Sammamish, WA Parking Rules: Curb Color Rules (2026)

Sammamish's code does not establish a painted-curb color system (red/yellow/white/green) like many California cities. Instead, curbside parking restrictions are conveyed through traffic-control signs and the state stopping, standing and parking prohibitions adopted by reference in SMC 46.30.070, namely RCW 46.61.570 and 46.61.575. Those statutes prohibit standing or parking within 15 feet of a fire hydrant, within 20 feet of a crosswalk at an intersection, within 30 feet of a flashing signal, stop sign or yield sign, within 20 feet of a fire-station driveway entrance, and on sidewalks or planting strips - the functional equivalents of painted no-park curbs. Sammamish's signature local curb-clearance provision is SMC 46.30.080, which restricts parking near residential mailboxes so postal carriers can reach them: city ordinance prohibits parking within five feet of an individual mailbox between 10 a.m. and 5 p.m., and imposes a 24-hour, seven-day-a-week parking ban within five feet of collective (cluster) mailbox units. SMC 46.30.085 provides enhanced penalties for repeat civil parking infractions, which can apply to repeat curb/mailbox-clearance violations.
