Save the Lower Arroyo Trees

We were dismayed to learn recently that Pasadena's Urban Forestry Advisory Committee by a 3-1 vote has recommended destroying four mature native trees that are part of the habitat restoration area in the Lower Arroyo. Their action was in response to a request by the Pasadena Casting Club to remove the trees so that they can expand their activities and hold tournaments at the casting pond there. Pasadena city staff opposed the Casting Club request in their staff report.

Destroying these stately trees would violate several Pasadena ordinances and plans, including the Arroyo Seco Public Lands Ordinance, the Tree Protection Ordinance and the Lower Arroyo Master Plan.

You can make a difference. Please sign the petition to save these trees and urge your friends and neighbors to do so as well

We Salute Mayor Garcetti and a United Community

Last Fall the Arroyo Seco Foundation and more than a dozen community organizations united together at the LA River Rally in support of Alternative 20, the most ambitious proposal of the US Army Corps of Engineers' ARBOR Plan to restore the Los Angeles River.

It didn't look very hopeful. The national office of the Corps seemed intent on going with a more modest proposal, but united community support and Mayor Garcetti's dynamic leadership turned the tide.

On May 28, 2014 the Corps announced that they will back Alt 20. It's a tremendous victory for the future of the Los Angeles River.

Pasadena Council Adopts Sediment Recommendations

On Monday, May 12, the Pasadena City Council adopted the recommendations of the Devil's Gate Sediment Working Group. This group was established by Pasadena to develop a more sustainable alternative to those presented in the LA County Flood Control District's Draft Environmental Impact Report on the Devil's Gate Sediment Removal and Management Project.

The Pasadena Sediment Plan would substantially reduce the scope and negative impacts of the Flood Control District's program, while protecting the neighborhoods and rare environmental values of Hahamongna Watershed Park and the Arroyo Seco.

Exceptional Drought Highlights Need for Water Conservation

Western U.S. Drought Map With "exceptional drought" declared in part of the state, the first ever zero allocation of water from the State Water Project, and numerous fires, we want to remind Southern Califorians that there are many ways that all of us can do our share to conserve water. It may be as small as fixing a leak or as large as installing a drought-tolerant garden.

Arroyo Seco Canyon Project

Arroyo Seco Canyon ProkectThe Final Conceptual Design Report for the Arroyo Seco Canyon Project is now available for public review! Thanks to all those who participated in the workshops and sent in comments. ASF, the City of Pasadena, and Carollo Engineers worked hard to incorporate public input as much as possible. The result, we hope, is a project that will not only integrate water resources, habitat, and recreation but will also satisfy the needs and desires of the community.

While there is no formal public comment period for this stage in the design, please feel free to direct any questions, comments, or concerns to Rebecca Shields Moose ( and Gary Takara (
