The Subdivision Process

While every City or County may have its own unique process of subdividing property, most follow a similar general format. I have tried to layout how a typical plot of property might make its way from raw land to finished residential lots.

From Wikipedia
Subdivision is the act of dividing land into pieces that are easier to sell or otherwise develop, usually via a plat. The former single piece as a whole is then known as a subdivision in the United States. If it is used for housing it is typically known as a housing subdivision or housing development, although some developers tend to call these areas communities.
Subdivisions may also be for the purpose of commercial or industrial development, and the results vary from retail malls with independently owned out parcels to industrial parks.
