Street Operations

It is important to the City to have clear, well-maintained and well-lit roads to ensure that traffic flows as smoothly and safely as possible. In order to accomplish that, the City must manage and monitor several factors.

The City manages these street operations:

  • Pothole & pavement repair
  • Signs and markings
  • Street lighting
  • Street sweeping
  • Snow & ice response

The City monitors:

  • Sight Distance Triangles - Public and Residential areas

City Street Operations:

  1. Potholes
  2. Signs & Markings
  3. Streetlights
  4. Street Sweeping
  5. Snow & Ice Response


Potholes start in cold temperatures when groundwater freezes and expands. Once the ground thaws out, it returns to a normal level, but the pavement pushed up during the ground freeze remains raised. This causes a gap between the pavement and the ground. Vehicles riding over these gaps cause the road surface to crack and fall into that hollow space. To report a pothole, please use the Report an Issue link and include the exact location.

  • Maintaining Redmond’s streets helps ensure that the investments made into our roadway infrastructure are preserved. A Pavement Condition Index (PCI) rating of at least 70 or better for all streets combined is an indicator of good roadway maintenance. Redmond is currently at a 71 PCI (a preferred level of service), the rating has been declining steadily since about 2003 as infrastructure built in past decades ages. 

The primary reason for the decline is the high cost and frequent maintenance needed for Redmond’s arterial streets. There are 219 lanes miles of arterial streets and 128 lane miles of local streets (each local street has two lanes and arterial streets have multiple lanes.) Compared to either Bellevue or Kirkland, Redmond spends considerably less per lane mile of arterial than either of those jurisdictions, despite having a disproportionately higher number of arterial streets. This is an important distinction for Redmond since the cost to fully maintain an arterial lane mile is about four times as expensive as a local street lane mile.

What is Crack Sealing?Image of unfilled pavement cracks and filled pavement cracks

Crack sealing is a proven pavement preservation technique that can extend the expected life of a roadway by up to 8 years. Crack sealing prevents water from seeping into cracks in the pavement where it can freeze, expand, and damage the pavement. Crack sealing helps reduce structural deterioration, minimize pothole formation, and can prevent pavement distresses. It helps maintain streets in good condition, postponing the day we need to repave or rebuild them.

Why Crack Seal?

 Asphalt crack sealing is a cost-effective way to maintain the roadway surface because it helps to prevent larger maintenance projects down the road. Pavement that continues to deteriorate requires repair and replacement methods that can cost 3-4 times more than crack sealing. Approximately 70% of Redmond’s roadways currently fall within the Pavement Condition Index (PCI) range for crack sealing (70-85).

When Do We Crack Seal?

Crack sealing is recommended during dry conditions when pavement temperatures are neither too hot nor too cool – generally fall and spring.
