42-32. Office & Institutional District (OI)
- 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.
- 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 - 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 unitsThe 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.
- Standard residential density shall be applied:
- 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.
- To single-family residential uses.
- 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. - 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).
- 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.
- 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:
