All permitted changes of use in the LI District shall require a building permit, issued by the building department.
(1) Wherever a permitted use in the LI District is located adjacent to any other district, with the exception of a GI General Industrial District, a fully landscaped buffer 100 feet in width must be provided along the full length of the adjacency. This buffer area shall be planted and perpetually maintained with live trees and shrubs at least six feet in height and shall have such other grading and landscaping as necessary to visually and audibly screen the industrial activity from the adjacent district. The treatment of the buffer area shall, however, not appear to be unnatural or rigid, such as bunker-like straight ridges or walls, as determined by the Planning Board during its review of the site plan.
(2) All assembly, research, engineering, administration, storage and other related activities shall be conducted wholly within enclosed buildings.
(3) At no time shall any use result in or cause dissemination of dust, smoke, smog, observable gas, fumes, odors, radiation or other atmospheric pollution, objectionable noise, glare or vibrations or hazard of fire or explosion or any other physical hazard to any adjacent buildings or to any plant growth or any land adjacent to the site.
(4) The architectural treatment and general appearance of all buildings and grounds shall be in keeping with the purpose of this district and shall be of such quality of design as to be a visual asset to the area in which they are located.
