"There may be laws in place to counteract. " In response to Reply #2
Mayor Bob Lanier of Houston used such a law to annex the community of Kingswood into Houston.
Lawmakers in the early 60s had the foresight to see white flight before it happened. I don't blame mayor Lanier at all. The city gave corporations giant tax breaks to locate in Houston and the employees of these businesses rewarded Houston by moving out of city limits to avoid taxes. Houston annexed Kingswood.
