According to FEMA mapping from 2013, the area that contains World’s Fair Park would be theoretically inundated with 11-Feet of flood waters under the 500-Year Flood event. But something about the mapping just did not “feel” right. After extensive review of both the lay of the land, and comparing this with the 2013 model results, it was clear that something was wrong in the model. In fact, the model showed a downstream obstruction to overland flow that was not there. CCI evaluated the existing FEMA Flood Insurance Map (FIRM) and HEC-RAS model. The results of this study speaks for itself.
