As I have posted extensively building massive urban complexes upon massive secure concrete hulled barges is plausible for providing human residency on the ocean. Bluntly put, the bigger the safer. My initial considerations viewed the Salish SEA as ideal along with the northern Adriatic. both these are seriously attractive as housing destinations. Do understand that these are housing builds providing the actual capital. Road, Rail, massive factory space and massive greenhouse space are all secondary to the primary build. Those are the super safe and best possible economic models. Many others exist of course even with geographic protection, but often without adjacent real estate demand. Initially those economic issues will matter most. In Vancouver's case, it becomes plausible to build out a ten million population on the Salish sea and also connect properly to Vancouver Island. Again, you have to imagine building a potential kilometer by kilometer floating barge that once
