Columbia Building

John Grade art installationEnvironmental Services completed construction of the Columbia Building in fall 2013 and wastewater engineering and construction staff finished moving into the new space in January 2014. The staff provides project management, engineering design services, and construction management for wastewater treatment and collection system projects.

The new structure integrates with the plant campus, creates a more welcoming public entrance, demonstrates sustainable practices, and fulfills the need for more site security.

Columbia Building construction was part of a larger treatment plant improvement project.

Project Features

  • The building is a LEED Gold Certified structure, demonstrates sustainable practices through its design and will serve the plant for at least 100-years.
  • Site redevelopment included a new plant entrance, pond restoration, parking lot upgrade, and landscaping impacting more than three acres.
  • Meeting spaces in the new building will be available for rental to the public in spring 2014.
  • The building’s green roof and other stormwater facilities manage stormwater runoff on-site.
  • The landscaping uses plants native to the Columbia Slough watershed.
  • Reconfigured parking areas have new stormwater management facilities and electric charging stations.
  • Through Portland’s Percent for Art Program, an installation by artist John Grade complements the facility design and welcomes visitors and staff.
