Setting the Standard

In 2018, Arapahoe County Public Works became the 137th agency in North America and the first County in Colorado to earn accreditation through the American Public Works Association. Less than one percent of the nation’s public works agencies have earned this distinction. Accreditation symbolizes the department’s commitment to continual improvement to the quality of life for Arapahoe County citizens.
