Helipad Numbers

About a year ago I had a conversation with Eric Richardson where we pondered the numbers on the landing pads on the buildings in downtown LA. I knew they couldn’t be pad identifiers because they repeated themselves. I guessed the had something to do with the capacity of the pads, and as it turns out that is just what they are for. LA City Nerd did the actual research and found out they represent the pounds in thousands that the pad can hold in case of an emergency landing.
