Extents of Hurricane storm surge inundation study <br /> Transects were laid-out within the study limits and representative placement was evaluated <br /> during the field reconnaissance performed from July 24th through August 6`h, 2007. The <br /> topographic base consisted of LiDAR collected under FEMA Task Orders 12 and 26. The <br /> LiDAR data were collected in the Fall of 2006, post-processed to bare earth and quality <br /> controlled to meet FEMA mapping standards. These data were assimilated together with the <br /> best available bathymetric datasets, including USACE hydrographic LiDAR, into high- <br /> resolution seamless digital elevation models. <br /> The hazard analysis considered the combination of storm surge and hurricane-induced wave <br /> hazards. This included independent analysis and/or modeling of storm surge, return <br /> frequency flood elevations, wave setup, overland wave hazards, and wave runup. The <br /> ADvanced CIRCulation model for coastal ocean hydrodynamics (ADCIRC) was selected to <br /> develop the stillwater elevations or storm surge for the study area.
