Local plan implementation: assessing conformance and influence of local plans in the United States

Attention to if and how plans are implemented is increasing. Among the conceptions of plan implementation used by scholars, plan conformance and plan performance are most prominent, though rarely have both been assessed in a single study. We assess plan conformance and a modified version of performance, which we call influence, for a sample of more than 100 local hazard mitigation plans developed in response to a national planning requirement in the United States. Our findings indicate that progress on implementation of the policies included in the plans (plan conformance) is moderate, but that the rate of progress varies widely by the type of policy and the state in which the local jurisdiction is located. The findings also indicate that coordination of hazard mitigation plans (plan influence) is strongest with other emergency management agencyled planning initiatives and weaker with planning initiatives led by other agencies. National officials interested in advancing local implementation of national goals need to consider the degree to which state and local governments are given autonomy to select and prioritize local policies included in plans, as well as constraints on coordination across planning initiatives.
