E.
Intersections. Intersections of major streets by other
streets shall be at least 800 feet apart, if possible. Cross (four-cornered)
street intersections shall be avoided, except at important and higher-volume
traffic intersections. A distance of at least 150 feet shall be maintained
between offset intersections. Within 100 feet of an intersection,
streets shall be approximately at right angles, and grades shall be
limited to 3%. Street intersection corners shall be rounded at the
property line by curves having a radius of 35 feet for major and secondary
thoroughfares and 25 feet for local streets. Edges of pavement and
curbs at intersections shall have curves concentric with property
line curves. At intersections of local streets with thoroughfares,
the requirements for thoroughfares shall govern. Within the triangular
area formed at corners by the intersecting street lines, for a distance
of 75 feet from their intersection and the 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. Deeds for corner lots at street intersections shall
have covenants included therein prohibiting the planting or construction
of obstructions to visibility within the triangular area described
above.
Streets shall be constructed in accordance with
the following standards and procedures:
A.
Clearing and grubbing.
(1)
All trees, perishable matter, boulders, structures,
fences and debris of whatever nature shall be cleared from the full
width of the roadway section, including both cut and fill slopes,
except that trees located not closer than three feet from the edge
of pavement may remain subject to the approval of the Superintendent.
All roots and stumps within the limits of the road section shall be
grubbed and excavated, except that no grubbing will be required where
the finished roadway surface will be six feet or more above the original
ground surface where foundation soil is satisfactory. Where trees
are cleared and grubbing is not required, the trunks shall be cut
off flush to the ground if possible, and in any instance not more
than six inches above the ground.
(2)
Specially designated trees or other objects which
have been designated to remain within the right-of-way shall be protected
and preserved by whatever means necessary to ensure that no damage
will be incurred during the construction.
(3)
At intersections and on curves additional clearing
may be necessary to provide adequate visibility.
(4)
This work shall all be as approved by the Superintendent.
B.
Topsoil. Topsoil shall be stripped from all surfaces
of the roadway area which will be disturbed by the cut or fill operation.
Topsoil so stripped shall be stockpiled on the site and shall be reserved
for roadway landscaping unless approval for other usage has been granted
by the Superintendent.
C.
Subgrade.
(1)
The subgrade shall be brought to the required grade
by excavation or filling.
(2)
The subgrade material in cuts or fills shall be excavated
or placed as the case may be so that the compacted and shaped subgrade
surface is at least 19 inches below the finished grade of the proposed
pavement surface.
(3)
All objectionable materials, including soft clays,
muck, peat and organic material lying below the proposed subgrade
elevation within the paved area of the roadway shall be excavated
to good bottom and replaced by crushed stone, gravel or other approved
granular material.
(4)
Excavated material, if suitable, may be used in forming
embankments.
(5)
Rock, when encountered, shall be removed to the slopes
and lines shown on the Standard Details contained herein or as directed
by the Superintendent.[1] Excavated rock shall be replaced with suitable material
in a manner that will provide a compacted earth layer to a minimum
thickness of 12 inches below the subgrade surface and at least eight
inches below the bottom of pipes, conduits, cables, drainage structures
or manholes. Blasting shall be performed only by licensed, competent
personnel. Blasts shall be properly covered and safety measures observed,
all in accordance with the Safety Code of the State of New York governing
storage and use of explosives, § 764, Subdivision 3, of
the General Business Law, as amended, and all other pertinent laws,
ordinances or codes. Insurance coverage shall be as required, and
proof of adequate insurance shall be presented to the Superintendent
prior to commencement of any blasting work.
[Amended 6-16-1998]
[1]
Editor's Note: The Standard Details are included
at the end of this chapter.
(6)
The subgrade shall be constructed by rolling, shaping
and such rerolling and reshaping and removal and replacement of unsuitable
material causing soft spots as required to provide a uniform, stable,
dense surface properly crowned to drain water laterally to the roadway
edges.
(7)
Where an embankment is required, the fill shall be
spread in layers not to exceed six inches in depth, loose, bladed
to an even surface free from clods and compacted by rolling with an
approved power roller. Boulders or rock fill shall not be deposited
within two feet of the finished subgrade elevation. Areas not accessible
to the power roller, such as in the vicinity of catch basins, manholes,
culverts, underground utilities and the like, shall be adequately
compacted by approved mechanical hand tampers. Filling, compacting
and shaping operations shall continue alternately until the roadway
section, free of all soft spots, both cut and fill, conforms in all
respects to the lines and grades shown on the approved construction
plans and to the standards contained herein.
(8)
Crushed stone or gravel may be substituted for earth
fills if specifically approved by the Superintendent.
(9)
Smooth steel wheel rollers, when approved, shall have
a minimum weight of 10 tons. Rollers of other types shall be as approved
by the Superintendent.
(10)
Approval of the subgrade elevations must be
obtained prior to the installation of any underground utility.
D.
Base course. The base course shall be constructed
to the lines, grades and typical cross section as shown on the approved
plat and construction plan and to the Standard Details contained herein.[2] The thickness of the base course after compaction shall
be 12 inches. All material shall be approved by the Superintendent.
(1)
Materials. All materials used in the construction
of the base course shall consist of selected sand, gravel and soil
binder, free from injurious quantities of flaky materials. The particles
shall be well graded from coarse to fine and of such size as will
pass a two-inch-square sieve, 30% to 65% by weight shall pass the
one-fourth-inch-square sieve and not more than 10% by weight shall
pass a No. 200 sieve. Particles passing a No. 40 mesh sieve shall
have a plasticity index of zero.
(2)
Construction. No segregation of large or fine particles
will be allowed, but the material as spread shall be well graded with
no pockets of fine material, and the thickness of any layer shall
have a maximum depth of six inches after compaction. Water shall be
added in such amounts as the Superintendent may consider necessary
to secure satisfactory compaction. When the moisture content of the
layer is within the limits for proper compaction, the entire surface
shall be rolled with a smooth wheel roller having a minimum weight
of 10 tons. After compaction, the course shall be tested with a straight
edge 16 feet in length, and any depression over 1/4 inch shall be
eliminated by the use of the same material and the surface rerolled.
In all cases, this course must be so thoroughly compacted that it
will not weave under the roller.
[2]
Editor's Note: The Standard Details are included
at the end of this chapter.
E.
Surface course. The penetration macadam surface course
shall be composed of broken stone and bituminous material applied
by the penetration method. It shall be constructed on the prepared
base course in conformity with the lines, grades, compacted thickness
and typical cross section shown on the plans. The thickness of the
surface course after compaction shall be five inches. All materials
shall be approved by the Superintendent.
(1)

(b)
Bituminous materials used for this course shall
meet the requirements of New York State Department of Public Works.
Specifications of January 2, 1972, for asphalt emulsions, Grade MS-2h.
(c)
No bituminous material shall be applied at any
time without the approval of the Superintendent.
(2)
Construction.
(a)
Upon a prepared subgrade, coarse aggregate conforming
to Gradation 3 shall be spread in the required amount by approved
mechanical spreaders to a uniform depth and true to line and grade.
(b)
No stone with a dust coating will be permitted
for use in this course. If any stone spread for this course becomes
wet or dirty, it must be allowed to dry to the full depth of the course,
and dirty stone removed and replaced with clean stone before the spreading
of bituminous material proceeds. The coarse aggregate shall be dry
rolled with a self-propelling roller weighing approximately 10 tons,
until compacted and keyed. Rolling shall progress gradually from the
sides to the center parallel to the center line of the road and shall
continue until the aggregate does not creep or wave ahead of the roller.
(c)
After the coarse aggregate has been thoroughly
compacted, bituminous material, heated to a temperature between 75°
F. and 170° F., shall be evenly spread over the surface by the
use of an approved pressure distributor, operating under a pressure
of 50 pounds per square inch or more as the Superintendent may direct.
The quantity of bituminous material used in the first application
shall be 2 1/2 gallons per square yard, or as directed by the
Superintendent.
(d)
Immediately following the application of bituminous
material, key aggregate conforming to Gradation 1 shall be spread
evenly over the surface until the voids are filled. Rolling of the
surface shall start immediately after spreading while the bituminous
material is still warm and shall continue until the course of stone
is thoroughly compacted and its surface is true and even to the established
grade.
(e)
After this portion of the work shall have been
completed, all loose stones shall be swept from the surface.
(f)
After the penetration course has been completed
and thoroughly cleaned of foreign material, a tack coat of asphaltic
emulsion shall be applied to the surface at the rate of 1/10 gallons
to 1/20 gallons per square yard. The tack coat shall be required in
all cases unless specific approval for omitting this requirement has
been granted by the Superintendent. A final wearing course of fine
bituminous concrete shall be uniformly spread by a self-propelling
mechanical spreader equipped with tamper bars and heating unit in
sufficient depth as to provide a finished compacted thickness after
rolling of not less than two inches. The fine wearing course in place
shall be thoroughly compacted with a two- or three-wheel tandem roller
weighing approximately 10 tons.
(g)
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.
(h)
The aforementioned top course bituminous concrete
wearing course shall be constructed conforming to the New York State
Department of Public Works Specifications of January 2, 1973, or as
amended, for hot-mix asphalt concrete pavement, Section 403.
G.
Slopes. Cut or fill sections beyond the sidewalk area
shall not be steeper than one unit vertical to 1 1/2 units horizontal
except in rock. The Superintendent may require a decrease in the amount
of slope to whatever extent necessary to maintain the stability of
the bank under the particular soil conditions. All earth slopes and
areas that have been disturbed in any way due to construction of the
road shall be covered with a minimum four inches of topsoil and suitably
seeded or planted with perennial rye grass to prevent erosion. The
Superintendent may require the removal of or adjustment of slopes
adjacent to intersections in order to assure adequate sight distance
at the intersection. Excess excavated material may be used to flatten
slopes as approved by the Superintendent.
Storm drainage shall be designed in accordance
with the following standards:
A.
Pipe.
(1)
Sufficient pipe shall be installed within the subdivision
to carry existing watercourses and to drain the proposed roads and
roads which may reasonably be expected to be constructed at some future
date on adjoining property which normally drains across the area of
the proposed subdivision. If, in the judgment of the Superintendent,
there will be no substantial danger from soil erosion or danger to
the public health and safety, the Superintendent may permit the discharge
of stormwater and established watercourses in open ditches across
proposed lots of 40,000 square feet or larger. All pipe shall be of
such diameter, not less than 15 inches, as will be sufficient to properly
carry stormwater expected to enter the pipe from the proposed subdivision
and from other properties, when developed, which normally drain across
the area of the proposed subdivision.
(2)
Storm sewers shall be designed to safely carry loads
resulting from storms of the maximum intensity which can be expected
to occur on an average of once in 10 years without being surcharged.
Culverts crossing under existing or proposed public streets shall
be designed to accommodate flows resulting from storms of the maximum
intensity which can be expected to occur on an average of once in
25 years without causing flooding of the roadway or adjacent properties.
B.
Method of design. The following criteria are intended
to act as a guide for engineers designing storm drainage facilities
for installation in the Town of Southeast. They are intended to indicate
the minimum acceptable stormwater runoff quantities. Special conditions
may warrant the use of more stringent design criteria.
(1)
Stormwater flows may be computed by use of the Rational
Method or by use of the methods described in the U.S. Soil Conservation
Service publications SCS-TP-149 and Technical Release No. 55.

The designer should contact the Town Engineer early
in the preliminary design to discuss what method or methods shall
be used in the design of storm drainage facilities.
C.
Manholes. Manholes shall be provided at each change
of slope or alignment, at all junction points and otherwise at intervals
in general not greater than 400 feet apart.
D.
Catch basins. Catch basins shall be provided in order
that surface water will not travel excessive distances without interception.
Catch basins will be provided generally in accordance with the following
schedules:
E.
Underdrains. The installation of underdrains will
be required beneath the edge of pavement of a proposed street wherever
the groundwater is known to be less than three feet below the proposed
finished grade of the street. The Superintendent may require underdrains
to be installed where localized seeps or springs are observed within
the proposed street lines.
F.
Headwalls, endwalls and erosion protection. Suitable
headwalls, endwalls and channel erosion protection shall be provided
at the open end of any pipe.
G.
Culverts. Culverts under streets shall have a minimum
diameter of 24 inches and shall be extended to the edge of the right-of-way
of the street unless otherwise permitted by the Superintendent. The
minimum driveway culvert diameter shall be 15 inches.
H.
Discharge. The discharge of all stormwater shall be
into streams, rivers or Town drains with adequate capacity to carry
the additional water. Where the discharge of stormwater shall be into
or through private property, proper easements and discharge rights
shall be secured by the applicant for the Town before approval of
the drainage plan. Paved ditches or gutters, where required, shall
be in accordance with details and dimensions shown in Standard Details.[1]
[1]
Editor's Note: The Standard Details are included
at the end of this chapter.
The storm drainage system shall be constructed
in accordance with the following standards and procedures:
A.
Pipe. Pipe generally shall be standard reinforced
concrete sewer pipe conforming to ASTM Designation C-76. The groove
end shall be so constructed that the tongue end shall be seated to
the full depth of the tongue. Joints shall be watertight. In special
instances where a portion of the storm drainage system is located
outside the roadway area, approval may be granted by the Superintendent
to allow metal pipe to be used. Metal pipe so allowed shall be bituminous-coated,
galvanized corrugated metal with paved invert or aluminum of the size
and gauge indicated on the approved construction drawings and shall
be provided with metal end sections where required.
B.
Catch basins and manholes. Catch basins and manholes
shall be constructed in accordance with the dimensions and details
shown on the Standard Details.[1] Catch basins shall be located in conformance with § A143-4D herein. On steep slopes or in special drainage situations, the Superintendent may require catch basins to be depressed and/or set back from the street curbline to facilitate the collection of water and may require the furnishing and installation of double inlets.
[1]
Editor's Note: The Standard Details are included
at the end of this chapter.
C.
Construction procedures. All pipe shall be laid to
line and grade as shown on the approved construction drawings. Line
and grade stakes shall be maintained in good order until the work
has been inspected and approved by the Superintendent.
D.
Bedding and backfill.
(1)
All pipe shall be properly bedded for its entire length
in accordance with the details and dimensions shown on Standard Details.[2] The material used for backfill shall generally be granular
material except where less permeable material is deemed desirable.
In all cases the type and quality of the backfill material shall be
approved by the Superintendent prior to placement. All backfill shall
be placed in layers not to exceed six inches in depth after compaction
and shall be thoroughly compacted by approved mechanical rammers,
vibrators or pneumatic tampers. Material placed immediately adjacent
to the pipe shall be deposited on both sides to approximately the
same elevation at the same time. Material shall not be deposited in
back of headwalls until all material in front of these structures
has been entirely placed and compacted. Special care shall be exercised
in placing and compacting material immediately adjacent to the pipe
to avoid damage to either the pipe or its alignment. Any pipe that
is damaged or moved out of alignment regardless of cause, will not
be accepted.
[2]
Editor's Note: The Standard Details are included
at the end of this chapter.
(2)
All drainage piping and appurtenances shall be completed
and backfilled before the roadway base course is placed.
To the extent practicable, electric and communication
cable shall be installed in the same trench. The trench generally
shall be 36 inches deep, but in no case shall the minimum cover below
subgrade be less than 18 inches. (In general, cable installed by New
York State Electric and Gas Corporation or New York Telephone is of
the direct-burial type.) In locations where cable passes below pavement,
an empty conduit shall be installed to allow replacement or additional
cable to be installed without pavement removal. Direct-burial cable
and conduit shall be installed with a sand cushion and cover extending
at least six inches all around. The installation shall conform in
all respects to the requirements as shown on the Standard Details.[1] All the applicable requirements of the State of New York Public Service Commission concerning underground extensions for new residential subdivisions shall be met. Excavation and backfill of the utility trench shall be completed and compacted prior to placing the roadway base course. Compaction efforts shall be as outlined hereinbefore in § A143-5D. Advance notice of at least 72 hours shall be given to the Town prior to commencement of installation of underground utilities.

shall be 3 1/2 feet long with four one-eighth-inch reinforcing
rods and set on the street line.
Guideposts and guide railings shall be installed
where shown on the approved construction drawings and/or as directed
by the Superintendent. Guideposts shall be required on any roadway
section constructed on an embankment which places the roadway surface
five feet or more above the existing ground surface from the toe of
the embankment where the slope of the embankment is steeper than four
feet horizontal to one foot vertical. Guide railing may be required
in certain locations that require greater protection. The installation
of guideposts or guide rails shall be in accordance with the dimensions
and details shown on the Standard Details.[1] Surface-dried redwood, red cedar, cypress or black locust
may be used untreated. Other lumber, including Douglas fir, pine,
oak, birch, maple and beech may be used but shall be subjected to
a pressure creosote treatment to a final retention of eight pounds
per cubic foot of wood by the empty-cell process. Posts shall be spaced
six feet on center where only posts are used and 10 feet on center
where the guide rail is used.
[1]
Editor's Note: The Standard Details are included
at the end of this chapter.
Street trees shall be planted on both sides
of any street. Trees shall be spaced approximately 100 feet apart,
subject to variations made necessary by driveways, street corners
and walks, and shall be located three feet from the edge of the pavement.
Trees to be planted shall be a caliper of 1 3/4 inches or larger
and shall have a minimum height of 10 feet. The kind of tree shall
be subject to the approval of the Superintendent and shall not include
evergreens, low branching trees, trees which are disease-bearing or
cause damage to sewers or trees which create a hazard to traffic or
pedestrians. Where the trees may interfere with utility poles and
wires or may restrict the required sight distance of a street, the
Superintendent may permit the location of required trees within the
front 10 feet of the proposed lots. Trees shall be planted in an approved
manner and in accordance with Standard Details. Existing trees along
the proposed streets which conform to these requirements may be substituted
for new trees. Tree wells, if required for trees that have been designated
to remain, shall be constructed in accordance with the Standard Details.[1]
