Why Caltrans is widening a Bay Area highway that’s going to flood

The highway stretches across Marin and Solano Counties through the colorful mosaic of marshland in the San Pablo Bay north of San Francisco. But state Route 37’s scenic roadway is vulnerable to sea level rise, which could submerge the highway as soon as 2040, and is subject to brutal bottlenecks during peak hours as commuters circulate between counties. The doomed Bay Area highway that sees over 40,000 drivers a day has a fix in the works — but not everyone agrees it’s the right one. As shovels and bulldozers from Caltrans prepare to widen Highway 37 in a $500 million project, tides continuously chip away at the road’s edge. Its western half near Novato is subject to repeated flooding, especially during king tides, while the eastern span is protected by a series of levees and dikes. ​​

The legendary Delta Breeze: Yes, it’s a real thing

… Delta residents love to share their experiences with this summertime weather phenomenon, in all its complexities, and how it affects their daily activities and even their life choices. “The Delta Breeze is a real thing,” says Iva Walton, Isleton’s mayor. The breeze originates in the Pacific Ocean, more than 50 miles away, and meteorologists and atmospheric scientists say it can bring a few degrees of relief on hot days to the millions of people who live, work and play in the Delta, a region that extends from Vallejo to Sacramento and Stockton. … As inland temperatures rise, the currents push in through two major openings in the coastal range: the Golden Gate and the Petaluma Gap, lowlands that run between Bodega and Tamales bays and Petaluma. From San Francisco and San Pablo bays, the cool air travels up through the Carquinez Strait, usually arriving in the Delta in the late afternoon.

Friday Top of the Scroll: Newsom’s plan to give water agencies more leeway in meeting rules moves forward

California regulators are supporting a controversial plan backed by Gov. Gavin Newsom — and opposed by environmental groups — that would give water agencies more leeway in how they comply with water quality rules. The Newsom-backed approach is included as part of a proposed water plan for the Sacramento-San Joaquin River Delta, released by the State Water Resources Control Board on Thursday. The plan would give water agencies two potential pathways to comply with water quality goals — either a traditional regulatory approach based on limiting water withdrawals to maintain certain river flow levels, or an alternative approach supported by the governor in which water agencies, under negotiated agreements, would make certain water flow commitments while contributing funding for wetland habitat restoration projects and other measures.

Trump EPA commits to ‘100% cleanup’ of badly polluted Tijuana River

Environmental Protection Agency Administrator Lee Zeldin committed the Trump administration to “a permanent, 100% solution to the decades-old Tijuana River sewage crisis” in a new agreement signed with Mexico on Thursday. … According to the agreement, Mexico will shake loose $93 million in money it previously committed, known as “Minute 238 funds.” Deadlines for several long-discussed improvements will also come sooner — some this year — it says. One example is the 10-million gallons per day of treated effluent that currently flows into the Tijuana River from the Arturo Herrera and La Morita wastewater treatment plants and will now go to a site upstream of the Rodriguez Dam, southeast of Tijuana. … The MOU also commits the two countries to taking into account Tijuana’s growing population, to make sure that infrastructure improvements are not outstripped by changes on the ground.

Western lawmakers move to improve Colorado River snow monitoring

Western lawmakers, including U.S. Sen. John Hickenlooper of Colorado, want to know — exactly — how much snow and water is in the Colorado River Basin. The legislators Thursday introduced a bill focused on improving how the basin measures its water supply. … The bill highlights focus areas for the program, like being more responsive to changing weather and watershed conditions, informing water management decisions at local up to interstate levels, and building the program’s capacity so it can adapt to new forecasting and measurement capabilities. The bill would also support different measurement technologies like imaging spectroscopy, machine learning, and integrated snowpack and hydrologic modeling. It would increase the program’s budget from $15 million over five years to $32.5 million over five years.

Project Blue hammered over water & power use for planned Tucson data centers

Tucson city officials and the developers of Project Blue — a planned complex of data centers for Amazon — faced a fractious crowd hundreds strong Wednesday night as they attempted to make their case the project will be “water positive” and will not drive up electric rates, while trying to defend non-disclosure agreements that still keep information from the public. … During the first two years, the project will use drinking water for cooling, but will switch to reclaimed water. … At one point, a speaker asked [Tucson City Manager Tim] Thomure how they would enforce the two-year promise to halt using drinking water, noting that the draft agreement includes caps but breaking those caps won’t mean the city cuts off the water supply; instead, the city will just add extra charges.

Can low-profile state health researchers fill a gap after Trump EPA cuts?

In the wake of the Trump administration’s decision to dismantle the research arm of the U.S. Environmental Protection Agency, a robust if little-known California agency known as the Office of Environmental Health Hazard Assessment is poised to take on an even bigger role to bridge the gap. … Experts said the decision to break up the research office sends a chilling signal for science and will leave more communities exposed to environmental hazards such as industrial chemicals, wildfire smoke and per- and polyfluoroalkyl substances — or PFAs — in drinking water, all of which are subject to the department’s analysis. … Kris Thayer, OEHHA’s director, came to agency from ORD, where she directed its IRIS program for identifying and characterizing the human health hazards of chemicals. She said the state is “absolutely going to be looking at every way that we can fill the void given our resources, but we are going to feel the pinch of this.”

Colorado lags behind in issuing water stream-protecting permits

Colorado lags far behind neighboring states when it comes to keeping special permits critical to stopping pollutants from entering streams current, a new report says. Colorado’s backlog has, at times, surged to 70%, while six other states surveyed have fairly few lapsed wastewater treatment permits, according to the report, with Arizona and Oregon, for instance, showing permit backlogs of just 10%. The analysis was commissioned last year to help the Colorado Department of Public Health and Environment and state lawmakers understand why the situation has deteriorated and how it can be fixed. … Colorado lawmakers approved $6 million in new funding in 2023 to help the CDPHE’s Water Quality Control Division hire more people to help process permits more quickly and efficiently, but the backlog remains and affects major treatment facilities.

News release: DWR releases draft best management practices on managing land subsidence in California

For almost a century, parts of California have been gradually sinking, impacting critical infrastructure and the communities who rely on it. Recognizing this challenge, the Department of Water Resources has released a draft Best Management Practices document for public comment that will help local water agencies address this growing concern and support groundwater reliant communities. … Once finalized following public review, the document will serve as a guide for groundwater managers on the basics of subsidence, how to best manage it, and available technical assistance. This document does not replace any existing, local, state, or federal regulations, but serves as a resource that local agencies can add to their water management toolkit.

‘Biggest, baddest’ rainfall events are getting worse

… Flash floods have wreaked havoc across the country this summer, transcending geography, topography and the built environment from the rural Southwest to the largest cities in the Midwest and Northeast. … These heavy precipitation events are among the clearest symptoms of climate change, scientists say. Copious studies warn that they’re already happening more often and becoming more intense, and they’ll continue to worsen as global temperatures rise. … But in recent years, scientists have noticed an alarming trend. Extreme storms in some parts of the world appear to be defying the Clausius-Clapeyron relation, producing far more rainfall as temperatures rise than the equation would predict. … It’s a phenomenon scientists have dubbed the super-Clausius-Clapeyron rate. Researchers are still investigating the reasons it’s happening.

Small Northern California community gets clean drinking for first time in decades

After years of uncertainty and relying on bottled water, residents in the small rural community of Robbins are finally seeing progress toward a permanent solution for safe, clean drinking water. Construction is now underway on a new well and water treatment facility, part of a sweeping overhaul of the town’s aging water system. Robbins, located in Sutter County and home to roughly 300 people, has struggled for decades with contaminated tap water that didn’t meet state or federal safety standards. … The $8 million project is funded by a grant from the California State Water Resources Control Board’s SAFER program. The investment is being used to upgrade key parts of the town’s water infrastructure, with three major construction sites now active.

The LA River tests positive for harmful ‘forever chemicals’ in 41 of 45 samples

… In Los Angeles, 41 of 45 samples collected from 17 rivers and tributary sites contained multiple types of forever chemicals. … The Waterkeeper Alliance report shows that wastewater treatment plants and places where treated sewage sludge, known as biosolids, is spread on land as fertilizer, such as the LA-Glendale Water Reclamation Plant, are major sources of PFAS pollution. … There are new city-wide developments that may make a difference when it comes to water treatment. The Los Angeles Department of Water and Power (LADWP) is constructing a massive water infrastructure project near the LA River. … While the project doesn’t specifically reference PFAS, experts note that large-scale recycling treatment upgrades like this could significantly limit public exposure to PFAS by filtering them out.

Great Salt Lake is back on the decline. It’s also receiving $53M to help save it

The Great Salt Lake is in the middle of its summer decline, bringing its levels back down to a concerning section within the state’s management plan. Its southern arm is now down to 4,192.2 feet elevation, losing about 1½ feet since its peak this spring, while its north arm remains just below that, at 4,191.8 feet elevation, according to federal data. Levels begin to create “serious adverse effects” on brine shrimp viability, air quality, mineral production and recreation at 4,192 feet elevation, the state plan warns. However, the lake is also receiving a significant financial boost amid ongoing efforts to get water back to the lake. Up to $53 million in grant funding is now available for projects that support the Great Salt Lake and its wetlands, state officials announced on Wednesday.

Federal oil and gas lease changes ‘gut public lands,’ Colorado advocates say

After a proposed provision in the recent Republican tax break and spending cut law that would have opened up millions of acres of federal lands for sale was axed, Colorado climate leaders and public lands advocates still didn’t have much to celebrate. That’s because the massive federal policy bill‘s surviving provisions governing oil and gas leasing on federal lands are “an egregious step back for the environment,” according to Melissa Hornbein, a senior attorney at the Western Environmental Law Center. … Allison Henderson, the southern Rockies director for the Center for Biological Diversity, said this provision poses a “significant risk” to the environment, water supplies and vulnerable species of animals that live on public lands, because resource management plans “do not provide kind of the nitty-gritty, site-specific types of mitigation measures that are necessary.”

Opinion: What to do with all that ‘Pure Water’?

… These days, the focus is less on San Diego’s access to water — the envy of water managers everywhere — but on its astronomical costs. Further, what some of the visionaries didn’t foresee is the region would be stuck with way more water than it needs. Unloading it has proved a vexing problem. And a lot more is coming with the city of San Diego’s Pure Water recycling project — which could produce the region’s costliest water yet — and other emerging water reuse programs, such as one in East County. … One glimmer of hope to take the edge off the increases: emerging changes in the byzantine legal and political dynamics of California’s water world, which could open up markets for San Diego water. Oddly enough, some local officials are hoping a prime customer will be their former nemesis, the Los Angeles-based Metropolitan Water District of Southern California.

Opinion: Salmon fishing in the valley

… As the salmon runs have declined for many reasons, one of the strategies to reduce salmon smolt mortality has been trucking the juvenile salmon to the delta to bypass the striped bass. Stripers are spawning in the Sacramento River during the spring salmon out-migration. Stripers love to eat baby salmon. As with many things in life, the solution to today’s problem is often the cause of the next issue. Trucking the juvenile salmon directly from the hatchery on Battle Creek to the lower delta or the bay does not allow the salmon to imprint on the Sacramento River water. These fish did not know their way home. The result was salmon wandering to freshwater creeks flowing into the bay. … The solution to this has been to set net pens in the Sacramento River to hold these Coleman salmon smolts for a period of time to imprint on the water. Then they are trucked down to the delta or bay.

AB 306: California environmental groups vent concerns over building standards law

Building new housing is a priority across the state, especially in fire ravaged areas of Southern California. But now a growing number of environmental groups say they want to make sure that future construction isn’t putting communities at risk from climate change. They’re pointing to a provision in a recently passed budget bill, AB 306, which could essentially freeze new residential building regulations for the next six years and bars cities and counties from adopting stricter codes. David Lewis is executive director of the nonprofit Save the Bay. His group is concerned that the bill will slow climate resiliency efforts, including upgrades meant to protect communities from flooding and other effects of sea level rise.

No NEPA, ESA reviews needed for California water contracts, court rules

A federal judge declared in a new ruling that the Bureau of Reclamation can issue permanent water agreements to major contractors in California — specifically the sprawling Westlands Water District — without undertaking new environmental or Endangered Species Act reviews. But conservation advocates who brought the lawsuit against the Westland contract said that it does not clear the path forward for that deal, pointing to a series of claims still pending in the U.S. District Court for the Eastern District of California. District Judge Jennifer Thurston, a President Joe Biden appointee, issued a decision in favor of the Interior Department on June 30, and subsequently ordered the case, Center for Biological Diversity, et al., v.

Amazon named as company behind 290-acre data center campus in Tuscson, Arizona

Cloud giant Amazon Web Services (AWS) has been named as the end customer for a planned data center campus in Tucson, Arizona. Project Blue is a 290-acre site set to host a data center campus. At least three data centers are reportedly set to be built, but the final number of buildings could be higher; some reports suggest up to 10 buildings totaling 2 million sq ft (185,805 sqm) and 600MW are planned. … A new opposition group, No Desert Data Center, is attempting to mobilize residents against the project over its water use and potential impact on the area. The site is reportedly set to use drinking water for its cooling systems for at least the first two years of operation until it can switch to using treated wastewater once a new water line is completed.
