An excellent guide - thanks for the pointer! (people following the link above will need to remove the full stop from the URL)
Another v-good guide for developing Disaster Plans is available
here (designed for libraries but with concepts common to NPO's)
These guides are very useful if you want to start your planning process 'from scratch', rather than using a template. Personally I prefer this approach because it assists understanding and helps to educate us in the concepts of disaster planning,
Dmyers have you used the NYC guide to develop a disaster plan? – If you have, would you share it here?
