New Hampshire Coastal Flood Risk Summary and Public Input Opportunities
New Hampshire Coastal Flood Risk Summary

Pursuant to RSA 483-B:22 the New Hampshire Department of Environmental Services (NHDES) has convened a 2019 Science and Technical Advisory Panel (STAP) Steering Committee comprised of representatives from the New Hampshire Department of Transportation (NHDOT), Division of Homeland Security and Emergency Management (HSEM), Office of Strategic Initiatives (OSI), Fish and Game Department (NHFG), Department of Natural and Cultural Resources (DNCR), Department of Administrative Services (DAS), Rockingham Planning Commission (RPC), Strafford Regional Planning Commission (SRPC), and University of New Hampshire (UNH). The STAP Steering Committee is supervising the updating of storm surge, sea-level rise, precipitation and other relevant projections originally summarized in the New Hampshire Coastal Risk and Hazards Commission Science and Technical Advisory Panel (STAP) 2014 report, "Sea-Level Rise, Storm Surges, and Extreme Precipitation in Coastal New Hampshire: Analysis of Past and Projected Future Trends Adobe Acrobat Reader Symbol." The 2019 New Hampshire Coastal Flood Risk Summary update is comprised of two parts, including a summary of best available science (Part I) and guidance for how to use the science in decision-making (Part II – DRAFT).

New Hampshire Coastal Flood Risk Summary – Part I: Science

Published in August 2019 by the University of New Hampshire, "New Hampshire Coastal Flood Risk Summary – Part I: Science" provides a summary of the state of the science relevant to coastal flood risks in New Hampshire and includes updated projections of relative sea-level rise, coastal storms, groundwater rise, precipitation and freshwater flooding for coastal New Hampshire. This information is the scientific foundation for "New Hampshire Coastal Flood Risk Summary – Part II: Guidance for Using Scientific Projections (DRAFT)."

"New Hampshire Coastal Flood Risk Summary – Part I: Science" was developed by a group of scientific advisors from the University of New Hampshire and reviewed by 2019 STAP members and an external panel of regional experts. The final document was accepted by the 2019 STAP Steering Committee on June 28, 2019.

New Hampshire Coastal Flood Risk Summary – Part II: Guidance for Using Scientific Projections (DRAFT FOR REVIEW)

"New Hampshire Coastal Flood Risk Summary – Part II: Guidance for Using Scientific Projections (DRAFT)" builds upon Part I and provides draft guidance for using the updated scientific projections of coastal flood risks in New Hampshire. Specifically, the draft guidance provides overarching principles and a step-by-step approach for incorporating updated projections for relative sea-level rise, coastal storms, groundwater rise and extreme precipitation into state and local land use planning and decision-making.

Public Input Opportunities

The 2019 STAP is seeking public input on the "New Hampshire Coastal Flood Risk Summary – Part II: Guidance for Using Scientific Projections (DRAFT)" throughout the month of September 2019.

Interested state and local government officials; professional planners; consultants involved in land use planning, zoning, permitting, land development, conservation, and natural resources management; and members of the public are encouraged to attend free public workshops to provide input on the draft guidance. Interested parties can pre-register for a public input workshop by following the links below.

The Public Input Workshops will be held on:

Tuesday, September 10, 2019, 4:45-7:30pm
Seacoast Science Center

REGISTER on UNH Event Portal

Wednesday, September 11, 2019, 4:45-7:30pm
Newmarket Millspace

If you cannot attend a workshop or if you would like to provide additional input following a workshop, written comments on the draft guidance may be submitted via an online survey.

The deadline to submit comments on the "New Hampshire Coastal Flood Risk Summary – Part II: Guidance for Using Scientific Projections (DRAFT)" is Monday, September 30, at 4 p.m.

Funding for this project was provided by the National Oceanic and Atmospheric Administration Office for Coastal Management under the Coastal Zone Management Act in conjunction with the NHDES Coastal Program.
