During the public hearing, the hearing body considers the application and reaches a decision to either approve, conditionally approve, or deny the application.

Any aggrieved person can appeal a decision to the Board of Supervisors. Projects located within the Coastal Zone can be appealed to (or by) the California Coastal Commission.

Step 9: Record Subdivision
