Buffer Yards. A landscaped buffer yard shall be provided and maintained between any nonresidential use which borders a residential use or district (R-1, R-1A, R-2 and R-3) and between any industrial use which borders a street, a nonindustrial use, or a nonindustrial district (R-1, R-1A, R-2, R-3, TC, NC, HC-1, HC-2, GC, MX, C, and H). The Borough Council may modify buffer requirements between nonresidential uses and residential uses where appropriate to accommodate intended mixed use areas. The required buffer yards shall comply with the following standards:
A.
Size, Location.
(1)
A twenty-foot wide buffer yard shall be required unless otherwise indicated in this chapter. Where an industrial use borders a street, a non-industrial use or a non-industrial district, the buffer yard shall be 30 feet in width. However, along the boundaries of any Heavy Industrial District (HI) or Intermediate Industrial District (II), the buffer yard shall be 50 feet in width.
(2)
The buffer yard shall be measured from the district boundary line or from the street right-of-way line (where a street serves as the district boundary line). Buffer yards shall not be within an existing or future street right-of-way and shall be in addition to that right-of-way.
(3)
The buffer yard may be coterminous with a required front, side, or rear yard, provided the larger yard requirement shall apply in case of conflict.
B.
Characteristics.
(1)
The buffer yard shall be a landscaped area free of any principal or accessory building or structures, manufacturing or processing activity, outdoor storage, or vehicular parking. No driveways or streets shall be permitted in the buffer yards except at points of ingress or egress provided it crosses the buffer with the minimum possible displacement of buffer plantings.
(2)
All buffer yards shall contain a planting screen in accordance with the requirements in Subsections 4C and E below. All areas not within the planting screen shall be planted with grass seed, sod or ground cover, and shall be maintained and kept clean of all debris, rubbish, grass more than 12 inches in height, or weeds.
C.
Planting Screen.
(1)
Each buffer yard shall include a planting screen of trees, shrubs, and/or other plant materials extending the full length of the lot line to serve as a barrier to visibility, airborne particles, glare and noise.
(2)
Each planting screen shall be in accordance with the following requirements:
(a)
Plant materials used in the planting screen shall be of such species and size as will produce, within two years, a complete year-round visual screen of at least eight feet in height.
(b)
The planting screen shall be permanently maintained by the landowner and any plant material which does not live shall be replaced within 18 months.
(c)
The planting screen shall be so placed that at maturity it will be at least three feet from any street or property line.
(d)
The planting screen shall be broken only at points of vehicular or pedestrian access.
(e)
A clear sight triangle shall be maintained at all street intersections and at all points where private accessways intersect public streets in accordance with § 27-401, Subsection 3, of this chapter.
(3)
In circumstances where it is impractical for a planting screen to meet all the requirements of this section or would create an undue hardship, the Zoning Hearing Board may modify the requirements or approve acceptable alternatives which shall satisfy the spirit, objectives and intent of the screen requirements.
D.
Equipment Screening. All mechanical and electrical equipment not enclosed in a building shall be fully screened from view from any point from a public street or an adjacent residential use in a manner compatible with the architectural and landscaping style of the lot so that it blends with the landscape.
E.
Planting Requirements. The standards below indicate the amount of plant material that is required per linear foot of property line. Plantings shall be placed within the minimum width of the buffer area. The Planning Commission may permit staggering or grouping of plant materials provided a satisfactory buffer is achieved.
