The City of Centennial is Colorado's newest city, located in the southern Denver metropolitan area, entirely within Arapahoe County.
Centennial is adjacent to the cities and towns of Aurora, Englewood, Foxfield, Greenwood Village, Highlands Ranch (unincorporated Douglas County), Littleton, Lone Tree, and Parker.
Total Area
Centennial encompasses 28.24 square miles, or 18,071.24 acres.
Residents voted to incorporate the City of Centennial on September 12, 2000 and elected its first officials on February 6, 2001. Centennial officially became a city on February 7, 2001.
The quest for a new city took almost two and half years. The campaign included victories in the State Legislature and State Supreme Court. Formation of the new city was approved by a 77 percent margin in the incorporation election. It was the largest city incorporation in U.S. history.
Centennial is a vibrant community that offers the benefits of city living and the pleasure of suburban and semi-rural life in beautiful and well-kept neighborhoods. A flourishing economy, diverse and friendly business climate and an array of amenties offers visitors, residents and businesses a high quality of life experience.
While we are still a young city, we are excited about the opportunities that lie ahead as we shape our future and make Centennial the place to visit, work, and play.
