The NYTimes featured an article today titled How to Prepare Your Community for a Disaster. This article focuses on personal and community preparedness. Generally the advice is good although many of the steps and info sources listed can readily be found as part of the Community Emergency Response Team (CERT) training and manual. That source is not noted until the list of references at the end of the article.
Mitch Stripling has also written a useful handbook for emergency management practitioners: Managing Chaos.
