DUmmies, remember, this is for an unincorporated area. They are technically not part of the city that pays the taxes for fire protection, and the city cannot raise their taxes. The fire department decided that since these people weren't paying taxes to help support the fire station, they would be charged a separate fee. We are looking at about $6.25 a month for assistance in the case of fire, far less than any other insurance I can think of.
If the people in the unincorporated area don't want to pay the fee, they should try organizing a volunteer fire department and covering all the costs related to that.
