Typical Snow Event: During a typical winter weather event after arterial streets, transit routes, and school area streets (if school is in session) are cleared, the City deploys one plow truck to each of six snow removal zones, which allows crews to simultaneously remove snow throughout Coralville. Snow is removed from cul-de-sacs with end-loaders. The City’s six zones are roughly defined by Interstate 80, Coral Ridge Avenue, 12th Avenue, and 1st Avenue.
Severe Snowstorm: During a major winter storm, such as a blizzard, after the snow has stopped falling and the arterial streets, transit routes, and school area streets (if school is in session) have been cleared, Streets Department crews clean residential streets and cul-de-sacs by deploying four plow trucks and two end loaders to one zone at a time. Under this system, all of the operators work together in a zone to improve efficiency, completing a zone prior to moving onto another zone.
After all six zones are cleared, crews begin to push snow back further from curbs and haul snow from intersections as necessary. The zone where crews begin is determined primarily by the time of day when this system is initiated since some factors, such as tree coverage and available light, can be leveraged to maximize efficiency.
