The map below shows each group of residential snow plow sections. There are 24 residential routes, and 4 sections in each route. We begin in "A" in each route, and systematically work our way through to the "D" section. In all, there are 96 sections that must be cleared. Our admin team works around the clock at the City Yards and communicates with the contractor admin team at their office.
This map shows how our process actually works. We deploy plows in all parts of the city simultaneously, and in theory, everything wraps up at approximately the same time. Obviously there are variables that must be taken into account - amount of snowfall, hills, cars parked improperly, etc., but overall this method has proven to be very effective.
