Climate Vulnerabilities
Topics
Legacies of land-use discrimination, a confluence of geographic features, and a high share of residents experiencing housing and economic insecurity put North Richmond at risk of devastating impacts from climate change if no action is taken.
Inland Flooding & Sea Level Rise
North Richmond is poised to experience flooding of Wildcat Marsh by 2030 with more severe impacts to shoreline assets, coastal ecosystems, and communities with 36 inches of sea level rise, which could be a reality as early as 2050.
Sea Level Rise in North Richmond
North Richmond’s low lying geography and proximity to Wildcat Creek and the bayshore make it a bowl for collecting water and therefore extremely vulnerable to overtopping and flooding.
Acute rainfall events have offered a glimpse into the severe impacts that are to come. Sea level rise will further exacerbate flooding by first causing damage to bayside marshlands that act as the first line of defense.
Shoreline infrastructure and industry on the westside of Richmond Parkway will be impacted, followed by flooding in the residential areas of North Richmond, which is likely to occur by 2100 with 84 inches of sea level rise. These flood impacts may be further compounded by shallow groundwater conditions that could result in the flooding of inland neighborhoods long before 2100.

Vulnerable Populations
Flood impacts are not distributed or experienced equally—residents already experiencing housing insecurity, economic stresses, and health conditions are more likely to be adversely impacted by climate change.
Social Vulnerability and Sea Level Rise
North Richmond has faced decades of environmental injustice and state-sanctioned discrimination that can still be seen today through the clustering of toxic land uses, its unincorporated status, and the relative lack of infrastructure and services to serve the community.
Decades of discrimination cannot be undone overnight, and while local advocates have achieved amazing success in limiting further harm, the North Richmond community remains one of the lowest income areas in Contra Costa County.
Income and race are two of the largest social factors determining how a community experiences and is able to recover from climate events. While North Richmond’s residential communities are not forecasted to be directly impacted by flooding until the end of the century, flood impacts will cause disruptions to the community much sooner in the form of transportation interruptions and impacts to water and sewer utilities.

Infrastructure & Contaminants at Risk
North Richmond’s shoreline is home to infrastructure and uses that are at high risk of flooding—disrupting the region as a whole and posing significant risk to neighboring communities that will face contamination and severe public health impacts if harmful toxins are deployed from the flooding of industrial lands.
The West County Wastewater District, which treats and disposes of wastewater for roughly 34,000 residents and 900 businesses, operates a sewage treatment plant in North Richmond that is highly vulnerable to sea level rise impacts.
Adjacent to this facility are the Golden Bear Transfer Station (dump) and the Republic Services Landfill, which are similarly at risk of flooding and pose significant risk of chemical leakage into the area’s water systems.
West of Richmond Parkway is a clustering of industrial uses as well as a pump station on West Gertrude Avenue, which had emergency repairs in 2020 and is currently a vital piece of infrastructure responsible for pumping water out of North Richmond. This infrastructure is in dire need of repair.
Chevron’s adjacent refinery operations are chemically intensive and pose another risk to the community if toxins are exposed.
Sea Level Rise Risks Exposing Contaminants
Flooding, sea level rise, and shallow groundwater conditions, in tandem with an inadequate water and sewer infrastructure, can expose these harmful contaminants, which may leach into groundwater and pose serious public health risks.
Remediation of harmful contamination will be extremely difficult and expensive, potentially resulting in mass displacement of residents.
