Eagle Mountain, UT Environmental Rules: Flood Zones (2026)

Chapter 15.105 EMMC applies to all areas of Eagle Mountain that may be flooded, per EMMC 15.105.020(A). The city notes in EMMC 15.105.020(B) that areas of special flood hazard have not been separately identified for Eagle Mountain and that water surface elevations have not been provided, so the city instead relies on the Flood Insurance Study for Utah County, dated June 19, 2020, and its accompanying Flood Insurance Rate Maps and Flood Boundary-Floodway Maps, adopted by reference as part of the chapter.

EMMC 15.105.020(C) requires a development permit, defined elsewhere in the chapter as the building permit issued under the city building code, before any construction can proceed in conformance with the chapter, and EMMC 15.105.020(D) bars any structure or land use change without full compliance with its terms. The city building official serves as floodplain administrator under EMMC 15.105.030(A), reviewing every building permit application to determine whether proposed construction, including manufactured home placement, will be reasonably safe from flooding, and confirming that any required federal or state permits, including Clean Water Act Section 404 approvals, have been obtained.

Enforcement is direct: EMMC 15.105.060 makes it unlawful to construct, locate, extend, convert, or alter any structure or land without complying with the chapter, classifies a violation as a misdemeanor, and sets a fine of not more than $1,000 or imprisonment of not more than 30 days, or both, for each violation, plus payment of the city's costs and expenses in the case. The city may also pursue any other lawful remedy to prevent or correct a violation.
