How Does the City Decide When a Street Needs to Be Repaired? 

The city owns and maintains more than 225 miles of roadway. Consistent pavement analysis, maintenance and repair helps keep these roadways in good condition. The city streets are analyzed on a routine basis and given a Pavement Condition Index (PCI) score. Streets are scored on a scale from 0 to 100. A score of 0 means that the pavement on a given roadway is in a completely failed state, while a score of 100 is assigned to roads with brand new pavement. The current average PCI score for city-owned and maintained roadways is 74.  

Many factors are considered when planning pavement maintenance projects (existing roadway conditions on existing roadway conditions known through PCI scores, current and projected budget, coordination with other Capital Improvement Projects, etc.). While preventative maintenance strategies such as crack sealing and slurry sealing are utilized when possible, roadway conditions eventually get to a point where more intensive repairs are necessary. 

Street overlays are one of the main repair strategies the city utilizes to bring damaged roadways back to life. During this process, the city typically has the existing layer of asphalt removed by grinding or milling the surface before applying a new layer of asphalt. This new asphalt application should last anywhere from 10 to 25 years depending on numerous site-specific factors. 

The city performed street overlays in the Vose neighborhood in June and plans to overlay multiple locations in the Sexton Mountain and Southwest Beaverton areas between July and September.
