Silver Bow Creek Floodplain Study Products


 

 Butte Silver Bow website header

Butte-Silver Bow County has been working with The Department of Environmental Quality (DEQ) and Pioneer Technical to complete the Silver Bow Creek/Streamside Tailings Superfund remediation project.  The cleanup, which consisted of removing six million yards of tailings (mine waste containing heavy metals) and related impacted soils from the floodplain of Silver Bow Creek, the reconstruction of the stream channel and floodplain, and re-vegetation of the affected area, has been completed.  As a result of this cleanup, a floodplain mapping revision is required.

When finalized, the new maps could have effects on some property owners in the mapped floodplain. If you are currently or will be shown in a 100-Year Floodplain, you can prepare for the eventual adoption of new Flood Insurance Rate Maps by taking the steps below.
