Semi-circular and roundabout gravel driveways create grand entrances for Tracy estates, allowing smooth traffic flow and easy turnaround. These designs require precise grading of two concentric arcs: the outer curve follows the landscape contour, while the inner curve defines a central island for landscaping or feature lighting. Base layers of crushed stone and quarry process are installed and compacted in matching radii. Decorative top layers—pea gravel or colored crushed stone—highlight the curves. Edging barriers ensure containment along the arcs. Proper drainage swales run parallel to curves, preventing washouts. A semi-circular gravel drive elevates curb appeal and convenience for Tracy properties, blending form and function in a sweeping design.
