Most large developments with multiple lots are set up as subdivisions. To create a subdivision, a record plat must be recorded with St. Charles County through the City of St. Charles. There are several documents and applications that are required to create a record plat. They include:

• Preliminary Plat Preapplication Procedures
• Preliminary Plat Application
• Improvement Plan Application
• Record Plat Application

Each of these documents contain a helpful checklist. These documents are kept in our Forms Library, which can be accessed by visiting the home page.
