Driveway Planning Guide

How to Measure Your Driveway

  1. Measure the length of your driveway in feet.
  2. Measure the width at several points if it varies.
  3. For irregular driveways, divide into rectangular sections.
  4. Calculate the area of each section and add them together.
  5. For curved driveways, approximate with straight sections.

Additional Considerations

  • Base material: Most driveways require a 4-6 inch gravel base.
  • Drainage: Ensure a slight slope away from buildings (about 1/8″ per foot).
  • Climate: In freeze/thaw areas, deeper bases may be necessary.
  • Reinforcement: Consider rebar or mesh for concrete in high-stress areas.
  • Permits: Check local regulations before starting your project.
