Bike racks for Sports Arena

Hi, we are working on two Football Stadiums for the next WorldCup. Both are located in dense areas with easy access by bicycle, so pursuing this credit seems like a reasonable intent. The maximum capacity of our largest Arena is 54000 plus 100 FTEs. At 5%, that would make 2705 bike racks required, which is just impossible. Is there another approach to calculate the required bike racks in the particular case of Sports Arenas? Providing bike racks for the staff working on site, FTE, would be acceptable? I've read about similar exceptions in hotels, convention centers, airports and other high capacity buildings. Considering the Arenas will work at its full capacity only during the event, that lasts less than a month. Afterwards, they will be used for concerts and regional games, that is more likely to demand much less of the full capacity. Plus, most transient users carpool or use public transportation. Thanks in advance!
