For instance, Portland’s open rules towards food vending have allowed local food truck entrepreneurs to occupy vacant spaces and create vibrant uses out of them—it has been a boon for local businesses and has encouraged tourism to the area (Southworth, 2014). Temporary land uses encourage experimentation. Across the United States, local skateboarders have taken over vacant lands—often unused public land underneath bridges—to build illegal skateparks (e.g., Burnside Park, Portland, Washington Street Park, San Diego).
