The new Supervisorial map takes three different approaches to OC’s three most populous cities, all of which have more than 300,000 residents. The county’s most populous city, Anaheim, finds itself the only OC city to be split in three: most of Central Anaheim is in the 2nd, Anaheim Hills is in the 3rd, and oddly, the 4th has a combination of West Anaheim (west of the 5), far western and northern portions of central Anaheim, combined with most of East Anaheim east of the 57 but west of Anaheim Hills. A lot of people spent time trying to divine Anaheim roads from the map to determine which parts of Anaheim were in the 2nd versus the 4th. (Previously, the Anaheim split had simply been Anaheim Hills in the 3rd and the rest of Anaheim in the 4th.)
The second biggest city, Santa Ana, was kept wholly in the 2nd District. (Previously, Santa Ana had also been whole, but in the 1st District.)
The third biggest city, Irvine, now has a 70%/30% split between the 3rd and 5th Districts, with areas west of the 405 in the 5th, along with the northern part of the El Toro Y containing the Irvine Spectrum (west of the 5 and south of the 133). (This had previously been a 90%/10% split between those two districts.)
Where Cities Ended Up
The 1st District (2024) hangs on to Little Saigon, but gives up Santa Ana and picks up the former Second District areas of Huntington Beach, La Palma, Cypress, Los Alamitos, Rossmoor, and Seal Beach. (Arguably, this is actually the old 2nd District giving up Costa Mesa and Newport Beach while picking up Little Saigon and the latter’s district number.)
The new 2nd District (2022) has no geographic overlap with the old 2nd District. The new 2nd now consists of Santa Ana and far eastern Garden Grove (from the old 1st), most of central Anaheim (from the old 4th), and the majorities of Orange and Tustin with a small portion of North Tustin (from the old 3rd).
The 5th District (2022) picks up Costa Mesa and Newport Beach (from the old 2nd), increases its share of Irvine from 10% to 30% (picking it up from the 3rd) while giving up Lake Forest, Mission Viejo, and Rancho Santa Margarita (to the new 3rd). It hangs on to Aliso Viejo, Coto de Caza, Dana Point, Ladera Ranch, Laguna Beach, Laguna Hills, Laguna Niguel, Laguna Woods, Las Flores, Rancho Mission Viejo, San Clemente, and San Juan Capistrano.
The 3rd District (2024) gave up the majorities of Orange and Tustin and a portion of North Tustin (to the new 2nd District) while picking up Lake Forest, Mission Viejo, and Rancho Santa Margarita (giving it up to the 5th). It reduced its share of Irvine from 90% to 70% (giving it up to the 5th). It retains Anaheim Hills, Villa Park, Yorba Linda, the canyons, portions of East Orange, most of unincorporated North Tustin, and eastern portions of the City of Tustin.
The 4th District (2022) had the least change: it simply picked up Stanton and the remainder of Buena Park from the old 2nd District while giving most of central Anaheim to the new 2nd
District. It retains Brea, Buena Park, Fullerton, La Habra, Placentia, and the majority of Anaheim.
