[Adopted as Ch. 48 of the 1972 Code]
The following construction specifications and
standards are set forth for the guidance of those designing and/or
constructing facilities for developments or subdivisions in the Town
of Carmel.
These road specifications are not intended to
cover every detail of construction, but are adopted to indicate acceptable
standards of materials, workmanship and construction in a general
way.
In the interest of keeping this specification
small, reference is made to Public Works Specifications of January
2, 1962, as issued by New York State Department of Public Works, Division
of Construction, hereinafter referred to as "state specifications,"
and any changes, modifications or addenda thereto.
A.
Should the site become dusty, special treatment shall
be taken to prevent dust blowing about the neighborhood.
B.
Should mud and silt tend to wash off the project,
necessary steps shall be taken to catch it by screens, settling basins
or other means so that it will not cause inconvenience and maintenance
expense to the surrounding area, public roads and lands.
During construction, the developer will be required
to regulate and maintain traffic, post detours and do such work as
is called for on the plans or may be required by the consulting or
Town Engineer for the proper safeguarding and handling of all traffic.
A.
The approval of materials and methods of construction
shall, in general, be under the direction of the consulting or Town
Engineer.
B.
After approval of the subdivision plat by the Planning
Board, any variance from the standards set forth in these specifications
must be requested in writing to the consulting or Town Engineer by
the developer, and approval must be in writing by the consulting or
Town Engineer.
A.
Before any work described herein is undertaken, at
least 48 hours' written notice shall be given to the consulting or
Town Engineer.
B.
None of the operations required herein shall be backfilled,
covered or succeeded by a subsequent operation until approval is rendered
by the consulting or Town Engineer.
C.
Work performed not in accordance with these provisions
cannot be accepted.
A.
Whenever a developer, during the course of development
and before acceptance of any construction under the subdivision regulations
and road specifications of the Town of Carmel, encounters conditions
such as flood areas, underground water, springs, intermittent streams,
humus beds, unsuitable slopes, soft and soupy areas or other unusual
circumstances not foreseen in the general planning, such conditions
shall be reported to the Planning Board, together with the developer's
recommendations, if he so wishes, as to special treatment to secure
adequate and permanent construction.
B.
The consulting or Town Engineer shall, without unnecessary
delay, investigate the condition and either approve the developer's
recommendations to correct the same or a modification thereof or issue
its own specifications for the correction of the condition.
C.
Unusual circumstances or detrimental conditions observed
by the consulting or Town Engineer or its agents shall be similarly
treated.
The following specifications shall apply to
all roads hereafter constructed within the Town of Carmel except as
provided for herein and with the additional exceptions:
B.
Table I provides an outline of street design standards.[2]
[2]
Editor's Note: Table I is included at the end of this chapter.
A.
Intersections shall be constructed in accordance with
construction details. In the case of a new street intersecting an
existing narrow road, it shall be modified as indicated.
B.
Intersections shall be so designed as to provide a
minimum length of 100 feet at a ninety-degree angle at a grade not
to exceed 2%. Whenever a street approach intersects at an angle smaller
than 75°, special treatment as determined by the Planning Board
and islands to channelize traffic may be required. Design details,
at scale not less than one inch equals 20 feet, shall be prepared
indicating pavement grades and drainage details and the corresponding
cross sections. Table I indicates the general design and construction
standards to be applied.
Wherever a temporary or permanent dead end is
allowed on a subdivision street, a turnaround shall be constructed.
This turnaround shall take the form of a circle as indicated on construction
standards and Table I. Temporary types of construction shall be used
only when authorized by the Town Planning Board, because of the foreseeable
future extension of the street. The circular turnaround shall be completely
paved with no center island. Grades shall be limited to 5%, with a
minimum length of tangent of 150 feet.
A.
Streets shall be so designed that finished tangent
grades will not be less than 1% nor more than 8%.
B.
Every change in grade shall be effected with a vertical
curve of sufficient length to insure adequate stopping sight distance
and to provide for smooth transition. Vertical curves shall be designed
in accordance with Table I.[1]
[1]
Editor's Note: Table I is included at the end of this chapter.
A.
Rights-of-way between outside slope lines of ditches
or gutters shall be cleared of all trees, shrubs, stumps, buildings
or other structures and all unsuitable matter. Within the right-of-way
area, such perishable matter shall be removed to a depth of two feet
below finished grade. Stream channels, ditches and easement areas
shall be cleared and grubbed.
B.
On horizontal curves any additional width necessary
to maintain a minimum visibility of 350 feet at the paving edge shall
be cleared.
C.
The Planning Board may waive the clearing of certain
trees upon request or, upon its own initiative, may request certain
trees within the right-of-way to be preserved.
A.
The developer shall complete the shaping of the road
right-of-way, streams and ditches and easement areas to the line and
grade shown on the approved plan and as otherwise may be directed
by the Town Engineer. All unsuitable or unstable materials shall be
completely excavated and removed from the right-of-way, and all rocks
or boulders larger than six inches in diameter shall be excavated
at least eight inches below the finished subgrade or road pavement,
drainage or drainage structures, curbs and sidewalks.
B.
Where fills are necessary to complete the required
line and grade or to backfill trenches or other excavation, the materials
incorporated in the work shall be acceptable to the Town Engineer
and shall be placed in layers not exceeding six inches in depth, each
layer to be thoroughly compacted by rolling with three-wheel, sheepsfoot,
pneumatic tires or paddle wheel roller, or by impact rammer or vibrator
equipment in areas inaccessible to power rollers. All compaction shall
continue until the fills are firm and unyielding.
C.
The rough grade of the road pavement, curb and sidewalk
areas shall be completed to within one inch above or below finished
subgrade as shown on the approved cross section of the right-of-way
improvement.
D.
Earth shoulders and flow line of ditches and gutters
shall be maintained in satisfactory condition at the developer's expense
at all times during the course of construction of the subdivision
and until such time as the Town Board has accepted dedication of the
right-of-way.
A.
Before fine grading or construction of curbs and sidewalks
is started, all storm and sanitary sewers and all utilities, including
house connections and hydrants, shall have been installed, and all
fill and backfill shall have been thoroughly compacted to the satisfaction
of the consulting or Town Engineer.
B.
Also, before fine grading or construction of curbs
and sidewalks is started, all heavy trucking for building or site
construction purposes shall have been completed.
C.
After completion of the rough grade and prior to the
laying of the foundation course, the subgrade shall be shaped to line
and grade and thoroughly compacted with an approved self-propelled
roller weighing not less than 10 tons. All hollows and depressions
which develop under rolling shall be filled with acceptable granular
material and again rolled, this process to be continued until no depressions
develop. The subgrade shall not be muddy or otherwise unsatisfactory
when the foundation course is laid upon it.
D.
Any soft or unstable portions of the subgrade which
develop under the roller shall be completely excavated and removed
from the right-of-way and shall be replaced with acceptable granular
material and the area regraded and compacted as above.
E.
Fine grade shall conform to the prescribed width of
pavement and shall extend equidistant from the center line of the
road right-of-way and shall conform to the typical cross section of
the road pavement and to the approved line and grade.
A.
After the fine grade and all curbs have been constructed
to the satisfaction of the Town Engineer, the developer shall furnish
and place a foundation course of approved run-of-bank gravel, crusher-run
stone or crusher-run gravel, to the depths as called for in these
specifications. All materials acceptable for this course shall be
hard, durable and sound and shall be well graded from coarse to fine,
the maximum diameter of the large particles not exceeding 2/3 of the
thickness of the compacted foundation course, and 90% to 100% by weight
of the particles shall be of such size as will pass through a two-inch
square hole, not more than 70% by weight pass the No. 40 sieve and
not more than 10% by weight pass the No. 200 mesh sieve (Item 4, state
specifications).
B.
The materials shall be placed on the finished subgrade
by means of mechanical spreaders, motor graders, and shall be thoroughly
compacted by rolling with a self-propelled ten-ton roller. Water shall
be added to the materials in such amounts as the consulting or Town
Engineer may consider necessary for proper compaction. After compaction,
the course shall be true to grade and cross sections, and any depressions
shall be eliminated by the use of additional granular materials, thoroughly
rolled in place. In all cases, the foundation course must be so thoroughly
compacted that it will not weave under the roller.
A.
Bituminous penetration macadam base course.
(1)
After the foundation has been completed as previously
described and to the satisfaction of the consulting or Town Engineer,
the bituminous penetration macadam base course shall be constructed.
Crushed stone not over two inches shall be spread by means of an approved
mechanical spreader in such quantities that after being compacted
with a ten-ton roller the thickness of the course shall not be less
than four inches. It is imperative that this course conform accurately
to the line, grade and cross section specified and as called for on
the plans and on the typical cross section. Necessary pins, lines,
grades and other control devices shall be set in order to attain the
desired accuracy. To prevent the displacement of the edges of the
pavement during rolling and also to furnish a gauge for the depth
of stone, shoulders of selected material shall be first constructed.
The rolling shall begin at the edges of the pavement and proceed towards
the center. It is important that the rear wheel of the roller first
lap the shoulder and stone edge about 1/2 the width of the roller
and that the succeeding trips of the roller shall similarly overlap
and produce a condition where there is no creeping or waving under
the roller and no smearing or breaking down of the stone. The exactness
of the rolled surface should be tested by applying a ten-foot-or-longer
straightedge longitudinally. The sizes of aggregate specified for
the base course shall approximate the following gradation:

(2)
The stone shall be rolled with a ten-ton roller until
well keyed in preparation for the application of the bituminous binder
as directed by the inspector.
(3)
The bituminous material shall be applied by means
of a pressure distributor at a rate of not less than 1.75 gallons
per square yard. The bituminous material shall be 85-100 or 100-120
penetration paving asphalt or as may be specified by the consulting
or Town Engineer. Immediately after the application of the first coat
of bituminous material, clean five-eighths-inch or one-half-inch dry
key or filler stone shall be spread over the surface in sufficient
quantities to completely fill the voids in the penetrated surface.
Care should be exercised to avoid an excess of stone. The key stone
should be spread by a suitable spreading device attached to a truck.
Hand brooms or a broom drag should be used to provide a smooth, even
distribution of key stone after it has been rolled sufficiently to
bind the stone into the penetrated base course.
(4)
Following this, a second application of bituminous
materials is made at the rate of 0.50 gallons per square yard, the
same asphalt cement being used in a like manner as for the first application.
A covering of clean, dry, three-eighths-inch stone is then spread
uniformly over the surface of the second coat of asphalt cement in
a similar manner as the key stone was applied. An excess of stone
must be avoided. This is then rolled and followed by brooming, with
further rolling taking place. The surface may be open to traffic as
soon as the final rolling and brooming is completed.
B.
Asphaltic concrete base course. In lieu of the above,
an asphaltic base course equivalent to the New York State Department
of Public Works Specifications Item 45SN shall be placed by mechanical
means to a compacted depth of not less than three inches.
A.
After the base course has been completed to the satisfaction
of the consulting or Town Engineer, a two-course bituminous concrete
wearing course shall be constructed conforming to the New York State
Department of Public Works Specifications of 1962 for Item 51M, Asphaltic
Concrete.
B.
After the base course has been thoroughly cured and
cleaned of all foreign material, a bituminous concrete mechanical
spreader with tamping bars and heating unit in sufficient depth as
to provide a finished compacted thickness after rolling of not less
than 1 1/2 inches. The course in place shall be thoroughly rolled
with a ten-ton roller.
C.
After the binder course has been completed and thoroughly
cleaned of foreign material and a tack coat of asphalt emulsion applied
to the surface at the rate of 1/10 to 1/20 gallons per square yard
in the event that the binder course has been subject to traffic for
an extended period of time, a final wearing course of fine bituminous
concrete shall be uniformly spread by a self-propelled mechanical
spreader equipped with tamping bars and heating unit and in sufficient
depth as to provide a finished compacted thickness after rolling of
not less than one inch. The fine wearing course in place shall be
thoroughly compacted with a two- or three-tandem roller weighing approximately
10 tons.
D.
Extreme care shall be exercised in the placing of
bituminous concrete to ensure that all longitudinal joints shall be
lapped in the placing of adjoining strips and that all lateral joints
are trimmed before continuing with the placing of additional materials
on that strip.
E.
No paving will be permitted after October 15 of each
year, except with written permission of the consulting or Town Engineer.
Under no circumstances shall material be placed when the surface temperatures
are below 40° F. or the weather inclement.

Roads which are to be dedicated to the Town
of Carmel through a road improvement district shall be improved to
the following standards as part of the dedication process:
A.
Minimum width of traveled way shall be 18 feet. Culs-de-sac
will be 90 feet in diameter unless documentation is received from
the applicable school district indicating that they will not be providing
bus service on the road offered for dedication. In that case, the
cul-de-sac may be reduced in size or eliminated as determined by the
Town Engineer and the Highway Superintendent.
B.
Width of the right-of-way shall be 50 feet. Widths
less than 50 feet will be considered on a case-by-case basis and upon
approval of the State Commissioner of Transportation except that in
no case shall the width of right-of-way be less than 25 feet.
D.
The exact depth can be adjusted based upon the existing
surface, provided the total depth of pavement is five inches and base
is six inches, minimum.
E.
Existing drainage conditions will be evaluated on
a case-by-case basis by the Town Engineer and Highway Superintendent
to determine the extent of improvements necessary.
