Award winning reporter Jason Van Derbeken in his latest article reporting on the Berkeley deck tragedy reports-
"Attorneys representing the family of a Berkeley balcony collapse victim have contacted prosecutors to alert them to witness accounts that the deck had a “seemingly unusual slope” before it gave way during a party."
Decks are required to have a minimum of 2 percent slope to them do water will drain of and away from the building. If the deck pitches much more than 3 or 4 percent, anyone standing on the deck will feel like they are being pitched forward and will have to make adjustments to their posture, but will remain uncomfortable. Imagine walking down a steep hill; it's not comfortable and you make adjustments in your gait and posture.
The same feeling will occur on a deck with a high degree of slope on it. To me this indicates a warning sign of problems in the deck. It wouldn't necessarily indicate that the deck was ready to fall, but I would, if I was inspecting a balcony with that condition, raise a red flag.
