SW Main Street Improvement Project, Phase 2

Tigard, OR


The City of Tigard chose Century West to provide the engineering design for the reconstruction of SW Main Street, an 800-linear-foot downtown collector, from the railroad tracks north to Scoffins Street to create a vibrant downtown that connects the community, visitors, and businesses. The design package required traffic analysis; site investigations; grading and roadway design; signage and striping; illumination and electrical work; stormwater design; water main layout; and landscaping and irrigation design. Century West led coordination efforts with Genesee & Wyoming Railroad, ODOT Rail, and TriMet to permit work within the rail crossing envelope, with TriMet for bus stop consolidation efforts, and local franchise utilities to inventory, pothole, and relocate their facilities prior to construction. Century West also aided the City in stakeholder and public outreach during design and construction. The project was recently bid at $3.27M and achieved substantial completion, with the anticipated final cost at $3.34M.

The project improvements, intended to be pedestrian and environmentally friendly, include the following elements:

  • Full pavement and sidewalk reconstruction
  • Sidewalk amenities, street furniture, art pedestals, and pedestrian-scale lighting upgrades to enhance the pedestrian experience and safety
  • LIDA stormwater planters, street trees, and landscaping for stormwater management and the beautification of Main Street
  • Replacement of existing water mains, including meter services and fire hydrants
  • Consolidation of multiple existing bus stops to provide mid-block locations with greater visibility, larger shelters, in-lane impact slabs, and dedicated loading zones
  • Enhanced pedestrian crosswalks and a mid-block rectangular rapid flashing beacon crosswalk connecting the new bus stop plazas
  • Addition and upgrade of numerous existing curb ramps, building door landings, loading zones, etc. to meet ADA standards
  • Basin analysis and upsizing/relocation of the existing undersized storm main.
