    (1)

    Open space areas are defined as areas serving any one of the following four (4) basic functions:

    d.

    Conservation. Areas with unique natural qualities or physical benefits which need protection or preservation from man-built developments.

    (2)

    All planned developments shall provide open space in the form of greenbelts and buffer zones at a ratio of two (2) percent of the gross land area.

    (3)

    Open space shall be provided within the planned development based on the following ratios:

    a.

    1.

    One (1) story and two hundred thousand (200,000) square feet or greater ..... 30%

    2.

    One (1) story and less than two hundred thousand (200,000) square feet ..... 25%

    (4)

    Open space in the form of greenbelts or buffers provided within the legal description portion of the proposed phase or project may be included to meet the minimum open space criteria. Excess open space committed in prior phases adjacent to a proposed development phase may be considered to meet up to seventy-five (75) percent of the open space criteria.

    a.

    All retention ponds, fenced or nonfenced, which are meant to fulfill a portion of the open space requirements shall be designed as a project landscaping amenity. As such, they shall have curvilinear water edges which incorporate substantial curve off-sets along the water perimeter. Furthermore, all ponds shall incorporate a continuous row of drought-tolerant shrubs and understory trees along their top edge. Understory trees shall be planted at a rate of one (1) per twenty-five (25) feet of perimeter edge. Clustering of understory trees is acceptable.

    1.
