Has the city or state earned "green status" from the Centers for Disease Control and Prevention? Suppose that in the midst of a flu pandemic or bio terror attack, your city ran low on critical medicines. The CDC stands ready to help by distributing drugs and medical equipment from its Strategic National Stockpile. But the agency wants to know that a city or state is able to quickly mobilize hundreds of health workers and volunteers trained to handle the logistics, and has space set aside for storage and refrigeration. You're best off if your city has earned the CDC's "green status"—even if the state itself has not—because it means local health teams can handle the supplies on their own.

　　Does the city website explain clearly what to do in case of evacuation? Who can forget the images of stranded New Orleans residents, or the 5-mph crawl out of Houston? It turned out that New Orleans's evacuation plans were both inadequate and poorly communicated. One way cities can avoid a similar nightmare is to put clear and easy-to-find evacuation information on their websites. Some cities, such as Boston and Washington, post the preferred street routes. Others, like Las Vegas, won't disclose details due to security fears, but their websites may provide ways to quickly get evacuation details when you need them (such as numbers to call or alert services you can sign up for). Among the more important things to address are people without vehicles of their own (a huge failing in New Orleans) and instructions for pet owners.

　　Does the website include details for residents with special needs? In July 1995, a vicious heat wave killed nearly 500 people in Chicago; a disproportionate number of them were older residents who lived alone. In any crisis, the elderly and disabled can be uniquely vulnerable. That's why cities such as Houston are creating registries of residents who would need special help. Such lists would indicate, for instance, that a certain person in a certain apartment building is wheel-chair-bound. Other cities are instructing people with disabilities to call 911 for assistance—though this relies on phone systems that could be overloaded or go dead. If a city's disaster planning shows no awareness of special-needs people, it isn't complete.
