This program involved a Cooperating Technical Partnership between FEMA, the Mifflin County GIS Department and Juniata College. The goal of the project was to update and improve the accuracy of the Digital Flood Insurance Rate (DFIRM) Maps for Mifflin County using a unique approach involving GIS (HEC-RAS). This project was completed early in 2006, and the updated DFIRMs were approved in August of 2006. Digital copies of the DFIRMs, as well as paper copies, are available in our office.
