Detention Pond Grading

[tim_newsome]

I am starting with a bottom of pond Feature Line. The Feature line starts at 121.80' elevation and continues around the bottom perimeter of the pond until it reaches the bottom at 121.0' elev then makes the positive slope back up and around the other side of the bottom of the detention pond until it comes back to 121.80' elev.

My top of pond is going to have an Elevation of 125.50'. I am not certain what the best way to target 125.50' for the crest of my pond is. Please ignore the desire of any other BMP design here. I am just simple looking for a way to grade the bottom of the pond Feature Line which has a very mild slope to a complete perimeter crest at an exact elev of 125.50' completely around the pond?

do you have a slope for the pond sides?

[tim_newsome]

Yes, 3:1 side slopes for the pond.

I would use the Grading Creation Tools. Within these tools, there are different grading sets. If you do not have the desired grading method created within the set, you can easily create one. You will want to choose a method to grade to a specific elevation at a slope of 3:1.
