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 700 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, bus routes and roads that provide access to schools.

Priority No. 3: Residential streets.

Priority No. 4: Cul-de-sacs and alleyways of residential streets.

Residential streets 

Residential streets are plowed after primary roadways, and when snow accumulation reaches a specified amount. From March 15 to Nov. 15, snow accumulation on residential streets must total 8 inches before being cleared by plows, due to warmer temperatures. From Nov. 15 to March 15, snow accumulation must total 4 inches before being cleared by plows. 

When clearing residential streets, plow drivers will make a single pass to ensure one lane for emergency access. After one lane is cleared, residents should make an effort to get to and drive on that path.
