JUSTIFICATION:
The concrete channel invert slab is required to prevent scour that would most likely occur around new bridge piers,
that would undermine the bridge footings and could also impact the channel slope paving. CVWD would not issue an
encroachment permit without adding the invert slab. Similar scour occurred at the Monterey Bridge that required
paving of the invert after that bridge was completed.
