54 A SUMMARY OFACCESSIBILITY STANDARDS FOR OUTDOOR DEVELOPEDAREAS accessibility standards for Federal outdoor developed areas The fire-building surface within a fire ring must be at least 9 inches above the ground (figure 20). Fire rings that are constructed with two concentric walls reduce the chances that people using mobility devices and children will receive burns when the outside wall is touched. The cooking surface must be between 15 and 34 inches above the ground. The cooking surface of pedestal grills may be adjustable beyond the required range, but must include adjustments within the specified range.
