Alaska Silver Jackets

The Alaska Silver Jackets team intends to serve as a catalyst in developing comprehensive and sustainable solutions to flood hazard issues including mitigation planning, flood hazard mapping, risk reduction activities and response and recovery planning in the State of Alaska. The team will:

  • Promote smart and environmentally sound floodplain management activities.
  • Increase and improve flood risk communication and outreach among local, tribal, state, and federal agencies.
  • Provide assistance in identifying and prioritizing actions to reduce the threat, vulnerability, and consequences of flooding in the State of Alaska.
  • Facilitate strategic planning and implementation of life-cycle mitigation, response and recovery actions to reduce the threat, vulnerability, and consequences of flooding in the State of Alaska.
  • Create or supplement a process or processes to collaboratively identify floodplain management issues and implement or recommend solutions.
  • Identify and implement ways to leverage available resource and information between agencies.
  • Increase and improve flood risk communication and outreach.
  • Promote wise stewardship of the taxpayers' investments.
  • Develop more comprehensive state flood risk management policies and strategies.
  • Develop advanced hydrologic predictive services to reduce loss of life and property damage from flooding.
Team Activities

Ice Jam Training and Freeze-up Investigations (FY21)

The Alaska District in cooperation with CRREL, DCRA, NWS, Alaska Railroad and Municipality of Anchorage plans to provide ice jam related training to local partners to inform them on ice mechanics, ice jam terminology, ice jam database information and mitigation strategies with a focus on non-structural solutions. Development of a Technical Report is also being pursued to summarize climate information coincident with the jams identified for further analysis and statistical correlations.

Improving Access to Relative Sea Level Change (RSLC) Guidance in Alaska (FY20)

This interagency project would provide access to relative sea level change (RSLC) estimates and guidance for RSLC approximations in Alaska to address challenges associated with incorporating RSLC into flood risk reduction studies in a region with limited data. The RSLC guidance document is currently under development.

Kotlik Coastal Flood Awareness and Outreach (FY19)

The Alaska District in cooperation with DGGS, DCRA, DHS&EM, and the Native Village of Kotlik seeks to conduct coastal flood awareness, outreach, and data collection activities at Kotlik, Alaska by developing flood risk materials, collecting short-term water level data and meeting with the community to share information and improve risk communication. Water level monitors were set in Summer 2020.

Lowell Creek Emergency Action Plan and Table-Top Exercise (FY18)

This interagency project includes several Silver Jackets' partners who participated in a table-top exercise with the City of Seward in March 2019. An Emergency Action Plan was drafted for the Lowell Creek Tunnel with coordination between the City and the Silver Jackets' partners. The final draft was returned to the City in September 2020 for completion and submission for approval.
