Supervisors Scale Back Hahamongna Big Dig!

It's been a long campaign to reduce the negative impacts of the County Flood Control District's Big Dig in Hahamongna, but we scored a very significant victory on November 7 as the County Supervisor's voted to reduce the size of the sediment excavation program from 2.4 million cubic yards (mcy) to 1.7 mcy. Supervisor Kathryn Barger offered the key amendment that reduced the size of the plan and also included other important improvements to integrate the program with water conservation and stream restoration throughout the urban Arroyo Seco.

It's time to celebrate and to thank Supervisor Barger for listening to the voices of the community, but important issues still remain including:

  • The Flood Control District did not agree to reduce the number of truckloads per day from more than 400;

  • Nor will they reduce the impact area of precious riparian habitat that will be permanently desecrated;
  • The trucks will still spew deadly diesel pollution into our communities.

The Arroyo Seco Foundation and Pasadena Audubon and our attorneys are still on the job working to reduce these negative impacts of the Big Dig project. We are very grateful for your support.

Take the One Arroyo Survey!

Pasadena's One Arroyo, the advisory group formed by Mayor Tornek to shape a new vision for and commitment to the Arroyo, is sponsoring a survey to solicit public input about the future of the Arroyo.

With all the past neglect and competing uses in the Arroyo, it's important for the voices for a natural Arroyo to be heard. ASF's Arroyo River Parks approach and the US Army Corps Arroyo Seco Ecosystem Study are the visionary models, not cramming the Arroyo full of commercial facilities and new activities that don't belong there.
