Chapter 19:Mitigation Stratq, HAWAII COUNTY PROJECT/PROPOSAL SUMMARY LISTING OCTOBER 12,2009 Mitigation Actions for Hurricane and Wind Events Project Description Status Identify high windspeed areas and vulnerable High Windspeed areas are now mapped,and Not effective for new construction until county structures have been adopted in the State Building Code adopts IBC 2006;can be used to evaluate risk to existing buildings Adapt HAZUS-MH or other hazard modeling to Hawaii Incorporate Hawaii building inventory and critical Proposed Planning Project;The HAZUS Island facilities into the HAZUS MH wind risk model. model now has a realistic building inventory Hurricanes will cause much higher losses than for Hawaii and Maui,but it needs to be earthquakes to residential buildings;vulnerable converted to the building modeling scheme structures can be identified with respect to high used for hurricane analysis. wind zones Emergency shelter evaluation;Harden public schools There is a shortage of shelter buildings in Hawaii Proposed Project; for emergency shelters. Of the 14 hurricane shelters County. Perform a 1-year study to identify and Then follow-up with the more detailed DAGS- on the island,only 4 have been evaluated by DAGS: rank Hawaii building types that could be standardized structural evaluation procedure for • Holualoa E.S. deemed safer for hurricane resistance without those public shelter facilities that have higher • Waikoloa E.S.bldg D exhaustive site investigations. Use this vulnerability. • Waikoloa E.S.bldg E screening criteria to determine the number of • Konawaena E.S. low vulnerability buildings available for refuge Perform a comprehensive screening evaluation of in the private sector. This could result in a public hurricane shelters and private sector buildings decrease in the number of persons that would for possible use for refuge report to a public shelter. Hawaii County All-Hazard Assessment of Hurricane This project would conduct onsite building Proposed Project: Shelters:Perform detailed evaluations similar to what construction as-built data collection for the This detailed evaluation will be identifying was done for Hawaii County critical facilities remaining 10 hurricane shelter buildings, priority buildings and providing the information using the more detailed DAGS-standardized necessary to submit PDM grant applications for structural evaluation procedure that follows three to four retrofit projects. the criteria established by the legislature. The three to four facilities with the highest-ranked losses will be taken to a detailed evaluation using Benefit Cost Analysis of potential mitigation measures.
