June Water Quality Trivia

Answer: B

Approximately 25,000 customer samples have been analyzed for lead in water through the Water Bureau’s testing program. While all known sources of lead have been removed from the Water Bureau’s distribution system, customers can be exposed to lead through their home plumbing.

DATE CHANGE - Council Final Decision on Proposed Washington Park Reservoir Project Type IV Land Use Review Application Rescheduled for June 25

Add a Comment

In order to comply with federal and state mandates, and ensure a healthy, resilient, and secure water system, the Portland Water Bureau is moving forward with a project to update the Washington Park reservoir site in southwest Portland.

On May 13, the Portland City Council gave unanimous tentative approval on the Portland Water Bureau’s Washington Park Reservoir Improvements Project Type IV Land Use Review (LUR) application.

The City Council will make a final decision on the Type IV Land Use Review (LUR) application on Thursday, June 25 at 2 p.m. in City Hall Council Chambers at 1221 SW 4th Avenue.

The final decision was rescheduled from Wednesday, June 10.

Members of the public are welcome to attend. However, no public testimony will be heard as the public comment and testimony period closed on May 7. Opportunity for public input included the Historic Landmarks Commission meeting in March 2015 and the City Council hearing in April 2015.

The initial Type IV LUR application proposes the removal of the Weir Building (screen house), portions of lower Reservoir 4’s basin, and upper Reservoir 3’s basin in Washington Park. The gatehouses, dams, and other historic features will be protected and restored.

Proposed Project
The Water Bureau’s Washington Park Reservoir Improvements Project proposes to build a new below-ground reservoir in the same general footprint as the existing upper Reservoir 3, with a reflecting pool on top.

The lower Reservoir 4 will be disconnected from the public drinking water system and a lowland habitat area/bioswale and a reflecting pool will be constructed in the basin. Much of the Reservoir 4 basin and the slope to the west are needed to provide landslide abatement; the slope will be restored to its pre-reservoir condition.

The new below-ground reservoir in the place of Reservoir 3 will be constructed so that it is outside of the moving edge of the landslide, which will help protect it from damage.

The project addresses major reservoir issues, including recurrent landslide damage, compliance with federal law, seismic vulnerability, and deterioration of the 120-year-old structures.


  • In December 2014, the Water Bureau submitted the first (Type IV) of three LUR applications to the City of Portland Bureau of Development Services (BDS) for the proposed Washington Park Reservoir Project.
  • On February 9, BDS deemed the Type IV LUR application complete, issued a Request for Response, and officially opened the public comment period and set the dates for the Historic Landmarks Commission meeting and the first City Council Hearing.
  • On March 30, a public meeting was held before the Historic Landmarks Commission to review the Type IV LUR application. During the public meeting, BDS presented the Staff Report and Recommendation, the Water Bureau discussed the project, and members of the public offered testimony. The Commission voted 3 to 1 in support of the initial LUR application and forwarded their recommendation to the City Council.
  • On April 23, the first of three City Council hearings was held. During the hearing, members of the public had the opportunity to offer testimony. At the hearing’s conclusion, the City Council agreed to allow the record to remain open through May 7.
  • On May 13, City Council held a second hearing for the purpose of deliberations on the application. The record had previously been closed, and no testimony was accepted. After deliberating, Mayor Charlie Hales and the City Council gave unanimous tentative approval to the Type IV LUR application.  
  • The next step will be a final decision by the Mayor and Council at a hearing on Thursday, June 25 (rescheduled from Wednesday, June 10).

Type III LUR Application Package
In spring 2015, the Water Bureau will submit a second LUR application package that includes two Type III applications: 

The LUR package will propose the construction of a new covered reservoir, reflecting pools, lowland habitat area/bioswale, walkways, and historic preservation and rehabilitation actions. The second LUR application process will also include public comment periods and public hearings to ensure public notification and the opportunity to comment before a final land use decision is rendered.

Before work permits are issued or construction begins, all three LUR applications must be approved.

The LUR applications are a result of a robust public involvement process that included multiple public open houses, nine Community Sounding Board meetings that guided design for the required visible features of a new reservoir in Washington Park, five public meetings before the Historic Landmarks Commission, and three City Council hearings.

Powell Butte Reservoir Piping Flow Meter Testing Scheduled for June 9

Add a Comment

On the morning of Tuesday, June 9, the Powell Butte Reservoir 2 contractor will conduct a test of two ultrasonic flow meters located in piping associated with the underground Reservoirs at Powell Butte Nature Park in Southeast Portland. 

The four hour test will consist of Water Bureau operating engineers slowly draining approximately 72,000 gallons of de-chlorinated water at 300-gallons per minute from a 54-inch discharge pipe through the meters and then into Johnson Creek.

The test will confirm the meters are accurately measuring water flowing through the pipe and are able to monitor future discharges.

Water Bureau representatives will be on site at Powell Butte throughout the entire duration of the test to supervise and monitor the operation.

The flowrate, temperature, and PH of all water discharged to Johnson Creek will be closely monitored to ensure compliance with all applicable environmental and regulatory requirements. 

For questions about the operation, please contact Lindsay Wochnick, Public Information, at 503-823-3028 or by e-mail
