Hahamongna Is a Spectacular Environmental Treasure . . .
But It's Not Going to Be When the County's Trucks Start Rolling

  • Imagine 425 loud, double-bedded diesel trucks ripping through Hahamongna Watershed Park and your neighborhood every weekday for five years!
  • scrapping out 2.4 million cubic yards of dirt and sand
  • belching diesel fumes and spewing dust all the way
  • closing favorite trails and passages
  • congesting local streets and freeways
  • permanently destroying more than 50 acres of precious stream habitat
  • and the noise will be horrendous!

That's the LA County Flood Control District plan, and it will begin soon, if you don't do anything about it. County officials didn't listen to the wide-spread public support for a careful, ongoing program of stream restoration and sediment management in the fabulous Arroyo Seco.

The program, adopted by the County Supervisors in November, 2014 would mean 425 trucks per day will haul sediment from the park to distant landfills for move than five years, removing more than 2.4 million cubic yards of sand and sediment from the basin, scraping it to a level not seen since the 1930s. More than 150,000 diesel-belching trucks; traffic, noise, dust, pollution, habitat destruction, and a permanent 50 acre maintenance yard in the middle of a streamzone.

The Arroyo Seco Foundation and Pasadena Audubon say "No Big Dig!" We support the program adopted by the Pasadena City Council that would provide flood protection and preserve Hahamongna and our neigborhoods.

Hahamongna is the most special environmental treasure in our region. We can't let LA County Flood Control District destroy it and degrade our neighborhoods. The Arroyo Seco Foundation and the Pasadena Audubon Society have filed a lawsuit to protect Hahamongna and our neighborhoods. Our goal is to secure a more moderate and sustainable program that will reduce impacts on Hahamongna Watershed Park and on our neighborhoods.

Please give generously. The fate of Hahamongna and our neighborhoods depends on your generosity.

We are looking for 250 people who can give $100 each to protect Hahamongna for future generations.
