We use technology to guide drivers with updates on weather, pavement temperatures and traffic conditions. Many of our vehicles and our vendor partner vehicles are outfitted with "green" technology that helps us conserve one of the most costly elements of winter storm operations - road salt. Our GPS-enabled closed loop salt metering systems provide more precise application of salt while giving us location and time information so we know which roads were treated and when.
Depending on the type of storm and pavement temperatures, we may choose to pretreat the roadways. This involves the application of a salt brine, which dries quickly after application and leaves a layer of salt on the pavement. When the storm begins, the snow melts on contact and prevents it from compacting and bonding to the pavement. This allows us to clear more with each pass of the plow and to make final clean up easier after the storm is over. Lower salt usage also means less salt flowing into nearby waterways.
If we have a large storm or blizzard, or a series of accumulating storms, site lines may be reduced at intersections, driveways and parking lot entrances due to high snowbanks. On occasion we may push back snow piles or cut them back - a process called "shelving" - to make room for snow from future storms. This process may deposit additional snow on driveways, walkways and sidewalks. We ask for your continued patience as we work to keep roads as clear as possible.
