Curbside Yard Waste

October 7, 2021
Due to ongoing labor shortages, you may be experiencing delays in the collection of yard waste. As a temporary measure to address this issue, residents who have small amounts of yard waste should place it in the container with their trash as space allows. Yard waste that does not fit in with trash should be set out separately. Yard waste may not be collected on regular collection days, so residents are asked to leave their bagged yard waste at the curb until it is collected.
