The other only place for looting located in the bottom part of the map that is worth mentioning is Flush Factory.
Pay special attention to the southern building of the factory, where you will see a large platform -- there is always a chest spawning on top of it. But don't neglect the periphery of the factory either, so go and check for the loot outside. You might find something that you really need.
