FEMA House Elevation



Lisle, IL 60532


Prairie Forge Group


Prairie Forge Group was retained by the Village of Lisle to design and engineer a FEMA-funded floodway project: engineering and designing the lifting of five residences. Groundwater, soil conditions, and underground utilities were studied. PFG conducted structural/geo-technical engineering investigations and reviewed findings. PFG then created design concepts identifying new structural foundations and elevated access ways, all of which required upgrades to meet current building codes. PFG then surveyed, analyzed, and developed solutions for raising the houses, thus moving the livable areas above the Base Flood Elevation (BFE). PFG oversaw bidding and construction to ensure the work was performed in accordance with design standards.
