This area is particularly larger than its original counterpart, though it retains its "L" shape. It's also possible to see a path next to the entrance to the Refuse collection point, in the original, the room stops there.

Resident Evil: The Darkside Chronicles
This area appears at the end of the Memory of a Lost City 5 chapter, it's where the Giant Alligator boss fight takes place. All the files that can be collected in the chapter are inside this room, they are: Sewer Manager's Diary 2, HUNK and Sewer Manager's Fax and are collected the same way, once the Alligator stops playing dead and turns around the corner, he will destroy all wooden boxes, the 3 files are inside these boxes, a Herb is also dropped from one of the boxes.
Just like most boss fights in the game, the Giant Alligator is heavily scripted and can't be killed early, even if the player uses a Rocket Launcher or Linear Launcher. However, it's possible to kill this boss without using the canisters.
