In Orange County, your supervisor district is part of the local map

Orange County has five supervisorial districts, and each one elects a county supervisor. Your district matters when the issue belongs to the county. That may be a Board hearing, county policy, or a county service.

Use the Board’s Find Your District link and search the full address. Do not rely only on the city name. Parts of some cities sit in more than one district. The districts also include county land outside cities.

Two maps are at work here. The district map tells you who speaks for the address at the county level. It does not replace city government. It also does not tell you which permit office runs a project. For a city permit or service, start with the city. For a county matter, keep the district number handy. If you do not know whether the address is inside a city, check that line before you call.
