7.4.11 Trailhead Signs.

Where new trailhead information signs are provided at trailheads on newly constructed or altered trails, they shall comply with 7.4.11.

7.4.11.1 Clear Space.

Trailhead signs shall be located centered at the back of a 30- by 48-inch (760- by 1,220-millimeter) minimum clear floor or ground space. The clear space shall not overlap the trail width but may overlap a resting space or passing space. The slope of the clear space shall not exceed 1:20 (5 percent) in any direction.

7.4.11.2 Sign Contents.

Where new trail information signs are provided at trailheads on newly constructed or altered trails, regardless of whether the trail is accessible, the signs shall include at minimum the following information:

• Length of the trail or trail segment

• Surface type

• Typical and minimum tread width

• Typical and maximum running slope

• Typical and maximum cross slope

• A statement that the posted information reflects the condition of the trail when it was constructed or assessed, including the date of the construction or assessment 

Where more extensive trail information is provided (e.g., an aerial map of the trail and related facilities), the location of specific trail features and obstacles that do not comply with the technical provisions in 7.4 should be identified and a profile of the trail grade should be included.

7.4.11.3 Reach Ranges.

If materials need to be obtained from or manipulated on a sign or kiosk, the sign or kiosk shall be designed to meet the reach ranges in section 308 of the ABAAS.
