By the numbers: Eastern Iowans prepare for heavy snow, blizzard
Blizzard conditions could develop Thursday
Crews scurried Wednesday to make final preparations for the up to 12 or more inches of snow forecast for Eastern Iowa through tonight.
Here’s a look at some of the resources that will be used.
- Equipment: 96 vehicles with plows, including dump trucks, pickups, graders, end loaders and tractors; 36 of the vehicles have spreaders
- Crew: 100-plus employees from three departments
- Salt/sand on hand: 5,000 tons of salt; 1,000 tons of sand; 1,000 tons of salt/sand mix
- Miles of streets: 620-plus miles or 1,600 lane miles*
- Timing/strategy: 10,000 gallons of salt brine (10 tons of salt in the mix) applied pre-storm; plowing/spreading begins immediately in big storm
- Snow-related budget: Salt budget is $821,674; overtime budget, $108,000
- Equipment: Seven plow trucks, two end loaders
- Crew: Seven employees
- Salt/sand on hand: 600 tons of straight salt; 200 tons of salt/sand mix
- Miles of streets: 75 straight miles, 150 lane miles*
- Timing/strategy: Drivers leave work at 3:30 p.m. as normal if the storm hasn’t started yet, and get called back in when needed; police notify of deteriorating conditions overnight.
- Snow-related budget: Annual budget is $150,000, which covers overtime costs, equipment and supplies. Of that figure, $80,000 is for salt and sand.

- Sand/salt on hand: Under contract for 800 tons of salt this year
- Miles of roads: 1,150 miles of gravel and paved roads
- Timing/strategy: No plan applies to all storms; will pull plows if there are white-out conditions that make it unable to see and unsafe for employees; with 3 to 4 inches of snow and ideal operations, all roads can be covered once in 10 hours.
- Snow-related budget: $440,000
- Equipment: 12 snow plows (one for each snow route); end loaders and graders used as back up units.
- Crew: 27 employees
