We were contracted by the University of North Carolina at Chapel Hill to replace the stormwater system at the Botanical Garden Visitor Education Center.  To access the stormwater system we had to remove the entire garden area including beds, pathways and retaining walls.  We installed a new comprehensive stormwater system that incorporated elements that were asthetic as well as functional.  To add to the sustainable nature of the facility we constructed the retaining walls out of demolished concrete sidewalks.
