State Land Use Planning State Land Use Planning implemented the Statewide GIS system in Delaware known as DEGIS (Delaware GIS).  These Suitability Analyses were used to determine  “Growth Areas”, also called “Investment Areas“.  The final adopted analysis identified areas throughout the state where the state wants to encourage and stimulate development based on land use, infrastructure, etc.  DEGIS Incentives are offered to encourage development in these areas.  This Development Analysis goes hand in hand with the Preservation Analysis to produce an overall State Plan for the Controlled, Orderly and Logical Growth and Preservation in Delaware.
