Each year, the city completes a number of public road construction and public improvement projects to make safer streets with better traffic movement and streamline the maintenance of public property.
Occasionally, projects will cause some traffic delays and temporary disruptions. This page contains details about all street, bridge, stormwater, and other projects currently under construction that may impact traffic in the city.
The annual project map shows some information about all Public Works projects scheduled for the year.

A mill and overlay removes the top two to three inches of the asphalt street. Milling removes the old surface and helps to restore the street to its original shape. Crews then overlay new asphalt. Curb and gutter, sidewalk, storm sewer and commercial driveway repairs are included as part of the project. Thoroughfare roads are treated with this maintenance every 10 to 12 years; and residential streets are treated at least 30 years after they were newly constructed.
This process removes the top 5/8″ of existing pavement from a street. Crews then apply an ultra-thin bonded asphalt, which seals the pavement, and prolongs the life of the street. Curb and gutter, sidewalk, storm sewer and commercial driveway repairs are included as part of the project. Thoroughfare roads are treated approximately every 8-10 years.
Chip seal is used on residential streets to extend the life of aging streets until crews can overlay the pavement.
Chip seal extends the life of your street and is relatively quick to apply, reducing the disruption to the neighborhood. It creates a skid-resistant surface that can be used right away. Chip seal keeps streets in good condition by sealing cracks and preventing water from creating new issues.
Compared to other project types, chip seal provides a better value to taxpayers and residents because it lasts longer and is less expensive.
|Project Type||Cost Per Lane Mile||Expected Longevity|
|Chip seal||$17,600||7 years|
|Total reconstruction||$1.5 million||20-30 years|
Chip seal typically happens during the summer. City staff notify residents with mailed postcards and door hangers before chip sealing begins. These notifications have contact information included so you can call with questions or concerns. Streets remain open and you will have access to your home.
The chip seal process involves spraying a mixture to seal cracks, spreading small chip rocks on the mixture, and rolling the chip rocks to embed them into the street surface.
On the day the work is scheduled, do not park in the street. You can drive slowly on the chip sealed surface during the curing process, but do not brake or turn the wheels of your vehicle sharply within the first few hours of application.
After chip seal is applied, street sweepers will sweep five times to reduce loose rock. Do not park on the street during that week so sweepers can remove the loose rock.
Chip seal application lasts approximately seven years.
The city’s neighborhood street reconstruction program includes pavement replacement, driveway approaches, as well as sidewalks, storm sewers, and street lights. Streets improved with this project type may not need to be rebuilt or repaved for as long as 50 years.
The impact of this project type varies by neighborhood and depends on other needed infrastructure upgrades, but streets often must be closed for weeks or months in order to complete the work. At times, street trees must be removed to accommodate infrastructure, but will be replaced. City staff meet in-person with residents in the area to provide as much notice and information as possible.
Upgrades are funded by the Capital Improvements Program with the 1/8 cent sales tax revenues.
Stormwater projects replace aging and deteriorating corrugated metal pipe with reinforced concrete pipe and new concrete inlet structures in order to safely move stormwater away from property and improve drainage. Some stormwater projects address bank erosion or instability along creeks or rivers. Stormwater projects often involve lane or street closures in residential areas.
