Summer Road Maintenance Projects

Bridge Maintenance

Our 186 bridges are inspected every 2 years and through those inspections we sometimes find repair and maintenance work that needs to be done to preserve the bridge structure and keep it safe for travelers. That work often includes bridge scour projects, either removing excess soil from stream channels or replacing soil around foundations that has been washed away during high water events.

No further work necessary at this time.

  • What: Reset retaining wall blocks on the SE corner of the bridge along Firwood Creek.

32806

No further work necessary at this time.

  • What: Remove remnants of an abandoned beaver dam on the upstream side of the bridge. 
  • Why: To assist with drainage and to keep the stream channel centered under the bridge.
  • When: This project is expected to take one day to complete; work to be scheduled between July 15 and September 30, 2019.

32806

No further work necessary at this time.

  • What:  Extend and repair a retaining wall on a concrete culvert which carries an unnamed tributary of the Clackamas River under Clackamas River Drive.
  • Why:  During a storm event this past winter, a large tree fell and landed on the retaining wall on the culvert, damaging it significantly.
  • When:  This project is expected to take up to one week to complete; work is scheduled between July 29 and Aug. 8, 2019.
  • Traffic impact:  No road closure is planned, but there will be traffic delays of up to 20 minutes at a time.
32806

No further work necessary at this time.

  • What:  Excavate accumulated sediment and invasive species from the stream channel.

Project requires additional work to be done likely during the fall of 2019, pending design and permit approvals.

  • What: Remove excess concrete from bridge footings. 
  • Why: Excess concrete is preventing proper inspection of both bridge footings.  
  • When: This project is expected to take up to two weeks to complete; work is scheduled between Aug. 14-22, 2019. 
  • Traffic impact: No road closure is planned, but there may be traffic delays of up to 20 minutes at a time.
  • Additional work potential: After the excess concrete is removed, the bridge footings will be inspected for damage and/or erosion. It is possible that additional work will be needed in the future

A chip seal is a coating of liquid asphalt and rock chips applied to the existing roadway to extend the life of the pavement. There are four steps in the chip sealing process – applying an oil patch to the most degraded areas, putting down the chip seal, sweeping up excess rock chips and fog sealing (applying a thin coat of asphalt on top of the chip seal).

30991

Though your street is in basically sound condition, it needs routine maintenance to protect it. Chip sealing, which is effective for 7-10 years, stops water from seeping through the surface and damaging the pavement and road base. It costs less to apply chip seal to the street surface than to fix the street base if it is damaged.

30991

Once oil patches are applied, they are allowed to cure for one-two weeks before the chip seal is added. The sweeping and fog sealing are done as soon as possible after the chip seal, usually within 1-2 days based upon weather and the availability of work crews. While the surface can be driven or walked on at any stage, after the process is complete it takes about two weeks before the chip seal is firmly set.

30991

If it is raining or if rain is in the forecast, we will assign our crews to other work for the day. Chip seal must go on a dry surface. That is also why we ask that you make sure any sprinklers are turned off beginning at midnight the night before the chip seal work is scheduled.

30991

You will receive a notice at your door a few days ahead of time. If it does rain, work may be delayed.

30991

Please move your car off the street from the time the chip sealing begins to the completion of the fog sealing process – a period of approximately 2-3 days. You will always be able to drive through the area, but the entire street surface must be available for the work crews. Please also let family, friends and delivery people know not to park their vehicle on the street during that time period. If a vehicle is left on the street, we try to find the owner, but delays cost tax money. Therefore, cars not moved by the time the work begins will be towed at the owner's expense. If your car is towed, contact the Sheriff's Office, 503-655-8441.

Pavement Rehabilitation

Pavement rehabilitation includes treatments that extend the life of an existing road surface such as surface sealants, patching short spans of roadway and asphalt paving. These proactive measures add structure to the road, remedy pavement distresses, and maintain a road's condition to defer full reconstruction further in the future.

See the Transportation Projects Map for road maintenance and improvement project locations. This year's scheduled pavement preservation projects includes over 15 miles of roads in unincorporated Clackamas County, including the following large projects.

Pavement Preservation

To extend the life of a road, surface treatments are applied the existing roadways throughout the county including slurry seal and chip seal.

A slurry seal is a coating of liquid asphalt; a chip seal is a coating of liquid asphalt and rock chips.
