Hahamongna Cooperative Nursery Lives On!

March 10, 2016 -- Interm City Manager Steve Mermell has withdrawn the March 23rd eviction notice sent in January to the Arroyo Seco Foundation (ASF) for Hahamongna Cooperative Nursery and directed Pasadena staff to work out an agreement to allow ASF to continue to use the nursery facilities in Hahamongna Watershed Park. City Manager Mermell's action was in response to the vote of the Hahamongna Advisory Committee on February 25 to recommend an extension of ASF's use of the nursery facilities and overwhelming community support.

How Much of the Arroyo Seco Is Included in the Rim of the Valley Corridor?

We are glad the National Park Service has included some of the urban stretch of the Arroyo Seco in the new plan for the expansion of the Santa Monica Mountains National Recreation Area as the Rim of the Valley Corridor. We are now carefully reviewing the study and map because its seems that Arroyo Seco and foothill coverage has been reduced significantly from the draft report. Congressmember Adam Schiff is seeking public input on the final report before framing federal legislation to authoritize it.

Record Dry February; March Miracle Ahead?

February has brought back warm conditions and below average precipitation. Despite El Niños capacity to favor conditions for above average rainfall and snow, a high pressure system off the coast has stalled momentum for these conditions. The March 1st statewide snow survey: 83% of historical average.

BofA Employees Lend a Hand for the Arroyo Seco


An extraordinary team of 16 Bank of America employees gathered on February 27th to round up 439 pounds of invasive vegetation, trash, and debris from the Hahamongna Watershed Park. The project, coordinated by ASFs David Banuelas and Randy Caruso, was part of the Bank's "My Environment Chapter" of employees who volunteer for environmental causes. The team made an impact by removing Castor Bean plants that can serve as a breeding ground for the Polyphagous Shot Hole Bore so deadly to many native trees. Randy and his team found the event to be a great success and look forward to working with ASF in the future. If you would like to organize a corporate, club or school event, please contact David at
