[HISTORY: Adopted Orangetown Town Board 4-25-1960. Amendments
noted where applicable.]
It is the purpose of these specifications to establish minimum
acceptable standards of street construction for subdivisions in the
Town of Orangetown 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 or qualified licensed land
surveyor and the Town Superintendent of Highways shall have certified
to the Town Board in writing that the construction of the street or
streets has been completed in accordance with the approved plans and
the specifications which follow.
In his written certification, as required above, the developer's
professional engineer or qualified licensed land surveyor 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.
Plans of the proposed street shall be prepared by a qualified
engineer or qualified land surveyor 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.
Plan shall first be submitted to the Town Superintendent of Highways
and Town Engineer; and then to the County Superintendent of Highways,
when any street drains toward or may otherwise affect a county highway;
and then to the Town Planning Board for review and approval under
the applicable subdivision regulations of the Town. 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 Town
Superintendent of Highways if, during the progress of the work, in
the opinion of the Town Superintendent of Highways, the Town Engineer
and/or the County Superintendent of Highways such additional structures
or facilities are necessary to assure the durability of pavement,
the future maintenance of right-of-way, or the welfare or safety of
the public. If construction has not been started within one year from
the date of final approval by the Town Planning Board, plans shall
be resubmitted and approved as above.
A.
Performance Bond. Prior to the start of construction of
any improved street, the developer shall deposit with the Town Clerk
a Performance Bond of acceptable surety or shall deposit with the
Chief Fiscal Officer of the Town acceptable negotiable government
bonds, cash or certified check drawn upon a national or state bank
payable at sight to the Town 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 or licensed land surveyor and by the Town Superintendent
of Highways 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 Town for use as a public
highway free and clear of all liens and encumbrances. This guarantee
of dedication shall apply to the owner of the property as well as
the developer, where the two are not synonymous.
|
As guarantee for the performance of the above requirements,
the developer shall deposit, as heretofore set forth, a surety bond,
negotiable government bonds, 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 rates per unit as established
by the schedule of rates attached hereto and forming a part hereof
(Figure 1).

B.
Maintenance Bond. Prior to acceptance by the Town of the
dedication of the street as guaranteed by Paragraph (2) under Performance
Bond, above, the developer shall deposit with the Town Clerk a Maintenance
Bond of acceptable surety or shall deposit with the Chief Fiscal Officer
of the Town acceptable negotiable government bonds, cash or certified
check drawn upon a national or state bank payable at sight to the
Town Board, guaranteeing that, for a period of two years from the
date of acceptance of the dedication of the street by the Town, 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 Town 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 such work has in no way been caused by the developer's
operations.
|
The amount of the maintenance bond shall be at least equal to
20% of the performance bond.
|
A.
Also prior to acceptance by the Town of the dedication
of the street, the developer shall file with the Town Clerk evidence
that he has taken out for the same period of time as the Maintenance
Bond an insurance policy in the amounts of $100,000/$300,000 for public
liability, and $50,000 for property damage naming as the insured the
Town Board and/or the Town Highway Department and/or the Town Superintendent
of Highways.
B.
The purpose of this requirement for insurance is to protect
and defend the Town against any claims which may arise because of
the operations of the developer or of possible defects in work performed
by him.
C.
Subsequent to the acceptance of the dedication of the street
and after receipt of the Maintenance Bond and evidence of insurance
by the Town, the Town Board shall release the Performance Bond.
The Town Planning Board shall determine and designate into which
of the four following classifications each proposed subdivision street
falls on the basis of one or more of the criteria hereinafter set
forth:
A.
Major or through streets.
B.
Commercial or industrial streets.
C.
Suburban-type streets.
D.
Rural-type streets.
|
Final plans shall be drawn to show, and the developer shall
construct each street in accordance with, the particular specifications
for its designated classification as also hereinafter set forth as
well as in accordance with the specifications common to all classifications.
|
A.
Major or through streets.
(1)
The proposed street is the direct and logical continuation
of a street that carried 500 or more cars during a twelve-hour period
as shown on the latest traffic count.
(2)
The proposed street creates a shorter and more convenient
through-traffic artery so that it can be reasonably expected that
traffic will be diverted from other major streets to such an extent
that it will reach at least 500 cars in 12 hours, two years after
opening.
(3)
The proposed street is the principal collector for
300 or more homes in the neighborhood.
(4)
The proposed street could logically be expected to
become a major street because of future construction or other foreseeable
circumstances.
B.
Commercial and industrial streets.
(1)
The proposed street is in an area zoned for commerce
or industry.
(2)
The proposed street is on or so close to the dividing
line between a residential and a commercial or industrial area that
it may reasonably be expected to carry a substantial volume of commercial
or industrial traffic.
(3)
The proposed street creates a shorter and more convenient
route between a commercial or industrial area and a major traffic
artery.
(4)
The proposed street for any other reason may be expected
to carry a substantial volume of commercial or industrial traffic.
C.
Suburban-type streets.[1]
(1)
The proposed street will serve subdivisions with
lots under one acre in size.
(2)
The proposed street shall not be or be reasonably
expected to become a through, commercial or industrial street.
(3)
The proposed street shall be a dead end, loop or
other minor street within a development as distinguished from a principal
collector as described in Paragraph (3) of Criteria for Major or Through
Streets.
[1]
Note: This classification is intended to cover the majority
of subdivision streets.
D.
Rural-type streets.
(1)
The proposed street shall serve residential subdivisions
with lots of a minimum size of one acre, where rezoning to small lot
size is not designated in the zoning ordinance or contemplated in
the Comprehensive Plan.
(2)
The proposed street is not or cannot reasonably be
expected to become a continuation or extension of a street of one
of the three above-described classifications. Should such be the case,
the proposed street shall take the classification of the street of
which it is a continuation or extension.
(3)
The proposed street does not or cannot reasonably
be expected to carry a substantial volume of traffic.
A.
The pages immediately following (Figures 2, 3, 4 and 5)
show cross sections of each of the four classifications of subdivision
streets. These give the required design, dimensions and construction
details which are applicable to a particular classification.
B.
Figure 6 is a comparative summary sheet which lists the
major items of construction for all types of streets and may be useful
as a check list of requirements. Thereafter are set forth the general
and more detailed specifications for design and construction applicable
to all streets.
C.
The developer shall design and construct streets which
shall conform to both the specific and the general specifications.
A.
Layout. The developer shall establish and clearly mark
on site the limits of 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, side-walks
and shoulders has been completed, inspected and approved by the Town
Superintendent of Highways and Town Engineer.
B.
Excavation, filling and rough grading.
(1)
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 Town Superintendent of Highways. 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.
(2)
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 Superintendent
of Highways and shall be placed in layers not exceeding eight inches
in depth, each layer to be thoroughly compacted by rolling with three
wheel, sheeps-foot, pneumatic-tired 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.
(3)
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.
(4)

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.
Design. The storm drainage system will 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%.
B.
Excavation, laying and backfilling.
(1)
The width 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 Town Superintendent of Highways 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.
(2)
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 motar.
(3)
Backfilling of trenches shall be done in accordance
with the paragraph or fills under the above heading of Excavation,
Filling and Rough Grading.
(4)
Any additional drainage facilities not shown on the
approved plan and which may be ordered by the Town Superintendent
of Highways shall be constructed by the developer at the developer's
expense and in accordance with these specifications.
C.

(5)
Each piece of reinforced concrete pipe shall be marked
with the specification number and the date of manufacture.
D.
Catch basins and curb inlets. The following specifications
and drawings show the minimum acceptable construction for typical
catch basins and curb inlets. Whenever, in the opinion of the Town
Superintendent, 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 Town Superintendent at any time prior to
paving.
E.
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 than 300 feet on slopes
less than 3%; 250 feet on slopes from 3% to 6%; and 200 feet on slopes
over 6% in steepness.
F.
Excavation and concrete base. Hole for 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 1-2-4-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

(1)
Concrete blocks around all pipes entering or leaving
catch basin shall be cut to fit the contours of the pipes as closely
as possible. Remaining interestices shall be solidly filled with mortar
for the full thickness of the wall. Ends of all pipes shall be cut
off flush with the inside surfaces of the catch basin walls.
(2)
When the diameter of the effluent pipe is greater
than that of an influent pipe, the elevation of the top of the influent
pipe shall be no longer than the elevation of the top of the effluent
pipe.
(3)
When the diameter of the effluent pipe is the same
as or smaller than that of an influent pipe, the elevation of the
invert of the influent pipe shall be no lower than the elevation of
the invert of the effluent pipe. In no case shall the top of any influent
pipe be more than five feet above the invert of the effluent pipe.
I.
Curb inlets.
(1)
All catch basins shall be capped with curb inlets
having a minimum frame opening of 30 inches by 48 inches. Curb inlets
shall be similar or equal to either Campbell Foundry Company Pattern
#2501 or Campbell Foundry Company Pattern #2541 (Stream Flow Grating),
as designated by the Town 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 which follow.
(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.
J.
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 Town Superintendent of Highways.
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.
After the fine grade and all curbs have been constructed to
the satisfaction of the Town Superintendent of Highways, 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 four inch square hole, not more than 70% by weight pass the
#40-mesh sieve, and not more than 10% by weight pass the # 200-mesh
sieve.
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 Town Superintendent of Highways 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 Town Superintendent of Highways, the developer shall construct
a base course of clean, dry, 1 1/2 inch crushed stone. The stone
shall be evenly spread by means of an approved mechanical spreader
in such quantities that after being compacted with a 10 ton roller,
the thickness of the course shall be 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.
After the stone base course has been completed and only
between the dates of May 15th and October 31st, and when the stone
is dry and clean, free of frost, and the atmospheric temperature is
above 50° F., bituminous material shall be applied to the base
course by means of a pressure distributor at a rate of not less than
1/2 gallon of bituminous material per square yard per inch of compacted
thickness of stone, but in no event less than two gallons per square
yard. Bituminous material shall be 100 to 120 penetration paving asphalt
heated to a temperature of 275° F. to 350° F. and shall conform
to N.Y.S.D.P.W. specifications of 1957 for Item 64P. Immediately after
the application of the bitumonius material and while the liquid is
still warm and in tacky condition, the surface of the base course
shall be filled with clean, dry 5/8 inch stone, after which it shall
be thoroughly rolled with a self-propelled ten-ton roller. Additional
stone shall be applied and broomed about the surface during rolling
until all voids in the surface of the stone base course are completely
filled. Rolling shall continue until the cover stone is thoroughly
keyed in the bitumen. Surplus stone shall then be removed from the
surface.
Between November 1st and May 14th, with the prior written approval
of the Town Superintendent of Highways, one of the two following alternate
base courses may be substituted for the penetrated macadem base course
specified above:
A.
Stone- or sand-filled base course.
(1)
Under this alternate the developer shall increase
by 20% the compacted thickness of the 1 1/2 inch crushed stone
base specified for penetrated macadam base course.
(2)
After the stone base course is thoroughly compacted,
stone screenings or washed concrete sand shall be uniformly spread
upon the surface in sufficient quantities to fill the voids in the
stone-base course and shall be swept into the voids by means of a
gang drag-broom or by hand and then the base thoroughly rolled with
a ten-ton roller. Additional stone screenings or sand shall be added
and broomed about the surface until the voids in the stone base are
filled to the satisfaction of the Town Superintendent of Highways.
Water shall be sprayed on the surface if, in the opinion of the Town
Superintendent of Highways, further consolidation or filling of the
base can be effectuated. Care shall be exercised to insure that the
voids in the stone base are completely filled, but the quantities
of stone screenings or sand used and the operation of filling and
rolling shall not be such as to cause floating of the coarse aggregate.
All surplus filler shall be removed from the base course surface until
the top surface of the coarse aggregates are exposed.
(3)
If for any reason the subgrade or foundation course
materials shall become churned up into or mixed with the stone base
course, the developer shall remove such mixture and replace it with
clean crushed stone thoroughly compacted and properly filled, as above.
B.
Asphaltic concrete base course.
(1)
Under this alternate, the developer shall substitute
an asphaltic concrete base course equal in compacted thickness to
that specified for penetrated macadam base course.
(2)
After the foundation course has been completed to
the satisfaction of the Town Superintendent of Highways, asphaltic
concrete conforming to the current specifications of the N.Y.S.D.P.W.
of 1957 for Item 45SX, Bottom Course Asphaltic Concrete, Type 1A,
shall be uniformly spread by self-propelled mechanical spreader equipped
with tamping bars and heating unit and in sufficient depth as to provide
a finished compacted thickness after rolling equal to that specified
for penetrated macadam base course. The base material in place shall
be thoroughly rolled with a ten-ton roller.
(3)
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 Town Superintendent of Highways,
a two course bituminous concrete wearing course shall be constructed
conforming to the N.Y.S.D.P.W. 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 as to provide a finished
compacted thickness after rolling of not less than one and 1 1/2
inch. 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 gallon 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 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 wheel tandem roller weighing
approximately 10 tons.
D.
Extreme care shall be exercised in the placing of bituminous
concrete to insure 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.
A.
Six inch portland cement concrete curbs shall be constructed
on both sides of the street as shown on Figures 2, 3, 4 or 5 and to
the dimensions and specifications shown on Figure 8.

B.
That the approved six inches of material to be laid as
a foundation course for the concrete curb as shown in Figures 2, 3,
4, 5, and 6 be washed gravel, crushed stone or hard steam cinders
approved by the Town Engineer or Superintendent of Highways.
[Added 6-11-1962]
C.
Porous tile shall be laid in coarse washed sand under curbs
as shown on Figure 8 only where deemed necessary by the Town Engineer
or Superintendent of Highways.[1] This underdrain shall be so grated that any water under
the curbs will drain to the nearest catch basin where the underdrain
shall be connected as shown on Figure 7.
[1]
Editor's Note: Amended 6-11-1962.
D.
Concrete shall be finished and cured to the satisfaction
of the Town Superintendent of Highways. Developer shall at his own
expense replace any curbing damaged before dedication and any curb
which proved defective or is damaged by his operations during the
two year maintenance period.
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.
A.
Developer shall construct four-inch-thick reinforced portland
cement concrete sidewalks on both sides of streets as shown on Figures
2, 3 and 4. Concrete shall be of a 1-2-3 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
Town Superintendent of Highways.
B.
The #6 gauge, six-inch steel reinforcing mesh as shown
in the Sidewalk Details in Figures 2, 3 and 4 may be required in some
areas where deemed necessary by the Town Engineer or Superintendent
of Highways.
[Amended 6-11-1962]
C.
The approved porous material to be held as a foundation
course of the concrete sidewalk as shown in Sidewalk Details in Figures
2, 3 and 4 shall be washed gravel, crushed stone or hard steam cinders
approved by the Town Engineer or Superintendent of Highways.
[Added 6-11-1962]
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 it shall be modified as shown on Figure
13.
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 Town 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 3/8 inch or 1/2 inch drill hole, a 3/8 inch
or 1/2 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 set so that the top is flush with the finished grade. They
shall be so set and tamped as to prevent settlement or shifting.
D.
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 Town Board.
Where surface water must be led 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.
A.
With the approval of the Town Superintendent of Highways
and Town Engineer, open ditches may be used in lieu of storm drainpipes
when the grade of the land traversed is flat or when it is desirable
to drain and dry up the surrounding area.
B.
Open ditches shall be constructed in accordance with Figure
14 of these specifications, but in no case shall the grade of an open
ditch exceed 3%. Riprap, when called for, shall consist of field stone
or rough, unhewn quarry stones as nearly cubical in form as is practicable,
placed upon a slope not steeper than 1:2 and so laid that the weight
of the large stones is carried by the soil and not by the stone adjacent.
All stones shall weigh between 50 - 150 pounds each and at least 60%
of them shall weigh more than 100 pounds each.
C.
The largest stones shall be placed first, roughly arranged
and in close contact. The spaces between the larger stones shall be
filled with spalls of suitable size.
D.
Whenever a drainpipe enters an open ditch, the bottom and
sides of the ditch shall be rip-rapped for a distance of at least
30 feet beyond the end of the pipe.
|
|
Roof and cellar drains shall in no case be allowed to flow onto
the street right-of-way. With the approval of the Town Superintendent
of Highways and Town 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 turn-around shall be constructed. This turn-around shall
take the form of a tee or a circle as required by the Town Planning
Board and shall be constructed as shown on Figures 17 and 18. The
temporary type of construction shall be used only when authorized
by the Town Planning Board because of the foreseeable future extension
of the street. The circular-shaped turn-around shall be completely
paved with no center island.
A.
Streets shall be so designed that finished tangent grades
will not be less than 0.7% or more than 10%.
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. These vertical curves shall
be designed in accordance with the graph shown on Figure 19 of these
specifications which is taken from New York State standards for 30
M.P.H. speeds.
Final decision as to the interpretation of any part of these
street specifications shall rest with the Town Superintendent of Highways.
In the event that any part or parts of these Street Specifications
for Subdivisions, or of any ordinance or regulations which may govern
or otherwise affect them, is for any reason modified or invalidated,
the other portions of said specifications not affected thereby shall
remain in full force and effect.
