LDC 6.13.5 Flood plain and protection
CODE states: A. This section provides requirements for all land use activities, including single family residences, which materially change the location, elevation, size, capacity, or hydraulic characteristics of the existing one percent (100-year) flood plain as identified by the Federal Emergency Management Agency (FEMA). The intent is to ensure that equivalent flood plain volume and conveyance is maintained. This section also supplements Division 5.3 Flood Plain Overlay Zone. B. Land use activities which materially change the flood plain may be permitted when calculations performed by a licensed professional are provided demonstrating that compensating storage or other hydraulic characteristics are provided on the owner's property or within an easement. The calculations shall be reviewed and approved by the County Engineer or his designee. C. Land use activities that do not meet the thresholds for a stormwater analysis shall minimally be required to demonstrate one-for-one compensating storage, to be reviewed and approved by the County Engineer or his designee. D. When proposed improvements associated with mass grading plans, major site plans or improvement plans encroach into a flood hazard zone, it shall be necessary for the applicant to file a map amendment or revision with FEMA.
APPLICANT request - There are three (3) different flood plains on site; two (2) are Marion County Flood Prone Areas and one (1) is a FEMA Flood Zone. The elevation difference between the FEMA Flood Zone and the Marion County Flood Prone Area for Lake Kerr is 0.61 inches, with the FEMA Flood Zone being the higher elevation. We are proposing the FF elevation of the proposed building to be 2.75 inches, one foot above the FEMA BFE, and to not have to provide floodplain compensation for the fill in the FEMA flood plain of Lake Kerr (~5,000 acres) due to it being de minimis. We would also like to request not providing any flood plain compensation for the southern Marion County Flood Prone area located onsite, as it does not have an established BFE and based on the owner not seeing any flooding conditions nor standing water onsite since family ownership dating back to the early 1970s.
