A driveway approach is the part of a driveway where the public road meets the private driveway. This section contains several key elements, including the driveway apron, the curb cut, and the end slope. Depending on the slope of the driveway, this area may also contain the trench drain.

Driveways should be sloped with a minimum 2% slope—anything lower will cause precipitation and runoff to collect. A 2% slope is the equivalent of a 2-foot rise over 100 feet. One quick way to check the integrity of your driveway’s slope: no more than four inches of water should collect on the surface longer than 15 minutes after rain.

Common alternatives to a gravel driveway include concrete, asphalt, brick, stone pavers, and permeable pavers. Concrete and asphalt are generally the most affordable options. However, concrete can be prone to cracking in cold climates, while asphalt may soften in areas with high heat and direct sun exposure. For enhanced curb appeal, brick, stone, and permeable pavers are popular choices, though their installation can be more expensive due to intricate designs. Stone pavers offer a natural look and are sometimes installed with gravel around them. Both permeable pavers and brick driveways provide excellent drainage, which helps prevent flooding and reduce water runoff.

In the United States, roads are usually categorized as one of three types: public roads, other drivable roads, and non-drivable roads. These categories dictate how a road can be used; a non-drivable road might be classified that way because it is heavily damaged and unsafe for cars.
