Section B. Basis for Establishing Regulatory Flood Data. This ordinance's protection standard is the regulatory flood. The best available regulatory flood data is listed below. (1) The regulatory flood elevation, floodway, and fringe limits for the studied SFHAs within the jurisdiction of the Town of Mooresville shall be as delineated on the one-percent annual chance flood profiles in the Flood Insurance Study of Morgan County, Indiana and Incorporated Areas and the corresponding Flood Insurance Rate Map dated October 2, 2014 as well as any future updates, amendments, or revisions, prepared by the Federal Emergency Management Agency with the most recent date. (2) The regulatory flood elevation, floodway, and fringe limits for each of the SFHAs within the jurisdiction of the Town of Mooresville, delineated as an "A Zone" on the Morgan County, Indiana and Incorporated Areas Flood Insurance Rate Map dated October 2, 2014 as well as any future updates, amendments, or revisions, prepared by the Federal Emergency Management Agency with the most recent date, shall be according to the best data available as provided by the Indiana Department of Natural Resources; provided the upstream drainage area from the subject site is greater than one square mile. Whenever a party disagrees with the best available data, the party needs to replace existing data with better data that meets current engineering standards. To be considered, this data must be submitted to the Indiana Department of Natural Resources for review and subsequently approved. (3) In the absence of a published FEMA map, or absence of identification on a FEMA map, the regulatory flood elevation, fioodway, and fringe limits of any watercourse in the community's known flood prone areas shall be according to the best data available as provided by the Indiana Department of Natural Resources; provided the upstream drainage area from the subject site is greater than one square mile. (4) Upon issuance of a Letter of Final Determination (LFD), any more restrictive data in the new (not yet effective) mapping/study shall be utilized for permitting and construction (development) purposes, replacing all previously effective less restrictive flood hazard data provided by FEMA. Section C. Establishment of Floodplain Development Permit. A Floodplain Development Permit shall be required in conformance with the provisions of this ordinance prior to the commencement of any development activities in areas of special flood hazard. Section D. Compliance. No structure shall hereafter be located, extended, converted or structurally altered within the SFHA without full compliance with the terms of this ordinance and other applicable regulations. No land or stream within the SFHA shall hereafter be altered without full compliance with the terms of this ordinance and other applicable regulations. Section E. Abrogation and Greater Restrictions. This ordinance is not intended to repeal, abrogate, or impair any existing easements, covenants, or deed restrictions. However, where this ordinance and another conflict or overlap, whichever imposes the more stringent restrictions shall prevail. Section F. Discrepancy between Mapped Floodplain and Actual Ground Elevations. (1) In cases where there is a discrepancy between the mapped floodplain (SFHA) on the FIRM and the actual ground elevations, the elevation provided on the profiles shall govern. (2) If the elevation of the site in question is below the base flood elevation, that site shall be included in the SFHA and regulated accordingly. Page ( 8
