APG prepared the consolidated land use applications required for the Sellwood Bridge Replacement Project. The land use applications included the following project components:

  • Temporary detour bridge (including in-water piers)
  • Replacement Sellwood Bridge (including in-water piers)
  • New Westside interchange with SW Macadam Avenue (OR 43)
  • Approximately one mile of improvements to OR 43 (including retaining walls)
  • Substantial improvements to pedestrian and bicycle facilities on and off the bridge, including extension of the regional multi-purpose trail from the replacement bridge north to Willamette Park
  • New stormwater facilities

The Type III Environmental/Greenway Review application was extremely complex and involved coordination with a large project team. The land use narrative was approximately 170 pages long and included hundreds of supporting plan sheets. The project area included seven different base zones and seven different overlay zones - including Greenway, Environmental, Scenic and Design Overlays. The project area encompassed hundreds of individual parcels, including four different Portland parks and natural areas.  

The project construction schedule was very aggressive and Multnomah County used the CM/GC delivery method instead of the design/bid/build approach. Land use permitting has been a key “critical path” item on the overall construction schedule. The land use permitting was segmented into two phases to provide the opportunity for the contractor to begin early in-water work associated with the detour bridge. 

APG’s role on the project required extensive coordination with Multnomah County staff, multiple Architecture/Engineering team members and multiple city of Portland bureaus. As a follow up to the land use decisions, APG also assumed a lead role in addressing compliance with conditions of land use permit approvals.
