OPTION 1: Living Shoreline Tour


Kirsten Howard, Coastal Resilience Coordinator, NH Coastal Program, Tom Ballestero, UNH Stormwater Center, and David Burdick, UNH Jackson Estuarine Research Laboratory
This project converted a rip rap shoreline into a fringing salt marsh. Site designs included a seaward “habitat rock” sill, imported soils, and geomorphically consistent metrics (slopes, lengths, drainage, etc.) that account for sea-level rise. The project used living shoreline techniques to restore portions of habitat in Cutts Cove by: 1) enhancing the diversity and quality of approximately 60,000 sq ft of mudflat habitat through addition of native shell substrate; 2) partially removing 200 linear feet of shoreline armoring, creating 5,000 sq. ft. of new tidal marsh and a 3,000 sq. ft. vegetated tidal buffer zone; and 3) creating functional connections among tidal habitats and adjacent upland to provide for habitat migration. A new public park will be built landward of the living shoreline project site and will enable higher visibility and educational opportunities for living shoreline approaches in New Hampshire.

OPTION 2: Strawbery Banke Museum & Gundalow Company’s Sheafe Warehouse


Rodney Rowland, Director of Special Projects and Facilities, Strawbery Banke Museum
Strawbery Banke Museum is an authentic 10-acre outdoor history museum dedicated to bringing 300+ years of American history in a Portsmouth waterfront neighborhood to life. The 10-acre museum campus incorporates the Puddle Dock neighborhood, named for its earliest incarnation as a tidal inlet. Though the inlet was long ago filled, it is among the lowest land points in the city and a natural conduit for draining water. This has offered an opportunity for the museum to partner with the city to take a first look how coastal communities are most vulnerable to impacts from a changing climate and start to plan for resiliency. Attendees will tour historic buildings impacted by groundwater rising during extreme high tide events and provide examples of solutions implemented at the museum. more info


Gretchen Carlson, Program Manager, The Gundalow Company
Today, the nonprofit Gundalow Company’s mission “to protect the Piscataqua Region’s maritime heritage and environment through education and action” is more important than ever. Each year, thousands of people spend a few hours sailing onboard the world’s only Piscataqua Gundalow. During our camp and field trip programs, students explore issues like water quality, habitat protection, and stewardship. Our public sail programs include sunset sails, concert sails, speaker sails and more, all with a message that if you experience it – you will care about it, and if you care about it – you will protect it. A recently added exhibition in the Sheafe Warehouse, an historic waterfront warehouse, explores the past, present, and future of the Piscataqua River and Great Bay Estuary through text, images, and interactive displays. Our tour will include visiting the Gundalow docked on the Piscatqua River and experiencing the new Sheafe Warehouse exhibit.
