Corridor Cul-De-Sac Alignment

[RobertEVs]

I have seen several videos on Corridor Cul-De-Sac and pretty much have the gist of it. Question is the alignment of the cul de sac. Some videos have the alignment starting at the center of the cul-de-sac while others have the alignment go through the center and tie-in at the far side mid point of the ETW line. Which one is the correct method of designing?

I actually have the alignment extend beyond the sidewalk so the profileview can display the FG profile (sampled from the FG surface). I mask the portion beyond the RP.

Thanks Jeff.

"RP"? Radius point?

[MMcCall402 · Accepted solution]

Extending beyond the radius point (RP) will also allow you to show network pipes and structures in those areas in the profile views.

Hello,

I have used both methods.

In Texas, i used the alignment following the curb line.

this allowed creating low points for curb inlets.

(and that was not a problem, as ALL the utilities had their own alignments and plan/profile sheets)

I am now in Washington, and here we extend the alignment through the cul-de-suc and another 50-feet.

we do not have separate plan/profile sheets for all the utilities.

hope this helps.

good luck,

Are there any videos showing the design process of a cul-de-sac road? I encountered problems while designing a cul-de-sac road. Can someone please provide a step-by-step procedure for building it?
