Headwaters at Tryon Creek – Portland, Oregon

Headwaters at Tryon Creek

GreenWorks provided landscape architecture services in master planning a new 2.7 acre mixed – residential development near the headwaters of Tryon Creek in southwest Portland. The project includes a variety of residential types including elderly housing, town homes, and a PDC low-income apartment building. All of the new residential developments were designed to be integrated with the daylighting of a tributary of Tryon Creek. A grant was received by the Oregon Watershed Enhancement Board to help with the stream daylighting costs. The development was coordinated with many local agencies (Portland Development Commission, Housing Authority of Portland, Portland Bureau of Transportation, Portland Parks and Recreation, and Bureau of Environmental Services) to extend the daylighting project from the headwaters of the tributary in a park upstream from the site, through the site and into the adjacent downstream neighborhood to Tryon Creek. The goal of the developer and the design team was to integrate the buildings, parking areas, plazas, bridges, pathways and other site elements into a cohesive sustainable site development that takes full advantage of this wonderful daylighting opportunity. “Green development” site features, included: porous pavement in parking lots; flow-through planters for managing roof and pavement runoff; greenroofs; and Green Street solutions (infiltration planters for street runoff). Green Street solutions were applied to SW Marigold Street, SW 30th Avenue and SW Dolph Street. GreenWorks services include schematic design, design development, construction documentation, and services during construction.
