[HISTORY: Adopted by the Town Board of the Town of Wawarsing 5-3-2012 by L.L. No.
6-2012. Amendments noted where applicable.]
GENERAL REFERENCES
Streets and sidewalks — See Ch. 93.
It is the purpose of these specifications to establish minimum
acceptable standards of road construction for subdivisions and site
plans in the Town of Wawarsing, which requirements and standards must
be met and paid for by the person or firm proposing that the Town
take over such road as a Town road or recognize the road as a private
road. These specifications include but are not limited to width, design,
drainage, construction of base, pavement, curbs and sidewalks. Dedication
of the right-of-way will not be accepted until the engineer designated
by the Town Board as responsible for the observation of construction
has certified to the Town Board in writing that the construction of
the street or road has been completed in accordance with the approved
plans and specifications that follow, and that the total right-of-way
areas have been cleared of all debris and all construction completed
in a workmanlike manner. When new road rights-of-way are offered to
the Town for dedication, two copies of the record plan (as-built)
and deed with the description of the right-of-way shall be submitted
to the Town Engineer and the Town Superintendent of Highways for approval.
In his written certification, the Town's professional engineer
shall state that they, he, or his authorized representative has observed
all phases of the construction, and that all work has been completed
in general accordance with the approved plans and specifications.
A.
A plan of the proposed street shall be prepared by a qualified professional
engineer or qualified land surveyor licensed by the State of New York.
The plan shall clearly define the limits of the proposed right-of-way
by metes and bounds and shall include the location, widths, profiles
and grades of the proposed roadway, storm drainage, including culverts
and other drainage structures, and the locations of all easements
and utilities. The plans shall also include the owner of the property
and the name of the developer, if other than the owner. One copy each
of the plans shall be submitted to the Town Highway Superintendent
and Town Engineer at the time of application to make such road a Town
road, and to the New York State Department of Transportation or Ulster
County Department of Public Works when said proposed street drains
toward, intersects or may otherwise affect a state or county highway.
As applicable, the plans shall be submitted to the Town Planning Board
for review and approval under the applicable subdivision regulations
of the Town. Such roadway must not be subject to any right or easement
to others, which will in any way interfere with its use as a road
at all times. Such roadway must be granted to the Town by a full covenant
and warrantee deed containing the correct metes and bounds description
as shown on the approved map, which deed must be in such form as may
be required to entitle the same to be recorded in the office of the
County Clerk of Ulster County, and the filing fees must be paid by
the applicant.
B.
When required, permanent and temporary easements must be furnished
in said deed granting to the Town the right 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 outlets and easement will carry such water.
A minimum of 30 feet width of easement shall be required for the maintenance
of said easements of stormwater, water or sewer improvements.
C.
The proposed roadway must be constructed to conform to the minimum
requirements set forth below. The minimum width to be cleared shall
include all trees, rock formations, buildings, walls and any such
things that would endanger those using such roadway. The removal of
such obstructions shall be borne by the person or firm proposing such
road.
D.
Alteration of approved plans. Plans submitted shall not be altered
or amended after having been approved by the Town unless an amended
plan is resubmitted and approved. However, the developer, at his own
expense, shall provide additional storm drainage facilities or utilities
as may be ordered by the Town if, during the course of construction,
in the opinion of the Town Highway Superintendent, the Town Engineer
and/or the County Department of Public Works and New York State Department
of Transportation, such additional structures or facilities are necessary
to prevent any need for future pavement, future maintenance of right-of-way
or welfare and safety of the public, except that the Town Planning
Board may vary the requirements of such an order where there are practical
difficulties in the way of carrying out to the letter of such order;
unless such variance conflicts with the provisions of a Town or county
Official Drainage Map, in which event, the Official Map shall prevail.
If construction of said road 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. If these specifications
are amended prior to the start of construction, the developer will
be required to comply with updated requirements, unless waived by
the Town.
The provisions of this chapter supersede all prior regulations,
specifications and ordinances covered by the subject matter of this
chapter.
A.
Prior to the start of construction of any street, or prior to a stamp
of approval in the case of applications before the Planning Board,
the developer shall deposit with the Town a performance guarantee
in the form of cash or a letter of credit. The amount of the guarantee
shall be equal to 100% of the cost of all improvements as estimated
by the Town Engineer and approved by the Town Board. The amount shall
be determined by applying to the quantities or dimensions shown on
the approved plans the rates per unit as established by the Town Engineer
based on prevailing municipal construction costs at the time of approval.
B.
Within two years from the approval of the proposed subdivision by
the Planning Board, the developer shall complete all construction
within the right-of-way, including roadway, shoulders, curbs, if any,
gutters, storm drainage, etc., for each lot in accordance with the
approved plans and these specifications; and the developer shall adequately
document that all claims for labor and materials in connection with
said construction have been paid in full prior to offering said road
for dedication to the Town.
C.
If said construction is not completed to the satisfaction of the
Town within this period, the developer shall, subject to the approval
of the Town Board, maintain the performance guarantee in full effect
until the work is completed. Should the developer fail to obtain such
approval and/or allow the performance guarantee to lapse, the approval
to construct the improvements and the Planning Board approval shall
be considered void until such time that a new performance guarantee
acceptable to the Town has been established.
D.
Upon certification by the developer's professional engineer
or qualified licensed land surveyor, a submission of a record drawing
(as-built plan) and acceptance by the Town Highway Superintendent
or Town Engineer that the construction of the street has been completed
in accordance with the approved plans and specifications, the developer
will offer to the Town Board for dedication the completed street and
all other related improvements for public use free and clear of the
liens and encumbrances. This guarantee of dedication shall apply to
the owner of the property as well as the developer, where the two
are not synonymous.
E.
F.
Maintenance bonds. Prior to acceptance by the Town of the dedication of the street as guaranteed by § 69-5, Performance guarantee, above, the developer shall deposit with the Town Clerk a maintenance bond of acceptable surety or shall deposit with the chief fiscal officer of the Town acceptable negotiable government bonds, cash or certified check drawn upon a national or state bank, payable on its face to the Town of Wawarsing, guaranteeing that, for a period of two years from the date of acceptance of the dedication of the street and other improvements by the Town, the developer will maintain the street and other public utilities and improvements to the standard of construction set by these specifications, normal wear and tear excepted. This shall be interpreted to mean that the developer will, at his own expense, repair and make good any defects or damage which may develop during this maintenance period as a result of faulty construction within the right-of-way or as a result of other construction by the developer outside the right-of-way. During the maintenance period, the Town shall be responsible for snow and ice control, street cleaning of culverts and catch basins and other work of a familiar routine nature, provided that such work has in no way been caused by the developer's operations.
G.
The amount of the maintenance bond shall be at least equal to 10%
of the original amount of the performance guarantee. Subsequent to
the dedication of the street and after receipt of the maintenance
bond, the Town Board shall release the performance guarantee.
The Town Planning Board and Planning Board Engineer shall determine
and designate into which of the following classifications each proposed
subdivision street falls on the basis of the criteria hereinafter
set forth:
The following criteria shall be used to determine what classification
shall be given to a street.
Design standards for new streets and driveway are as follows:
B.
Sight distance requirements. All street and driveway intersections
shall meet the standards contained in the New York State Department
of Transportation publication entitled, "Policy and Standards for
Entrances to State Highways" (February 1998) or latest edition. More
specifically, said intersections shall, at a minimum, meet the intersection
sight distance (ISD) requirements in Tables 3 and 4 of said publication.
Notwithstanding the above, driveways which cannot meet the ISD requirements
shall, at a minimum, meet the stopping sight distance (SSD) requirements
in Table 5 of said publication.
C.
Intersections.
(1)
Intersections of major streets shall be at least 80C feet apart,
if possible. Cross (four cornered) street intersections shall be avoided
insofar as possible, except at important traffic locations. A distance
at least equal to the minimum required lot width, but not less than
200 feet, shall be maintained between center lines of offset intersecting
streets. Within 60 feet of the center of an intersection, streets
shall be at approximately right angles and grades shall be limited
to 2%. Wherever two streets intersect at an angle of less than 75º,
special pavement, channelization, right-of-way and/or sight easement
restrictions may be required.
(2)
All intersections with existing Town, county, or state roads shall
be constructed with the edge of pavement having a radius of 30 feet
minimum.
D.
Grades and vertical curves.
(1)
The grades of the streets and vertical curves shall be in accordance
with the Table Of Design Standards For New Streets.[1] Grades shall be limited to no more than 2% within 60 feet
of the center of an intersection.
[1]
Editor's Note: The Table of Design Standards for New Streets is included at the end of this chapter.
(2)
Changes in grade. All changes in grade shall be connected by vertical
curves of such length and radius as meet with the approval of the
Town Engineer so that clear visibility shall be provided for a safe
distance as well as a smooth transition.
(3)
In order to provide visibility for traffic safety, that portion of
any corner lot (whether at an intersection of a new street or an existing
street), shall be cleared of all growth (except isolated trees) and
obstructions above the level 30 inches higher than the center line
of the street for a distance of 75 feet from the center point of the
intersection. If directed, ground shall be excavated to achieve visibility.
(4)
Curve radii. In general, street lines within a block deflecting from
each other at any one point by more than 10° shall be connected
with a curve, the radius of which for the center line of the street
shall not be less than in the Table of Design Standards For New Streets.[2] The outer street line in each case shall be parallel to
such inner street line.
[2]
Editor's Note: The Table of Design Standards for New Streets is included at the end of this chapter.
E.
Culs-de-sac (dead-end streets). Culs-de-sac shall be equipped with
a turnaround roadway with a minimum diameter of right-of-way and a
minimum outside diameter of traveled way as shown in the Table of
Design Standards for New Streets (detail located in appendix).[3] The radii of the curves entering into, and exiting from,
the cul-de-sac shall be a minimum of 50 feet. Culs-de-sac shall be
graded to allow for positive drainage to the curb lines. The minimum
grade through the cul-de-sac, as determined along the curb line, shall
be 1%. The maximum grade through a cul-de-sac, as determined along
the curb line, shall not exceed 5%. A twenty-foot-by-twenty-foot snow
storage easement shall be provided at the end of a cul-de-sac.
[3]
Editor's Note: The Table of Design Standards for New
Streets, and details as contained in Figures 1 through 11, are included
at the end of this chapter.
F.
Driveways.
(1)
Developers and home builders shall design and construct all driveways
within the limits of the right-of-way with sufficient sight distance
(in both directions) and with a positive five-percent grade from the
curb to the right-of-way line or from the street pavement line (where
no curb exists) with a negative two-percent grade for the first 10
feet. The minimum width of the driveway pavement at the curb or street
pavement line shall be 15 feet, tapering to a minimum of 10 feet at
the right-of-way line. All driveways shall have a six-inch run-of-bank
gravel foundation course from the curb to the right-of-way line and
no less than three inches of hot-mix asphalt concrete top course from
the curb or street pavement line to a point 25 feet from the curb
or street pavement line, which shall be applied during or after the
laying of the street pavement.
(2)
Grading shall be to the satisfaction of the Town Highway Superintendent
and the Town Engineer prior to the surfacing of such driveways. The
maximum allowable driveway slope shall be 10%. Where required by the
Town Highway Superintendent, a culvert or drainage system shall be
provided, with the pipe size and material to be as acceptable to the
Town Highway Superintendent. Pipe size shall not be less than 15 inches
in diameter, and shall have a minimum coverage of 12 inches over the
pipe.
(3)
All driveways that have received a waiver from the Planning Board
to allow any portion of said driveway to have a slope over 10%, which
in any case may not exceed 12%, shall be paved for the entire length
of the driveway.
(4)
All driveways that exceed 250 feet in length must provide a turnaround
area sufficient for emergency vehicles as well as provide at least
one area of the driveway that is wide enough for two emergency vehicles
to simultaneously pass one another.
The developer shall establish and clearly mark on the site the
limits or road rights-of-way and easements with monuments, and grades
of the finished road pavement, and the locations and elevations of
drainage structures, as shown on the approved plans, with constructions
stakes. Such construction of road pavement, drainage, structures,
curbs, and shoulders shall be completed, inspected and approved by
the Town Highway Superintendent and the Town Engineer at each step
of construction. The developer shall be responsible for scheduling
the work so as to coordinate all necessary inspections. Monuments
shall be set on right-of-way lines of streets at all intersections,
angle points, points of curvature, lot line front corners, beginning
and end of streets, and at three points of all culs-de-sac. 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. The monuments shall be made of concrete with minimum dimensions
of 30 inches long, four inches square top and six inches square bottom,
with a one-half-inch drilled hole in the top or a galvanized iron
FENO drivable anchored survey marker 24 inches long with a polyroc
monument block. Concrete monuments shall have a No. 3 rebar in the
center of it for ease of future location. If a monument should be
located in a rock edge, the surface shall be stripped and a one-half-inch
steel rod drilled into the ledge. Monuments shall be installed flush
with the final graded surface. The developer's licensed surveyor
shall certify that the location of all monuments is accurate before
acceptance of the street by the Town Board.
A.
Drainage easements. Where surface water from a road must lead through
storm drains, ditches, swales 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,
if required by the Planning Board or the Town Highway Superintendent
and be shown on the proposed plans of a subdivision. All permanent
easement lines shall be monumented as a right-of-way.
B.
Sight easements. Sight easements shall be provided across all road
corners, outside the road right-of-way, within the triangular area
formed by the nearest edges of street pavement and a straight line
between two points each 25 feet back from the theoretical intersection
of the edges of such pavement prolonged. The easements shall provide
that the holder of fee title to the abutting streets shall have the
right to enter the easement area for the purpose of clearing, pruning
or regrading so as to maintain a clear line of sight in either direction
across such triangular area between an observer's eye 3.5 feet
above the pavement surface on one street and an object one foot above
the pavement surface on the other. The initial establishment of clear
sight lines within the sight easement area shall be the responsibility
of the subdivider.
A.
Prior to commencement of work, the developer shall have all roads
and easement areas staked and shall meet with the Town Highway Superintendent
and/or the Town Engineer to determine the extent of clearing and grubbing
and whether or not any existing vegetation within these areas are
to remain. Otherwise, the developer shall clear the entire area within
the limits of:
(1)
The road right-of-way.
(2)
Stream channels and ditches.
(3)
All ledge rock and rock outcroppings shall be removed to below the
elevation of the lowest point of the roadbed and shall be done to
afford proper sight distances, drainage and runoff.
(4)
Easement areas (as determined by the Town Highway Superintendent
and the Town Engineer).
B.
All stumps, roots, walls, structures, abandoned utilities, and debris
shall be excavated and removed from the above areas.
A.
The developer shall complete the shaping of the road right-of-way,
streams and ditches and easement areas to the line and grade as shown
on the approved plans and as otherwise may be directed by the Town
Highway Superintendent and the Town Engineer. In the construction
of the roadway, all topsoil, loam, rocks and organic materials shall
be removed until a satisfactory subbase is established. All fills
shall be made with acceptable material as approved by the Town Highway
Superintendent and the Town Engineer. Such fill shall be made in layers
of not more than eight inches each and properly compacted with a 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 Highway Superintendent and the Town Engineer before the geotextile
and foundation course is laid. No large stones or rock ledges shall
protrude into the foundation course. All slope areas shall be graded
and all loose and exposed stones shall be removed.
C.
Stakes with final line and grade shall be maintained by the developer
at all times to check the foundation course.
A.
The drainage system and/or culverts shall be designed in accordance
with established engineering principles and approved by the Town Highway
Superintendent and the Town Engineer. Plans for any drainage structure
other than pipe culverts, when existing or proposed, shall be submitted
in detail to the Town Highway Superintendent and the Town Engineer
for approval. The minimum grade of any drainage pipe or culvert shall
not be less than 1%. The approved plans shall show invert elevations
of the inlet and outlet of all drainage structures. Any deviation
from the approved plans shall be on approval of the Town Highway Superintendent
and the Town Engineer, in writing. No culvert pipe shall be less than
15 inches in diameter unless by approval of the Town Highway Superintendent
and the Town Engineer. Pipe for culverts may be high-density polyethylene
pipe (HDPE) with a smooth interior or reinforced concrete pipe Class
III, which shall conform to the last ASTM and AASHTO Standards. Pipes
greater than 36 inches in diameter shall be concrete pipes. End sections
shall be placed at all pipe inlet or outlet ends, where appropriate.
Where required, headwalls of concrete or mortared stone masonry shall
be constructed. 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 NYSDOT Item
No. 304.12. It shall be the responsibility of the developer that no
headwalls shall crack or become tipped from settlement. A concrete
mix of 4,000 psi after 28 days shall be used.
B.
The width of the trench in which the pipe (see trench detail in appendix)[1] is laid shall be sufficient to permit thorough compaction
of the backfill around the pipe and a minimum of 24 inches wider than
the outside pipe diameter. A cushion of at least six inches shall
be laid in line with grade prior to laying the pipe. No rock over
three inches in size shall protrude or lie in this cushion. The soil
below the cushion shall be stable enough so that there will be no
settlement of pipe after backfilling the trench.
[1]
Editor's Note: Said detail is included at the end of this chapter.
C.
The pipe shall be laid to true line and grade on the prepared bed
of the trench. Backfilling of the trench shall be done with roadway
foundation material approved by the Town Highway Superintendent and
the Town Engineer. The backfill shall be made in layers of no more
than six inches, which shall be compacted. In no case shall the top
of any drainage pipe be less than 24 inches below the finished grade
of pavement. Alignment of pipes shall be in a straight line between
drainage structures.
D.
All drainage structures (pipes, basins, etc.) shall be of a size
sufficient to carry potential water runoff and stormwater generated
by a twenty-five-year storm for the upstream watershed areas of less
than 200 acres and by a one-hundred-year storm for watershed areas
greater than 200 acres and also that which, in the opinion of the
Town Highway Superintendent and the 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. Sizing of all structures shall comply
with the Town guidelines in effect at the time of construction. Additional
or larger culverts and drainage structures shall be installed and
paid for by the developer if the Town Highway Superintendent and the
Town Engineer so direct. Drainage structures (catch basin detail located
in appendix)[2] shall be backfilled with NYSDOT Item No. 304.12. Backfill
material shall be "chucked" under the piping to ensure all voids are
filled so as to prevent settlement. Backfill material shall be compacted
in six-inch lifts around catch basin structures with a vibratory "jumping
jack" compactor.
[2]
Editor's Note: Said detail is included at the end of this chapter.
E.
With the approval of the Town Highway Superintendent and Town 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. All open drainage lines and swales shall
be protected against erosion by suitable stabilizing materials or
construction.
(1)
The grade of any open ditch shall not exceed 10%. Rip-rap shall be
used on grades greater than 6% and shall consist of rough, unsewn
quarry stones as nearly cubical in form as is practicable, placed
upon a slope not steeper than 1 on 2 and so laid that the weight of
the larger stones is carried by the soil and not the stone adjacent.
(2)
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.
(3)
Whenever a drain pipe enters an open ditch, the bottom and sides
of the ditch shall be rip-rapped for a distance of at least 20 feet
beyond the end of the pipe. The drainage pipe shall terminate with
an end section or at a headwall.
A.
Before fine grading or construction of curbs is started, all storm
sewers and all utilities shall have been installed and all fill and
backfill shall have been thoroughly compacted to the satisfaction
of the Town Highway Superintendent and Town Engineer.
B.
After completion of the rough grade and prior to the laying of the
geotextile and 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.
C.
Any soft, unstable, or unsuitable portions of the subgrade which
develop under proof rolling with a fully loaded tandem dump truck
shall be completely excavated and removed from the right-of-way and
shall be replaced with acceptable granular material and/or geotextile
and the area regraded and compacted as above.
D.
Prior to installation of foundation course, a nonwoven, needle-punched,
geotextile fabric shall be laid upon the subgrade along the entire
length of the proposed roadway. Geotextile fabric shall be overlapped
18 inches minimum at all seams. Geotextile fabric (MIRAFI S1200 or
approved equal) shall meet the following minimum properties, in accordance
with ASTM test methods:

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 Town Highway Superintendent and the Town Engineer, the developer
shall furnish and place a foundation course of New York State Department
of Transportation (NYSDOT) Item No. 304.12 to the depth as called
for in these sections. All materials acceptable for this course shall
be hard, durable and sound and shall be well graded from coarse to
fine, the maximum diameter of the large particles not exceeding two
inches, 25% to 60% by weight, shall pass the one-quarter-inch-square
sieve, 5% to 40% by weight, shall pass the No. 40 mesh sieve, and
not more than 10%, by weight, shall pass the No. 200 sieve. A certified
analysis of granular material shall be filed with the Town Highway
Superintendent and Town Engineer.
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 Town Highway Superintendent and the
Town Engineer may consider necessary for proper compaction. After
compaction, the course shall be true to grade and cross sections,
and depressions shall be eliminated by the use of additional granular
material thoroughly rolled in place. In all cases, the foundation
course must be thoroughly compacted so that it will not weave under
the roller.
C.
Prior to placement of any pavement, all roadways shall be proofed-rolled
with a fully loaded tandem dump truck in the presence of the Town
Highway Superintendent and the Town Engineer, in a manner prescribed
by the Town, and any defective or unacceptable sections shall be reconstructed
as necessary and retested prior to paving operations.
After the foundation course has been inspected and accepted
by the Town Highway Superintendent and the Town Engineer and found
to be at the grade allowing the proper depth of finished pavement,
the following base course shall be laid:
A.
Hot-mix asphalt concrete pavement: material.
(1)

be repaired by replacement of the unstable material or by patching
with a material to produce a tight surface having the same elevation
as the surrounding surface.
(3)
All equipment and the condition of the equipment shall meet the approval
of the Town Highway Superintendent and the Town Engineer.
(4)
In the event that the base course has been subjected to traffic for
an extended period of time, a tack coat or asphalt emulsion at a rate
of 0.05 gallons per square yard shall be applied to the surface in
accordance with the requirements of the current NYSDOT Specifications,
Section 407, prior to the placement of the binder course.
After the binder course has been placed, inspected and approved
by the Town Highway Superintendent and Town Engineer, the following
top course shall be laid:
A.
Hot-mix asphalt concrete pavement: material.
(1)
Finish course shall consist of a hot-mix asphalt concrete, conforming
