Pad and footing are all one. 2 course of cinderblock on top. In 2010 we had water above the cinderblock by a few inches.
My guess and I need to get an engineer out here to prove it is that when the new development went in and they raised the property over there, the berm acts as a dam so to speak and hold the water where before when it was a farm it probably just all spread out so was never a problem.
Heavy rains started last night and supposed to end later today. As of this morning here is what it looks like. Still dry inside garage though.
