TABLE 9: Civic Space.  The intended types of civic space are diagrammed and described in this table. The diagrams are only illustrative; specific designs would be prepared in accordance to the verbal descriptions on this table.
Park: a natural preserve available for unstructured recreation. A park may be independent of surrounding building frontages. Its landscape shall consist of pedestrian walkways and trails, meadows, waterbodies, woodland and open shelters, all naturalistically disposed. Parks may be lineal, following the trajectories of natural corridors. The minimum size shall be 8 acres.
Square: an open space available for unstructured recreation and civic purposes. A square is spatially defined by building frontages. Its landscape shall consist of pedestrian walkways, lawns and trees, formally disposed. Squares shall be located at the intersection of important thoroughfares. The minimum size shall be 1/2 acre and the maximum shall be 5 acres.
Green: an open space available for unstructured recreation. A green may be spatially defined by landscaping rather than building frontages. Its landscape shall consist of lawn and trees, naturalistically disposed. The minimum size shall be 1/2 acre and the maximum shall be 8 acres.
Plaza: an open space available for civic purposes and commercial activities. A plaza shall be spatially defined by building frontages. Its landscape shall consist primarily of pavement. Trees are optional. Plazas should be located at the intersection of important streets. The minimum size shall be 1/2 acre and the maximum shall be 2 acres.
Playground: an open space designed and equipped for the recreation of children. A playground should be fenced and may include an open shelter. Playgrounds shall be interspersed within residential areas and may be placed within a block. Playgrounds may be included within parks and greens. There shall be no minimum or maximum size.

TABLE 10: Building Disposition.  This table approximates the location of the building relative to the boundaries of each individual lot. Each of these very general types is intrinsically more or less urban, depending on the extent that it completes the frontage.
Edgeyard: specific types - single family house, cottage, villa, estate house, urban villa. A building that occupies the center of its lot with setbacks on all sides. This is the least urban of types as the front yard sets it back from the frontage, while the side yards weaken the spatial definition of the public thoroughfare space. The front yard is intended to be visually continuous with the yards of adjacent buildings. The rear yard can be secured for privacy by fences and a well-placed backbuilding and/ or outbuilding.
Sideyard: specific types - Charleston single house, double house, zero-lot-line house, and twin. A building hat occupies one side of the lot with the setback to the other side. A shallow frontage setback defines a more urban condition. If the adjacent building is similar with a blank side wall, the yard can be quite private. This type permits systematic climatic orientation in response to the sun or the breeze. If a sideyard house abuts a neighboring sideyard house, the type is known as a twin or double house. Energy costs and sometimes noise are reduced by sharing a party wall in this disposition.
Rearyard: specific types - townhouse, rowhouse, live-work unit, loft building, apartment house, mixed use block, flex building, perimeter block. A building that ccupies the full frontage, leaving the rear of the lot as the sole yard. This is a very urban type as the continuous façade steadily defines the public thoroughfare. The rear elevations may be articulated for functional purposes. In its residential form, this type is the rowhouse. For its commercial form, the rear yard can accommodate substantial parking.
Courtyard: specific types - patio house. A building that occupies the boundaries of its lot while internally defining one or more private patios. This is the most urban of types, as it is able to shield the private realm from all sides while strongly defining the public thoroughfare. Because of its ability to accommodate incompatible activities, masking them from all sides, it is recommended for workshops, lodging and schools. The high security provided by the continuous enclosure is useful for crime-prone areas.
