Street Preservation Program

Street Preservation Projects

In 2022 approximately $1.1 million is being invested to improve pavement conditions in neighborhoods throughout the city.  This year's work includes mill & fill projects with curb ramp upgrades; pothole repair; crack sealing; and lane striping.  Details are listed below.

Mill and Fill Projects

Three locations are scheduled for mill & fill projects where road surfaces will be completely replaced. Crews will come in and remove the existing surface layer, curb to curb, and replace it with a new layer of asphalt.   

Curb ramps at locations within Mill & Fill project areas will be upgraded to current standards under Americans with Disabilities Act (ADA) to improve accessibility and mobility for all per federal requirements, along with additional intersection improvements including pedestrian signage.  

Mill & Fill Project Locations

  1. W Main Street; between NW 10th Avenue and Parkway
  2. E Main Street; between NE 16th Ave and just east of SE 20th Avenue
  3. NW 13th Avenue

Pothole Repair

Potholes are repaired using hot asphalt where sections of roadway have developed deep potholes and crumbling asphalt. Crews dig out damaged areas to a depth of about one foot before filling and sealing the areas with hot asphalt. This process helps preserve the road until funding is available for a more permanent fix on the entire length of the roadway.

Crack Sealing Streets

Crack Sealing Streets

Crack Sealing

The application of asphalt rubber into cracks that occur on the roadway.  Crack sealing prevents damaging water intrusion and prepares the roadways for the more expansive repair including curb to curb slurry seal.    

Slurry Sealing

Slurry seal is cost-effective method of resurfacing smaller neighborhood streets.  This quarter inch layer of water, asphalt emulsion, and coarse sand is applied to streets that are in fair or good condition, as a preventative maintenance measure.  

The longevity of slurry sealcoat is dependent on the traffic load and weather conditions of the affected street.  In general, slurry seal can last anywhere from three to nine years.

Managing Assets & Investment: Pavement Life Cycle

Proactive maintenance and preservation through regularly scheduled crack and slurry sealing, every 10 - 15 years after a street’s construction is the most effective method for extending the life of pavement. Established engineering studies show that a street left unmaintained after that timeline will deteriorate rapidly and necessitate a more detailed and expensive method of repair.
