Iowa Floodplain Mapping Program Update
When the devastating floods of 2008 occurred in Iowa, approximately half of the state had digital Flood Insurance Rate Maps (FIRMs), with many of those being pre-Map MOD vintage (i.e. paper maps). Following the 2008 floods, the Iowa Department of Natural Resources became a FEMA Cooperating Technical Partner (CTP). Iowa’s CTP program is an example of leveraging local, state, and federal resources to develop comprehensive flood hazard products to support local floodplain management and mitigation - along with statewide updating of regulatory Flood Insurance Rate Maps (FIRMs).
This presentation provides an update to the progress made with the remainder of the $15 million Community Development Block Grant (CDBG) and recent use of FEMA’s annual Cooperating Technical Partnership (CTP) Grant Program to complete the creation of countywide FIRMs for the entire State of Iowa. At the beginning of the Iowa Floodplain Mapping Program in 2009, the goal has been to complete all 99 countywide FIRMS, based on the statewide LiDAR coverage. The completion of this goal is now within the grasp of the Iowa DNR.
