It is intended that this zone provide areas for the development of large office and business uses.  The amenities of landscaping, high-quality design and large setbacks (at least along the boundaries) that one expects in an office/business park are also critical to the successful development of the area.  Office/business parks may also be designed with smaller lot sizes than the more campus-like development envisioned.  The requirements of this zone provide protection for uses within the zone to adjacent land uses and for adjacent, more restrictive uses.  Hotels, motels and similar uses should be located along the periphery of the zone or in such other locations that do not adversely affect the setting and quality of development for the permitted uses of this zone.
