Curb Ramp Data Rules and Equivalent Distances

[rbracket]

Ramp Characteristics to record

• Ramp Slope yes = 5 percent slope or les slope between 5.1 and 10 percent steep greater than 10%
• Ramp Surface -surface cracked, truncated half domes destroyed
• Ramp Drainage -puddles visible, weeds growing in gutter, gutter drain in line of travel

  Equivalent Distances (ED) for each condition

  1. Ramp is Good ED=0
  2. deficient Slope (5-10%) ED = 500
  3. deficient Slope(steep): ED=1000 ft
  4. deficient Slope, Drainage: ED=1000 ft
  5. deficient Slope, Drainage, Surface: ED = 2000 ft
  6. deficient Drainage: ED=
  7. deficient Drainage , Surface: ED=
  8. deficient Surface, slope: ED=
  9. deficient Surface: ED=
  10. No Ramp: ED= 10, 000 ft
