In my opinion there are other problems with the community mailboxes for persons with disabilities anyway. There is the question of ergonomics, the height of the top row of a community mailbox, which they might have to reach. There is the issue of inclement weather. I'm of the opinion that reducing delivery or pushing people further into using community mailboxes does reduce the standard that we have now.
