Street Priorities

How we decide where to start
Town streets are classified based on the street function, traffic volume and importance to the welfare of the community. Two categories and four priority rankings have been established.

Primary streets
  • Priority 1: Streets classified as arterials, major collectors and industrial and commercial business areas. These are typically high-volume streets that connect major sections of the Town and provide access for emergency fire, police and medical services. (It's worth noting that CDOT is responsible for plowing its roads in Castle Rock, such as Founders/Meadows Parkway, Interstate 25 and U.S. Highway 85.)
  • Priority 2: Streets that are classified as minor collectors and school bus routes or roads providing access to schools.
Residential streets
  • Priority 3: Low-volume and residential streets
  • Priority 4: Cul-de-sacs and alleyways
Snowplowing Information
Snowplowing and / or ice control will be completed for each storm event on primary streets (Priorities 1 and 2) when the accumulation of snow or ice is predicted to be more than 4 inches on the roadway

Snowplowing will be completed for each storm event on secondary streets (Priorities 3 and 4) routes when the accumulation of snow or ice is predicted to be more than 4 inches between Nov. 15 and March 15. Snowplowing also will be completed when the accumulation of snow or ice is predicted to be more than 8 inches prior to Nov. 15 or after March 15.

When the Town clears snow from neighborhood streets, residents can expect one lane to be cleared for emergency access.
