New Hampshire Coastal Flooding

New Hampshire, despite having a very short coastline, has taken strong action to address its current coastal flooding risks. But aside from an adaptation plan developed specifically for the transportation sector, the state has taken far less action than the majority of coastal states to prepare for sea level rise.



For more information on how prepared New Hampshire is for its growing coastal flooding threat, read the detailed state summary.


Is New Hampshire Taking Action?

  • Besides the transportation sector’s Potential Impacts of Climate Change on Transportation Infrastructure report, which serves as a climate change adaptation action plan for that sector, the state has not taken action to develop a comprehensive, statewide climate change adaptation plan
  • New Hampshire has also taken limited steps to implement resilience strategies and there is no evidence of dedicated sources of funding to improve resilience against climate change-related coastal flooding
  • New Hampshire's Hazard Mitigation Plan includes programs to reduce the current impacts of coastal flooding on the transportation, energy, water, health, and community sectors

Did you know...

  • Among the 22 coastal states assessed, New Hampshire has a below average area currently in the 100-year coastal floodplain – less than 10 square miles. By 2050, this is projected to increase only slightly
