Gravel Roadway on Lakeview Boulevard through Summer

Lakeview Boulevard, between the Swim Park and Summit Drive, is a temporary gravel roadway through summer, as crews rebuild the road base and prepare for paving. Key information:

  • If you don’t need to drive or bike on Lakeview, please use alternate routes—this area will be rough, dusty, and under active construction all summer.
  • Reminder: Lakeview remains ONE-WAY eastbound ONLY between South Shore and Iron Mountain through summer. Going the wrong way is dangerous and illegal.

Wastewater Treatment Facility Project

Lake Oswego, with Portland’s support, has been using a phased project approach to replace the aging Tryon Creek plant with an environmentally sustainable wastewater treatment facility, at a good value to the community. The first phase of the project is now complete, which included developing facility designs, preliminary permitting, and proposed pricing for the Wastewater Treatment Facility Project.

For the second phase of the project, Lake Oswego will explore a competitive procurement method using public financing, to complete the design, construct the facility, and operate and maintain the facility under a long-term contract.
