NTHMP - Tsunami Evacuation Signage

Tsunami Evacuation Signs

The purpose of this page is to share signage artwork and wayfinding guidance. A brief document about the history of the NTHMP's adopted evacuation signage and usage guidance is in development. Be aware, while most states and territories use similar graphics, they are not always interchangeable. Before printing and installing signs, unless otherwise noted below, interested parties should contact their state department of transportation for additional information about state and Federal Highway Administration requirements. For the U.S. territories, interested parties should contact their NTHMP emergency management member.

Alaska

In consultation with the Alaska Department of Transportation and Public Facilities, the Alaska Division of Homeland Security and Emergency Management has adopted standardized signs and associated procedures for use in tsunami-prone areas. Communities and land managers interested in obtaining signs should contact the Alaska State Hazard Mitigation Officer for information about the procedures. Artwork is not currently available for download.

California

California Tsunami Program partners utilize the full suite of available tsunami signs (EM-1A, EM-1B, EM-1C, EM-1D, and EM-1E) throughout local coastal jurisdictions. The California Department of Transportation has adopted the Federal Highway Administration’s policy as described in the Manual on Uniform Traffic Control Devices, Section 2N.03 for evacuation route signs, using EM-1 and EM-1a signs along state highway transportation corridors.

Florida

The State of Florida has not adopted statewide tsunami signage or procedures. An example of the signage developed by and implemented in Santa Rosa County is below. Artwork is not currently available for download.
