Denver staff outline plow priorities, materials and cost of winter operations
Summary
City street‑maintenance staff told the mayor and Denver City Council the snow program can mobilize nearly 300 people on the largest storms, uses pre‑treating liquid brine and a mostly salt dry material, and estimates seasonal costs between $12 million and $25 million.
Denver street‑maintenance staff briefed the mayor and City Council on the city’s snow‑fighting plans, explaining how routes, staffing and materials are deployed during storms and how residents can report problems.
City presenters said the program scales up substantially for major storms. “At our highest tier storm, almost 300 people that could be deploying to fight snow,” a presenter said, describing staff drawn from street maintenance, wastewater and Parks and Recreation when required. Staff said main routes are handled by a 24‑hour rotation of CDL operators and that residential routes (RSP) deploy only in tier 3 and tier 4 storms.
On materials, staff described a two‑step approach: a liquid pre‑treatment applied ahead of storms to critical locations and a dry material used during storms. “We put [liquid] on ahead of the storm,” a presenter said. “Then when the main storm starts … we switch to our dry deicer, which is essentially salt.” Presenters emphasized that plowing does the heavy lifting: materials assist in melting residual accumulations after plows clear the bulk of snow.
Staff said the city uses multiple forecast sources (National Weather Service, AccuWeather and local forecasts) and maintains a public snow webpage and a plow‑tracker tool. They encouraged residents to call 311 during storms to report unserved areas so supervisors can redeploy crews.
Council members pressed for details about schools, bike lanes, steep hills and bus stops. A council member said parents in east Denver report that side streets near schools often remain unplowed, preventing students from getting to class; staff replied that most school routes are attached to A or B routes but invited follow‑up for specific schools that may have been missed. On protected bike lanes and pedestrian bridges, staff said specialized, smaller equipment is required—big plows cannot access many protected infrastructure locations—and that the city currently borrows additional small sweepers from Parks and Recreation to cover demand.
Staff gave an estimate for the seasonal cost of snow operations between $12 million and $25 million, noting the range varies with storm frequency and severity and includes equipment, materials, overtime and fleet maintenance. They described some heavy‑equipment hauling and curb‑to‑curb snow removal in constrained downtown areas during very large storms as possible but resource‑intensive and infrequent.
On sidewalks, presenters said city rules require property owners and businesses to clear sidewalks and ADA ramps after snow stops (businesses must clear immediately; residences have around 24 hours) and noted an enforcement fine cited in the briefing. The presenters urged residents to report unaddressed sidewalks and high‑impact ice conditions via 311 so cases can be tracked and addressed.
The briefing closed with staff thanking council members for their questions and reiterating that the city can adjust routes or add notes to plow runs when constituents report recurring problem spots.
