(a) Conformity with Master Plan. The proposed development shall conform to the City's Master Plan.
(b) Planned Residential Building Groups or Projects.
(1) Spacing and orientation of residential developments. Spacing between buildings and orientation in residential building groups shall be as follows:
A. In buildings containing multiple dwelling units, walls containing main window exposures or main entrances, shall be so oriented as to insure adequate light and air exposures.
B. Such buildings shall be so arranged as to avoid undue exposure to concentrated loading or parking facilities, and shall be so oriented as to preserve visual and audible privacy between adjacent buildings.
C. A building wall exposing both windows and entrance way shall be located no closer to another building than a distance equal to the height of the taller building of the two, but in no case less than fifty feet.
D. A building wall exposing only windows or only an entrance way shall be located no closer to another building than a distance equal to the height of the taller building of the two, but in no case less than thirty-five feet.
E. A building group may not be so arranged that any temporary or permanently inhabited building is inaccessible by emergency vehicles.
(2) Recreation and play areas. In residential building groups providing for permanent family occupancy there shall be provided at the time of development, active play areas for children and other leisure time recreation areas in safe locations, and in an amount equal to not less than ten percent (10%) of the gross land area of the development.
(3) Vehicle and pedestrian circulation. Adequate provision for vehicle and pedestrian circulation shall be provided as follows:
A. Safe and convenient arrangement of walks, roadways, driveways and off-street parking and loading space.
B. Separation of general vehicle traffic from pedestrian walks and public transportation loading places.
(4) Paving and drainage. The developer shall install throughout any proposed residential building group or project, hard-surfaced streets at reasonable grades, which shall include curbs or gutters, catch basins and storm sewers.
(c) Planned Commercial and Manufacturing Building Groups or Projects.
(1) Spacing and orientation of commercial and manufacturing buildings. Spacing between buildings and orientation in commercial and industrial building groups shall be as follows:
A. Exterior walls of opposite buildings shall be located no closer than a distance equal to the height of the taller building.
B. A building group may not be so arranged that any permanently or temporarily inhabited building is inaccessible by emergency vehicles.
(2) Signs and lighting. All signs and lighting devices shall be of a type and design that will not conflict with traffic control signs and lights, and shall be oriented so that they will not produce glare on the roadway or adjacent residential development.
(3) Planting and screening. In business building groups abutting or within 100 feet of residential districts, fences, walls or year-round screen planting shall be required when deemed necessary to shield adjacent residential districts from parking lot illumination, headlights, fences, heat, blowing papers and dust, and to reduce the visual encroachments of commercial architecture, signs and activity.
(d) Justification for Exception. Such exceptions which may be required from the strict application of the Zoning Ordinance shall be solely for the purpose of promoting an integrated site plan no less beneficial to the residents or occupants of such developments as well as of neighboring properties than would be obtained under the normal requirements of the Zoning Ordinance.
