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
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
