Mill and Overlay

Streets receiving a mill and overlay treatment will have the surface of the road milled for the entire width of the street. A new asphalt surface will be placed on the roadway approximately 10 days after the milling is complete. Access will be provided by flaggers working in the construction zone.

Concrete Replacement

Streets receiving a mill and overlay will also receive concrete rehabilitation the year prior to the pavement treatment. This effort repairs broken curbs, gutters, sidewalks and other concrete structures that if left unrepaired will shorten life of the major rehabilitation investment. As part of this work, curb ramps will be repaired and brought to current Americans with Disabilities Act (ADA) standards.

Slurry Seal

Street segments receiving this treatment will receive a new wearing surface on top of the existing asphalt. The street is closed for approximately 4 hours for the application of the slurry seal as well time for the new surface to dry. This process seals the cracks in the road as well as protects the existing asphalt surface.

Crack Seal

Crack seal is the process of cleaning out existing cracks in the road and placing a hot asphalt rubber to protect moisture from entering the crack. This process is performed with a mobile operation in which a flagger will help assist providing access through the construction zone. Streets receiving a slurry seal will also receive a crack seal treatment.

Everyone should feel safe on our streets, regardless of age or ability or how they get around. With this goal in mind, the City has developed and adopted a Safety Action Plan (SAP) to improve transportation safety for all users whether walking, biking, using a mobility device, taking transit or driving. The SAP was approved by Centennial City Council on April 15, 2025.

Benefits of City Ownership

Owning and maintaining streetlights provides numerous advantages for the community:

• Lower Utility Costs: City ownership results in a reduced utility rate, saving taxpayer dollars.
• Energy Efficiency: Transitioning to LED lighting will provide significant utility and energy savings.
• Cost-Effectiveness: The estimated payback period for this investment is 17 years.
• Proactive Maintenance: The City can now repair and maintain streetlights promptly, enhancing reliability and safety.
• Improved Community Aesthetics: Ownership allows for better integration of streetlights with the City's design and beautification efforts.
• New Revenue Opportunities: The City can generate additional revenue through small cell attachments, electrical vehicle station mounts and other technologies.

The City's street network consists of approximately 425 miles of paved public streets. A computerized work management system logs service requests, creates work orders, schedules maintenance work and documents work completion. The department utilizes a pavement management system to evaluate the condition of the street network and prioritize maintenance and rehabilitation work.
