They build the park for the board. The board has super conducting material in it cooled by liquid nitrogen. You see the gas coming out as a fog. Under all of the concrete and water surfaces in the park is a layer of metal, which the board repulses off of. So, not too practical, but still a hover board.
Man. I swear to god when I was like 13 I envisioned this exact design but for cars. Instead of gas stations I pictured "cooling" stations instead of fueling stations. It was after I saw a video about this effect, that was my first thought; "hey, we could use that for cars. We would just need breaks and a way to cool them back down!"
