Below are some images I created for a project I'm working on. They are a little rudimentary, using just Google Earth, but I think it's interesting. The image of 2005 is just a basic outline of developed areas as they existed two years ago. The image of 2025 is based off comprehensive plans adopted by the communities and current growth trends, and the image of 2040 is fairly speculative, but I believe realistic nonetheless. Metropolitan population projections are from the City of Sioux Falls
Current (2005) Conditions (Pop: 207,918)
2025 Conditions (Pop: 320,650)
2040 Potential Conditions (Pop: 406,550)
This is the first time I posted images, so hopefully it works.
