Understanding Elevation Grade

What is Grade?

Grade (or slope) represents the steepness of an incline, commonly used in construction, landscaping, and road design. It can be expressed as a percentage, degree angle, or ratio.

Common Applications

  • ADA ramp compliance (maximum 8.33% grade)
  • Driveway design (typically 10-15% maximum)
  • Proper drainage (minimum 2% for water flow)
  • Road construction (usually under 7% for safety)
