There is an Army Regulation 525-27 Army Emergency Management Program that provides the statutory guidance to the Army on the subject of emergency management. I think if you read it you will find that there isn't that much difference from any other community emergency management program. The National Incident Management System (NIMS) is a major component.
Additionally, you will find that there is a requirement for them to coordinate with their local emergency management counterparts and integrate their planning with the civilian world. It you don't know any of the military leadership in your community a quick phone call and meeting would solve that issue quickly.
