Fanno Trail closure until July 1

June 6, 2013

Environmental Services will close portions of the Fanno Trail starting Monday, June 10, 2013 to replace maintenance access structures in the Garden Home section of the Fanno Pressure Sewer. Parts of the trail will close from Monday, June 10 through Monday, July 1. Trail users will detour around the closure on neighborhood streets and on the path on SW Garden Home Road.

The trail closure will allow construction crews to access the pressure sewer at two locations, SW 82nd and 84th avenues, and replace three maintenance access structures that were damaged when the city activated the Fanno Basin Pump Station in November 2012. Environmental Services is installing a surge tank to relieve stress in the pipes and protect the pressure sewer when the pump station operates in the future. The surge tank will absorb pressure surges created when the pump station turns off and on.

The Fanno Basin Pump Station is currently not operating and sewage is flowing by gravity to a Clean Water Services sewage treatment facility. Environmental Services will activate the Fanno Basin Pump Station when work is finished on the maintenance structures and surge tank.

Environmental Services will begin construction this August on the SW 86th Avenue Pump Station near the Fanno Basin Pump Station to increase capacity and ensure that the system can handle all wastewater flows during large rain storms. The new pump station will operate year-round and the existing Fanno Basin Pump Station will operate only during wet weather to manage higher wastewater flows. Both facilities will be connected to the Fanno Pressure Sewer.

Environmental Services will replace several other maintenance access structures along the pressure sewer before activating the new SW 86th Avenue Pump Station in early 2016.
