Haha I apologize for the duplicate comments, I couldn't figure out how to delete them. 

I just realized I didn't add it in. I was talking about the basin to the southwest of this intersection. It is really just a giant depressed inlet for the large storm drain that crosses Avenue H to the west of the intersection, but I think it should be labeled as a basin since it also allows for detention and desilting. 

I changed a few of the streams to culverts under the street, and added a new culvert on the south side of the basin to the southwest, and added an inlet and an outlet to that pipe; the stream that was already there still exists, since the pipe isn't big enough to collect all of it. I also added an inlet and an outlet to the bridge that crosses avenue H west of the intersection, and added an additional area layer for it since it has a huge apron.

I am realizing now I might not have published it, so I will do that so it can be reviewed.
