Footnotes to Table 802.9.2.2
NOTE: Table 802.9.2.2 is based on providing a spectator in a wheelchair a line of sight over the head of a spectator two rows in front of the wheelchair space location using average anthropometrical data. The table is based on the following calculation: [(2X+34)(Y-2.25)/X]+(20.2-Y) where Y is the riser height of the rows in front of the wheelchair space location and X is the tread depth of the rows in front of the wheelchair space location. The calculation is based on the front of the wheelchair space location being located 12 inches (305 mm) from the back of the seating tread directly in front and the eye of the standing spectator being set back 8 inches (205 mm) from the riser.
The minimum number of wheelchair space locations shall be in accordance with Table 802.10. Wheelchair space locations shall be dispersed in accordance with Sections 802.10.1, 802.10.2 and 802.10.3. In addition, wheelchair space locations shall be dispersed in accordance with Section 802.10.4 in spaces utilized primarily for viewing motion picture projection. Once the required number of wheelchair space locations has been met, further dispersion is not required.
WHEELCHAIR SPACE LOCATION DISPERSION
|TOTAL SEATING IN ASSEMBLY AREAS||MINIMUM REQUIRED NUMBER OF WHEELCHAIR SPACE LOCATIONS|
|Up to 150||1|
|151 to 500||2|

|5,001 and over||7, plus 1 additional space for each 2,000 seats or portions thereof above 5,000|
Exception: Horizontal dispersion shall not be required in assembly areas with 300 or fewer seats if the wheelchair space locations are located within the 2nd and 3rd quartile of the row length. Intermediate aisles shall be included in determining the total row length. If the row length in the 2nd and 3rd quartile of the row is insufficient to accommodate the required number of companion seats and wheelchair spaces, the additional companion seats and wheelchair spaces shall be permitted to extend into in the 1st and 4th quartile of the row.
Wheelchair space locations shall be dispersed at a variety of distances from the event to provide viewing options.
