Drainage Design
(OP)
I am currently working on an urban roadway widening project, which is about 3 miles long. I encountered a problem when designing drainage. The site is flat and constructing series of underground culverts is not feasible. Therefore, I came up with two alternatives:
• Raise the existing pavement and construct an earthen ditch along one side of the roadway
• Construct earth berm
However, these two designs will require additional ROW. Can anyone suggest a drainage system with less impact? Thanks for the help.

RE: Drainage Design
This is a widening of an EXISTING road ? How is this roadway and right of way drained now ? If there are existing culverts, why can't they be extended ? If there are no culverts, only ditches along the alignment, why can't they be relocated along, and parallel to, the widened section ?
Good luck
