Centennial

Centennial is a municipality in Arapahoe County, Colorado, United States, spreading across residential neighborhoods interspersed with shopping centers, office buildings, and parks. A network of walking trails connects these different sections of the community, situated at approximately 1,777 meters elevation.

The incorporation occurred in 2001 and marked the largest single municipal incorporation in United States history, beginning with over 100,000 residents. This step arose from residents' desire to gain local control over planning and services.

Youth choirs from different neighborhoods gather at the annual Jingle Jam event, connecting families through shared music during the winter months. This gathering brings together neighbors who might otherwise rarely meet across the sprawling residential areas.

Residents handle city services through an online portal that processes building permits, property searches, and business licensing applications year-round. Most requests can be submitted from home, eliminating the need to visit offices.

The Livable Streets Program transforms residential roads through design changes that slow down cars and create more space for pedestrians. These redesigns often emerge from initiatives by residents themselves, advocating for safer streets in their neighborhoods.
