On April 4 2023, the City extended a contract with EPCOR Foothills Water Project to advance project designs from a 60% level to a 90% level. In late fall 2022, the 60% design concepts were shared through an online open house.

In the coming months, the project team plans to apply for a development review permit application with the City of Lake Oswego. Prior to this, the project team will hold a supplemental neighborhood meeting with the community to discuss the proposal in more detail. This is planned for late June. More details will be shared shortly. 

On Tuesday, April 4, 2023 at 5:30 p.m., Lake Oswego City Council will consider approving an amendment to extend the Preliminary Services Agreement with EPCOR Foothills Water Project for a period of up to 12 months. During this period, EFWP will advance project designs from a 60% level to a 90% level.

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 would be expected in early 2024.

Here is a link to the council report and the agenda. You can view this meeting livestreamed on the City’s YouTube channel.

On Tuesday, December 20, 2022, at 3 p.m., Lake Oswego City Council will consider approving a Resolution to Declare a Public Necessity, an amendment to the Interim IGA with Portland, and additional consulting spending regarding the Wastewater Treatment Facility Project. The Resolution of Necessity describes the land to be acquired for the new facility and the public interest in acquiring the land. The Resolution would authorize the City to move forward with property acquisition and relocation of existing businesses by commencing he eminent domain process needed for building the new facility.
