Tactical urbanism Tactical urbanism includes low-cost, temporary changes to the built environment, usually in cities, intended to improve local neighborhoods and city gathering places. Tactical urbanism is also commonly referred to as guerrilla urbanism, pop-up urbanism, city repair, or D.I.Y. urbanism. The Street Plans Collaborative defines "tactical urbanism" as an approach to urban change that features the following five characteristics: A deliberate, phased approach to instigating change; The offering of local solutions for local planning challenges; Short-term commitment and realistic expectations; Low-risks, with a possibly high reward; and The development of social capital between citizens and the building of organizational capacity between public-private institutions, non-profits, and their constituents.
