Additional Information

Mr. Chris Hanstad has over 15 years of focused experience in floodplain analysis and evaluation of projects for compliance with the National Flood Insurance Program (NFIP) regulations. As a Licensed Professional Engineer (IL, IN, and WI) and Certified Floodplain Manager he has led the Illinois Letter of Map Revision (LOMR) program for 8 years from its inception to make determination decisions for floodplain revision requests. Based on rigorous floodplain modeling technical standard and NFIP regulation compliance, Mr. Hanstad has personally made determination decisions for hundreds of LOMR applications which result in revisions to FEMA floodplain maps. Mr. Hanstad specializes in evaluating the flood risk impact of projects built in the floodplain on adjacent properties. He has made 7 floodway violation recommendations to FEMA and has provided litigation support for flooding resulting from a floodway violation. With in-depth knowledge of NFIP regulations and specialized technical skills, he is able to carefully bring together the necessary information and analysis to determine if a floodway violation has occurred and determine the impacts of the violation. Additionally, Mr. Hanstad performed flood simulation modeling to recreate observed flooding in order assess flood damage and losses. One of his strengths is his ability to translate complex technical information and present it in a clear and simple manner using maps and visual aids to communicate conclusive results.
