Traffic delays on SW Multnomah Boulevard

April 8, 2010

A City of Portland contractor is excavating today and tomorrow at seven locations in Multnomah Boulevard between SW 34th and SW 58th avenues. Motorists and bicyclists should expect intermittent lane closures and traffic delays during construction hours, 8:00 a.m. to 4:00 p.m. on Thursday, April 8 and Friday, April 9. Flaggers are assisting traffic around construction equipment.

The excavations will locate underground utilities in advance of sewer pipeline construction in Multnomah Boulevard, which is tentatively scheduled to begin the week of April 19.


City offers ecoroof incentives

April 13, 2010

More incentives to install new ecoroofs in Portland are available from the city’s Bureau of Environmental Services. The ecoroof incentive program is part of Portland’s Grey to Green effort to increase Portland’s green stormwater management infrastructure, protect sensitive natural areas and improve habitat.

The incentive pays up to $5 per square foot for new ecoroof projects in the city. Ecoroofs in Portland typically cost between $5 and $20 per square foot. Industrial, residential, commercial and mixed-use projects are eligible for the incentive.

The city has begun a new cycle of ecoroof incentives and is accepting applications through Tuesday, June 1, 2010. Environmental Services will award incentives this summer. The city will continue to make funds available until 2013

The ecoroof incentive application packet is available at or by calling 503-823-7914.

Ecoroofs are vegetated roof systems that reduce stormwater runoff, improve air quality and save energy. The Grey to Green goal is to add 43 acres of new ecoroofs by 2013. Since the initiative began in July 2008, more than four acres of ecoroof have been completed and over six acres are in design or construction. There are currently 211 ecoroofs in Portland covering nearly 11 acres.

Tunnel boring machine demonstration

April 20, 2010

A micro-tunnel boring machine manufactured to construct the Balch Consolidation Conduit is about to go to work. Tomorrow, the project team will give a public demonstration of how the machine will construct about 7,000 feet of 84-inch pipeline.

Who: Balch Consolidation Conduit Project team

What: Micro-tunnel boring machine demonstration

When: Wednesday, April 21, 2010, 10:30 a.m.

Where: NW 29th and Industrial - from NW Yeon, go south on NW 35th, east on NW Guam, and south on 29th to NW Industrial, watch for event parking signs

The Balch Consolidation Conduit is part of Portland’s 20-year program to control combined sewer overflows (CSOs). The pipeline will carry combined sewage and stormwater runoff from the Balch Drainage Basin to the West Side Big Pipe for conveyance to the Columbia Boulevard Wastewater Treatment Plant. Construction began in June 2009 and will be complete by December 2011.

The city’s Balch Consolidation Conduit contractor, James W. Fowler Co., will use the micro-tunnel boring machine to install most of the 8,500 feet of pipeline at depths ranging from 20 to 70 feet.
