Return to Surface Water
A Watershed Moment
When the ribbon was cut on the Rocky Branch project, the stream that flowed through the heart of North Carolina State University was restored, but the university was transformed. Thirty years ago, Rocky Branch was given the dubious distinction of being the “most polluted stream” in the state of North Carolina. Today, it’s a model of restoration practices for the region. Before the restoration, the rain that fell during storms was considered a problem. The university’s management strategy was to get the rain off campus as quickly as possible. After the restoration, however, facilities management had a new appreciation for the rain that fell on campus. Watch as a university rises to the challenge of caring for the water that cycles through campus. This video is part of the Surface Water series.
- Imagine you are a civil engineer with earth-moving equipment. How would you restore a stream?
- Imagine you’re a landscape architect. How would you design a rain garden?
- Why has rain traditionally been a problem for cities?
- How did the university manage streams in the past?
- What methods did the university use to restore Rocky Branch Creek?
- How were university organizations and students involved in the restoration of the area between the dorms?
- What methods are now used to collect rainwater?
- Why do you think the stream restoration changed the way the university handles stormwater?
- Design a rain garden for your school.
