*   For each bedroom in addition to three (3) bedrooms permitted, an additional area of three hundred square feet shall be added to the minimum floor area of twelve hundred (1,200) square feet.
(i)   Floor Area Ratio (FAR) times the land area (LA) equals the maximum total amount of floor area acceptable for the development:
      FAR x LA = Max. Floor Area.
(ii)   Open Space Ratio (OSR) times the land area (LA) equals the minimum amount of open space acceptable for development:
      OSR x LA = Min. Open Space.
(iii)   Livability Space Ratio (LSR) times the land area (LA) equals the minimum amount of livability space acceptable for the development:
      LSR x LA = Min. Livability Space.
(iv)   Parking Space Ratio (PSR) times the number of living units (LU) equals the minimum number of car parking spaces required for residents:
      PSR x LU = Min. Parking Spaces.
   (Ord. 02-40. Passed 8-15-02.)
(d)   In the R-3 Residential District the front, side and rear yard requirements do not refer to the spacing between buildings for a multiple family development for two or more buildings on the same lot. The minimum distance between any two buildings shall not be less than thirty-five feet (35').  Whenever the side yard of a multiple family development abuts onto a lot that is used or zoned for residential purposes, the minimum side yard width shall be forty feet (40').
(e)   Off street parking shall be permitted to occupy part of the required front yard after approval of the parking plan layout and driveways by the City Planning Commission. A greenbelt fifteen feet (15') wide shall be maintained between the edge of the parking lot and the street right-of-way line.
(f)   If a side yard abuts onto a lot used or zoned for residential purposes, the minimum yard setback shall be thirty feet (30') on the side abutting a residential lot or residential use.
(g)   Off-street loading and unloading and parking shall meet the requirements set forth in Sections 1145.18, 1145.19 and 1145.20.
(h)   A side yard setback of thirty feet (30') shall be required for all principal and accessory buildings abutting a lot used or zoned for residential purposes.
(i)   The City Planning Commission may waive the height restrictions as it applies to portions of the building or structure when the industrial process requires towers or masses to exceed the maximum height of the overall physical plant. Yard setbacks shall not be penetrated by these masses.
(j)   A twenty five foot (25') wide greenbelt, six feet (6') in height shall be provided wherever the front, side or rear yard abut onto a lot that is used or zoned for residential purposes.
(k)   Off-street parking shall be permitted in the side and rear yard setback. When parking is planned within the side or rear yard setback, the parking plan layout shall be reviewed and approved by the City Planning Commission.
