Township of East Whiteland, PA Buffers

§ 200-59 Intent.

Buffers are intended to augment required setbacks from streets and from the perimeter of a tract where it adjoins a district boundary line by providing additional means of physical, visual, and acoustical separation between uses. Landscaped strips, screening, and shade trees required by this article are also intended to promote:

Harmony between land uses.

Reduction of glare, noise, and pollution levels.

Reduction of stormwater runoff volume.

Areas of shade that reduce temperature and energy costs during hot weather.

Natural windscreens that protect from exposure and reduce energy costs during cold weather.

Protection of environmentally sensitive areas.

Maintenance of some land on most tracts in a landscaped state to help offset the monotony of widespread pavement and buildings.

Privacy and property rights.

Attractive, shaded streets that contribute to the maintenance of an appealing community in which to live, work, and visit.

Safer means of controlling access to and from public streets.

§ 200-64 Retention of existing natural buffers.

Wherever buffers are required every effort shall be made to retain existing natural buffers, such as vegetation and topographic features. Buffers shall not include noxious weeds as defined by the Commonwealth of Pennsylvania.

§ 200-65 Landscaping of setbacks.

All required setbacks, whether or not planted with trees, shrubs, or hedges required by §§ 200-62 and/or 200-63, shall, as a minimum, consist of grass, ground cover, and/or similar vegetative material or other natural landscaping materials.

§ 200-66 Alternative buffers.

As an alternative to the potential for an excessively linear appearance brought about by strict conformance to the minimum requirements of §§ 200-62 and/or 200-63, innovative, free-form buffers that may, in some cases, not be located entirely within the minimum required setback and that may include berms, are encouraged. Such alternative buffers may be authorized; the Zoning Officer may seek the advice of technical experts in the review of the alternative plans.

§ 200-67 Maintenance required.

All buffers shall be maintained by the property owner at his expense, assuring that required trees, plantings, and vegetative materials are kept in good condition. Any such materials that die shall be replaced within six months. Alternative buffers, as defined above, may be authorized in the context of buffer maintenance.
