Flows and Ecosystem Function Dominate Delta Plan Amendment

With the Delta lagging behind the Bay on four of the State of the Estuary Report’s five indicators, the last long-range plan for restoring its ecological health abandoned, and the threats from climate change becoming ever more alarming, the need for a new regulatory vision for the region may never have been greater. A pending amendment to the Delta Plan, shared by Ron Melcer at the State of the Estuary Conference as part of a policy update session, is meant to provide that vision and the strategies to achieve it. The amendment — to Chapter Four of the Delta Plan, which focuses on the Delta ecosystem — was developed in response to the state’s pivot away from the 2013 Bay-Delta...

State Plan Doubles Down on Alignment

The California Water Plan Update 2018—released by the Department of Water Resources in July—is meant to guide state policy and investment over the next 50 years to maximize the benefits squeezed out of every drop of the water supply. The timing of Update 2018 is fortuitous: In April, Governor Newsom ordered the California Natural Resources Agency, California Environmental Protection Agency, and California Department of Food and Agriculture to develop a portfolio of water resilience strategies.

Bay-Delta Leaders Comment on Climate

These magazine pages share the opinions of various new leaders in the Estuary management world about climate change. “The biggest challenge is that it is difficult for people, including decision-makers, to plan for uncertain, long-range challenges. We know that in order to make the greatest impact we need to start now,” says BCDC’s Dana Brechwald.

Permitting Opens a Fast Lane

“Innovating in government is easiest done when there are incentives,” says Brad McCrea of the Bay Conservation and Development Commission. The Bay Restoration Regulatory Integration Team, which begins accepting applications this fall, has been designed to accelerate the pace at which large-scale projects find their path to funding through the daunting thicket of permit applications and regulatory approvals.

Joaquin Esquivel is impatient with the narrative that has dominated California water policy for decades, especially when it comes to the Delta and the eternal tug-of-war between farms, cities and the environment.

“For so long in the water space you’ve had these false dichotomies where you are being told you have to choose one or the other,” says Esquivel, who Governor Gavin Newsom appointed Chair of the State Water Resources Control Board in February. “These narratives can fuel themselves, they take root in communities, but they don’t really do much to get to the heart of the policy question.” A native of the Coachella Valley, Esquivel served on the State Board for two years prior to his appointment. He cites literature as a particular passion, and had planned on a career in academia before a college internship in former Senator Barbara Boxer’s Washington, D.C. office turned into a full-time job. “What I...

Susan Tatayon wants to bridge the emerging communication gap between Delta science and policy.

While Tatayon, who was installed as Chair of the Delta Stewardship Council in January, sees good communication efforts on the part of council scientists and staff, not everyone on the receiving end gets their drift. “What I’m learning from some council members and others is that they don’t understand the connection between the science being done and the policies they want to make.” Tatayon assumes her new position after a career that includes stints at The Nature Conservancy, the U.S. Bureau of Reclamation and the Department of Water Resources. It was at DWR as a young staffer in the Department of Planning that Tatayon discovered her interest in environmental protection: “I was assigned to read impassioned letters about saving Mono...

Purse Opens for PCA Projects

Marsh restoration, Bay and Ridge Trail extensions, and urban park upgrades are among the types of projects eligible to receive funding through the 2019 Bay Area Priority Conservation Area (PCA) One Bay Area Grant Program. By March, aided by new mapping tools that can pinpoint regional landscape characteristics and needs, more than 36 cities, counties, agencies and non-profits had submitted letters of interest to the program, outlining a variety of projects that benefit one or more of the Bay Area’s 165 PCAs (see map opposite). Altogether, the grant requests totaled more than $19 million. Some of these projects may help vulnerable shoreline areas defend against sea level rise; others may make urban hardscapes more porous under atmospheric river downpours; still...

Choppy Waters for Flow Rules

The winter kicked off with the State Water Resources Control Board’s December vote to adopt increased flow objectives for the southern Delta. The vote provoked an immediate volley of lawsuits, both from water users and from environmental organizations. “Governor Newsom has staked out turf against the Trump Administration,” says San Francisco Baykeeper’s Jon Rosenfield...

State Could Step Up

Despite an official California policy in place since 1992 that calls for “no net loss” of wetlands, the lack of a specific wetlands definition has led to the loss of many thousands of acres of ecologically important lands. That could change soon, thanks to an update from the State Water Resources Control Board expected out soon after more than a decade of work. California environmentalists are optimistic that the updated policy, titled “State Wetland Definition and Procedures for Discharges of Dredged or Fill Material to Waters of the State,” will move quickly toward adoption by the state board in early 2019.

Just months after becoming the first project awarded Measure AA funding, the first phase of tidal breaching at the Montezuma Wetlands restoration project will be two-thirds complete by the end of November.

“We are on track to complete the levees and transition zones next year so we can breach into the slough and restore the area to tidal action,” says Jim Levine, managing partner of Montezuma Wetlands LLC, which owns the property. The breach of the first major restoration area is planned for December 2019. This phase of the multi-phase project will restore 600 acres of previously subsided shoreline on the eastern edge of Suisun Bay to tidal, seasonal and some sub-tidal habitat. “A lot of threatened and endangered species habitat is going to be provided just by Phase One of this really large effort,” says the Coastal Conservancy’s Laura Cholodenko. The swift progress follows nearly two decades of preparation, during which Montezuma...

In response to the critical threat that changing ocean chemistry poses to both ecosystems and economies, the California Ocean Protection Council adopted the state’s first Ocean Acidification Action Plan on October 25.

The plan addresses ocean acidification—like climate change, a consequence of rising atmospheric CO2 levels—in the context of other threats such as polluted runoff, warming temperatures, and rising seas. It promotes local solutions that are likely to provide multiple benefits—from improving water quality to promoting healthy seagrass, marsh, and kelp forest habitats. The plan, one of the first released by a member of the International Alliance to Combat Ocean Acidification, identifies six key strategies, and outlines five-year goals and actions for each. “We hope this plan can serve as a model for other jurisdictions that are looking to address ocean acidification and global ocean change through concrete and targeted local, regional, multidisciplinary and scalable activities,” says the Council’s Jennifer Phillips.

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.

A new online portal from the Delta Stewardship Council offers everyone from scientists to tourists an accessible window into the Delta’s identity and importance.

“Although I had studied freshwater and marine ecology, I really was not familiar with the Delta before I started working there,” says 2017 Sea Grant Fellow Heidi Williams, who developed the Beginner’s Guide to the Sacramento-San Joaquin Delta. “I was looking for a way to dive in and learn about the Delta and realized that there wasn’t an easily accessible place to turn for the basics.” As a science communications fellow, Williams suggested to the Council that she create one herself, and spent the next year immersed in Delta-related articles and other materials. “I realized that this needed to be more up-to-date than a lot of that material because a lot of science and politics have changed and progressed in...

Vital and Vulnerable? Delta Contemplates Climate Change

With its pivotal role in California’s ecology and economy, the Delta’s ability to adapt successfully to climate change and sea level rise will have an enormous influence on how well the state as a whole adapts. “Most of the climate vulnerability work in the Delta so far has focused on water resource management, not the array of other potential impacts,” says Delta Stewardship Council’s Kate Anderson. In May, the Council issued an RFQ for an assessment of the Delta’s potential climate vulnerability. It also joined forces with BCDC’s Adapting to Rising Tides...

South Bay: Swaps and Sponges Create Absorbing Vision

East Palo Alto is a microcosm of Silicon Valley’s most pressing social and environmental issues. Home to low-income communities, the city faces rising rents and the displacement of longtime residents. As one of the lowest-lying communities in the Bay Area, it is also ground-zero for sea level rise in the South Bay. Although located at the northern end of Resilient by Design’s Field Operations Team’s 20-mile shoreline jurisdiction, much of their public engagement effort was focused on East Palo Alto. “This scale of work needs an enormous amount of public support,” says Field Ops’ Richard Kennedy of their ambitious plan to use a network of marshland, salt ponds, and tidal wetlands to “sponge” the effects of sea level rise from...

Updated guidance synthesizing the best available science on sea-level rise projections and rates for California—including advances in modeling and improved understanding of the potential impact of ice loss from the Greenland and Antarctic ice sheets—is now available from the California Ocean Protection Commission.

The State of California Sea-Level Rise Guidance 2018 Update is the second update to guidance originally released in 2010. It is based on the scientific findings of the OPC Science Advisory Team’s 2017 report, “Rising Seas in California: An Update on Sea-Level Rise,” which noted among other findings that California may be particularly vulnerable to sea level rise stemming from ice loss in Antarctica. The guidance “provides a bold, science-based methodology for state and local governments to analyze and assess the risks associated with sea-level rise, and to incorporate sea level rise into their planning, permitting, and investment decisions,” says OPC’s Jenn Eckerle. “It provides a step-by-step approach for state agencies and local governments to evaluate sea level rise projections...

Napa County voters will weigh in on the fate of the county’s remaining oak woodlands this June, when they cast ballots on Measure C, the Watershed and Oak Woodland Protection Initiative.

“Ninety-five percent of oaks on the valley floor are gone and we want to do a better job reducing deforestation on the hills” initiative co-author Jim Wilson, told the Bay Area Monitor. “Our hillsides are beautiful and also filter rain, keeping water clean as it replenishes aquifers.” Most of Napa’s oak woodland loss is due to vineyard development, and the county General Plan projects that another 3,000 acres of woodland will be converted to vineyard by 2030. Current protections require that two replacement oaks be planted or preserved for every mature tree felled, and oaks on slopes steeper than 35 percent and in riparian forests along streams are protected. Measure C would increase the replacement requirement to three trees for...

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.

A wide-ranging Habitat Conservation Plan that could eventually protect up to 4800 acres of endangered species habitat in the Bay Area is the linchpin of a November agreement between the U.S. Fish and Wildlife Service and Pacific Gas and Electric Company.

Under the agreement, FWS issued the utility a 30-year incidental take permit for operations and maintenance activities in the nine Bay Area counties. The HCP includes strategies to avoid, minimize, and offset potential direct, indirect, and cumulative effects of PG&E’s O&M and minor new construction activities on 32 threatened or endangered species. The parties are hailing the landscape-scale plan as an improvement over the project-by-project process they previously operated under, as it will enable PG&E to complete projects more quickly while protecting more land for mitigation and increasing opportunities for passive recreation such as hiking and bird watching. However, some environmental groups are concerned that the plan does not cover several species that should have been included. In addition, says...
