[Ord. 1-1975, 2/24/1975, § 600]
1.
Notwithstanding any provision of this chapter or any condition of
the grading permit, the permittee is responsible for the prevention
of damage to other property, or personal injury, which may be effected
by the activity requiring a grading permit.
2.
No person, firm or corporation shall modify, fill, excavate, pave,
grade, or regrade land in any manner so close to a property line as
to endanger or damage any adjoining street, alley, or any other public
or private property without supporting and protecting such property
from settling, cracking, erosion, sediment, flooding, or any other
physical damage or personal injury which might result.
3.
No person, firm or corporation shall deposit or place any debris
or any other material whatsoever, or cause such to be thrown or placed,
in any drainage ditch or drainage structure in such a manner as to
obstruct free flow.
4.
No person, firm, or corporation shall fail to adequately maintain
in good operating order, any drainage facility on his premises. All
drainage ditches, culverts, drain pipes, and drainage structures shall
be kept open and free flowing at all times.
5.
The owner of any property on which any work has been done pursuant
to a grading permit granted under this chapter shall continuously
maintain and repair all graded surfaces and anti-erosion devices,
retaining walls, drainage structures or means and other protective
devices, plantings and ground cover, installed or completed. The Township
is responsible for maintenance and repair within the right-of-way
of Township roads.
6.
All graded surfaces shall be permanently seeded, sodded and/or planted,
or otherwise protected from erosion within 30 days, weather permitting,
and shall be tended and/or maintained until growth, or in the case
of vegetation, is well established. The disturbed area and duration
of exposure shall be kept to a minimum using temporary erosion and
sediment control measures immediately, as outlined in the "Erosion
and Sediment Control Handbook, Delaware County, Pennsylvania 1973,"
as amended.
7.
All trees in area of extreme grade change shall be protected with
suitable tree wells, unless the necessity for removal is established.
Precautions shall be taken to prevent the unnecessary removal of trees.
8.
When required, adequate provisions shall be made for dust control
measures as are deemed acceptable by the Township Engineer.
9.
All plans and specifications submitted for a grading permit shall
include provisions for both interim (temporary) and ultimate (permanent)
erosion and sediment control.
A.
The design, installation and maintenance of erosion and sediment
control measures shall be accomplished in accordance with standards
and specifications established by the Delaware County Soil Conservation
District as adopted from standards and specifications of the United
States Soil Conservation Service, and as outlined in the "Erosion
and Sediment Control Handbook, Delaware County, Pennsylvania 1973,"
as amended.
(1)
Technical standards for the design and installation of erosion
and sediment control measures are on file with the Township Secretary,
the Office of the County Conservation District and other governmental
agency offices.

ordinance and by the County Conservation District include, but are
not limited to the following basic conservation measures:

A quality control program is critical for fills; therefore, wherever
fill material is to be used, the person, firm, or corporation shall
be responsible for testing to determine its dry density as per ASTM
D 1556. The density of each layer shall be not less than 95% of maximum
dry density as determined by ASTM D 1557.
