Mill & Overlay FAQs

Edge mill and overlay projects help prolong the life of a street. The projects are less disruptive to residents and cost significantly less than street reconstruction projects. This page contains answers to residents' frequently asked questions about the process.

What does this project include?
The project includes milling the edges of the pavement and then overlaying the entire surface of the pavement. This is not a complete reconstruction project and the streets will not be perfect when completed.

Why isn’t a reconstruction project planned?
Recent street ratings show the streets in the project area meeting the mill and overlay criteria. Additionally, reconstruction projects are extremely invasive projects that take the entire summer to construct and project costs would be about seven times higher (including assessments).

Will I be charged for any of the costs of the project?
Benefited properties will be assessed 40% of the actual project cost. The minimum assessed amount will be $1,000 for single family properties and $500 for multi-family properties, except that the total assessed amount shall not exceed the actual project cost. 

How can I pay for this assessment?
Exact details of the payment options will be provided prior to the assessment hearing but the property owner has a number of options. Options listed below apply to all projects assessed in 2020.

Note: The standard interest rate for 2020 is 2.67% for assessments of $5,000 or less.

  • Option 1: Full payment without any interest by October 31 the year the assessments are approved.
  • Option 2: Full payment between November 1 the year assessments are approved and November 15 of the following year. Interest on this option will be for the entire year, regardless of when the balance is paid off.
  • Option 3: Payment over the standard assessment term, which is 5 years. Payments would be included in your property taxes.
  • Option 4: Partial prepayment by October 31 the year assessments are approved (minimum amount of $100). The remaining balance would be paid under Option 3.

What does the paint mean?
Most of the paint in the area is used for locating purposes. For example, blue paint in the boulevards indicates the location of water service to a home.

How will the project impact me and will I be able to access my driveway?
Impacts to residents during the project are minor. The contractor will work on one lane at a time while keeping the other open to traffic. The contractor will typically work in front of a resident’s home twice – once to mill the road, which takes roughly 20 minutes, and again at a later date for paving, which may take up to an hour. Residents will be able to get in and out of their driveways during the project but may experience a slight delay if the contractor is working in front of their home. Contractors are typically willing to work with residents to get vehicles in and out with minimal wait.

How long will the project last?
The milling of a roadway and paving can take up to a couple of months to complete. After a roadway is milled, there may be a one- or two-month delay before it is paved.

There is standing water in the street. Will this be corrected?
Standing water in the asphalt will likely be corrected with this project. However water in the curb line may not be corrected, although each case may be reviewed. The mill and overlay project is not intended to correct all drainage and surface deficiencies, but rather to improve the driving surface and extend the life of the roadway.

How long will the new street last?
The new street is expected to last 7-10 years, if not longer. The city’s first edge mill and overlay project was in 2005 on streets that were rated as having a similar condition to the streets in your neighborhood. Those streets are still performing well.

The curb was nicked during the project. Is that normal?
In order to tie the new overlay into the curb, it is necessary to mill the edges of the roadway. Sometimes the machine used to mill the pavement will nick the curb, but these nicks do not affect the integrity of the curb and are aesthetic in nature.

The new overlay cracked after the winter. Is that normal?
After the first winter season following the project, you may notice cracks that appear in the new overlay. These cracks are usually the result of reflective cracking, where the cracks in the old roadway reflect through the new surface, or thermal cracking, which is common in cold weather climates. Both kinds of cracking are typical for a mill and overlay project and do not affect the expected lifespan of the new street.

Who should I contact if I have questions now or during construction?
