Boundary County Flood Mitigation Plan 

In 2003, Boundary County adopted the Boundary County Flood Mitigation Plan. This plan was used as a resource in the All Hazard Mitigation process.  The following information was derived from the flood mitigation plan.

The LEPC identified the following as highly vulnerable to flood:

·         Neighborhoods:  The Bonners Ferry downtown area including Bonners Ferry City Hall, Kootenai River Inn and Kootenai Tribal headquarters.

·         Critical Facilities:  Boundary County Sheriff (911 Center and correction facility) and Courthouse.

·         Critical Transportation: Burlington Northern Railroad; US Highway 95 is the primary all weather road crossing for the Kootenai River in Bonners Ferry.

Flooding has historically taken its toll on the county’s road system.  Storm water issues are a high concern.  In 2003, Boundary County completed a county road inventory that was intended to be used as a planning tool for taking actions to improve the county’s storm water system and protect the county’s road system.

Boundary County and the municipalities within the county have spent approximately $10,552,000 to provide emergency and protective work and to repair public roads, water control systems, buildings and equipment, public utility systems and other public facilities due to flooding and landslide events.

Weather and long-term climate forecasting can help foresee the likelihood of unusual precipitation patterns and temperature regimes.  For this reason, the Boundary County Local Emergency Planning Committee has worked with Boundary County to secure two weather stations and two stream gauges on the county’s most flood-prone tributary, Myrtle Creek.

The City of Bonners Ferry has installed turbidity monitors that will monitor the Myrtle Creek watershed.  If a high level of sediment is detected then action can be taken.

The Kootenai National Wildlife Refuge has a weather monitoring station with a camera. This weather and camera is real-time and can be viewed via the internet.
