Right now, any Uhland calls for police service on the Caldwell County side are transferred to Hays County Dispatch. I believe that Uhland PD is happy with this arrangement, and is eager to maintain interoperability with HCSO.
If they grow enough to set up a 911 Dispatch and associated talk group, I believe they will want to stay affiliated to hear the HCSO talk groups. However, with Austin/Travis County responsible to dispatching fire resources for Uhland and Hays County dispatching EMS through Kyle Fire Dispatch or Caldwell dispatching EMS from their new ESD 5, I think it will be a long time before anything like that happens.
