A. 
Landscaping.
(1) 
Before commencing any use of such building or enlargement, landscape planting, including trees, shrubs, and grass or ground cover, shall be provided and permanently maintained by the owner in the area required for setback from property and street lines and specifically:
(a) 
All lots used in an industrial district shall provide a strip of land not less than six feet wide, adjacent to and extending for the length of the street line, which strip shall be put in lawn or otherwise suitably landscaped and planted. Such strip may be transversed by not more than two driveways, and one additional driveway for each 200 feet of frontage of the lot in excess of 300 feet. Not more than 60% of the area of the required setback from the street shall be used for driveways or for parking, and the balance shall be put in lawn or suitably landscaped and planted and shall at all times during use of such building or enlargement be maintained in good appearance. Parking in the required setback from the street shall be for passenger vehicles only, and no portion of the required setback shall be used for storage or for any purpose except as herein provided.
(b) 
Any tree of more than 10 inches in caliper (diameter) measured a yard above the ground shall be shown on plot plans and shall be maintained unless it hampers utilities, structures or reasonable working room during construction.
(c) 
All other existing natural growth shall be preserved and maintained where practicable.
(d) 
Where a property adjoins a residence district on the side or rear, a greenbelt shall be planted and maintained at 30 feet in depth, including conifers planted in no fewer than two rows no further than 7.5 feet apart with trees planted no fewer than 15 feet apart along each row, staggered to provide maximum screening, and using trees not less than two inches in caliper at time of planting.
[Amended 5-18-2004]
(2) 
The Commission may require more extensive plantings, or more mature plantings, if unusual conditions demand more extensive screening and noise abatement.

(3) 
Whenever the owner or occupant desires to commence the permitted use of such building or enlargement before providing the landscape planting prescribed hereunder, the Commission may extend the time to a date certain following commencement of such use, but not exceeding six months, upon application by such owner or occupant, if in the opinion of the Commission provision of such landscape planting cannot be made before commencing such use solely because normal seasonal or abnormal unseasonable weather and soil conditions present an unreasonable risk of planting failure.
B. 
Storage areas. Storage areas for materials, supplies and products shall not be located in the front of the building, and, before commencing any such use of such building or enlargement, all such areas shall be screened by planting, landscaping or fencing.
C.
