Good Policy, More Tests for Living Shores

While more sea walls may soon be necessary to adapt to rising seas, softer, greener, nature-based shorelines will also be important buffers for our cities and waterfronts. Wetlands, oyster reefs, eelgrass beds, and other natural features of shores and shallows figure largely in a number of ambitious, multi-partner restoration projects over the last decade. To date, more than 10 such projects have been or are being restored around the Bay, encompassing more than 200 acres of shoreline and nearshore areas. “We need larger living shoreline projects and we need them fast," said biologist Katharyn Boyer...

Speakers talk about emerging water quality issues such as stormwater management, contaminants in effluent, wastewater in Suisun Marsh, and nutrients discharged into the Bay.

Green Diet for Roads City of San Pablo project manager Amanda Booth went deep into the nitty gritty on green stormwater infrastructure at a State of the Estuary Conference session. “Talk to the utility agencies before you even start,” she said. “Read PG&E’s Greenbook guidelines. Know your city’s franchise agreements with gas, electrical, sewer, and water companies, figure out who pays to relocate facilities, for example, if that becomes necessary.” Changing the flow lines of runoff at the street, parcel and regional scale is what stormwater management via green infrastructure is all about. “Regional projects that treat regional drainage are the hardest to site,” said EOA Inc’s Chris Sommer during the session. “To build large stormwater retention projects at a...

Needed Now: A Big Blue-Green Push

From rain gardens to green streets to permeable parking lots and pebble dunes, landscape architects and resource managers are working to soften up shorelines and sidewalks, all to sponge up and filter stormwater runoff before it reaches the Estuary. This article details projects in the South Bay Salt Pond Project’s Eden Landing, Hayward’s Turner Court, and the Delta’s Elk Grove, and along the East Bay’s San Pablo Avenue and San Jose’s Chynoweth Avenue.

Super-Shore: A Multi-Habitat Experiment at Giant Marsh

Interview anyone of any stripe about the Giant Marsh living shorelines project and the same two words will be in every other sentence: high tide. Each construction step of this California Coastal Conservancy-led effort to build new native oyster reefs interspersed with eelgrass off the Contra Costa County shore must consider the timing of tides. High enough to float a barge or Boston whaler into the shallows, do a day’s work, and get back out again on the next cycle. Three feet at least of draft – the amount of boat below the surface which varies depending on its weight — and preferably not in the middle of the night. On April 18, as the contractor Triton Marine placed 180...

Clock Ticking for Cities to Commit to Greening

Managing stormwater is a physics problem, and not a very glamorous one. In decades past, the main objective of managing stormwater was figuring out how fast it could be directed through the Bay Area’s built landscape via storm drains, culverts, and channels, and into the Bay. In decades future, however, the object will be to slow down the runoff, and sink it into greener, spongier surfaces sprinkled throughout our cities and counties, or to run it through more meandering, more natural channels and drainages. Such measures fall under the classification of green stormwater infrastructure. And building more green infrastructure isn’t just some kind of concept or vision. Instead, the region’s water quality regulators want to see more of it from...

Therese McMillan inherits huge challenges as the new Executive Director of the Metropolitan Transportation Commission.

The Bay Area region is beleaguered by traffic, a crippling housing shortage, and growing inequality. MTC plays a role in all these areas. “We have a master coordinator role in being able to knit the region together through land use and transportation planning, and major dollar investments,” says McMillan of the MTC, which distributes billions of public transportation dollars collected annually by local, state and federal governments, although she notes that the agency doesn’t “have land use authority, or our own transit system—that is vested in the cities and counties, and separate transit agencies.” While land use and transportation are squarely within MTC’s purview, for others issues—housing affordability and growing economic inequities—MTC must partner with myriad other agencies across nine...

High Road or High Water for Wildlife

While we were cooped up inside waiting out February’s storms, many animals were on the move. Cameras positioned along a creek in the Pacheco Pass wildlife corridor captured footage of animals passing through a culvert under a bridge on SR-152 that crosses Pacheco Creek. “We caught a bobcat on camera walking through the creek,” says Tanya Diamond...

Green Cement Blues

For the last three years, an environmental storm has been brewing in the North Bay city of Vallejo. Some elements of the story are familiar: grassroots activists pitted against a multinational corporate developer, environmental justice versus the lure of new jobs. Add historical preservation, iconic wildlife, political shenanigans, and the unexpected involvement of the California Attorney General’s office, and the mix becomes more complex. An Irish cement company and its local partners want to build a processing plant and a marine terminal at the site of a long-closed flour mill on the east bank of the Napa River. Citing concerns over air quality and other impacts, the Vallejo Planning Commission rejected the applicants’ permit in 2017, a decision that the...

Calculating the Cost of Adaptation

What makes a bond green? When the debt is issued specifically to bankroll projects with tangible environmental benefits. So when the San Francisco Public Utilities Commission faced a hefty price tag for major infrastructure overhauls, they chose to go green. “The goal is to get to $1 trillion in annual green bond issuances by 2020,” says Mike Brown, the SFPUC environmental manager who oversees the $1.4 billion in green bonds that the commission has issued since 2015. To Brown, the global rise of green bonds presents an opportunity. “I want to get to the point where every dollar of debt issued is green.”

Medicating the Bay

“If you went to the doctor and told them you were taking 69 different pharmaceuticals,” says Emma Rosi of the Cary Institute of Ecosystem Studies, “they would be very concerned with your well-being.” When a study she co-authored detected that number of pharmaceutical compounds in caddisfly larvae along an Australian creek downstream of a treatment plant, it was further evidence that excreted drugs are escaping wastewater facilities and entering food webs. The Bay is no exception. A survey conducted by the San Francisco Estuary Institute found that seventeen commonly used drugs, including antibiotics, antidepressants, and over-the-counter painkillers, could exceed protective thresholds for marine life.

Recent Milestones for the Twin Tunnels and WaterFix

Spring and summer 2018 saw frenzied activity around California WaterFix, the latest iteration of a decades-long, on-again-of-again effort to convey fresh water from the Sacramento River to the South Delta while bypassing the Delta itself. Governor Jerry Brown has made WaterFix a top priority, but the project – including twin tunnels comprising the largest infrastructure project in state history – still faces a raft of uncertainties.

Nighttime lights on bridges shining into bays and rivers can attract and confuse fish as they migrate at night, leaving them vulnerable to predation.

“Well-lighted bridges and dams can create twilight conditions that predators love, especially other fish,” says Peter Moyle, professor emeritus at UC Davis. He recounts that at one point the Red Bluff Diversion Dam was lit up at night and pikeminnow took the opportunity to prey on juvenile salmon. “Opening up the gates helped because the pikeminnow were headed upstream to spawn so didn’t really want to be there, and the juvenile salmon could move past the dam quickly at night.” The Sundial Bridge in Redding is thought to have contributed to low numbers of fall-run Chinook salmon on the Sacramento River between 2011 and 2013. The Bay Institute’s Jonathan Rosenfield agrees that the problem from lights should be mitigated whenever...

North Bay: Common Ground on a Grand Bayway?

Traffic-choked, flood-prone Highway 37, traversing the northern Bay Area, has been locked for years in a debate between restoration groups and transportation agencies seeking what they thought might be opposing goals: resilient landscapes and a roadway meeting the North Bay’s transportation needs. As part of the Resilient by Design Challenge, the Common Ground team was assigned to bridge the divide over the highway’s future. “Getting committed to a long-term process is like driving cross-country in a car with different people,” says Tom Leader of Common Ground. “You’d be throwing away a lot of value by having a single-minded agenda.” Called the “Grand Bayway,” the team’s vision describes a raised road through an ecological Central Park, with revitalized ghost towns like...

San Leandro Bay: Three Cities Confront Common Estuary

There’s no easy way to describe what makes the San Leandro Bay region of the East Bay so unique. Ask a design specialist, like Claire Bonham-Carter of Resilient By Design’s All Bay Collective, and she’ll point to “massive infrastructure--the Oakland airport, the BART station, two major roadways…” On the other hand, community activist Colin Miller of the Oakland Climate Action Coalition says “It’s the people that really makes it special.” Miller and the other All Bay Collective community advocates pushed the team hard from the start to consider equity and social justice in all aspects of the project. The final result, a concept called “the Estuary Commons,” proposes to build tidal cities—pre-assembled housing units floating on excavated lagoons—but a huge...

NYC and Novato Sewage Plants Adapt

The city of Novato completed its $100 million new wastewater treatment plant in 2011. Raising the old plant was expensive, but helped protect it from sea level rise for at least this century. “We took a pretty conservative approach,” says general manager Sandeep Karkal, “but we think we’re in pretty good shape, even for a worst-case scenario.” Novato is far from alone in thinking about the impact of sea level rise on wastewater management. New York City recently discovered how complex the issue can be. After Hurricane Sandy, the Department of Environmental Protection, which oversees New York’s wastewater system, prepared a detailed report on vulnerabilities and adaptation strategies at all facilities. By spending $187 million across all 14 plants, the...

Though a tiny and low-lying treatment plant on the San Leandro shore is facing increasing regulation of nutrients and rising sea levels, it’s got a path to adaptation thanks to the region’s taxpayers.

This April, the San Francisco Bay Restoration Authority awarded the first round of Measure AA grants, including $539,000 for San Leandro’s water pollution control plant. The plant, which is surrounded by blue- and white-collar communities, recently completed upgrades that allow the repurposing of a retired treatment pond. The money will pay for plans, designs, and permit applications necessary to convert the pond to a wastewater treatment marsh and buffer zone between the plant and the advancing Bay—a critical improvement, since just 16 inches of sea level rise could flood 82% of the plant’s infrastructure . “We’re so little, without the right kind of help and a push from outside forces, it would be hard to initiate this kind of project,”...

Two Urban Estuaries Soften Shorelines

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 some practitioners as “soft shorelines” or “green shorelines,” living shorelines projects deploy a range of environmentally friendly alternatives to armoring shores against rising seas and stronger storm surges, along a gray-to-green continuum. As speakers described challenges encountered and progress made...

Overdue Levee Almost Shovel Ready

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 adjacent property owners and communicating with the local community. “It’s to the community’s benefit to get flood protection, but outreach cuts down on complaints,” says the Water District’s Rechelle Blank.

An easily overlooked slough is pointing a finger of uncertainty at Oakland’s plans for ballpark redevelopment, transit safety and resilient neighborhoods.

From the pedestrian bridge between the Oakland Coliseum and the BART station, the view of Damon Slough–a 25-foot-wide canal of muddy, litter-choked water–belies its increasing prominence in the flood-futures of east Oakland. A study by the Metropolitan Transportation Commission did the math, adding the impacts of rising sea levels on these Oakland flatlands to predictions of more frequent, more extreme storm events and urban runoff. “That’s when water starts coming out of manholes,” says Kris May, a coastal engineer who worked on the study. Redevelopment plans for the Coliseum area take some sea level rise into account, but not the water added by storms to aging drainage systems and swollen sloughs. For the area around the Coliseum, the extra effects...
