County hears CRIS radio coverage map; state compromises on 'all‑call' function
Summary
Mono County staff reported progress on the statewide CRIS public‑safety radio migration, a negotiated limit on all‑call talk‑out sites, and a predictive coverage map showing improved but imperfect countywide mobile coverage once remaining sites come online.
County communications staff on Jan. 13 reported steps forward on the statewide California Radio Interoperable System (CRIS) and showed a predictive coverage map for Mono County.
Kirk (county communications) said the county had secured a compromise with Cal OES that removed three fringe sites (Leviathan, Silver and Lincoln) from the CRIS "all‑call" list to limit load on the system; that change has already been implemented. He said the county will revisit loading and coverage once subscriber activity increases.
Kirk also previewed predicted coverage improvements from several new sites, and explained that Antelope Valley Fire Department and Antelope Mountain sites will be critical to filling gaps along Highway 120 East and other corridors. He noted that predictive models show good outdoor mobile coverage in many communities but still contain holes that will require drive‑testing, relay points or alternate workarounds.
Supervisor Dugan and others pressed staff to continue negotiating with Cal OES to improve coverage on critical highway segments; IT Director Mike Martinez said county staff will continue advocacy to enhance build‑out.
This was an information item; no board action was required.
