Foster Floodplain Natural Area

Location: Portland, OR
Client: City of Portland, Bureau of Environmental Services

The East Lents Floodplain Restoration project was an aggressive undertaking by the City of Portland’s Bureau of Environmental Services to reduce flooding by Johnson Creek in the Lents Neighborhood and restore natural watershed functions. Over a period of 15 years the City acquired 52 acres of former residential lands in the floodplain that were restored to public open space. Construction began in 2010 with removal of the remaining residential structures and salvage of on-site trees. Work to deconstruct bridges, roadways and utility infrastructure; excavate flood storage; rehabilitate stream banks; add habitat structures; retrofit stormwater outfalls for water quality, as well as construct new roadways, utilities, sidewalks and public access amenities was completed in two phases during the 2011 and 2012 construction seasons. The City removed and replanted the entire site in 2013, and the site, renamed the Foster Floodplain Natural Area, is open to the public and maintained by the Portland Parks Bureau.
