Chapter 19:Mitigation Strate,U HAWAII COUNTY PROJECT/PROPOSAL SUMMARY LISTING OCTOBER 12,2009 Project Description Status Conduct Public Meetings on VOG and how to mitigate it's effects Supplement with studies to Proposed Project document the rate of removal(efficacy)of the various proposed VOG mitigation techniques Hazard Information GIS Mapping Public Website: Parcel-based one-stop multi- Proposed Project,Some of the The architecture would be to allow a client to enter a TMK,an address,or a ZIP hazard lookup;the website maps may not yet have been code,and then be able to bring up a sequence of maps relevant to that location. must be easily and reliably developed;it would be If the TMK or address was entered,then that location would be flagged or maintained. advisable to consult with highlighted,on each map;if a ZIP code is entered,then the ZIP code area respective domain experts on covered would be highlighted. For each hazard,the client would be able to the types of information that bring up maps for each threat associated with the hazard. The client could then can be provided and the level click through to additional information on:what structures are most vulnerable of effort that would be required to the threat;how to mitigate for that particular threat;and links to additional to be both useful and cost- information on the threat. effective for this effort.
