Recent Online Open House

Thank you to the more than 480 people who recently engaged with our online open house sharing the 60% design concepts! The open house was available from November 9 through December 11. It featured videos, renderings, a virtual tour, graphics, frequently asked questions, and a survey about the proposed new facility.

20 people completed the survey, and the majority of those identified as interested community members.

A link to the open house summary and survey results can be found here.

The cities of Lake Oswego and Portland are preparing to extend the Preliminary Services Agreement (PSA) with EPCOR Foothills Water Partners (EFWP) for a period of up to 12 months. During this period, EFWP will advance project designs from a 60% level to a 90% level. This also allows more time for securing all necessary permits and purchasing properties for the new facility.

Lake Oswego City Council will consider approving the PSA extension at their regular meeting on December 20, 2022.

A final decision by the Council on whether Lake Oswego will enter into a long-term Public-Private-Partnership (P3) project agreement with EFWP for the construction, financing, operation, and maintenance of the new facility is now expected in late 2023.

For more information on the delivery process and expected timeline, please review the FAQs on the project website.
