Pasadena Establishes Sediment Working Group





Siobhan Foster


Public Work Department Memorandum


DATE: February 6, 2014
TO: Michael J. Beck, City Manager
FROM: Siobhan Foster, Director of Public Works
RE: Devilís Gate Reservoir Sediment Removal & Management Project

With the January 21, 2014 closure of the comment period on the Draft Environmental Impact Report for the Devilís Gate Reservoir Sediment Removal & Management Project, the Department of Public Works is focused on scheduling the initial meeting of the Devilís Gate Reservoir Sediment Removal & Management Project Working Group.

The purpose of the ad hoc Working Group is to identify a responsible project design and sediment management program that reflects the configuration, aesthetics, habitat restoration, and vegetation management described in the Hahamongna Watershed Park Master Plan adopted by the Pasadena City Council in 2003. It is imperative that the project scope be appropriately scaled to provide adequate flood protection in the most environmentally responsible and respectful manner resulting in as little impact to Hahamongna Watershed Park and adjacent neighborhoods as possible.

The six member Working Group is comprised of individuals with the background and expertise necessary to lead this critical initiative, which will shape the future of Hahamongna Watershed Park and our community. Participants include:
* Don Bremner Sierra Club
* Tim Brick Arroyo Seco Foundation
* Gretchen Brickson Community Member
* Dr. Norman Brooks Irvine Professor of Environmental & Civil Engineering Emeritus, California Institute of Technology
* Nina Chomsky Friends of Hahamongna
* Dr. Seema Shah-Fairbank Assistant Professor & RBF Fellow, California State Polytechnic University, Pomona, Civil Engineering Department

Meeting dates and times will be established by the Working Group with staff support provided by the Pasadena Public Works Department. The intent is for the Working Group to conclude its work and provide input to City Manager Michael Beck in late-spring 2014.

This timing will allow the City to provide meaningful input to Los Angeles County prior to its anticipated publication of the final Environmental Impact Report in fall 2014.
