The locations shown are the library (tallest building on campus I think) and Pardall road which is the location the Isla Vista foot patrol office. The University police are "state police." Frequencies licensed to them could also show in the FCC records as State of California. Usually they are licensed to the Regents of the University of California, however. The sheriff also has 460.175 as a tactical repeater in Isla Vista and has no licenses on 460.250. None of this really means anything because the sheriff could operate on 460.250 and the CHP could use 460.175. Anyway, I've have never heard these used. Things have been quiet in IV of late. During the riots in the late 60's the sheriff was still on low band as were the university police and the CHP of course.
The control point listed on the license is the CHP office in Ventura.
The UC system has it's own police force. Some of the original radio system licenses are still held by CalOES and UCPD is operating under those. Most/All of the recent licenses (last 25 years at least) are all under the Regents of the University of California, and UCOP is pretty adamant about keeping it all under that name. The original license grant was in 2000, which makes it likely that this was (at least originally) someone else other than UCSB.
I used to know the radio guy at UCSB, but he retired. He would have known. May have started out as CHP and been given to UCSB, but I'd be surprised if UCPD at the Santa Barbara campus would be using anything other than their own trunked system. While some campus departments choose to go with their own radios, larger parts of the campus, especially public safety, stay on the larger trunked system for interoperability with other campus groups.
More than likely, this is CHP or some other state agency using the existing library radio site to get the coverage they wanted for a specific application. Would be interesting to know if it's CHP, or one of the agencies they have an agreement to dispatch for.
