Dammed: Master Planning Along the Lower Snake River in a Post Dam-Removal Condition

Abstract

The four dams on the lower Snake River in Washington state have numerous impacts on the surrounding environment, and although provide benefits of hydroelectric power, irrigation services, and waterway navigation that alter the state of the river and adjacent land ecologically. The question that persists is if these structures need to be maintained, replaced, or removed altogether; since like all man-made structures, they have a finite lifespan that is approaching its end. The following research and methodologies address design solutions for these dam sites in a post-removal condition through case studies, site analysis, site planning, and design interventions from a landscape architectural lens. Although total removal is not certain as it deals with the influence of many different stakeholders, for the approach it will err on the hypothesis of removal. The unique design approach will open the door for greater opportunities along the river corridor.
