Red crane bids farewell; Mapleton truck traffic reduced
In early December, the red tower crane was dismantled and removed from the plant site. Since spring 2014, the red tower crane has serviced the bulk of major construction for all new structures across the site.
Now that the tower crane has departed and the bulk of major structural pours are complete, Mapleton Drive neighbors will see a substantial reduction in truck traffic. Over the next few weeks, crews will be working on the remainder of the Mapleton sidewalk and bio swales. This work will remove the western construction entrance on Mapleton Drive. Moving forward, the main access to the site will be in and out of Kenthorpe Way.
Ozone system – northeast of site
Crews are busy installing equipment for the new ozone system, inside the ozone generation building. They are also working on the roofing and skylights. The building has been tented, which allows crews to apply the brick veneer and architectural finishes in dry conditions.
The final concrete decking was poured for the ozone contactor basin in late November. The basin is now undergoing a water test.
Miscellaneous duct bank and piping work continues around the new ozone structures. During these activities, neighbors close to the site should expect some noise and vibration during work hours.
Site improvements and hardscaping
Hardscaping and site improvements are ongoing across the site. This week, the Mapleton site fence was shifted to the edge of the curb, to enable crews to continue working on the bio swales and sidewalk. Weather permitting, crews will soon begin working on the rooftop gardens on the electrical, admin and finished water pump station buildings.
Site improvements, stone walls, sidewalks and hardscaping work includes digging and preparing the site, placement of materials, forming, compacting, pouring concrete and saw-cutting stone. During this work, neighbors close to the site should expect an increase in intermittent noise and vibration from equipment.
Neighborhood construction meetings – next meeting December 20
Meetings are held once a month at the Robinwood Station, 3706 Cedaroak Drive, West Linn, on the third Tuesday of the month at 6 p.m. The next neighborhood construction meeting will be held on Tuesday, December 20 at 6 p.m. Please attend to stay up-to-date on construction progress in West Linn and ask the project team questions.
