New Hampshire’s Department of Environmental Services administers the Climate Risk in the Seacoast (C-RiSe) project which is intended to provide municipalities along the Great Bay with the resources they need to assess sea level rise and storm surge flooding. The Great Bay communities that have been assessed include: Rollinsford, Dover, Madbury, Durham, Newmarket, Newfields, Exeter, Stratham, Greenland, and Newington. This project is funded through the Coastal Zone Management Act by the National Oceanic and Atmospheric Administration (NOAA).

Patterns and Projections of High Tide Flooding Along the U.S. Coastline Using a Common Impact Threshold
The National Oceanic and Atmospheric Administration (NOAA) analyzes "high tide flooding" (also known as "nuisance flooding") in this report, and finds that it is becoming more commonplace due to sea level rise. High tide flooding impacts roads, beaches, parks, and private property, and is generally more disruptive than damaging. However, there are places such as Norfolk, Virginia; San Diego, California; and the U. S Marshall islands where it is currently a serious problem. Even more, with continued sea level rise, flooding is likely to increase.

New Hampshire Senate Bill (S.B.) 285: Establishing a Coastal Resilience and Economic Development Program
August 3, 2019
On August 3, 2019, the State of New Hampshire passed Senate Bill (S. B. ) 285 to establish a coastal resilience and economic development program and provide local governments with innovative new tools to address climate emergencies due to sea-level rise, storm surge, and flooding. One notable provision of the bill allows municipalities to either alter their existing boundaries or create a new municipality by combining existing ones (Section 2, codified in New Hampshire Revised Statutes § 31:9-d).

Managing the Retreat from Rising Seas — Hampton, New Hampshire: Community-Driven Climate Adaptation Planning Process
July 15, 2020
The coastal town of Hampton, New Hampshire has identified the need for long-term climate adaptation planning to address the impacts of sea-level rise and improve community resilience to coastal flooding through a state-local, public-private partnership. This ongoing adaptation planning process that started in 2018 is being led by the Seabrook–Hamptons Estuary Alliance (SHEA) — a local conservation nonprofit — with support from others including the New Hampshire Department of Environmental Services Coastal Program (NH Coastal Program) and town officials and staff. The approach taken by SHEA and the NH Coastal Program offers a unique example of community-driven, multifaceted planning focused on informing and educating the community through a series of workshops and surveys to gauge awareness and opinions across a range of different adaptation strategies. The adaptation strategies presented to the community for consideration include: protection (“keep water out”), accommodation (“live with water”), and managed retreat or relocation (“get out of the water’s way”). The results of these efforts are being used to inform local actions going forward. Policymakers and planners in other municipalities may find Hampton’s work instructive for how to increase awareness of the benefits and tradeoffs of retreat across a spectrum of adaptation strategies at the outset of community-driven, public-private decisionmaking processes. This case study is one of 17 case studies featured in a report written by the Georgetown Climate Center, Managing the Retreat from Rising Seas: Lessons and Tools from 17 Case Studies.
