The Last Impervious Surface in Portage County Ohio
The Last Impervious Surface in Portage County Ohio examines the disjuncture between material boundaries and political boundaries; using the Portage County Spillway - a 30-mile long, 500-foot wide, 5-foot tall asphalt megastructure spanning Portage County - as a lens. A topographical intervention, the Spillway is able to redirect enough rainfall towards Akron to support 100,000 people per year.
The Portage County Spillway was rehabilitated by the Great Lakes Architectural Expedition to create a continuous public space for the entire county. With integrated supergraphics to enable satellite monitoring of water flows, the Expedition spearheaded a ban on the construction of further impervious surfaces county-wide to ensure equitable access to fresh water on both sides of the boundary.
The transformation of the Portage County Spillway was an early success for the Great Lakes Architectural Expedition - acting to mitigate unequal water conservation practices, and establishing an obligation to serve the interests of the public realm defined by the Lake Erie Watershed and straddling counties and cities.
