12th Ave NW Basin Drainage Improvement Project Project Update, April 2023
|
From Seattle Public Utitilies Hello Broadview community! Since last December, construction for the 12th Ave NW Basin Drainage Improvement project has been paused on the underground pipe and conveyance side of the project. Work is now set to resume, and construction crews will soon be returning to the work site. Preparation work for resuming construction is expected to begin as soon as May 1, 2023, with work taking place Monday through Friday, from 7 am to 5 pm. During the first two weeks, crews will be getting the work site ready, moving in materials and equipment, and conducting potholing work along parts of 10th & 11th Ave NW. This potholing work is for investigating underground conditions and will involve digging and construction related noise. Full construction, involving trenching and underground work, is expected to resume as soon as May 15, 2023. The contractor expects to begin work along NW 122nd St between 10th & 11th Ave NW, where we are anticipating a full street closure for around 2 weeks once full construction resumes. Traffic will be redirected, and access to driveways near the closure will be maintained via a detour. We will be reaching out to residents directly affected by the street closure. Pedestrian access and access for essential services (such as emergency vehicles, mail delivery, and garbage pickup) will always be maintained. We are also working with our contractor to potentially address community concerns regarding the temporary street restoration conditions. Construction for the whole project is expected to be completed in fall 2023. See the yellow areas on the map for approximate work areas. All work will take place in the right-of-way.

Rendering of proposed Natural Drainage System cell design along NW 127th St Last month, the Natural Drainage System (NDS) project team held an on-site community meeting to answer your questions and showcase our 90% design plans for the project. Thank you to everyone who participated! It was great to see so many community members interested in the project, and we are working to address the questions and concerns that we heard. The presentation materials that we shared in the meeting, including maps and renderings, are now available in the project documents section of our website. The project team is finalizing the design. Stay tuned for more updates as we get closer to construction, which is expected to begin as soon as 2024. For questions about the NDS project, please contact Grace Manzano, project manager, at grace.manzano@seattle.gov. Looking ahead We will resume monthly email updates now that construction is restarting. Please encourage your neighbors to sign up by visiting our project website. Thank you!
