Hazus Flood Senario Analysis

Above is a highway bridge damage and functionality analysis using Hazus-MH. A total of four bridges have been estimated to sustain flood damage and I have chosen to delineate three of them here because disaster recovery in this area could be substantially hindered due to the possible closures of these bridges being in such close proximity to each other. A total loss of 14,000 thousand dollars of damage is predicted, a number that would seem to predict minor damage and with a bid of pre-flood engineering could possibly eliminate all damage to these bridges. Above is a map of total estimated religious building loss using Hazus-MH. a total of nearly 9,000 square feet of total damage has been predicted to occur to all religious buildings within the analysis area. The damage results for this scenario seems somewhat low but is an important consideration because it can be the first place many displaced households will want to take shelter at.
Above is a total estimated building loss calculation using Hazus-MH. Regional statistics include 73 square miles, 2,821 census blocks and 6,3883 total buildings. It is estimated that 178 house holds will be displaced and 454 people will need short term shelter. Economic loss is predicted at nearly 58 million dollars and a total property loss of nearly 127 million dollars. Above is a debris estimation calculation using Hazus-MH. Regional statistics include 39 square miles, 1,978 census blocks and 40,637 total buildings. It is estimated that 814 households will be displaced and 1,889 people will need short term shelter. Economic loss is predicted at nearly 58 million dollars and a total property loss of nearly 127 million dollars. Based on these results a debris estimation calculation would be of great necessity for disaster mitigation. This map illustrates total debris estimation based on finishes, structures and foundations.
