Coconino Estates Improvements Continue This Summer, Upgrades to Roadway and Utility Infrastructure,

As the Coconino Estates Improvement Phase I Project continues along Navajo Road, Navajo Drive and Beal Road, the Coconino Estates Improvement Phase II Project is scheduled to begin this summer on Crescent Drive, Navajo Drive, Talkington Drive, and several side streets off Talkington Drive. Pending Council contract approval, Phase II work will take place over two seasons, beginning in Summer 2021 on Crescent and Navajo and ending in Fall 2022 on Talkington and side streets. 

Major Infrastructure ImprovementsPreparation for asphalt paving continues along Navajo Drive

In general, improvements consist of replacing all roadway infrastructure and existing water and sewer mains, water and sewer services, fire hydrants, and manholes with a few exceptions. When both phases are completed, the Project will install 6,500 feet of waterline and 6,400 feet of sewer line, replacing infrastructure between 56 and 94 years old. This is part of Flagastaff’s Aging Water and Sewer Infrastructure Replacement Programs. 

Coordination Saves Time and Money

This Project combines Road Repair and Street Safety Sales Tax Funds with Water Services Funds to take advantage of costs savings achieved by delivering both roadway and utilities projects at the same time.
