Paper yard bags and bundled brush/tree limbs

Paper yard bags may be used for yard trimmings such as leaves, weeds and other vegetation. Bundled brush or tree limbs, four feet or less, can be tied with natural twine in bundles up to 18 inches in diameter, can be left at the curb for pickup. Individual tree limbs must be less than 6 inches in diameter.

As bags can be difficult to service at times while also posing a greater injury and health risk to staff, we are encouraging all composters, who can, to take advantage of carts. If you must use paper yard bags, please don’t overload them. If you can’t lift it comfortably, neither can city staff.

Participating residents must place their compostables at the curb before 7 a.m. on their weekly waste collection day — allowing at least 3 feet between each cart with clearance from any obstacles overhead. Carts should be placed on lawn extensions, whenever possible, and never left in bike lanes.

These items are prohibited from compost carts and yard waste bags:

  • Plastic bags or containers.
  • Trash and recyclables.
  • Dirt, rocks, stones or gravel.
  • Sawdust.
  • Branches 6 inches in diameter or over 4 feet in length.
  • Painted or treated wood.
  • Animal waste or cat litter.
  • Tree stumps.
  • Diapers.
