According to the Des Moines Regional Skatepark committee, this final design will be the largest open skatepark in the United States. I’m not sure what they mean by “open.” Maybe that’s to counter facilities like Woodward, although they could have said “public” instead. Is there some monstrous indoor skatepark that I’m unaware of? Even the square footage listing of 65,000 is below the official 68,000 listed for Lake Cunningham. I always thought Louisville was largest, but it only weighs in at 44,000 square feet. DMRS is in need of a comprehensive overhead floorpan on their site. California Skateparks designed the park.
