Worst case scenario


The beauty of the tall trees and the natural privacy of being surrounded by water are just two reasons that most of us have chosen to live on Marrowstone Island. But these two facts make us uniquely vulnerable to a major event. Fallen trees could damage our homes, block our roads and take down our power and telephone lines. Being an island could partially or totally isolate us from the peninsula and outside services. We could lose the bridge, the causeway, or most of the boats to a major event. Local, State and Federal aid could be unavailable to us for anywhere from days to a month or more.

Regardless of the source of the emergency, it is prudent that we design our Marrowstone Island Emergency Preparedness (EP) plan using ALL of the events described in this worst case scenario below.

What if we just experienced a 9.0 earthquake (Cascadia Subduction Zone) lasting for 2 minutes at 3 AM on the coldest (12 degrees) day of the year with 16 inches of snow and 30 mph winds? It might look like the following ...

 Emergency Preparedness can make all the difference.

Please join your neighbors and other Islanders in this effort by hosting or attending a MYN (Map Your Neighborhood) meeting.

Please get and regularly test an FRS radio (and/or become a HAM), because radio communication will be critical.
