Post-Flood America

This is a replacement version for a previous Deviation of the same title; a deviation that I feel did not fit the scenario I made it for and have thus revised it for this map.

After decades of drought, floods, extreme winters, food shortages, and super-hurricanes; in the 2040s climate manipulation had finally brought sea levels back to Pre-Flood levels in most areas, and countries began to reoccupy lost territory.

The United States, like many nations during the period of the Flood, expanded dramatically prior to this point due to a number of military conflicts on its borders aimed at protecting their own climate refugees and combating the mass criminal revolutionary, and paramilitary sects that sought to take advantage of the weakened state of neighboring governments. Despite this territorial aquisition population centers shrunk as less and less land was able to support a large human population. Lousiana, Deleware and Florida were completely lost to the sea, while in the interior whole cities would be abandoned as water became too scarce.

With the flood waters receded, America found itself, like many countries, repopulating areas that had not seen civilization in close to three decades. Many of these new territories were simply reorganized into states that hadn't existed in years, though their borders were radically different due to the effects of being underwater for thirty years; while others were simply given new territory as was the case with Dixie (a state that formed out of the surge in refugee populations in Northern Mississippi, Alabama, and Georgia.)

As in the case of Dixie, State lines had changed radically over the last several decades, even before the flood waters drained. As populations moved inland, the great Megalopolises of the Great Lakes and the western States grew exponentially, merging into expansive tendrils of singular metroplexes, whose power and authority supplanted those of the old states. As such a number of states began consolidating territory around these megaregions, while some states didn't change at all due to low population density. After the flood waters receded the US Congress agreed to consolidate the most underpopulated regions of the country into new states that better fit the geography and demographics of the area. Alaska and Canada were the most radical cases, as their populations had bean sprouted then drained following the stabilization of the climate.

On the East-Coast, the greater Bos-Wash metroplex had been fractured by the flood, and split up into several smaller metroplexes; mainly the greater DC area, New York, and the New England Metroplex.

Prior to the drainage, these pseudo city-states, had largely abandoned local and state government in favor of online legislatures that better allowed singular communities to manage themselves, while allowing the whole of the state to come together on single pieces of legislation. This would later be applied to the Commonwealth system as well.

During the colonization period, the urban sprawl that once filled in these great megaregions was slowly abandoned, leaving the much more developed interior of the cities the only parts that were still populated. With this in mind many nations began to rewild these now empty suburbs, and declare vast new public parklands and protected reserves.
