The purpose and objective of the Conservation Overlay Districts is
to implement the goals, objectives and policies of the West Nantmeal
Township Comprehensive Plan and the Chester County Vision Partnership
Program which pertain to conservation management, environmental resource
protection, natural resources, historical preservation, and open space
preservation. In order to strategically implement theses goals, objectives
and policies, the following Conservation Overlay Districts are hereby
established:
[Amended at time of adoption of Code (see Ch. 1, General
Provisions, Art. I)]
The Conservation Overlay Districts incorporated under this article
include provisions to supplement and enhance the existing underlying
district regulations for certain land areas and water features. These
supplemental regulations should not replace the existing underlying
zoning district regulations. In cases where the Conservation Overlay
Districts should overlap, the more restrictive standards and specifications
shall apply.
The land and water areas encompassed by the Conservation Overlay
Districts shall be subject to the interpretation of the Zoning Officer.
Should a dispute arise concerning the interpretation of the boundaries
or limits of those land or water areas encompassed by the Conservation
Overlay Districts, the person aggrieved by the interpretation may
file an appeal with the Zoning Hearing Board. In all cases, the burden
of proof and submission of technical evidence shall be the responsibility
of the person appealing the interpretation of the Zoning Officer.
[Amended 7-10-2017 by Ord. No. 2017-4]
See now Article XIII, Floodplain Regulations, in this chapter for provisions relating to flood hazard districts.
The Wetlands and Hydric Soil Overlay District shall be a conservation
overlay to the underlying zoning districts of West Nantmeal Township.
The purpose and objective of the Wetlands and Hydric Soil Overlay
District Overlay District is outlined as follows:
To develop a protective zone to serve as a natural filter in the
removing of pollutants such as bacteria, acid and sediment from groundwater
and surface water.
To implement an effective hydrological and stormwater management
program that adequately addresses surface drainage, groundwater recharge
and soil erosion control measures.
To implement the recommendations concerning natural features, conservation
management and land use, as outlined within the West Nantmeal Township
Comprehensive Plan.
All areas delineated as wetlands and/or seasonal pools on the most
recent National Wetlands Inventory Maps as prepared by the United
States Fish and Wildlife Service.
For all subdivision or land development applications involving areas
with hydric soils and/or areas considered to be wetlands, a qualified
professional or soil scientist with experience in delineating wetlands
shall conduct a field investigation and delineate the limits of the
wetlands on the parcel of land being subdivided or developed. As part
of this requirement, a report containing the field investigation notes,
wetland data sheets, summary, conclusions and resume of the person(s)
responsible for the field investigation shall be issued to West Nantmeal
Township for review and consideration. Further, the subdivision plan
or land development plan shall contain a certification note that has
been endorsed by the qualified person(s) responsible for the field
investigation and the wetlands delineation, as accurately depicted
on the subdivision plan or land development plan.
No wetland encroachment or earth disturbance activities shall be
permitted unless the appropriate permits or approvals have been obtained
from the Pennsylvania Department of Environmental Protection and/or
the United States Army Corps of Engineers.
A fifty-foot buffer zone shall be applied to all areas that have
been delineated as wetlands, as measured from the perimeter of the
wetlands area. No encroachment or earth disturbance activities shall
be permitted within the required buffer zone.
A wetlands delineation shall be conducted for all areas in which
earth disturbance activities or improvements are proposed within the
Wetlands and Hydric Soil Overlay District.
The Steep Slope Overlay District shall be a conservation overlay
to the underlying zoning districts of West Nantmeal Township. The
purpose and objective of the Steep Slope Overlay District is outlined
as follows:
To protect certain land areas classified as "steep slopes" from inappropriate
subdivision and land development activity, which could result in accelerated
erosion, increased volume and velocity of stormwater, and degradation
of surface waters.
To permit only those uses of steep slopes which are compatible with
the conservation of the natural conditions, habitats and environment
by maintaining existing topographical conditions and minimizing earth
disturbance activities.
To implement the recommendations concerning natural features, conservation
management and land use, as outlined within the West Nantmeal Township
Comprehensive Plan.
Category 1 slopes: All land areas in which the topographical conditions
have a range of slope between 15% and 25% in slope in pre-development
conditions, as measured 100 feet in any straight-line direction.
Category 2 slopes: All land areas in which the topographical conditions
exceed a slope of 25% in pre-development conditions, as measured 100
feet in any straight-line direction.
All uses permitted within the underlying zoning districts shall be
permitted as part of the Steep Slope Overlay District, provided that
the lot or parcel intended to facilitate the proposed use and related
site improvements does not conflict with the provisions of the Steep
Slope Overlay District.
The following subdivision and land development provisions shall apply
to all lots or parcels, regardless of their size, whereas at least
10% of the lot or parcel includes Category 1 slopes:
The principal building and use may be located on Category 1 slopes,
provided that a professional engineer and architect licensed within
the Commonwealth of Pennsylvania submits plans and supporting documentation
to West Nantmeal Township as part of the land development plan and/or
building permit to demonstrate that the proposed construction methods
shall mitigate any adverse impacts associated with steep slopes, hydrology,
landscaping, erosion and stabilization.
Accessory buildings, uses and driveways may be located on or traverse
through Category 1 slopes, provided that it complies with all other
provisions specified by West Nantmeal Township.
The maximum building coverage for the proposed use, as specified
by the zoning district requirements, shall be reduced by 15%.
Example: If the maximum building coverage for a commercial lot
is 40% and the lot contains Category 1 slopes as the highest delineated
slope category, then the 15% reduction would limit the maximum building
coverage to 34% for that commercial lot.
The maximum lot coverage for the proposed use, as specified by the
zoning district requirements, shall be reduced by 15%.
Example: If the maximum lot coverage for a commercial lot is
60% and the lot contains Category 1 slopes as the highest delineated
slope category, then the 15% reduction would limit the maximum lot
coverage to 51% for that commercial lot.
The maximum disturbance area of lands that have been exclusively
identified as Category 1 slopes shall be limited to 50% of the total
area of the Category 1 slopes on the lot or property being developed.
The final grading on any lot or parcel with Category 1 slopes shall
not exceed a three-to-one side slope or horizontal-to-vertical ratio
for any area which has been disturbed as a result of the improvements.
Grades exceeding a three to one ratio may be permitted, provided the
following conditions apply: the grading and earth disturbance impacts
will be minimized; the stabilization of adjacent land areas will be
enhanced; the stormwater runoff will be sufficiently controlled; the
site improvements will be designed, constructed and installed considering
best engineering practices that are acceptable to West Nantmeal Township;
and the health, safety and general welfare of the community has been
considered.
The following subdivision and land development provisions shall apply
to all lots or parcels, regardless of their size, whereas at least
10% of the lot or parcel includes Category 2 slopes:
All accessory buildings, uses and driveways may be located on or
traverse through Category 2 slopes, provided that it complies with
all other provisions specified by West Nantmeal Township.
The maximum building coverage for the proposed use, as specified
by the zoning district requirements, shall be reduced by 20%.
Example: If the maximum building coverage for a residential
lot is 20% and the lot contains Category 2 slopes as the highest delineated
slope category, then the 20% reduction would limit the maximum building
coverage to 16% for that residential lot.
The maximum lot coverage for the proposed use, as specified by the
zoning district requirements, shall be reduced by 20%.
Example: If the maximum lot coverage for a residential lot is
30% and the lot contains Category 2 slopes as the highest delineated
slope category, then the 20% reduction would limit the maximum lot
coverage to 24% for that residential lot.
The maximum disturbance area of lands that have been exclusively
identified as Category 2 slopes shall be limited to 10% of the total
area of the Category 2 slopes on the lot or property being developed.
The final grading on any lot or parcel with Category 2 slopes shall
not exceed a three to one side slope or horizontal to vertical ratio
for any area which has been disturbed as a result of the improvements.
Grades exceeding a three to one ratio may be permitted, provided the
following conditions apply: the grading and earth disturbance impacts
will be minimized; the stabilization of adjacent land areas will be
enhanced; the stormwater runoff will be sufficiently controlled; the
site improvements will be designed, constructed and installed considering
best engineering practices that are acceptable to the West Nantmeal
Township; and the health, safety and general welfare of the community
has been considered.
All applications involving a building permit, subdivision and/or
land development plan shall include a detailed topographical analysis,
which includes a depiction of the slope categories at a scale of one
inch equaling 50 feet. The West Nantmeal Township Engineer and/or
Zoning Officer shall review the accuracy of the topographical analysis.
Where determined necessary by the West Nantmeal Township Engineer
and/or Zoning Officer, field verification should be conducted by the
applicant to verify the accuracy of the topographical analysis.
All slopes considered to be man-made slopes by the West Nantmeal
Township Engineer shall not be subject to the provisions specified
by the Steep Slope Overlay District.
The Woodland Protection and Management Overlay District shall be
a conservation overlay to the underlying zoning districts of West
Nantmeal Township. The purpose and objective of the Woodland Protection
and Management Overlay District is outlined as follows:
To acknowledge that woodlands are a vital resource and provide a
number of community benefits, including minimizing erosion on areas
of steep slopes and stream banks; improving groundwater quality and
quantity by filtering out pollution and sediment; providing wildlife
habitats for plants and animals; providing effective stormwater management
and erosion control; providing shade from direct sunlight and reducing
temperatures; stabilizing adverse climate conditions by providing
buffer and wind breaks; providing active and passive recreation opportunities;
enhancing the scenic characteristics; and reducing air pollution by
absorbing airborne pollutants.
To establish forestry and timber regulations that will effectively
promote good forest stewardship, protect the rights of adjoining property
owners, and minimize the potential of adverse environmental impacts
created by inappropriate timber harvesting.
To permit the sale of forestry products as an economic value and
to appreciate that forestry is a leading industry within the Commonwealth
of Pennsylvania.
To implement the recommendations concerning natural features, conservation
management and land use, as outlined within the West Nantmeal Township
Comprehensive Plan.

A property owner shall be permitted to clear trees on his or her
property without obtaining a permit from the Township, provided that
the area cleared covers no more than 10% of the gross lot area. If
the property owner or successors and assigns in title to the property
opt to perform tree clearing over time in various stages or intervals,
no permit shall be required until the total area cleared from all
stages of tree clearing by all owners of the property exceeds 10%
of the gross lot area of the lot or lots to be cleared.
Timber harvesting or logging operation on a property with 10 or more
contiguous acres where 20 or more trees with a minimum caliper of
12 inches are harvested or logged.
A landowner who is required to obtain a permit for the activities set forth in § 215-22D shall submit a permit application and pay the applicable filing fee as established by the Board of Supervisors by resolution. The application shall contain a timber harvesting plan which is prepared in accordance with the guidelines established by the Pennsylvania Department of Conservation and Natural Resources, Bureau of Forestry and/or the Penn State Cooperative Extension. The timber harvesting plan shall contain the following information:

is prohibited without the express written consent of West Nantmeal
Township or the Pennsylvania Department of Transportation, whichever
is responsible for maintenance of such public road or right-of-way.
During the periods of abnormal forest fire danger, as determined
by the fire company that serves the site of the timber harvest, West
Nantmeal Township shall have the authority to order the suspension
of timber harvesting operations until the danger subsides.
The landowner and/or operator shall be responsible for repairing
any damage to public or private roads and other infrastructure caused
by traffic or equipment utilized for a timber harvesting, tree harvesting
or logging operation. At the discretion of the Board of Supervisors,
the landowner or operator shall furnish financial security or a bond
in an amount determined by the Township Engineer in order to guarantee
the repair of such damages in accordance with Title 67 Pa. Code, Chapter
189.
The landowner and/or operator shall clean any mud or debris
