Straight from the RR Wiki:
PINK - One talkgroup, designated PINK is assigned to each city and utilized for common communications between that city's law enforcement, fire service, lifeguard/marine safety and public works departments. Each Pink talkgroup is city specific and unique to that city. Communications can not occur between other cities on the Pink talkgroup. The Pink talkgroup is designated 1C in all fire service radios except Santa Ana, which is 1E. The Fire Authority and Sheriff-Coroner do not have a Pink talkgroup in their radios.
Fire specifically refers to PINK as 1-C.
Other disciplines call it PINK.
City FD's are under their own authority, but dispatched by a regional Dispatch center with the exception of Costa Mesa and Laguna Beach, who have their own Dispatch centers.
IMO, they should stay grouped how they are and just move the zone 1 TG'S to the respective city, since they are city specific. I think if you group everything by city you lose the continuity of the zone concept and it becomes more difficult to dial in a talkgroup.
