The purpose of this chapter is:
A. To provide minimum standards to safeguard persons, protect property
and promote the general welfare by preventing excess erosion, hazardous
rock and soil slippage, sediment production and other soil and water
management problems by regulating and controlling the design, construction,
quality of materials, use, location, and maintenance of grading, excavations
and fills.
B. To establish performance standards which insure land use practices
respectful of the natural topography and capabilities of the land.
C. To encourage maximum retention of natural topography and vegetative
features on hillsides.
D. To prevent earthflow and rockfall landslides.
E. To prevent soil erosion and increases in stormwater runoff which
result in stream siltation, flooding, and damage to the property of
others.
F. To encourage imaginative and innovative site development to building
design that adapts to and takes advantage of the best use of the natural
terrain.
A grading permit shall not be required for any of the following:
A. An excavation which does not exceed three feet in vertical depth at its deepest point measured from the natural ground surface and cover a surface area of less than 1,000 square feet, provided that the surfaces of such excavation do not have slope at any point steeper than three horizontal to one vertical. However, this subsection shall not be deemed to nullify the application of this chapter, or any requirement for obtaining a grading permit, with respect to any fill made with material from such an excavation, unless otherwise excepted by Subsections
B and
C of this section.
B. A fill which does not exceed 10 cubic yards of material on any one
site.
C. Fill which is not intended to support structures and does not exceed
three feet in vertical depth at its deepest point measured from the
natural ground surface and does not cover an area of more than 1,000
square feet, provided that the surface of such fills do not have a
slope at any point steeper than three horizontal to one vertical and
does not obstruct a drainage course.
D. An excavation below finished grade for basements and footings of a building, swimming pool, or underground structure authorized by a building permit and an excavation of a driveway between a building site and the street. However this Subsection
D shall not be deemed to nullify the application of this chapter, or any requirement for obtaining a grading permit, with respect to any fill made with the material from such an excavation unless otherwise excused by Subsections
B and
C of this section.
E. Soil excavated under the authorization of a properly issued building
permit which is temporarily stockpiled on the same site as the excavation.
If, however, excavated material is stockpiled on a site for a period
of longer than 120 days, then a permit shall be necessary when disposing
of the fill material.
F. A building site improved under authorization of a properly issued building permit where the maximum natural gradient between property lines or the maximum excavation or fill, exclusive of the situations referred to in Subsection
D above, do not exceed the grades or quantities set forth in the following table:

I. Work performed by the Borough, or of contractors employed by the
Borough in a public street or alley, Borough park, playground or recreation
area or on other Borough property.
J. Normal agricultural operations, including but not limited to planting,
tilling, and seeding.
