Lehi City participates in the National Flood Insurance Program (NFIP) and enforces FEMA flood zone development standards. A floodplain development permit is required for any construction or land alteration in a Special Flood Hazard Area (SFHA). Lehi's flood information page identifies two flooding types: groundwater flooding (seasonal water table rise) and surface water flooding (runoff from heavy rain or snowmelt). The Dry Creek corridor is a significant flood hazard area. In 2024, new FEMA Flood Insurance Rate Maps were released affecting Lehi's floodplain boundaries. Development near stream beds requires State Engineer authorization under Utah Code §73-3-29. LOMA and LOMR processes are available for properties incorrectly mapped.
