Surface not triangulating correctly

[codee]

I have a set of feature lines I am using to make a surface. When I add them to the surface 2/3 of the triangles on the curves are not actually on the curve. it is a consistent pattern of one on the curve and then two off the curve. It does not matter if I set the mid-ordinate distance to .1 or .05 I get the same result. It is making my offset profiles have different elevations despite the road being constructed symmetrically.  Any help would be appreciated.

DWG attached.

The area circled on the north side needs an additional FL to stop it from bulling to your ditch or pond so abruptly, the ordinate distance on those FL's define the ditch or pond seem a like there not small enough, Adding a FL for how you want it to look is a quick way of fixing the issue.

What I had circled was the flow line. The ponds are not the issue. I think the problem is that my supplemental factor was creating triangulation as shorter distance on curves than my mid-ordinate distance was creating.

[EDIT] That was the issue. Upon increasing the distance of my supplemental factor all the triangles now end up on the line but they only appear where the Mid-Ordinate distance dictates and no more than that.
