Paper yard bags and bundled brush/tree limbs

Paper yard bags may be used for yard waste 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 no more 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. ​​

Preparing compost and cart

Make sure to prepare ​your co​mpost and compo​st cart​ properly for timely service and to avoid odors.​​
