West Linn Staff Recommends Land Use Approval

West Linn Staff Recommends Land Use Approval

The City of West Linn Planning Commission will hold its first public hearing on the Partnership's Water Treatment Plant expansion and upgrade at a meeting of the Planning Commission this Wednesday night.  West Linn’s staff found “sufficient grounds for approval” of the Partnership’s plans with several conditional requirements.  The Partnership is supportive of the staff decision.

“The proposal includes sustainable development techniques, such as green street design, permeable surfaces, green roofs, compact site design, and minimal driveways. The upgraded facility is expected to be safer and more efficient than the current one due to modernization of the operations utilizing the latest technologies and compliance with the current codes from outside agencies.”

Upcoming meeting:
West Linn Planning Commission
Wednesday, April 18th at 7:30pm

Materials for the upcoming Planning Commission meeting, including the staff report, can be found on the City of West Linn’s website.
