42-32. Office & Institutional District (OI)

  1. Purpose. The purpose of the Office & Institutional District (OI) is to foster orderly growth where the principal use of land is a mixture of office, institutional, and residential. The intent of this district is to allow for office, institutional and residential development that: (1) is directed largely to Neighborhood Anchors as defined in the Comprehensive Plan; (2) is compatible with adjacent development and the surrounding community; and (3) will minimize congestion and sprawl.
  2. Density and Dimensional Requirements. Each use allowed in this district shall at a minimum conform to the following requirements (in the case of a nonresidential use the residential density requirements shall not apply). In some cases a specific use may be required to meet the Supplemental Requirements as set forth in §42-62 (Supplemental Requirements).
    Table 2.6. OI Density and Dimensional Requirements
    (1) Residential Density (units/acre) (2) Standard 4
    (3) Maximum 16
    Maximum Impervious Surface (%) 80
    (4) Yard Setbacks (feet) Front or ROW Local 15
    Collector 25
    Thoroughfare 35
    Boulevard 45
    Expressway 55
    Freeway 60
    Side 10
    Rear 10
    (5) Maximum Height (feet) 50
    1. Residential density shall be calculated utilizing the entire acreage of a tract of land. Under this scenario, residential density shall be determined based on the following formula:

      Lot size x allowable units per acre = permitted dwelling units
      The following example assumes a 5 acre tract with an allowable density of 4 units/acre:
      5 acres x 4 units per acre = 20 permitted dwelling units

      The maximum residential density for portions of the tract with a slope of 60 percent or greater (where such slope areas of the tract account for ten (10) percent or more of the tract) shall be one- half (½) the eligible density.

    2. Standard residential density shall be applied:
      1. On a lot existing at the time of the initial adoption of this Chapter, where there is not adequate area to comply with the applicable standard residential density requirement.
      2. To single-family residential uses.
    3. Maximum residential density shall be available to applicants proposing
      multifamily developments with three (3) or more units (specifically excluding
      single-family units) where:
      a. A total of at least five (5) units would be permitted by standard residential
      density, and
      b. Such dwellings shall be served by both: (1) a public water supply system
      and (2) a sewage disposal system (of the following types: municipal,
      approved public, or approved community)which meet the requirements of
      the local or State authorities having jurisdiction thereof.
    4. Accessory structures may be located in the side, rear or front yards and may be setback a minimum of five (5) feet from the side or rear property lines and ten (10) feet from the front or Right of Way (ROW).
    5. Conditional Rezoning Requirement. Developments proposing to have ten (10) or
      more multifamily dwellings shall apply as a conditional rezoning. Subdivisions proposing to cluster the dwelling units on fifty percent (50%) or less of the total project area used to calculate the allowed density, must apply as a conditional rezoning.
