The order of generation is terrain, decorations (which is trees, flowers, grass), then things like lakes, ravines, rivers, and caves, then finally villages/structures.This is why you have floating trees near lakes, this is why you come across broken flowers/seeds in the sand or gravel along sources of water, and this is why the fences float like that. It's also why you end up with massive pilings going down to the bottom of a ravine under a building, house, or wall So it's an issue of how Minecraft works and there's probably nothing Mevans can do about it.
