The Arroyo Seco Foundation

Charles LummisThe Arroyo Seco Foundation (ASF) was founded by Charles Lummis more than one hundred years ago to preserve and promote the Arroyo Seco, one of Southern California's greatest natural treasures. The Arroyo Seco is a spectacular stream and canyon that runs from high in the front range of the San Gabriel Mountains all the way to downtown Los Angeles.

After a lapse of many decades, the Arroyo Seco Foundation was revived in 1989 to continue that vision. Since then we have planted several thousand native trees in the Arroyo, participated in and led major Arroyo planning efforts, educated the public about the riches of the Arroyo, and most importantly worked to restore and enhance the natural splendor of the Arroyo for future generations.

ASF has brought over $25 million in funding into the Arroyo Seco Watershed. Some of the major projects have included the low-flow stream restoration program in the Lower Arroyo in the 1990s, the Central Arryo Stream Restoration Program, which brought back native fish to the Arroyo, the Watershed Coordination Program, and the Arroyo Seco Canyon Project.

ASF is a community-based 501(c)(3) nonprofit organization. We advocate an integrated, harmonious approach to watershed and flood management, water conservation, habitat enhancement, and the expansion of recreational opportunities. Through action projects, recreation, and environmental awareness activities, ASF strives to involve the residents and organizations in our region in this tremendous enterprise. As a member of the California ReLeaf tree-planting network, ASF works to reforest the Arroyo Seco, the San Gabriel Mountains and the neighboring urban landscape with native shrubs and trees.

The activities of the Arroyo Seco Foundation enable local residents and businesses to become directly involved in the restoration of the Arroyo Seco and in the recreational and environmental opportunities available.

Major Programs for 2017 include:
