GENERAL PROVISIONS
(A) This chapter’s protection standard is the regulatory flood.
(B) 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 county shall be as delineated on the 1% annual chance flood profiles in the Flood Insurance Study of Owen County, Indiana and Incorporated Areas and the corresponding Flood Insurance Rate Map dated March 3, 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 county, delineated as an “A Zone” on the Owen County, Indiana and Incorporated Areas Flood Insurance Rate Map dated March 3, 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 State 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 State Department of Natural Resources for review, 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 community’s known flood prone areas shall be according to the best data available as provided by the State 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.
(BC Ord. 2014-0004, passed 2- -2014)
(A) No structure shall hereafter be located, extended, converted or structurally altered within the SFHA without full compliance with the terms of this chapter and other applicable regulations.
(B) No land or stream within the SFHA shall hereafter be altered without full compliance with the terms of this chapter and other applicable regulations.
(BC Ord. 2014-0004, passed 2- -2014) Penalty, see § 153.999
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.
(BC Ord. 2014-0004, passed 2- -2014)
(A) 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.
(B) 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.
(C) 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.
(BC Ord. 2014-0004, passed 2- -2014)
In the interpretation and application of this chapter, all provisions shall be:
(A) Considered as minimum requirements;
(B) Liberally construed in favor of the governing body; and
(C) Deemed neither to limit nor repeal any other powers granted under state statutes.
(BC Ord. 2014-0004, passed 2- -2014)
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 the county, the State Department of Natural Resources or the state for any flood damage that results from reliance on this chapter or any administrative decision made lawfully thereunder.
