The Map Checking and Annexations Unit is the repository for various city and district maps within Orange County and is responsible for:
Checking the legal description and map for proposed annexations (city/district gains previously unclaimed land..i.e. unincorporated territory [in a city situation] or land not currently within a district).
- Reorganizations (swap of land between 2 similar cities/districts)
- Incorporations (when a new city is established)
- Formations (when a new district is created)
- De-annexations (when a city/district detaches land that is now being given to another city/district).
