The floodplain zoning ordinance shall establish administrative procedures for obtaining all required permits, special exceptions, conditional uses, variances, appeals and amendments. These procedures shall provide for the following: (a) An application shall be made to the zoning administrator for all zoning permits, special exceptions, conditional uses, variances and amendments. The application shall include, but not be limited to, the following information:1. The name and address of the applicant and property owner;2. The legal description of the property and the type of proposed use;3. A map plan which accurately locates or describes the proposal with respect to the floodway and floodplain, and which provides all pertinent information such as the fill dimensions and elevations, building floor elevations, and floodproofing data; and4. For all subdivision proposals, as defined in s. 236.02(8), Stats., and for other land divisions or proposed developments which have a total area that exceeds 5 acres or which have an estimated cost that exceeds $125,000, the applicant shall provide all of the computations which are required to show the effect of the proposal on flood heights, velocities and floodplain storage. The municipality may transmit this data to the department for review. For the purpose of this paragraph, the cost of the proposal shall be estimated to include all structural development and landscaping improvements such as access and road development, electrical and plumbing services development, and other similar items, which can be reasonably applied to the overall development costs, but may not include the cost of the land.(b) For land divisions and proposed developments which do not exceed 5 acres in area and which have an estimated cost of $125,000 or less, if the regional flood profile has not been determined and the conditions in par. (a) 4. are not present, the municipality may transmit the information required in par. (a) 1. to 3. to the department for a determination of flood protection elevations and for an evaluation of the effects of the proposal upon flood heights, velocities and floodplain storage. Additional information, such as valley cross sections or survey data, may be required by the department when needed to determine the effects of the proposal; this information shall then be obtained from the applicant by the municipality. The department shall advise the municipality of its findings within 30 days after receiving the data, or within 30 days after receiving all requested additional information. Failure of the department to respond within 30 days shall be construed to mean it has no comment.(c) Public hearings shall be held by municipalities on all special exceptions, conditional uses, variances, appeals and amendments. Proper notice shall be given of such public hearings in accordance with appropriate statutes; mailed notice of such public hearings and a copy of the application shall be given to the appropriate department district office. Such notice shall specify the time and place of the hearing and give sufficient details concerning the subject matter of the public hearing.(d) A copy of all decisions granting or denying a special exception, conditional use, variance or amendment to the floodplain zoning ordinance shall be mailed within 10 days to the appropriate department district office.(3) CERTIFICATE OF COMPLIANCE. No vacant land in the floodplain, and no building hereafter erected, altered or moved into the floodplain, may be occupied or used until the applicant obtains a certificate of compliance from the municipality.

Each floodplain zoning ordinance shall include a separate section establishing appropriate penalties for violations of various provisions of the ordinance. An appropriate penalty, as reflected in s. 87.30(2), Stats., may include an injunction for abatement or removal, and a fine or forfeiture. Any violation of the provisions of the floodplain zoning ordinance shall be investigated and reported to the appropriate municipal attorney, corporation counsel or district attorney for the prosecution of the violator.(5) PUBLIC INFORMATION. (a) Where useful, marks on bridges or buildings or other markers may be set to show the depth of inundation during the regional flood at appropriate locations within the floodplain.(b) All available information in the form of maps, engineering data and regulations shall be readily available and should be widely distributed.(c) All legal descriptions of property in the floodplain should include information relative to the floodplain zoning classification when such property is transferred.Wis.
