What political process allows you to demolish all those houses without an impossible political deadlock about compensation land rights etc?
Eminent domain. See, for example, Kelo vs New London, which held that the government can even take property and give it to another private party if they feel like it.
Dikes/etc, or simply landfill to raise ground level can handle the valuable high density areas. This was already done in Seattle 100 years ago, for example [1].
Migration is also a pretty easy solution to the less densely populated areas. NYC's population declined 10% between 1970 and 1980. Newark NJ's population went down 40% between 1930 and 2010. You think we can't depopulate Long Beach house by house over the next 300 years?
Please recall that 300 years ago, the United States and India were part of the British Empire, the cowpox vaccine was new technology, and the empire of Comancheria [2] was just getting started.
[2] Comancheria was an empire spanning Texas, Kansas and New Mexico, and was the major power in that part of the world until the 1870's. Rose and fell in less than 300 years.
