Lower Bear Tributary Arroyo – Construction of a Water Quality Treatment Train in a Flood Conveyance Channel

presented by Patrick Chavez, PE (AMAFCA) and Sarah Ganley, PE (Bohannan Huston)

The City of Albuquerque and the Albuquerque Metropolitan Arroyo Flood Control Authority (AMAFCA) partnered to design and construct stormwater quality retrofit improvements within this flood conveyance channel that will function as a regional water quality facility. Bohannan Huston completed analysis, design, and construction inspection of the channel.

The existing channel had significant recurring erosion issues as well as urban pollution, leading to continual maintenance demands. Its location, upstream of a popular City park and the Bear Arroyo, makes this site ideal for innovative retrofit stormwater quality improvements.  This presentation will provide an overview of the project, the stormwater BMPs constructed and post-construction maintenance plans. Construction challenges, success, and lessons learned will be shared.
