Building a road on a slope requires careful planning and will normally require a drainage system underneath to prevent flooding and damage to the road over time. Your professional may lengthen your road to create switchbacks if the slope directly to your home is too steep, as there are regulations for maximum road slope. The drainage system will help prevent runoff from the higher side of the slope from damaging the asphalt or concrete. Keep in mind that building a road on a slope isn’t a good DIY project, as a lot can go wrong.

Driveway paving costs around $4,500 on average, but depending on many factors, you could pay anywhere from $2,500 to $6,600 or more. The size of your driveway will usually be the most significant factor, with more square footage increasing your costs. You can expect to pay between $2 and $15 per square foot for paving services. Some other factors that play a role include the following:

• Quality of the materials

• Contractor’s experience and expertise

• Site preparation and grading, if necessary

• Layout of your driveway

Yes, a paved or repaved driveway can boost your home's value by increasing its curb appeal and the functionality of your outdoor space. A new driveway can add anywhere from $5,000 to $20,000 to a property's value. An old, crumbling driveway can be a red flag for potential buyers and inspectors.

The amount of value added depends on the materials used, the design, and local market conditions. Concrete is often cited as adding the most value due to its long lifespan, though asphalt may be more desirable in colder climates. The return on investment is greatest when replacing a driveway that is in poor condition; repaving a driveway that is already in good shape will not yield as significant an increase in value.

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.
