Mayor Tornek Calls for New Arroyo Vision

In a luncheon speech to the Rotary Club, Pasadena Mayor Terry Tornek called for a "broad and deep discussion about the Arroyo" in the next year. "I believe we must develop a vision for the entire Arroyo and examine new models for governance and operations in the Arroyo," Tornek said.

ASF welcomes Mayor Tornek's call and looks forward to a renewed commitment to protecting and preserving our region's most important environmental treasure.

We Can Restore Native Fish in the Arroyo

Early pioneers of our region settled around the Arroyo Seco because of its abundant fish and water resources. The Arroyo was once a steelhead stream through which large trout migrated to the ocean and back again. But all that was wiped out by the flood mania.

The Arroyo Seco Foundation is pleased to announce that we have recently received a grant from the National Fish and Wildlife Foundation to assess conditions for fish and aquatic species in the Arroyo Seco and to take preliminary steps to restore native fish species including Rainbow Trout.

Autry Museum Exhibit and Native Plant Sale Will Feature Plants from Hahamongna Nursery October 7-9

The Autry Museum is undergoing a dramatic transformation. "California Continued," a series of exhibits and garden spaces will share how traditional ecological knowledge gained through centuries of experience can help present-day residents understand and care for the California environment. Beyond the galleries, a new ethnobotanical garden features more than 60 Native plants and activities that explore how generations of peoples, especially First Californians, have made use of plants and water. ASF is pleased to note that many of the plants have come from Hahamongna Native Plant Nursery, thanks to the good efforts of Nursery Manager Nicholas Hummingbird.

You will be able to buy plants from Hahamongna Coopertive Nursery at the Autry from October 7-9th.

Please Governor Brown: Do Something About County Flood's Black Carbon

"We're protecting people's lungs, their health by cutting out the poisonous chemicals that come out of diesel trucks, that come out of many sources - what is known as black carbon," Brown said during a news conference in Long Beach held with major supporters of the bill (SB 1383). "That's real stuff, and it goes from some machine into the air and into your lungs."

Imagine How Much Black Carbon the County's 425 Diesel Trucks A Day In And Out of Hahamongna Will Cause!

Supervisor Candidates State Their Position on the County's Big Dig Program for Hahamongna

Supervisor's Race Could Be Key to Hahamongna's Future

September 16, 2016 - The candidates to replace Supervisor Mike Antonovich addressed the County's Big Dig program for Hahamongna at a debate last night at Pasadena City College. The debate was sponsored by the League of Women Voters, Pasadena City College and the Pasadena Chamber of Commerce.

The candidates responded to a question from the audience that raised concerns about the enormous impacts of the Flood Control District's sediment removal program from the Devil's Gate Dam area in Hahamongna Watershed Park.

Kathryn Barger

Darrell Park

Candidate Kathryn Barger leaned on her experience as current Supervisor Mike Antonovich's Chief of Staff. She pointed out that after the Station Fire something needed to be done about the buildup of sediment in Devil's Gate reservoir. Supervisor Antonovich called for the County to do an Environmental Impact Report to assess the consequences. She backed the County's Big Dig program as "needed," but stated that she is willing to take another look at the issues to be responsive to community concerns.

Candidate Darrell Park decried the County's $70-$100 million trucking program to move dirt to a hole in Irwindale instead of to the beaches. He stated the County should use gravity to get the sediment down to the beaches where it needs to be. "The sediment didn't get by truck, and it's not going to get out of there by truck." He said that he is concerned about flood control, but the County's program Is "asinine". He would look into alternatives such as a sediment slurry to Southland beaches.
