(a) Areas To Be Regulated. This ordinance regulates all areas that would be covered by the regional flood or base flood as shown on the Flood Insurance Rate Map (FIRM) or other
maps approved by DNR. Base flood elevations are derived from the flood profiles in the Flood Insurance Study (FIS) and are shown as AB, Al-30, and AH Zones on the FIRM. Other regulatory zones are displayed as A and AO zones. Regional Flood Elevations (RFE) may be derived from other studies. If more than one map or revision is referenced, the most restrictive information shall apply.
(b) Official Maps and Revisions.
(1) The boundaries of all floodplain districts are designated as A, AB, AH, AO or Al-30 on the maps based on the Flood Insurance Study (FIS) listed below. Any change to the base flood elevations (BFE) or any changes to the boundaries of the floodplain or floodway in the FIS or on the Flood Insurance Rate Map (FIRM) must be reviewed and approved by the DNR and FEMA through the Letter of Map Change process (see Sections 13-2-80 and 13-2-81) before it is effective. No changes to RFEs on non- FEMA maps shall be effective until approved by the DNR. These maps and revisions are on file in the office of the Villag of Edgar Administrator. If more than one (I) map or revision is referenced, the most restrictive information shall apply.
(2) The pertinent floodplain zoning maps and flood insurance studies shall be (approved by FEMA and the DNR):
a. Flood Insurance Rate Map (FIRM), panel numbers 55073C02340F and 55073C02350F (Marathon), dated 7/22/2010; with corresponding profiles that are based on the Flood Insurance Study (FIS) dated 7/22/2010, volume #55073CV000A.
(3) These maps have been approved by the Wisconsin Department of Natural Resources and the Federal Emergency Management Agency (FEMA) and is on file wi the Village of Edgar Administrator.
(c) Establishment of Floodplain Zoning Districts. The regional floodplain areas are divided into three (3) districts as follows:
(1) The Floodway District (FW) is the channel of a river or stream and those portions of the floodplain adjoining the channel required to carry the regional floodwaters and are contained within AE Zones on the FIRM.
(2) The Floodfringe District (FF) is that portion of the floodplain between the regional flood limits and the floodway and displayed as AB Zones on the FIRM.
(3) The General Floodplain District (GFP) is those areas that have been or may be covered by floodwater during the regional flood and does not have a BFE or floodway boundary determined, including A, AH and AO zones on the FIRM.
(d) Locating Floodplain Boundaries. Discrepancies between boundaries on the official floodplain zoning map and actual field conditions shall be resolved using the criteria in Subsections (d)(I) and (2) below. If a significant difference exists, the map shall be amended according to Secs. 13-2-80 and 13-2-81. The Zoning Administrator can rely on a boundary derived from a profile elevation to grant or deny a land use permit, whether or not a map amendment is required. The Zoning Administrator shall be responsible for documenting actual pre-development field conditions and the basis upon which the district boundary was determined and for initiating any map amendments required under this Section. Disputes between the Zoning Administrator and an applicant over the district's boundary line shall be settled according to Sec. 13-2-53 and the criteria in Subsection (d)(l) and (2) below. Where the flood profiles are based on established base flood elevations from a FIRM, FEMA must approve any map amendment or revision pursuant to Sections 13-2-80 and 13-2-81.
(1) If flood profiles exist, the map scale and the profile elevations shall determine the district boundary. The regional or base flood elevations shall govern if there are any discrepancies.
(2) Where flood profiles do not exist, the location of the boundary shall be determined by the map scale.
[Note: Where the flood profiles are based on established base flood elevations from a FIRM, FEMA must also approve any map amendment pursuant to Sec. 13-2-80(f)].
(e) Removal of Lands From Floodplain. Compliance with the provisions of this Chapter shall not be grounds for removing land from the floodplain unless it is filled at least two (2) feet above the regional or base flood elevation, the fill is contiguous to land outside the floodplain, and the map is amended pursuant to Secs. 13-2-80 and 13-2-81.
[Note: This procedure does not remove the requirements for the mandatory purchase of flood insurance. The property owner must contact FEMA to request a Letter of Map Change (LOMC).
(f) Compliance. Any development or use within the areas regulated by this Chapter shall be in compliance with the terms of this Chapter, and other applicable local, state and federal regulations.
(g) Municipalities and State Agencies Regulated. Unless specifically exempted by law, all cities, villages, towns and counties are required to comply with this Chapter and obtain necessary permits. State agencies are required to comply if Sec. 13.48(13), Wis. Stats., applies. The construction, reconstruction, maintenance and repair of state highways and bridges by the Wisconsin Department of Transportation is exempt when Sec. 30.2022, Wis. Stats., applies.
(h) Abrogation and Greater Restrictions.
(1) This Chapter supercedes all the provisions of any zoning ordinance enacted under Section 61.35, Wis. Stats., for villages, Sec. 62.23, Wis. Stats., for cities, or Sec. 87.30, Wis. Stats., which relate to floodplains. A more restrictive ordinance than this Chapter shall continue in full force and effect to the extent of the greater restrictions, but not otherwise.
(2) This Chapter is not intended to repeal, abrogate or impair any existing deed restrictions, covenants or easements. If this Chapter imposes greater restrictions, the provisions of this Chapter shall prevail.
(i) Interpretation. In their interpretation and application, the provisions of this Chapter are the minimum requirements liberally construed in favor of the governing body and are not a limitation on or repeal of any other powers granted by the Wisconsin Statutes. If a provision of this Chapter, required by NR 116, Wis. Adm. Code, is unclear, the provisions shall be interpreted in light of the standards in effect on the date of the adoption of this Chapter or in effect on the date of the most recent text amendment to this Chapter.
(j) Warning and Disclaimer of Liability. The flood protection standards in this Chapter are based on engineering experience and scientific research. Larger floods may occur or the flood height may be increased by man-made or natural causes. This Chapter does not imply or guarantee that non-floodplain areas or permitted floodplain uses will be free from flooding and flood damages. This Chapter does not create liability on the part of, or a cause of action against, the Village of Edgar or any officer or employee thereof for any flood damage that may result from reliance on this Chapter.
(k) Severability. Should any portion of this Chapter be declared unconstitutional or invalid by a court of competent jurisdiction, the remainder of this Chapter shall not be affected.
(I) Annexed Areas for Cities and Villages. The Marathon County floodplain zoning provisions in effect on the date of annexation shall remain in effect and shall be enforced by the municipality for all annexed areas until the Village of Edgar adopts and enforces an ordinance which meets the requirements of NR 116, Wis. Adm. Code, and the National Flood Insurance Program (NFIP). These annexed lands are described on the Village of Edgar's official zoning map. County floodplain zoning provisions are incorporated by reference for the purpose of administering this Section and are on file in the office of the Village of Administrator. All plats or maps of annexation shall show the regional flood elevation and the location of the floodway.
