Antioch (94509 & 94531) Climate Action & Advocacy

The City of Antioch, CA

Antioch Climate Action & Advocacy brings together the city’s story of challenge and resilience—past, present, and future. On this page, you’ll find a close look at Antioch’s unique divides, social and economic pressures, and the urgent need for coordinated climate action. Read on to learn what’s at stake, how local initiatives are responding, and what you can do to support a healthier, more sustainable Antioch.

The city of Antioch, sometimes referred to as “the Gateway to the Delta”, is one of California’s oldest towns. It was founded in 1849 as Smith’s Landing, then renamed Antioch.  It is now a diverse, growing city of nearly 120,000 residents. 

As a more affordable enclave of the expensive SF-Bay Area, the city experienced booming growth during the 1990s.  It is now starkly divided between “Old Antioch” (94509) and “New Antioch” (94531).

Old Antioch is the Rivertown industrial area north of Route 4, on the banks of the San Joaquin River. New Antioch is the area south of Route 4, filled with sprawling new homes, nearby shopping centers, big-box stores, and restaurants.

During the late 2000s, at the height of predatory lending, Antioch became the “unofficial foreclosure capital” of the Bay Area. This hit older neighborhoods hard, forcing long-term residents from their homes and resulting in a loss of community stability. It also widened the gap in property values and school performance between the two Antioch regions.

Newer developments in the south attracted large retail chains and higher-income residents. Unfortunately, North Antioch still struggled with the decline of its original industries.

Antioch’s Transportation Challenge & Infrastructure Gap

Antioch sits along the increasingly congested Highway 4, which has not kept pace with the exploding weekday traffic from its growing population. Route 4 feeds into freeways connecting Concord, Walnut Creek, and beyond to the West. Most Antioch residents face long workday commutes. This is constant, whether they take BART toward San Francisco, drive west, or head south to Livermore, Silicon Valley, or the South Bay.

Last Stop for BART

Even though residents paid taxes for mass transit development for years, the Antioch BART extension lagged behind other Bay Area communities. The Antioch station finally opened in 2018. Today, due to a snafu with the track layout, eastbound passengers must switch trains at Pittsburg to reach Antioch, adding 20-30 minutes to their ride.

This BART extension was meant to bridge gaps connecting the city to the wider Bay region. However, it is located near Hillcrest Avenue—deep in the newer part of town—which puts modern amenities and transit access far from the historic northern section.

This isolation exacerbates the sense of neglect for those in the older 94509 Antioch district.

These transit investment choices help explain why Antioch is so divided. The city needs more equitable public transit services, especially BART.

City Budget and Social Challenges

In 2026, Antioch faces a myriad of structural and social challenges due to a severe budget crisis, a depleted police force, and state-mandated housing pressures.

Budget Shortfall

The city’s approved 2025-2026 budget includes a $12.5 million deficit.  Only $5 million of that was covered by the budget stabilization reserve. Due to economic uncertainty, growth in Antioch’s key revenue streams—sales tax and cannabis tax—has declined.

Public Safety & Police Staffing

Public Safety and Police Staffing: The Antioch Police Department  is facing its worst staffing shortage in decades. This follows years of scandal and federal indictments over racism in the force. Labor disputes are ongoing, and officers and dispatchers have been working without a contract since 2025.

Housing and State Mandates

Antioch is a focal point for California’s housing crisis. The City Council has expressed frustration over state laws (such as SB 330) that require approval of massive housing projects—even those linked to controversial developers under threat of litigation.

Approvals for hundreds of townhomes also received community backlash for failing to include enough low-income units. Critics argue that the developments prioritize moderate-income residents over the city’s most vulnerable.

Antioch Faces Growing Climate Challenges

Antioch faces critical climate challenges, with hotter, drier summers and more dangerous heat waves.

The area also faces significant wildfire threats and water instability due to drought and rising salinity in the Delta. Because salt is leaching into the water supply, the city has converted its existing water treatment plant to a desalination plant. (Source: Kneedeep Times)

Many Antioch buildings are at risk of wildfire. Rising temperatures, more air pollution, and flooding from intense winter storms are also affecting residents. The city is projected to experience more extreme heat days, worsening its already poor air quality. 

That’s why Antioch needs climate action now!

East County Healthy Homes Initiative to Help Antioch

East Contra Costa Healthy Homes project—Cleaner Air, good jobs, healthy housing Antioch (94509 & 94531) Climate Action & Advocacy - 350 Contra Costa Action Antioch (94509 & 94531) Climate Action & Advocacy - 350 Contra Costa Action

The East Contra Costa Healthy Homes Project is a new community effort to improve housing, public health, and local job opportunities in Antioch and Pittsburg.

350 Contra Costa, in collaboration with other nonprofits, is leading the way to an equitable transition from natural gas to clean electric energy. The non-profit collaborative is funded by California Jobs First through the Bay Area Jobs First Collaborative Program.

It plans a large-scale home electrification and retrofit initiative to transition income-qualified homeowners in Antioch and Pittsburg to clean electric heat pumps. 

We’re working with local organizations to design a program that:

  • Makes homes safer and healthier with modern electric appliances, improved ventilation, and better insulation.
  • Creates good local jobs in clean energy and construction.
  • Helps residents stay cool during heat waves and cuts pollution from old gas appliances.
  • Ensures that the communities most affected by poor air and housing conditions benefit first.

Oil Drilling Active Despite Antioch Drilling Ban

In January 2022, the Antioch City Council became the first in East Contra Costa County to pass a ban on all future oil and gas drilling, production, and exploratory operations. In 2024, Mayor Lamar Hernandez-Thorpe signed a pledge to further commit the city to a fossil-free future.

These actions reinforced the ban on new fossil fuel infrastructure. Drilling within the Antioch city limits is largely prohibited.

A specific legacy operation run by Sunset Exploration Inc., however, still exists near the city border. The drilling takes place on open land along Deer Valley Road, between Balfour Road and Kaiser Permanente Antioch Medical Center, near the Dozier Libby Medical High School in Antioch.



While we applaud Antioch’s drilling ban, its protections are diluted because Contra Costa County allows drilling on nearby unincorporated land.

The proximity of the Sunset Exploration site to a school and hospital puts Antioch residents at risk. Toxic air and water pollution from drilling can easily reach hospital patients, visitors, and nearby high school students.

That’s why we need a full countywide ban on oil and gas drilling. Read more and sign the Sunflower Alliance petition for a Contra Costa County ban on oil and gas drilling.

Antioch first adopted its Climate Action and Resilience Plan (CARP) in 2011. In 2020 and again in 2024, the City Council updated the plan. The plan aims to cut greenhouse gas emissions by 25 percent from 2005 levels, boost energy efficiency, and prepare for climate hazards such as wildfires, drought, and extreme heat.

Curiously, the city’s website no longer includes a link to the CARP. The status of the CARP’s implementation is uncertain at this time, as the city undergoes a reorganization.

The plan, as adopted on November 26, 2024, can be found in the agenda packet for that meeting. To access it search the document for ‘CARP,” which should take you to the first page of the staff report for Item J in the Consent Calendar. From there, scroll down to “Exhibit A” to view the CARP.
