Kennewick, WA Trash & Recycling: Yard Waste Collection (2026)

Kennewick's residential yard-waste program is narrower than the year-round green-cart programs found in western Washington cities. Per WM Northwest's published Kennewick service information, bagged leaves are collected on the regular weekly garbage day during the first full week of November, December, and January only - three weeks total per winter season. Leaves must be tied in standard-size lawn-and-leaf bags and placed alongside the garbage cart (not in it). Branches, grass clippings, and other yard waste outside the three-week leaf window go in the regular garbage cart (subject to the 65-pound weight limit per 32-gallon cart) or to self-haul at the WM Kennewick Transfer Station, or can be composted on-site. Outdoor burning of yard waste is heavily restricted. RCW 70A.200.040 and WAC Chapter 173-425 prohibit residential yard-waste burning inside urban growth areas where the Department of Ecology has determined reasonable alternatives are available - Kennewick lies inside the Tri-Cities Urban Growth Area, so residential yard-debris burning is generally prohibited. The Benton Clean Air Agency administers local burn-permit and burn-ban authority. Outside urban growth area boundaries, burn permits may be required from the Washington Department of Natural Resources under RCW 76.04.660 (forest-protection authority over fire hazards on land within DNR jurisdiction). Even where burning is allowed, the burn cannot include rubber, plastic, asphalt, garbage, dead animals, petroleum products, or paint, and is suspended during burn bans called by the Benton Clean Air Agency or the Tri-Counties Fire Marshal.
