The purpose of this Article is to establish base density, intensity, and dimensional requirements for each standard zoning district.

1. Except where otherwise expressly stated, all lots and improvements within the Rural, Open Space and Residential standard zoning districts shall comply with the regulations prescribed in Figures 5.01(1) and (2), and all lots and improvements within non-residential standard zoning districts shall comply with the regulations prescribed in Figures 5.02(1) and (2).
2. Allowable yard setback adjustments, intrusions into required yards, and exceptions to maximum height are found in Sections 5.03 through 5.05. Substandard lots, nonconforming uses, nonconforming structures, and nonconforming sites legally created before establishment of these requirements are addressed in Article 15.

1. Limitations on Yard Setback Adjustments
   1. No yard shall be reduced in area or dimension so as to make such yard less than the minimum required by this Chapter. If an existing yard is less than the minimum required, it shall not be reduced further, except where exempted by the provisions of this Section.
   2. No required yard or lot area allocated to satisfy the minimum yard or lot area requirements for one building or structure shall be used to satisfy the minimum yard or lot area requirement for another building or structure.
2. Front Yard Setback and Corner Lot Street Side Yard Setback Adjustment
   The required front or street side yard setback for a principal structure may be reduced on any lot where more than 50 percent of the same-type principal structures on the same block face do not meet the required front yard or street side yard setback. In such instances, the required front yard or street side yard setback for the proposed structure shall be the average of all the same-type principal structures on the same block face.

The minimum setbacks listed in Figures 5.01(2), 5.02(2), and 5.03(2) establish the minimum required yards/setbacks in the associated zoning districts, except that the following intrusions by buildings and structures are permitted into the minimum required yards:

1. Permitted Intrusions into Required Front and Street Side Yards.
   1. Chimneys, flues, sills, pilasters, lintels, cornices, eaves, gutters, satellite dishes with a diameter of 20 inches or less, and other architectural and ornamental features attached to a building, provided they do not extend more than two and one-half feet into the required yard.
   2. Yard lights, ornamental lights, and nameplate signs, provided they comply with applicable exterior lighting requirements of Section 94.12.11.
   3. Terraces, steps, open walled porches, decks, stoops, or similar appurtenances to residential buildings that do not extend above the floor level of the adjacent building entrance, provided they do not locate closer than 20 feet to any front or street lot line.
   4. Fences, in accordance with Section 94.12.03.
   5. Lawn ornaments and flag poles, provided that in residential zoning districts flag poles do not exceed 35 feet in height and lawn ornaments do not exceed 6 feet in height, and that flag poles are constructed with footings that extend not less than 42 inches below the existing ground level unless secured in another manner verified by a structural engineer.
   6. Stormwater retention and detention ponds and stormwater related structures.
2. Permitted Intrusions into Required Interior Side Yards.
   1. Chimneys, flues, sills, pilasters, lintels, cornices, eaves, gutters, satellite dishes with a diameter of 20 inches or less, and other ornamental features attached to a building, provided they do not extend more than two and one-half feet into the required yard.
   2. Fences, in accordance with Section 94.12.03.
   3. Fire escapes that do not extend more than three feet into the required yard.
   4. Lawn ornaments and flag poles, provided that in residential zoning districts flag poles do not exceed 35 feet in height and all lawn ornaments do not exceed 6 feet in height, and that flag poles are constructed with footings that extend not less than 42 inches below the existing ground level unless secured in another manner verified by a structural engineer.
   5. Stormwater retention and detention ponds and stormwater related structures.
3. Permitted Intrusions into Required Rear Yards.
   1. Terraces, steps, uncovered porches, decks, stoops, or similar appurtenances to residential buildings, provided they do not locate closer than 20 feet to the rear lot line.
   2. Chimneys, flues, sills, pilasters, lintels, cornices, eaves, gutters, satellite dishes with a diameter of 20 inches or less, and other architectural and ornamental features attached to a building, provided they do not extend more than two and one-half feet into the minimum required yard.
   3. Fences, in accordance with Section 94.12.03.
   4. Fire escapes that do not extend more than three feet into the minimum required yard.
   5. Lawn ornaments, play sets, tree houses, trampolines, and flag poles, provided that in residential zoning districts flag poles do not exceed 35 feet in height and all other lawn ornaments do not exceed 6 feet in height, that flag poles are constructed with footings that extend not less than 42 inches below the existing ground level unless secured in another manner verified by a structural engineer, and that tree houses are not intended for human habitation.
   6. Stormwater retention and detention ponds and stormwater related structures.

1. Exceptions: The maximum building heights listed in Figures 5.01(2), 5.02(2), and 5.03(2) are the maximum permitted heights for all buildings and structures in the associated zoning districts, except for
   1. Church spires; belfries; cupolas and domes that do not contain useable space; public monuments; water towers; telecommunication towers; fire and hose towers; flag poles; and farm structures such as barns, silos, and grain elevators.

No interior side lot line setback for zero lot line structures. (c) Includes all gravel and hard surfaces as defined in Section 94.17.04. This setback does not apply to intrusions for driveway and pedestrian way entrances from street; driveways, pedestrian ways, and parking lots that are shared or provide cross-access between lots; or any land inside of a fenced yard area in an industrial district. (d) Front and street side yard setbacks for accessory structures as the same as the minimum front and street side setback for the principal structure.

1. Calculation Method. The method described in this Section shall be used to calculate the maximum permitted number of dwelling units on lands in the AR Agriculture and Residential district.
   1. Determine Parcel(s) to be used in Calculation. Determine whether calculation of maximum residential density will be based on a single parcel (e.g., a single ¼ ¼ section of land), or on all lands in contiguous common ownership. Generally, maximum density will be calculated on a parcel basis. However, when there is more than one common contiguous parcel, the applicant is encouraged to include all AR zoned lands in contiguous common ownership in the calculation.
   2. Measure Parcel/Ownership Area. Measure the “gross site area” of the individual parcel or contiguous common ownership lands, including all roads and navigable waters that are within the deed parcel.
   3. Incorporate Density Factor. Divide the gross site area by 20 and round up if any fractional amount is equal to ½ or greater. This is the total number of dwelling units that are permitted on the lands zoned AR, including preexisting dwellings and other preexisting principal uses.
   4. Small Parcels. Individual, legally created parcels that are less than 20 acres in gross site area in the AR district shall be allowed a total of one dwelling unit. No further residential dwelling units or principal land uses shall be permitted while the land remains under AR zoning on individual parcels less than 20 acres.
   5. Figure 5.03 shows one of several possible approaches of how the total of 4 dwelling units might be constructed on an 80-acre example contiguous common ownership tract zoned AR.
   
   Figure 5.03: Example of “1 per 20” Density in AR Zoning District

2. Demarcation on Official Zoning Map. Upon the date of the first permit for a residential dwelling unit or other principal use under the provisions of this Section, the Zoning Administrator shall mark the associated parcel or set of contiguous common ownership lands as AR-C (with the “C” representing cluster) on the Official Zoning Map. The Zoning Administrator shall keep track of the total number of dwelling units or other principal uses created and remaining on each parcel or set of contiguous common ownership lands from the date of that first permit and may also mark remaining dwelling units for each parcel or set of contiguous common ownership lands on the Official Zoning Map. All additional dwelling units or other principal uses following that initial date shall conform to the maximum density calculated for the parcel or contiguous common ownership lands as such lands were sized and configured on that initial date.
3. Recorded Document Required. In conjunction with the division of the first residential lot or permitting of the first new residence on a parcel in the AR zoning district, the landowner must record a document in the Marathon County Register of Deeds Office reflecting how the allotted number of dwelling units are to be allocated among the affected parcels. This shall be done prior to the recording of any land division, and in a form approved by the Zoning Administrator. Subsequent modifications to any such recorded document, changing the allotment or assignment of principal uses or otherwise, shall be permitted only upon advance written authorization of the Zoning Administrator. The land owner shall then record a new or amended document showing the modifications.
