Send in the troops and have the Core of Engineers actually build out infrastructure and cities to bring them up to modern code in a maintainable way. Also pull in some locals for education in how that stuff is done in the process and try to do knowledge transfer of "This is how you build civilization that does not get flattened by a hurricane."
Given the political history, I doubt that would go well. Is there a foreign military power with a similar skill set that could do this task?
