To answer your questions,
#1. I will work with the DoI to find the easiest way to optimize our infrastructure, however my decisions will be more strongly influenced by other factors, i.e. resources, luxeries, and terrain.
#2. I don't see why not. I would, through a culmination of each possible sites effects/costs, find the best possible choice and rank them as such. This also describes my decision process (which will also include a lot of citizen feedback).
