Silver Jackets: Addressing Flooding in North Dakota - A Case Study

This showcase discusses the interagency collaboration between the North Dakota Silver Jackets program, highlighting the importance of identifying flood risks, available resources, and lead agencies. The case study focuses on the James River, examining the need for data, such as LiDAR terrain information and bridge surveys, to understand baseline flood conditions and develop effective solutions. This collaborative approach ensures a unified understanding of the problem and commitment to resolving flooding issues.

Has the full risk been identified? • What are the baseline conditions for flooding? • Who is affected by the flooding (urban areas, rural areas, critical facilities)? • What resources are available? • What technical data is available? • Which agency has the best authority to fit these needs? • What if we put on our Silver Jacket!!
