The original plan was to have a UHF system.....however a big issue is that FCC is mandating that public safety on 470-512 leave those frequencies. There is not enough spectrum below 470 and not enought for everyone on 700-800, so there is really no place for everyone to move to.
2nd VHF will never leave LA Co for several reasons.
If, and I mean if, the rest of the county goes UHF, the forest service, chp, etc, those angencies probably will not completely switch over. Forest Service, CHP, etc already have there own radio systems.
Case in point. If you look at Federal Fire Ventura. They are now on a trunked UHF radio system, however the rest of Ventura Co is on VHF.
Also per FIRESCOPE, VHF is the standard for wild land fires regards of what individual agencies, cities or counties are currently using. So VHF has to stay.
Camp Pendleton will transport LACoFD units to the island during a major brush fire. That would be outside the city limits and therefore under the control of LACoFD. AFD during such an incident would be support to LACoFD and would operate on LACoFD frequencies which are already programmed into their radios.
I worked the island for 3 years and would ocasionally work as dispatcher. On a side note AFD only staffs 2 firefighters and one captain at a time. A major portion of the department is paid call firefighters. On a hill near the middle of town there is an old air raid siren. 1 long blast of the siren indicates a working fire inside the city limits, 2 shorter blasts indicate a fire on the water.

This document says that some of the LA County repeaters at 152 Mhz are simulcast and some are steered

Last I heard they are all Vote Steering Tx. Last I also heard these channels were not completely functional yet.
After I read message #36 up above, I have spent some time listening only to CHP and following the CHP CAD right along with it. I have to admit that the CAD and their activity on the radio are in sync as far as the CAD goes, but it falls way short of listing all the calls and incidents they are doing. At 3 AM on a Sunday a lot of them are probably at jails all around the county booking drunk drivers, but none of them show up on the CAD, as was explained.

From the CHP PIO's mouth
While she could not give me a precise number, both for policy reasons and because it varies by day, shift, season, etc, the "rule of thumb" for L.A. County's offices averages about 20 patrol (cars and motors) units per office per shift. That is ~200 officers on days and evenings, and since they double up on graveyard shift, approximately 400 officers on duty in L.A. County on the midnight shift.
She explained that the L.A. Central Office #15 can easily have double that average number, or 40+ units during busy periods, while some outlying offices may have fewer units, and again emphasized that the numbers will vary somewhat depending on day of the week and other factors.
We talked briefly about the CAD and she confirmed that the "public" version of it is severely abbreviated, and only vaguely representative of just their highest-visibility activities.
OK, you can choose to believe this or not to believe it, neither of which will have any effect on reality. I just got off the phone with the Public Information Officer for CHP Southern Division (the Los Angeles County offices) in Glendale.

Even to me, 400 officers in 200 cars seems like an awful lot of cops just for the L.A. freeways 3 or 4 AM, even on a weekend.

Remember that they are talking about over 500 miles of freeways in the almost 5000 sq mile COUNTY, and all surface streets in unincorporated county areas. A single DUI traffic accident with a fatality or serious injuries can easily tie up a half dozen or more CHP units - often many more depending of the number of vehicles involved and other things (big-rig? fire? hazmat?) - for hours, with immediate response, traffic control, on-scene investigation, awaiting the coroner if needed, follow-ups to hospitals, booking the suspect(s) and writing up all the required reports.
It's not at all unusual for a serious accident halfway into officers' shifts to make them unavailable for the rest of the night and then often working long past their scheduled end-of-watch time. Multiply that by a dozen more injury crashes, even more non-injury collisions, add a bunch non-accident DUI arrests and bookings, and it's not hard to imagine them coming close to using up most all of those cars that started out their shift as "available for calls."
They don't just drive up, scratch out a quick report and then go back available for the next one.

You're right about that. And Ponch ended up hawking lush, luxuriant land in places like beautiful Modoc County:
