In expansion of the statement of community development objectives found in Article I, § 350-5, of this chapter, the specific intent of the SS Steep Slope Conservation District shall be to conserve and protect those areas having steep slopes, as defined herein, from inappropriate development and excessive grading, as well as to permit and encourage the use of said areas for open space purposes, so as to constitute a harmonious aspect of the continuing physical development of Upper Pottsgrove Township. In implementing these principles and the general purposes of the Comprehensive Plan and this chapter, the following specific objectives are intended to be accomplished by the adoption of the Steep Slope Conservation District:
A.
To combine with other zoning requirements, as an overlay,
certain restrictions for steep slope areas to promote the general
health, safety, and welfare of the residents of Upper Pottsgrove Township.
B.
To prevent inappropriate development of steep slope
areas in order to avoid potential dangers for human usage caused by
erosion, stream siltation, soil failure leading to structural collapse
or damage and/or unsanitary conditions and associated hazards.
C.
To minimize danger to public health and safety by
promoting safe and sanitary drainage.
D.
To permit only those uses that are compatible with
development of steep slope areas in order to avoid accelerated erosion,
soil failure, accelerated seepage or other conditions which may create
a danger to life and/or property.
E.
To permit only those uses in steep slope areas that
are compatible with the preservation of existing natural features,
including vegetative cover, by restricting the grading of steep slope
areas.
F.
To promote the ecological balance among those natural
system elements (such as wildlife, vegetation and aquatic life) that
could be adversely affected by inappropriate development of steep
slope areas.
G.
To prevent development that would cause excessive
erosion and a resultant reduction in the water-carrying capacity of
the watercourses which flow through or around the Township with the
consequences of increased flood crests and flood hazards within the
Township and to both upriver and downriver municipalities.
H.
To protect individuals and adjacent landowners in
the Township and/or other municipalities from the possible harmful
effect of inappropriate grading and development on steep slope areas.
I.
To protect those individuals who choose, despite the
cited dangers, to develop or occupy land with steep slopes.
J.
To protect the entire Township from inappropriate
development of steep slope areas, which could have an effect upon
subsequent expenditures for public works and disaster relief and thus
adversely affect the economic well-being of the Township.
K.
To promote the provision of safe and reliable accessways,
parking areas and utility systems serving development on or around
steep slope areas, where more sensitive grading and siting is essential.
L.
To assist in the implementation of pertinent state
laws concerning erosion and sediment control practices, specifically
Chapter 102, Erosion Control, of the Clean Streams Law, P.L. 1987,
35 P.S. § 691.1 et seq., and any subsequent amendments thereto,
as administered by the Pennsylvania Department of Environmental Protection
and the Montgomery County Conservation District.
[Amended 8-14-2000 by Ord. No. 310]
The boundaries of the SS Steep Slope Conservation
District are defined and established as all those areas of the Township
having a slope of 15% or more, referred to as "steep slopes" or "steep
slope areas."
A.
Any subdivision or land development plan shall show steep slope areas in accordance with Chapter 310, Subdivision and Land Development.
B.
The Township shall exempt man-made slopes from the
provisions herein, if it is determined that alteration, regrading,
clearing, construction upon such slopes will not be injurious to the
health, safety and welfare of the community. It shall be the burden
of the applicant to demonstrate that the steep slopes were man-made.
C.
The Township Board of Commissioners may require applicants
to revise the boundaries of the Steep Slope Conservation District
based on the accuracy of the applicant's plans as determined by the
Township Engineer.
D.
Area of steep slopes shall be plotted on the Zoning
Map, if feasible, to indicate the approximate boundaries of the SS
Steep Slope Conservation District.
E.
Changes in the boundaries of the SS Steep Slope Conservation
District shall be plotted, if feasible, on the Zoning Map as amendments
thereto.
The Steep Slope Conservation District shall
be deemed to be an overlay on any zoning district(s) now or hereafter
enacted to regulate the use of land in Upper Pottsgrove Township.
A.
The Steep Slope Conservation District shall have no
effect on the permitted uses in the underlying zoning district, except
where said uses intended to be located within the boundaries of the
Steep Slope Conservation District, as defined herein, are in conflict
with the permitted uses set forth in this article.
B.
In those areas of Upper Pottsgrove Township where
the Steep Slope Conservation District applies, the requirements of
the Steep Slope Conservation District shall supersede the requirements
of the underlying zoning district(s).
C.
Should the Steep Slope Conservation District boundaries
be revised as a result of legislative or administrative actions or
judicial decision, the zoning requirements applicable to the area
in question shall revert to the requirements of the underlying zoning
district(s) without consideration of this article.
D.
Should the zoning classifications(s) of any parcel
or any part thereof on which the Steep Slope Conservation District
is an overlay be changed, as a result of legislative or administrative
actions or judicial decision, such change(s) in classification shall
have no effect on the boundaries of the Steep Slope Conservation District,
unless an amendment to said boundaries was included as part of the
proceedings from which the subsequent change(s) originated.
An initial determination as to whether or not
the Steep Slope Conservation District applies to a given parcel shall
be made by the Zoning Officer.
A.
Any party aggrieved by the decision of the Zoning Officer, either because of an interpretation of the exact location of the Steep Slope Conservation District boundary or because the criteria used in delineating the boundary, as set forth in § 350-36 of this article, is or has become incorrect because of changes due to natural or other causes, may appeal said decision to the Zoning Hearing Board as provided in Article XIX of this chapter.
[Amended 11-26-1990 by Ord. No. 218]
In the SS Steep Conservation District the following
land use and development regulations shall apply:

compliance only if the building or premises and the proposed use thereof
conform with all requirements of this chapter.
The granting of a zoning permit or approval
of a subdivision or land development plan on or near the Steep Slope
Conservation District shall not constitute a representation, guarantee
or warranty of any kind by the Township of Upper Pottsgrove, or by
any official or employee thereof, of the practicability or safety
of the proposed use and shall create no liability upon Upper Pottsgrove
Township, its officials, or employees. The degree of erosion and sediment
control protection intended to be provided by this chapter is considered
reasonable for regulatory purposes and is based on engineering and
scientific methods of study. This chapter does not imply that areas
outside the Steep Slope Conservation District boundaries or land uses
permitted within said district will always be totally free from the
adverse effects of erosion.
