The Limited Industrial District (LI) is intended to establish strict performance standards to control potentially adverse environmental effects resulting from development of permitted uses and establish operational, dimensional and landscaping standards minimizing adverse impacts on surrounding uses and districts, while also preserving the opportunity for an industrial land use within a confined portion of the Borough.
A building may be erected, altered or used, and a lot may be occupied or used, in whole or in part, for any of the uses indicated in the Appendix A, Permitted Use Matrix,[1] and no other, provided that such uses shall comply with the district regulations established in this article, Article IV, Use Regulations (in the event of a conflict between district and use regulations, the more stringent regulation shall be applicable), and all other applicable sections of this chapter.
