That's a very good question. In the event the water gets up to that
elevation, it would be a good idea to have a concrete cut -off on the
uphill side of the concrete. The cut -off would serve to: 1.) prevent
any water from being directed underneath the existing concrete slope
protection via the "porous" gabions and 2.) facilitate direct and
intimate contact between the gabion wall and uphill edge of the concrete
slope protection. All things considered, I think it would be simplest
(and sufficient for the function) if the cut -off were formed by widening
the concrete beam /pier cap within the Row 1 gabions out to the face of
the gabions (i.e., poured in direct contact with the uphill edge of the
concrete slope protection). The top of the cut -off would be in plane
with the existing slope protection (Elev. 500.0 approx.) and the bottom
would correspond to the base of the Row 1 gabions (Elev. 499.5).
Because the cut -off will be placed monolithic with the concrete beam, a
separate bid item will not be required. The concrete beam quantity will
only have to be increased by 1 CY (20.5'x 1' x V= 0.76 CY). We will
go ahead and add this detail to the final drawings and adjust the
quantity estimate accordingly.
Thank you for your comment/question.

Joel:
There is a 6" x 18" toewall around all sides of the concrete slope
protection. The portion of the slope protection to be removed for
construction of the bottom gabions includes this toewall. Will another
toewall need to be poured for the uphill side of the slope protection?
