Limitations of Existing GIS Data Not all structures are registered with the FCC Digital flood mapping is not available for all areas, particularly rural ones Hurricane Inundation data not broken down into categories for all areas Lack of LIDAR-based and local scale sea level rise mapping for many coastal areas Lack of fine-scale GIS wind data applicable to infrastructure of this type
Lessons from the Past Ice Storm of 1998 Hurricane Katrina Hurricane Irene Hurricane Sandy
Recommendations for the Future Consider areas of current “moderate risk” like 500 year floodplains and adjacent areas when making siting decisions Implement registration requirement for all licensed antenna sites Avoid projected coastal inundation areas Develop uniform regional or national data sets for vulnerability assessments
