Where Do I Start?
Selecting Projections to Help you
Plan for Coastal Flooding

In March 2020, the NHDES Coastal Program, UNH Extension, Piscataqua Region Estuaries Partnership, and NH Sea Grant held two webinars to provide an overview of the NH Coastal Flood Risk, including the Science key findings and the newly released final Guidance. These were held as webinars due to the COVID-19 virus, but additional in-person and interactive trainings will be scheduled in the future when it is safe to do so. 

Recordings of the two webinars are available below.

Webinar description: Coastal flooding is already happening in New Hampshire and is expected to increase with sea-level rise and other climate changes. Planning for coastal flood risks is essential to save lives and money, sustain quality of life, and minimize damage to New Hampshire’s most vulnerable coastal areas. Join us to learn how you should use the 2019-2020 NH Coastal Flood Risk Summary Science (Part I) and Guidance (Part II) in your decision-making.

The 2019-2020 New Hampshire Coastal Flood Risk Summary is comprised of two parts, including Part I: Science and Part II: Guidance for Using Scientific Projections. Part I provides a summary of best available science relevant to coastal flood risks in New Hampshire, including updated projections of sea-level rise, coastal storms, groundwater rise, precipitation and freshwater flooding. Part II provides science-based and user-informed guiding principles and a seven step approach for incorporating updated coastal flood risk projections into planning, regulatory, and site-specific decisions. Together, Part I and Part II fulfill the requirements of RSA 483-B:22, which directs the NH Department of Environmental Services (NHDES) to supervise updates to the 2014 Coastal Risk and Hazard Commission Science and Technical Advisory Panel report, Sea-Level Rise, Storm Surges, and Extreme Precipitation in Coastal New Hampshire, Analysis of Past and Projected Trends, at least every five years.
