Henrico is covered by three radio "channels", West, North and South. HPD is divided between West/North/South. West and North Police units operated from the HQ building on Parham Road. South units operated from the district station near the airport.
West is the west part of county to the RR tracks that parallel Staples Mill Road
Central is from the RR Tracks the parallel Staples Mill Road, to roughly the Richmond Nascar Track
South is from the Richmond Nascar Track to the eastern end of the county.
There are roughly 9 zones in the county........with smaller beats inside each zone. 100 series cars are midnight shift, 200 series cars are day shift, 300 series cars are evening shift. It gets way more complicated from there according to a guy who works there......Sgts, Lts, special units, K9, traffic, motorcycles etc....
