An Adaptation Plan could be the same as a Hazard Mitigation Plan (HMP) or a Climate Action Plan (CAP), but it may not be. A HMP could be absent of climate hazards (or at least not include projections), and a CAP could be focused solely on mitigation. FEMA's latest guidelines direct local governments to include climate change in their HMPs but don't specify requirements for doing so. The question is the difference between the adaptation plan and HMP. The HMPs are about reducing harm to people from disturbances. Adaptation addresses the full spectrum of negative impacts from climate change, including chronic impacts to secondary human systems (economic, health, infrastructure, etc.) and natural systems.
