The ATC-79 (FEMA P-646) report, Guidelines for Design of Structures for Vertical Evacuation from Tsunamis (Second Edition), was initially equally funding by the National Oceanic and Atmospheric Administration (NOAA) and the Federal Emergency Management Agency (FEMA) under the ATC-64 project in 2008. This Second Edition was funded by FEMA under the ATC-79 Project (Published 2012,174 pages).
ABSTRACT: This document provides guidance on the design and construction of structures that could be used as a refuge for vertical evacuation above rising waters associated with tsunami inundation, and includes specific recommendations on loading, configuration, location, operation, and maintenance of such facilities. The report is written to be a resource for engineers, architects, state and local government officials, building officials, community planners, and building owners. In this second edition revisions were made throughout the document, but particularly to the following items:
- Inclusion of observations and lessons learned from the March 11, 2011 Tohoku tsunami;
- Revision and enhancement of the debris impact expression to remove over-conservatism in the prior edition; and
- Updating of all reference documents to the most current version.
