I would agree - it looks like they are building cribbing to move the truck over that charged hose. This looks like exactly the sort of thing that CERT volunteers might be involved in. We were fiddling with the cribbing just last week, with more scheduled for this Saturday.

This would seem to be the sort of disaster in which professional forces might be momentarily a bit short handed and would benefit from civilian volunteerism, especially if they had some CERT training.
