This study examined the factors that influence a local government’s decision to engage in regional collaborations. Analysis of 7 local government managers and eleven elected officials revealed that the decision to engage in regional collaboration was influenced by external factors, organizational factors, and internal motivations. Elected officials and local government managers identified a disaster occurrence, fiscal stress, outside agencies, jurisdictional benefit, and communication as key factors. Further, this research highlights the importance of the role of the elected official in intergovernmental arrangements, the role of the local government manager as the policy entrepreneur, and the influence of shared norms and values.
