C. 
Action by the Planning Commission. Upon the filing of an application for a conditional use, the Borough Council shall submit each such conditional use application to the Planning Commission at least 30 days prior to the hearing on such conditional use to provide the Planning Commission an opportunity to submit recommendations.

A buffer zone shall be required in this district in order to minimize the effects of glare from headlights of vehicles, lights from structures, noise and to shield activities from adjacent residential and commercial properties. A buffer zone shall comply with the following requirements:
A. 
A buffer area shall provide a year-round visual screen and be at least 10 feet in depth where any property in the Manufacturing and Industrial District is adjacent to a property in the Commercial District, and shall be at least 15 feet in depth where any property in the Manufacturing and Industrial District is adjacent to property in the Residential or Historic District. The buffer area may consist of one or a combination of the following:
(1) 
Evergreen and deciduous plant material of varying species.
(2) 
An existing natural land form or wooded area.
(3) 
A fence between five feet and eight feet in height with at least 60% of the surface being opaque.
B. 
When a planted buffer is utilized, it shall consist of a mix of evergreen and deciduous plant materials. At the time of planting, the evergreen material shall be sufficient to screen the property visually and shall be a minimum of five feet in height (after planting). The remainder of the plantings may be of varying lesser heights.
C. 
The property owner shall be responsible for the continuing maintenance of all buffer areas, including the replacement of any dead plant material. Buffer areas shall be kept clean of all debris, rubbish, weeds and tall grass.

E. 
The buffer area shall be continuous along property lines where they are required, except for points of vehicular or pedestrian access.
F. 
Plans for any buffer area shall be received by the Planning Commission prior to the issuance of the building permit.
