A more thorough explanation:

Interim zoning is a temporary emergency zoning that is put in place while revisions to existing ordinances or the development of a final zoning plan is being made. It is also known as stopgap zoning.

For example, if a city is experiencing a sudden surge in population and there is a need to control the use of land until a permanent zoning plan is developed, interim zoning can be put in place. This will help to prevent any haphazard development that may occur in the meantime.

Interim zoning is a useful tool for cities to manage their growth and development in a controlled manner.
