The uses permitted under this section are subject to the following provisions:
A. All operations are conducted and all materials used in such operations or held in storage are contained within enclosed buildings or enclosed by a solid wall, fence or planting of such nature and height as to conceal such operation or materials from view from any public way or area or neighboring premises.
B. Waste materials produced by such operations are either disposed of, stored in buildings or enclosed as specified in Subsection
A above.
C. Dust, smoke, fumes, gas, glare, noxious odors, noise and vibrations are limited so as not to be injurious to the public health or to the use of neighboring property as provided by the laws of the commonwealth.
D. No more than 80% of the lot is covered by "improvements," meaning buildings, parking areas, driveways and access roads, and outside storage and assembly areas.
E. Buildings housing manufacturing operations shall be set back at least 50 feet from any street and side lot line and at least 40 feet from any rear lot line. The setback areas shall be left in a natural, unimpaired state or landscaped.
F. Structures greater than three floors or 40 feet in height shall maintain a setback of at least 200 feet from the nearest street or from any General or Residential Districts.
G. Adequate provision is made for the off-street accommodation of all vehicles, including those of employers, employees, customers and visitors.
H. Illumination of buildings, yards and signs shall not constitute a hazard to auto drivers and the light sources of such illumination shall be shielded from adjacent residential districts and streets. Flashing, moving or intermittent illumination shall not be permitted.
