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.
