And the reason they didn't? Money.
By sharing a dispatcher with Midvale, it reduces the cost for both Midvale and Cottonwood Heights.
Each agency that has it's own channel requires more overhead, as you have to add another dispatcher to the system. When you have to staff that position 24 hours a day 7 days a week, it's not cheap.
The 2006/2007 fiscal numbers for VECC charges show a rather significant impact. Draper was paying $122,000 to VECC (34 sworn officers). Midvale (approximately 50 officers) was paying $209,000, Murray with approximately 45 officers was paying $284,000. West Valley, the largest department outside of SL County Sheriff and SLCPD was paying $672,000 with upwards of 90 patrol officers.
The call volume data shows that Murray accounted for 5% of the workload, Midvale 8%, Draper 6%, WVC 24%.
By not having a seperate channel for Midvale and Cottonwood Heights, the overhead is reduced, and their share is likely reduced, and the service doesn't suffer.
