(A) Purpose. Development standards for each district dictate the maximum permitted density, minimum lot size, minimum lot width and frontage, minimum yard setbacks, maximum height, minimum ground floor area and maximum lot coverage or intensity. These regulations for the zone districts of the city are shown on Table 4.2: Residential Districts Lot Standards and Table 4.3: Nonresidential Districts Lot Standards.
(B) Interpreting the lot standards tables. The following explanations of terms should be consulted when interpreting Table 4.2: Residential Districts Lot Standards and Table 4.3: Nonresidential Districts Lot Standards. For more information on the meaning of terms in this ordinance, see Chapter 11: Definitions.
(1) Minimum lot size. The smallest area established by this ordinance on which a use, structure or building may be located in a particular district;
(2) Minimum lot width. This refers to the minimum width a lot must have in order to be considered developable by this ordinance. The horizontal distance is measured between side lot lines at the building setback line;
(3) Minimum lot frontage. The horizontal length of a lot measured between side lot lines at the street right-of-way or private street easement. All sides of a lot that abut a street are considered frontage;
(4) Front setback. The minimum allowable distance between the street right-of-way line and the facade of a principal building or structure projected to the sides of the lot measured perpendicular to the front lot line. The front setback applies to all frontages of a lot facing a street or right-of-way. For residential districts the setback is based on the classification of the road on which the building is located. The three road designations (arterial, collector/local) are based on the Center Township Thoroughfare Plan;
(5) Side setback. The minimum distance between the structure or building and the side lot lines. However, for corner and through lots, a front setback shall be maintained for any frontage of a lot upon a street;
(6) Rear setback. The minimum distance between the structure or building and the rear lot line. For through lots, the rear of the structure facing a street shall meet front setback requirements;
(7) Agricultural adjacency setback (residential only). This setback line shall exist only on residential property that is adjacent to agricultural uses, and only along the portions of the property line that are directly adjacent to the agricultural uses. Plantings shall not occur within this setback;
(8) Maximum height. In all instances, the height of a structure shall be measured from adjacent grade level to the highest point of the structure, excluding the necessary appurtenances such as chimneys, church spires, steeples, clock or bell towers, cooling towers, elevator bulkheads, fire towers, penthouses, stacks, tanks, water towers, transmission towers or essential mechanical equipment not prohibited by other laws or further provisions of this ordinance. No accessory structure located in a residential zoning district may exceed the height of the principal structure on the property. Certain height exceptions are permitted according to the provisions of § 7.3;
(9) Maximum intensity (business and industrial only). Maximum intensity is shown as the highest permissible floor area ratio (FAR). This ratio is found by adding up the total floor area for all floors of the building and dividing that number by the total lot area;
(10) Maximum lot coverage. The maximum ground area of a lot that can be covered by principal and accessory structures or buildings (this includes all impervious surfaces). For the purposes of this ordinance, parking areas shall be included as a structure;
(11) Minimum total living area (residential only). The sum of all horizontal floor area, including each story, of a residential building, exclusive of garages, porches, unfinished basements, unfinished attics, decks or terraces;
(12) Required open space for subdivisions (residential only). The required amount of open space, measured as a percentage of net land area. Required open space must be usable; and
(13) Minimum ground floor area (residential only). The sum of the horizontal floor area required on the ground level of a residential building, exclusive of garages, porches, decks or terraces. A raised half story may be included in this total.
(C) Living area. Each single- and multifamily dwelling unit shall have separate and individual kitchen and bathroom facilities unless as specified in § 7.21(B).
(D) Lot standards table. Lot standards are listed in the following tables under each district heading. Provisions for parking, signs and landscaping are set forth in Chapter 7: Development Standards.
