Your city or county will have guidelines about the minimum and maximum width and length of private roads. The average private road is 12 feet wide, and length, of course, depends on your property. Requirements also depend on the amount of traffic and types of vehicles your road experiences. Check with local ordinances before planning a road on your property.

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.

While some areas may allow for a slope of up to 20%, this is often the maximum slope for driveways, with a few exceptions of up to 25%. Other regions may have a maximum of 12%, 15%, or 18%, so check with your local building department to ensure you’re laying a driveway that is up to code for your location.

Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer. Above the gravel, you’ll often find coarse sand that helps reduce paver shifting over time. Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.
