Assessing Telecommunications Network Vulnerability to Climate Change Impacts in New England

This study examines the vulnerability of the telecommunications network in New England to climate change, focusing on rising temperatures, extreme weather, and sea level rise. It discusses the current environmental considerations in infrastructure siting and the potential impacts of climate change on wireless communications. The limitations of existing GIS data and lessons from past events like hurricanes are explored, leading to recommendations for future infrastructure planning.

  1. Assessing the Vulnerability of the Telecommunications Network to Impacts from Climate Change: Focus on New England Trevelyn Potter Dr. Patrick Halpin, Advisor

  2. Climate Change Impacts in New England • Increasing temperatures • Increasing precipitation and precipitation intensity • Increase in severe weather • Sea Level Rise

  3. Wireless Communications Infrastructure Siting Overview Wikipedia Wikipedia Thefoa.org www.dasillc.com

  4. Current Environmental Considerations in Siting • National Environmental Policy Act of 1969 • FEMA and the 100 year Floodplain • Wind Zones and Building Codes

  5. Potential Impacts from Climate Change • Flood Damage • Severe Weather • Hurricanes • Wind Damage • Sea Level Rise Wirelessestimator.com

  6. FCC Registered Sites in Connecticut

  7. Town Population Ranking

  8. Priority Ranked Sites

  9. Results Mapping the Vulnerabilities

  10. Floodplain Mapping

  11. Hurricane Inundation

  12. Sea Level Rise

  13. Data Availability for New England

  14. 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

  15. Lessons from the Past • Ice Storm of 1998 • Hurricane Katrina • Hurricane Irene • Hurricane Sandy

  16. 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
