In July 2012 the Quail Fire started on the east bench of Alpine City and burned a large area of the watershed encompassing Box Elder and Wadsworth Canyons. Burning of the ground cover significantly increased the runoff potential in these two watersheds and the potential for flooding debris flows. Alpine City and Bowen Collins & Associates (BC&A) worked together to identify four sites that would require repair/mitigation measures to protect homes and other infrastructure below the burned area.
Multiple restoration, grade control, and bank stabilization projects were implemented to mitigate the potential for flood and debris flow damage after the Quail Fire. These projects included: construction of several drop structures, two debris basins, a concrete flood wall and a debris rack, channel repairs and bank stabilization, installation of various erosion control measures and vegetative restoration.
The project was featured in the new on Fox 13 and can be viewed by clicking the link below. Although there were other areas of flooding in Alpine, BC&A’s design stood up to both July storm events.
