World Gen Structure Generating many blocks underground

This happens to me pretty frequently and it often makes me want to give up the world entirely because it looks really hideous. Unless there's a command to get rid of structures completely (that were generated automatically) and restore the vanilla terrain?

In almost every case, it tends to happen near/in water, structures will generate under the water level and cut off the terrain, and it's always a massive building or giant town.
