SRPC has partnered with the NH Coastal Program and other regional organizations on the New Hampshire Setting SAIL project to support municipal efforts to adopt climate adaptation strategies, improve community resilience to coastal flooding, protect public health and safety, and increase awareness of coastal flood risks. Specifically, the Setting SAIL project will provide support for municipal implementation of recommendations from the Coastal Risk and Hazards Commission (CRHC) final report Preparing New Hampshire for Projected Storm Surge, Sea-Level Rise, and Extreme Precipitation (2016). This NHDES Project of Special Merit will fund implementation in the coastal communities in the Strafford region.
SRPC staff will assist Dover with the creation of a climate adaptation master plan chapter. Technical assistance will be provided to Madbury as they identify potential hazards related to climate adaptation, this included a workshop held in fall 2017. SRPC will assist Rollinsford is researching potential funding sources for culvert upgrades. This research included an audit of past applications and communications with state and federal agencies to determine why the town may not have received funding in the past. Kyle will assist the town in the development of a letter of intent, or a framework for applications to be submitted in the future. Durham is relying on SRPC technical assistance as it considers sea level rise scenarios and their possible effects on existing local floodplain regulations, and Newmarket will update its stormwater regulations with assistance from SRPC.
Beginning in June 2016, SRPC partnered with UNH Ph.D student Jayne Knott to complete the Groundwater Modeling of Saltwater Intrusion project in Newmarket. This project was funded by a local source water, and assessed drinking water vulnerability to sea level rise and associated salt water intrusion in the Town of Newmarket.
Deliverables of the project include a computer model and sea-level-rise projections based on different identified scenarios, and a final report, Sea-Level Rise Impacts on Drinking Water: A Groundwater Modeling Study in Newmarket, NH. GIS Planner Rachael Mack and Principal Regional Planner Kyle Pimental presented on the project to the Newmarket Planning Board in June 2017. The final report was approved in June 2016 and can be found at http://new.strafford.org/cmsAdmin/uploads/final_groundwater-modeling-report_001.pdf.
Through the NH Department of Environmental Services, and as a project of special merit, SRPC is currently working on a project entitled Climate Risk in the Seacoast (C-RiSe): Assessing Vulnerability of Municipal Assets and Resources to Climate Change.
This project will develop maps and assessments of flood impacts to the built and natural environment associated with projected increases in storm surge, sea level, and precipitation for ten Great Bay municipalities. Project components include:
This projects will be completed in Spring of 2017.
Partner Organizations: New Hampshire Department of Environmental Services Coastal Program, NH GRANIT, Rockingham Planning Commission and UNH Stormwater Center.
The C-RiSe project is funded by the National Oceanic and Atmospheric Administration under the Coastal Zone Management Act (CZMA) Enhancement Program Projects of Special Merit for FY 2015, authorized under Section 309 of the CZMA (16 U.S.C. § 1456b).

Beginning in the Fall of 2015 SRPC began collaborating with N.H. Sea Grant and UNH Cooperative Extension to plan a program for middle schoolers relative to the effects of climate change. Following this planning process staff from SRPC, NH Sea Grant and UNH Cooperative Extension met with teachers at Oyster River Middle School to get feedback on their ideas, and to discuss how teachers could address topics as part of their curriculum to prepare students for a discussion on climate change and its effects.
In Spring of 2016 Principal Regional Planner Kyle Pimental worked alongside Chris Keeley of N.H. Sea Grant/UNH Cooperative Extension, Amanda Stone of UNH Cooperative Extension and a class of Oyster River Middle School students and teachers to dive into these topics. Their presentation to two middle school classes included supplemental information on climate change and an exercise encouraging students to brainstorm how climate change will affect their communities.
This process culminated with a presentation at the Durham Library allowing student to share what they had learned with their parents and other community members.
As part of Local Solutions for the Strafford Region, Strafford Regional Planning Commission adopted a Climate Change Impacts and Adaptation Appendix in January of 2015. The Climate Change Impacts and Adaptation appendix discusses observed and projected climate change in Southern New Hampshire and the impacts climate change will have on our communities.It dentifies appropriate adaptation strategies to protect assets and address vulnerabilities in the region. This appendix includes an overview of climate change projections in the region and a discussion of both impacts and adaptation strategies in six planning sectors: built environment, human health, water resources, natural systems, agriculture, and society.
This appendix includes several maps at a community and regional level that highlight the vulnerability of critical infrastructure, community assets, and populations. A suite of federal, state, and local programs and resources is included to serve as guidance for communities that seek to increase resiliency to the projected increases in temperature, extreme precipitation events, and sea level and flooding anticipated in this region.
The information, tools, and adaptation strategies provided in this document are intended to assist communities with reducing vulnerability to climate change and proactively responding to the impacts that increases in temperature, extreme precipitation events, and sea level rise will have on the built environment and quality of life.

As explained by the Town of Durham on their website, "the purpose of this project [Climate Adaptation Chapter] was to: conduct research on present climate change and sea level rise estimates using the Piscataqua/Great Bay Report as a backbone; review approaches taken by other states, communities, and agencies in responding to this threat; develop a series of maps identifying areas of increased risk to flooding due to sea level rise specific to Durham; develop strategies that protect areas at risk from flooding due to climate change and sea level rise; and identify various regulatory and non-regulatory options that can be considered by the Town."With funding from the New Hampshire Coastal Program, Strafford Regional Planning Commission (SRPC) provided assistance to the Town of Durham to develop a climate adaptation chapter. This chapter is an appendix to the Durham Hazard Mitigation Plan, and provides adaptation strategies to protect areas of town that are at risk of flooding due to climate change.
