Velocity’s Lapse This proposal asks how we might redirect cultural momentum and revise existing infrastructure towards beneficial action. If real sustainability can only be achieved when it becomes a public priority, then this proposal asks how architecture can be the catalysis. How can we reshape the collective identity of a city to promote respectful, considerate relationships between urban processes and the natural environment? Purification The primary objective of the site is to clean the city’s contaminated storm water, before releasing it into the Willamette River. 12 300 ft2 Water Treatment. 350 000 gallon Water Storage Bio-Clear packaged treatment plant by Ecologix Environmental Systems: EQ tank, sludge holding tank, aeration basin, clarifier, clearwell, UV disinfection.
Percolate The city connects with the river in sheltered food markets and artist spaces. Unconditioned spaces save energy while prompting a more natural connection to the river and surrounding landscape. 1 500 ft2 Public Event Space 10 300 ft2 Food Markets 5 900 ft2 Artist Space + Administration
Confluence Extensive riparian restoration demonstrates an ecological sensitivity, providing habitat for native flora and fauna. The rivers edge becomes an abrupt departure from the urban landscape, available to those seeking a connection to the river. 115 000 ft2 Riparian Restoration, Boardwalk, Public Space, River Access
Existing Conditions The Eugene Water and Electric Board is relocating their facilities, creating an opportunity for downtown Eugene to connect to the Willamette River. It is currently a 27.8 acre brownfield site, housing what can potentially be a handful of historic buildings.
Master Plan Through an extensive community design process, a master plan was created to inform future development on the site. It divides the land between new public open space, new development, adaptive reuse, green streets, and bike/pedestrian paths. Currently running through the site is a pipe carrying much of Eugene's polluted stormwater directly to the Willamette River.
Urban Runoff Intervention The exiting stormwater is interc filtration sequence to clean the before it is released in a riparia river. This underground channe accessible to expose this envir process in a meaningful way.

Site Stormwater Management Storage tanks collect run-off from the site's impermeable streets before it can be cleaned by the channelized filtration system. The rainwater from the street's 120,000 ft2 area is accommodated by a total volume of 350,000 gallons. As the frequency of rain becomes lessened in the summer, these storage volumes are drained to become rooms that house pop-up art galleries.
Bridging City and River A series of covered pavilions bridging the channel of water seek to connect the city and the river. These shelters offer rentable space for small food vendors, as well as artists, creating a variety of destinations. These unconditioned spaces save energy while prompting a more natural connection to the river and surrounding landscape.

Covered Pavilions As an homage to Oregon's covered bridges, a series of covered pavilions support a variety of community needs, and bridge the City of Eugene with the Willamette River.
Subterranean Water Treatment An underground water filtration channel is bordered by undulating paths, allowing visitors to experience the cleansing process. The dark descent leads to bright and pristine wetlands, supporting the river’s ecology and providing opportunities for swimming.
Water Marks Oil and sediment embed on the walls of rainwater collection rooms, documenting annual rain levels and after many years revealing the effects of climate change on rain water.
