As Rising Seas Disrupt Toxic Sites, Communities of Color Are at Most Risk

As rising seas threaten to flood hundreds of toxic sites along the California coast, the risk of flood-related contamination will fall disproportionately on the state’s most marginalized communities, finds a new study published Tuesday by researchers at UC Berkeley, UCLA and Climate Central. San Mateo and Alameda counties are projected to host the most at-risk hazardous sites by 2050, but by 2100, Orange County is projected to surpass both as oil and gas wells there and in Los Angeles County face rising coastal flood risks.

As rising seas threaten to flood hundreds of toxic sites along the California coast, the risk of flood-related contamination will fall disproportionately on the state’s most marginalized communities, finds a new study published Tuesday by researchers at UC Berkeley, UCLA and Climate Central.

San Mateo and Alameda counties are projected to host the most at-risk hazardous sites by 2050, but by 2100, Orange County is projected to surpass both as oil and gas wells there and in Los Angeles County face rising coastal flood risks.

Under California’s high-risk aversion scenario, which projects that sea levels could rise by more than 6 feet by the end of the century, the study identified 736 facilities at risk of coastal flooding and an additional 173 with projected groundwater encroachment.

Residents living within 1 kilometer of at-risk sites were more likely than others to be people of color, to be living below the poverty line, to be unemployed or to experience another form of social disadvantage such as linguistic isolation.

As part of the study, the researchers also released a new interactive online tool in English and Spanish that allows users to map toxic sites that are at risk of coastal flooding, either by county or by individual facility.

Users can also overlay indicators of nearby residents’ social vulnerability, including the percentage of people who are living below the poverty line, who are experiencing unemployment, or who don’t have a high school degree.

“Sea level rise is like a slow-moving storm that we can anticipate and prepare for,” said Rachel Morello-Frosch, a professor of public health and of environmental science, policy and management at UC Berkeley and senior author of the paper. “As California invests in community resilience to climate change, it is essential that considerations of environmental justice are at the fore.”

Low-income communities and communities of color already face disproportionate exposure to myriad environmental pollutants, and the threat of additional exposures from sea-level rise will only exacerbate these inequities.

Compared to their neighbors, socially vulnerable residents can also face more challenges to evacuate during a flood and often experience social stressors that can make them more susceptible to the health impacts of pollutant exposures.

“Again, climate change amplifies inequality,” said lead author Lara Cushing, an assistant professor of environmental health sciences at the UCLA Fielding School of Public Health. “Sea level rise will present additional risks of contaminant releases to communities already living with pollution sources in their backyards.”

The study was conducted as part of the Toxic Tides project, which brought together a multidisciplinary research team with community advocacy organizations to understand how rising seas would impact hazardous sites, including refineries, industrial facilities, sewage treatment plants and cleanup sites.

The team released a preliminary set of data and an earlier version of the online mapping tool in November 2021; the new, peer-reviewed study, which appears in the journal Environmental Science and Technology, includes additional analysis about the environmental justice implications of the findings.

On June 4, a national nonprofit named the Equity in Infrastructure Project (EIP) – which aims to increase public construction contracting opportunities for small and historically underutilized businesses – held a day-long event in downtown San Francisco to rally supporters and build momentum to its cause.

It was attended by more than 100 individuals from public agencies, private firms, and other organizations committed to increasing contracting opportunities with governmental agencies, thereby creating more competition and lowering public costs.

The EIP event was held the Hyatt Regency San Francisco in conjunction with BuildIT, which aims to increase contracting opportunities for LGBT-owned businesses.

At the event, 16 entities signed the EIP pledge, vowing to take steps to increase public contracting opportunities in their spheres for small and historically underutilized businesses.

The pledge signees included Hub International, the Port of San Francisco, the San Francisco Public Utilities Commission, California High-Speed Rail Authority, the Port of Oakland, Robert Graham of Webcor Builders, Holder Construction, the Weitz Company, Sky Blue Builders, Hornblower, Swinerton, Luster National, Talson Solutions, Center for Community Wealth Building, and the Construction Contractors Alliance.

Following the workshop, BuildIT hosted a VIP evening reception honoring EIP, whose principals – Phil Washington, John Procari, and Rick Jacobs – accepted the award.

The event also set in motion the coalition’s efforts to implement recommendations from EIP’s “Procurement for Prosperity: A Playbook.”

The Playbook is a practical guide for public agency leaders and procurement and contracting practitioners to grow the capacity of small and first-time contractors, strengthen competition, and deliver better value for taxpayers.

Toks Omishakin, Secretary of the California State Transportation Agency (CalSTA), a long-time EIP supporter, also told attendees, “This is about commitment.  This has been a life’s work. This is a tailwind moment.”

The event’s presenting sponsor was Hub International, one of the largest insurance brokerages in the nation, which was joined by partners Travelers Insurance and the State Compensation Insurance Fund.

After the pledge-signing ceremony, attendees participated in a workshop in which they examined the policies, practices, and programs needed to meet EIP goals, learned from practitioners, and identified next steps toward utilizing the Playbook.

Ingrid Meriwether, formerly of Merriwether & Williams Insurance Services (MWIS) and current president of Hub International’s Aligned Risk Management, MWIS, described the hard-fought lessons she and her MWIS team have learned over the last three decades administering contractor development programs (CDPs) for the City and County of San Francisco, Alameda County, City of Los Angeles, LA Metro, and other municipalities.

The CDPs help small and local construction firms win public infrastructure contracts with these government agencies.  The program provides bonding assistance, contract financing, technical support, training, and other services to underrepresented businesses funded by public agencies who seek greater contracting participation with these firms.

Merriwether said programs like these “break down systemic barriers, create greater fairness, and save taxpayers money by enabling more competition.  The contractor development programs have, cumulatively, over two decades, helped contractors access over $1 billion in bonding, supporting over $380 million in awarded contracts, and maintaining a loss ratio 250 times lower than the industry average – while saving participating municipalities more than $27 million in contracting costs as a result of enabling more competition.”

Rick Jacobs, EIP co-founder and co-chair urged attendees make plans to meet again in the near future “to continue building on this work, share progress on organizational commitments, and discuss how we can collectively advance the goals of the EIP pledge.”

Oakland Museum Presents Landmark Retrospective Celebrating Beloved Bay Area Artist Mildred Howard

“Poetics of Memory” coincides with a year of major recognition for Howard. In 2026, she received the California Arts Council’s 50th Anniversary Award, honoring artists whose work has shaped California’s cultural and civic life, as well as the Museum of the African Diaspora’s Artist Impact Award. In 2025, she was awarded a prestigious Guggenheim Fellowship in recognition of her transformative contributions to American cultural life.

The Oakland Museum of California (OMCA) opened “Mildred Howard: Poetics of Memory,” the first major museum survey of Bay Area artist Mildred Howard, on June 12.

The exhibition spans five decades of Howard’s influential work, bringing together immersive installations, found-object sculptures, archival materials, and new commissions that explore memory, identity, and power in American life.

“Poetics of Memory” coincides with a year of major recognition for Howard. In 2026, she received the California Arts Council’s 50th Anniversary Award, honoring artists whose work has shaped California’s cultural and civic life, as well as the Museum of the African Diaspora’s Artist Impact Award. In 2025, she was awarded a prestigious Guggenheim Fellowship in recognition of her transformative contributions to American cultural life.

Howard was born in San Francisco in 1945 and raised in the East Bay, where she went on to study Afro-Haitian dance, make and sell clothing, and experiment with collage and sculpture.

Her multimedia art practice emerged from these experiences, later becoming associated with West Coast conceptual art, San Francisco funk, and a vibrant community of artists like Oliver Jackson, Betye Saar, and Raymond Saunders. Since the 1970s, she has used found materials and family stories to explore memory—both individual and collective.

At OMCA, visitors enter “Poetics of Memory” through a series of intimate galleries featuring Howard’s early mixed-media pieces and sculptures, along with a large video projection of a number of her public artworks.

Together, they emphasize Howard’s interest in everyday objects as powerful carriers of individual and shared stories. Highlights include collages that remix images of the artist herself; found-object sculptures like The History of the United States with a few Parts Missing (2007) that address omissions in dominant narratives; and public works like “Locks and Keys for Harry Bridges” (2001) that transform urban space into a meditation on access and labor.

This culminates in a richly detailed “studio” environment, where works in progress, archival exhibition flyers, historic photographs of Howard and her community, postcards from fellow artists, and other materials offer insight into her creative process and daily life.

The exhibition then opens into a high-ceilinged, dramatically lit space that brings together Howard’s signature immersive installations. On one end, “Crossings” (1997/2026) – a field of hundreds of ceramic eggs leading to an ornate mirror – suggests cycles of birth, motherhood, and transition, while drawing on the emotional echoes of the Middle Passage. On the other end, “Blackbird in a Red Sky” (a.k.a. “Fall of the Blood House”) (2002) – a red glass shack bordered by a pond – also uses reflection and transparency to draw viewers into the work and prompt consideration of themes of identity and home.

Howard’s newest video installation, “Moving Stills” (2026), repurposes never-before-seen family footage she took as a teenager on a train trip to the American South. Projected onto cascading layers of translucent fabric that stretch across an entire gallery wall, the piece immerses viewers in a layered meditation on memory, migration, and time.

The “Mildred Howard: Poetics of Memoryexhibit will be on display through Oct. 11 at the Oakland Museum of California, 1000 Oak St., Oakland, CA 94612. Museum hours are Wednesday through Sunday, 11 a.m. to 5 p.m., with extended hours on Fridays to 9 p.m.

Starting July 1, the standard adult fare for the San Francisco Bay Ferry route between Richmond and San Francisco will increase to $5.20, up from the current $4.90.

Discounted fares for eligible passengers, including youth, seniors, people with disabilities, and Clipper START users, will rise to $2.60 from the current $2.40. Children under 5 will continue to ride for free.

The Oakland and Alameda routes will increase from $4.90 to $5.10, the South San Francisco route will go up from $7.40 to $7.60, and the Vallejo route will increase from $9.90 to $10.

The adjustments are part of a systemwide fare update approved by the agency’s Board of Directors, which is moving away from a flat 3% annual increase to route-specific pricing for the 2027 and 2028 fiscal years.

This fare update arrives as San Francisco Bay Ferry celebrates a historic May, transporting 301,270 passengers. The record-breaking figure represents an 8% increase over May 2025 and marks the third consecutive month of record-setting ridership.

Furthermore, it is the sixth month in a row that passenger numbers have exceeded pre-pandemic levels. Weekend travel has been a primary driver of this growth, with average weekend ridership seeing a 56% increase compared to pre-pandemic trends.

The agency states that the fare adjustments are necessary to ensure the long-term fiscal sustainability of public ferry services. By shifting to route-specific adjustments, the agency aims to offset rising operating costs while maintaining the high levels of service frequency and reliability.
