I'm listening to District 15 units now. They are on same talkgroups they were on before but maybe just don't have as much chatter as the other units with whom they share the talkgroups.
District 15 / Loxahatchee - Acreage units are on "NR 2A" (26704) and it's 10-91 car-to-car talkgroup "NR 2B" (26192) which Dist. 15 shares with:
District 2 / Mangonia Park
District 3 / PBSO No. County Unincorp. areas - (Beeline Hwy / Jog Rd station)
District 10 / Lake Park
The Dist. 15 office is temporarily housed at the PBSO Dist. 9 / Royal Palm Beach substation according to the District's webpage:
Palm Beach County Sheriff's Office - District 15 -Loxahatchee/Acreage
PBSO started (and maybe has finished by now) reprogramming it's radios and changing description labels for it's talkgroups to represent some organization changes due to growth. These particular talkgroups are in the "North Road" (NR) set of talkgroups. There are now 4 North Road pairs of groups, 5 South Road pairs groups, and 3 West Road pairs of groups. (Some of those are programmed into the radios for future growth and likely won't see much use for a while.)
See Brian's book, "South Florida Freq. & Trunking Guide" for more info on the Palm Beach County TRS.

Hope that helps.
