Nothing herein contained shall be construed so as to limit the height of any belfry, bulkhead, chimney, church spire, clock tower, cupola, dome, silo, skylight, ventilator, water tank and other necessary mechanical appurtenances usually carried above the roof level. Such features, however, shall be erected to accomplish the purpose they are required to serve and shall not occupy in the aggregate more than 25% of the roof area of the main building.
In such cases in residential zones where the frontage on the same side of the street within 500 feet is 50% or more developed, then the required front yard for a new structure may be modified to the average for such existing development. Otherwise, the requirements of § 130-10 shall apply.
A. 
At the Planning Board's discretion, a buffer area of at least 20 feet in width constituting berms and/or screen plantings shall be provided along the boundary line between any residential district or property and commercial or industrial district or property. Such buffer area shall also be required along all boundaries between any residential district and a multiple-family district.
B. 
Buffer areas are required in addition to the yard and setback requirements of the district.
C. 
Such areas shall contain screen plantings of trees, hedges and shrubs to provide a visual and sound buffer between the different districts.
D. 
Buffers, berms and screen plantings shall be maintained by the owner of the property.
E. 
Where one property is developed along its boundary and the other is not, the provisions of the buffer area will be the responsibility of the latter property owner when the property is developed.
F. 
Fencing of approved location, height, design and material may be used for part of the required buffer area.
G. 
Where existing topography and/or landscaping provides adequate screening, the Planning Board may modify the planting and/or buffer area requirements.
H. 
Buffer areas shall not infringe on any public rights-of-way or easements.
I. 
All landscape material in a buffer area located within a sight distance triangle shall be three feet or less in height or have a clearance of at least eight feet beneath the branch or projection on corners and intersections.
