The Arroyo Seco Foundation is a non-profit education and action organization.  Our goal is to preserve and enhance the Arroyo Seco watershed from the San Gabriel Mountains to the Los Angeles River, to promote sustainable management of the watershed and to foster environmental awareness and stewardship.


The Arroyo Seco Foundation has sponsored campaigns to restore and enhance the Arroyo Seco, Southern California’s most celebrated canyon.  Trees flourish throughout the Arroyo and native fish again swim in the stream as a direct result of ASF.  The Lower Arroyo Stream Restoration, developed in the 1990s, and the establishment of Hahamongna Watershed Park, and the restoration of the native fish, the Arroyo Chub, recently are the highlights of the effort.  This has all been accomplished with a massive infusion of volunteer labor and enthusiasm.

Direct beneficiaries per year:

Everyone who uses the Arroyo including its trail, the Rose Bowl, the aquatic center and its parks benefits.

Geographic areas served:

Los Angeles County


* Central Arroyo Stream Restoration Program * Arroyo Seco Watershed Coordination * Foothill Conservation Program * Save Hahamongna

For more than twenty years now, the Arroyo Seco Foundation has been championing the protection and enhancement of one of Southern California's environmental gems, the Arroyo Seco canyon and watershed. ASF had made the Arroyo an living laboratory and a model of watershed management. They restored the habitat and even re-introduced a native fish, the Arroyo Chub, to the stream.

I've personally experienced the results of this organization in...

the enthusiasm of young people who learn about nature and green jobs, the trees sprouting on the banks of the Arroyo, and the fish returning to the stream.

If I had to make changes to this organization, I would...

push even harder for substantial funding to restore the stream and watershed.

What I've enjoyed the most about my experience with this nonprofit is...

watching to area slowly be restored to more natural conditions.

The kinds of staff and volunteers that I met were...

friendly, smart and energetic.

If this organization had 10 million bucks, it could...

remove tons of concrete from the stream and restore native habitat and gish.

Ways to make it better...

we could move faster to upgrade teh Arroyo.

In my opinion, the biggest challenges facing this organization are...

institutional barriers to sound environmental management of the area.

One thing I'd also say is that...

ASF does exciting and rewarding that future generations will value.

When was your last experience with this nonprofit?
