SEH assisted the City of Shoreview to obtain a flood hazard mitigation grant from the DNR to update the City’s FIRM. An updated HEC-HMS model was created to meet FEMA modeling standards. Modeling results were incorporated into the LOMR submittal to update existing BFEs. More than 200 properties were removed from floodplain zones based on the improved modeling and mapping.
