EVACUATION MAP BROCHURE:

•  

The area in yellow is a worst-case evacuation area for a locally generated tsunami.

The brochure gives lots of other useful information about preparedness and is downloadable as a PDF file from the website above. Map base is a street grid.

•  

This is a scientific product based on detailed computer modeling of 3 Cascadia subduction zone earthquakes, least, middle, and worst case events. These maps are not downloadable. Map base is either an orthophoto or a street grid.
These maps include: IMS-2, 3, 11, 12, 13, 21, 22 , & GMS-99.

A regulatory map, or Senate Bill 379 map, of the "official" inundation zone that limits new construction of certain critical and essential facilities, including some schools

•  

Inundation lines on these maps can be viewed as sort of a middle case event and were produced in 1995 to implement Senate Bill 379. These regulations are summarized in the attachment. No other map can substitute for an SB 379 map, even if the map is based on newer data, until an official DOGAMI Board action approves the new map. These maps are downloadable from the website above and appear on a USGS topographic map base.
These maps include: O-95-09 to 37, O-95-43 to 66, O-97-31 & 32. They are also available on CD-ROM in .pdf format as O-00-05
