Agencies move around, but this is a new one to me.
Where to put the emergency management function? That question is asked a great deal. Not that long ago, a debate raged about having the Federal Emergency Management Agency (FEMA) pulled out of the Department of Homeland Security (DHS). I haven't heard that argued for some time.
State agencies get swapped around between state agencies on a fairly regular basis. Twenty-three years ago, about half the states had emergency management associated with their National Guard. I heard that that number has decreased some from that high point. In Michigan, emergency management is still part of the State Patrol/Police. Texas' was once part of the Texas State Police. New Jersey's is part of the State Police. The location in government that I prefer emergency management to be in a state is directly under the governor of the state.
Washington state and Florida were once both under Community Development departments. I didn't like that at the time due to leadership issues, but organizationally, and when you think about disaster mitigation, it is not a bad place to put the function.
Today, I heard a new one. The Texas Division of Emergency Management is now part of the Texas A&M University system. OK — somehow that works for Texas. They are a little bit different, or shall I say "exceptional" down in the heart of Texas.
