The common open space required by Section 1284.04(a)(3) shall be reserved in perpetuity for such use. Open space shall be designed and appropriate instruments shall be created according to the criteria established below.
(a) Open space shall be available and accessible to all residents of the single family cluster development, and shall be designed primarily for their use. Common open space shall be exclusive of all streets, non-recreational buildings and individually-owned land. Each dwelling unit within the single family cluster development should be designed to abut common open space areas.
(b) In order to insure that all portions of the open space network are useful for that purpose, no portion of the common open space shall have a dimension of less than fifty feet, subject to modification by the Planning Commission for smaller sections which are particularly well-designed and meet the objectives of this Chapter 1284.
(c) Common open space areas may be improved with appropriate recreation facilities and structures, such as tennis courts, pools, pavilions or other recreation features.
(d) Significant natural amenities, such as outcroppings, tree stands, ponds, ravines and stream channels should be left in their natural state and considered part of the required open space, subject to these standards.
(e) Public open space and the adjacent circulation system should be designed to limit through traffic on local streets. Public open space which is to be developed as a major activity center such as a swimming pool or recreation center should be located on a thoroughfare designed to accommodate the resulting trip desires and traffic volumes.
(f) Common open space shall be designed as a network of spaces offering pedestrian access throughout the subdivision and to maximize the number of homes which are adjacent to the open space. Common open spaces shall also include street frontage, particularly in cluster areas, to relieve the streetscape and to allow views into the open areas from the street.
(g) Stormwater detention areas may receive full credit towards the open space requirement in Section 1284.04(a)(3) if they are designed and improved for an appropriate open space or recreation use (such as a lake or play-field) in addition to storm-water detention; single purpose detention basins shall be excluded from the minimum open space requirement.
