The Light Industrial District is designed primarily to provide for modern, low impact research and industrial establishments with a view to encouraging attractive, low lot coverage development in areas which are particularly well suited for such uses, in concert with the Pennsbury Township Comprehensive Plan of 2006, as amended. In promoting the general purposes of this chapter, the intent of the LI District is to encourage only those types of industrial uses which would not constitute a hazard or a nuisance to the population of the adjacent areas. Use of toxic materials, such as those used in metal plating, is strictly prohibited.
