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
