The Sellwood Multi-Modal Center (SMMC) will complement the Sellwood Bridge Replacement Project located in Portland, Oregon. Multnomah County, the client, and David Evans & Associates, the consultant, have identified five possible sites for the Sellwood Multi-Modal Center. The following report describes the analysis and selection of site alternatives for the SMMC by CHANGE Engineering Services. Through this analysis CHANGE Engineering Services concludes that Site 5, DR South, is the most suitable location for the SMMC. Building on Site 5 will ultimately save construction costs, provide better circulation of traffic, decrease the projected design schedule, and best comply with LEED and ASCE sustainability metrics. Furthermore, the location satisfies social considerations such as bicycle and pedestrian access, community values, and anticipated use of the facility.
