Scoping Study of Los Angeles River-Arroyo Seco Confluence Park

Completed
By California Water Science Center December 4, 2018

The Mountains Recreation and Conservation Authority (MRCA) is considering plans for developing a new park at the confluence of the Los Angeles River and the Arroyo Seco. These plans include removing channel lining and creating a temporary lake using an inflatable rubber dam. Before implementing the plan, a wide array of scientific and engineering issues must be addressed. The U.S. Geological Survey (USGS) proposes to undertake a cooperative study with the MRCA to assess those issues that relate to the hydrologic, geochemical, seismic, and ecologic impacts of the confluence park development. 


The focus of this scoping study is to summarize and prioritize the relevant scientific issues related to the confluence project and delineate a set of work tasks required to adequately address these issues.

Geological, hydrological, and biological issues related to the proposed development of a park at the confluence of the Los Angeles River and the Arroyo Seco, Los Angeles County, California

A new park is being considered for the confluence of the Los Angeles River and the Arroyo Seco in Los Angeles County, California. Components of the park development may include creation of a temporary lake on the Los Angeles River, removal of channel lining along part of the Arroyo Seco, restoration of native plants, creation of walking paths, and building of facilities such as a boat...
