CONSTRUCTION INFORMATION - COMBINED SEWER OVERFLOW / PHASE 1
CSO Information  | Construction Information | FAQs

OVERVIEW
The Project extends from downtown Port Angeles, along the waterfront and the Olympic Discovery Trail, through the former Rayonier mill site, to the City's Wastewater Treatment Plant (WWTP), a distance of about 1.7 miles.

The City of Port Angeles has contracted with IMCO General Construction from Ferndale, Washington for the Combined Sewer Overflow (CSO) Phase 1 project.

The CSO Phase 1 Project is the first phase of two projects in the Capital Facilities Program.

____________________________________________

The Phase 1 construction project will increase the size of the sewer force main (primary interceptor) between the downtown and the wastewater treatment plant. The current interceptor is too small to handle peak flows during wet weather. It is located along the shoreline and in some places in the harbor.

Figuratively, it is the main artery of this system, connecting all other wastewater pipes to the plant. By eliminating this bottleneck in the system, much of the CSO problem will be corrected.

The new interceptor pipes will cross Ennis Creek on a bridge that has been sited to facilitate future Creek restoration projects. When the project is complete, the Olympic Discovery Trail will be improved, and will cross over the new bridge.

In addition, the wastewater treatment plant will have some internal bottlenecks remedied, which will increase the capacity of the plant.

During the heaviest rain events, the wastewater treatment plant will not be able to treat all the flow as it arrives. At those times, excess flow will be pumped to a 5 million gallon storage tank that will be retrofitted as part of the CSO Phase 1 project. This tank will be gradually drained into the plant during times when flows will permit it.

In addition, the old Rayonier industrial outfall will be retrofitted and placed into service as the City's primary wastewater treatment plant outfall. This outfall is larger, longer, and deeper than the City's existing outfall and will diffuse treated wastewater more effectively and in a location farther away from the Port Angeles harbor.

CSO CONSTRUCTION / DETOURS / STREET and TRAIL CLOSURES
Street and the Waterfront/Olympic Discovery Trail closures and detours.

STREET CLOSURES & DETOURS
Posted March 4, 2013 - Oak Street between Railroad Avenue to Front Street reopened two weeks earlier than anticipated. Vehicles will be able to access businesses and parking lots from Front Street.  Parking will be available on the east side of Oak Street (No parking will be allowed on the west side of Oak Street). The sidewalk on the west side of Oak Street will remain closed.  Pedestrians can use the east sidewalk to access businesses. The road is currently gravel, therefore motorists should use extreme caution.

Railroad Avenue between Oak Street and Laurel Street will be closed during the project. At times, construction will require partial and often sustained closures along certain sections of the Waterfront Trail and some streets. Detours will be in place when safe and practical.

Thank you for your patience. Businesses in the area remain open.

UPDATES ABOUT TRAIL CLOSURES & DETOURS
Posted May 3, 2013 - The Waterfront Trail has been reopened to its original configuration for public access between the City Pier and the Waste Water Treatment Plant.   The trail has been detoured since October 15, 2012 while crews worked on the CSO Phase 1 Project.

Francis Street Park will remain closed and is expected to be reopen by June 14, 2013.

DETOUR - A trail detour is available around the Rayonier Mill Site, connecting to Ennis, then to Georgiana, Front Street, Lincoln Street and then reconnecting back to the Trail on Railroad Avenue.
