The 2017 update to the Central Valley Flood Protection Plan, to be released later this summer, radically revises the flood control strategies that have prevailed for more than a century. The plan recognizes the connections between the flood system, the water system and the ecosystem, and relies less on levees and more on floodplain restoration to upgrade the state’s aging and inadequate flood control infrastructure.Read More
If you peek through the chain link fence behind the Ross Post Office in Marin County, you will see a suburban creek that looks much like any other. Some sections of bank are armored with riprap and wire, others with concrete, and others not at all. Scattered alders grow at the edge of water that riffles over stone and around muddy bends.

When Bay Area voters approved Measure AA in June 2016 they not only created a significant new source of environmental funding, they also made California history, levying a parcel tax across the entire region for the first time. The measure, which resulted in creation of the SF Bay Restoration Authority, may be a catalyst for a regional approach to wetland restoration, rising sea levels and other challenges.Read More
Anyone who’s been around debates about the Delta’s highest and best uses for decades has seen a long train of plans touting this or that kind of restoration to save salmon, smelt, mice, birds and other endangereds. What’s different about the San Francisco Estuary Institute’s recently released Delta Renewed guide is that it finally puts all that’s been learned together in one place in a mere 100 pages.Read More
Off a bustling Delta highway, next door to a branch of the California Aqueduct, sprawls a tidy collection of shipping containers, humming pumps, and cylindrical tanks. This resolutely artificial site is devoted to preserving a disappearing piece of natural California: the Delta smelt. “Our fish are a refuge population,” says Tien-Chieh Hung...Read More
Environmentalists are heading warily into the fall following two regulatory developments that they fear may cramp efforts to protect California’s wetlands. In June the State Water Resources Control Board released a draft document overhauling wetlands protection procedures but leaving open the question of exactly which wetlands are eligible for protection. In the same month the U.S. Supreme Court ruled that landowners may mount court challenges to U.S. EPA or Corps of Engineers jurisdictional determinations before a permit is issued, potentially generating a torrent of wetlands-related litigation.Read More
There’s a big dispute over a small island at the edge of the Suisun Marsh. John Sweeney, the current owner of Point Buckler Island via a limited liability corporation, faces enforcement action by the Bay Conservation and Development Commission and the San Francisco Bay Regional Water Quality Control Board for diking and draining a tidal wetland and dumping excavation spoils in Suisun Bay. The extensive work he did was subject to regulation by state and federal agencies, and no authorization for it was ever requested or granted.Read More
Whatever the “perturbation” coming our way – a flood, a drought, a weed or Donald Trump – our recovery, in the aftermath, depends on something ecologists call resilience. It’s a term everyone is pasting onto their management initiatives these days. But what exactly does it mean?Read More
Surprising many observers, Governor Jerry Brown announced late in April that the Bay Delta Conservation Program, which had embraced the new water conveyance popularly known as the Twin Tunnels and a broad program for restoring the complex and heavily impacted Delta environment, was being split into two new entities: Cal WaterFix and Cal EcoRestore. On the restoration side, he announced a more modest goal of 30,000 acres, down from the original 100,000.Read More
Real estate developers often name their projects for what they’ve displaced: Quail Acres, Live Oak Estates. Egret Bay would have been another such necronym. The 4,500-home development proposed for the former Cullinan Ranch on San Pablo Bay in 1983 would have left little room for egrets, or other birds. A citizen’s group, Vallejoans for Cost Efficient Growth, supported by Save the Bay and other environmental organizations, helped kill Egret Bay, and, in a deal brokered by Congresswoman Barbara Boxer, the land became part of the San Pablo Bay National Wildlife Refuge. Then came the process of restoring the badly subsided 1,500 acres to tidal wetland. On January 6, the dike between Cullinan and Dutchman Slough, a tidal arm of the...Read More
The numbers are daunting: 8,000 acres to be restored to fish-friendly tidal habitat in order to comply with federal wildlife agencies’ Biological Opinions; another 65,000 if and when the Bay-Delta Conservation Plan is implemented; more still if you add in mitigation for levee operations. Where will that acreage come from? State agencies and other public entities already own some parcels suitable for restoration, but not nearly enough: the rest will need to be purchased from its current owners or covered by easements. (Eminent domain is not on the table; it’s not even clear if it could be invoked for habitat purposes.) And legal constraints make buying land in the Delta harder than you might think. Dennis McEwan of the Department...Read More
Along Alameda Creek, which drains a 640-square-mile watershed, humans have built dams, buried creeks, and reshaped channels. “The watershed is huge and complex, and all these changes, compounded over time, have left us with a long and arduous path to getting it to function more naturally again,” says Carol Mahoney, a planner for Zone 7 Water Agency.Read More
An issue paper endorsed by the Delta Stewardship Council this August seeks to spark progress throughout the myriad stages of habitat restoration. As public and private interests gear up to help endangered fish and migrating birds by restoring habitats in six priority zones of the Delta and Suisun Marsh, this paper lays out tools and concepts for getting the most out of these investments and learning from our mistakes. The paper details steps for achieving effective restoration, reviews barriers such as conflicts with existing land uses and the complexity of permitting processes, and recommends strategies for addressing these challenges.Read More
Remember that chart showing how a bill becomes a law in your high school civics textbook—all those boxes and arrows? Odds are it didn’t include the Suspense File of the Assembly Appropriations Committee, a legislative limbo where bills can expire without ever coming to a vote. That was the fate of Senate Bill 1199, a measure introduced by State Senator Loni Hancock (DBerkeley) in April to add portions of the Mokelumne River to the California Wild and Scenic Rivers System. Supported by Friends of the River, the Foothill Conservancy, and the Calaveras County Board of Supervisors, SB 1199 cleared the Senate in May. In the Assembly, Appropriations Chair Mike Gatto referred the bill to the Suspense File because of its alleged fiscal...Read More
Breaching the outboard levee near Marin County’s Hamilton community this May is cause for both a whoop of celebration and a sigh of relief. Celebration because it was an ambitious wetland restoration project with a complicated design and multiple partners that wasn’t easy to pull off, yet in just a few months it’s become a beautiful landscape filled with blue water, green shoots, yellow flowers, quacking ducks, and happy neighbors. Relief because at times the costs and challenges of moving so much mud to the site, in order to the raise the elevation of subsided wetlands, seemed overwhelming to those in charge. But they did it. And now they need to do it again; only this time they hope it...Read More
Restoration planners were worried that connecting a former salt evaporation pond with the Bay could introduce long-dormant mercury to the wider ecosystem, and initial studies of levels in water bird eggs and fish reinforced that concern. A set of adjustable gates between the pond and the river allows seasonal closure of the pond and the ability to control the flow. But that raised a new question: would the river’s steelhead run get sidetracked...Read More
For years, Skaggs Island was a tantalizing blank in the map of San Pablo Bay wetlands restoration. Renee Spenst of Ducks Unlimited says it was “one of those places in a strange limbo.” Two-thirds of it was owned by the US Navy; the rest was privately-owned farmland. Converting any of the 4,400 acres back to tidal wetland was out of the question. “The agencies doing restoration just had to work around these two parcels,” recalls Beth Huning...Read More
Walk back through time with this sampling of early stories from Estuary's first two decades of publication. Many stories of the day focused on rescuing creeks and rivers from culverts and rip rap, restoring diked or farmed wetlands, and experimenting with techniques to bring native species back to altered landscapes.Read More
Nothing could be stranger than sitting in the dark with thousands of suits and heels, watching a parade of promises to decarbonize from companies and countries large and small, reeling from the beauties of big screen rainforests and indigenous necklaces, and getting all choked up.
It was day two of the September 2018 Global Climate Action Summit in San Francisco when I felt it.
At first I wondered if I was simply starstruck. Most of us labor away trying to fix one small corner of the planet or another without seeing the likes of Harrison Ford, Al Gore, Michael Bloomberg, Van Jones, Jerry Brown – or the ministers or mayors of dozens of cities and countries – in person, on stage and at times angry enough to spit. And between these luminaries a steady stream of CEOs, corporate sustainability officers, and pension fund managers promising percentages of renewables and profits in their portfolios dedicated to the climate cause by 2020-2050.
I tried to give every speaker my full attention: the young man of Vuntut Gwichin heritage from the edge of the Yukon’s Arctic National Wildlife Refuge who pleaded with us not to enter his sacred lands with our drills and dependencies; all the women – swathed in bright patterns and head-scarfs – who kept punching their hearts. “My uncle in Uganda would take 129 years to emit the same amount of carbon as an American would in one year,” said Oxfam’s Winnie Byanyima.
“Our janitors are shutting off the lights you leave on,” said Aida Cardenas, speaking about the frontline workers she trains, mostly immigrants, who are excited to be part of climate change solutions in their new country.
The men on the stage, strutting about in feathers and pinstripes, spoke of hopes and dreams, money and power. “The notion that you can either do good or do well is a myth we have to collectively bust,” said New Jersey Governor Phil Murphy whose state is investing heavily in offshore wind farms.
“Climate change isn’t just about risks, it’s about opportunities,” said Blackrock sustainable investment manager Brian Deese.
But it wasn’t all these fine speeches that started the butterflies. Halfway through the second day of testimonials, it was a slight white-haired woman wrapped in an azure pashmina that pricked my tears. One minute she was on the silver screen with Alec Baldwin and the next she taking a seat on stage. She talked about trees. How trees can solve 30% of our carbon reduction problem. How we have to stop whacking them back in the Amazon and start planting them everywhere else. I couldn’t help thinking of Dr. Seuss and his truffala trees. Jane Goodall, over 80, is as fierce as my Lorax. Or my daughter’s Avatar.
Analyzing my take home feeling from the event I realized it wasn’t the usual fear – killer storms, tidal waves, no food for my kids to eat on a half-baked planet – nor a newfound sense of hope – I’ve always thought nature will get along just fine without us. What I felt was relief. People were actually doing something. Doing a lot. And there was so much more we could do.
As we all pumped fists in the dark, as the presentations went on and on and on because so many people and businesses and countries wanted to STEP UP, I realized how swayed I had let myself be by the doomsday news mill.
“We must be like the river, “ said a boy from Bangladesh named Risalat Khan, who had noticed our Sierra watersheds from the plane. “We must cut through the mountain of obstacles. Let’s be the river!”
Or as Harrison Ford less poetically put it: “Let’s turn off our phones and roll up our sleeves and kick this monster’s ass.”
4th California Climate Change Assessment Blues
by Isaac Pearlman
Since California’s last state-led climate change assessment in 2012, the Golden State has experienced a litany of natural disasters. This includes four years of severe drought from 2012 to 2016, an almost non-existent Sierra Nevada snowpack in 2014-2015 costing $2.1 billion in economic losses, widespread Bay Area flooding from winter 2017 storms, and extremely large and damaging wildfires culminating with this year’s Mendocino Complex fire achieving the dubious distinction of the largest in state history. California’s most recent climate assessment, released August 27th, predicts that for the state and the Bay Area, we can expect even more in the future.
The California state government first began assessing climate impacts formally in 2006, due to an executive order by Governor Schwarzenegger. California’s latest iteration and its fourth overall, includes a dizzying array of 44 technical reports; three topical studies on climate justice, tribal and indigenous communities, and the coast and ocean; as well as nine region-specific analyses.
The results are alarming for our state’s future: an estimated four to five feet of sea level rise and loss of one to two-thirds of Southern California beaches by 2100, a 50 percent increase in wildfires over 25,000 acres, stronger and longer heat waves, and infrastructure like airports, wastewater treatment plants, rail and roadways increasingly likely to suffer flooding.
For the first time, California’s latest assessment dives into climate consequences on a regional level. Academics representing nine California regions spearheaded research and summarized the best available science on the variable heat, rain, flooding and extreme event consequences for their areas. For example, the highest local rate of sea level rise in the state is at the rapidly subsiding Humboldt Bay. In San Diego county, the most biodiverse in all of California, preserving its many fragile and endangered species is an urgent priority. Francesca Hopkins from UC Riverside found that the highest rate of childhood asthma in the state isn’t an urban smog-filled city but in the Imperial Valley, where toxic dust from Salton Sea disaster chokes communities – and will only become worse as higher temperatures and less water due to climate change dry and brittle the area.
According to the Bay Area Regional Report, since 1950 the Bay Area has already increased in temperature by 1.7 degrees Fahrenheit and local sea level is eight inches higher than it was one hundred years ago. Future climate will render the Bay Area less suitable for our evergreen redwood and fir forests, and more favorable for tolerant chaparral shrub land. The region’s seven million people and $750 billion economy (almost one-third of California’s total) is predicted to be increasingly beset by more “boom and bust” irregular wet and very dry years, punctuated by increasingly intense and damaging storms.
Unsurprisingly, according to the report the Bay Area’s intensifying housing and equity problems have a multiplier affect with climate change. As Bay Area housing spreads further north, south, and inland the result is higher transportation and energy needs for those with the fewest resources available to afford them; and acute disparity in climate vulnerability across Bay Area communities and populations.
“All Californians will likely endure more illness and be at greater risk of early death because of climate change,” bluntly states the statewide summary brochure for California’s climate assessment. “[However] vulnerable populations that already experience the greatest adverse health impacts will be disproportionately affected.”
“We’re much better at being reactive to a disaster than planning ahead,” said UC Berkeley professor and contributing author David Ackerly at a California Adaptation Forum panel in Sacramento on August 27th. “And it is vulnerable communities that suffer from those disasters. How much human suffering has to happen before it triggers the next round of activity?”
The assessment’s data is publicly available online at “Cal-adapt,” where Californians can explore projected impacts for their neighborhoods, towns, and regions.
