Milton Court pipeline construction continues, exploratory digging begins on Bonita Road
These construction updates will now include all work in Tigard for the project.
See below for specific information on each location:
- Milton Court
- Bonita Pump Station
- Bonita Road Pipeline
Crews continue to install water pipelines on Milton Court, working their way from Bonita Road towards the new Bonita Pump Station. During this time, a single-lane closure is in place and flaggers are directing traffic around the work site. The areas where crews have excavated the street and installed pipe will be left as gravel until the final repaving, which is expected in this summer. In a few weeks, pipeline installation will be complete on Milton Court and crews will begin working on ADA ramps and sidewalks.
Bonita Pump Station
Electrical work is being completed inside the pump station over the next few weeks as well as the installation of the HVAC system. Crews continue to install wall panels (pictured right) on the outside of the building, and roofing will begin in the next few weeks.
Bonita Road Pipeline
Next week, crews will work along the water pipeline route on Bonita Road, beginning at 74th Avenue and moving towards Bangy Road in Lake Oswego. They will dig small holes in the roadway to ensure the pipeline route does not conflict with existing utilities. Workers will use a vacuum truck, small drill rig and small excavator. The holes will be repaired as work progresses. This work will occur between 8 p.m. to 5 a.m., Monday through Friday. During this time, single-lane closures will be in place with flaggers directing traffic. Please expect some temporary delays.
Later this month, a work pit will be excavated in the center lane of Bonita Road near 74th Avenue. This pit will be used by crews to install the pipeline underneath the railroad tracks using an auger bore. More information will be provided soon regarding duration, work hours and traffic control.
About Bonita Pump Station
The Bonita Pump Station will connect with several local water systems including Lake Oswego, Portland and Washington County. This supply collaboration will keep Tigard protected should one water supply become interrupted. Completion is expected in summer, 2015.
Did you know? Tigard's new water system’s storage reservoirs are all covered, meaning fewer opportunities for contaminants to enter the system.
