The standards and specifications for single-family
residential subdivisions are contained in these regulations. Additional
improvements or improvements meeting more stringent standards and
specifications may be required by the Planning Board for multifamily
dwellings and commercial and industrial subdivisions.
All improvements granted final approval shall
be constructed in each new subdivision in accordance with the standards
and requirements established by the Town Planning Board and in accordance
with the condition of the final approval. The owner may install such
improvements at his own cost and expense or may secure the formation
of a special district to install such improvements pursuant to pertinent
laws of the State of New York.
[Amended 3-2-2006; 2-1-2007; 8-1-2019; 4-7-2022; 4-4-2024]
The following specification is the standard
for the construction of new roads in the Town of Wilton, Saratoga
County, New York. It provides both minimum requirements for materials
and workmanship for roads built on sand or granular subgrades and
new roads constructed on silty or clayey subgrades (A-6 and A-7 soil).
[Note: Reference is made to American Association of State Highway
and Transportation Officials soil classifications A-1 through A-7
as defined in the Asphalt Institute Manual, Series No. 10 (MS-10),
March 1978 Edition.] Unless specifically stated otherwise by Highway
Superintendent, all road work shall conform to the most recent version
of Town road specifications and New York State Department of Transportation's
Standard Specifications.
A. Clearing and grubbing of right-of-way. Sod, topsoil,
organic matter, foreign material and cobbles larger than four inches
shall be removed from the entire right-of-way and shall be disposed
of in an acceptable manner. In cases where the subgrade consists of
A-6 or A-7 soil, the removal of the appropriate amount of this material
shall be accomplished in an acceptable manner prior to grading the
subgrade.
B. Effect of weather conditions on construction. Application
of asphaltic concrete on new roads shall be permitted only during
the time period of April 1 to November 1. The temperature during this
time for construction shall be at least 50° F. Construction shall
not occur during wet weather or during other adverse weather conditions.
Deviation from these conditions shall be permitted only by special
permission from the Town Highway Superintendent.
C. Subgrade. The "subgrade" is defined as the original
soil existing in the right-of-way over which the subbase is to be
placed. "Artificial subgrade" refers to the granular material used
to replace a specified depth of removed poor subgrade material.
(1) Grading and compaction. Grading and compaction of
the subgrade shall commence after completion of the clearing and grubbing
operation and shall be done in compliance with the accompanying drawing
and the approved grade profile prior to the application of the subbase
material. Compaction of the subgrade shall be accomplished by means
of a vibratory eight-to-ten-ton roller as outlined in § 203-3.12
B.2 of the New York State Department of Transportation Standard Specifications.
The method of compaction used shall also comply with the above-referenced
standard.
(2) Testing and inspection of the subgrade. Compaction
of the subgrade shall be achieved to the satisfaction of the Town
Highway Superintendent and Town Engineer. Placement of the subbase
shall not proceed until approval of the subgrade is received from
the Town of Wilton.
D. Subbase. The subbase course shall consist of NYSDOT
Type 2 (Item 667.02 of the New York State Department of Transportation's
Standard Specifications) and of a thickness equal or greater than
that referenced in the Typical Road Section.
(2) Testing and inspection of the subbase. Prior to the
placement of the subbase, the contractor shall have a sample analyzed
that is truly representative of that material to be used for compliance
with the appropriate New York State Department of Transportation standard.
A New York State approved laboratory for sieve analysis shall be used.
The results of the sample tested shall be submitted for the Town's
approval. Town approval, in writing, shall be obtained before the
commencement of any work. Additional testing may be required at the
discretion of the Town of Wilton.
(3) Construction. The maximum thickness of lifts permitted
for the subbase shall be six inches. Compaction of the subbase shall
be accomplished by means of an eight-to-ten-ton roller or other compacting
device defined in § 203-3.12 of the New York State Department
of Transportation Standard Specifications and shall be graded in accordance
with the accompanying drawing. Any imperfections, irregularities or other damage in the
subbase shall be repaired prior to the installation of the base course.
E. Binder course.
(1) The binder course shall consist of a thickness equal
or greater than that referenced in the Typical Road Section, after compaction, of Type 3 asphalt concrete (New York
State Department of Transportation Standard Specifications Equivalent)
binder material.
(2) Application of the binder course shall be in conformance
with § 401-3 of the New York State Department of Transportation
Standard Specifications and shall be graded as shown on the accompanying
drawing and the approved grade profile.
F. Intermediate and final top courses.
(1) The intermediate and final top courses shall consist
of a thickness equal or greater than that referenced in the Typical
Road Section, after compaction, of Type 6F asphalt concrete (New York
State Department of Transportation's Standard Specifications Equivalent)
top material.
(2) Application of the intermediate and final top courses
shall be in conformance with § 401-3 of the New York State
Department of Transportation's Standard Specifications and shall be
graded as shown on the accompanying drawing and the approved grade profile.
(3) The construction of the final top course shall be deferred until
90% or more of the building lots fronting on the section of road in
a particular phase have received certificates of occupancy and before
the last building lot certificate of occupancy or by order of the
Town Highway Superintendent and Town Engineer.
(4) All pavement penetrations, except valves and manhole
covers, shall be set flush with the intermediate paving course elevation;
valves and manhole covers shall be set 1/4 inch below the intermediate
course elevation. Metal risers shall be installed just prior to final
top course paving to keep the pavement penetrations flush with the
top course elevation, except valves and manhole covers shall be set
1/4 inch below the top course elevation.
G. Poor subgrade; minimum requirements.
(1) A "poor subgrade" is defined as that which consists
of silty or clayey material and designated A-6 or A-7 under the American
Association of State Highway and Transportation Officials soil classification
system.
(2) When a poor subgrade exists, an artificial subgrade,
as previously defined, shall be substituted for a portion of the subgrade
as shown on the drawing. The artificial subgrade shall consist of
granular material (sand) and shall be approved for use by the Town
Highway Superintendent prior to installation. The compacted depth
of the artificial subgrade shall be 12 inches.
(3) Additional requirements shall be imposed if deemed necessary. Core
samples are to be taken as directed by Highway Superintendent.
H. Industrial and commercial roads. Roads intended primarily
for industrial or commercial uses or other surfaces subjected to excessive
wheel loadings may require special design. These situations shall
be evaluated on an individual basis and designed as per Town Engineer
and Highway Superintendent's direction.
I. Drainage facilities.
(1) Prior to the construction of drainage facilities,
the plans and specifications shall be approved by the Town Highway
Superintendent and the Town Engineer, in writing. The basis for the
design of drainage facilities shall be accomplished by means of an
acceptable method for calculating runoff, such as the Rational Method
or Soil Conservation Service Technical Release No. 55. Complete calculations
for determining runoff quantities shall accompany all submittals for
Town approval.
(2) Catch basins shall be a minimum four feet inside diameter.
Drop inlets may be used in lieu of catch basins for the purpose of
collecting surface water discharge to a catch basin. Drop inlets shall
be at least 2 1/2 feet square. The height shall be ample to provide
minimum cover over pipe as required. See Catch Basin Detail for both
catch basin and drop inlet design.
(3) Unusual conditions.
(a)
Where unusual conditions exist, such as the
need for groundwater recharge to replenish water wells, flat topography,
excessively high or low groundwater table, etc., a special design
for stormwater systems shall be required.
(b)
In areas where topography limits stormwater
system design to on-site disposal, it is preferred that retention
areas be used, if conditions warrant it, in conjunction with an underdrain
system. Dry wells may be incorporated in the overall design on certain
cases.
(4) Drainage easements shall be created a minimum of 25
feet from the top of drainage swales and basins in order to ensure
that the Town has adequate area for any future maintenance.
J. Additional requirements.
(1) In certain cases, guiderails may be required. This
requirement shall be discussed with the owner during the plan review
process, if required. All guiderails shall be box beam per NYSDOT
Specifications.
(2) Road elevation shall ensure the construction of driveways
with a maximum slope of 5% from pavement edge to the road right-of-way
line.
(3) The radii at all intersection shall be 35 feet for
subbase, base, intermediate and top courses.
(4) All new roads shall receive a graded layer of suitable
topsoil material from the edge of the pavement to the right-of-way
extremity. Mulching and seeding of this area shall occur as soon as
practical. The road shall be acceptable to the Town only upon the
appearance of a dense stand of grass in nonblacktopped areas.
(5) All catch basins, drop inlets and piping shall be
free of sediment, silt and debris when accepted by the Town of Wilton.
(6) Areas containing erosion or eroded soil or areas not
containing a dense stand of grass contained within the road shall
constitute grounds for denial of acceptance.
(7) Prior to the issuance of any certificates of occupancy
or the acceptance of the road, property pins shall be placed on the
front corners of the property designating the line between the landowner's
property and the Town right-of-way.
(8) All stumps, grubbings, logs, and limbs generated from
subdivision projects shall be hauled off-site and disposed of properly.
Chipping/tub grinding of this material on-site will be allowed in
lieu of off-site disposal, if approved by the Planning Board. These
grindings shall not be disposed of in any defined open space areas.
[Amended 7-2-2002; 3-6-2003]
A. The Town Board may require the establishment of a letter of credit
(bond or other acceptable financial securities) which shall cover
the cost of all improvements in the public right-of-way, with the
exception of water distribution and sewage collection systems and
all other items considered to be Wilton Water and Sewer Authority
improvements. A detailed written estimate of all costs shall be provided
to the Town. Costs shall reflect current values for the work and materials
involved and shall be representative of actual cost to the Town of
Wilton to execute the work should the contractor or owner not complete
the project. Cost estimates shall be reviewed by the Town Highway
Superintendent and the Town Engineer.
[Amended 8-1-2019]
B. The letter of credit shall include assurance of reimbursement
of maintenance costs to the Town if needed prior to the expiration
date of the letter of credit and an inflation factor if deemed appropriate.
C. The written approval of the Town Engineer and Highway
Superintendent of the plans and specifications for the new road and
drainage system shall precede letter of credit acceptance.
D. The final amount of the letter of credit shall require
the approval of the Town Board.
E. The form of the letter of credit shall be acceptable
to the Town.
[Amended 7-2-2002; 3-6-2003]
A. Various items of construction may be inspected and
approved upon their completion and the amount of the letter of credit
may be reduced, provided that it does not become less 20% of the original
value of the letter of credit.
B. The creation of a letter of credit (or continuance of the initial
letter of credit) in an amount equal to 20% of the cost of the road
construction shall be in effect until one year after the granting
of final acceptance, and subsequently reduced to 10% for the second
year and until completed. The 20% to 10%, two-year letter of credit
shall be a single document accepted by the Town prior to the acceptance
of the road.
[Amended 8-1-2019]
C. When the top course is being deferred, a separate
letter of credit for the full value of cleaning the binder course,
tack coating and paving of the top course may be required by the Town.
After the top course is installed and accepted, the twenty-percent
to ten-percent, two-year letter of credit may also be required for
this top course work.
The Town Board may require that the construction
of all new roads in the Town of Wilton shall be certified by a New
York State licensed professional engineer. This certification shall
consist of a statement by the owner's engineer, seal affixed, certifying
he has inspected the installation of the improvements within the subdivision
and certifies that they have been installed in accordance with the
plans which received final approval by the Planning Board.
Owners of parcels deeded to the Town after the
taxable status date (March 1) shall have to pay taxes for the entire
following year.
