A.
Plans showing original and finished center-line profiles,
typical cross sections and proposed drainage facilities shall be submitted
to the Village and the Village Engineer before final subdivision plat
approval can be given. No construction shall be commenced until approval
of the plans has been given. After approval, the Village Engineer
shall be furnished with three sets of plans. After construction and
before acceptance, the Village Engineer shall be furnished with three
sets of as-built plans.
B.
In the case of street improvements initiated by the
Village, plans will be furnished by the Village.
A.
General. The roadway shall be graded to subgrade by
making cuts and fills to approved elevations. The fill material may
consist of material from the excavated areas after removal of all
boulders, topsoil, stumps, roots or other deleterious material or
from approved borrow pits.
B.
Stripping. Prior to the commencement of excavation
or filling, stripping shall be conducted to remove all topsoil, stumps,
roots, organic matter or other deleterious material for the full width
of the road section. Stripping is not required under fills where the
original grade is more than five feet below finished center-line grade
if the material is sufficiently stable, as approved by the Village
Engineer. Unacceptable material includes peat, muck and similar organic
materials subject to consolidation.
C.
Excavation. The excavation shall be executed in a
workmanlike manner, keeping the ditch lines below the cut section
to provide positive drainage at all times throughout the excavating
operation. The surface of the cut section will be left crowned after
each day's operation to ensure positive drainage away from the subgrade.
The surface of the subgrade shall be free from rocks with any dimension
in excess of six inches and other undesirable materials. The subgrade
in the cut section will be subject to test rolling as hereinafter
described.
D.
Embankment.
(1)
The material for embankment shall come either from
the cuts or approved borrow pits. The material shall consist of natural
soil, free from rocks, in excess of six inches, topsoil, stumps, roots
or other deleterious material and shall be of such gradation and moisture
content that it is capable of being compacted to the required density.
The embankment shall be built in a workmanlike manner. No embankment
shall consist of or be placed on frozen earth. Embankment shall be
placed in horizontal layers, not thicker than six inches after compaction
and of such cross section as to permit proper drainage. Proper compaction
is defined as an embankment which does not weave, rut or displace
in any manner under three consecutive passes of a ten-wheel (three-axle)
self-propelled dump truck loaded to the maximum legal load travelling
at a maximum speed of five miles per hour.
(2)
No stones over six inches in maximum dimension will
be allowed in the embankment closer than four feet to center-line
finished grade. No stones over three inches in maximum dimension will
be allowed between four feet and the finished grade in the embankment.
E.
Preparation of subgrade. The subgrade shall be constructed
to the cross sections and grades shown on the approved plans. The
Village Engineer shall be notified at least five days prior to the
placing of the base course above the subgrade. He or his agent will
be present and the entire roadway shall be tested for proper compaction
as heretofore defined. Any areas in either cut or fill which weave,
rut or distort shall be repaired until they do not weave, rut or distort.
When the subgrade is satisfactory to the Village Engineer, he will
issue a written approval. No base course shall be placed above subgrade
until this written approval is obtained.
F.
Culverts and subsurface drainage.
(1)
All underground utilities, culverts and storm sewers
shall be installed prior to placing the base course. The utilities
placed under the pavement limits shall be backfilled with a granular
material compacted to 95% density in accordance with ASTM D1557. All
culverts crossing the center line of the roadway shall be of a size
18 inches in diameter or larger. The material for all pipes shall
conform to the NYSDOT Specifications and shall be installed according
to the manufacturers specifications. Where catch basins or manholes
are called for, they shall be constructed in accordance with Village
standards. Manufacturer's certificates that all pipes meet these specifications
shall be given to the Village Engineer, if requested, before final
acceptance of the road. All pipes must be laid so that they have positive
drainage as shown on the approved plans.
(2)
The underdrain shall be six inch steel perforated
pipe meeting the NYSDOT Specifications. The pipe shall be installed
with the perforated holes on the bottom and shall be surrounded by
a minimum of six inches of filter material consisting of one part
concrete sand, one part No. 1 stone and one part No. 2 stone uniformly
mixed together, or material conforming to the NYSDOT Specifications
for underdrain filter materials. The flow line of the underdrain shall
be a minimum of 12 inches below subgrade at the edge of the gutter
and must drain to a positive drainage system.
(3)
All pipes and drainage structures are to be protected
and maintained and, if necessary, be cleaned, repaired or replaced
before final acceptance. The alignment and grades of all piping is
subject to inspection and approval by the Village Engineer.
G.
Base course. Before any base-course material is placed
on the subgrade, the subgrade shall be prepared and approved as described
heretofore. At any time that the subgrade becomes rutted or out of
shape ahead of the placing of the base course, it shall be reshaped
and sealed before any base material is placed upon it.
(1)
Material. The material acceptable for this course
shall be crushed stone complying with NYSDOT Specifications, and as
follows:
(a)
All particles shall pass a three-inch-square
hole, not less than 30% by weight shall pass the one-fourth-inch sieve,
not more than 35% by weight shall pass the No. 40 mesh sieve, and
not more than 10% by weight shall pass the No. 200 mesh sieve as determined
by washing through the sieve in accordance with ASTM Designation D422.
The particles retained on the one-fourth-inch sieve shall have a loss,
after four cycles of the magnesium-sulfate soundness test, not exceeding
30% by weight.
(b)
The particles passing the No. 40 mesh sieve
shall have a maximum plasticity index of five.
(2)
Construction.
(a)
The material shall be spread so that no appreciable
segregation of particle sizes occurs. The material shall be placed
in horizontal layers not exceeding six inches in thickness after compaction,
with a total minimum depth of 12 inches. Compaction may be done with
approved vibrating compaction equipment, a flatwheel roller weighing
approximately 10 tons, rubber-tired rollers or equipment approved
by the Village Engineer. Each layer shall be compacted to at least
95% of the maximum density determined in accordance with ASTM D1557.
(b)
Before the pavement is placed on top of the
base course, samples of the base shall be taken under the direction
of the Village Engineer and tested by a testing laboratory approved
by the Village to determine that the material passes the gradation
and compaction requirements. Certification of results of these tests
shall be given to the Village Engineer before final acceptance. Any
material not meeting the specifications shall be removed and replaced.
No material shall be placed when either fill, material or previous
layer is frozen. In the event that any fill which has already been
placed on the subgrade shall become frozen, it shall be scarified
and recompacted or removed, to the approval of the Village Engineer.
(c)
The base course shall be placed to the full
width of the roadway, including the gutters as shown on the typical
street section.
(d)
An additional thickness beyond the required
12 inches may be ordered by the Village Engineer where the subgrade
is wet or consists of an unstable material. This may require the processing
or removal of unstable material prior to the placement of the base
course.
H.
Gutters. Gutters shall be installed in accordance
with the current requirements of the Village, as determined by the
Village Engineer. The construction of the gutters shall comply with
NYSDOT Specifications, Section 609.
[Amended 8-24-1982 by L.L. No. 4-1982]
I.
Surface course. After the base course is completed
to a tolerance of 1/2 inch in 10 feet as shown on the approved plans
and cross sections and sealed with a flat-wheel roller weighing approximately
10 tons and approved by the Village Engineer, the surface course shall
be applied. If the pavement is not placed immediately following the
installation of the base course and said base course becomes contaminated
with undesirable material, this material shall be removed and the
base course restored to proposed grade prior to proceeding with the
surface course.
[Amended 8-24-1982 by L.L. No. 4-1982]
(1)
Material. The surface course shall consist of two-course
bituminous-concrete plant mix complying with NYSDOT Specifications.
(2)
Construction. The bituminous-concrete plant mix shall
be placed with an approved spreader with the final thickness of two
inches for the binder and one inch for the top as shown on the typical
street section. Immediately following placing of the hot mix, it shall
be rolled with a flat-wheel roller weighing approximately 10 tons,
equipped with a device to keep the rollers wet so that no mix adheres
to the rollers. The rolling shall continue until the roller does not
leave any ruts or tracks. Bituminous-concrete pavement shall be crowned
to slope at 1/4 inch per foot. No bituminous-concrete paving shall
be done over a wet surface or when the temperature is below 50°
F. All bituminous-concrete pavement shall be subject to coring under
the direction of the Village Engineer. The cores shall be taken at
not more than five-hundred-foot intervals. Any core found to be more
than 1/8 of an inch short of the specified thickness shall be unacceptable,
and the area represented by it shall be covered with a layer of bituminous
concrete properly bonded, or the top course shall be removed and replaced.
A.
After completion of the pavement, the contractor shall
shape, topsoil and seed the area between the gutter and the property
line. Topsoil shall be placed at a minimum depth of four inches and
be free of any roots, stones or clay materials. Seeding shall be of
the following mix:

B.
Immediately following preparation of the seed bed,
five pounds of seed per 1,000 square feet shall be uniformly applied
by a mechanical spreader. The seed shall be raked lightly into the
surface and rolled with a light hand lawn roller weighing not more
than 100 pounds per foot of width. Seeded areas shall be sprinkled
with a fine spray in such a manner as not to wash out the seed. Seeding
shall be done on a still day and only with the approval of the Engineer.
A.
Rough grading must be completed before the construction
of any utilities is commenced.
B.
All work performed by the contractor will carry a
one-year guaranty. The guaranty period will commence at the date of
the written final approval.
C.
Inspection by the Village Engineer will be required
periodically and as noted in the specifications. The contractor will
be obligated to inform the Village Engineer of his progress prior
to the start of the following construction operations:
D.
If sufficient notice is not given and therefore the
proper inspection of each operation is not made, the Village has the
right to test the final pavement, or the base course, by making three
consecutive passes over the pavement with a ten-wheel, three-axle,
self-propelled dump truck with the maximum legal load, moving at a
maximum speed of five miles per hour. If the test results in any weaving,
rutting or displacement of the pavement, it will be considered as
unacceptable by the Village.
E.
Yard area. All yards facing on a public street shall be properly graded at the time of the street construction, consistent with the street grades as constructed and in accordance with Chapter 99, Zoning, of the Village of Manlius Code.
F.
Street grades. Street grades shall be a minimum of
1% and a maximum of 10%. All streets will be crowned at 1/4 inch per
foot. The aforementioned grades and slopes will be modified as required
to provide proper drainage and smooth and safe transitions at intersections.
G.
Construction equipment, excess cut material and field
offices must be removed from the site when the work is completed.
