Introduction
This manual presents methods and procedures for use by city
civil defense organizations in preparing a civil defense urban
analysis. An urban analysis is the process of collecting, presenting,
analyzing, and utilizing pertinent information about urban
areas. Since the primary purpose of a civil defense urban
analysis is to provide the tools for undertaking realistic civil
defense planning, all pertinent aspects of the city must be
considered.
Assembling data and presenting the information graphically
on maps is only the first step in an urban analysis. The area in
which an exploded A-bomb can cause maximum casualties and
physical damage must be located. Then a hypothetical attack
must be assumed and the damage assessed. From this is determined
not only the potential casualties but also the potential
damage to each urban feature. Next, the physical area of the
city must be organized for operations and operational plans
developed by the civil defense services. In this manner, the
urban analysis can be of practical use rather than as mere
reference material to be looked at occasionally before the attack
or to be referred to after the attack.
The methods and procedures presented here are suggested
ones only. Alternate improved methods may be worked out in
some instances. Maximum utilization should be made of available
maps and data in municipal and other public offices and
agencies as well as those in private institutions.
