Snow & Ice Control FAQs

Public Works sets a time-based goal depending on the severity of the winter weather. Primary and secondary roads are the main priority. The goal is to get every house within a quarter mile of a plowed and treated street after the primary and secondary roads are complete. Residential streets are plowed last. 

Level 1: Pre-treatment
Level 2: One inch or less; 24 hours
Level 3: One to six inches; 32.5 hours
Level 3: Six to ten inches; 40 hours
Level 4: More than ten inches; 48 hours
Level 5: Sustained winds of 30 mph; 48 hours

The goal is to have all streets plowed and treated within the stated time frame (see above FAQ) once precipitation and/or sustained winds end. For example, if more than 10 inches of snow falls and the precipitation ends at 2 a.m. on Sunday, Public Works will have all roads treated and plowed by 2 a.m. Tuesday.

Primary Roads: Major four-lane roads or two-lane roads with high volume
Secondary Roads: Minor thoroughfares
Residential Streets: Local streets, including dead-end streets and cul-de-sacs

MoDOT is responsible for all of MO-291, MO-150, U.S. Highway 50, most outer roads, and the interstates.

Rock salt: Anti-icing material and also a de-icing material
Salt brine: Anti-icing, saltwater solution used to prevent winter precipitation from bonding to the pavement
Calcium chloride mixed with rock salt: Used when temperatures drop into the teens
Beet juice mixed with brine and rock salt: Accelerates melting and helps materials adhere to the roadway

If you believe your street was missed, contact Public Works at 969-1870. It is important to note the City does not have a bare pavement policy, so some streets may still have snow even after a plow has treated the area. 

While residents are not legally required to move vehicles off the street, it does help plow drivers if there are fewer obstacles, such as basketball hoops and trash cans on the street. We also ask residents to remain patient. Crews have more 1,000 lane miles of streets and cul-de-sacs to plow and treat.

Report damage to Public Works at 969.1870. During heavy snowfall it is difficult for crews to distinguish between the curb and road and some yard damage may occur.

There is not an ordinance requiring property owners to clear sidewalks. However, property owners are encouraged to clear snow for safety reasons.
