It is the intent and purpose of this district to provide for a well designed park-like DEVELOPMENT for the permitted and CONDITIONAL USES in this Planned Office, Research and Business Park (PORBP) District to promote and encourage high-quality employment opportunities for residents of Marshall Township and economic development for the region as a whole. Design standards and requirements for this district are intended to make it compatible with the surrounding residential areas. These USES should not generate large amounts of traffic, should comply with strict performance standards and should be substantially buffered from the adjacent areas. USES in this district should not require outside storage. These regulations have been established so as to provide a healthful operating environment and for the protection of the accepted USE from encroachment of USES adverse to their operation and at the same time to reduce to a minimum their impact on surrounding USES. This district should be restricted to large TRACTS that have close proximity to PRINCIPAL ARTERIAL STREETS, are fairly level and act as a buffer between adjacent residential areas and nearby downgrading influences such as heavily traveled highways.
