Summary
Rose Hill requires new construction and substantial improvements in its Special Flood Hazard Areas to elevate both living space and mechanical equipment above the Regulatory Flood Protection Elevation, a standard built to keep homes and HVAC, electrical, and plumbing systems above storm-driven flood surges. The rule sits in § 150.40 and § 150.41 of the flood damage prevention chapter.
(4) All new electrical, heating, ventilation, plumbing, air conditioning equipment, and other service equipment shall be located at or above the RFPE or designed and installed to prevent water from entering or accumulating within the components during the occurrence of the base flood. These include, but are not limited to, HVAC equipment, water softener units, bath/kitchen fixtures, ductwork, electric/gas meter panels/boxes, utility/cable boxes, hot water heaters, and electric outlets/switches. ... (1) Residential construction. New construction and substantial improvement of any residential structure (including manufactured homes) shall have the reference level, including basement, elevated no lower than the regulatory flood protection elevation, as defined in § 150.05.
Full Breakdown
Two linked sections of Chapter 150 set Rose Hill's elevation-for-storms standard. 40(A)(4) requires all new electrical, heating, ventilation, plumbing, air conditioning, and other service equipment to sit at or above the Regulatory Flood Protection Elevation (RFPE), or be designed and installed so water cannot enter or accumulate in the components during a base flood. The list is specific: HVAC equipment, water softener units, bath and kitchen fixtures, ductwork, electric and gas meter panels and boxes, utility and cable boxes, hot water heaters, and electric outlets and switches all have to clear that line, whether installed new or as a replacement tied to a substantial improvement.
05, the mapped Base Flood Elevation plus two feet of freeboard. Together the two sections mean a house rebuilt after storm damage in Rose Hill's flood plain has to come back up on both fronts: the living floor and the mechanical systems that keep it running. 41(B)(2): floodproofing to the RFPE in lieu of elevation, provided the structure is watertight below that line.
Violations & Fines
Rebuilding or improving a structure in a Special Flood Hazard Area without elevating the reference level or the service equipment to the Regulatory Flood Protection Elevation is a Class 1 misdemeanor under § 150.99, carrying a fine of up to $100, up to 30 days in jail, or both, with each day of continued noncompliance a separate offense. A structure missing an elevation certificate is presumed in violation until documentation is filed.
