Saturating the Built Environment: Infusing Stormwater and the Public Realm

Urban Designer / Planner / Architect-in-training keihly.moore@thelawrencegroup.com


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. http://charmeck.org/stormwater/VolunteerGetInvolved/Documents/ Fun%20and%20Facts%20PDF/HistoryofWaterinOurCommunity.pdf

Buildings: interaction with the ground/water

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

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 public spaces more visibly on the street? privately owned outdoor public space public space

Phase 1: Parking lot retrofit


Public space functions in commercial and entertainment purposes. Water visibility adds a layer of environmental education and awareness.

Water is collected and brought to the bioswales, watering the trees along the way.

Parking deck water collection and movement corresponds with public space. The movement of the water shapes the place.

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? Would you like to chat further? Keihly.moore@thelawrencegroup.com Questions | How do we get these integrated solutions implemented?
