The applicant, in any activity requiring a permit,
and which involves 10 or fewer single-family residences, after commencing
initial operation, shall request inspection by the Township Engineer:
A. Upon completion of stripping, the stockpiling of topsoil
and disposal of all unsuitable material, but prior to beginning any
other preparation of the ground.
B. Upon completion of preparation of ground to receive
fill, but prior to beginning any placement.
C. Upon completion of rough grading, but prior to placing
topsoil, permanent drainage or other site-development improvements
and ground covers.
D. Upon completion of final grading, permanent drainage
and erosion control facilities, including established ground covers
and planting, and all other work of the permit.
The applicant, in all other cases other than that referred to in §
159-23, after commencing initial operations, shall request inspections by the Township Engineer at the following stages in the development of the site, or of each subdivision thereof:
A. Prior to commencement of grading operations to determine
suitability of all proposed fill materials.
B. Upon completion of stripping, the stockpiling of topsoil
and disposal of all unsuitable material, but prior to beginning or
any other preparation of the ground.
C. Upon completion of preparation of ground to receive
fill, but prior to beginning or placement, an inspection of proof
rolling.
D. Upon completion of structural fill, placement such
that the following earth-fill procedures are assured:
(1) Prior to placing fill in any area, grading should
be performed as required to provide for drainage. Ditching or filling
around the area should be performed to intercept or divert all surface
water. Within the area on which fill is to be placed, the ground should
be graded so as to provide for unobstructed drainage from every point
to some disposal point.
(2) The area should be closely examined to determine whether
excessive wetness, springs or other seepage of water can be observed.
If such conditions exist, drainage must be provided before placement
of fill is undertaken.
(3) When the fill area has been prepared, as specified,
the existing ground surface should be compacted by the specified method
for compacting fill.
(4) Fill should begin at the lowest section of the area.
Fill should be spread in six-inch layers prior to compaction. Each
layer should be approximately horizontal, but small slopes can be
permitted in order to provide for surface water runoff.
(5) Each layer of fill should be inspected prior to compaction.
All roots, vegetation or debris should be removed. Stones larger than
six inches in diameter should be removed or broken. The moisture content
of each layer should be determined to be suitable for compaction.
(6) The compaction of the fill should be done with a sheepsfoot
roller, rubber-tired roller or a vibratory roller. Other compaction
equipment should be used only after it has demonstrated that satisfactory
results can be obtained with it.
(7) Each layer of compacted fill should be tested to determine
its dry density as per ASTM D 1556. The density of each layer should
be not less than 95% of maximum dry density as determined by ASTM
D 1557. The moisture content of the compacted layer should be not
more than 4% less nor 2% greater than the optimum moisture as determined
by ASTM D 1557.
(8) Only when the compacted layer has been shown to be
as specified should other layers of fill be placed above it.
(9) Visual inspection of borrow material should be made
periodically to assure that no variation in the fill material has
occurred.
E. Upon completion of rough grading, but prior to placing
topsoil, permanent drainage or other site development improvements
and ground covers.
F. Upon completion of trench backfilling operations so that testing can be performed as specified in Subsection
D.
G. Upon completion of final grading, permanent drainage
and erosion control facilities, including established ground covers
and planting, and all other work of the permit.
