The district also allows such commercial uses that serve primarily the industrial district. The standards in this chapter are intended to protect the light industrial area from uses which may interfere with efficient industrial operations, while at the same time protecting adjacent areas from adverse industrial impacts.; Controls to provide freedom from nuisance-creating features such as noise, dirt, odor, vibration, air and water pollution, are established together with adequate traffic circulation, open space and landscaping requirements, to establish compatibility with surrounding residential, commercial or other development and offer protection from industrial blight.
