County of Hawaii Mufti -Hazard Mitigation Plan Executive Summary <br />risk and to gauge the potential impacts of each hazard of concern on the island of Hawaii. The risk assessment <br />included the following: <br />• Hazard identification and profiling <br />• Assessment of the impact of hazards on physical, social, and economic assets <br />• Identification of particular areas of vulnerability <br />• Estimates of the cost of potential damage. <br />Based on the risk assessment, hazards were ranked for the risk they pose, as shown in Table ES-1. <br />_ .. -. ;. - ._�_•__ fable ES-'f.

Utilize state-of-the-art methods and technologies as well as local knowledge to identify hazards, risks, and <br />capabilities. <br />2. Ensure that all critical facilities and infrastructure withstand hazard incidents and have contingency plans <br />to restore services quickly. <br />3. Protect natural and cultural resources to the extent practicable while mitigating hazards. <br />4. Promote actions that support land use planning and regulations designed to ensure long-term resiliency. <br />5. Promote community risk reduction and preparedness through public education, training and awareness. <br />6. Improve capabilities to implement response protocols and continuity of operations and services. <br />7. Strengthen partnerships and leverage existing resources and capabilities to identify, assess, and reduce the <br />impact of hazards. <br />The effectiveness of a mitigation strategy is assessed by determining how well these goals are achieved. <br />Objectives were identified that meet multiple goals. The objectives also are used to help establish priorities. The <br />objectives are as follows: <br />1. Improve warning and emergency communications systems. <br />2. Conduct studies to determine locations, potential impacts, and links among threats, hazards, and <br />vulnerabilities to support the identification and implementation of mitigation and protection measures in <br />Hawaii County. <br />I TETRA TECH <br />
