Tree Branch/Organics Drop-off

The Tree Branch/Organics Drop-off event allows Thornton residents to recycle tree branches, limbs, and organic materials at the Infrastructure Maintenance Center (IMC) located at 12450 Washington Street. Residents must enter through the north entrance at 126th Avenue & Ogden Street and are required to provide proof of residency and unload their materials themselves. Only car, pickup, or single axle trailers are permitted, and any organic material must be opened on site, with the exception of fully compostable kitchen bags up to 3 gallons. Please note that no commercial or landscaping companies are allowed, and restrictions prevent the dropping off of dirt, sod, or rocks. For more information, visit the Thornton website.
