Suisun City

Suisun City is located in south-central Solano County. The city is the gateway to the expansive wetlands of Suisun Marsh, the largest contiguous estuarine-marsh remaining on the west coast of North America. With a population of about 30,000 people, the city shares resources with neighboring Fairfield to the north while maintaining authority over local matters within an engaged city government. With its waterfront and marina community, Suisun City celebrates its connection to the water and nature unlike many other places in Solano County.

On this page, you can learn more about the Environmental Impacts that face in Suisun City; the Pollution Indicators that affect local communities; City Efforts, including plans and commissions; an Environmental Directory of community organizations; and the involvement of Sustainable Solano Programs in Suisun City.

Environmental Impact

With Suisun City’s relationship to the marsh, flood- and water-related issues have the greatest impact on the city today and into the future. With rising sea levels, high tides and unprecedented rain events coupled with aging infrastructure and new development, the city is at risk of being highly impacted by flooding. The focus areas south of state Highway 12 are the most susceptible to water events, but the entire livelihood and pride of Suisun City is at risk into the future.

Additionally, due to the nature of Northern California’s climate and geology, Suisun City is highly susceptible to drought, wildfire and earthquake hazards common with much of Solano County. Each of these brings separate potential impacts to the livelihood and vitality of the city, but when taken together present unique challenges to Suisun City’s dynamic environment.

Pollution Indicators

The California Communities Environmental Health Screening Tool is used to evaluate communities based on pollution burdens and the characteristics of people living in these communities. This information helps identify California communities that are most affected by different sources of pollution. Each of the data points below represents a value for a census tract as it compares to other census tracts in California. Census tracts are small, relatively stable statistical subdivisions of a county and usually contain between 1,200 to 8,000 people, with the optimal size of 4,000.

Census Tract

This is the highlighted census tract within Suisun City with color-coded indicator dots to reflect the pollution and socioeconomic indicators.

The information has been color-coded to reflect the severity of each pollution and socioeconomic indicator:

    Focus Neighborhoods

    Zoom in and select a neighborhood on the map to get important environmental and socioeconomic information.

    These neighborhoods were selected using careful analysis of pollution burden and population characteristics indicators found in the CalEnviroScreen3.0 database. Each indicator is a measure of either environmental conditions or health and vulnerability factors.

    Learn more about the indicators in this summary document or on the CalEnviroScreen site.

    The census tracts with higher pollution burdens and population characteristics indicators were compared to the Nutrition, Education and Obesity Prevention Branch GIS Map. This database includes different demographics, including census blocks of people living under the federal poverty level.

    It was using these two databases that the final neighborhoods were picked.
