Amador El Dorado Unit, just like many others, works extensively with local fire protection districts, who all have their own staff, assignments, and bureaucracy.
I am not familiar with the others, but just the El Dorado Side of the AEU interoperates with, and dispatches for, the following agencies:
- CalFire (obviously)
- El Dorado County Fire Protection District
- Diamond Springs - El Dorado Fire Protection District
- Mosquito Fire Protection District
- Georgetown Fire Protection District
- Latrobe Fire Protection District
- Pioneer Fire Protection District
- Rescue Fire Protection District
- Garden Valley Fire Protection District
- Cameron Park Fire Department (staffed by CalFire personnel)
- El Dorado Hills County Water District
Keep in mind while they are all dispatched on one channel, they are separate agencies. So you will have to check the website of each district for more info.
Below is a map of El Dorado County's Fire Protection Providers (Eastern El Dorado county uses channels and Dispatch centers seperate from Western for all Public Safety ops)
