Snow Information

How the Town manages snow

Before a storm, the Town’s Public Works Department obtains meteorological data from a number of weather services and local media. After data collection, a team of plow and truck operators are put into action to manage over 740 lane miles of roadway throughout Town. In order to keep Castle Rock residents on the move, the department has established methods of snow management.

How the Town prioritizes plowing

Streets are classified as either primary or residential streets, based on function, traffic volume and importance to the community. Primary streets are then split into first and second priority, and residential streets are split into third and fourth priorities.

  • Priority No. 1: High-volume, primary streets that connect major sections of Town. Think Plum Creek Parkway, Wolfensberger Road or Mikelson Boulevard, for example. 
  • Priority No. 2: Smaller, primary streets and roads that provide access to schools.
  • Priority No. 3: Residential streets.
  • Priority No. 4: Cul-de-sacs and alleyways.

Please reference the interactive snow plow route map to view all primary and residential roads, color-coded by priority.

Residential streets 

Residential streets are plowed after primary roadways, and when roadway snow accumulation is expected to exceed a specified amount. 

  • From March 15 to Nov. 15, snow accumulation on residential streets is expected to exceed 8 inches during a snow storm before being cleared by plows, due to warmer temperatures. 
  • From Nov. 15 to March 15, snow accumulation is expected to exceed 4 inches on the roadway before being cleared by plows.

When plowing residential streets, plow drivers will make every effort to facilitate two way traffic as best as possible. Vehicles parked on the side of the roadway can affect snow plowing operations.
