(A) Open space.
(1) No PD District shall be approved, unless the design provides for the prescribed percentage of permanent landscaped or natural open space. Open space may be designated through the use of common area or other legal mechanisms such as conservation easements to the satisfaction of the Plan Commission and Common Council.
(2) The minimum required permanent open space shall be as follows:
(a) Fifty percent when the original zoning district was PR;
(b) Thirty-five percent when the original zoning district was AG or IA;
(c) Twenty-five percent when the original zoning district was R1, R2 or R3;
(d) Twenty percent when the original zoning district was UR, M1, M2, MP, UV, IS, NC, LC, GC, OC, CB, HC, EP, IC, I1 or I2; and
(e) Forty percent when the original zoning district was HI.
(B) Mixed-uses. In the case of a mixed-uses development, single-family areas shall generally have 25% permanent open space and non-single-family areas shall generally have 20% permanent open space. The distribution of permanent open space shall strive to preserve existing natural features (e.g., woodlots and wetlands).
(C) Development in stages. If the planned development is to be constructed in phases, permanent open space shall be provided for each phase of the development.
