Water Treatment Plant Construction Update

It’s been a while since we’ve updated neighbors about work at the water treatment plant, so please read on for the latest news.

Work Hours

Due to the excessive heat wave upon us, the landscapers plan to start work an hour earlier each day for the next two weeks (6 a.m. to 7 p.m., Monday to Friday, 8 a.m. to 5 p.m. on Saturdays). Work will involve the use of small equipment already on site to pick up and place trees and hand work for planting shrubs etc. Any large landscaping trucks will access the site after 7 a.m.

This early start time has been approved by West Linn’s City Manager.
