Chapter 6 looks at the world of official urban planning and placemaking, providing different perspectives on its relationship to DIY urbanism. Through the voices of professional planners, the chapter explores their conflicted opinions on DIY approaches: criticizing their informality and emphasizing the importance of regulations and accountability for everything from basic functionality to social equity, yet sympathetic to do-it-yourselfers’ frustrations and often excited to adopt their tactics, harness their energy, and exploit their cultural value. The chapter then describes how some DIY projects have found pathways to formal adoption and inspired popular “tactical urbanism” and “creative placemaking” approaches to public space design. Many such interventions can result in innovative public spaces with social, environmental, and economic benefits. But the reproduction of an aesthetic experience selectively inspired by a hip grassroots trend and combined with “creative class” values can mark the resulting spaces themselves as elite and exclusionary.
