In my opinion, post Apocalyptic builds are just plain silly. The sea dries up? What? Zombie Apocalypse? Alien invasion? These ideas are just preposterous. The sea is so incredibly huge that a significant amount of water would have to be drained in order for their to be a slight drop in sea level. A zombie apocalypse is just plain impossible. As far as intelligent life, the only way it could reach earth is through the fifth dimension of hyperspace. The chances of an alien invasion are practically impossible.
Enough of that, on to the build
This is the type of apocalypse that is most probable, losing power. Almost everyone has experienced a power shortage sometime or another.
