[Adopted 4-1-1991 (Ch.
127, Art. I, of the 1992 Code)]
It is the purpose of these specifications to establish minimum
acceptable standards of street construction for subdivisions in the
Village of Woodridge, including but not limited to width, design,
drainage, construction of base and pavement, curbs, sidewalks and
signs. Dedication of the right-of-way will not be accepted until the
developer's professional engineer or the Director of Public Works
shall have certified to the Village 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 and/or the Director of Public Works 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.
A 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 be submitted to
the Director of Public Works and/or the Village Engineer, and then
to the County Superintendent of Highways when any street drains towards
or may otherwise affect a county highway, and then shall be returned
to the Village Planning Board for review and approval under the applicable
subdivision regulations of the Village. 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 Director of Public Works if, during the progress
of the work, in the opinion of the Director of Public Works, the Village
Engineer and/or the County Superintendent of Highways, such additional
structures or facilities are necessary to assure the durability of
the pavement, the future maintenance of the right-of-way or the welfare
or safety of the public, except that the Village 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 Village 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 Village 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 a certified check
drawn upon a national or state bank payable at sight to the Village
Board guaranteeing that:
(1) Within two years the developer will complete all the construction
within the right-of-way, including roadways, 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) Upon certification by the developer's professional engineer
or by the Director of Public Works 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
the 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, negotiable government
bonds, cash or a 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 Village
Board of the Village of Woodridge.
C. The table of rates for computing the total amount of the performance
bond shall be as follows:
(1) For each linear foot of:
(a)
Major or through streets: $25.
(2) For each cubic yard of rock excavation: $20.
(3) For each linear foot of storm drain pipe:
(a)
Fifteen-inch round on 18 inches by 11 inches oblate: $4.50.
(b)
Eighteen-inch round or 22 inches by 13 inches oblate: $5.25.
(c)
Twenty-one-inch round or 15 inches by 16 inches oblate: $6.
(d)
Twenty-four-inch round or 29 inches by 18 inches oblate: $7.
(e)
Thirty-inch round or 36 inches by 22 inches oblate: $11.50.
(f)
Thirty-six-inch round or 43 inches by 27 inches oblate: $15.
(g)
Forty-two-inch round or 50 inches by 31 inches oblate: $20.
(h)
Pipe over 42 inches in diameter, concrete culverts and bridges:
as established by the Director of Public Works.
(4) For each catch basin:
(a)
Up to five feet in depth: $250.
(b)
For each additional foot to 10 feet: $35.
(c)
For each additional foot over 10 feet: $50.
(5) For each vertical foot of manhole: $180.
(6) For each concrete headwall: $150.
(7) For each street name sign: $25.
A. Prior to acceptance by the Village of the dedication of the street
as guaranteed by the rates 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 a certified check 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 that 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 other construction by the developer of the right-of-way. During
the maintenance period, the Village shall be responsible for snow
and ice control, street cleaning, the 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 or road,
the developer must submit a detailed survey map (as-built) showing
the location of the street or road within the easement. After receipt
of the above, along with deeds, the Village Board may release all
or part of the performance bond.
D. In the opinion of the Director of Public Works, the maintenance bond
will be extended for more than one year when the developer is continuing
development through the bonded area.
A. The Village 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:
[Amended 5-4-1992 by L.L.
No. 1-1992]
(3) Commercial or industrial street.
B. Final plans shall be drawn to show, and the developer shall construct,
each street in accordance with the particular specification for its
designated classification, as also hereinafter set forth, as well
as in accordance with the specifications common to all classifications.
A proposed street shall be designated a major or through street
when any of the following conditions exist:
A. The proposed street is in direct and logical continuation of a street
that carried 500 or more cars during a twelve-hour period, during
peak season months, as shown by the latest traffic count.
B. 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.
C. The proposed street is the principal collector for 300 or more homes
in the neighborhood.
D. The proposed street shall/could logically be expected to become a
major street because of future construction or other foreseeable circumstances.
A proposed street shall be designated a commercial or industrial
street when any of the following conditions exist:
A. The proposed street is in an area zoned for commerce or industry.
B. The proposed street is on or so close to the dividing line between
a residential and commercial or industrial area that it may reasonably
be expected to carry a substantial volume of commercial or industrial
traffic.
C. The proposed street creates a shorter and more convenient route between
a commercial or industrial area and a major traffic artery.
D. The proposed street for any other reason may be expected to carry
a substantial volume of commercial or industrial traffic.
A. A proposed street shall be designated a suburban-type street when
any of the following conditions exist:
(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 §
344-7C above.
B. This classification is intended to cover the majority of subdivision
streets.
A proposed street shall be designated a rural-type street when
any of the following conditions exist:
A. The proposed street shall serve residential subdivisions with lots of a minimum size of one acre where rezoning to smaller lot size is not designated in Chapter
400, Zoning, or contemplated in the Comprehensive Plan.
B. 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.
C. The proposed street does not or cannot be reasonably expected to
carry a substantial volume of traffic.
Figures 2, 3, 4 and 5 show cross sections of each of the four classifications
of subdivision streets. These give the required design, dimension
and construction details which are applicable to a particular classification.
Following is a comparative summary sheet which lists the major items
of construction for all types of streets and may be useful as a checklist
of requirements. Thereafter are set forth the general and more-detailed
specifications for design and construction applicable to all streets.
The developer shall design and construct streets which shall conform

at all times during the course of construction of the subdivision
and until such time as the Village Board has accepted dedication of
the right-of-way.
A. Design. The storm drainage system shall be designed in accordance
with the criteria established by the Village of Woodridge. The minimum
grade of any drainage pipe shall be 1%.
B. Excavation, laying and backfilling.
(1) 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 Director
of Public Works 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.
(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 bands shall be 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.
(3) Backfilling of trenches shall be done in accordance with the criteria established under the development of rights-of-way, §
344-13C, Excavating, filling and rough grading, of these specifications.
(4) Any additional drainage facilities not shown on the approved plan
and which may be ordered by the Director of Public Works shall be
constructed by the developer at the developer's expense and in
accordance with these specifications.
C. Pipe.
(1) Storm-drain and culvert pipe may be of either full-paved corrugated
metal or reinforced concrete with a minimum diameter of 15 inches.
(2) Round corrugated metal pipe shall conform to Item II and oblate corrugated

for reinforced concrete culvert pipe adopted by the American Society
for Testing and Materials and designated as C76-59T, Class III.
(4) All reinforced concrete pipe shall be manufactured with slip joints
or bell-and-spigot joints.
(5) Each piece of reinforced concrete pipe shall be marked with the specification
number and the date of manufacture.
The following specifications and drawings show the minimum acceptable
construction for typical catch basins and curb inlets. Whenever, in
the opinion of the Director of Public works, 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 Director
of Public works at 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 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.
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 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
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.
(1) To a maximum depth of five feet below the finished surface, the catch
basin walls shall be constructed of solid concrete catch basin corner
and stretcher blocks six inches thick.
(2) From five feet to a maximum depth of 10 feet below the finished surface,
the walls shall be constructed of solid concrete catch basin corner
and stretcher blocks eight inches thick.
(3) Below 10 feet from the finished surface, the catch basin walls shall
be 12 inches thick and shall be constructed of concrete block conforming
to ASTM Designation C-139. All hollows in or between blocks in each
course shall be completely filled with mortar before the succeeding
course is laid so that the finished wall is solid.
(4) All blocks forming the catch basin walls shall be laid up with mortar
composed of Portland cement and mortar sand conforming to New York
State Department of Public Works Specifications in the proportions
of 1:2.
(5) Inside dimensions of the catch basin shall remain constant from top
to bottom and shall match the frame opening of the curb inlet to be
used.
(6) Precast catch basins may be used if approved by the Director of Public
Works.
D. Installation of pipes.
(1) Concrete blocks around all pipes entering or leaving catch basins
shall be cut to fit the contours of the pipe as closely as possible.
Remaining holes 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 lower than the elevation of the top of the effluent pipe.
(3) When the diameter of the influent pipe is the same as or smaller
than that of an effluent pipe, the elevation of the invert of the
effluent pipe shall be equal to or lower than the invert of the influent
pipe. In no case shall the top of any influent pipe be more than five
feet above the invert of the effluent pipe.
E. 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 No. 2501 or Campbell
Foundry Company Pattern No. 2541 (stream-flow grating), as designated
by the Director of Public Works.
(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 on the pavings which follow.
(3) Curbfront 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.
F. Steps. Catch basins having a depth greater than 60 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 not 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 Director
of Public Works.
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 materials 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 Director of Public Works, the developer shall furnish and place
a foundation course of approved run-of-bank gravel, shale, 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 course to fine. Not more than
70% by weight shall pass the No. 40 mesh sieve, and not more than
10% by weight shall pass the No. 200 mesh sieve. Soil samples from
the stockpile of foundation course material should be certified by
a licensed engineer as meeting specifications, with copies of the
results sent to the Director of Public Works.
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 Director of Public Works 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 Director of Public Works, the developer shall construct a base
course of clean, dry, one-and-one-half-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 ten-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 toward 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 15 and October 31, and when the stone is dry and clean
and 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 the
latest New York State Department of Public Works Specifications for
Item 64P. Immediately after the application of the bituminous material
and while the liquid is still warm and in tacky condition, the surface
of the base course shall be filled with clean, dry five-eighths-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
stone cover is thoroughly keyed in the bitumen. Surplus stone shall
then be removed from the surface.
A. Between November 1 and May 14, with the prior written approval of
the Director of Public Works, one of the two following alternate base
courses may be substituted for the penetrated macadam base course
specified above.
(1) Stone- or sand-filled base course. Under this alternate, the developer
shall increase by 20% the compacted thickness of the one-and-one-half-inch
crushed stone base specified for penetration macadam base course.
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 screening or sand shall be added and broomed about
the surface until the voids in the stone base are filled to the satisfaction
of the Director of Public Works. Water shall be sprayed on the surface
if, in the opinion of the Director of Public Works, further consolidation
or filling of the base can be effectuated. Care shall be exercised
to ensure 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 aggregate is exposed.
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.
(2) Asphaltic concrete base course. Under this alternate, the developer
shall substitute an asphaltic concrete base course equal in compacted
thickness to that specified for penetration macadam base course. After
the foundation course has been completed to the satisfaction of the
Director of Public Works, asphaltic concrete conforming to the current
specifications of the New York State Department of Public Works 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 a heating unit and in sufficient depth so as
to provide a finished compacted thickness after rolling equal to that
specified for penetration macadam base course. The base material in
place shall be thoroughly rolled with a ten-ton roller.
B. 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 Director of Public Works, a two-course
bituminous concrete wearing course shall be constructed conforming
to the latest New York State Department of Public Works specifications
of 1985 for Section 400, Bituminous Pavements.
B. After the base course has not been thoroughly cured and cleaned of
all foreign material, a bituminous concrete binder course shall be
uniformly spread by a self-propelled mechanical spreader equipped
with tamping bars and a 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 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 a heating unit and in sufficient
depth so 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 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.
A. Six-inch Portland cement concrete curbs shall be constructed on both
sides of the street as shown on Figure 2, 3, 4 or 5 and to the dimensions
and specifications shown on Figure 8.
B. Three-inch porous tile shall be laid in coarse, washed sand under
all curbs as shown on Figure 8. This underdrain pipe, meeting New York State Department
of Transportation Item No. 605-2.01, 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.
C. Concrete shall be finished and cured to the satisfaction of the Director
of Public Works. 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 one-year maintenance period.
A. The developer shall construct all driveway entrances according to
the dimensions and specifications shown on:
(1) Figure 9, Commercial and Industrial Type Streets.
(2) Figure 10, Plan of Driveway Entrance on Through and Suburban Streets.
(3) Figure 11, Driveway Entrance on a Rural Street.
B. All entrance construction shall be finished and cured to the satisfaction
of the Director of Public Works.
C. All necessary driveway entrances within the subdivision shall be
constructed at the time of construction of the curbs.
In a district where sidewalks are intended, the 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-entranced 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 Director of Public Works.
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 it shall be modified as shown on Figure
13.
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.
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 width greater than 15 feet shall be provided where called
for by other provisions of these specifications.
A. With the approval of the Director of Public Works and/or the Village
Engineer, open ditches may be used in lieu of storm drain pipes 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 stone is carried by the soil
and not by the stone adjacent. All stone shall weigh between 50 and
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 riprapped for a distance of at least 30 feet beyond
the end of the pipe.
Roof and cellar ditches shall in no case be allowed to flow
onto the street right-of-way. With the approval of the Director of
Public Works and 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. The temporary type of construction shall be used only
when authorized by the Village Planning Board because of the foreseeable
future extension of the street. The circular shaped turnaround shall
be completely paved with no center island.
Streets shall be so designed that finished tangent grades will
not be less than 1% nor more than 10%. 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, which is taken from New York
State standards for speeds of 30 miles per hour.
The final decision as to the interpretation of any part of these
street specifications shall rest with the Director of Public Works.
He shall have the authority to modify the requirements of these specifications
when, in his opinion, conditions make it impractical 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
Director of Public Works 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 Director of Public Works 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 Director of Public Works may waive or modify
the requirements for curb underdrains.
