Public Learns of Corps' Arroyo Seco Restoration Program

November 16, 2016 - There was an air of excitement in the Pasadena Public Works conference room as the crowd gathered last night to learn about the U.S. Army Corps of Engineers program to restore the Arroyo Seco ecosystem. Charts and maps lined the walls presenting a somewhat overwhelming array of possilities, but the one hundred or more participants who came out for the workshop had the opportunity ask questions of the staff of the Army Corps and of the LA County Department of Public Works. Arroyo Seco Foundation representatives were also present to answer questions and address concerns.

The alternatives that were presented graphically included varied approaches to restoring eleven reaches of the Arroyo Seco from the San Gabriel Mountains down to the Los Angeles River. The basic proposals include full stream restoration, low-flow natural bottom stream channels, the removal of invasive species, and subsurface concrete box culverts to carry flood flow.

While a lot of questions went unanswered, most participants seemed positive and even enthusiastic about what they saw and told the Corps and the County as much.

Thanks to all who attended and participated. We suspect that you left the meeting with more questions than you came with, so we have prepared answers to some of the most important questions about the ecosystem restoration program.
