B. 
Steep slopes. In areas of steep slopes, i.e., those above 25%, the following standards shall apply:
(1) 
No more than 50% of such areas shall be developed and/or regraded or stripped of vegetation.
(2) 
A geotechnical report shall be submitted with the earth disturbance plan, which report shall document load-bearing capacities, soil stability and interim and long-range erosion and sedimentation control measures.
(3)

D. 
No structure or manufacturing or processing activity or storage of materials shall be permitted in the buffer yard.
E. 
All buffer yards shall include a dense screen planting of trees, shrubs or other plant materials, or both, to the full length of the lot line to serve as a barrier to visibility, airborne particles and glare. Such screen planting shall be in accordance with the following requirements:
(1) 
All buffer yards shall be planted with shrub and tree plantings and/or installed with walls/fencing as permitted by this chapter in a pattern that creates no less than 20% transparency, unless otherwise specified by this chapter. Plant materials used in buffer yards shall be at least three feet in height when planted, shall be planted no more than three feet apart, and be of such species as will produce within three years a complete year-round visual screen of at least six feet in height. Trees that are used in the planting of a buffer yard and elsewhere on the lot shall be in accordance with Township standards. In addition, grass or ground cover shall be planted on the ground surface of the buffer yard. Buffer yards shall be maintained and kept free of all debris and rubbish.
(2) 
The screen planting shall be maintained permanently, and any plant material which does not live shall be replaced within one year.
(3) 
The screen planting shall be so placed that, at maturity, it will not overhang any street or property line.
(4) 
In accordance with the provisions of § 400-19, a clear sight triangle shall be maintained at all street intersections and at all points where private accessways intersect public streets.
(5) 
The screen planting shall be broken only at points of vehicular or pedestrian access.
(6) 
Buffer width and planting material shall be laid out to respect existing or proposed off-site uses. The minimum width may be used where compatible single-family uses adjoin or where the property abuts nonbuildable land. The object of the planting shall be defined in the plan as visual screening or to prevent access to hazardous areas.
(7) 
Where hazardous conditions exist, hedgerow planting shall be provided to make access difficult.
(8) 
Where the buffer yard width is less than the required building setback, self-maintaining ground cover or grass shall be planted to the edge of the buffer yard.
F. 
Screening.
(1) 
A planted visual barrier or landscape screen shall be provided and maintained on any property in a commercial, industrial or special district which is contiguous to any residential district, except where natural or physical barriers exist which are deemed adequate by the Planning Commission, and except where such contiguity has resulted from an amendment to the zoning district boundaries after the passage of this provision. This screen shall be composed of plants and evergreen trees arranged to form both a low-level and a high-level screen. The high-level screen shall consist of evergreen trees planted to a height of six or more feet and planted at intervals no greater than 10 feet. The low-level screen shall consist of shrubs or hedges planted at an initial height of not less than two feet and spaced at intervals of not more than five feet. A low-level screen shall be placed in alternating rows to produce a more effective barrier.
(2) 
Any part or portion of the site which is not used for building, other structures, loading or parking spaces and aisles, sidewalks and designated storage areas shall be planted and maintained with an all-season ground cover and shall be landscaped with trees and shrubs in accordance with an overall landscape plan and shall be in keeping with natural surroundings. Any off-street parking area with five or more spaces shall retain at least 5% of the total parking area for landscaping and shall be graded for proper drainage and paved, or at least one shade tree of at least two-inch caliper shall be provided per five parking spaces, or portions thereof, within the parking area, the grouping or spacing of which shall be reviewed as part of the landscape plan.
(3) 
Any off-street parking area located in a required front yard shall be set back at least five feet from the road right-of-way, with the area between the right-of-way and parking maintained with mulch, gravel or other appropriate ground cover and landscaped with trees, shrubs or boulders and in accordance with the landscape plan. In lieu of landscaping the above five feet, the applicant may elect to similarly landscape only that area between the road shoulder or berm and the right-of-way line.
Those standards for the control of odorous emissions established by the Allegheny County Department of Health shall be applied in all zoning districts. Where an odor is deemed offensive, a duly authorized Township representative shall refer the matter to the County Health Department.
A. 
No highly flammable, explosive or toxic liquids, solids or gases shall be stored, except as certified by the Allegheny County Fire Marshal and permitted by the Pennsylvania Department of Environmental Protection.

All organic rubbish or storage shall be contained in airtight, verminproof containers, which shall also be screened from public view.
D. 
No materials or wastes shall be deposited upon a lot in such form or manner that they may be transported off the lot by natural causes or forces; nor shall any substance which can contaminate wells, watercourses, or potable water supplies otherwise render such wells, watercourses, or potable water supplies undesirable as sources of water supply or recreation; nor shall any substance which will destroy aquatic life be allowed to enter any wells, watercourses, or potable water supplies.
