When 1674 Highland Oaks Drive was built in 1952, it epitomized the California dream. Arcadia was fast becoming the third-richest city in L.A. County, right behind San Marino and Beverly Hills. The Army Corps brought military efficiency to the flood-proofing of the San Gabriels, and in 1960, the northwestern corner of Santa Anita Wash was cleared for a debris basin. But it wasn't until 1969 that Flood Control began clearing out the sediment choking the reservoir upstream. In 1971, local residents first fully realized what would replace the Baldwin-era "noble trees" behind their homes. Three piles of dam debris were planned, each of them eventually reaching perhaps 70 feet in height, with slopes etched by the tracks of dump trucks.

When the Arcadia Beautiful Commission complained about "eye pollution," Flood Control engineers replied that they were trying to save lives: 350 square miles of the San Gabriel Mountains had burned since development had crept up the skirt of their foothills. Rain on fire-scarred mountains caused mudslides. Did the residents of Highland Oaks Drive really want to weather the next rainy season downstream from a clogged dam?

The dam cleanout dragged on for two full years, while workers bulldozed the oaks at the north and south end of the Santa Anita Wash. Locals who worried about what would replace the once oak-ruffled canyon behind their homes were told that the sediment mounds would one day be landscaped to create a "park-like recreation spot."

Roughly 26 acres of the old woods remained when 12-year-old Camron Stone's family moved to the Arcadia Highlands in 1972. Yet to the boy's eyes, Flood Control's nearly 200-acre gated compound was already a park -- the best kind of park! -- the kind with no park keepers. After scrambling over county fencing, young Stone could skateboard down the debris basin spillway until bats began criss-crossing the sky at dusk. Conscious appreciation for the way the trees cooled the air and absorbed foothill smog, for the wild things that rustled in their deep bed of leaf litter, came only later, when he was a grownup, taking his mother on strolls through the woods on a road cut by Flood Control trucks. "She used to hike, but she can't go up in the mountains anymore," he said. "She could walk through the woods on the road, eyes up, not looking down."

Stone left Arcadia only long enough to get an engineering degree at UC San Diego. Now the father of teenagers, he still lives in the house that his parents bought. His first inkling that the days of his favorite strolling ground were numbered came in 2009, in what amounted to a pardon-our-dust flier from the Los Angeles County Department of Public Works, the agency overseeing Flood Control. At the meeting describing the procedure for yet another dam cleanout, Stone discovered that the roughly 40 residents present didn't seem to mind that Flood Control was planning to clear-cut half of the remaining woodland. "I got up and said, ‘Do any of you realize what they are going to destroy? There is a beautiful, pristine woodland over there that really should be a park.' I was basically shouted down," he said. "It was literally, ‘Sit down and shut up.' "

Stone is a big, blocky man, ruddy-cheeked and curly-haired. Scottish blood runs through his veins, and he has a red-haired daughter to prove it. When his neighbors wrote off his beloved woods, he got mad and stayed mad. Stone admits that, two years earlier, he missed the meeting held by Flood Control to canvas local opinion. "It was announced in a free weekly that they give away at the car wash!" he snorted.

The discretion of the announcement may have been deliberate. If there is one consistent theme regarding land management from Lucky Baldwin's day to Camron Stone's, it's a tradition of contempt for outsiders. In 1883, when a claim-jumper diverted some of Baldwin's water in Santa Anita Canyon, Baldwin allegedly paid to have him shot. But the Los Angeles County Flood Control District enjoyed no such remedy. Earth Day-era legislation required county engineers to produce environmental impact reports for things like cutting old-growth woodland. Inside engineering circles, this process is called "compliance." Sit through enough compliance-mandated public meetings, read enough environmental impact reports, and you, too, can find yourself wishing that Flood Control could shoot you.

Compliance for the felling of the Arcadia oaks took from 2007 to 2009. Four possible options were offered for the disposal of the half-million cubic yards of sediment behind Santa Anita Dam: the preferred alternative, which was felling the trees for the dump; doing nothing at all; then two options involving trucking the sediment to some suitable location, perhaps the gaping mining pits of Irwindale, about 10 miles east on the 210 Freeway.

Although Stone missed the compliance meetings, his neighbor two doors down, an officer with the Highland Homeowners Association, did not. Ralph Bicker declined to be interviewed for this story, but minutes from one of the meetings show that he was adamant from the outset that Flood Control fell the trees. By Bicker's calculation, trucking the sediment out of Santa Anita Wash instead of expanding the dump could mean as many as 400 trucks a day rumbling past the neighborhood's homes -- for as long as a year. Flood Control later amended that estimate to 160 trucks per eight-hour-day, 30 weeks a year, for two years.

Both the U.S. Fish and Wildlife Service and the California Department of Fish and Game recommended sparing the woods and trucking the sediment, but Flood Control rejected the advice as not meeting its needs. A Fish and Game spokesman shrugged off the insult, explaining, "We do not have any enforcement power."

Stone scrambled to save his childhood haunt. "I wrote letters to all the newspapers," he said. "Nothing." He pleaded with land conservancies to intervene. "Nothing." The December 2010 razing date was fast approaching when Stone snuck a reporter and photographer from the Pasadena Star News into the wash to see the condemned oaks. "They did a front-page story and -- boom! -- it went viral," Stone said. A petition was circulated. Local chapters of the Sierra Club, Audubon and the California Native Plant Society were loud in support. The Los Angeles Times began following the story.

On Dec. 7, 2010, the Los Angeles County Board of Supervisors, the five elected officials who oversee the enormous Los Angeles County Department of Public Works and its most powerful division -- Flood Control -- ordered a 30-day stay on the felling.

"Who are all these people?" demanded Ralph Bicker, nine days before Christmas 2010. Roused by Stone, roughly 100 turned up at Highland Oaks Elementary School to insist that the county supervisors make the moratorium permanent. A Flood Control spokesman reiterated the four alternatives originally suggested. But this time, Camron Stone offered a fifth one, reviewed by an independent engineer. Flood Control could still bring the sediment down-canyon on its conveyor belt, top off the existing dumps, cart out the remaining 125,000 cubic yards, and do it from an exit that would pass fewer homes.

It made sense, but it was too late. Incorporating a fifth option would have meant another new two-year round of compliance. From the time that the supervisors had ordered the moratorium in early December to the delivery of the new compliance report in early January, the rain gauge at the Santa Anita Dam had recorded 30.51 inches. Los Angeles was having the wettest December since 1889, when it flooded so badly that the Angeles and Santa Ana Rivers both changed channels, an entire winery was washed out to sea and the L.A. Times reported "sad havoc in fruitland."

In 2010, the Santa Anita Dam held, but every supervisor involved in the moratorium had been warned by Flood Control that the dam sat within a mile of the Sierra Madre fault, which is capable of producing earthquakes up to a magnitude of 7.5. In an earthquake, the sediment-choked dam might fail. An estimated 50,000 people lived in the path of the floodwaters. The woodland was condemned.

HCN you have done us all a great service publishing a very important story about the oak woodland and the sediment dump. I consider myself a member of the "environmental" community in southern California, and I am a avid HCN reader. It is good to see a piece focused, not only on southern California, but actually zeroed in on the belly of the beast... L.A. The cover story at that! Emily Green is a superb writer and her treatment of the history of land use, policy, real estate development, and population explosion, as they relate to our ecology, climate, weather, and mind-set was truly enlightening.

This story was all the buzz when the bull dozers were a-rollin', but no one gave it the perspective you did over a year later, with the narrative explaining how it is we got 10 million people to fit at the base of erosive mountains, and the after-story... where to go from here. How do we deal with a flawed old plan, based on our new values?

Yours is the first, and to my knowledge the only, big-picture piece on this. Once again HCN provides excellent journalism coming technically as an "out-of-town" outfit, (and by the way, there's no shortage on news outlets in L.A.), but right on the mark for evocative accuracy. Congratulations.

Of course we're talking about much more than a few acres of old oaks & sycamores. Ms. Green put real people, emotions, even motives into the story. Great symbolism as well... all you planners, advocates, thinkers, students of policy and environment, take heed of what's' going down in L.A. Stuff happens pretty fast out here.

I will definitely be pointing many people to this article, and for some of them it will be their first glimpse at HCN. Keep up the good work and thank you.

This is a great article by Southern California's best writer on the ongoing complicated disconnect between our unique natural ecology and our desire to control it. She doesn't just see the issue as dams versus trees, but weaves humans and their actions into an ecology that includes soils, flowers, leaves, roots, bats and birds and a history of the growth of our region. Think Chinatown written by E.O. Wilson. My takeaway is that activism is best served early before the decisions are made, and we can't assume anything around us is protected until we see it in writing.

Only western water journalist Emily Green could explain the sediment dumps of Los Angeles with flair & show readers so clearly & irrefutably the ecological and human impacts of our paved rivers, bulldozed lands, reliance on storm drains. She's right up there with John McPhee in her ability to uncrack the codes of compliance and engineering and show us what they have really wrought. Good for you, High Country News, for supporting this depth. Pls hire her to dig into Cadiz next.

By publishing such an indispensable, comprehensive account of an issue that has been all but forgotten by local news organizations, HCN has filled a critical role in keeping an accurate narrative of the sediment management issue in Los Angeles alive and well. As Emily Green has so eloquently explained, despite its hardened reputation, L.A. still has wild places worth fighting for. This overdeveloped, resource-hogging, behemoth of a metropolis has lessons to share and many to learn from its Western neighbors. Thank you HCN for including us in the conversation and thank you Emily Green for yet another compelling piece.

I'm really grateful to HCN and Emily Green for this thoughtful piece. This round of the sediment management plan won't provide a sustainable solution to the problem - but now is a good time to make the case for long-term solutions, and for that we're going to have to rethink the flood control system, or rather, remember it as a functioning riparian ecosystem - and find some managed middle ground that lets gravity do its emissions-less and free work of moving sediment downstream, and regain the attendant benefits of a natural or at least semi-natural stream (a nice place to hang out! aquifer recharge! fish! improved water quality!). There are channelized reaches of rivers and streams that maintain basic riparian functions already around (Glendale Narrows/LA River, San Jose Creek, Las Virgenes Creek to name a few) demonstrating that we can do it technically. Enough people are going to have to understand and see the relevance of this to LA's sustainability (the key: water resources) for it to gain traction politically.

To follow the inch-by-inch struggle to restore LA's waterways, please check out Jessica Hall's and Joshua Link's website LA Creek Freak.

http://lacreekfreak.wordpress.com/

Whereas I took a deep breath to do a big piece, Jessica and Josh have followed this issue blow by blow, in real time, for years. I recall from one of their posts the wonderful headline "It's sedimentary, my dear." Hall is such a basic source that she was the first person I called when considering taking on this story.

To appreciate the monumental challenge any environment writer or activist bloggers such as Hall and Link face in getting Los Angeles to consider restoring at least some flood plain function to the flood plain, it helps to know that due to the inversion layer and LA's famous smog, on most days, most Angelenos can't even see the mountains surrounding their basin. This even though the distance from Los Angeles Harbor to LA River headwaters in the Rio Hondo tributaries is only 40 miles. Fewer still of LA County's 10 million and counting are aware that LA even has rivers, albeit radically altered ones. The channels are rarely glimpsed from freeway overpasses and downtown bridges. Is the woodland/river/sediment cause a winnable battle? Ultimately, the mountains will prevail but at what cost and when are by no means clear. It does not look good. But the only uncynical act is to hope that LA County and 88 cities on the flood plain work with landscape ecologists such as Hall and Link to make LA's lost rivers an ecologically functional and beneficial amenity rather than hopeless menace whose backlog will turn the foothills and National Forest into an ever-increasing network of sediment dumps.

The Arroyo Seco Foundation, led by former Metropolitan Water District of Southern California Chairman Tim Brick, today issued comments on the draft strategic sediment management plan that

A) appears to have forced LA County to extend the comment period on the plan for another 90 days and

B) argues that "Sediment is not a waste product that should simply be disposed of, yet that is the approach taken by the Strategic Plan. Neither is storm water, another neglected resource. Six hundred thousand acre feet of storm water each year flow to the ocean from Los Angeles County, an invaluable resource that we need to better utilize. The management of the dams, debris basins and flood channels in Los Angeles County is critical to recovering some portion of that storm water."

When Tim Brick thunders, it should rain. He knows his H2O better than most engineers in LA County. MWD is the largest western water wholesaler outside of Reclamation. To read the entire statement, which also calls for a longer term, more holistic approach to sediment as part of overall watershed stewardship, follow this link
