<br />1156.05 DESIGN PRINCIPLES.
<br />The following Design Principles provide certain guidelines and requirements,
<br />as noted, in the design preparation of a Preliminary PD Plan.
<br />(a) Building and Site Design
<br />(1) Wherever feasible, buildings shall be designed to provide massing
<br />configurations with a variety of different wall planes. Plain, monolithic
<br />structures with long walls and roof plane surfaces are discouraged.
<br />(2) Building facades should incorporate design elements such as changes in
<br />color or texture; projections, recesses, and reveals; arcades or pergolas providing
<br />pedestrian interest; or equivalent elements that subdivide the wall into human
<br />scale proportions. Blank facades are highly discouraged, especially on walls
<br />facing streets or pedestrian ways.
<br />(3) Commercial Building facades shall have highly visible customer
<br />enhances that feature canopies, overhangs, arcades, distinctive roof forms,
<br />arches, display windows, or landscaped features. Primary entrances should face
<br />streets on which they are located.
<br />(4) Buildings shall have well defined rooflines with attention to
<br />architectural detail. Consideration should be given to the prevailing pattern of
<br />roofs in the area surrounding and within the PD.
<br />(5) Sloping roofs, where used, shall have one (1) or more of the following
<br />architectural features: gables, hips, horizontal or vertical breaks, or other similar
<br />techniques that are to be integrated into the building architecture.
<br />(b) Building Materials. Building materials shall be limited to brick, masonry,
<br />stucco, wood, fiber, cement siding, wood shingle, wood siding, cultured stone,
<br />or other similar materials. Prohibited materials include aluminum or vinyl
<br />siding, dryvit -type products on the lowest eight (8) feet of any structure, split
<br />faced block, and other similar materials.
<br />(c) Vehicular Circulation and Access.
<br />(1) Circulation systems shall be designed to efficiently facilitate traffic
<br />flow, yet designed to discourage speeds and volumes that impede pedestrian
<br />activity and safety.
<br />(2) Street designs are encouraged to incorporate traffic calming devices and
<br />techniques.
<br />(3) Common or shared access points are encouraged.
<br />(4) To the maxhnum extent feasible, common or shared service and
<br />delivery access shall be provided between adjacent parcels or buildings, and
<br />provided to the rear of buildings.
<br />(5) Safe and adequate site distances shall be provided at all intersections.
