The I-L district provides land for warehouse, office, and low intensity industrial uses in areas near residential and commercial zones. It is intended for industrial uses which involve the lowest level of noise, vibration, air pollution, radiation, glare, or fire and explosive hazards. This district is not intended to be retail customer-oriented, and retailing shall be permitted as an accessory use only or as specifically allowed. Because of the locational character and proximity of the I-L district to residential lands, restrictive performance standards shall be imposed to limit the physical effects of industrial activities to levels as per the performance standards set forth in Article V.
