or perhaps for additional support for the driver that always seems to miss the opening ? kindof like a built in bollard ? :-)

I'm guessing (I admit it); but reasoning, in this case, from the "concrete" to the "abstract", perhaps it's to add additional weight to counteract uplift.  I know it can be a problem frequently that there is not
sufficient mass (or weight) in a footing or foundation to take the uplift of a fully rated holdown.

But then, how close to the beach did you say it was?  Maybe it's the anchor?
