Second Annual Hahamongna Walkabout Rocks

As we promised, the Second Annual Hahamongna Walkabout on Saturday, March 31 was fun, educational and inspirational! Walkabouters who braved the torrential drizzle were treated to some pretty awesome presentations. But Jason Carman of PCC captured the highlights on video, so everyone can share in the magic of the Walkabout.

EIR In Preparation
LA County Flood Control District is now considering what alternatives there are for their massive sediment removal and management program at Hahamongna. County staff expects to release a draft of their environmental impact report next Fall. We will keep you informed of developments, so check back here regularly or sign up for updates.
Emergency Measures Completed
County crews have now completed the emergency measures at Devil's Gate Dam. A mound of sediment and sand was moved from near the dam to the former Johnson Field on the west side of the Hahamongna basin. Some improvements were added to the dam and spillway to improve flood response.
These are the temporary measures approved by the County Supervisors in the Spring of 2011, while the Flood Control District prepares a more substantial sediment removal and management program.
The Significance of an EIR for Hahamongna
The Los Angeles County Supervisors on Tuesday, March 1, 2011 approved a motion instructing the County Department of Public Works to conduct a full environmental impact report on the sediment management program at Devil's Gate Dam and Hahamongna in the Arroyo Seco.
This victory is the first step in ensuring that Hahamongna and its nature as well as the local neighborhoods are protected. A very important step in the right direction! We are sure that everyone, including the County, will come out winners from a better program that includes the evaluation of impacts and alternatives and fully involves the cities and stakeholders.
Congratulations to all involved.
