Mitigation Activity Information What type of activity are you proposing? 91.1 -Local Multihazard Mitigation Plan Please select one of the following options to describe the intent of this proposal: Update an existing plan I1elp If updating an existing Disaster Mitigation Act of 2000 plan, or modifying a plan adopted prior to the Disaster Mitigation Act of 2000, please explain. The purpose of the Hawaii County Plan Update is to update County multi-hazard mitigation information and also support the State's mitigation plan. The Plan update will include project data from the following county-level projects: 1) Enhanced Interactive Lava Flow Modeling Program F1owGo II, 2) Mapping of Landslide Hazard Areas, and 3) Area Development Plan for Existing and Future Development. 1) Enhanced Interactive Lava Flow Modeling Program F1owGo II: Will update information to identify at-risk areas, and support the Lava Flow Mitigation Plan, subsumed by reference by the State Multi-Hazard Mitigation Plan. The proposed study will provide updated information to identifying at-risk areas as a lava flow progresses, and assist in locating highest hazard areas as flows approach. At this time, the Kilauea Volcano lava flow is encroaching upon the Royal Gardens subdivision on Hawaii island, and has been repeatedly beset by lava flows since 1983, when the first home to be claimed by lava was first burned by and then overrun by the encroaching and devastating lava flow from the volcano that continues to erupt today. 2)Mapping of Landslide Hazard Areas: The data products from this project will enable improved earthquake loss estimates and analysis in support of the State Multi- Hazard Mitigation Plan and the Hawaii County MultiHazard Mitigation Plan. The emphasis of this study is on potential hazards impacting structures and lifelines, where seismically induced slope instability is significant. The data collected from this study will be used to generate potential hazard maps which could be used to identify already developed as well as future building or development zones that may warrant further detailed evaluation during planning. GIS maps are also planned, which could be used for prioritization of evaluative studies, as well as be used as assessment aids for earthquake damage emergency preparedness. 3) Area Development Plan for Existing and Future Development: This project proposes to refine regulations and policies for new developments, promote community education of precautions and protect existing developments, and provide community outreach in regard to individual protective measures. The Context Sensitive Solutions methodology will be used to identify a comprehensive programmatic approach to mitigate the risks to existing and future development in floodplain areas and to ~spdate and integrate floodplain regulations and laws. To reduce risk and minimize flood damage for existing developments, the study also . proposes to identify and prioritize floodplain mapping for all county districts for flood insurance, to develop policies for unprotected subdivisions, and to coordinate disaster preparedness planning relative to flood events and repetitive loss.
