12th Ave NW Basin Drainage Improvement Project July 2023
12th Ave NW Basin Drainage Improvement Project
Construction workers installing a section of the new drainage system on 11th Ave NW
Hello Broadview community! Construction for the 12th Ave NW Basin Drainage Improvement project has continued steadily through the summer months on the underground pipe and conveyance work. Crews have completed the following tasks since our last update:
Completed installation of the new drainage system along 10th Ave NW
Began installation of the new drainage system along 11th Ave NW, beginning at the south end of the project west of the pump station and working their way north
Looking ahead, the contractor expects to:
Continue installation of the new drainage system along 11th Ave NW until reaching the NW 122nd St intersection. This is the last segment of underground pipe to be installed.
Begin roadway restoration work on NW 125th St as soon as late July or early August. This work will begin at the 10th Ave NW intersection and continue eastward until reaching the 6th Ave NW intersection. Paving is planned for a couple dates during mid to late August. Any residences with driveway access impacts will be notified.
Continue miscellaneous construction activities throughout the project area
Upon completing the underground pipe installation work on 11th Ave NW and the roadway restoration work along NW 125th St, the contractor expects to continue roadway restoration at the southern end of the project on 11th Ave NW. They plan to work their way north along the project area doing roadway restoration until reaching the 10th Ave NW and NW 125th St intersection. The contractor will restore sections of the roadway as required by regulations, as well as any additional roadway areas that were disturbed by this project’s construction activities. Construction for the whole project is expected to be completed in fall 2023.
To protect trees near the work area, the project is following the tree protection plan and direction from City arborists who have visited the site.
See the yellow areas on the map for approximate work areas. All work will take place in the right-of-way.
We want to thank the community for keeping everyone safe by staying away from the construction work areas as much as possible. Great job, keep it up everybody!
