Sanctioned Maintenance Programs
On-going activities in Transportation Services occur under the "program" umbrella.
Transportation Services programs are sanctioned by the City Council and are established to accomplish significant City objectives. Each program has a systematic focus and a two-year budget dedicated towards program actions taken towards program goals.
Program activities that center around such important elements of the City's transportation system such as:
- Managing the City's infrastructure
The goal of the Bridge Repair Program is to preserve and maintain the City's bridges in good and safe condition while meeting State and Federal requirements.
Total of 38 bridges within the Redmond City limits:
- 19 - owned and maintained by the City
- 19 - owned and/or maintained by other agencies
Maintenance & Inspection
The City's bridges are inspected every two years. Bridges that may be vulnerable to erosion are inspected more frequently.
Bridge maintenance is performed on an as-needed basis. One of the more common bridge maintenance tasks is removing graffiti.
Every two to three years the City conducts a pavement condition rating survey to determine where resurfacing is needed. Segments are grouped together to create a continuous paving area rather than just selecting the worst segments scattered randomly throughout the City.
The Pavement Management Program preserves and maintains Redmond's pavement infrastructure in good condition. Pavement is rated from 0 to 100 (100 is brand new pavement) and are used to quantify a pavement's overall performance and help manage the pavement network. The program strives to sustain an average pavement score above 80.
Resurfacing takes four phases to complete.
- Phase 1: Improve sidewalk ramps, curbs and storm drains.
- Phase 2: Grinding and repairing the existing asphalt surface.
- Phase 3: Hot asphalt overlay with about a two hour waiting period for the asphalt to dry and harden before the street is reopened to traffic.
- Phase 4: The paving machine must run in a continuous, uninterrupted path to provide a smooth surface. Manholes and valves are paved over with the road surface. Afterwards, cuts are made into the new asphalt so manhole castings can be raised level with the surface and the asphalt is patched.
- There are about 219 lane miles of arterial streets and 128 lane miles of local streets (each local street has two lanes and arterial streets have multiple lanes).
- Redmond's average pavement score is 71.
