke points:

  • Low-lying underpasses that flood easily
  • Single-lane bridges that back up
  • Railroad crossings that may be blocked
  • Areas near industrial facilities (toxic risk in certain emergencies)
  • Roads that pass through wildfire-prone corridors

Step 4: Identify Destinations Along the Way

Your evacuation plan isn't complete without knowing where you're going. Identify:

  • Designated public shelters: Contact your local emergency management office or check Ready.gov to identify official shelters in your area.
  • Friends or family outside the risk zone: Confirm in advance that they can accommodate you.
  • Pet-friendly shelters or hotels: Many public shelters don't accept pets — have a backup plan.
  • Fuel stops: Know where gas stations are along your routes and keep your tank above half when threats are elevated.

Step 5: Establish a "Go Threshold"

One of the most dangerous habits is waiting for an official order before starting to move. Decide in advance under what conditions you will evacuate without being told to:

  • "If fire is spotted within 10 miles of our neighborhood, we leave immediately."
  • "If water is rising on our street, we do not wait."
  • "If a mandatory order is issued for any adjacent zone, we go."

Early evacuees face far less traffic, have more fuel options, and reach safety faster. Delaying is statistically more dangerous.

Shelter-in-Place vs. Evacuation

Not every emergency calls for evacuation. Certain events — a nearby chemical spill, severe outdoor air quality, or an active threat — may require you to shelter in place instead. Know the difference:

Scenario Recommended Action
Wildfire approaching Evacuate early
Tornado warning Shelter in place (interior room, lowest floor)
Nearby hazmat release Shelter in place (seal doors/windows)
Hurricane (Category 3+) Evacuate if in coastal/flood zone
Power outage (extended) Evaluate — may need to relocate for warmth

Practice Makes the Difference

At least once a year, run a household evacuation drill. Drive your primary route. Time it. Identify any bottlenecks. Walk the alternate route on foot if relevant. Include your children so they understand the plan. Muscle memory and familiarity reduce panic and improve outcomes when the real thing happens.
