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

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.”...

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,”...

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...

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...

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...

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...

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...

All In for One Water

As climate change threatens to upend precipitation patterns and disrupt water supplies, agencies are increasingly searching for ways to wring more benefits out of every drop. The Santa Clara Valley Water District is seeking to take integrated water management planning to the next level through its One Water initiative. “The idea of One Water is to manage all water — treated water, groundwater, stormwater, flood water, water for habitat, species and Baylands — as one resource,” says the District’s Brian...

Worries Over Puny Pumps

Pump capacity, reliability, and cost are already big concerns for flood-control and sea level rise managers. “Gallon for gallon, it’s easily the most expensive way to deal with water,” says Roger Leventhal, a senior engineer with the Marin County Department of Public Works. “It’s not the ideal solution, but it’s the one we’re falling into.” New pumps, while costly in both dollars and electricity, are currently in the works. “It seems unlikely for us as a region to get away...

Indecision Point

The Delta Stewardship Council endorses the “Delta Plan Amendments for Conveyance, Storage Systems, and the Operation of Both.” The council was created in 2009 but given no say over the pending dual tunnels plan. The state was pushing a grand program called the Bay-Delta Conservation Plan. However, the BDCP was abandoned in 2015 in favor of two new, independent programs: EcoRestore and California WaterFix (popularly known as the twin tunnels). Rather than adopt a new policy on conveyance, the council...

Drought Contingency

Motivated by the recent drought, local water agencies have formed an unprecedented partnership aimed at reducing the impact of future dry spells. The Bay Area Regional Reliability partnership consists of eight of the region’s larger water districts. “For the first time in the history of water deliver in the Bay Area, the water utilities are talking about how to assist each other when there is a shortage.”

High Road for the Wettest Highway?

As Bay Area cities and counties grapple with the formidable challenge of preparing for a higher San Francisco Bay, there is perhaps no better example of the obstacles and opportunities than the effort underway to adapt Highway 37. The 21-mile North Bay corridor running from Vallejo to Novato has long been a source of tranquility and frustration. The highway offers sweeping views of tidal baylands dotted with roosting waterfowl and shorebirds plumbing mudflats for food, along with mile-upon-mile of open...

Advocates for Alameda Creek are concerned that a new proposal to beef up passenger rail service between Stockton and San Jose would jeopardize water quality and wildlife habitat.

Niles-based Alameda Creek Alliance says the proposed expansion of the Altamont Corridor Express (ACE) passenger rail service might also bring increased freight train traffic to narrow, steep Niles Canyon, creating a situation that could lead to possible derailments and creek-contaminating spills. (A passenger train derailed into the creek in 2016.) Niles Canyon is the critical mid-point of complex watershed-wide work to reduce erosion, improve flood control, and restore steelhead to the creek. The Alliance and others are asking for a...

LA Drainage Goes Native

Community Conservation Solutions is piloting a new analytical tool that not only taps an untapped local water supply — the 969 miles of metropolitan storm drains in Los Angeles — but also has the metrics to earn carbon credits for doing so. “It’s very practical, you just stick your straw in the local water source rather than pumping it into the city from hundreds of miles away,” says the NGO’s director Esther Feldman. The tool helps land and water managers prioritize projects...

Corte Madera’s Flood Fight Goes On and On

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.

EBMUD Experiments With Pipe Replacement

On average, underground water distribution pipes can last about 100 years. The East Bay Municipal Utility District (EBMUD) owns and maintains roughly 4,200 miles of them. And it replaces about ten miles per year. At that rate it would take four centuries to replace the whole system: an approach one could charitably call unsustainable even if all the pipes were brand-new today. But parts of EBMUD’s system, cast-iron pipes inherited from forgotten, now-defunct water agencies, date to the late 1800s.

Two-Way Threat to Intakes and Outfalls

San Francisco’s vulnerability to sea level rise is no secret. Entire neighborhoods are built on fill, only feet above current sea level. But just like Treasure Island and the rapidly developing Mission Bay neighborhood, less visible parts of the city — the pipes and plants that collect, treat, and whisk away San Francisco’s stormwater and sewage — are also at risk. And this critical infrastructure could face a double hit from climate change in the coming decades: more severe storms...

Beyond the Bag Ban

The other day I found myself turning out the closets for one last plastic bag. Dreaming of those white Safeway sacks as I searched for something to sequester what may well be the most toxic contaminant in the homes and cars of many a modern family: freshly used soccer cleats. But a year into San Francisco’s bag ban, there just aren’t that many plastic shopping bags around our house anymore. All told, 60 percent of municipalities in the four most...

Alameda Work Trickles On

Alameda Work Trickles On by Ariel Rubissow Okamoto Driving down 680 from San Ramon to Pleasanton — with its prettily paved and groomed burbs — you wouldn’t guess that this was once a shallow lake and willow marsh. Indeed little trace
is left of the vast freshwater swamp called Tulare Lake, just over the East Bay ridges, which once collected all the runoff from Livermore and San Ramon.
