Mark Hanna to Present at Los Angeles River Watershed Research Symposium Release Date: 02/26/13
Mark Hanna, Ph.D., P.E., a senior water resources engineer and an Associate of the firm based in California, will present an overview of Geosyntec's efforts to revitalize portions of the Los Angeles River watershed during a symposium set for March 8.
The event, "The Restoration and Development Challenges of the Los Angeles River," is sponsored by the Council for Watershed Health and will be held 8 a.m. until noon at CBS Studios, 4024 Radford Avenue in Studio City. Pre-registration is required.
Dr. Hanna will discuss the technical and political processes he has encountered while supporting the development of two, very far-reaching projects on the banks of the Los Angeles River — Siempre Agua and Piggyback Yard.
The Siempre Agua and LA Noria project — an innovative, public-private partnership led by Metabolic Studio, will create the first Los Angeles River Water Wheel in more than 150 years. The project entails the design and construction of a diversion from the channel of the Los Angeles River through a tunnel to direct the flow to a water wheel, called LA Noria.
This project, the first to remove concrete from the channel walls of the Los Angeles River, will allow for diversion of significant flows from the river itself. Scheduled to break ground later this year, Siempre Agua will bend the Los Angeles River and deliver water to a planned wetlands area for beneficial use at the nearby Los Angeles State Historic Park.
Dr. Hanna also will discuss the status of the Piggyback Yard feasibility study. For this project, Geosyntec performed hydraulic analyses necessary to conceptualize the removal of more than 2,000 linear feet of channel wall, along with water quality and preliminary geomorphic analyses. Once implemented, the project could allow for inundation of up 60% of the 125-acre Mission Yard next to the Los Angeles River.
The Council for Watershed Health is Southern California's center for watershed research and analysis. Its mission is to facilitate an inclusive consensus process that enhances the economic, social, and ecological health of the region's watersheds through education, research, and planning.
