City and local governments have welcomed public participation, in short-term ways, on issues such as crime prevention, affordable housing, urban planning, service provision, and general budgeting. They have been reluctant, however, to include citizens in substantive, long-term collaborative governance. At a time of budget constraints, multifaceted social problems, declining public trust, changing citizen expectations, and social media transparency, public administrators are motivated to experiment, but only incrementally. Drawing from interviews with reformers, this chapter discusses ad hoc strategies of citizen involvement directed toward specific policy problems, environmental commitments to participation involving multiple forms of citizen engagement, educational innovations such as citizens’ academies, and power-sharing innovations such as participatory budgeting. While some participatory innovations dissipate after a few months, others take root in a self-sustaining civic environment. Factors relevant to sustainability include divisions of labor between citizens and city managers, persistent outreach, substantive work done by citizens, and real power-sharing opportunities.
