The Problem Mineral County has older floodplain maps that lacked the detail that a hydraulic analysis would provide.
The Solution Our team of floodplain engineers and spatial mapping technicians worked together to analyze the flooding sources of the Clark Fork River and its tributaries. We performed a hydraulic analysis and associated floodplain mapping as part of the larger Mineral County floodplain mapping project. This data is the basis for flood insurance rate maps and is a county-wide project administered by the state and federal governments.
The Benefit Mineral County administration, in cooperation with DNRC and FEMA, will use the floodplain mapping documents to communicate flooding risks to residents along the flooding sources. It will also be the basis for riverine floodplain development for the next 30-50 years. This flood insurance study will be a timely tool for the community and will also help protect the Clark Fork and Columbia River watersheds.
