Guidelines for the provision of neighborhood open space. The purpose of this subsection is to provide and emphasize safe and inviting traditional neighborhood urban open spaces such as squares, parks, and greenways, and to integrate them into the neighborhood pattern for the active and passive enjoyment of neighborhood residents and their guests. Urban neighborhood open space should be planned and improved to be accessible and usable by persons living or working nearby. Urban characteristics are structured, formal and dense. Whereas, rural characteristics are more informal, complement natural features and have low density. Rural open space development should preserve wood lots, open fields, wetlands and other natural features. Except for areas designated as preserves, it should be cleared of underbrush and debris and may contain one or more of the following or similar improvements: landscaping, walks, benches, seating areas, fountains, ponds, ball fields, trails and playground equipment. In all cases stands of trees, streamside areas and other valuable topographic features should be preserved within the open space areas.
