[HISTORY: Adopted by the Board of Trustees
of the Village of Pomona 1-18-1969; amended in its entirety 2-8-1988 by L.L. No. 1-1988. Subsequent amendments noted where
applicable.]
It is the purpose of these specifications to
establish minimum acceptable standards of street construction for
subdivisions in the Village of Pomona, including but not limited to
width, design, drainage, construction of base and pavement, curbs
and sidewalks, monuments and signs. Dedication of the right-of-way
will not be accepted until the developer's professional engineer and
the Village Engineer shall have certified to the Village Board in
writing that the construction of the street or streets has been completed
in accordance with the approval plans and the specifications which
follow.
In his written certification, as required above,
the developer's professional engineer shall state clearly that he
or his authorized representative has inspected all phases of the street
construction and that all work has been completed in accordance with
the approved plans and these specifications.
The plan of the proposed street shall be prepared
by a qualified engineer properly licensed by the State of New York.
The plan shall clearly define the limits of the proposed right-of-way
and shall include the location, widths, profiles and grades of proposed
roadways, storm drainage, including culverts and other drainage structures,
and the location of easements and utilities. The plan shall first
be submitted to the Village Engineer and then to the Planning Board
for review and approval under the applicable subdivision regulations
of the Village.[1] Such plans so submitted shall not be altered or amended
after having been approved by the Planning Board, unless amended plans
are resubmitted and approved as above. However, the developer shall,
at his own expense, provide additional storm drainage facilities as
may be ordered by the Village Engineer if, during the progress of
the work, in the opinion of the Village Engineer, such additional
structures or facilities are necessary to assure the durability of
pavement, the future maintenance of the right-of-way or the welfare
or safety of the public, except that the Planning Board may vary the
requirements of such order where there are practical difficulties
or unnecessary hardships in the way of carrying out the strict letter
of such order, unless such variance conflicts with the provisions
of a town or county official drainage map, in which event the official
map shall prevail. If construction has not been started within one
year from the date of final approval by the Planning Board, plans
shall be resubmitted and approved as above.
A.
Prior to the start of construction of any improved
street, the developer shall deposit with the Village Clerk a performance
bond of acceptable surety or shall deposit with the chief fiscal officer
of the Village acceptable negotiable government bonds, cash or certified
check or letter of credit drawn upon a national or state bank, payable
at sight to the Village Board, guaranteeing:
(1)
That within two years the developer will complete
all the construction within the right-of-way, including roadway, shoulders,
sidewalks, curbs, gutters, storm drainage, etc., and all utilities,
including hydrants and house connections for each lot, in accordance
with the approved plan and these specifications.
(2)
That, upon certification by the developer's professional
engineer and by the Village Engineer that the construction of the
street has been completed in accordance with the approved plans and
specifications, the developer will dedicate the completed street to
the Village for use as a public highway free and clear of all liens
and encumbrances. This guaranty of dedication shall apply to the owner
of the property as well as the developer where the two are not synonymous.
B.
As guaranty for the performance of the above requirements,
the developer shall deposit as heretofore set forth a surety bond,
letter of credit, negotiable government bond, cash or certified check,
the minimum total amount of which shall be determined by applying
to the quantities or dimensions shown on the approved plan the following
rates per unit:

A.
Prior to acceptance by the Village of the dedication of the street as guaranteed by § A134-4A(2) above, the developer shall deposit with the Village Clerk a maintenance bond of acceptable surety or shall deposit with the chief fiscal officer of the Village acceptable negotiable government bonds, cash or certified check or letter of credit drawn upon a national or state bank, payable at sight to the Village Board, guaranteeing that, for a period of one year from the date of acceptance of the dedication of the street by the Village, the developer will maintain the street to the standard of construction set by these specifications, normal wear and tear excepted. This shall be interpreted to mean that the developer will, at his own expense, repair and make good any defects or damage which may develop during this maintenance period as a result of faulty construction within the right-of-way or as a result of other construction by the developer off the right-of-way. During the maintenance period the Village shall be responsible for snow and ice control, street cleaning, cleaning of culverts and catch basins and other work of a similar routine nature, provided that such work has in no way been caused by the developer's operations.
B.
The amount of the maintenance bond shall be at least
equal to 10% of the original amount of the performance bond.
C.
Subsequent to the acceptance of the dedication of
the street and after receipt of the maintenance bond, the Village
Board shall release the performance bond, letter of credit or other
security.
A.
The proposed street will serve subdivisions with lots
one acre in size.
B.
The proposed street shall not be or be reasonably
expected to become a through, commercial or industrial street.
C.
The proposed street shall be a dead-end, loop or other
minor street within a development as distinguished from a principal
collector street.
The developer shall establish and clearly mark
on site the limits of the road right-of-way and easements, the center
line and grades of the road pavement and the location and elevation
of drainage and drainage structures in accordance with the approved
plans. Such markers shall be maintained at the developer's expense
until the construction of drainage, road pavement, curbs, sidewalks
and shoulders has been completed, inspected and approved by the Village
Engineer.
A.
The developer shall complete the shaping of the road
right-of-way, streams and ditches and easement areas to the line and
grade as shown on the approved plan and as otherwise may be directed
by the Village Engineer. All unsuitable or unstable materials shall
be completely excavated and removed from the right-of-way and all
rock or boulders larger than six inches in diameter shall be excavated
at least eight inches below the finished subgrade of 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 Superintendent
of Highways and shall be placed in layers not exceeding eight inches
in depth, each layer to be thoroughly compacted by rolling with a
three-wheel, sheepsfoot, pneumatic tired or padded 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 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 Board of Trustees has accepted dedication
of the right-of-way.
The storm drainage system shall be designed
in accordance with the criteria established by the County of Rockland
based on its 1959 county-wide drainage study. The minimum grade of
any drainage pipe shall be 1%.
A.
The widths of the trench in which the pipe is placed
shall be sufficient to permit thorough tamping of the backfill under
the haunches and around the pipe. Where rock, in either boulder or
ledge formation, is encountered, it shall be removed below grade and
replaced with suitable materials in such a manner as to provide an
earth cushion having a thickness under the pipe of not less than eight
inches; and where there are excessively heavy fills over the top of
the pipe, the Village Engineer may specify that an earth cushion up
to 1/2 inch in thickness per foot of fill be placed over the top of
the pipe. In no case shall the top of any drainage pipe be less than
18 inches below the finished grade of the pavement. Where soft, spongy
or other unstable soil is encountered at the grade established, all
such unstable soil under the pipe and for a width of one diameter
on each side of the pipe shall be removed and replaced with run-of-bank
gravel or other acceptable material. In all cases the bed shall be
thoroughly compacted and shall provide a firm foundation for the pipe.
B.
Pipe shall be laid to true line and grade on the prepared
bed of the trench. All connections for making field joints in corrugated
metal pipe shall consist of corrugated metal bands so constructed
as to lap on equal portions of each of the culvert sections to be
connected. All joints in making field connections of reinforced concrete
pipe shall be filled with portland cement mortar.
D.
Any additional drainage facilities not shown on the
approved plan and which may be ordered by the Village Engineer shall
be constructed by the developer at the developer's expense and in
accordance with these specifications.
A.
Storm drain and culvert pipe shall be reinforced concrete
with a minimum diameter of 15 inches.
B.
Reinforced concrete pipe shall conform to the standard
specifications for reinforced concrete culvert pipe adopted by the
American Society for Testing Materials and designated as C 76-59T
Class III.
C.
All reinforced concrete pipe shall be manufactured
with slip joints or bell and spigot joints.
D.
Each piece of reinforced concrete pipe shall be marked
with the specification number and the date of manufacture.
The specifications and drawings at the end of
this chapter show the minimum acceptable construction for typical
catch basins and curb inlets. Whenever, in the opinion of the Village
Engineer, ground conditions or other circumstances require it, larger
or heavier materials, additional materials, reinforcing or other modifications
and improvements in design and construction shall be made as directed
by the Village Engineer any time prior to paving.
A.
Location. Catch basins shall be constructed at all
points of change of slope or alignment and at all junction points.
At no time shall catch basins be spaced farther apart then 300 feet
on slopes less than 3%, 250 feet on slopes from 3% to 6% and 200 feet
on slopes over 6% in steepness.
B.
Excavation and concrete base. The hole for a catch
basin shall be excavated to a depth of 35 inches below the designated
elevation of the invert of the effluent pipe. Crushed stone or run-of-bank
gravel to a uniform depth of nine inches leveled and compacted over
the entire area under the base shall be laid in the hole. On this
stone or gravel shall be laid an eight-inch-thick slab of one-to-two-to-four-mix
portland cement concrete. The slab shall extend four inches beyond
the outside of the walls of the catch basin on every side. The slab
shall be smooth and level. Through the center of the slab there shall
be an opening for drainage one square foot in area, which shall be
protected and kept clean of concrete, mortar or other obstructing
materials during construction.
C.
Walls. Only precast catch basins shall be used.
D.
Curb inlets.
(1)
All catch basins shall be capped with curb inlets
having a minimum frame opening of thirty by forty-eight (30 x 48)
inches. Curb inlets shall be similar or equal to either Campbell Foundry
Company Pattern No. 2501 or Campbell Foundry Company Pattern No. 2541
(stream flow grating), as designated by the Superintendent.
(2)
Curb inlets shall be installed so that the top
of the grating is two inches below the finished grade, and the pavement
shall be sloped toward the inlet as shown on the drawings at the end
of this chapter.
(3)
Curb-front openings on all curb inlets shall
have, centered in the opening, a solid horizontal bar to prevent the
ingress of small children. This bar shall be part of the casting or
solidly welded in place subsequent to manufacture.
E.
Steps. Catch basins having a depth greater than 48
inches from the finished surface to the top of the concrete base shall
be provided with steps. Steps shall be of wrought iron having a minimum
diameter of 3/4 inch, which shall be hot-bent to shape and hot-dipped
galvanized after bending. They shall be solidly set in the masonry
at the time of construction and shall extend all the way through the
wall. The steps shall extend 4 1/2 inches inside the wall of
the catch basin. The top step shall be not more than 18 inches below
the finished surface, and thence to the base, steps shall be no more
than 18 inches apart.
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 Village 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 Village 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 to exceed 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 four-inch
square hole, not more than 70% by weight to pass the No. 40 mesh sieve
and not more than 10% by weight to pass the No. 200 mesh sieve.
B.
The materials shall be placed on the finished subgrade
by means of mechanical spreaders 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 Village 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.
After the foundation course has been completed as
the applicable sections of these specifications dictate and to the
satisfaction of the Village Engineer, the developer shall construct
an asphaltic cement base course four inches thick as called for in
these specifications. Since it is imperative that this course conform
accurately to the line, grade and cross section specified and as called
for on the plans, the developer shall set up pins and lines or other
controlled devices to attain the desired accuracy. Rolling shall begin
at the sides or curbline and continue towards the center and shall
continue until there is no movement of the course ahead of the roller.
B.
The developer shall install an asphaltic concrete
base course to a four-inch compacted thickness. After the foundation
course has been completed to the satisfaction of the Village Engineer,
asphaltic concrete conforming to the current specifications of the
NYSDPW of 1957 for item 45SX, bottom course asphaltic concrete Type
1A, shall be uniformly spread by a self-propelled mechanical spreader
equipped with tamping bars and heating unit and in sufficient depth
so as to provide a finished compacted thickness after rolling equal
to that specified above. The base material in place shall be thoroughly
rolled with a ten-ton roller.
C.
No trucking or construction traffic shall be permitted
on any base course until the wearing surface has been constructed.
A.
After the stone or asphaltic concrete base course
has been completed to the satisfaction of the Village Engineer, a
two-course bituminous concrete wearing course shall be constructed
conforming to the NYSDPW specifications of 1957 for item 51M, asphalt
concrete.
B.
After the base course has been thoroughly cured and
cleaned of all foreign material, a bituminous concrete binder course
shall be uniformly spread by a self-propelled mechanical spreader
with tamping bars and heating unit in sufficient depth so 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 gallon 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 so as to provide a finished compacted thickness after rolling
of not less than 1 1/2 inches. The fine wearing course in place
shall be thoroughly compacted with a two- or three-wheel 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.
B.
Three-inch porous tile shall be laid in coarse washed
sand under all curbs as shown on Figure 8. This underdrain shall be
so graded that any water under the curbs will drain to the nearest
catch basin where the underdrain shall be connected as shown on Figure
7.[2]
[2]
Editor's Note: Figures 8 and 7 are included
at the end of this chapter.
C.
Concrete shall be finished and cured to the satisfaction
of the Village Engineer. The developer shall, at his own expense,
replace any curbing damaged before dedication and any curb which proves
defective or is damaged by his operations during the two-year maintenance
period.
A.
The developer shall so design, lay out and construct
all driveways both within and without the limits of the right-of-way
that the latest models of modern cars may enter and leave the right-of-way
without difficulty.
The developer shall construct four-inch-thick
reinforced portland cement concrete sidewalks on both sides of streets
as shown on Figure 4.[1] Concrete shall be of a four-thousand-five-hundred-pound-per-square-inch
mix, air-entrained with Durex or equal, one course, properly screened
and finished to true grade with wooden float, and shall be cured,
all to the satisfaction of the Village Engineer.
[1]
Editor's Note: Figure 4 is included at the
end of this chapter.
The developer shall construct all street intersections
in accordance with Figure 12 except in the case of a new street intersecting
an existing narrow road, when such construction shall be modified
as shown on Figure 13.[1]
[1]
Editor's Note: Figures 12 and 13 are included
at the end of this chapter.
The developer shall furnish and install a four-way
street name sign at every street intersection made by the streets
he constructs. Signs and posts shall conform to the standards established
by the Village Board.
A.
Monuments shall be set on all right-of-way lines of
streets at all street intersections, angle points, points of curve
and subdivision corners. There shall be a clear foresight and backsight
to adjacent monuments on the right-of-way line or lines on which a
monument is set.
B.
Monuments shall be 36 inches long, five inches square
at the top tapering to six inches square at the bottom, and shall
have centered in the top a three-eighths-inch or one-half-inch drill
hole, three-eighths-inch or one-half-inch steel rod slightly protruding,
or some other permanent and satisfactory center mark. Monuments shall
be of cut granite free from imperfections or of concrete and similar
or equal to those supplied by Bergen Building Block, Inc., Ridgefield
Park, New Jersey.
C.
Monuments shall not be set before final grading has
been completed nor shall they be set while frost is in the ground.
They shall be so set that the top is flush with the finished grade.
They shall be so set and tamped as to prevent settlement or shifting.
D.
The developer's engineer and/or licensed land surveyor
shall certify that the location of all monuments is accurate before
acceptance of the street by the Village Board.
Where surface water must be lead through other
than right-of-way gutters and storm drains or existing stream channels,
drainage easements having a minimum width of 15 feet shall be provided
in the approved plans. A greater width than 15 feet shall be provided
where called for by other provisions of these specifications.
No open ditches will be permitted in lieu of
storm drain pipe.
Roof and cellar drains shall in no case be allowed
to flow onto the right-of-way. With the approval of the Village Engineer
in writing, these drains may be piped to the street stormwater pipe
drain, to which they shall be connected on top only. Such drains must
be installed prior to the start of fine grading of the streets.
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 tee or a circle as required
by the Village Planning Board and shall be constructed as shown on
Figures 17 and 18.[1] The temporary type of construction shall be used only
when authorized by the Planning Board because of the foreseeable future
extension of the street. The circular-shaped turnaround shall be completely
paved, with no center island.
[1]
Editor's Note: Figures 17 and 18 are included
at the end of this chapter.
A.
Streets shall be so designed that finished tangent
grades will not be less than 1% nor more than 10%.
B.
Every change in grade shall be effected with a vertical
curve of sufficient length to ensure adequate stopping sight distance
and to provide for smooth transition. These vertical curves shall
be designed in accordance with the graph shown on Figure 19 of these
specifications,[1] which is taken from New York State standards for thirty-mile-per-hour
speeds.
[1]
Editor's Note: Figure 19 is included at the
end of this chapter.
Final decision as to the interpretation of any
part of these street specifications shall rest with the Village Engineer.
He shall have the authority to modify the requirements of these specifications
when, in his opinion, conditions make it impracticable to follow the
strict letter of these specifications or when conditions make it unnecessary
to do so, such as for example:
A.
When a storm drain meets or follows an existing brook
so that a one-percent grade cannot be obtained without unreasonable
channel changes, the Village Engineer may allow a grade of less than
1%, provided that the pipe size is adequately increased.
B.
When the subbase of a street or road is already composed
of an acceptable granular material, the Village Engineer may waive
or modify the requirement of a foundation course.
C.
When the existing soil under the concrete curb is
already composed of a sufficiently porous material to ensure a proper
underdraining of the pavement, the Village Engineer may waive or modify
the requirements for curb underdrains.
