I can not speak for Deland but when the county took over dispatching for all the cities except for Daytona Beach nearly everything is done on Sheriff talkgroups.
When I listen to Ormond, Port Orange, South Daytona, and the Shores you'll hear some comms on the their tac or old talkgroups but not often.
Daytona Beach PD still uses their tac/narc talkgroups everyday. Since they do their own dispatching the Daytona talkgroups haven't changed.
The real bummer is Daytona Beach Fire. They are dispatched on a county talkgroup so if you want to listen for Daytona Beach fire you have to listen to dispatches for many different cities. RR's database is outdated as I haven't hear anything on any of the Daytona Beach Fire tg's in years. Don't bother programming in the 11-04x groups because they have been dead for years. RR's database should be updated or at least a notation regarding this made. I mentioned this sometime ago but its still listing 11-04x as active groups.
