Geosyntec Celebrates Opening of the Argo Drain Sub-basin Facility for the City of Los Angeles

Geosyntec's Christopher Wessel, P.E., QSD/QSP (California) and Chris Conkle, P.E., G.E. (California), attended the grand opening of Argo Drain Sub-basin Facility in Marina Del Rey, California on June 17, 2021.

The $35.8 million stormwater project, which included planning, design, and construction contributions by Geosyntec for the City of Los Angeles, captures stormwater from the Los Angeles International Airport area, removes debris and trash, and pretreats it before infiltrating it into the underlying soil and groundwater. The project was designed to meet a number of applicable water quality regulations, thereby helping to protect public health while keeping Santa Monica Bay clean. In addition, it will support future use of the area as a green space.

The new facility addresses Los Angeles Mayor Eric Garcetti's concern about allowing stormwater to run off into the ocean, "We must clean it, we must capture it and we must put it to good use." Geosyntec's project with the City of Los Angeles does just that.

The project illustrates "a portfolio approach to stormwater management," says Ken Susilo, P.E., D.WRE, and Manager of California Water Resources. "The Argo project is an example of how a regional facility can be optimized for cost, technical efficiency, and space. Design development used a unique linkage of continuous hydrologic scenarios, optimized through varying numerous infrastructure components."

Those who spoke at the event included LA Councilman Mike Bonin; Greg Good, President of the City of Los Angeles Board of Public Works; Jessica M. Caloza, a Commissioner on the Board of Public Works; Justin Erbacci, CEO for Los Angeles World Airports; Gary Lee Moore, City Engineer; John L. Reamer, Jr. Inspector of Public Works; and Shahram Kharaghani, Los Angeles Sanitation Stormwater Program Manager.

Geosyntec is also leading the San Fernando Valley Green Streets Network, Progressive Design Build and Stormwater P3 Project for the City as the Prime Consultant and Construction Manager at Risk (CMAR). The Green Stormwater Infrastructure (GSI) project, consisting of integrated Best Management Practices were evaluated and installed in four distinct neighborhood areas and business corridors. In addition, technical evaluations and feasibility studies were conducted to identify projects in nearby areas in order to secure funding and implement regional solutions under the Safe, Clean Water Program. The objectives of this effort are to improve water quality, increase groundwater recharge, reduce nuisance flooding, and maximize value and use of funds. The project will capture and infiltrate approximately 354 acre-feet per year (AFY) while reducing implementation risk to the City and increasing the local economic and community impact benefits, in an effort the increase a sustainable triple-bottom-line. Substantial completion will be followed by a one-year monitoring and optimization period, with the option to extend an additional two years.

The implementation of green stormwater infrastructure included the utilization of small, emerging, women-owned, minority-owned, and disabled veteran-owned businesses to promote opportunities for these groups, meeting City utilization goals. Key to this effort was a partnership with Corvias Solutions in the development of a capacity-building, business incubation program that will provide necessary skills and experiences to local small businesses to deliver GSl projects.
