When the sea levels begin to really rise 50 or more years from now, it looks like the best places to be “inland” for the Houston area are the outer north, north-west, and western parts. That means Katy, Woodlands, Tomball, and Cypress. They’re also set up in convenient proximity to the other big three Texas cities of Dallas, Austin, and San Antonio.
Who knows though. It’s also possible that such a rise in sea-levels could bring forth unanticipated factors that make one or more of the areas I mentioned a lot harder to live in.
They make an exception for Houston though
> They will likely see even more people moving inland because, with the exception of Houston, of their distance from the coasts, as well as their ability to offer housing, jobs and infrastructure, all of which the study took into account when factoring in forced migration patterns.
