Village at the Headwaters

Village at the Headwaters
Portland, Oregon

Village at the Headwaters is part of a large multi-family housing project and includes the daylighting of the headwaters of Tryon Creek. The headwaters and associated intermittent creek crossed the site and had been contained in a buried culvert in the creek’s filled ravine. The project included a water quality detention and infiltration facility to treat and retain stormwater and reconnect it to the Tryon Creek watershed. Past industrial use of the site was found to have impacted soil and groundwater.  GRI assisted the private/public development team with environmental cleanup during construction, and the site was remediated to levels protective of human health and the environment. GRI completed an Independent Cleanup Pathway under the Oregon Department of Environmental Quality’s Voluntary Cleanup Program leading to a No Further Action status for the site. In addition to the environmental services, GRI provided geotechnical recommendations for design and construction of the residential development.
