Mono County, CA Parking Rules: Snow Removal Parking Rules (2026)

The Mono County Department of Public Works Road Operations is responsible for 679.26 miles of county roadway. Each maintained road is assigned a snow-removal priority from Class 1 to Class 5, a classification system established in 2004 by Resolution R04-069. Class 1 roads are paved school-bus routes and major collector roads that provide the main access for communities to the State Highway System and that reach fire, paramedic, and Sheriff facilities — these are plowed first and kept open continuously when possible. Class 4 roads (other Forest roads, remote single-residence roads, or high mountain roads with avalanche potential) are plowed only after higher classes and only after the storm passes, during daylight only. Class 5 roads are primarily Forest roads closed for the winter. Plowing generally begins at three inches or more of accumulation. Importantly, "Mono County does NOT clear snow off of dirt roads." The County can restrict parking to keep plow routes clear under CVC §22507, and a vehicle obstructing a plow or traffic can be removed under CVC §22651(b). For new development, General Plan Section 04.300 requires on-site snow-storage areas for commercial, industrial, and multifamily projects, sized as a percentage of the parking/access area (ranging from 25% to 65% depending on roof snow load) and kept clear and accessible to snow-removal equipment. (The Town of Mammoth Lakes runs its own separate snow program within town limits.)
