WHAT IS MITIGATION? Mitigation is a sustainable action that will reduce or eliminate injury to citizens, damages to structures and allow continuity of critical society function. Types of mitigation projects include: n n n Property Protection Structural Prevention Emergency Services Natural Resource Protection Public Education and Awareness
