Parking Lot Surface III

In this post I'll remove on of the low points I don't want. I really don't want to have a second low point if I don't need to have it. I'll remove it by directing water around the landscaped area that juts out into the parking area.

I find it quicker to delete the top of curb if I need to make any changes rather than trying to remember what PVI's I've changed and which ones I haven't. After deleting the top of curb I use the Quick Elevation edit to change the slope of the feature line.

I'm using the corner cleanup as the starting elevation and going 2% up from that on both corners. Once I have the grades adjusted I offset it to get the top of curb.

Since I like symmetry I'll add some more feature lines to make the TIN Triangles look symmetrical and it also helps when the surface parking lot is more complicated than this example.
