The following shall be minimum standards for issuance of a land disturbance permit:
A. 
The maximum slope of an excavation shall be 1 1/2 horizontal to one vertical. The maximum slope for fill shall be two horizontal to one vertical; provided, however, that the maximum cut may be increased to one horizontal to one vertical where a professional geotechnical engineer certifies that the cut shall be into sedimentary rock or other material which is sufficiently durable to remain stable and maintain the cut without slippage. The only exception to this standard shall be where a retaining wall, designed and sealed by a professional engineer, is constructed to support the face of the slope.
B. 
No grading, excavation or fill shall be performed in proximity to any property line as to endanger or damage any adjoining street, public or private property without protecting such property from settling, cracking, erosion, sedimentation, flooding or any other physical damage or personal injury which might result.
C. 
Excavation adjacent to building foundation walls, footings or structures shall not extend beyond the angle of repose or natural slope of the soil under the nearest point of the same unless the footings, foundations or structures have been sufficiently underpinned or otherwise protected against settlement.
D. 
Adequate provisions shall be incorporated to prevent erosion due to storm drainage. Existing storm drainage shall not be diverted so as to alter the location of watercourses on any adjacent property. All storm drainage facilities must be in conformance with Chapter 319, Stormwater Management, and reviewed and approved by the Municipality.
E. 
No debris or other material shall be placed or be allowed to accumulate in any drainage ditch or structure in such a manner as to obstruct the free flow of surface water.
F. 
Trees shall not be removed unnecessarily.
G. 
Provisions shall be made for dust control as are deemed necessary and approved by the Municipality.
H. 
All fill shall be compacted to provide stability of fill materials and to prevent settlement or slippage. Any fill material to be used shall be tested by the owner to ensure that its dry density shall be not less than 92% of maximum density as determined by ASTM D1556 or other appropriate standard based upon the type of material involved and with approval of the Municipality.
I. 
Immediately upon completion of grading, all areas not designated for building or paving shall be mulched and planted in accordance with the approved erosion and sedimentation control plan for the site and/or current PADEP regulations.
J. 
Plans and specifications shall provide for both temporary and permanent erosion and sediment control.
K. 
When needed for slope stabilization, benching shall be required in accordance with the latest edition of the "Erosion and Sediment Control Best Management Practice Manual, Technical Guidance Number 363-2134-008," PADEP.
L. 
Topsoil stripped from the site in preparation for earth-moving activities shall be stockpiled and replaced on the site over all regraded, nondeveloped areas, at a minimum depth of four inches.
M. 
Any work proposed in an area of landslide-prone soils shall be designed, signed and sealed by a professional geotechnical engineer.
N. 
Fill areas shall be prepared by removing organic material, other material not defined as clean fill, and any other material determined by the Municipality that would prevent proper compaction and stability.
O. 
In addition to the above, all fill and cut operations shall follow the "Erosion and Sediment Control Best Management Practice Manual, Technical Guidance Number 363-2134-008," PADEP. A soil and erosion and sedimentation plan shall be prepared in accordance with the provisions of Title 25, Environmental Protection, Chapter 102, Erosion and Sediment Control,[1] and approved by the Allegheny County Conservation District (ACCD) prior to the commencement of any grading or other regulated earth-disturbance activity, unless the ACCD determines that a soil and erosion control plan is not required.

Editor's Note: See 25 Pa. Code Chapter 102.
P. 
Grading activity near a stream, creek, river, wetland or other body of water shall be in accordance with PADEP and Chapter 359, Zoning, regulations.
Q. 
No grading shall occur in landslide-prone areas or areas exceeding 30% in slope unless designed, signed, and sealed by a professional geotechnical engineer.
R. 
Grading must not create or contribute to landslides, accelerated soil creep, settlement and subsidence or hazards associated with strong ground motion and soil liquefaction.
S. 
Grading must not create or contribute to flooding, erosion, or increased turbidity, siltation or other form of pollution in a watercourse.
A. 
Retaining walls shall be designed and constructed in accordance with sound engineering practice and the current edition of the Pennsylvania Uniform Construction Code (PAUCC). The design of any proposed retaining wall shall be included in the application for a land disturbance permit.
B. 
A professional engineer, registered in the Commonwealth of Pennsylvania, shall design all retaining walls greater than four feet in height, and the plans submitted for approval shall bear their seal and signature.
C. 
Where a retaining wall is to be constructed, the vertical face of the wall shall be at least five feet from any adjoining property.
Equipment shall not cross live streams. Provisions shall be made for the installation of culverts or bridges for such crossings. The applicant shall be responsible for obtaining any permits required by the Pennsylvania Department of Environmental Protection for temporary and permanent encroachments, relocations, enclosures, and temporary stream crossings. A copy of the permit(s) must be submitted to the Municipality.
All land disturbance work within designated or known floodplains shall conform to the requirements and standards of Title 25 of the Commonwealth of PA Code Chapter 105, Environmental Protection, Dam Safety and Water Management, and Title 25 of the Commonwealth of PA Code Chapter 106, Floodplain Management, and Chapter 359, Zoning, of the Code of the Municipality of Monroeville.
