Cohousing-L Mailing List: "emergency plan" for a cohousing community?

[Sophie Glasser (sophiemosaicjoy]

Hello,
Do any cohousing communities have an “emergency plan”? Specifically what to do 
if there is a safety threat to everyone from weather, fire, etc and you need to 
make sure everyone is alerted quickly? e.g. a tornado is suddenly predicted to 
touch down soon and people should go to basements, or there is a nearby fire in 
the woods and people should evacuate, etc. We can certainly have a cell phone 
“group” that could alert everyone at once but what do you have in place for 
people who don’t always look at cell/email or who keep their cell phones off at 
night etc.? Also how do you decide as to when it is truly an “emergency”?
Thanks for sharing what you have in place in your community.
