My history | My motivations | Local, regional, national + international relevance
In the 1960’s, citizens became increasingly upset regarding the sewage stench from Sugar and Little Sugar Creeks in Charlotte. In response to numerous citizen complaints, the Mecklenburg County Health Department hung 55 gallon drums of orange blossom deodorant from bridges and allowed the fragrant liquid to drip into creeks to mask the odors. This effort proved unsuccessful. Water quality problems came to head in the late 1960’s.

Problems that exists at many scales require solutions that exist in multiple scales.

public space
There is little open public space along this corridor here. Privately owned spaces are back, away from the street. Can the street become more vibrant with publicspaces more visibly on the street?

Public space functions in commercial and entertainment purposes. Water visibility adds a layer of environmental education and awareness.
Parking deck water collection and movement corresponds with public space. The movement of the water shapes the place.
Water is collected and brought to the bioswales, watering the trees along the way.
Roof collection - conveyance to the street
Water flow
Varied facade that channels, directs, collects
Water conveyance becomes entries, seating, and bus shelters

Can down spoutsmorph into sittable spaces or mailboxes?
Sidewalk Cistern
Visibility and uncovering our infrastructure is a primary goal.
The facade throws water into the right place while sidewalk cisterns frame public space, acting in rhythm and public art, cluing people into their environment.

Questions | How do we get these integrated solutions implemented?
What are the challenges to implementing these kinds of stratgies on the local level?
- political? - policies and regulations?- funding?- health and safety?
How can we overcome these challenges? What can we do today to get closer to implementing integrated solutions?
