Cul-de-sac design plan

this is my first time do the Cul-de-sac design. I know I should show the Cul-de-sac center line proposed profile on Plan sheet, but Not sure if I need show the proposed Pavement Edge profile on plan sheet. if not shown in plan sheet, using the cross section to control the pavement edge elevation?
appreciate any inputs,

RE: Cul-de-sac design plan

If the centerline grade is steep enough, then you can probably get away with projecting out your standard cross-slope and still get drainage around the gutter line of the culdesac bulb. But that's rarely the case, and we often have to profile the curb/gutter line to ensure that you have adequate slope all the way around the bulb to get drainage out to where you want to collect it. As far as plan labels, you don't have to show the full gutter/curb profile, but at least label the PC, PT, Mid-points, etc so it can be staked and built properly.
