(A) Lands to which this chapter applies. This chapter shall apply to all SFHAs/FEHAs and known flood prone areas within the jurisdiction of Morgan County and the towns of Bethany, Brooklyn, and Paragon.
(B) Basis for establishing regulatory flood data. This chapter’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 Morgan County, the Town of Bethany, the Town of Brooklyn, and the Town of Paragon shall be as delineated on the 1% 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 Morgan County, the Town of Bethany, the Town of Brooklyn, and the Town of Paragon, 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, floodway, and fringe limits of any watercourse in the communities' 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.
(C) Basis for establishing fluvial erosion hazard map. The FEHAs shall be identified on the Indiana Silver Jacket Project Fluvial Erosion Hazard Regional Map of the Upper White Watershed for Morgan County dated March 25, 2014. The map was developed by the Indiana Fluvial Erosion Hazard (FEH) Mitigation Program. The refined corridor shows areas of potential lateral channel migration. These areas have been derived from predicted channel meander belt width. No assumptions are made or implied regarding when lateral channel migration might occur. It also is not implied that areas outside of the refined corridor will not experience lateral channel migration: only that there is a higher potential for erosion inside the refined corridor. Only streams with a drainage area of greater than two square miles have been mapped. This map is designed to be used at a maximum scale of 1:10,000. Use of this map at a high resolution may be misleading. Additional details about why and how this map was produced and it intended uses, are available at the (FEH) program web-site.
(D) Establishment of floodplain development permit. A floodplain development permit shall be required in conformance with the provisions of this chapter prior to the commencement of any development activities in areas of special flood hazard/fluvial erosion hazard.
(E) Compliance. No structure shall hereafter be located, extended, converted or structurally altered within the (SFHA)/(FEHA) without full compliance with the terms of this chapter and other applicable regulations. No land or stream within the (SFHA)/(FEHA) shall hereafter be altered without full compliance with the terms of this chapter and other applicable regulations.
(F) Abrogation and greater restrictions. This chapter is not intended to repeal, abrogate, or impair any existing easements, covenants, or deed restrictions. However, where this chapter and another conflict or overlap, whichever imposes the more stringent restrictions shall prevail.
(G) 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.
(3) If the elevation (natural grade) of the site in question is above the base flood elevation and not located within the floodway, that site shall be considered outside the SFHA and the floodplain regulations will not be applied. The property owner shall be advised to apply for a LOMA.
(H) Interpretation. In the interpretation and application of this chapter all provisions shall be:
(1) Considered as minimum requirements;
(2) Liberally construed in favor of the governing body; and
(3) Deemed neither to limit nor repeal any other powers granted under state statutes.
(I) Warning and disclaimer of liability. The degree of flood protection required by this chapter is considered reasonable for regulatory purposes and is based on available information derived from engineering and scientific methods of study. Larger floods can and will occur on rare occasions. Therefore, this chapter does not create any liability on the part of Morgan County, the Town of Bethany, the Town of Brooklyn, the Town of Paragon, the Indiana Department of Natural Resources, or the State of Indiana, for any flood damage that results from reliance on this chapter or any administrative decision made lawfully thereunder.
(J) Penalties for violation. Failure to obtain a floodplain development permit in the SFHA/FEHA or failure to comply with the requirements of a floodplain development permit or conditions of a variance shall be deemed to be a violation of this chapter. All violations shall be considered a common nuisance and be treated as such in accordance with the provisions of the Morgan County Zoning Ordinance as amended, and the penalty provisions thereof.
(1) A separate offense shall be deemed to occur for each day the violation continues to exist.
(2) The Floodplain Administrator shall inform the owner that any such violation is considered a willful act to increase flood damages and therefore may cause coverage by a Standard Flood Insurance Policy to be suspended.
(3) Nothing herein shall prevent the County or the towns from taking such other lawful action to prevent or remedy any violations. All costs connected therewith shall accrue to the person or persons responsible.
