What is the value of the riprap apron at a culvert inlet in a native wash, and what are guidelines on how far out to extend the inlet apron upstream?
Just had a plan reviewer that wanted me to include riprap apron in front of culvert inlets, and am trying to decide how big the apron should be, which would probable be easier if I had a better feel for their value on the upstream side.
