How can I participate?

The City Council will be holding public hearings to receive resident input on where district lines should be drawn. There will also be community outreach in the form of workshops being held in different locations around the City. Share your specific thoughts, draw a map, attend an upcoming public hearing or workshop to get involved! We want to hear your stories - tell us what your communities of interest are and give your opinions on draft maps.

Below you can view a calendar of public hearings at which you can give input about the process or a specific map.


The Districting Process

Local governments use data from the Census to draw district lines to reflect the changing local population demographics. State law requires cities and counties to engage communities in the districting process by holding public hearings and doing public outreach, including to underrepresented and non-English-speaking communities.

Why is this important?

The City of Ontario is asking for your help as we undertake the City’s first ever districting process. We want your input in planning, drawing, and dividing our new City Council districts. With your help, the finalized maps we create will define the City of Ontario council district borders and will impact how you elect your Council Members in the future.

Our primary goal when developing election districts is to draw lines that respect neighborhoods, history, and geographical elements. In order to achieve this goal, we need your input: What do you consider the boundaries of your neighborhood?

What is districting?

It is the regular process of determining the lines of voting districts in accordance with population shifts. In California, public agencies and other organizations must divide the lines of their districts according to the results of the Census, so that each district is substantially equal in population. This ensures that each elected official represents about the same number of constituents. All district lines must be reviewed to meet strict requirements for population equality, voting rights protections, and in accordance with the California FAIR MAPS Act.

Why is it important?

Districting determines which neighborhoods and communities are grouped together into a district for purposes of electing Council Members. The City Council will seek input in selecting the City of Ontario’s first district map for electing Council Members. You have an opportunity to share with the City Council how you think district boundaries should be drawn to best represent your community during the public hearings and/or by submitting comments to districts@ontarioca.gov.

What criteria will be used to determine district lines?

  1. Federal Laws
    • Equal Population (based on total population of residents as determined by the most recent Federal decennial Census and adjusted by the State to reassign incarcerated persons to the last known place of residence)
    • Federal Voting Rights Act
    • No Racial Gerrymandering
  2. California Criteria for Cities (to the extent practicable and in the following order of priority)
    • Geographically contiguous (areas that meet only at the points of adjoining corners are not contiguous. Areas that are separated by water and not connected by a bridge, tunnel, or ferry service are not contiguous.
    • Undivided neighborhoods and “communities of interest” (Socio-economic geographic areas that should be kept together for purposes of its effective and fair representation)
    • Easily identifiable boundaries
    • Compact (Do not bypass one group of people to get to a more distant group of people)
    • Prohibited: “Shall not favor or discriminate against a political party.”
  3. Other Traditional Redistricting Principles
    • Minimize voters shifted to different election years
    • Respect voters’ choices / continuity in office
    • Future population growth

What are Communities of Interest?

A community of interest is a “contiguous population that shares common social and economic interests that should be included within a single district for purposes of its effective and fair representation.” They are the overlapping sets of neighborhoods, networks, and groups that share interests, views, cultures, histories, languages, and values and whose boundaries can be identified on a map. The following elements help define communities of interest:

  • shared interests in schools, housing, community safety, transit, health conditions, land use, environmental conditions, and/or other issues;
  • common social and civic networks, including churches, mosques, temples, homeowner associations, and community centers, and shared use of community spaces, like parks and shopping centers;
  • racial and ethnic compositions, cultural identities, and households that predominantly speak a language other than English;
  • similar socio-economic status, including but not limited to income, home-ownership, and education levels;
  • shared political boundary lines from other jurisdictions, such as school districts, community college districts, and water districts

How will residents be notified about the districting process?

The City Council will notify the public about redistricting hearings and workshops, post maps online before adoption, and maintain this dedicated web page for all relevant information about the redistricting process.

Public hearing notices will be published in the Inland Valley Daily Bulletin. We will also make a good faith effort to notify community groups of various kinds and residents about the redistricting process through our social media channels. Our public hearings and workshops will be provided in applicable languages if residents submit a request in advance to districts@ontarioca.gov.

Common acronyms demographic categories:

  • NH: Non-Hispanic
  • NL – Non-Latino
  • AIAN – American Indian Alaskan Native
  • VAP: Voting age population
  • CVAP: Citizen Voting Age Population
  • CVRA: California Voting Rights Act
  • FAIR MAPS Act: Fair and Inclusive Redistricting for Municipalities and Political Subdivisions
  • BBK – Best Best & Krieger

Do I have to submit a completed map?

No, you do not need to submit a completed map. You may draw boundaries for only your neighborhood or only a portion of the city. It is helpful if you submit written commentary with your map describing why the neighborhood/area should be kept together in a single district.

Can I submit multiple maps?

Yes, you may submit as many maps as you like – there is no limit. However, we suggest you submit only your top 2-3 preferred maps to assist the City Council in focusing on the map that best represents your community.

What happens to the drafted maps?

Once submitted, maps are considered public records. After you submit your map, the demographic consultants will generate the population and other demographic details for your proposed map. Maps can be viewed on the Draft Maps page or on the Interactive Review Map.
