Major disaster comes with an expectation that all the Portland Fire Bureau rescuers will quickly be fully tied up. Not my expectation, but what the pros believe. So, the city Office of Emergency Management recruits and trains Neighborhood Emergency Teams, modeled on the Community Emergency Response Teams.
How many NETs are there? Portland's 545,000 people have 851 volunteers to save them. Do the math.
This map of Portland Fire Stations shows how many Neighborhood Emergency Team members there are for each station. The first number in the oval shows how many fully trained members there were at one time (not currently verified) and the second number shows how many candidate members started, but have not completed the training.
