J.
The Zoning Hearing Board may impose such conditions, in addition to those required, as are necessary to assure the intent of this chapter is complied with, and which are reasonably necessary to safeguard the health, safety, morals, and general welfare of the residents of the Borough at large and the residents and owners of the property adjacent to the area in which the proposed use is to be conducted. The conditions are not limited to but may include the harmonious design of buildings, aesthetics, hours of operation, lighting, number of persons involved, noise, sanitation, safety, smoke and fume control, stormwater control, traffic control, ingress and egress provisions, open space and the minimizing of noxious, offensive or hazardous elements as well as such additional conditions to assure that the use meets the standards as set forth herein.
