90-Day Comment for Preliminary Floodplain Maps

90-Day Comment Period for Preliminary Floodplain Maps

The 90-Day Comment and Appeal Period for Granite County’s Preliminary Floodplain Maps and Study will run from March 11 – June 8, 2015.  

The Preliminary Maps and Study are part of a county-wide Digital Flood Insurance Rate Map project for Granite County initiated in 2011.  Montana DNRC managed the project with FEMA providing grant funding and project oversight. The project involved four new floodplain studies on portions of Flint, Frost, Camp, and Lower Willow Creeks.  The remaining existing mapped floodplains in the county were converted from paper format into digital format, and an updated Flood Insurance Study for Granite County was produced as part of the project.

Comments and Appeals on the preliminary maps and study can be submitted to the County or Towns by June 8, 2015 using the form provided. 

After June 8, 2015, the preliminary maps and study will be revised as necessary by DNRC and FEMA, based on submitted comments and appeals.  Once finalized, the maps and study will replace the existing 1982 Flood Insurance Rate Maps and Flood Insurance Study for Granite County that are currently in effect. Flood Insurance Rate Maps are used by the County and Towns to administer local floodplain regulations, and by lending institutions and insurance companies to identify flood risks for flood insurance requirements and premiums.   Once finalized, the new Flood Insurance Rate Maps and Flood Insurance Study for Granite County are expected to go into effect in spring 2016.

The County and Towns contacted affected landowners last fall and hosted public informational meetings on November 6, 2014 in Philipsburg and Hall to present the preliminary results of updated floodplain mapping.
