All land defined herein as having steep slopes shall be subject to the following regulations:
A.
Intent. It is the intent of this section to control the development of land in areas containing excessive topography for the following purposes:
(1)
To limit erosion and sedimentation;
(2)
To protect watersheds and limit increases in stormwater runoff;
(3)
To prevent an increase in the possibilities of landslides and soil subsidence;
(4)
To maintain adequate foliage cover on hillsides; and
(5)
To protect streams from increases in sediment pollution.
B.
Permitted uses. Steep slopes may be used as permitted by the district regulations within which they are located, subject to the additional requirements below.
C.
Principles of development. Wherever possible, structures and grading of land shall only be located on portions of a lot where the slope is less than 25%, as herein defined. However, where it is necessary to use steep slopes to permit development of a lot, all such proposals shall, in addition to other applicable regulations of this chapter, be in accordance with the following principles of development. All development on steep slopes shall:
(1)
Be oriented so that grading and other site preparations are kept to an absolute minimum;
(2)
Where grading is essential, shape such grading to complement the natural land form;
(3)
Be staged where necessary to complete construction of each stage during a season so that large areas of disturbed land are not left bare and exposed during the winter-spring runoff period;
(4)
Accomplish all paving as rapidly as possible after grading;
(5)
Allocate to open space and recreation uses those areas least suited to development, as evidenced by competent soils, geology, and hydrology investigations;
(6)
Landscape areas around structures to blend them with the natural landscape; and
(7)
Take measures to minimize erosion and sedimentation and to limit increases in stormwater runoff in accordance with other ordinances and regulations of this municipality and the laws and regulations of the Commonwealth of Pennsylvania.
D.
Site plan. All applications for zoning permits for lots, uses, and structures located, in whole or in part, on land with steep slopes shall submit, along with the application, a site plan as required by Article X of this chapter. Such application shall also include a stormwater management plan in accordance with Chapter 253, Stormwater Management, and a copy of the erosion and sedimentation control plan as required by the Pennsylvania Department of Environmental Protection.
