Report must spur us to look at actions we can take to reduce emissions and prepare our communities to adapt
The latest report from the Intergovernmental Panel on Climate Change (IPCC) from the world’s scientific community leaves no doubt that we must take urgent action on climate change while we still have a chance to prevent the most destructive impacts to the globe’s communities and ecosystems. This report must spur every one of us to look at actions we can take in our region to rapidly reduce emissions and prepare our communities to adapt.
More than issuing a wake-up call, this report offers concrete actions that we can take and emphasizes the valuable role of nature-based solutions that reduce climate change risks, while providing numerous benefits to both our communities and the planet.
One of the most effective nature-based solutions is the expansion and restoration of coastal wetlands. Wetlands not only provide valuable habitat for fish and birds, acting as the base of the marine ecosystem, but wetlands have also been shown to be one of nature’s most efficient plant communities for capturing carbon from the atmosphere, trapping organic carbon quicker and better than forests, thus reducing carbon in the atmosphere.
Coastal wetlands also help to buffer our communities from sea level rise, acting as a sponge to capture flood waters before they reach our homes and businesses. In short, wetlands, if protected, expanded and restored, are one of the most valuable ecosystem tools for reducing the impact of climate change.

The restoration of the Sonoma Creek in the San Francisco Bay Area not only corrects problems of the past, but also looks to the future.
The sun shines meekly through a veil of morning fog and wildfire smoke while several figures in orange vests, hard hats, and face masks move slowly through a marsh on the north shore of San Francisco Bay. Wielding brooms, they jab lightly at the vegetation, ruffling the tufts of native pickleweed. As biological monitors, their job is to flush out small animals—especially the endangered salt marsh harvest mouse—and usher them from the path of a rumbling excavator, which is about to dig a deep groove in the slick mud.
It’s early October at the mouth of Sonoma Creek, where an unusual conservation project that broke ground five years ago is nearing the finish line. Audubon California and partner agencies are turning what was once a 400-acre stagnant backwater into a thriving wetland ecosystem that will serve as a refuge from rising seas for decades to come.
This revitalization of Sonoma Creek marsh is more a story of creation than one of restoration. The place is a product of the Gold Rush era, when torrents of unearthed sediment choked the Sacramento River system and later settled downstream. While hawks, grebes, and plovers made use of the area, which is managed today as part of the San Pablo Bay National Wildlife Refuge, the marsh wasn’t exactly a haven. The unnatural mud buildup was too rapid, preventing the formation of the channel systems that typically run through wetlands like arteries and allow a healthy water exchange with adjacent bays and estuaries. “If this was a natural marsh, it would look like a lung—it would breathe,” says Andrea Jones, director of bird conservation at Audubon California.

The Sonoma County Board of Supervisors this week unanimously approved expansion plans for a Sonoma hunting and sport shooting club while also imposing development restrictions sought by opponents of the project.
The outcome supported a compromise deal reached earlier this year between principals of the Wing and Barrel Ranch and a representative for several Sonoma-area residents who objected to the project.
The agreement reduces the size of the proposed clubhouse by about a third, to 18,620 square feet, limits membership and usage numbers, and allows for more public access to the bird-hunting fields, a clay shooting course and a fly-fishing pond.
In addition to a new clubhouse, the county approval advance plans for a new shooting tower on the ranch, which sits on 975 acres of hayfields north of Highway 37, just east of the Highway 121 intersection.

State Route 37 — which snakes across Solano, Napa, Sonoma and Marin counties in Northern California — is living on borrowed time.
At times, the highway appears to be impassable because of the 44,000-plus vehicles that travel portions of it every day. However, the effects of climate change will render this critical northern Bay Area crossing absolutely impassable during high tides unless we collaborate regionally on the best way to balance traffic needs and the valuable wetlands the roadway straddles.
The societal challenge we face is adapting to environmental changes in a resilient way while being ecologically sustainable. In the Bay Area, rebuilding State Route 37 to avoid its potential loss in the next 20 years because of flooding will be our first regional foray into adapting to sea level rise — an issue that will threaten most of our shoreline infrastructure, coastal ecosystems and population centers.
State Route 37 provides a critical “northern crossing” of the San Pablo Bay as it stretches from Interstate 80 in the east, to Highway 101 in the west, serving local residents, commuters and visitors, as well as freight haulers traveling between the Central Valley and the Santa Rosa area. Today the highway is built atop a berm, an outdated method of building roads across marshes and waterways that constricts the ability of the bay to improve water quality by filtering out pollutants, produce more fish and wildlife, and absorb floods.
The temptation may be to work on a quick, easy fix that reduces traffic congestion while ignoring long-term consequences. These consequences include traffic congestion returning to current levels in a few years, and the San Pablo Bay tidal marshes being cut off from the life-giving ebb and flow of the tides.

North Bay motorists suffering through congested traffic on Highway 37 or long detours from closures of the roadway caused by flooding may wish for anything to relieve them of their misery.
But does that include paying tolls?
A fee-based future appears to be gaining traction with a key advisory group tasked with long-term solutions for traffic and flooding on the heavily traversed 21-mile highway from Vallejo to Novato.“
I think everyone acknowledges there’s few options other than tolls to generate revenue needed to do a project of that scale in that location,” said Sonoma County Supervisor David Rabbitt, chairman of the Highway 37 Policy Committee.
Rabbitt spoke Thursday following the committee’s meeting at Mare Island in Vallejo. The group includes representatives of transportation agencies in Sonoma, Marin, Napa and Solano counties, as well as the Metropolitan Transportation Agency.
Highway 37, which skirts the edge of San Pablo Bay, is increasingly at risk from sea level rise, and this winter was closed for weeks at a time as a result of storm-related flooding. The segment east of Sonoma Raceway, which narrows to two lanes, is a particularly problematic choke-point.

State highway officials are rushing to stabilize low-lying Highway 37 in northern Marin County on an emergency basis to prepare for another strong storm forecast to hit the region Thursday.
The highway has been inundated with flooding water from a series of January and February storms, causing road closures and traffic headaches for commuters dependent on the major Sonoma and Marin county thoroughfare.
A three-mile stretch of Highway 37 between Highway 101 and Atherton Avenue has been closed since Feb. 9. CHP officials Monday said they expected it to remain closed until at least Thursday while road crews work around the clock to raise it.
Caltrans has hired Santa Rosa-based Ghilotti Construction Co. to do the work, according to the CHP. A company representative couldn’t be reached Monday. A Caltrans spokesman didn’t respond to messages seeking comment.One of the lowest lying state roads in California, Highway 37 crosses marshlands, rivers and creeks along the San Pablo Bay.

“This is something we foresaw because there are several low spots along these berms and levees,” said [Fraser] Shilling, whose report, Rising Above the Tide, says sea levels have already risen 8 inches along the California coast.
Persistently swamped Highway 37 — historically a sore spot for motorists — is rapidly becoming one of the Bay Area’s most pressing issues as heavy storms keep rolling through this winter, forcing repeated closures of a crucial transportation link.
The peculiar highway, which looks more like a rural farm road in places, connects the North Bay to the East Bay by cutting through wetlands and hay fields along the northern shore of San Pablo Bay. Wine Country day-trippers use it, as do drivers headed to Sonoma Raceway and Six Flags Discovery Kingdom in Vallejo.
The increasingly popular artery, which was shut down for much of last week, has been closed for about three weeks this winter because of flooding.
The soggy blockages have raised aggravation levels among tens of thousands of commuters who use Highway 37 each day, and are providing a disturbing glimpse into what ecologists say is a wetter future, in which floodwaters powered by climate change could permanently drown the roadway.
“It is definitely the most problematic area in the Bay Area from the point of view of shoreline flooding and threats to communities and infrastructure,” said Fraser Shilling, co-director of the Road Ecology Center at UC Davis and author of a 2016 report analyzing the future of the highway.

Highway 37 was closed for nearly half of January. This 21-mile east-west corridor carries 44,000 vehicles each day and provides a critical link for commuters, weekend trips and freight hauling.
The recent news stories and editorial (“A glimpse of Highway 37’s flooded future?” Jan. 26) about flooding, correctly point out that local policymakers are working hard to figure out how to make the much-needed improvements happen quickly. It is not a simple nor easy task, but work is underway.
Two key facts have been established:Initial studies conducted by Caltrans and UC Davis provide preliminary analysis about how sea level rise will impact the corridor. It is dramatic information that shows complete inundation by the end of this century.
Traffic counts and analysis have been conducted to identify who is using the corridor at certain locations. The results show an even split among the four counties, but the direction of travel is very dependent on the time of day, with commuters going west in the morning and east in the evening.
There are five areas where action is underway:
1. Caltrans is pulling together plans and resources to raise the roadway where flooding occurred and pumping was needed.
2. The Metropolitan Transportation Commission has a contract already in place to analyze alternatives for all the problems facing the Highway 37 corridor — traffic congestion, flooding during storm events and other approaches such as bikeways, buses and rail. The $1 million evaluation of design alternatives will be completed in December.
3. Decisions on if and how a proposal to privatize a portion of the roadway — from Sears Point to Mare Island — fits into the solution.
4. Community outreach through public meetings, websites and social media have begun and will ramp up in 2017 as we have more detailed concepts related to environmental impacts, design ideas and funding options.
5. Funding is the most significant challenge. State and federal transportation money will be needed for a project of this size. Estimated costs far exceed $1 billion. And, at the same time, it is not the only large highway project we need to work on. In Sonoma County, we need to finish Highway 101; plus there are important projects on Interstate 80 at 680 in Solano County, on Highway 101 at 580 in Marin County and on Highway 29 in Napa County.
The funding challenge has led to an exploration of charging drivers like a toll bridge. In other corridors where this approach has been used — such as the Golden Gate Bridge — the user fees help provide the funds for improving and maintaining the corridor.
As the three Sonoma County representatives on the four-county policy committee, we ask for your help to find the best solutions.

Surveying flooding along Highway 37 in January, ecologist Fraser Shilling began doubting his projections for when climate change will cause severe, perhaps catastrophic impacts on the major North Bay thoroughfare.
In an influential 2016 report used as a guide for the highway’s future, Shilling, co-director of the Road Ecology Center at UC Davis, had established a timetable of several decades for those impacts to be fully realized.
But that was before January storms forced the full or partial closure of the highway for roughly 12 days, causing havoc for thousands of daily commuters.
“We’re starting to overwhelm the system in places that we were thinking we had 20 years of lead time. But we don’t,” Shilling said this week from his office in Davis. Delaying action could be catastrophic, he said, predicting that one day water will push over embankments and levees and the highway will be “gone.”
Highway 37, one of the lowest-lying in California, has long been threatened by climate change and rising sea levels, inadequate levees and political waffling over who bears responsibility for maintaining and upgrading the road. The 21-mile highway meanders across four counties — Solano, Napa, Sonoma and Marin — traversing tidal marshlands, rivers and creeks, and farmland where flooding presents a threat to livelihoods.
“You’ve got farms, freeways and frustrated drivers — and sea level rise,” said Brian Swedberg, who manages 525-acre Petaluma River Farms north of the highway across from Port Sonoma.

Editor’s Note: To the south, Sonoma and Napa counties melt into San Pablo Bay, a coastline of many marshy miles. When healthy, those wetlands function like natural sponges, filtering toxins and absorbing water from tidal surges and rising sea levels. Since 1996, the Sonoma Land Trust has been working to restore portions of that marshland, often breaching levees built by farmers to keep the water out. Here, historical ecologist Arthur Dawson explains the land’s history and its valuable environmental attributes.
The Sonoma Baylands have been nicknamed “big sky country,” and they are. Standing by the edge of the bay, there is a delicious sense of solitude. Millions of people live nearby, but you may not see a single one of them, even though the horizon stretches all the way to Mount Diablo and Tamalpais.
It wasn’t always this way. Fifteen thousand years ago you would have seen a wide valley, greened by countless creeks and dotted with the villages of the First Peoples. Across that valley flowed an enormous river, carrying half the runoff of California. A tremendous roar filled the Golden Gate, as all that water poured over a steep cascade on its way to the ocean, which lay beyond the hills that would become the Farallon Islands.
As the last ice age ended, the sea slowly rose and that valley was transformed into San Francisco Bay. Vast tidal marshes formed as pickleweed, tules and other salt-tolerant plants colonized the water’s advancing edge. This rich habitat attracted myriads of fish and birds. By necessity, the First Peoples periodically moved their villages to higher ground, but stayed close to the marsh because it was such a good place to hunt and fish.
With such abundant resources, the Bay Area was more densely populated than almost anywhere else in the Americas when the Spanish arrived in the 18th century. Groups along the marsh edge soon began losing their people to the missions. Some were taken forcibly, others chose to leave. Introduced diseases, against which they had no immunity, also took a heavy toll.
