Full Breakdown
Hemet's floodplain management article applies to all FEMA-designated special flood hazard areas within city limits, based on the Flood Insurance Study and FIRMs dated September 28, 1990. A development permit from the floodplain administrator (the city engineer) is required before any construction, fill, or alteration begins in these areas. New and substantially improved structures must have their lowest floor elevated to or above the base flood elevation, or be floodproofed for non-residential buildings, with elevation certified by a registered engineer or surveyor. Encroachments within a designated floodway, including fill and new construction, are prohibited unless an engineer certifies no increase in base flood elevation will result. Appeals go to the city council.
Violations & Fines
Constructing, altering, or filling land in a special flood hazard area without the required development permit, or violating elevation and floodproofing conditions, is a misdemeanor under Sec. 14-238; the city council may take further lawful action to remedy the violation.
