HURRICANE HARVEY FLOOD MAP ARCHIVE

ReferencesįEMA map viewer for Hurricane Harvey resources (flood depths is bottom selection in layers list) See also FEMA's journal of mitigation planning and actions related to Harvey.

Use for determining damage levels on specific structures.

Will include High Water Mark information as it becomes available.

Depth grids updated with new observed peak crest as they become available.

Based on observed Water Levels at stream gauges interpolated along rivers, downsampled to 5m resolution DEM.

Aransas, Nueces, and San Patricio Coastal Depth Grids and Boundaries.

Harris County AOIs and Inundation Boundaries.

One section of the IfSAR data was found to be erroneous, and replaced with a blended 10 meter section. Elevation data comprised a mosaic of 3 meter resampled elevations from 1M & 3M LiDAR, and IFSAR data. High Water Marks were obtained from the Harris County Flood Control District (HCFCD), US Geological Survey (USGS), and other inspection data. This product utilized Triangulated Irregular Network (TIN) interpolation, four quality assurance measures (identifying dips, spikes, duplication, and inaccurate/unrealistic measurements). The raster dataset is contained within an Esri ArcGIS geodatabase.
