The proposed development must have adequate exterior lighting to provide for its safe use during periods of darkness when the site is utilized.
 

1. Lighting may be used which serves security, safety and operational needs but which does not directly or indirectly produce deleterious effects on abutting properties or which would impair the vision of a vehicle operator on adjacent roadways. Lighting fixtures must be shielded or hooded so that the lighting elements are not exposed to normal view by motorists, pedestrians, or from adjacent dwellings and so that they do not unnecessarily light the night sky. Direct or indirect illumination must not exceed 0.5 footcandles at the lot line or upon abutting residential properties.

2. All exterior lighting, except security lighting, must be turned off between 11 P.M. and 6 A.M. unless located on the site of a commercial or industrial use which is open for business during that period with Planning Board approval.

3. Wiring to light poles and standards must be underground.

B. Buffering of Adjacent Uses
 

The development must provide for the buffering of adjacent uses where there is a transition from one type of use to another use and for screening of mechanical equipment and service and storage areas.
 

1. Buffering must be designed to provide a year-round visual screen in order to minimize adverse impacts. It may consist of fencing, evergreens, berms,  rocks, boulders, mounds, or a combination thereof.

2. A development must provide sufficient buffering when topographical or other barriers do not provide reasonable screening and where there is a need to:

a. Shield neighboring properties from any adverse external effects of the development, or 
b. Shield the development from the negative impacts of adjacent uses.

3. The width of the buffer may vary depending on the treatment of the area. Within densely built-up areas, a buffer with dense plantings, fencing, or changes in grade may be as little as five (5) feet in width. A buffer with moderate levels of planting should be ten (10) feet to fifteen (15) feet in width. In suburban and rural settings, the width of the vegetated buffer should be increased to a minimum of twenty-five (25) feet. Areas adjacent to service, loading, or storage areas should be screened by dense planting, berms, fencing, or a combination thereof with a width of a minimum of five (5) feet.
 

C. Noise
 

1. The maximum permissible sound pressure level of any continuous, regular or frequent or intermittent source of sound produced by any activity on the site shall be limited by the time period and by the abutting land use as listed below. Sound levels shall be measured at least four (4) feet above ground at the property boundary of the source.

2. Noise shall be measured by a meter set on the A-weighted response scale, fast response. The meter shall meet the American National Standards Institute (ANSI S1 4- 1961) ‘American Standards Specification for General Purpose Sound Level Meters.

3. No person shall engage in construction activities, on a site abutting any residential use between the hours of 10 p.m. and 6 a.m.

D. Storage of Materials
 

1. Exposed nonresidential storage areas, exposed machinery, and areas used for the storage or collection of discarded automobiles, auto parts, metals or other articles of salvage or refuse must have sufficient setbacks and screening (such as a stockade fence or a dense evergreen hedge) to provide a visual buffer sufficient to minimize their impact on abutting residential uses and users of public streets.

2. All dumpsters or similar large collection receptacles for trash or other wastes must be located on level surfaces which are paved or graveled. Where the dumpster or receptacle is located in a yard which abuts a residential or institutional use or a public street, it must be screened by fencing or landscaping.

3. Where a potential safety hazard to children is likely to arise, physical screening sufficient to deter small children from entering the premises must be provided and maintained in good condition.
