Snow and Ice Removal Policies
This page provides a brief overview of snow and ice removal policies and procedures for cities, towns, and counties in Washington State, including examples of emergency parking restrictions and sidewalk clearance requirements.
Cities and counties often prioritize their road networks for snow and ice removal, focusing first on high-volume arterials. Less-traveled roads receive a lower priority and, especially in low-density residential areas, some roads may not be plowed at all.
RCW 47.24.020(6) requires cities and towns to clear snow from state highways within city limits, except that the state shall plow those roads “when necessary.” The 2013 City Streets as Part of State Highways Conformed Agreement clarifies the meaning of “when necessary,” establishing that the state will plow snow, with city concurrence, on the traveled lane of a state highway on the way through cities without adequate snowplowing equipment. (See Section D - Snow and Ice Removal.)
Several Washington-based court decisions have established that a public agency cannot be held liable for damage or injuries caused by snow and ice if it has not had a reasonable opportunity to clear the streets. See Leroy v. State (2004), Wright v. Kennewick (1962), and Bird v. Walton (1993).

Municipalities in Washington have adopted a variety of parking restrictions to help facilitate the snow and ice removal process, including temporary parking prohibitions. Some of these laws take effect upon a certain level of snow accumulation, while others only take effect if the jurisdiction has declared a snow emergency.
These provisions typically allow local law enforcement to tow noncompliant vehicles and issue citations.
- Cheney Municipal Code Sec. 11.48.070 and Sec. 11.48.080 — Prohibits vehicles from parking or standing on any street or city right-of-way between midnight and 6 AM (3—6 AM in central business district) if two or more inches of snow have accumulated. Vehicles may be impounded.
- East Wenatchee Municipal Code Sec. 10.08.030 — Requires vehicles be parked on the even-numbered side of the street on even-numbered days and the odd-numbered side on odd-numbered days, to facilitate snow removal during the months of December, January, and February.
- Moses Lake Municipal Code Ch. 10.14 — Allows municipal services director to prohibit parking on parts of or all streets as necessary whenever snowplowing is necessary or anticipated based on weather forecasts. City may remove and/or ticket vehicles.
- Puyallup Municipal Code Sec. 11.08.100 — Provides authority to remove vehicles for emergency snow removal, without prior notice to owner.

- Yakima Municipal Code Sec. 8.88.060 — Prohibits parking on designated snow routes during snow alerts.
Many jurisdictions assign responsibility for sidewalk maintenance — including snow and ice removal — to the owner or occupant of the abutting property. However, the specifics can vary significantly.
Some jurisdictions require snow and ice to be removed by a certain time - either a set time of day (typically no later than noon), a certain number of hours after the snow has stopped falling, or a combination of the two. Others use more vague language, requiring removal as soon as practical.
Some ordinances clearly prohibit property owners/occupants from dumping snow and ice onto public rights-of-way or anywhere that would obstruct fire hydrants or traffic signs. One of the examples below (Wilbur) declares snow, slush, or ice on sidewalks to be a nuisance, while another (Cheney) exempts snow blowers from the city’s normal noise nuisance ordinances.
Practice Tip: Shoveling snow is a physically strenuous task. The combination of the physical strain and cold temperatures can increase the risk of heart attacks, particularly in older individuals, not to mention the risk of injury from slips and falls. Elderly residents or people with disabilities may be physically unable to shovel snow, in which case some jurisdictions maintain lists of volunteers who can assist them.
For example, see Walla Walla’s snow removal assistance information on its Snow and Ice Control webpage.
- Cheney Municipal Code Ch. 12.32 — Prohibits dumping of snow from private property onto public rights-of-way. Sec. 9A.10.020(C) exempts snow blowers and snow removal equipment from noise nuisance laws if two or more inches of snow have fallen.
