Analyzing the Extent of Flooding Impacts Using Site Specific Analysis and User Generated Depth Grids
• Contract with ImageCat• Engaged Catastrophe Assessment Network
(CAN) analysts in academia and outside U.S. • Completed in 3 days over July 4th weekend• Joined assessments with parcel and IA data• Completed detailed assessment of large loss
structures (schools, significant facilities)• $35,000 or $17 per impacted structure assessed
• Coordination with USGS to collect perishable data (high water mark collection).
• Pictometry Oblique Arial Imagery• New Light/ImageCAT Damage Assesment
Rapid turnaround Damage Assessment needed
Damage Assessment Accomplished using the following:
Near Real Time Results:
• Number of structures impacted by flood event• Approximate depth of water at each impacted structure• HAZUS site specific derived financial impacts• Established an SOP(Standard Operating Procedure) for rapid
turnaround Damage Assessments.
• Digital Globe Satellite Imagery• Houston Engineering• FEMA Region VIII Risk
• Preliminary inundation maps were produced for anticipated peak flows and sent into the field
• USGS captured locations (using Real Time Kinematic (RTK) GPS techniques) of the temporary levees and high water marks used to calibrate inundation depth model.
• Most critical component to Rapid Turnaround Damage Assessment• Coordination with community• Coordination with private sector• Coordination with Federal, State, Local, and Tribal partners• Rapid evaluation of population and building exposure to flood event• Publically published maps gave displaced citizens a opportunity to
