Paper yard bags and bundled brush/tree limbs

Branches, tree limbs and brush are collected at the curb but must be under 4' in length. Brush and branches can be tied together in a bundle with natural twine not exceeding 18" in​ diameter. Individual tree limbs must not exceed 6" in diameter.

Participating residents must place their compostable material 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 not be placed in lanes of travel, either roads or bike lanes, instead using yard extensions or buffer zones as directed.  

Dumping yard trimmings/waste in parks or other public places is not allowed. Please make use of the drop-off facility mentioned below. 

Preparing compost and cart

Make sure to prepare ​your compost and compost cart properly for timely service and to avoid odors.​​

For winter composting, the colder temperatures mean changing up how to put material in carts. Our winter composting page ​has all the tips and tricks that may help.
