Construction in the Floodplain

Blaine County has specific requirements for all construction within the floodplain. Fill in the floodplain in highly discouraged and most often prohibited. In unique circumstances, fill may be approved but only with a balanced cut and fill approach. 

All residential structures must be elevated above the base flood elevation. The most common foundation type is a vented crawlspace, as illustrated below. Please contact us (208) 788-5570 for more specific information about constructing in flood prone areas.
