headwall footing depth
headwall footing depth
(OP)
I am designing a concrete headwall for drainage pipe and want to know how far below the riverbed should the footing be? Frost depth is 4'. I would normally think the footing should be at frost depth, but I've seen headwalls that seem to bear right at the surface. Isn't scour also a concern?
