The purpose of the Light Industry (LI) District is to provide for light manufacturing, research and testing laboratories, technological industries and like businesses. These uses require utilities and good street access but are lower in intensity than heavy industrial uses. Light industry businesses provide jobs and strengthen the economic base of the Township but do not create high levels of noise, smoke, vibrations, effluent or other negative impacts as a result of their manufacturing processes. In addition, they do not generate excessive volumes of truck or other traffic. Residential uses are not permitted in this district.
