This article shall be known and may be cited
as the "Town of Stanford Street and Road Specifications Law."
It is the purpose of these specifications to
establish minimum acceptable standards for public/private street construction
in the Town of Stanford, Dutchess County, New York. In setting forth
these standards for the protection of the public safety, the Town
Board asserts that the specifications, standards and requirements
contained herein are the minimum standards to which all new streets
in the Town of Stanford must hereinafter be constructed whether or
not such streets shall be dedicated to the Town. Where such streets
are to be dedicated, such dedication shall not be accepted until the
applicant's professional engineer and the Town Superintendent of Highways
shall have certified to the Town Board in writing that the construction
of the street has been completed in accordance with the approved plans
and specifications that follow, and that the total right-of-way area
has been cleared of all debris and all construction completed in a
workmanlike manner.
In his or her written certification, as required
above, the applicant's professional engineer shall state clearly that
he or she, or his or her authorized representative, has inspected
all phases of the street construction and that all work has been completed
in accordance with the approved plans and specifications.
A.
Preparation; contents. A plan of the proposed street
shall be prepared by a qualified professional engineer and qualified
land surveyor licensed by the State of New York. The street improvement
plan may be prepared as a requirement of the subdivision and/or site
plan land development application as reviewed and determined by the
Planning Board or may be prepared for the improvement or extension
of existing roadways within the Town. Street improvement plans shall
show the following elements:
(1)
Proposed right-of-way described by courses and distances.
(2)
Location, width, profiles and grades of the proposed
roadway.
(3)
Cross sections of the roadway, and super elevations
if applicable and maximum safe design speed of curves.
(4)
Storm drainage system, including calculated runoffs,
culverts, ditches and other drainage structures with invert elevations,
slopes and calculated capacities.

street or streets, the elevation along the center line of the existing
street within 200 feet in each direction of the intersection.
(b)
Where steep cross slopes equal to or exceeding
25% exist along the proposed roadway alignment, elevations of all
proposed streets shall be shown every 100 feet at five points on a
line at right angles to the center line of the street. Said elevation
points shall be shown at the center line of the street, each property
line, and points 30 feet beyond the proposed right-of-way line.
(c)
Plans and profiles showing the location and
typical section of street pavements, including curbs and gutters,
sidewalks, manholes and catch basins, the location of street trees,
street lighting standards and street signs; the location, size and
invert elevations of existing and proposed sanitary sewers, stormwater
drains and fire hydrants; the location and design of proposed bridges
or culverts; and the location of all underground utilities.
B.
Submittals; review process.
(1)
Copies of plans. The applicant shall submit a minimum
of nine copies of roadway plans to the Planning Board for a roadway
proposed as a part of the subdivision and/or site plan land development
application review process. If the roadway improvement plans are prepared
for the improvement or extension of an existing roadway within the
Town, at least six copies of each of the plans shall be submitted
to the Town Board as follows: two copies to the Town Superintendent
of Highways, one copy for the Town Engineer or consulting engineer,
one copy to the Town Board, two copies to the Planning Board, and
one copy to any outside review agency. Additional copies may be required
by the Town Planning Board.
(2)
Preliminary layout approval. The Town Planning Board
shall review the plans for a roadway proposed as a part of the subdivision
and/or site plan land development application review and consider
all elements of the design prior to granting preliminary subdivision
and/or site plan approval. The Planning Board shall refer the preliminary
roadway layout plans to the Town Superintendent of Highways for review
and comment at least 10 days prior to the Planning Board's consideration
of preliminary subdivision and/or site plan approval. If the roadway
improvement plans are prepared for the improvement or extension of
an existing roadway within the Town which is not a part of a land
development review process by the Planning Board, whether being proposed
by a private or public entity (including the Town), the Town Superintendent
of Highways shall review the plans for the proposed street and make
an initial site inspection. The Town Superintendent of Highways shall
make a report to the Town Board concerning the proposed road. Based
upon this report and an initial review by the Planning Board, the
Town Board may grant preliminary layout approval or may require changes
to the proposed layout.
(3)
Technical review of plans. The Town Superintendent
of Highways, Town Board or Town Planning Board may request a technical
review of the proposed street plans by the Town Engineer or by a consulting
engineer employed by the Town for this purpose. The applicant shall
reimburse the Town for the actual costs of said review, including
but not limited to the professional fees charged by said engineer.
(4)
Inspection costs. In addition to technical review
of the plans, the Planning Board and/or the Town Board may require
field inspection of the proposed street during construction by the
Town Engineer or by a consulting engineer employed by the Town for
this purpose. The applicant shall reimburse the Town for the actual
costs of said review, including but not limited to the professional
fees charged by said inspector.
(5)
Offer of deed.
(a)
Following preliminary subdivision and/or site
plan approval and prior to final subdivision and/or site plan approval,
the applicant shall submit a legal description of the proposed street,
a title report indicating unencumbered ownership of the land by the
applicant, and if the proposed street is to be dedicated to the Town
the applicant shall submit an offer of cession and warranty deed to
the land within the proposed right-of-way and whatever other legal
instruments that might be considered necessary for review and approval
by the Town's attorney. All filing fees for any recording of the deed
or other required legal instrument in the Dutchess County Clerk's
office shall be paid by the applicant.
(b)
Following preliminary layout approval of roadway
improvement plans that are prepared for the improvement or extension
of an existing roadway within the Town by a private landowner that
does not require an approval from the Planning Board, a legal description
of the proposed street must be submitted to the Town Board for review.
Such proposed street must be owned in fee by the applicant and must
not be subject to any right or easement to others which would in any
way interfere with its use as a street at all times. If such street
is to be dedicated to the Town, it must be granted to the Town by
a full covenant and warranty deed containing the correct description
as shown on the approved map, which deed must be presented to the
Town in such form as may be required to be recorded in the Dutchess
County Clerk's office. All filing fees for the eventual recording
of the deed shall be paid by the applicant.
C.
Easements. Permanent and temporary easements must
be furnished in said deed granting to the Town the right, but not
necessarily the obligation, to maintain all outlets for surface water
or natural stream drainage which will run from such roadway over private
property to a point where a natural watercourse exists and to which
such outlet and easement will carry such water. A minimum of 30 feet
width of easement shall be required for the maintenance of said easement.
D.
Street improvement plans and subdivision plats. The
proposed roadway must be constructed to conform to the minimum requirements
and standards set forth herein, and notation citing the specifications
of streets in the Town of Stanford shall be affixed to the street
improvement plan and approved subdivision plat.
E.
As-built drawings required.
(1)
The required improvements shall not be considered
to be completed until the installation of the improvements has been
approved by the Town Superintendent of Highways and Town Engineer,
and approved by the Planning Board when roadway improvements are constructed
prior to final subdivision and/or site plan approval.
(2)
In addition, a map certified by a licensed professional
engineer or licensed land surveyor and satisfactory to the Town Superintendent
of Highways and Town Engineer must be submitted indicating the actual
location of the required improvements outlined above, the grades of
streets, the elevation of drainage structures, the location of underground
utilities and the location of required boundary monuments.
Plans submitted shall not be altered or amended
after having been approved by the Planning Board, the Town Superintendent
of Highways and the Town Board unless amended plans are resubmitted
and approved. However, the applicant, at his or her own expense, shall
provide additional storm drainage facilities or utilities as may be
ordered by the Town Superintendent of Highways if, during the course
of construction, 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 prevent any need
for future installations of utilities or culverts within the pavement
area, to assure the durability of pavement, future maintenance of
the right-of-way, or welfare and safety of the public. If construction
of said street 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.
Prior to the construction of any street, the applicant
shall file with the Town Board a highway construction agreement on
a form provided by the Town which sets forth the applicant's obligation
with respect to these specifications and other applicable laws, including:
(1)
That within two years the applicant will complete
all the construction within the right-of-way, including roadway, shoulders,
curbs, if any, gutters, storm drainage, etc.; and all utilities, including
hydrants and house connections for each lot in accordance with the
approved plans and these specifications; all stormwater drainage associated
with the public highway but outside of the right-of-way; and that
all claims for labor and materials in connection with said construction
have been paid in full prior to offering said street for dedication
to the Town.
(2)
That, upon certification by the applicant's professional
engineer and licensed land surveyor and by the Town Superintendent
of Highways and Town Engineer that the construction of the street
has been completed in accordance with the approved plans and specifications,
the applicant 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 applicant, where the two are not synonymous.
B.
Before the Planning Board Chairman or other authorized
person may sign a subdivision plat which includes a proposed street
or utilizes an existing street for lot frontage, the improvements
must either be completed or the applicant shall post with the Town
a surety to guarantee completion of required improvements. The surety
shall be in the form of a performance bond, cash, bank passbook, collateralized
letter of credit from a local banking institution that is acceptable
to the Planning Board, negotiable government bonds or certified check
drawn upon a national or state bank, payable at sight to the Town
of Stanford, subject to approval by the Town Board after review by
the Town Attorney.
(1)
The amount of said surety shall be determined by the
Town Superintendent of Highways and Town Engineer after review of
plans and estimates prepared by the applicant. The amount must be
sufficient to enable the Town or its authorized contractor to construct
the required improvements in the event that the applicant shall default.
The amount shall not be less than the estimated costs that are deemed
acceptable by the Town Superintendent of Highways and the Town Engineer.
(2)
The amount of said surety shall provide for the future
costs of material and labor and the costs which may be incurred by
the Town in collecting the surety. If the applicant has not accomplished
a substantial portion of the planned construction prior to posting
said surety, or if the form of surety is other than cash or certified
check, the amount of the surety shall be no less than 110% of the
current estimated costs of required improvements.
C.
Maintenance bonds.
(1)
Prior to acceptance by the Town of the dedication
of the street, the applicant shall deposit with the Town Clerk a maintenance
bond or 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 one year from the date
of acceptance of the dedication of the street by the Town, the applicant
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 applicant will, at his or her 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 applicant outside 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.
(2)
The amount of said maintenance bond shall be determined
by the Town Superintendent of Highways and Town Engineer and shall
be at least equal to 15% of the original amount of the performance
bond or, in cases where the original surety was calculated based on
partial improvements, the estimated cost of improvements for the entire
project, whichever is greater.
A.
The Town Planning Board shall determine the design classification of a street or portion of a street in accordance with Chapter 140, Subdivision of Land. Final plans shall be drawn to scale, and the applicant shall construct each street in accordance with the particular design specifications for the classification as set forth in the subdivision regulations, and for construction specifications as hereinafter provided.
B.
The five construction specifications for proposed
streets shall be as follows:
(1)
Suburban or commercial streets (40 feet of pavement,
five-foot shoulder, parking on both sides of the street, with curbs
and sidewalks). Should the Planning Board determine that on-street
parking on both sides of the street is not necessary for the specific
new street, then the pavement width may be reduced by nine feet for
each on-street parking lane that may be determined not to be required
(i.e., a suburban or commercial street with parking on one side shall
require a minimum pavement width of 31 feet, and pavement width with
no on-street parking shall require a minimum pavement width of 22
feet).
(2)
Rural collector roads (22 feet of pavement, three-foot
gravel shoulder).
(3)
Rural-type residential (low volume) roads (18 feet
of pavement, two-foot turf shoulder).
(4)
Private rural-type residential (low volume) roads
(18 feet optional gravel surface, two-foot turf shoulder).
(5)
Existing public streets.
B.
Rural collector roads: publicly owned roads that act
as collector roadways that serve rural agricultural and low-density
residential land uses; existing and proposed roads that connect to
existing Town, county or state roads and may provide access to more
than 25 single-family lots, either through direct access or through
existing or proposed connections to rural-type residential or rural-type
private roads.
C.
Rural-type residential (low volume) roads: publicly
owned roads that serve rural agricultural and low-density residential
land uses that connect to Town, county and state highways, and may
provide access for other rural-type residential and/or private roads.
Rural-type residential low-volume roads may provide direct access
to no more than 25 single-family lots, inclusive of lots that might
be reasonably anticipated to be created in future developments within
the immediate vicinity of the proposed road.
D.
Private rural-type residential (low volume) roads:
privately owned and privately maintained roads that serve rural agricultural
and low-density residential land uses. Private roads must directly
access Town, county or state roadways and are limited to serving as
the access means for a maximum of eight residences. Access to a private
road by means of a common drive is not permitted. Shared driveway
access to a private road is permitted.
E.
Existing public streets: any existing street which
was originally constructed to service low-density or agricultural
uses.
Figures 1 through 4 show the cross sections
of each of the construction classifications for new streets.[1] These figures give the required construction details which
are applicable to each classification. The general and more detailed
specifications shall be followed for design and construction which
are applicable to these classifications of streets. The applicant
shall design and construct streets which shall conform to both the
general and specific specifications.
[1]
Editor's Note: Figures 1 through 4 are included
at the end of this chapter.
A.
Prior to issuance of building permit. Prior to the
issuance of a building permit for any lot, the applicant shall complete
the clearing and grubbing and excavation, filling, rough grading,
and storm drainage, both within the development and the required off-site
drainage, as hereinafter specified. All street rights-of-way fronting,
and drainage easements serving, such lot and extending from existing
improved rights-of-way and easements up to and including the last
lots upon which a building permit is requested to be issued shall
be improved in order to assure suitable access by fire, police, ambulance
and other emergency vehicles to sites of actual building construction.
A cash bond or other surety will be required.
B.
Prior to issuance of certificate of occupancy. Prior
to the issuance of a certificate of occupancy for a structure on any
lot not fronting on any improved public street, the applicant shall
complete storm drainage, curbs, sidewalks and sanitary sewerage construction
within the right-of-way and any easements affecting the lot and all
right-of-way between that lot and existing improved public streets.
The applicant shall have installed all utilities, including house
connections and street lighting, in such right-of-way and shall fine
grade, construct all base course, and asphaltic concrete binder course
to the full design widths of street pavement. A cash bond or other
surety will be required.
C.

and Town Engineer find that any of the required improvements has not
been constructed in accordance with the approved plans and specifications,
the applicant shall be ordered to correct said deficiencies prior
to any further work.
A.
The applicant shall furnish and install street name
signs at all intersections in locations approved and directed by the
Town Superintendent of Highways and by the Planning Board when street
or roadway improvements are considered as a part of a subdivision
and/or site plan land development application review. Stop signs,
parking restrictions and warning signs shall also be installed by
the applicant at the direction of the Town Superintendent of Highways.
Signs shall be procured from authorized suppliers on the Town Superintendent
of Highway's suppliers list.
B.
All signs shall conform to the Manual on Uniform Traffic
Control Devices for Streets and Highways and shall be set in concrete
to a depth of at least three feet below the ground surface. Street
names shall be from a list compiled by the Town Board or as may be
approved by the Town Board. The travel way must be marked at each
intersection and every 500 feet or at the discretion of the Town Superintendent
of Highways.
A.
Concrete monuments; construction stakes. The applicant
shall establish and clearly mark on site the limits of street right-of-way
and easements with concrete monuments; and the center line and grades
of the finished road pavement and the location and elevations of drainage
structures as shown on the approved plans with construction stakes.
Such construction stakes shall be maintained at the applicant's expense
until the construction of road pavement, drainage structures, curbs,
sidewalks and shoulders have been completed, inspected and approved
by the Town Superintendent of Highways and the Town Engineer.
(1)
Location of concrete monument.
(a)
Permanent concrete monuments shall be set on
right-of-way lines of streets at all intersections and beginning and
end of streets. There shall be a clear view of adjacent monuments
on the right-of-way line. All monuments shall exist on completion
of the construction of the streets.
(b)
Permanent markers should be constructed in a
four-inch PVC pipe filled with concrete with a one-half-inch-diameter
steel rod at its center, or equivalent construction approved by the
Town Superintendent of Highways.
(2)
Certification. The applicant's engineer or licensed
surveyor shall certify that the location of all monuments is accurate
before acceptance of the street by the Town Board.
A.
Where surface water from streets must lead through
other than gutters and storm drains or existing stream channels, outside
the right-of-way, permanent drainage easements having a minimum width
of 30 feet shall be provided to a point where a natural watercourse
exists. In some cases this may include easements over property outside
the boundaries of the subdivision involved. Natural stream or ditch
channels shall have a minimum of thirty-foot-wide permanent easements
and be shown on the proposed plans of subdivision. All permanent easement
lines shall be monumented as a right-of-way.
B.
The right-of-way shall extend at least two feet beyond
the top of cut or toe of fill of any excavation or embankment shown
on the street plans.
A.
The applicant shall be responsible for clearing or
grubbing that portion of the proposed public right-of-way necessary
for construction of the required improvements, maintenance of sight
distances and installation of drainage improvements.
B.
At a minimum, a clear zone shall extend at least 10
feet from either edge of the travel way, a stream channel, or any
other portion of the public right-of-way or easement area as determined
by the Town Superintendent of Highways.
C.
All stumps, roots, boulders, walls and buildings shall
be excavated and removed from said clear zone. Those areas not otherwise
improved shall be graded and seeded according to the requirements
of the Town Superintendent of Highways.
A.
The applicant shall complete the shaping of the street
right-of-way, streams and ditches and easement areas to the line and
grade as shown on the approved plans and as otherwise may be directed
by the Town Superintendent of Highways. In the construction of the
roadway, all topsoil, loam, rocks and organic material shall be removed
until a satisfactory subbase is established. In areas to be filled,
all topsoil shall be excavated and removed. All fills shall be made
with acceptable material as approved by the Town Superintendent of
Highways. Such fills shall be made in layers of not more than 12 inches
each and properly compacted with a minimum weight ten-ton roller or
equivalent.
B.
The subgrade shall be shaped to line and grade with
no depressions. The subgrade shall be stable in all respects to the
satisfaction of the Town Superintendent of Highways and Town Engineer
before the foundation course is laid. No large stones or rock ledges
shall protrude into the foundation course.
C.
Before the foundation course is laid, all storm and
sanitary sewers and all utilities, including house connections for
existing and future homes, and hydrants, shall have been installed
to the satisfaction of the Town Superintendent of Highways and Town
Engineer.
D.
All slopes and sidewalk areas within the right-of-way
shall be graded before the foundation course is made and all loose
and exposed stone shall be removed. All slopes shall be fully stabilized
in a manner satisfactory to the Town Superintendent of Highways. The
procedures set forth in the New York Standards and Specifications
for Erosion and Sediment Control, latest edition, shall be adhered
to in the treatment of stabilized slopes and ditches. The minimum
treatment of areas in the right-of-way, not part of the roadway or
drainage system, shall be the application of red fescue and bluegrass
seed at the rate of eight pounds per 1,000 square feet with a mulch
of small grain straw at a rate of two tons per acre. Stabilization
treatment shall be accomplished within 14 days of soil exposure by
grading.
A.
Fabric stabilization. Approved nonwoven geotextile
fabric material shall be installed under the roadway foundation gravel
course whenever required by the Town Superintendent of Highways and
Town Engineer due to soil drainage conditions or wetness.
B.
Base course. The base course aggregate shall consist
of a minimum of nine inches of well-graded, uniformly mixed run-of-bank
gravel, or nine inches of well-graded, uniformly mixed broken stone,
hard shale, or crushed stone with a four-inch thick top leveling aggregate
base course of a uniformly graded crushed stone (NYSDOT Item 304,
or approved equal). All of the above shall be approved by the Town
Superintendent of Highways and Town Engineer.
(1)
The aggregate base course shall contain stones no
larger than four inches in thickness and be well-graded from coarse
to fine. No aggregate containing more than 5% chert as determined
by the Town Engineer may be used for surface treatment work. All materials
shall be of the required sizes when placed in the work, and breaking
up stone, gravel or slag by hammers or otherwise will not be permitted.
(2)
The aggregate base course material shall be placed
on the prepared subgrade in two layers, and each layer shall be thoroughly
compacted by rolling with a minimum weight ten-ton power-driven roller
or other equipment approved by the Town Superintendent of Highways
or Town Engineer. Any imperfections that may show up must be brought
up to an elevation parallel to, and at least equal to, the depth of
the required gravel base and pavement depth.
(3)
Leveling base course. After the aggregate base course is placed in suitably compacted, four inches of uniformly graded NYSDOT Item 304 crushed stone (aka "Item No. 4") acceptable to the Town Superintendent of Highways and the Town Engineer shall be placed over the entire width of the roadway. This material shall then be compacted with a ten-ton power-driven roller or other equipment approved by the Town Superintendent of Highways to present an even surface both longitudinally and transversely. To this surface will then be applied a wearing course of bituminous material. (Refer to § 138-39.)
(4)
The leveling base course shall be regraded and rolled
prior to paving as required by the Town Superintendent of Highways.
Stakes with final line and grade shall be maintained by the applicant
at all times to check the foundation courses as well as pavement.
(5)
Samples and testing.
(a)
All materials will be sampled and tested whenever
it may appear to be desirable. All materials must pass the soundness
test, plasticity index, elongated particles specification and other
materials specifications as prescribed by the current New York State
DOT or Dutchess County specifications. The cost of these tests will
be paid for by the applicant, who shall provide the Town Superintendent
of Highways with certified test results.
(b)
All material shall meet the specification prior
to placement on the grade. All processing shall be completed at the
source.
A.
Design. All drainage structures, ditches and culverts
shall be designed by a licensed professional engineer and shall provide
proper drainage conveyance capacities for at least the fifty-year
storm event.
(1)
All plans for any drainage structures and design computations
shall be submitted to the Town Superintendent of Highways and Town
Engineer for review and approval. Drainage calculations shall include,
but not be limited to, the entire drainage area (in acres) with the
description of both existing and proposed facilities, watershed maps
indicating ground cover, soil types and land slope, the runoff curve
number used in the Technical Release 55 modeling methodology, the
flow path and time of concentration factor, and the peak stormwater
discharge flow rate for pre- and postdevelopment conditions. When
a NYSDEC-administered Stormwater SPDES General Permit is required,
all drainage calculations for stormwater quantity and quality treatment,
when applicable, shall comply with the standards and criteria specified
in the NYSDEC's New York Stormwater Management Design Manual, latest
edition. The Town Board shall require a certification from the Town
Superintendent of Highways or Town Engineer as to compliance with
this subsection.
(2)
Erosion and sediment control (ESC) plans shall be
prepared and submitted for review for all projects that propose land
disturbance. Projects that disturb greater than one acre shall submit
plans that strictly comply with the NYSDEC's New York Standards and
Specifications for Erosion and Sediment Control, latest edition, as
required to comply with the required Stormwater SPDES General Permit.
In the event that a residential development project that proposes
to disturb greater than five acres, or a nonresidential development
that proposes to disturb one or more acres, a stormwater pollution
prevention plan (SWPPP) must be prepared and submitted for review
to the Town Engineer in accordance with the requirements of the NYSDEC-administered
Stormwater SPDES General Permit. No net increase in the peak rate
of stormwater discharge of postdevelopment conditions during the ten-year
and one-hundred-year storm frequency event when compared to predevelopment
site drainage conditions will be allowed for projects disturbing more
than one acre or in cases of lesser land disturbance proposals where
the Town Engineer determines that no increase is necessary due to
particular downstream factors and conditions of flooding or undersized
existing drainage facilities. This zero-net-percent-increase plan
will require the applicant to install devices or structures which
will restrict the stormwater runoff to its predeveloped condition.
Typically, this would involve the installation of detention basins,
infiltration facilities or similar measures.
(3)
Plans for any drainage structure other than pipe culverts,
when existing or proposed, shall be submitted in detail to the Town
Superintendent of Highways and Town Engineer for approval. The minimum
grade of any drainage pipe or culvert shall not be less than 0.75%,
unless specifically approved in writing by the Town Superintendent
or Town Engineer. The approved plans shall show invert elevations
of the inlet and outlet of all drainage structures. Any deviation
from the approved plans shall be only by the written approval of the
Town Superintendent of Highways and Town Engineer, in writing.
(4)
No culvert pipe which crosses a Town road shall be
less than 15 inches in diameter.
(5)
Where culverts are required for driveway crossings,
they shall have a minimum diameter of 12 inches and a minimum length
of 30 feet. If driveway culverts are required after roads have been
accepted by the Town, installation thereof shall be the responsibility
of and the cost shall be paid for by the party requesting such driveway.
The Town shall not be responsible for the installation of or payment
for said culverts.
B.
The width of the trench in which the pipe is laid
shall be sufficient to permit tamping of the backfill around the pipe.
A cushion of at least six inches shall be laid in line with grade
prior to laying the pipe. No rock over three inches' thickness shall
protrude or lay in this cushion. The soil below the cushion shall
be stable enough that there will be no settlement of pipe after backfilling
the trench.
C.
The pipe shall be laid to true line and grade on the
prepared bed of the trench. All connections for corrugated metal pipe
shall consist of twelve-inch corrugated metal bands lapping on equal
portions of the sections to be connected. All HDPE culvert pipe shall
use slip-on type joints. All reinforced concrete pipe culverts shall
use bell and spigot mastic joints or approved equal. Backfilling of
the trench shall be done with run-of-bank gravel or other suitable
material approved by the Town Superintendent of Highways and Town
Engineer. The backfill shall be placed in layers of no more than 18
inches which shall be properly compacted. In no case shall the top
of any drainage pipe be less than eight inches below the finished
grade of pavement.
D.
Capacity. All drainage structures shall be of a size
sufficient to carry natural water runoff and stormwater and also that
which, in the opinion of the Town Superintendent of Highways and Town
Engineer, may be reasonably anticipated from future construction both
from within the development and from adjoining properties which normally
drain across the area of the proposed development. Any new drainage
conveyance structure within the subdivision, excepting structures
that are designed to provide required stormwater detention, shall
generally be designed to accommodate at least a fifty-year storm.
Additional or larger culverts and drainage structures shall be installed
and paid for by the applicant if the Town Superintendent of Highways
and Town Engineer so direct.
E.
Runoff on adjoining owners. All drainage ditches shall
be constructed to provide for the flow as described above and easements
shall be acquired by the applicants and presented to the Town Board
in order to save the Town from claims of runoff on adjoining owners.
These easements shall carry runoff to a defendable line of drainage.
F.
Bridges. Bridges shall be constructed according to
the current specifications of the New York State DOT. The word "current"
as used in the preceding sentence means the date that the offer to
dedicate such road with a bridge or bridges upon it is presented to
the Town Board and/or Planning Board following approval by the Town
Superintendent of Highways and Town Engineer. Bridges shall be designed
by a licensed professional engineer, and design calculations shall
be submitted to the Town Superintendent of Highways and the Town Engineer
as outlined above.
A.
Catch basins and curb inlets shall be constructed
in order that surface water be intercepted. Such structures shall
be spaced at 400 feet or less. On grades in excess of 6%, the distance
apart shall not exceed 250 feet. Whenever, in the opinion of the Town
Superintendent of Highways and Town 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 Town Superintendent
of Highways and Town Engineer at any time prior to construction of
pavement.
B.
Structures may be precast or cast in place using 3,500
psi concrete and reinforced as required. Side throats shall be required
on catch basins for 6% or steeper ditch line slopes.
A.
Headwalls. Headwalls of concrete or mortared stone
masonry may be constructed at the outlet and inlet ends of the culvert
pipe when approved by the Town Superintendent of Highways. Culverts
shall extend to the toe of embankment. The bearing of all headwalls
shall have a solid base. If soft material is encountered, it shall
be removed and backfilled with run-of-bank gravel or other approved
aggregate material. A concrete mix of 3,500 psi after 28 days shall
be used. It shall be the responsibility of the applicant that no headwalls
shall crack or become tipped from settlement.
B.
End sections. Corrugated metal pipe end sections shall
otherwise be used at the inlet and outlet ends of culvert pipe where
required to prevent erosion or as directed by the Town Superintendent
of Highways and Town Engineer. End sections shall be designed and
installed to prevent piping, erosion and undercutting. End sections
shall be of a gauge in accordance with the New York State DOT specifications
for corrugated metal pipe end sections.
C.
Riprap ditches and embankments. When, in the opinion
of the Town Superintendent of Highways and Town Engineer, it is necessary
to place a protective covering of erosion-resistant material on embankment
slopes, streambanks, at culvert inlets or outlets, on bottoms and
side slopes of channels, at structure foundations, and at other locations
shown on the plans, the applicant shall install such covering as directed
by the Town Superintendent of Highways and Town Engineer.
(1)
Fabric material. Ditches shall be lined with nonwoven
geotextile fabric material as specified by the Town Engineer prior
to placing riprap to prevent vegetative growth.
(2)
Stone filling. Stone filling shall consist of well-graded
stone placed as protective material on streambanks, in channels and
elsewhere as required. The gradation of materials furnished for use
as stone filling shall be approved by the Town Superintendent of Highways
and generally meet the standard of 50% to 100% of total by weight
being individual stone sizes heavier than 100 pounds and no more than
10% of total by weight being smaller than four inches' diameter in
size. Materials shall contain a sufficient amount of stones smaller
than the average stone size to fill the voids between the larger stones.
(3)
Bedding material.
(a)
Bedding material shall consist of granular material
placed in a layer, where required, on the ground surface prior to
placing stone filling or riprap. The purpose of the bedding material
is to prevent underlying finer material from passing into and through
the stone filling or riprap.
(b)
Bedding material shall be composed of crushed
stone, crushed air-cooled blast furnace slag or gravel. It shall be
free of soft, nondurable particles, organic matter and thin or elongated
particles in excess of those approved by the Town Engineer.
(4)
Construction details. The ground surface on which
bank or channel protection is to be placed shall be free of brush,
trees, stumps and other objectionable material and shall be dressed
to a smooth surface. All soft or spongy material shall be removed
to a reasonable depth as directed by the Town Engineer and replaced
with approved material. Filled areas shall be compacted. Protection
for structure foundation shall be provided as early as the foundation
construction permits. Stone filling used for bank or channel protection
shall be placed to its full courses thickness in one operation, unless
otherwise directed by the Town Engineer. Rearranging of individual
stones by mechanical equipment or by hand will be required to the
extent necessary to secure the desired distribution. Where called
for on the plans, or directed by the Town Engineer, stone filling
and dry riprap shall be placed on bedding material. Contamination
of bedding material by natural soils or other materials shall be prevented
at all times.
If, in the opinion of the Town Superintendent
of Highways and Town Engineer, it is necessary to intercept and carry
away groundwater within the limits of the right-of-way, to protect
the stability of the road bed, curb or sidewalk areas, the subdrainage
required by the Town Superintendent of Highways shall be installed.
Perforated pipe or porous wall pipe having a minimum diameter of four
inches, encased in six inches of three-quarter-inch clean crushed
stone or crushed gravel, shall be used for such purpose in amount
deemed necessary by the Town Superintendent of Highways and Town Engineer.
Roof and cellar drains shall in no case be allowed
to flow into the street travelway. Drains from sanitary sewers or
septic tanks will not be permitted to flow into street ditches or
storm drains under any circumstances.
The grade of the street shall not be in excess
of 10% nor less than 0.75%. Upon the written approval of the Town
Superintendent of Highways and Town Engineer, the maximum grade of
the street may exceed 10% over limited distances (no more than 300
feet in length) to no more than a grade of 12% on low-volume, rural
residential and/or private roads due to extraordinary circumstances
and design considerations.

to the toe of slope. Slopes steeper than 2:1 with height of drop-off
more than four feet will require guide rail installation. Slopes less
than 2:1 having a height of drop-off more than 10 feet will be protected
with guide rail.
On suburban-type streets, six-inch-wide Portland
cement concrete curbs may be constructed on both sides of the street
as shown in Figure 4,[1] prior to laying street pavement to the dimensions and
specifications shown. A base course of four inches of run-of-bank
gravel, tamped and free of stone over two inches in thickness, shall
be laid under all curbing. A concrete mix of 3,500 psi after 28 days
shall be used and shall be finished and cured to the satisfaction
of the Town Superintendent of Highways and Town Engineer. The applicant,
at his or her own expense, shall replace any curbing that has settled,
cracked, scaled or has become damaged in any way by the applicant
before and within the one-year maintenance period after dedication.
Curbs shall be depressed four inches at all driveways. Stone curbs
or precast curbs may be substituted on approval of the Town Superintendent
of Highways and Town Engineer.

Paved gutters shall be constructed on rural streets
whenever the slope of said street shall be 6% or greater, or when
in the opinion of the Town Superintendent of Highways and Town Engineer
said gutters are required to handle present or future storm runoff.
The paved gutter shall be constructed on both sides of the street.
B.
Such paved gutters shall be considered as part of
the construction of shoulders after the street pavement has been laid.
Grading of shoulders and paved gutters shall be simultaneous, being
shaped and rolled just prior to the application of double surface
treatment for shoulders and paved gutters. The grades on paved gutters
shall be maintained relative to the center line elevation to ensure
good runoff of surface water. It should be noted that the foundation
course of the street pavement extends to the outer edge of the paved
gutter.
A.
All intersections with existing Town or county roads
shall be constructed with the edge of pavement having a radius of
25 feet maximum. All intersections shall be at right angles unless
an exception for good cause has been granted and a written waiver
of these specifications has been issued by the Town Superintendent
of Highways and Town Engineer.
(1)
Intersections within the development shall be constructed
with edge of pavement having a radius of 20 feet minimum and 25 feet
maximum. All intersecting streets shall have a minimum horizontal
sight distance of 250 feet in each direction. Exceptions for less
than 250 feet shall be in writing and approved by the Town Superintendent
of Highways and Town Engineer. In no case shall the safe sight distance
be less than the distance calculated using "A Policy on Geometric
Design of Highways and Streets, 1984" by AASHTO and "Policy and Standards
for Entrance to State Highways" by New York State DOT. The applicant
may be required to remove embankments and/or vegetation outside of
the proposed right-of-way in order to satisfy the safe sight distances.
(2)
Where a development street intersects a Town or county
road, the approved plans will show the proposed type, length and diameter
of pipe and drainage flow along said road. The pipe will be installed
and paid for by the applicant under the direction of the Town Superintendent
of Highways and Town Engineer, or the County Superintendent of Highways
or his or her representative, as the case may be.
(3)
The grade of the intersecting street with a Town or
county road shall be no more than 3% from the edge of the shoulder
of the Town or county road for a distance of 40 feet on the right-of-way
or road line of said road. The County Superintendent of Highways shall
be notified of all intersections with county roads, for approval of
location, grade and drainage structures.
B.
Intersections of suburban streets by other streets
shall be at least 800 feet apart. Cross (four-cornered) street intersections
shall be avoided, except at important traffic intersections. A distance
of at least 150 feet shall be maintained between offset intersections.
Within 40 feet of an intersection, streets shall be approximately
at right angles, and grades shall be limited to 1 1/2%, and right-of-way
boundary curves of at least 25 feet in radius shall be provided at
the property line.
C.
Within the triangular area formed at corners by the
intersecting street lines, for a distance of 75 feet from their intersection
and diagonal connecting the end points of these lines, visibility
for traffic safety shall be provided by excavating, if necessary.
Nothing in the way of fences, walls, hedges or other landscaping shall
be permitted to obstruct such visibility. An easement for the enforcement
of this provision shall be granted to the Town of Stanford.
After the foundation course has been inspected
and approved by the Town Superintendent of Highways and Town Engineer
and the six-inch gravel leveling course has been thoroughly compacted
and trimmed to present an even surface, both in profile and cross
section, and allowing for the required depth of finished pavement,
the following type of pavement shall be laid under the supervision
of the Town Superintendent of Highways:
A.
