The Streets & Stormwater Dept. handles snow and ice response for the City of Tulsa.
The first focus for the department is to clear city arterial streets for emergency responders. After arterial streets are clear, the second focus then moves to residential or collector streets near hospitals, schools and areas with steep hills.
After the arterial streets were cleared and drivable, crews began treating residential and collector streets on Saturday from 12 p.m. – 12 a.m.
Crews worked on secondary and residential streets for nearly 12 hours, applying a salt and sand mixture to the roads. The sand mixture helps create traction for vehicles and this type of mixture is more effective in low-traffic areas. The city only uses salt to treat arterial streets.
Crews treat most secondary and residential streets because they feed directly into schools and these areas have bus routes. Many factors go in to school closings including not only street conditions, but extremely cold weather.
Snow and ice crews are assigned to 35 specific routes totaling 1,768 lane-miles. During the storm, crews used 5,358 tons of salt, plowed 12,000 arterial lane miles and treated 18,000 miles of arterial and collector streets. The Streets & Stormwater Dept. is no longer on 24-hour operations, but treating streets and areas with steep hills when needed.
During wintry weather, snow and ice crews follow specific routes on arterial and collector streets. The following link includes every map and route the City uses for arterial streets, collector streets, schools and steep hills: https://www.cityoftulsa.org/media/150900/pw%20maps.pdf
