See attached for my grading vignette attempt - feedback is welcome. I also wrote down the process I followed as I haven't seen this posted by many people - let me know if I am missing any steps. Thanks!
ARE – SITE GRADING VIGNETTE PROCESS
1) Orient building so that long dimension is parallel to contours
2) Calculate min and max slopes (W = I/S) where W = spacing, I = contour interval, and S = slope % in decimal format
3) Place building for proposed level area and set building elevation (see program requirements for extension above adjacent contour line)
4) Create first swale around building envelope – should be as tight to building envelope as possible with fingers at “entry”. Swale should be as close to building envelope as possible
5) Adjust contours around first swale as required with swales pointing up towards higher elevation, maintaining max and min spacing with sketch circles. Measure spacing between swales with sketch lines, making sure not to exceed max spacing
6) Only adjust contours that are required
7) Double check solution avoiding all drip lines and property lines!
