Here is a summary of the work happening in Public Works. Please feel free to contact Marissa Grass, community engagement coordinator, with any questions.
Big Construction Projects Wrapping Up
Wall Street Improvement Project: Construction on a key infrastructure project is now complete. Phase one of the Wall Street Improvement Project converted Wall Street from a two-lane private drive into a fully functioning public street with sidewalks and utilities.
Ultimately, this project will complete a road connection for freight and commercial vehicles to route around the overloaded Hunziker Street/72nd Avenue and Hwy 217 intersections in Tigard. Phase two of the project will continue the Wall Street connection to Tech Center Drive (this phase is slated to start in the summer of 2020). The improved Wall Street connection should also help ease traffic for commuters by moving commercial vehicles off overloaded streets.
Project Manager Andrew Newbury reports excitement about one of the cost saving measures implemented in this project, “Instead of using a typical rock base underneath the asphalt, a cement treated base was used. This is where cement and water are mixed into the existing soil. This results in a very hard surface and allows pavement to be placed directly on top. This saved approximately $300,000.”

Tiedeman Avenue: Trail users are celebrating the reopening of Fanno Creek Trail in Woodard Park. This project completed a missing link of the Fanno Creek Greenway Trail. Construction of a new bridge and trail segment provides an accessible route where it did not exist before. This section of the trail was previously a barrier to many users. As part of the project, the trail was realigned to increase safety by crossing Tiedeman Avenue at an established crosswalk. It also provides clear definition of the regional trail route so that trail users can easily find their way.
Upcoming projects at this location include safety changes at the crosswalk, adding refuge islands and more visible lighting. A new mural will also be painted on the retaining wall and bridge foundations to add character to the trail and to help discourage graffiti.
Most of the project was paid for with a generous $800,000 grant from Metro.
Fanno Creek Remeander: Construction is substantially complete on the Fanno Creek Trail remeander project between Main Street and Ash Avenue. The project is designed to reduce erosion, increase water quality, allow better flood passage, and create a safety corridor for pedestrians.
Construction, which began and ended in the summer of 2018, involved excavating a new channel, filling the old one, replacing the pedestrian bridge, and putting in place short-term approaches to stabilize the streambanks for the winter between construction and revegetation. For example, some of the streambanks were constructed of soil lifts: Layers of soil wrapped in coconut fiber blankets, with dogwood branches placed horizontally between them. In the spring of 2019, revegetation will begin.

Investing in Our Water System: Waterline Replacement along Commercial Street
The City of Tigard maintains approximately 250 miles of pipelines that deliver safe, clean drinking water to homes and business. Every year we invest in replacing aging pipelines to keep our water system operating smoothly. When we can, we “piggyback” our replacements on roadway improvement projects, reducing the cost and providing new pipelines that work better with the improved roadways. Our cost saving approach to replacing pipelines in coordination with other Public Works construction projects is part of our commitment to maintaining affordability for customers.
Up next is waterline replacement along Commercial Street. Beginning the week of January 22, the water division will be working on SW Commercial Street between Lincoln Avenue and Main Street. This work is scheduled to be complete by February 25, 2019. Traffic delays can be expected on Main Street, including a detour around the construction site. Access will be maintained to the Park Glen Apartments on Commercial Street.
