Cleaning up contours to elevate edge of pavement from can be a pain and tedious. 



Here is a trick I found. I think it speeds up contour cleanup along edges of pavement, especially for site style projects. 




  1. Elevate edge of pavement
    • Could be as simple as putting it at elevation 1. This is just so that the create side slope function will work  
  2. Use create side slope
    • Create two lines far enough on either side of the edge of pavement to trim the bad contour data
  3. Join the side slope lines to create a closed polyline
  4. Join the contours to be trimmed
  5. Use the clip command
    • Make sure to use the "Remove lines inside bounding lines" method
    • Select the lines to line and the bounding line
  6. Turn off edit layers
  7. Use the trim/extend command and extend the trim turns to the the edge of pavement
  8. Elevate edge of pavement using the elevate lines commands


Process in action:




I think it works pretty well. They one thing that would make this easier is a polyline select function.



If anyone has any other tricks, feel free to share.
