4. 
Protection Of Streets/property. No excavation shall be made so close to the property line to endanger any adjoining public or private street without supporting and protecting such public or private street or property from settling, cracking or other damage.
5. 
Fill/location. No fill shall be made so as to cause or to allow the same to be deposited upon or to roll, flow or wash upon or over the premises so affected; or upon or over any public street, walk, place or way; nor so close to the top of a bank of a channel as to create the possibility of bank failure and sliding. At a minimum, a setback of twenty-five (25) feet shall be provided as a buffer to sensitive areas.
6. 
Materials. Materials for fills shall consist of material obtained from excavation of cut areas, borrow pits or other approved source. Material shall be free of vegetable matter and deleterious material and shall not contain rocks in excess of six (6) inches in diameter, where compacted by rollers or other mechanical equipment. Materials for roadways are not covered by this Chapter as per exception in Section 530.030 hereof.
7. 
Minimum Standards. Minimum standards of excavations and fills shall be as follows; however, more stringent standards may be required based on site conditions:
a. 
No cut slope shall be made with a cut face steeper in slope than three (3) horizontal to one (1) vertical, unless the material in the excavated face is stable at a steeper slope as determined by experience for similar materials under comparable conditions and so certified by an experienced registered soils engineer.
b. 
No fill shall be made which creates an exposed embankment face steeper in slope than three (3) horizontal to one (1) vertical. The embanked end of the fill shall be uniformly compacted as provided in Subsection (8) hereof and stable under the proposed conditions. If a steeper slope is proposed, its stability shall be certified by an experienced registered soils engineer.
c. 
Sediment and erosion control plans for sites that exceed twenty thousand (20,000) square feet of grading shall provide for sediment or debris basins, silt traps or filters, staked straw bales or other approved measures, as set forth in the "City of St. Peters, Missouri Standards for Erosion and Sediment Management Practices", to remove sediment from runoff waters. The grading, sediment and erosion control plans and maintenance schedule are to be approved by the City Engineer or his/her designee. Temporary siltation control measures (structure) shall be maintained until vegetative cover is established at a sufficient density to provide erosion control on the site. (Refer to the City of St. Peters, Missouri Standards for Erosion and Sediment Management Practices.)
d. 
Where natural vegetation is removed during grading, vegetation shall be re-established in such a density as to prevent erosion. Permanent type grass must be established as soon as possible or during the next seeding period after grading has been completed. (Refer to the City of St. Peters, Missouri Standards for Erosion and Sediment Management Practices.)
e. 
Temporary re-vegetation, shall be established no later than fourteen (14) calendar days from the completion or suspension of grading operations, to provide erosion control on the site. Temporary re-vegetation shall be provided according to the most current edition of the City of St. Peters, Missouri Standards for Erosion and Sediment Management Practices, or recommendations of the City Engineer or his/her designee. (Refer to the City of St. Peters, Missouri Standards for Erosion and Sediment Management Practices.)
f. 
The adjoining ground to development sites (lots) shall be provided with protection from accelerated and increased surface water, silt from erosion, and any other consequences of erosion. Runoff water from developed areas (parking lots, paved sites and buildings) above the area to be developed shall be directed to diversions, detention basins, concrete gutters and/or underground outlet systems. (Refer to the City of St. Peters, Missouri Standards for Erosion and Sediment Management Practice.)
g. 
Development along natural watercourses shall have residential lot lines, commercial or industrial improvements, parking areas or driveways set back a minimum of twenty-five (25) feet from the top of the existing stream bank. The watercourse shall be maintained and made the responsibility of the subdivision trustees or in the case of a site plan the property owner. Permanent vegetation should be left intact where practical. Variances may include designed streambank erosion control measures and channel realignments and shall be approved by the City Engineer or his/her designee. Federal Emergency Management Agency (FEMA) and U.S. Army Corps of Engineers guidelines shall be followed where applicable regarding site development areas designated as floodplains and wetlands.
h. 
All lots shall be seeded and mulched, or sodded as specified in the City of St. Peters, Missouri Standards for Erosion and Sediment Management Practices before an occupancy permit shall be issued except that a temporary occupancy permit may be issued by the Building Department in cases of undue hardship because of unfavorable ground conditions.
8. 
Compaction. All fills intended to support buildings or structures or sewers and conduits shall be compacted to a minimum of ninety percent (90%) compaction as determined by Modified Proctor, ASTM D-1557, unless a lesser percent is recommended to and approved by the City Engineer or his/her designee. Compaction of greater than ninety percent (90%) may be required where special conditions dictate (i.e., large structures, dams). Compaction of fills for buildings or structures must be certified by a registered professional engineer. Compaction of other fills shall be required where necessary as a safety measure to aid in preventing the saturation, slipping or erosion of the fill. The requirements of the City Engineer or his/her designee for the compaction of fills shall include, but shall not be limited to, the following:
a. 
Areas to be graded by cutting or filling shall be rough graded to within two-tenths (2/10) of a foot of accepted elevation after allowance has been made for thickness of topsoil, paved areas and other installations.
b. 
The natural ground surface shall be prepared by removing topsoil and vegetation and by compacting the fill upon a series of terraces. Hillside or slope fills shall require plowing or scarification of original ground.
c. 
Grading on slopes will require silt control at intermediate levels, as outlined in the City of St. Peters, Missouri Standards for Erosion and Sediment Management Practices, to slow surface water, prevent rutting and decrease erosion.
d. 
Grading sites will require silting basins as outlined in the City of St. Peters, Missouri Standards for Erosion and Sediment Management Practices or other approved silt control to prevent mud from washing onto adjacent properties.
e. 
If fill material moisture content is below the requirement for compacting to maximum practical density, water in the proper amount shall be added. If moisture content is too great, fill material shall be aerated by blading or other satisfactory methods to reduce moisture content.
f. 
Frozen materials or soft, mucky, friable, easily compressible materials shall not be incorporated in fills intended to support buildings, structures, sewers or conduits, or in the embanked ends of fills. Fill material shall not be placed, spread or rolled while the ground is frozen or thawing.
g. 
The maximum uncompacted thickness of layers of the fill to be compacted shall not exceed eight (8) inches.
h. 
Compaction shall be by tamping, sheeps foot rollers, multiple wheel pneumatic or other approved methods. Rolling shall be continuous until the desired maximum density is obtained.
i. 
Density of the proposed fill(s) shall be submitted with the grading permit application for approval by the City Engineer or his/her designee.
j. 
Topsoil disturbed by grading or building operations if stripped and piled for storage shall be stored only in an amount necessary to complete finished grading.
9. 
Removal Of Timber, Rubbish, Etc. Timber, logs, trees, brush, vegetable matter and rubbish of any description shall be removed and disposed of so as to leave the disturbed area with a neat and finished appearance. Tree stumps, masonry and other obstructions shall be removed to the following depths:
