Arroyo River Parks: Restoring a Living River

2021 presents an historic opportunity to restore and enhance the Arroyo Seco River. LA County is ready to move ahead with the long-delayed U.S. Army Corps of Engineers Arroyo Seco Ecosystem Study, and the LA Fish Passage Program has decisively documented the critical importance of the Arroyo Seco for steelhead trout and other aquatic species in the Los Angeles River. Attention is turning to the Arroyo Seco and its future.

The plight of Rainbow Trout in the upper watershed of the Arroyo and the CA Department of Fish & Wildlife's 2020 rescue program that translocated 469 trout into the Arroyo Seco just into the mountain canyon have generated a renewed focus on river restoration that is nature-based and enhances fish, wildlife and habitat for a resilient future. Several years ago the Arroyo Seco Foundation developed a guiding vision for this restoration — the Arroyo River Parks Program.

River Parks Vision

The goal of the Arroyo River Parks Program is to link existing parks and open spaces to each other and to the river. Rather than focusing on a few key sites along the 11-mile urbanized stream course, Arroyo River Parks is an approach that will integrate the more than 30 parks and open space linkages that line the concretized stream as part of a cohesive network supporting hydrological, ecological, and social connections — and emphasizing respect for place. Rather than just being parks that overlook a river, these parks and open spaces will be reconfigured as part of the river system.

We look forward to your involvement and support as we pursue this exciting opportunity for the restoration of the Arroyo Seco watershed.

Arroyo River Parks Principles

  • Integrate parks with the river and the river with the parks

  • Manage parks and open space to aid flood protection and water conservation and quality
  • Develop open space linkages for wildlife movement
  • Naturalize the stream and floodplain to restore riparian and aquatic habitat
  • Expand the trail network to connect parks, open spaces and cultural resources
  • Provide interpretative signage and educational programs to make the Arroyo an educational laboratory for Southern California
