Whenever any subdivision is proposed, any new construction or installation of a new structure under Chapter
240, Zoning, or other activity which results in application to the Cambria County Soil Conservation District and submission of a soil and erosion control plan, a copy of said plan and final approval and/or permits as may be granted shall be submitted to the township prior to any activity, construction, grading or relandscaping of the affected tract being undertaken. The township shall also be provided with a copy of said application, final approval and/or permit such as will allow full and complete review of the proposal as completed. The township shall have full and complete authority to inspect the activities undertaken at said site, including the full right of ingress and egress to the property, and shall have the authority to terminate, stop or suspend activities or conduct not in compliance with such approvals and/or permits as may be issued.
Whenever any subdivision approved under Chapter
215, Subdivision and Land Development, any new construction or installation of a new structure under Chapter
240, Zoning, or any change in use which causes the landscape to be permanently disturbed as to either contours, soil or slope characteristics, vegetation or any ground cover is to be permanently removed, except as hereinafter excluded under §§
204-7 and
204-8, and except as otherwise subject to review and approval by the Cambria County Soil Conservation District as provided under §
204-5, a plan is required showing how resulting erosion and sediment shall be controlled. This plan shall include the following:
A. The amount of site alteration proposed.
C. Erosion and sediment control practices (both temporary
and permanent) and the operation and maintenance arrangements.
Except for those situations which have been approved by issuance of a permit by the Cambria County Soil Conservation District as set forth in §
204-5 and those activities exempted by §
204-8, the following activities require a grading permit:
A. Modifying, disturbing, blocking, diverting or otherwise
adversely affecting the natural overland or subsurface flow of stormwater.
B. Construction, erection or installation of any drainage
dam, ditch, culvert, drain pipe, bridge or any other structure or obstruction
affecting the drainage of any premises.
C. Disturbing the landscape, vegetation or any ground cover by any proposal involving an area in excess of 20,000 square feet unless covered by Subsection
A or
B above.
The following activities do not require a grading permit:
A. Improvements, such as erection of retaining walls, driveway
paving or sidewalks.
B. Farming, gardening, lawn installation or lawn restoration,
but not including sod farming.
C. Work within the right-of-way of a public street or alleyway
to be offered for dedication or previously ordained by the township, county
or commonwealth, or any park, playground, recreation area or open space dedicated
to and accepted by the township, county or commonwealth.
In addition to the requirements of §
204-10, and where deemed necessary by the Planning Commission and the Board of Supervisors, the applicant shall submit with the plan a detailed drainage study prepared by a registered professional engineer or surveyor licensed in the commonwealth. This study shall include:
A. A plan of the property showing the location of all present
and proposed ditches, streams, pipes and other drainage structures and proposed
cuts and/or fills. In addition to showing present elevations and dimensions
and location and extent of all proposed grading and/or drainage, the plan
shall clearly indicate all woodlands, buildings, parking areas and driveways.
Further, the plan shall indicate the present and proposed sources, storage
and disposition of water being channeled through or across the premises, together
with elevations, gradients and maximum flow rates. The plan shall describe
the work to be performed and disposition of cut and/or fill, the materials
to be used and the manner or method of performance, including provisions for
protecting and maintaining existing drainage facilities whether on public
or private property. The applicant shall also supply the supporting data for
the plan as developed by the engineer or surveyor.
B. A soils investigation report, when requested, when load-bearing
fill is proposed. This report shall consist of test borings, laboratory testing
and engineering analysis to correlate surface and subsurface conditions with
the proposed grading plan. The results of the investigation shall be presented
in a report by a registered professional engineer and shall include data regarding
the nature, distribution and supporting ability of existing soils and rocks
on the site, conclusions and recommendations to ensure stable soil conditions
and groundwater control, as applicable. The Township of Richland may require
such supplemental reports and data as is deemed necessary. Recommendations
included in such reports and approved by the township shall be incorporated
in the plan or specifications. In addition:
(1) Fills toeing out on natural slopes steeper than two horizontal
to one vertical shall not be made unless a report is received which is deemed
acceptable by the township and approved by the Board of Supervisors. The report
shall be made by a registered professional engineer certifying that he has
investigated the property, made soils tests and that, in his opinion, such
steeper slopes will safely support the proposed fill.
Upon the approval of the plan by the Planning Commission, the township
shall issue the necessary grading plan approval.
Except for those activities exempted by §
204-8, the following standards shall apply to all activities permitted or allowed under §§
204-5 and
204-7 of this chapter:
A. Notwithstanding any provisions 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 affected by the
activity requiring a grading permit.
B. No person, firm or corporation shall modify, fill, excavate,
pave, grade or regrade land in any manner so close to a property line that
would 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.
C. Notwithstanding any other term or provision of this chapter,
no person, firm or corporation shall cause or allow to be removed greater
than 50% of the existing topsoil from any site, and in no event shall the
topsoil existing on any site be reduced to less than a depth of six inches
as measured from the underlying subsoil except what may be modified by the
township by issuance of a conditional permit, which permit shall be issued
to modify the terms of this chapter only based upon sound engineering practices
and subject to appeal by any party in interest, including the applicant, the
township by and through the Planning Commission or any other interested or
affected party filing an appeal to be heard by the Township Zoning Hearing
Board. Further, it is the intention of this chapter to achieve conservation
of both topsoil and subsoil in such a manner that disturbance of the subsoil
will achieve a balance on each and every disturbed site.
D. 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.
E. 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.
F. 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 of Richland is responsible
for maintenance and repair within the right-of-way of municipal roads; however,
the property owner shall be responsible for new installation or replacement
of driveway piping.
G. 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 is well established.
The disturbed area and duration of exposure shall be kept to a minimum using
temporary erosion and sediment control measures immediately.
H. When required, adequate provisions shall be made for
dust control measures as are deemed acceptable by the Township Zoning Officer.
I. All plans and specifications submitted for a grading
permit shall include provisions for both interim (temporary) and ultimate
(permanent) erosion and sediment control.
J. The design, installation and maintenance of erosion and
sediment control measures shall be accomplished in accordance with standards
and specifications established by the County Soil Conservation District as
adopted from standards and specifications of the United States Soil Conservation
Service, and is outlined in the then-applicable and current handbook of administrative
regulations or guidelines as may be adopted and enacted by the County Soil
Conservation District.
(1) Technical standards for the design and installation of
erosion and sediment control measures are on file with the Township of Richland,
the office of the County Conservation District and other governmental agency
offices.
(2) Standards and specifications adopted for the purpose
of this chapter and by the County Conservation District include but are not
limited to the following basic conservation measures:
(a) Temporary cover on critical areas;
(b) Permanent grass and legume cover for critical areas on

204-5 and those activities exempted by §
204-8, the following standards shall apply:
A. All inspections shall be the responsibility of the township
or a qualified person acceptable to the township.
B. Inspections will be carried out on a random basis, except
as stated below. However, a set of "as-built" plans shall be on file at the
site and authenticated by a registered professional engineer. When it is deemed
acceptable to the township, a designated qualified person may authenticate
the as-built plans and will assume full responsibility for the quality of
work.
C. Any and all as-built plans shall be available on the
site at all times and be subject to inspection and inquiry.
D. Engineering check notes shall accompany all as-built
plans which involve structural or mechanical measures and shall serve as supporting
evidence that structures meet design standards and specifications specified
herein.
E. A final inspection shall be conducted by the township
to certify compliance with this chapter. Satisfactory compliance with this
chapter shall be necessary before issuance of an occupancy or use permit.
Any person who violates or permits a violation of this chapter shall,
upon being found liable therefor in a civil enforcement proceeding commenced
by the township before a District Justice, pay a fine of not more than $600,
plus all court costs, including reasonable attorney's fees, incurred by the
township in the enforcement of this chapter. No judgment shall be imposed
until the date of the determination of the violation by the District Justice.
If the defendant neither pays nor timely appeals the judgment, the township
may enforce the judgment pursuant to the applicable Rules of Civil Procedure.
Each day a violation exists shall constitute a separate offense. Further,
the appropriate officers or agents of the township are hereby authorized to
seek equitable relief, including injunction, to enforce compliance herewith.
In addition to other remedies provided by law, Richland Township may
institute any appropriate action or proceedings to prevent any violation of
this chapter or to restrain, correct or abate such violation, or to prevent
the use of any land which is being occupied in violation of this chapter.
In addition to the penalties as set forth in §
204-15, any movement of the landscape, vegetation or any ground cover performed in violation of this chapter shall be restored to its previous condition, including replacement of excavated earth, removal of illegally placed fill and restoration of grades and planting.
