A.
Maximum slope steepness of a cut shall be two horizontal to one vertical
for minimizing erosion and landslide hazards.
B.
The top or bottom edge of final slopes shall be set back five feet
from adjacent property lines or road right-of-way lines in order to
permit the normal rounding of the edge without encroaching on the
abutting property or road and to allow for location of proper drainage
facilities and protective devices.
C.
Before commencing any excavation which will in any way affect an
adjoining property or structures thereon, the applicant shall be required
by the Borough to notify in writing by certified mail, return receipt
requested, the owners of the adjacent property or structures at least
30 days prior to the commencement of excavation operations. Copies
of all such notices shall be supplied to the Zoning Officer.
D.
If advised by the Borough Engineer or Consulting Engineer, the Zoning
Officer may require an excavation to be made with a cut slope flatter
than those specified in this chapter if the material in which the
excavation is to be made is subject to excessive erosion or landslides.
E.
Excavations adjacent to any footing, foundation or structure shall
not extend below the minimum angle of repose or natural slope of the
soil under the nearest point of same unless such footing, foundation
or structure is first properly underpinned or otherwise protected
against settlement.
A.
No fill shall be made in the Borough which creates a slope steeper than two horizontal to one vertical, except as provided for under § 79-9C of this chapter.
B.
The top or bottom edge of final slopes shall be set back five feet
from adjacent property lines or road right-of-way lines in order to
permit the normal rounding of the edge without encroaching on the
abutting property or road and to allow for location of proper drainage
facilities and protective devices.
C.
Whenever a fill is to be made of materials other than clean soil
or earth, the grading permit shall be subject to the following additional
limitations and requirements:
(1)
The fill shall be completed within a reasonable length of time as
determined by the soils engineer and specified on the grading permit.
(2)
Clean soil or earth shall be placed over the top and exposed surfaces
of the fill to a depth sufficient to effectively conceal all materials
used in the fill other than clean soil or earth. If the filling operation
is intermittent, the Consulting or Borough Engineer may require that
the top and exposed surfaces of the fill be so covered at the completion
of each lift.
(3)
No fill of any kind shall be placed over topsoil, trees, stumps or
other material which would create a nuisance, potential fire hazard
or sanitary problem such as decomposition which would attract rodents,
termites or other pests.
D.
Where fills are located so that earth movement may result in personal
injury or damage to adjacent property, roads or structures, the bearing
value and stability of the material under proposed fills and embankments
shall be determined by subsurface investigation performed by the applicant's
professional engineer and approved by the Borough's Engineer
or Consulting Engineer.
E.
Rock may be incorporated in fills and embankments but only in layers
24 inches thick, maximum, as per the current edition of the Pennsylvania
Department of Transportation's Publication 408, with voids filled
and a blanket of compacted fill separating one layer of rock from
the next. Rock fill shall not be placed near the bottom of foundations,
building caissons and subsurface utility installations. Suitable earth
shall be reserved or provided to cover rock fill under proposed seeded
or planted areas.
F.
No unsuitable material, including but not limited to coal, boney,
reddog, expansive shale, cinders, wood, or solid waste decomposable
material, shall be placed in fill areas.
G.
On any fills or embankments, a toe bench shall be constructed below
mantle under the toe of fill.
H.
Where fills are placed on existing slopes of 5% or more, benching
of the existing surface shall be required and indicated on the cross
sections.
I.
A porous drain shall be installed on the bottom and back wall of
the toe bench, together with a pipe and suitable discharge pipe to
the existing nonerosive surface beyond and below the toe of the proposed
fill.
J.
Overfilling of slopes is desirable to permit final shaping of surface
to proposed grade without the addition of loose fill over the surface
of the slope, provided that no fill shall be higher than 10 feet vertically
before the slope is shaped to proper grade.
K.
At the end of each workday, the horizontal surface of the fill area
shall be shaped, compacted and rolled to the outside edge to provide
for drainage.
L.
All fills shall be compacted to provide stability of materials and
to prevent undesirable settlement. The fill (except rock fill) shall
be spread in layers, not exceeding 12 inches in thickness, as per
the current edition of the Pennsylvania Department of Transportation's
Publication 408. The Borough may require tests or other information
if, in its opinion, the conditions or materials are such that additional
information is needed. Wherever fills are to have roads, structures,
or utilities placed in or on them, a modified proctor density of 95%
shall be achieved (ASTM Test Designation D 1557-78).
The standards and requirements for minimizing soil erosion and
sedimentation are found in the Erosion and Sedimentation Pollution
Control Ordinance, as amended from time to time.
B.
Retaining walls must be designed and constructed in accordance with
sound engineering practice. The plans submitted for approval shall
bear the signature and the seal of a professional engineer or architect
who designed them.
C.
Repairs to and replacements of an existing retaining wall may be
made upon written approval of the Borough Engineer, consistent with
sound engineering practices and the applicable provisions of this
chapter.
The standards and requirements for stormwater drainage controls
are found in any stormwater management ordinance, as amended from
time to time.
A.
The property owner on which a grading, excavation and/or fill operation
has taken place shall maintain in good condition and repair any permitted
grading, excavation and/or fill and any protective devices which may
be a part of the grading, excavation, and/or fill operation.
B.
If at any time subsequent to the completion of the grading work,
the cut face or fill slope shows evident signs of deterioration, erosion
or other evidence which might be detrimental to the properties above
or below the development site, the Borough, upon the recommendation
of the Borough Engineer or Consulting Engineer, may direct the property
owner to take whatever necessary remedial steps are deemed necessary
to restore the development site to a safe condition and to do so in
a reasonable period of time.
C.
If after such notification the property owner has not made the necessary
repairs within the allotted time, Borough Council may direct Borough
agents or employees to make the required repairs and the cost shall
be borne by the property owner by a lien filed as provided by law.
The following general working conditions shall apply to all
development sites:
A.
Dust control. During grading, excavation, and/or fill operations
necessary measures for dust control, including without limitation
water spray, shall be utilized.
B.
Cleanup. All soil washed or carried onto any public or private roads
during grading operations shall be cleaned up each day. Temporary
driveway or road surfaces shall be provided as soon as possible. The
owner of the property being graded, excavated, and/or filled shall
be responsible to protect and clean up lower properties of silt and
debris which have washed down onto the lower properties as a result
of the grading, excavation, and/or fill in a reasonable period of
time.
