(a) Policies Underlying Use of Zone. The provisions of this district are provided in recognition that many industrial establishments seek to develop within unified industrial areas having all necessary services and facilities comprehensively provided in accordance with a predetermined development plan. As in the Planned Commercial Zone, provisions of this zone are formulated to encourage a high degree of coordinated development upon well landscaped premises. Particular attention is devoted to design of the periphery of the development with the objective of compatibility with surrounding land uses.
(b) Permitted Uses. Those uses included as permitted and accessory uses in the I-1 Industrial District.
(c) Arrangement of Industrial Uses. A planned industrial area shall provide for the harmony of buildings and a compact grouping in order to economize in the provision of such utility services as are required. Thoroughfares shall be kept to a minimum throughout a planned industrial area in order to reduce through traffic.
(d) Area Requirements. The minimum land area for a Planned Industrial Development shall be ten (10) acres.
(e) Structure Spacing. A minimum of fifty (50) feet shall be required between adjacent buildings.
(f) Setback and Screening. A setback of one-hundred (100) feet shall be provided along the entire perimeter of the development, except where is adjoins a Business or Industrial District in which case setback and screening requirements shall be at the discretion of the Planning Commission. Where situated adjacent to a residentially zoned area, a minimum of thirty (30) feet along the exterior property line shall be retained in natural woods, or be suitably landscaped with a dense planting of evergreens not less than four (4) feet in height at the time of planting. Such landscaping shall be fifty (50) percent or more opaque when viewed horizontally between two (2) feet and eight (8) feet above average ground level. A suitably designed fence or wall may be substituted for such screen plantings at the discretion of the Planning Commission, if in certain cases natural plantings are deemed infeasible. Screening facilities shall not obscure traffic visibility within fifty (50) feet of an intersection.
