Cleaning, filling, testing and disinfecting the new filters

Miscellaneous piping work

Crews continue installing yard piping across the site. This week they are by the chemical building. Work involves excavating, placing pipe, and backfilling the trench.

Site improvements underway

Curb and gutter replacement work is underway along the Kenthorpe Way frontage of the plant (pictured right). During this work, no parking is permitted during work hours on the south side of Kenthorpe Way, along the plant frontage. This morning, crews poured the curb to the west of the plant entrance. This work is expected to be complete next week. Neighbors in this area should expect intermittent single lane closures during this work and an increase in noise.

The foundation for the new site walls has been poured in the south west corner of the site by the electrical building, and will soon be poured near the construction trailers. Crews will then move to the landscaping improvements and rain garden to be installed near the main entrance of the plant on Kenthorpe Way. This work includes excavators digging and preparing the site, placement of materials, forming hardscaping and backfilling/compacting fill. During this work, neighbors close to the site should expect some noise and vibration from the movement of the equipment.

Tree removal at the end of Kenthorpe Way

This work has been rescheduled and is now expected to begin next week. Trees and vegetation located in the public right-of-way at the east end of Kenthorpe Way, adjacent to the eastern boundary of the plant site, will be removed. This is to enable the installation of the sidewalk that will be located at the end of Kenthorpe Way, which will join the new pedestrian pathway to be installed on the eastern portion of the plant site. These trees have been approved for removal by the City of West Linn.

Neighbors can expect to see crews of workers, trucks and equipment. Tree and vegetation removal is expected to take about a week to complete. During work hours, there will be a single lane closure to accommodate equipment. Neighbors should expect to hear an increase in noise from chain saws operating.

Great progress is being made on cleaning, filling, testing and disinfecting the new filters (pictured above). Over the next few weeks, the new filters are expected to be operational!
