New Hampshire Silver Jackets

A team of individuals from both federal and state agencies that will focus on New Hampshire’s flood risk management priorities and provide technical expertise and resources in the development of solutions and projects when possible. The New Hampshire team’s interagency agreement was finalized in January 2015.

Mission Statement

Maintain and integrate comprehensive relationships with federal, state and local agencies and programs to increase awareness and reduce flood risk and facilitate partnerships related to mitigating and recovering from flooding events in New Hampshire. Establish an interagency approach to sharing and combining resources, including funding, programs and technical expertise as appropriate. Recommend and facilitate the collaborative implementation of strategic measures to proactively reduce the risks of flooding in New Hampshire and provide coordinated assistance to communities and individuals after a flooding event.

Goals and Tasks

  • To build a strong team of agencies and programs with specific skills and knowledge related to flood risk identification and mitigation. 
  • To advise and assist New Hampshire communities in their efforts to become more resilient and less vulnerable to flood hazards. 
  • To increase public awareness and understanding of the risks and mitigation of flood hazards through the sharing and uniform delivery of information and resources to the 
    communities of New Hampshire. 
  • To foster partnerships and facilitate cooperation in achieving flood risk reduction. 
  • To assist with the prioritization of risk management tasks during individual flood incidents.

Team Activities

New Hampshire Team Welcomes the National Weather Service

At the New Hampshire Silver Jackets Team quarterly meeting on March 27, 2017, the team unanimously voted to add their newest member, NOAA - National Weather Service from Gray, ME, who then signed the team's interagency agreement.

New Hampshire Ice Jam Assessment and Outreach Project

On December 5, 2016, the NH Silver Jackets Team kicked off its second project, which includes partnering with the U.S. Army Corps of Engineers’ Cold Regions Research and Engineering Laboratory (CRREL).  Since New Hampshire’s rivers are prone to ice jams and local officials often seek technical assistance from the state, the project will seek to enhance the Team’s understanding of ice jam science, increase the state’s ice jam response capability, and develop tools to address and mitigate ice jams.  The project will focus specifically on the Gale River at Franconia and Sugar Hill, which experienced ice jams and related flooding in 2012 and 2016.  The project will include: an assessment of existing conditions and recommend channel modifications, if appropriate; a geomorphic assessment to identify morphological changes that may have prompted ice jam formation; and production of an outreach package, to include Ice Observer Training, an item in the state’s Hazard Mitigation Plan.

Hinsdale Flood and River Vulnerability Assessment and Risk Communication Project

Hinsdale Site VisitIn November 2016, the NH Silver Jackets Team finalized the report for their first project, a flood and river vulnerability assessment and risk communication project for the Town of Hinsdale.   The project began in Spring 2015 when the Team was contacted by the U.S. Environmental Protection Agency (EPA), who asked for assistance with one of their grant projects, which was to assess the drinking water and wastewater infrastructure vulnerability in the Town of Hinsdale.  When the Team met with Hinsdale town officials, they requested additional assistance with flood-related concerns specifically those related to Kilburn Brook, which had experienced at least two flood events since 2005.  As a result, the Team’s first project was developed and approved in July 2015. Under the project, the following activities were completed: an assessment of Kilburn Brook to assist in understanding potential future hazards; an assessment of selected stream crossings in Hinsdale to provide information on those most at risk from river process compatibility and aquatic organism passage; provided the town a copy of the U.S. Army Corps of Engineers’ Dams Flood Emergency Plan for Otter Brook Dam and Surry Mountain Dam, an item in their hazard mitigation plan; and provided an assessment and recommendations about Hinsdale’s floodplain management program.  The project provided the town with the necessary data and information to move forward with addressing the identified flood risks.
