Hahamongna is that rare spot in the Arroyo Seco at the foot of the San Gabriel Mountains where the mountainous watershed meets the urban plain. Periodically floods roar into this basin. Bounded on the north by the mountains and Jet Propulsion Laboratory and on the south by Devil's Gate Dam, Hahamongna contains five unique habitat zones that only exist in alluvial canyons near the mountains. Most sites like this in Southern California have been destroyed.
Don't let Hahamongna go the way of other lost environmental treasures in Southern California.
The original settlers of the region were sometimes called the Hahamongna Indians. The word means "Flowing Waters, Fruitful Valley" in the native Tongva language.
It's the most precious enviromental zone in our region, but it's under attack again.
Did we go to a different meeting of the Supervisors last November or what? We thought they reduced the size and impacts of the Flood Control District's Big Dig project by at least 30%, but that's not way the Flood Control District is acting. They now intend to build roads into basin in November and to destroy more than 70 acres of precious riparian habitat early next year.
We urge all who understand the value of Hahamongna and love it to sign the new petition now.
In November the County Supervisors reduced the amount of soil and habitat to be excavated and trucked out of Hahamongna by 30%. Then in December Judge Chalfant approved the impact report for the Big Dig. But there are still tremendous problems with the Flood Control District's devastating program. Like the 400+ diesel trucks and the massive permanent destruction zone.
ASF and Pasadena Audubon offered to settle our lawsuit with the Flood Control District if they minimize the impacts on Hahamongna and the local neighborhoods accordingly. Sadly the Flood Control District has responded negatively to our settlement offer.
We want all our supporters and friends to know that our attorneys have now appealed the original court decision as well as filed a second lawsuit to ensure that the Flood Control District reduces the negative impacts of their Big Dig.
We need your continuing support to win this historic fight to Save Hahamongna and preserve the Arroyo Seco as a wonderful natural resource for future generations.
November 8, 2017 — The LA County Board of Supervisors by a unanimous vote yesterday substanially modified and reduced the Flood Control District's Big Dig program for Hahamongna Watershed Park.
Besides reducing the size and negative impacts of the program, there were additional commitments made to support ecosystem restoration and water conservation in the Arroyo Seco. The vote represents a significant step forward toward Saving Hahamongna.
The County Flood Control District released their revisions to the Final Environmental Impact Report for their Big Dig mining and trucking operation in Hahamongna on July 24th. They have made some minor concessions, but the worst parts of their program are still there: 1) its too big; 2) too fast; and 3) too destructive to habitat, our air quality, traffic and neighborhoods.
There review period for public comments has now closed. Some excellent analysis of the defects of the EIR and its revision was submitted by agencies and concerned citizens. Now the Flood Control District has to review and respond to those comments and submit their program to the LA County Board of Supervisors for a new approval.
The ultimate decision on the fate of Hahamongna will be made by the County Board of Supervisors, which must act to certify that the entire EIR is in compliance with the California Environmental Quality Act (CEQA). This is the time for those who care about Hahamongna to speak with a loud voice telling the Supervisors to Save Hahamongna and ensure that the sediment removal program is reshaped along more sustainable and environmentally-sensitive lines.
150,000 double-bed, diesel belching monsters, clogging streets, creating noise, dust, pollution, destroying precious habitat and severely impacting our neighborhoods
Now that there's a new Board of Supervisors who are more progressive and environmentally oriented, it time for them to take a new look at the Flood Control District's devastating plan for Hahamongna and at the unchecked power of the Flood Control District.
