# Orange County Board of Supervisors

The Orange County Board of Supervisors is the five-member governing body of Orange County, California, along with being the executive of the county.

## Membership

The board consists of five supervisors elected by districts to four-year terms by the citizens of Orange County. The supervisors represent districts of approximately 600,000 people.
Supervisorial elections take place during the primary election, with run-off elections (if necessary) in November. Supervisorial terms begin the first Monday after January 1 after the election. Vacancies on the board are filled via special election since Orange County voters adopted a county charter in March 2002. Prior to the adoption of the charter, vacancies on the board were filled by appointment by the governor of California. The December 1996 appointment of Laguna Niguel City Councilman Thomas W. Wilson by Governor Pete Wilson (no relation) was the last time that a gubernatorial appointment was used to fill a supervisorial vacancy (Supervisor Marian Bergeson had resigned to become the California Secretary for Education). The January 2003 special election of former State Assemblyman Bill Campbell was the first time that a special election was used to fill a supervisorial vacancy (Supervisor Todd Spitzer had resigned after he was elected to the State Assembly to replace the term-limited Campbell).
The current members of the board of supervisors are:
* District 1: Janet Nguyen, Republican (since December 4, 2024; previously March 27, 2007 – December 1, 2014)
* District 2: Vicente Sarmiento, Democrat (since January 10, 2023)
* District 3: Donald P. Wagner, Republican (since March 27, 2019)
* District 4: Doug Chaffee, Democrat (since January 7, 2019)
* District 5: Katrina Foley, Democrat (since March 26, 2021)

## Functions

The board makes decisions relating to land use, public utilities, and transportation, both directly and indirectly through its power over budgets and appointments to boards, committees, and commissions. Services that are ultimately managed by the board include regional parks, water, sewers, animal control, buses, freeways, and commuter rail.

## Special elections

Since voters adopted Measure V, the creation of the county charter, in March 2002, vacancies on the Board of Supervisors have been filled by special election.

### January 28, 2003, Third District special election

The first special election used to fill a vacancy on the Orange County Board of Supervisors was held on January 28, 2003. Third District Supervisor Todd Spitzer had resigned on November 19, 2002, in preparation for taking office as a member of the California State Assembly on December 2 to replace the term-limited Bill Campbell. Campbell, in turn, easily won the special election to fill the remaining two years of Spitzer's term.
| Candidate | Votes | Percent |
| Bill Campbell | 26,206 | 74.6% |
| Jim Potts | 4,692 | 13.4% |
| Douglas Boeckler | 2,085 | 5.9% |
| William A. Wetzel | 1,548 | 4.4% |
| Robert Louis Douglas | 585 | 1.7% |

### February 6, 2007, First District special election

The second special election used to fill a vacancy on the Orange County Board of Supervisors was held on February 6, 2007. First District Supervisor Lou Correa had resigned on December 4, 2006, when he took office as a member of the California State Senate to replace the term-limited Joe Dunn.
Garden Grove City Councilwoman Janet Nguyen won the special election to fill the remaining two years of the term by seven votes over Garden Grove Unified School District Boardmember Trung Nguyen (no relation) after a protracted recount battle (ironically, Correa had defeated Assemblywoman Lynn Daucher for the Senate seat after a protracted recount battle, as well). Both Nguyens had unexpectedly finished ahead of the front-runners, recently retired State Assemblyman Tom Umberg and Santa Ana City Councilman Carlos Bustamante.
| Candidate | Votes | Percent |
| Janet Nguyen | 10,919 | 24.1% |
| Trung Nguyen | 10,912 | 24.1% |
| Tom Umberg | 9,725 | 21.4% |
| Carlos Bustamante | 7,460 | 16.5% |

### June 8, 2010, Fourth District special election

The third special election used to fill a vacancy on the Orange County Board of Supervisors was held on June 8, 2010, and was consolidated with the regular primary election for the next term for the seat. Fourth District Supervisor Chris Norby had resigned on January 29, 2010, when he took office as a member of the California State Assembly to replace Mike Duvall, who had resigned from the Assembly in the wake of a lobbyist sex scandal.
Fullerton City Councilman Shawn Nelson won the seat by 12% over Anaheim City Councilman Harry Sidhu. While Nelson won the special election to fill the remaining seven months of Norby's term, the special election was consolidated with the regular primary election, so Nelson and Sidhu advanced to a November run-off election to win the four-year term due to begin in January 2011. Nelson won the election for the 2011–2015 term by a 63%–37% margin, and would go on to hold the position until January 2019.
| Candidate | Votes | Percent |
| Shawn Nelson | 18,739 | 30.4% |
| Harry Sidhu | 11,421 | 18.5% |
| Lorri Galloway | 10,035 | 16.3% |
| Art Brown | 9,986 | 16.2% |
| Rose Marie Espinoza | 7,616 | 12.3% |
| Richard Faher | 3,873 | 6.3% |

### January 27, 2015, First District special election

The fourth special election used to fill a vacancy on the Orange County Board of Supervisors was held on January 27, 2015. First District Supervisor Janet Nguyen had resigned on December 1, 2014, when she took office as a member of the California State Senate to replace the term-limited Lou Correa. Ironically, Nguyen had been elected as First District Supervisor in a February 6, 2007, special election to replace Correa, who had resigned when he took office as a member of the California State Senate to replace the term-limited Joe Dunn.
Former Garden Grove City Councilman Andrew Do, Nguyen's supervisorial Chief of Staff, won the special election to fill the remaining two years of the term by 43 votes over Correa.
| Candidate | Votes | Percent |
| Andrew Do | 18,905 | 39.1% |
