Sec. 13-2-60 General Applicability of Nonconforming Use Status.
   (a)   Applicability. If these standards in this Article conform with Sec. 87.30, Wis. Stats., NR 116, Wis. Adm. Code, and 44 CFR 59-72, for cities and villages, they shall apply to all modifications or additions to any nonconforming use or structure and to the use of any structure or premises which was lawful before the passage of this Chapter or any amendment thereto.
   (b)   Existing Lawful Use of a Structure. The existing lawful use of a structure or its accessory use which is not in conformity with the provisions of this Chapter may continue subject to the following conditions:
      (1)   No modifications or additions to a nonconforming use or structure shall be permitted unless they comply with this Chapter. The words "modification" and "addition" include, but are not limited to, any alteration, addition, modification, structural repair, rebuilding or replacement of any such existing use, structure or accessory structure or use. Maintenance is not considered a modification; this includes painting, decorating, paneling and other nonstructural components and the maintenance, repair or replacement of existing private sewage or water supply systems or connections to public utilities. Any costs associated with the repair of a damaged structure are not considered maintenance.
      (2)   The construction of a deck that does not exceed two hundred (200) square feet and that is adjacent to the exterior wall of a principal structure is not an extension, modification or addition. The roof of the structure may extend over a portion of the deck in order to provide safe ingress and egress to the principal structure.
      (3)   If a nonconforming use or the use of a nonconforming structure is discontinued for twelve (12) consecutive months, it is no longer permitted and any future use of the property, and any structure or building thereon, shall conform to the applicable requirements of this Chapter;
      (4)   The Village of Edgar shall keep a record which lists all nonconforming uses and nonconforming structures, their present equalized assessed value, the cost of all modifications or additions which have been permitted, and the percentage of the structure's total current value those modifications represent;
      (5)   No modification or addition to any nonconforming structure or any structure with a nonconforming use, which over the life of the structure would equal or exceed fifty percent (50%) of its present equalized assessed value, shall be allowed unless the entire structure is permanently changed to a conforming structure with a conforming use in compliance with the applicable requirements of this Chapter. Contiguous dry land access must be provided for residential and commercial uses in compliance with Section 13-2-42(b). The costs of elevating a nonconforming building or a building with a nonconforming use to the flood protection elevation are excluded from the fifty percent (50%) provisions of this Subsection;
      (6)   No maintenance to any nonconforming structure or any structure with a nonconform- ing use, the cost of which would equal or exceed fifty percent (50%) of its present equalized assessed value, shall be allowed unless the entire structure is permanently changed to a conforming structure with a conforming use in compliance with the applicable requirements of this Chapter. Contiguous dry land access must be provided for residential and commercial uses in compliance with Section 13-2-42(b).
      (7)   If on a per-event basis the total value of the work being done under Subsections (b)(6)-(7) equals or exceeds fifty percent (50%) of the present equalized assessed value, the work shall not be permitted unless the entire structure is permanently changed to a conforming structure with a conforming use in compliance with the applicable requirements of this Chapter. Contiguous dry land access must be provided for residential and commercial uses in compliance with Section 13-2-42(b).
      (8)   Except as provided in Subsection (b)(9) below, if any nonconforming structure or any structure with a nonconforming use is destroyed or is substantially damaged, it cannot be replaced, reconstructed or rebuilt unless the use and the structure meet this Chapter's requirements. A structure is considered substantially damaged if the total cost to restore the structure to its pre-damaged condition equals or exceeds fifty percent (50%) of the structure's present equalized assessed value.
      (9)   For nonconforming buildings that are substantially damaged or destroyed by a nonflood disaster, the repair or reconstruction of any such nonconforming building shall be permitted in order to restore it to the size and use in effect prior to the damage event, provided that the minimum federal code requirements below are met and all required permits have been granted prior to the start of construction:
         a.   Residential structures:
            1.   Shall have the lowest floor, including basement, elevated to or above the base flood elevation using fill, pilings, columns, posts or perimeter walls. Perimeter walls must meet the requirements of Section 13-2-75(b).
            2.   Shall be anchored to prevent flotation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyance and shall be constructed with methods and materials resistant to flood damage.
            3.   Shall be constructed with electrical, heating, ventilation, plumbing and air conditioning equipment and other service facilities that are designed and/or elevated so as to prevent water from entering or accumulating within the components during conditions of flooding.
            4.   In A Zones, obtain, review and utilize any flood data available from a federal, state or other source.
            5.   In AO Zones with no elevations specified, shall have the lowest floor, including basement, meet the standards in Section 13-2-52(a).
            6. In AO Zones, shall have adequate drainage paths around structures on slopes to guide floodwaters around and away from the structure.
         b.   Nonresidential structures:
            1.   Shall meet the requirements of Subsection (b)(9)a.
            2.   Shall either have the lowest flowest floor, including basement, elevated to or above the regional flood elevation, or, together with attendant utility and sanitary facilities, shall meet the standards in Section 13-2-74(a) or (b).
            3.   In AO Zones with no elevations specified, shall have the lowest floor, including basement, meet the standards in Section 13-2-52(a).
      (10)   A nonconforming historic structure may be altered if the alteration will not preclude the structure's continued designation as a historic structure, the alteration will comply with Section 13-2-32(a), flood resistant materials are used, and construction practices and floodproofing methods that comply with Section 13-2-74 are used. Repair or rehabilitation of historic structures shall be exempt from the development standards of Subsection (b)(9)a above if it is determined that the proposed repair or rehabil- itation will not preclude the structure's continued designation as a historic structure and is the minimum necessary to preserve the historic character and design of the structure.
