Arroyo Seco Foundation and Pasadena Audubon Society File Lawsuit Against LA County Flood Control District

December 11, 2014 — The Arroyo Seco Foundation and Pasadena Audubon Society have filed a lawsuit challenging LA County Flood Control District's (LACFCD) project to scour the basin behind Devil's Gate Dam in Hahamongna Watershed Park in Pasadena.

The lawsuit will challenge the environmental impacts of the Flood Control District's Big Dig program, which would involve 150,000 diesel trucks removing more than 2.4 million cubic yards of sand and sediment from the basin behind Devil's Gate Dam over a five-year period and permanently degrading more than 50 acres of streamzone habitat there.

The massive nature of the excavation and sediment trucking program has raised serious community concerns over air pollution, traffic and public health. Both the Arroyo Seco Foundation and Pasadena Audubon Society have worked to develop and support alternatives that could provide adequate flood protection while protecting the habitat, wildlife, recreational opportunities and the neighborhoods surrounding Hahamongna Watershed Park in the Arroyo Seco, and the Pasadena City Council unanimously adopted similar recommendation. LACFCD, however, has refused to consider any alternatives other than a massive mining and trucking operation.

The Rain Finally Arrives... but we're not out of the drought yet.

Drought Monitory, October 7, 2014

With the recent storm and weather cooling off, some people think we are finally at the end of a long drought. One storm, however, doesn't break a drought. It will take years for our water supplies to recover, even with El Niño storms.

But as a recent New York Times article recently pointed out, our region is taking huge steps toward a more sustainable water future. Help us move closer to that goal!

  • Now is the best time to plant California native plants! Look for local varieties that are adapted to our climate.
  • How much water is running off of your property into the street? Rain barrels and rain gardens can help you capture some of that water, put it to use, and get it into the ground.
  • Don't forget that there are many rebates available for conservation investments around your home or business. Visit or contact your local water provider for more information.

Water restrictions remain in place, and some communities, such as Los Angeles, have increased the penalty for wasteful use. We urge you to take a few simple steps to help use water more efficiently. Los Angeles' Mayor Garcetti has issued a Executive Directive outlining an Emergency Drought Response for Los Angeles which includes some good action steps.

Visit our conservation page to learn more about how you can help.

Located along the Arroyo Seco, Highland Park was created in 1870 by developers who purchased the territory from Spanish and Mexican landowners. Incorporated into Los Angeles in 1895, it quickly became a thriving part of the city, and was once home to both Occidental College and USC's School of Fine Arts. At the beginning of the twentieth century, the Arroyo Seco was a center of the nation's emerging Arts and Crafts movement, and was home to one of Los Angeles' first great preservationists, naturalist Charles Fletcher Lummis.

San Gabriel Mountains National Monument designation has added new managers, funding to Angeles ForestDecember 10, 2014 — Officials speaking at a San Gabriel Valley Council of Governments meeting at the San Gabriel Hilton said the presidential visit and signing has awakened the U.S. Department of Agriculture, particularly the arm that manages the Angeles National Forest, the U.S. Forest Service, of the need for more resources in an area described as L.A.'s backyard.
Environmentalists to sue county over Devil's Gate Dam sedimentDecember 9, 2014 — Environmental groups are planning to file a lawsuit against Los Angeles County on Wednesday over its plans to remove sediment behind the Devil's Gate Dam in Pasadena.
Los Angeles, City of WaterDecember 6, 2014 — Recently Los Angeles has reduced its reliance on outside sources of water to become a leader in sustainable water management, a pioneer in big-city use of cost-effective, environmentally beneficial water conservation, collection and reuse technologies.
Wrong call on hauling Devil's Gate detritus: EditorialNovember 19, 2014 — We're loath to go along with most threats of legal action after an elected body has made its decision, right or wrong. In this case, the county's plan is so contrary to reason, so expensive, so ruinous to neighborhood tranquility for so many neighbors for a period of years, that we say: "See you in court!"
Depleting the WaterNovember 16, 2014 — It's been said that the wars of the 21st century may well be fought over water. The Earth's population has more than doubled over the last 50 years and the demand for fresh water - to drink and to grow food - has surged along with it. But sources of water like rainfall, rivers, streams, reservoirs, certainly haven't doubled. So where is all that extra water coming from? More and more, it's being pumped out of the ground.
