 The DIY project was begun by skateboarders Bret Taylor, Chuck Willis, Osage Buffalo, Kent Dahlgren, Jay Grahm, and Mark "Red" Scott in the summer of 1990 by pouring concrete against Burnside's main wall, creating a vertical transition obstacle in the empty parking lot below the east-end of the Burnside bridge.The skateboarders found inspiration to do so because the area was covered and protected from Portland's rainy season, allowing the park's riders to skate all year long.With a spare couple of bags of cement, the project was begun.
