This page provides an overview of the steps New Hampshire is taking to prepare for the impacts of climate change.

In December 2007, Governor John Lynch established a Climate Change Policy Task Force and directed the Task Force to develop a Climate Action Plan for the state (Executive Order 2007-3). The Task Force was composed of 29 members including regulators, scientists, business leaders, utility representatives, and environmental groups, and was chaired by the Commissioner of New Hampshire’s Department of Environmental Services (DES); it included a work group focused on adaptation. On March 25, 2009, the Task Force released the New Hampshire Climate Action Plan, which includes a chapter on Adapting to a Changing Climate (Chapter 3) and called for the state to create a stand-alone climate change adaptation plan. Additionally, as recommended in the plan, the state subsequently established the New Hampshire Energy and Climate Collaborative to facilitate the implementation of the plan's recommendations by bringing together leaders from all sectors of society — government, business, nonprofits, and academia.

Legislation Supporting State-Level Adaptation

In 2013, the New Hampshire legislature created the Coastal Risk and Hazards Commission (NHCRHC) and charged it with recommending “legislation, rules, and other actions to prepare for projected sea-level rise and other coastal and coastal watershed hazards . . .” The commission included members of the state House of Representatives and Senate, state agencies, academic institutions, regional planning commissions, one representative from every coastal community, and representatives from the insurance, building, and emergency planning sectors. The commission sunset in 2016 after the release of its final report, Preparing New Hampshire for Projected Storm Surge, Sea-level Rise, and Extreme Precipitation. The report assesses climate vulnerabilities in the state’s coastal areas; identifies barriers to incorporating climate change science and information into planning and practice; and recommends adaptation policies for the state legislature, state agencies, and coastal municipalities.

In May 2016, the state passed Senate Bill (SB) 374 mandating DES to convene and supervise a multi-agency team to update and summarize coastal flooding trends based on sea-level rise, extreme precipitation, and storm surge projections in a 2014 report by NHCRHC, Sea-Level Rise, Storm Surges, and Extreme Precipitation in Coastal New Hampshire: Analysis of Past and Projected Trends. These trends must be updated every five years beginning July 1, 2019. SB 374 implemented one of NHCRHC’s recommendations in its 2016 final report to ensure that New Hampshire is acting on and referencing the most up-to-date science.

In June 2016, the state legislature passed SB 452 “requiring state agencies to conduct an audit of laws governing coastal regions” to enable them to take “appropriate actions” to better prepare for climate-related risks, such as storm surges, sea-level rise, and precipitation events. The audit is expected to be completed in 2018. In addition to the audit, some state agencies have been actively engaging in adaptation planning since 2009. For example, DES incorporated climate change into its 2010-2015 Strategic Plan, to consider climate change in all DES programs and activities.

Also in June 2016, the state legislature passed SB 376-FN requiring the New Hampshire Fish and Game Department to identify existing and needed wildlife corridors for connecting habitats in the state to support wildlife resilience in light of climate change and development pressures. The legislation also calls on the Fish and Game Department to make recommendations about any legislative changes needed to enhance the state’s wildlife corridors.

Legislation Supporting Local Adaptation

In 2013, the legislature passed Senate Bill 164 (Revised Statutes § 674:2 II) that authorized municipalities to incorporate coastal management provisions in master plans (i.e., local land-use plans) to address the loss of property that can result from projected coastal risks due to increasing frequency of storm surge, flooding, and inundation.

In 2017, the New Hampshire legislature passed legislation enabling municipalities to create a tax incentive program to encourage resilience in coastal areas (New Hampshire Revised Statutes § 79-E:4-a). Municipalities can establish “Coastal Resilience Incentive Zones” in their jurisdictions to grant property owners tax relief for undertaking “resilience measures” for qualified properties or structures identified by storm surge, sea-level rise, or extreme precipitation projections.
