United States Congressional Plan
The PRA’s United States Congressional plan for Orange County centers federal Voting Rights Act compliance and communities of interest that reflect the needs of the county’s most impacted residents. With districts drawn to population equality requirements, the plan also respects other redistricting criteria established under Proposition 11, such as contiguity, maintaining the integrity of city and county boundaries, and compactness when not conflicting with core principles. To ensure its viability as part of a statewide map, it was also coordinated and aligned with plans submitted by statewide and regional partners.

Respect for the federal Voting Rights Act. The PRA plan maintains a Latinx Section 2 district with Santa Ana, west Anaheim, and south Fullerton.
Respect for communities of interest. The PRA plan centered numerous communities of interest in the drawing of congressional lines, including race as one of many factors. AMEMSA, Asian American, housing cost-burdened, immigrant, Latinx, limited English proficient (LEP), low-income, nail salon worker, Pacific Islander, environmentally impacted, uninsured, and other populations in need were considered in identifying both communities of interest and geographic areas that were similar to and different from one another. Given their prominence in Orange County, the plan also maintained the integrity of coastal communities of interest when possible.
Respect for population equality. The PRA plan includes districts whose total populations fall within +/- 1 person of the ideal population of 760,066 persons per congressional district.
Respect for the requirement of contiguity. The PRA plan draws continuous congressional districts.
Respects the integrity of city and county boundaries. In developing the PRA plan, city and county boundaries were crossed for only three reasons: to ensure population equality, comply with the federal Voting Rights Act, and respect the integrity of communities of interest that cross city or county lines.
Respect for the requirement of compactness. The PRA plan draws compact districts where possible, understanding that federal Voting Rights Act compliance in both Orange County and surrounding areas and maintaining the integrity of communities of interest may require drawing less compact districts.
Coordinated and aligned with statewide and regional partners. Recognizing that redistricting does not occur in a vacuum, the PRA plan is generally aligned with those of statewide and regional partners, including Asian Americans Advancing Justice and the Black Census and Redistricting Hub statewide, the People’s Bloc in Los Angeles County, IE United in San Bernardino and Riverside Counties, and Alliance San Diego in San Diego County.
UNITED STATES CONGRESSIONAL DISTRICT OC1
District OC1 is a Section 2 Voting Rights Act required district for Latinx communities in Santa Ana, west Anaheim, Stanton, south Fullerton, and surrounding areas. Based on official redistricting data released from the Statewide Database at U.C. Berkeley in September, Latinx can constitute a majority of an assembly district’s citizen voting-age population in this part of Orange County. The PRA has commissioned the UCLA Voting Rights Project to conduct a racially polarized voting analysis examining the relationship between the racial composition of precincts in the district and support for candidates of choice, with outcomes to be provided to the Commission shortly. The district also unites disproportionately immigrant and low-income communities and maintains the integrity of the Little Arabia community of interest, located in west Anaheim on Brookhurst Street between Crescent Avenue and Katella Avenue.

UNITED STATES CONGRESSIONAL DISTRICT OC2
District OC2 brings together three communities of interest, Korean American communities in west Fullerton and north Buena Park, AMEMSA communities in Buena Park, La Palma, Cypress, Cerritos, and Artesia, Vietnamese American communities in west Garden Grove, Westminster, west Santa Ana, and north Fountain Valley. Outside Los Angeles County, some of the largest Korean American communities in the state reside in north Buena Park and west Fullerton. As part of their daily lives, AMEMSA communities in Orange County cross into Los Angeles County to shop in ethnic markets, dine in restaurants, worship, and access social services in Artesia and Cerritos. To the south, Vietnamese American communities in west Garden Grove, Westminster, west Santa Ana, and north Fountain Valley share common refugee experiences and the need for social services and affordable housing. Resting between federal Voting Rights Act obligations in Los Angeles County to the north and Orange County to the south, these communities of interest share experiences as immigrants and common needs such as language access.

UNITED STATES CONGRESSIONAL DISTRICT OC3
District OC3 keeps Irvine and Costa Mesa whole, drawn together with parts of Tustin and Orange, and apart from more affluent coastal communities like Newport Beach and Laguna Beach. Irvine is one of the fastest growing cities in the state. Between 2010 and 2020, Irvine added over 95,000 new residents; among cities statewide with at least 100,000 people, none grew faster over the past decade. This dramatic increase has been fueled by ongoing growth in immigrant communities. With growing numbers of Asian American, Pacific Islander, and AMEMSA residents, the city is also home to an emerging low-income population with needs similar to those of Latinx communities in Costa Mesa. Recognizing common needs related to affordable housing, language access, and other concerns, public programs providing rental assistance and workforce development target communities in both Irvine and Costa Mesa. These needs are much different than those of affluent coastal communities like Newport Beach and Laguna Beach.
