The City of Austin retained Geosyntec to stabilize approximately 450 linear feet of eroding stream bank along lower Buttermilk Creek to protect a threatened multi-family structure and to rehabilitate and restore riparian habitat along adjacent portions of the stream channel. Urbanization and increased impervious cover in the contributing watershed of the stream has resulted in increased volume and frequency of storm runoff and stream flow, which in turn led to stream erosion. The eroding stream bank undermined an existing storm drain and fence, and was threatening other infrastructure. The project objective was to design and implement engineering solutions to stabilize the existing stream bank, protect threatened infrastructure, restore native vegetation along the creek corridor, and preserve existing aquatic habitat.
