Hennepin County is Unique.
The Hennepin County Sheriffs Office Communications center, aka The Tower, does have its own dispatch talkgroup, btu there are many other PSAPs in Hennepin County and each of those have their own dispatch talkgroups.
There are unique fire dispatch talkgroups for
Minneapolis
Richfield
Bloomington
Edina
Golden Valley (Dispatched by Edina, but on their own TG)
St. Louis Park
Minnetonka
Eden Prairie
Hopkins
MSP Airport
St. Paul Fire (Covers the VA Medical Center in Minneapolis and Fort Snelling).
Anoka County has one dispatch TG for Fire, Washington, Scott and Dakota each have 2, but they are commonly patched. Ramsey County has 2 Dispatch Talkgroups, Plus St. Paul has their own dispatch talkgroup and White Bear Lake Maintained their own PSAP.
Hennepin County was the first county to migrate to ARMER and as such they beat alot of the federal mandates that have applied to other counties. Essentially the federal government wont give a city entity nearly as much grant monies if they are not part of a consolidated PSAP. Ramsey County had, i think 4 additional PSAPs prior to their migration to ARMER, but those PSAPs consolidated during the Move. White Bear Lake felt that they could provide better services to their citizens in a center that is local, so they took a tremendous hit in grant money andI can only assume passed it on to their consumers.
By this summer, i believe, the State Patrol will consolidate from 12 dispatch centers to 3 (Waters Edge RTMC, Duluth and Rochester) as they migrate all of their operations to ARMER.
Most everyone (who actually gives a hoot about this stuff) has their own opinion on PSAP consolidation, I am personally a fan of it as it allow agencies to receive better, more standardized dispatch services at a lower cost to taxpayers.
3016 is the Mpsl FIre Dispatch Talkgroup. There is a TGID in the 10xxx's that was used during the inital rollout of the system, but is inactive now.
