​Trash & Recycling

​The Environmental Services Team provides curbside trash and recycling collection services to over 29,000 homes in the City, as well as a number of other collection services for our citizens. The collection service program is operated as an enterprise fund, meaning that all costs associated with providing the various services are covered by user fees.
