Hwy. 37 could be under water by 2050. Here’s how Caltrans plans to keep traffic flowing

Colin Atagi, NORTH BAY BUSINESS JOURNAL

The favored plan also proposes the route have a 60 mph speed limit, as well as two lanes in each direction with bicycle and pedestrian paths. The plan is in its early stages and officials haven’t identified a cost or funding source.

Caltrans, in order to keep traffic flowing decades from now, intends to build an elevated road along Highway 37 to combat rising water levels, which are expected to eventually inundate the North Bay arterial.

The proposed project essentially stretches across the existing route along San Pablo Bay and through Marin, Sonoma, Napa and Solano counties.

It preserves travel patterns, allows landward marsh migration and is resilient to sea level rises, officials said in explaining its benefits.

Wetlands advocates work to raise Highway 37

Dan Ashley & Tom Didion, ABC7 NEWS

There’s a vocal debate over building a better Bay Area, by building a better highway. At stake is not just traffic, but potentially vast stretches of restored wetlands.

When Kendall Webster gazes across the levees and farmland in southern Sonoma County, she can envision the tidal marshes that once flushed water back and forth from meandering waterways to San Pablo Bay.

“And so this whole flatland here was a mosaic of tidal wetlands,” she explains.

It’s a vast expanse of wetlands that the Sonoma Land Trust and their partners are working to restore.

“And you know, California is investing in climate, the way no other state in the country is right now. So we think that this is the natural infrastructure project that the state should be highlighting,” Webster maintains.

To make that vision a reality, the Trust has joined with Save the Bay and more than a dozen environmental and land management groups, urging Cal/Trans and the state to remove the one barrier that could open up natural marshland across the entire North Bay.

Rescuing FEMA (and ourselves)

Dan Farber, LEGAL PLANET

FEMA needs to grow in order to handle its work. The need for growth will only get greater as time goes on.

2021 was a year of disasters, with extraordinary heat waves, fires, a string of hurricanes, a cold snap that left Texas in the dark, winter tornados, and torrential rains. FEMA has been left badly overstretched. That’s an urgent problem, and it’s likely a foretaste of the future.

This is not just a problem for the overloaded folks at FEMA. It’s a problem for all of us, in an era where disasters are coming fast and furious.

The agency is stretched very thin indeed, with duties ranging from assisting with the care of detained migrant children, responding to COVID, supervising funding for rebuilding from past storms, and preparing for the upcoming season of wildfires and hurricanes. In May, according to the NY Times, “just 3,800 of the agency’s 13,700 emergency workers are available right now to respond to a new disaster,” about a third fewer than last year. The problem, the Times says, was not so much a lack of funding as a lack of staff.

Some of FEMA’s current assignments, like COVID response, are temporary. There’s every reason, however, to expect the pace of disaster situations to increase rather than slow. There are three reasons.

First and foremost, there’s climate change, which will result in an increase in the frequency and intensity of extreme weather events. The increase in frequency also means that there will be a greater number of disaster clusters, meaning that FEMA will be faced with multiple major disasters in short spans of time. The increased severity of disasters will also complicate and extend the post-disaster response, requiring corresponding commitments of staff by FEMA.

Sonoma Valley advocates push for reintroduction of beavers

Cole Hersey, NORTH BAY BOHEMIAN

On the southwest side of the City of Sonoma, a small stream named Fryer Creek cuts through a quiet neighborhood.

In late October, the creek was, like most waterways in the Bay Area, inundated with water during the “bomb cyclone” storm. However, as the rains pounded Sonoma with seven and a half inches of rain, Fryer Creek stayed fairly tame for the beginning of the storm, according to nearby residents Barabara and Larry Audiss.

“The water was really low [during the storm], even with the heavy rain, and then all at once the water was extremely high,” Larry Audiss said. “We went up and you could see where the dam had been breached.”

Larry Audiss is referring to a beaver dam close to MacArthur Street. The waters proved too strong for part of the recently built dam along this tributary of Sonoma Creek, likely pushing more water downstream.

This was not the only beaver dam in Sonoma Valley that was affected by the storm. In upper Sonoma Creek, most beaver dams were leveled by rushing waters.

However, the three beaver dams along Fryer Creek remained largely intact after the storm, perhaps due to the smaller size of the waterway. Even the dam that was breached could be rebuilt come next spring.

Rainstorm in review

SONOMA ECOLOGY CENTER

From bone-dry creek beds to rushing water in just one wet week – it’s been a turbulent ride of literal highs and lows for our watershed in the past seven days.

Last Sunday’s storm was the biggest in our area’s history in terms of volume of water over such a short amount of time. When you look at the numbers it makes quite the splash.

On the Sonoma Developmental Center campus where the Sonoma Ecology Center is located we received a total of 12 inches in 24 hours – when you factor in the 2.75 inches of rain that we measured prior to the Sunday, October 24 weather event we’re clocking in at 14.75 inches for this year. This is more than we received in precipitation all of last winter, all in just one week!

The huge fluctuations in streamflow which you can see represented below by a USGS streamflow graph of Sonoma Creek at the Agua Caliente Bridge aren’t a typical start to the wet season. In a couple of days Sonoma Creek went from running at 0 CFS (cubic feet per second) to well over 6,000 CFS. That’s a big change in a short amount of time.

Russian River, backed up at coastal mouth, threatens flooding in Jenner

Mary Callahan, THE PRESS DEMOCRAT

High waves and heavy surf that have battered the Sonoma Coast for days and sealed the Russian River mouth with a great mound of sand have raised the water high enough to threaten flooding in the town of Jenner over the next few days.

Water already surrounded the Jenner Visitor Center at the river’s edge by Thursday afternoon, rising over the back deck and flooding into the parking lot adjacent to the post office and Highway 1. Farther inland, the river’s surface swelled to a height of 10 feet at the Highway 1 bridge.

But because of continued wave action on the beach, it has not been safe for Sonoma Water, the county water agency, to send out a heavy equipment operator to breach the beach dam by digging a channel through from the river estuary to the ocean. And though there has been some recent rain, the river flow remains low enough that it’s not exerting sufficient pressure to break through the sand on its own.

That combination of factors has allowed the mouth to close a “crazy” number of times this winter, said Suki Waters, who grew up in the area and owns Water Treks EcoTours in town, running boat rentals and guided kayak tours in the estuary.

“There’s not enough pressure in the river, not enough current to keep the river open during these high waves, high sand-pushing events,” she said.

At various times, the waves have been high enough to wash over the sand berm, adding even more water to the estuary, Sonoma Water said.

This is the fifth time in two months that the mouth has closed, in large part due to a dearth of rainfall that this year is sitting at around 30% of normal in most of the North Bay and wider Bay Area, National Weather Service meteorologist Matt Mehle said. Santa Rosa, as of Thursday, had received 5.3 inches of rain since Oct. 1, compared to 15.5 inches in an average year, Mehle said.

The outlook is for dryer than normal weather through the end of the month, as well, Mehle said, and another high-surf advisory taking effect at 6 a.m. Friday, with waves up to 25 feet in the most exposed coastal areas.

Sonoma Water, the region’s drinking water supplier, and charged with managing conditions at the river mouth, normally would consider mechanical breaching of the sandbar once the water reaches between 7 and 9 feet high, said Barry Dugan, a community and government affairs specialist. It already has done so on three occasions over the past two months — Nov. 19, Dec. 10 and Dec. 30. One other time this winter, the mouth closed but the river breached on its own Dec. 24.

At more than 10 feet, the river “is pretty high,” said Waters, whose boats were moored near the visitor center, formerly the town’s boat house, and being monitored.

“Normally, it either breaks or, if the county can open the river mouth, it usually happens before it gets to 10 feet,” Waters said. “This is a rare event.”

The river usually runs at a rate of several thousand cubic feet per second at this point in the season, but even with the rainfall early this week, it flowed only at 459 cfs by 4 p.m. Thursday at the Hacienda Bridge in Forestville.

That’s at least high enough to allow sport fishing once again in the main stem, where between Oct. 1 and April 30 angling is shut down at 300 cfs under a 2015 regulation designed to reduce stress for imperiled fish species already challenged by drought.

Though the river rose to 300 cfs briefly Dec. 18 and again between Dec. 26-28, the river was not opened until Wednesday, when it peaked at 559 cfs before beginning to drop.

“Last year, it opened right before Thanksgiving. The year before that it opened in late October, closed, and then opened again in mid-November,” said Scott Heemstra, a longtime fishing guide and manager at King’s Sport & Tackle in Guerneville. “So this is pretty late for opening.”

With the river mouth closed, only smaller steelhead trout that came in early were available to be caught, however, and once the mouth is opened, the river flow could be too low to fish.

Whether the water in Jenner rises high enough in the meantime to mimic December 2015, when people were canoeing and kayaking through riverside parking lots, remains to be seen.

Dugan said the visitor center floods when the water reaches around 10.3 feet and the southbound lane of Highway 1 at 12.3 feet.

He said the CHP, Sonoma County Sheriff’s Office and public safety and park agencies had been notified of the situation.

But he said it remained difficult to predict what might happen.

“All I can say with any certainty is there continues to be the potential for localized flooding,” Dugan said.

Big atmospheric rivers are getting worse and do a lot of damage — especially in Northern California

Kurtis Alexander, THE SAN FRANCISCO CHRONICLE

During the first week of January 1995, a powerful storm lashed Northern California, pushing the Russian River over its banks for seven straight days and damaging more than 4,000 properties, what scientists now say is the costliest atmospheric river the West has seen.

A first-ever economic analysis of atmospheric rivers, released Wednesday as another series of these potent weather systems emerged over the Pacific, finds that such events have caused an average of $1.1 billion of flood damage annually over 40 years. The hardest-hit place, across 11 Western states with losses, was Sonoma County.

The 1995 atmospheric river alone resulted in $3.7 billion of damage, according to the study, from a storm that had mudslides covering roads, winds toppling trees and swollen creeks inundating homes. The event, which made landfall in Southern California and moved north, contributed to the total $5.2 billion of losses that Sonoma County has sustained from atmospheric rivers during the study period — 1978 through 2017.

The authors of the report, with the Scripps Institution of Oceanography at UC San Diego and the U.S. Army Corps of Engineers, warned that atmospheric rivers will intensify as oceans warm with climate change and that the losses will only grow. They called for more study of these systems so they can be better anticipated and their effects blunted.

A new UN report shows that we are not on track to avoid catastrophic climate change

Priya Shukla, FORBES

Yesterday, the United Nations released its Emissions Gap Report for 2019. It has been released each year since the Paris Accords were signed in 2015 and describes each country’s “emissions gap” by comparing the amount of greenhouses gasses actually being emitted to the volume of emissions necessary to avoid the impacts of climate change. This year, it revealed that global greenhouse gas emissions have continued to increase over the course of the past decade, despite the threat that climate change poses.

Because greenhouse gas emissions have steadily risen for so long, more severe cutbacks and changes will be needed in the future to prevent the planet from warming more than 1.5 to 2 degrees Celsius beyond pre-industrial levels. The United States has emitted the most greenhouse gases since 1750 and is failing to meet the reduction targets established in the Paris Accords, which it is currently in the process of withdrawing from. However, several other countries, including Canada, Japan, Brazil, and Australia, are also not on track to meet the commitments their countries made.
Today In: Innovation

The planet is already seeing more intense wildfires, storms, and heatwaves. And, in order to avoid further impacts of climate change, the report suggests that countries must decrease their emissions by up to five times more than what they already have. Specifically, they would have to decrease by 7.6 percent annually until 2030 to prevent the planet from warming above 1.5 degrees Celsius. This sort of dramatic reduction has only been seen during the fall of the Soviet Union when emissions fell by 6 percent in the United States and Japan.

Next month, the United Nations Climate Change Conference will take place to address how countries can work together to meet these emissions targets and next year they will meet to pledge even more cutbacks, as part of the Paris Accords. But whether they follow through on those commitments remains to be seen.

Polluted gravel pit breached in Russian River flood

Riverkeeper, RUSSIANRIVERKEEPER.ORG

Our worst fears were realized in the Feb 28th flood event. The largest gravel pit mine, Syar’s Basalt Pit, had a complete levee failure on a section that had failed in previous floods. The image at left shows the breach in center of picture, with river on the left and Syar Basalt Pit on right. Over 30 years of mining waste containing extremely high levels of toxic metals as well as Healdsburg’s treated wastewater discharges are now connected to our river – our drinking water supply.

Syar’s own testing in 2006 showed the mining waste contained mercury, iron and aluminum at 200-800% of safe levels and phosphorous at nearly 500 times higher than levels that can trigger toxic algae. Those pollutants are all conservative – meaning they are still present, do not degrade over time and pose a threat to the river’s health and our health.

When we filed lawsuits against the County in the 80’s and 90’s to stop the gravel mining, one of our biggest reasons was the fear of the gravel pits being captured by the river in floods. Sadly our predictions were correct, again. This occurred during the El Nino events in the late 90’s which resulted in a Clean Water Act lawsuit by Friends of the Russian River, RRK’s predecessor.

As of this date, three months after the flood, we’re still waiting for action plans to protect the river this summer from Healdsburg’s wastewater and the mining waste – both have very high levels of nutrients, mainly phosphorous, that could trigger toxic algae blooms. We’re also very concerned that in six months it’ll be raining again and if we do not take action we will see major erosion of downstream properties.

At this time, Permit Sonoma has convened two meetings with resource protection agencies and are developing a tentative plan. Permit Sonoma plans to hold a public meeting to collect comments on concerns regarding this issue and give you an opportunity to voice your opinion on how the County should respond to this major threat to the River’s health. We’ll keep you posted when the public meetings are scheduled, stay tuned!
