(a) The density of a PUD District shall not exceed a maximum gross density of five dwelling units per acre unless a density bonus is awarded as specified in division (b) herein. In calculating density, the following areas shall first be excluded from the total area available for development:
(1) Any area within the 100-year flood plain.
(2) Land used by public utilities as easements for major facilities such as electric transmission lines, sewer lines, water mains or other similar lands which are not available to the owner because of such easement.
(3) For that portion of land area with slopes in excess of 25% grade (prior to grading), density shall be calculated at two units per acre.
(4) For that portion of land area covered by perennial bodies of water in excess of one acre density shall be calculated at 3.2 units per acre.
(5) After the total area available for development has been determined by the above procedure, 18% of the remaining area shall be subtracted from such total area for street right of way purposes. This percentage shall apply regardless of the land actually required for street right of way.
(b) Density may be increased by no more than two units per acre above the maximum amount allowable in accordance with this chapter. Such density increases may be authorized as recognition of exceptional projects by the Planning Commission for the following items:
(1) Add .75 unit per acre for sidewalk or alternate pedestrian walkway widths of five feet or greater, or sidewalks located on both sides of each street;
(2) Add .75 unit per acre for effective utilization of design techniques to add interest and variation such as:
A. Placement of all garages so that the doors do not face the street that abuts the front yard;
B. Offsetting some or all of the garages so that the front building line of the garage is behind the front building line of the dwelling portion of the unit; and
C. Emphasizing front entry features through architectural embellishment or distinctive use of materials.
(3) Retention of significant natural areas, woodlots, streams, valleys and ravines, add .25 unit per acre.
(4) Grid patterned layout based upon traditional urban planning patterns, add .25 unit per acre.
