The 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.
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.
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.
"To preserve and enhance the Arroyo Seco River and its watershed through education, community involvement, improvement projects, and advocacy."
