[Ord. 95-4-18-2, 4/18/1995, § 10-1]
1.
No changes shall be made to the contour of the land and no grading,
excavating, removal or destruction of the topsoil, trees or other
vegetative cover of the land shall be commenced, until such time as
a plan for minimizing erosion and sedimentation has been processed,
and reviewed by the Planning Commission, the Bucks County Conservation
District and the Board of Supervisors.
2.
Approval of the Board of Supervisors of all preliminary or final
plans of subdivision and land development does not relieve the developer
of his obligation to execute the erosion and sediment control measures
as contained in this chapter.
3.
Final approval of plans and specifications by the Bucks County Conservation
District for the control of erosion and sedimentation shall be concurrent
with the approval of the plans of subdivision or land development
and become a part thereof. Final plans for minimizing erosion and
sedimentation as approved shall be incorporated in the agreement and
financial security requirements as required by the Township.
[Amended by Ord. 2011-02, 5/3/2011]
4.
At the time a building permit is applied for, a review shall be conducted
by the Township Engineer to insure conformance with the plan as approved.
During construction, further consultative technical assistance will
be furnished, if necessary, by the Bucks County Conservation District.
During the development phase, the Township Engineer shall inspect
the development site and enforce compliance with the approved erosion
and sediment control plans.
[Ord. 95-4-18-2, 4/18/1995, § 9-37; as amended by Ord. 00-7-18-2, 7/18/2000, § XLIII, XLIV
& XLV]
1.
Measures used to control erosion and reduce sedimentation shall,
as a minimum, meet the standards and specifications of the Bucks County
Conservation District. In cases where the Bucks County Conservation
District does not have standards and specifications for erosion and
sedimentation control, other known and commonly accepted standards
and specifications may be used as approved by the Township Engineer.
2.
The following measures to minimize erosion and sedimentation shall
be included where applicable in the control plan:
A.
Stripping of vegetation, regrading or other development shall be
done in a way that will minimize erosion.
B.
Development plans shall preserve salient natural features, keep cut
and fill operations to a minimum and ensure conformity with topography
so as to create the least erosion potential and adequately control
the volume and velocity of surface water runoff.
C.
Whenever feasible, natural vegetation shall be retained, protected
and supplemented. The maximum bare earthen area (without vegetative
cover) shall not exceed five acres or 20% of the total area of the
site at any one time (whichever is greater).
D.
Maximum time of exposure for bare areas shall be 72 hours before
stabilization measures must be implemented, or as otherwise required
by the Bucks County Conservation District, whichever is less. Stabilization
measures, including seeding/mulching, hydroseeding/mulching, installation
of revegetative netting, placement of sod, and/or any other method
of stabilization authorized by the Bucks County Conservation District
shall be immediately implemented. Revegetative netting and/or staked
sod must be utilized to stabilize slopes exceeding 8% on land that
has been disturbed.
[Amended by Ord. 2011-02, 5/3/2011]
E.
Stormwater management facilities intended to be utilized as sedimentation
control structures during earth disturbance activities shall be constructed
and stabilized in accordance with requirements of Bucks County Conservation
District and the approved plan, prior to initiating additional site
disturbance within the tributary area of the stormwater management
facilities.
[Amended by Ord. 2011-02, 5/3/2011]
F.
Temporary vegetation and/or mulching shall be used to protect exposed
critical areas during development.
G.
The permanent (final) vegetation and mechanical erosion control and
drainage shall be installed as soon as practical in the development.
H.
Provisions shall be made to accommodate effectively the increased
runoff caused by changed soil and surface conditions during and after
development within the site, where necessary, the rate of surface
water runoff will be mechanically retarded.
I.
Sediment in the runoff water shall be trapped until the disturbed
area is stabilized by the use of debris basins, or similar sediment
basins, silt traps or similar measures.
J.
Sedimentation basins must use best available technology to prevent
TSS (total suspended solids-clay fines) levels from exceeding 80 mg/1.
Best available technology includes fabric baffle systems, Faircloth
skimmers, and turbidity traps.
K.
During
grading operations, necessary measures for dust control must be exercised.
[Amended by Ord. 2011-02, 5/3/2011]
L.
Tire
cleaning areas shall be provided at each point of access to the development
site, and at each driveway access on individual lots within the development,
to minimize the potential for mud and debris from being tracked onto
the cartway of existing public roadways and the paved cartway of the
internal roadway network.
[Amended by Ord. 2011-02, 5/3/2011]

1.
Whenever sedimentation is caused by stripping of vegetation, regrading
or other development, it shall be the responsibility of the person,
corporation or other entity causing such sedimentation to remove it
from all affected surfaces, drainage systems and watercourses on-
and off-site, and to repair any damage at his expense as quickly as
possible.
2.
Maintenance of all drainage facilities and all watercourses, both
existing and proposed, within any proposed subdivision or land development
shall be the responsibility of the developer until such time as one
of the following is accomplished:
A.
An easement for these facilities is offered for dedication by the
developer and is accepted by the Township, it shall then be responsibility
of the Township.
B.
If an easement acceptable to the Township is established, the maintenance
shall then be the responsibility of the individual lot owners over
whose property the easement passes. For land developments, the maintenance
shall be the responsibility of the owner.
C.
A homeowners' association or other approved legal entity, approved
by the Township, assumes the responsibility for the maintenance of
the development, including the maintenance of the watercourses and/or
drainage facilities.
3.
It is the responsibility of any person, corporation, or other entity
doing any work on or across a stream, watercourse, or swale or upon
the floodplain or right-of-way during the period of the work, to return
it to its original or equal condition after such activity is completed.
4.
No person, corporation, or other such entity shall block, impede
the flow of, alter, construct any structure or deposit any material
or thing or perform any work which will affect normal or flood flow
in any communal stream or watercourse without having obtained prior
approval from the Township and/or Department of Environmental Protection,
whichever is applicable.
5.
Each person, corporation or other entity which makes any surface
changes shall be required to:
A.
Collect on-site surface runoff and control it to a point of discharge
into the natural watercourse of the drainage area.
B.
Control existing off-site runoff through his development by designing
it to adequately control all upstream runoff.
C.
Provide and install at his expense, in accordance with Township requirements,
all drainage and erosion control improvements (temporary and permanent)
as required by the approved erosion and sediment control plan.
