The 2013 Rim Fire as it progressed towards Tuolumne was one of the first "evacuate an entire community and population center" incidents since the advent of the VTAC/UTAC/8TAC series. At the time, it had become the single largest Law Enforcement mutual aid event in the history of the California Law Enforcement Mutual Aid System. The fire rapidly picked up some of those VTAC's early in the game. Luckily a pair were left that we could make a VTAC36 repeater out of and provide a resemblance of coverage for law enforcement in the fire area. But it didn't address the hundreds of officers coming in from Sacramento PD, Oakland PD, Alameda SO, Tulare SO, Fresno SO, Stanislaus, etc. They were provided handheld radios on the VTAC36 repeater and told good luck, and were sent out to patrol and protect from looters, and standby for further evacs of thousands. Handheld radio coverage, in a patrol car, in the mountains.
Their patrol radios were useless for two reasons, they weren't programmed with interop freqs (because of lack of effective comm coordination that
still exists today), and many were UHF and 800Mhz. We needed a second repeater for the next round of evacuating the entire Hwy108 corridor, and there was nothing left. I was one of a few in the bullpen that suddenly became adhoc freq coordinators looking for scraps. CESRS2? CALAW2? Etc. Etc. All were used or would be serious ask-for-forgiveness-later if we threw it into a repeater pair. Ended up using a privately licensed frequency in the area that gave use permission, and tied it into a freq that Tuolumne SO had, made the pair, programmed the repeater, and we had something. And it still would have required programming every handheld radio with that pair for every officer before going into the field. Life Safety. Thankfully the fire stopped before that repeater had much air time.
2017 Napa complex. Same problem. 2018 Oroville Dam response and then later that year the Carr and Camp Fires were a little better, but limped through the whole thing. Butte County and some surrounding counties have some solid communications skillsets and sort of made things work, despite unnecessary politics still getting in the way. They also were adamant that 2018 problems never happen again. Queue up 2020 and the Bear Fire last month. Now there is an interop stack on a mountain top that happened to cover 100% of the fire, and most incoming agencies from hundreds of miles away, regardless of radio band, could plug right into their VTAC, UTAC, 7TAC or 8TAC channel on their patrol car radio, and talk to every other officer, and the Butte SO Dispatcher. Their radios, just, worked. Those that showed up STILL without interop freqs in their radios were issued a handheld and told good luck; in 2020, where most $8000 radios with 5000 channels and 100 zones are only programmed with 1 zone and PD1, PD2, PD3, and CLEMARS.
You can't count on effective communication coordination on the back end, so as a citizen, check with your local law enforcement and ask them if they have interop channels programmed in their radios
and if they know how to get to them. If not, raise some noise. Letters to the Editor. City Council Mtg public statements. What if your community is next? Officers coming to help won't be able to effectively talk and be safe. They will be hindered evacuating you, and they will be hindered in protecting your home afterward from looters, and they will be hindered in protecting themselves and calling for backup while dealing with criminals in a disaster area.
All that, ALL THAT, because a state frequency coordinator issued VTACS to a fire, instead of probably reeeally stretching the available fire tactical frequencies at their disposal. We're almost there. We saw it work flawlessly in Butte in 2020, and had to fight still as fire almost grabbed one of the VTACS being used. We have proven plans in place now to rapidly deploy a solution anywhere in the state in 2 hours, (or 5 minutes with the flick of a switch by the county comm tech). All of that can be ripped away if we lose all 4 VTACS in an area to the fire line.
