The Clarifier Landscape and PGE Dam Promenade 
 A proposed walkway rings the clarifier, a water quality treatment structure once used by Blue Heron Paper to treat waste water from its paper making processes. The landscape interior of the clarifier is inspired by the region’s oak savanna habitat featuring characteristic Oregon oak and camas plantings as well as basalt salvaged from the site.
