Parking Space Slopes Exceeding the Allowable Slopes

Last month we discussed a study that found 95 percent of all ADA lawsuits filed contain an issue regarding parking spaces. We’ll continue our series on the top 20 Americans with Disabilities Act (ADA) compliance issues seen in truck stops and travel plazas by discussing parking space slopes.

Last month we discussed a study that found 95 percent of all ADA lawsuits filed contain an issue regarding parking spaces. We’ll continue our series on the top 20 Americans with Disabilities Act (ADA) compliance issues seen in truck stops and travel plazas by discussing parking space slopes.

In section 502.4 of the 2010 ADA Standards for Accessible Design it states that slopes not steeper than 1:48 (2 percent) shall be permitted. Access aisles shall be the same level as the parking spaces they serve. Changes in level are not permitted.

Built-up curb ramps are not permitted to project into access aisles and parking spaces because they would create slopes greater than 2 percent.

Car parking spaces shall be 96 inches wide minimum and van parking shall be 132 inches wide minimum, shall be marked to define the width and shall have an adjacent access aisle.

As with parking spaces access aisles are required to be level in all directions to provide a surface for wheelchair transfer to and from vehicles. The slope, allowing for drainage, cannot be steeper than 2 percent. Below are some additional requirements for access aisles.

  • Access aisles serving car and van parking spaces shall be 60 inches wide minimum.
  • Access aisles shall extend the full length of the parking spaces they serve.
  • Access aisles shall be marked so as to discourage parking in them.
  • Access aisles shall not overlap the vehicular way.
  • Access aisles shall be permitted to be placed on either side of the parking space except for angled van parking spaces which shall have access aisles located on the passenger side of the parking spaces.
  • Two parking spaces shall be permitted to share a common access aisle. Access aisles shall adjoin an accessible route.
  • Accessible routes must connect parking spaces to accessible entrances. 

I look forward to continuing this series next month when we’ll discuss curbs ramps along accessible routes with greater than the allowable slopes.
