[Ord. No. 1457 §110, 1-5-1999]
All improvements required under these regulations shall be constructed
in accordance with the specifications and under the supervision of
the official having jurisdiction in the manner prescribed below.
[Ord. No. 1457 §110.02, 1-5-1999]
Prior to the construction of the improvements referred to above,
the developer shall furnish the Planning and Zoning Commission with
a corporate surety performance bond running to the City of Versailles
or other security acceptable to the Planning and Zoning Commission
sufficient to cover the developer's proportion of the costs, as estimated
by the developer's consultant or subject to approval, as the case
may be, of any or all of the improvements required to be installed,
thereby to assure the actual construction and installation of such
improvements immediately after final approval of the final plat or
at a time and according to the requirements of the Planning and Zoning
Commission.
[Ord. No. 1457 §110.03, 1-5-1999; Ord. No. 16-002 §§1 — 2, 1-12-2016; Ord. No. 21-002, 2-10-2021[1]]
A.
Width
For Street Construction.
[Ord. No. 22-007, 4-12-2022]
1.
Residential. Streets shall have a minimum right-of-way width of forty
(40) feet and shall have a third layer in width of no less than twenty
(20) feet.
2.
Commercial. Streets shall have a minimum right-of-way width of fifty
(50) feet and shall have a third layer in width of no less than thirty
(30) feet.
B.
Sub-Grade
Preparation.
1.
The proposed road bed should have all vegetation and topsoil stripped
from the area down to suitable clay materials that can be graded and
compacted. Clearing shall consist of complete removal of all trees,
stumps, down timber, fencing, snags, brush, and any debris not consistent
with the clay. Debris should be disposed of at a proper site, and
should not be buried on site.
2.
The sub-grade shall be substantially uniform in density throughout
the entire width of the sub-grade. The sub-grade shall have a minimum
of eight (8) inches of two-inch base rock and four (4) inches of one-inch
base rock for residential streets and twelve (12) inches of two-inch
base rock and four (4) inches of one-inch base rock for commercial
streets. The road bed should be constructed in a manner to drain surface
water to the side ditches or curbs. All road beds should have a two
percent (2%) crown or three percent (3%) slope in corners with super-elevation
to allow for proper street draining.
3.
All sub-grade shall be rolled. The sub-grade shall be checked after
rolling for proper elevation requirements, sufficient material shall
be removed or added and compacted to bring the sub-grade to required
elevation and density. Density shall reach ninety-five percent (95%)
of maximum density. Sub-grade elevation must be within one-half (1/2)
inch of proposed grades.
4.
After density has been achieved the road bed shall be proof rolled
with a loaded tandem dump truck. The truck shall be loaded with no
less then fourteen (14) tons (28,000 lbs.). The proof roll shall be
performed by driving the truck up and down the road bed in its lowest
gear at a walking pace, moving across the road bed in several passes
to cover the entire road bed. The Street Commissioner shall observe
the road bed for deflection (movement) as the wheels pass over. Any
deflection of more then one (1) inch shall be addressed by removing
the soft area and bringing in suitable material that shall be graded
and compacted.
5.
Soft areas shall be removed to a minimum depth of eight (8) inches
for residential roads and a minimum depth of twelve (12) inches and
a maximum depth of twenty-four (24) inches for all roads. If the maximum
depth is reached that the sub-grade is still not suitable it may be
necessary to use geo-grid and shot rock to stabilize the area. Replacement
material should be installed in 6-inch lifts and compacted to ensure
a solid bed.
C.
Aggregate
Base Course.
1.
This work shall consist of furnishing and placing a graded aggregate
material over a prepared sub-grade and grading and compacting that
material in preparation for pavement.
2.
Material for this work shall conform to MODOT gradations and shall
be Type 1 or 5 aggregate base material and shall be crushed stone
that has been properly screened and graded.
3.
Material shall be placed on the prepared road bed and compacted to
a density of ninety-five percent (95%) of maximum density.
4.
Grading of the material should match the grade of sub-grade with
a crown of two percent (2%) and maximum slope of three percent (3%)
on super elevations. This should be checked after compaction is complete
and should be within one-fourth (1/4) inch of the proposed grade.
5.
After density has been achieved the aggregate shall be proof rolled
with a loaded tandem dump truck. The truck should be loaded with no
less than fourteen (14) tons (28,000 lbs.). The proof roll shall be
performed by driving the truck up and down the road bed in its lowest
gear at a walking pace, moving across the road bed in several passes
to cover the entire road bed. The Street Commissioner shall observe
the aggregate base for deflection (movement) as the wheels pass over.
Any deflection of more than one (1) inch shall be addressed by removing
the soft area and bringing in suitable materials that shall be graded
and compacted.
D.
Bituminous
Pavement.
1.
Bituminous pavement shall be placed on the prepared road bed by placing
mixture with a self-propelled asphalt paver and compacted with self-propelled
rollers capable of reaching desired compaction.
2.
Bituminous material shall conform to MODOT Section 401. It shall
consist of a final compacted 3-inch layer of Bituminous Base Course
(Bit Base) and a final compacted 2-inch layer of Bituminous Pavement-1
(BP-1). A tack coat shall be placed between the Bit Base lift and
the BP-1 lift with a material that conforms to MODOT specifications
for Tack Coat.
3.
The Bituminous pavement shall be placed with a self-propelled asphalt
paver and shall follow the crown and grade established by the aggregate
base course.
4.
Uniform compaction shall be achieved with a self-propelled roller
to a minimum density of ninety-two percent (92%) of theoretical maximum
specific gravity. Density can be tested using either an approved filed
gauge or by cutting cores and testing the cores.
E.
Concrete.
1.
Residential streets that are paved with concrete shall be no less
than six (6) inches in depth with concrete at a strength of four thousand
(4,000) to five thousand (5,000) psi, with one-half (1/2) inch rebar
placed two (2) foot on center.
2.
Commercial streets that are paved with concrete shall be no less
than eight (8) inches in depth with concrete at a strength of four
thousand (4,000) to five thousand (5,000) psi, with one-half (1/2)
inch rebar placed two (2) foot on center.

installed on each lot within the subdivision, provided that no individual
disposal devices shall be permitted unless the lots to be so served
have sufficient areas to allow adequate soil absorption area for on-site
sewerage disposal under potential adverse soil slope and subsurface
geology conditions. The Department of Natural Resources, with the
concurring approval of the Planning and Zoning Commission, may modify
lot area requirements in relation to soil conditions and other pertinent
facts and findings in any particular subdivision. All such individual
