9 Ft of Water in the Basement

That's what the sign said, "Danger, weak floor, 9 feet of water in the basement, You will drown". Bungalow in the middle of an old neighbourhood. Neighbours all around, but it's on a quiet street with an easy approach, covered by trees. There is a similar house directly across the street, but there is no cover so the approach is a little more difficult. I'll leave that one for the more adventurous among you.
