Looking east from the levee-top trail, a silvery swath of bay is dotted with low islands -- some tufted with plants, others mere muddy humps that barely break the surface. This is low tide at the nearly 1,000-acre Sears Point wetland restoration project on the western side of San Pablo Bay. The islands, 500 in all, are actually man-made mounds, scattered across the mudflat as an integral part of the restoration design. Each is roughly 60 feet across and was...Read More
Despite an official California policy in place since 1992 that calls for “no net loss” of wetlands, the lack of a specific wetlands definition has led to the loss of many thousands of acres of ecologically important lands. That could change soon, thanks to an update from the State Water Resources Control Board expected out soon after more than a decade of work. California environmentalists are optimistic that the updated policy, titled “State Wetland Definition and Procedures for Discharges of...Read More
Harbor Seals “have this dual existence,” says Sarah Allen, National Park Service ecologist. “They’re tied to the land physiologically and tied to the bay waters for food and travel.” From rocky islets to tidal marshes, the Bay shoreline offers respite to these native marine mammals. Rocky islets like the Castro Rocks, located near the Richmond-San Rafael Bridge, are particularly important refuges -- but more than half the islets that exist throughout the Bay are likely to be erased by sea-level...Read More
For three years, Kyle Hemes of UC Berkeley and colleagues kept tabs on the heat flux and air flow above three restored Delta wetlands on Twitchell and Sherman islands, and an alfalfa field on Twitchell Island. Surface temperatures at wetlands with open water were up to 5.1 degrees Celsius cooler than the crop field during the daytime. As expected, the dark open water absorbed more solar radiation, and released the energy slowly at night. But wetland vegetation played a role...Read More
“We are on track to complete the levees and transition zones next year so we can breach into the slough and restore the area to tidal action,” says Jim Levine, managing partner of Montezuma Wetlands LLC, which owns the property. The breach of the first major restoration area is planned for December 2019. This phase of the multi-phase project will restore 600 acres of previously subsided shoreline on the eastern edge of Suisun Bay to tidal, seasonal and some sub-tidal habitat....Read More
Development agreements were already in place for three parcels of land around Dutch Slough when John Cain first took a hike in this West Delta area in the spring of 1999. “It was clear as day to me that removing the levee would be a great way to restore freshwater wetlands at the mouth of Marsh Creek,” says Cain, who now works for American Rivers. Almost two decades later, earthmoving equipment is now preparing 1,178 acres for conversion to marsh...Read More
In Resilient by Design team Public Sediment’s effort to unlock Alameda Creek, the key lies in sediment--raw material needed to build levees and raise marshes so shorelines can withstand sea level rise. “We’re designing a suite of special structures, a mix of living and constructed features, to move more sediment and create a dynamic new equilibrium for the creek,” says team leader Gena Wirth. To get a conversation about sediment going, Wirth’s teammate Claire Napawan will often start by talking...Read More
East Palo Alto is a microcosm of Silicon Valley’s most pressing social and environmental issues. Home to low-income communities, the city faces rising rents and the displacement of longtime residents. As one of the lowest-lying communities in the Bay Area, it is also ground-zero for sea level rise in the South Bay. Although located at the northern end of Resilient by Design’s Field Operations Team’s 20-mile shoreline jurisdiction, much of their public engagement effort was focused on East Palo Alto....Read More
“Small sensors are the foundation of big science,” says Phil Trowbridge, director of the Bay’s Regional Monitoring Program which has just released a new synthesis report on sediment science. The report, combining the results of eight bodies of work, yielded some surprises concerning how much sediment moves from the Sierra and Bay watersheds to the Golden Gate. “The system is calming down after two huge disruptions,” says David Schoellhammer of the U.S. Geological Survey, referring to hydraulic gold mining and...Read More
This 8-minute film interviews eight directors of water quality, restoration, and environmental programs around the San Francisco Estuary about their experience of the 2017-2018 Resilient by Design Bay Area Challenge.Read More
For two cold clear days in February, scientists, engineers, and other specialists from all three North American coasts gathered at the Oakland Airport Hilton, in what a local speaker called “the least interesting part of Oakland,” for the second national Living Shorelines Technology Transfer Workshop. The event, co-sponsored by Restore America’s Estuaries, the California Coastal Conservancy, and Save the Bay, featured talks and interactive sessions on this emerging approach to coastal protection that went well beyond technology. Referred to by...Read More
After more than a decade of study and planning, the first part of a critical flood protection and environmental project is creeping towards construction near the town of Alviso. The South Bay Shoreline Project will eventually include over four miles of levee, 2,900 acres of restored tidal wetlands, and upgrades to the iconic Bay Trail. While the US Army Corps of Engineers waits on financing, other partners are focused on getting ducks in a row, such as coordinating access with...Read More
In January the Bay Conservation and Development Commission and the San Francisco Bay Regional Water Quality Control Board appealed decisions by a Solano County Superior Court Judge voiding $3.6 million in fines and cleanup and restoration requirements that the agencies imposed on the island’s owner for dumping excavation spoil in Suisun Bay and draining tidal wetland without authorization. The agencies held that due to the failure of previous owners to maintain levees, the interior of the island had become tidal...Read More
“The language changed from should restore to must restore,” says David Thomson of the San Francisco Bay Bird Observatory, referring to federal guidance on tidal marsh recovery. Marsh-upland transition zones are crucial for a properly functioning estuary, but nearly all of these historic zones have been impacted by human activity. Thomson, along with a number of partnering agencies have worked to figure out how to bring transition zones back to life. “We have seeded over 30 species of local native...Read More
“We’re finally seeing a change in paradigm,” says Brett Milligan regarding how sediment is treated in the Bay Area. What was once considered waste is now considered a resource, and a group called “Public Sediment,” part of the Bay Area Resilient by Design Challenge, are proposing mud rooms, mud berms, mud pathways, and top-to-bottom mud management to better build up Bay Area shorelines and keep them above rising water.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...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...Read More
If and when El Niño decides to dump a big storm on the Bay Area — even at 2:00 am on a Saturday night — SFEI’s Lester McKee and Alicia Gilbreath and their team are ready to pull on their parkas and dash out to take water samples. Last September, stakeholders in the Regional Monitoring Program decided they would be remiss if they did not try to measure some high priority pollutants during an El Niño year. “With plenty of...Read More
With its massive environmental and economic costs, it’s hard to see a bright side to the California drought. Consider mud, though. According to US Geological Survey scientist David Schoellhamer, the long dry spell may be giving tidal wetland restoration efforts an unexpected boost by promoting the buildup of sediment in the South Bay where former salt ponds await conversion to tidal marsh.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...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. Suess 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.
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.
