A six-inch vertical reverse curb and gutter profile is formed in concrete with a total width of two feet zero inches and an overall height of ten and one-half inches. The top vertical face features a one-half-inch radius top corner and a six-inch top width before transitioning with a one-inch radius into a three-and-one-half-inch radius curve with a plus-or-minus one-half-inch tolerance. The gutter pan slopes at a one-inch batter toward the outer edge, terminating at a seven-inch overall height. The entire concrete assembly rests on a four-inch aggregate base layer.
