The adjacent concrete curb and gutter assembly includes a twelve-inch border with quarter-inch by quarter-inch grooves at three-quarters of an inch on center typically, alongside tooled half-inch radius edges and a trowled finish. A half-inch expansion joint is provided at sixteen feet on center maximum and at curve tangents and corners. The concrete paving rests on an eighteen-inch minimum base over natural grade, with finish grade established at one inch at sod and one and a half inches at ground cover. The ramp slope is set to one in twenty maximum, with a half-inch bevel at two to one.
