Participate in democracy during BART’s remaining redistricting meetings

Proposed BART Districts 2022 Plan A

For redrawing BART director districts; next meeting today at 9:00 a.m.

RELEASE DATE: 01/14/2022

Have a direct say in democracy by participating in BART’s redistricting meetings. The next virtual meeting is scheduled for January 15, at 9 am, followed by two 6pm meetings on January 22nd and February 2nd.

BART election districts are redrawn every 10 years following the U.S. Census. The primary purpose of redistricting is to ensure population equality among districts.  This process is guided by traditional redistricting principles as well as the U.S. Constitution, the California Constitution, the federal Voting Rights Act and the BART District Act.

Districts must be contiguous and should also be compact, minimize splitting cities, respect communities of interest and follow natural and man-made boundaries.

Key Points to Consider in Redistricting

Traditional Redistricting Principles

Since decennial redistricting began in the late 1960s, traditional criteria and principles have developed. While the equal population of election districts is the overriding principle there are accompanying goals. In varying degrees, the criteria are compactness, continuity, respect for communities of interest, preserving political subdivisions, and the core of previous districts. All are not of equal weight, and all are subordinate to an equal population. Care must be taken not to dilute the voting strength of minorities.


Compactness refers to a districts’ geographic shape and how its interior is dispersed within its boundaries. A circle is a perfectly compact shape. In redistricting, the notion of compactness is difficult to evaluate because one begins with irregularly shaped borders and the political subdivisions may be irregular in shape. Geometric measures of compactness are often misleading because geographic features and relationships are more complex than simple geometry. The principle of compactness should be considered functionally and must compete with other criteria.


Continuity requires that all parts of a district be connected. Districts can be drawn that are contiguous by way of water or a bridge. While crossing water is allowed it should be minimized as it makes it more difficult to respect communities of interest.

Preserving Political Subdivisions

An attempt should be made to minimize splitting cities and well-defined neighborhoods.

Respect for Communities of Interest

Communities of interest are subjective and difficult to define. A community of interest has some common thread of shared interest. Those communities can be based on such diverse elements as geography, language, socio-economic-cultural interests, even transportation corridors. Race may be considered, but it may not be the sole reason for drawing a district in a particular manner.

Preserving the Core of Prior Districts

Preserving the core of a previous district is thought to be the least disruptive to the voters in each area. One, of course, would not seek to maintain a previous district that was legally objectionable.

New districts should be drawn deliberatively and with common sense. Adherence to traditional redistricting principles and the federal Voting Rights Act will ensure fair and reasonable districts.

Mapping Tools for Public Engagement

BART has rolled out mapping tools to enable public input for redistricting.

BART interactive mapping tool for redistricting: This tool gives residents the ability to create and share a Community of Interest and/or draft Board of Director districts. Map submissions will appear in the gallery on the main landing page, enabling residents to view public input for redistricting.

BART Districts and Demographic Data: This web mapping tool is for visualizing BART districts and demographic data.

In addition to the interactive mapping tool, BART is providing a Community Input Map to allow residents to identify and provide supplemental information regarding their Community of Interest. This feature can be used on a mobile device and is offered in English and Spanish (Español), providing residents with an app that can be used to submit community information in their language of choice.
