This article shall be known and may be cited
as the "Streets or Highways Resolution of the Town of Guilderland."
The purpose of this article is to regulate the design and construction of streets, thoroughfares or highways and all utilities therein in the Town of Guilderland, Albany County, New York. This article is to be used in conjunction with, and is complementary to, Chapter 247, Subdivision of Land, and Chapter 280, Zoning.
A.
Wherever used in this article, the word "street" and/or
"right-of-way" shall also mean a thoroughfare, highway or road.
B.
Wherever used in this article, words in the singular
number include the plural, and words in the plural number include
the singular.
C.
The word "shall" is mandatory and not directory. Words
used in the present tense include the future.
All applications for the dedication of streets
and rights-of-way to the Town of Guilderland shall be accompanied
by a warranty deed or, if a warranty deed is not possible, by a quitclaim
deed conveying said street and rights-of-way to the Town with all
releases from mortgages or other claimants, together with a proper
title search covering at least 30 years to the time application is
made, and also a tax search. Such application shall also be accompanied
by a plan or plans which shall:
A.
Be at a scale of one inch equals 50 feet. The use
of any other scale must have had prior approval of the Town Planning
Board.
B.
Show contours based on United States Geological Survey
(USGS) datum and at an interval not greater than two feet. Interpolation
of contours from other mapping shall not be accepted.
C.
Show a minimum of two benchmarks based on USGS datum.
D.
Show a location plan, at a minimum scale of one inch
equals 2,000 feet, giving the location of the plot with relation to
established streets.
E.
Show, on a separate plan of the same scale as the subdivision plan, all drainage areas tributary to the development; show drainage area limits tributary to each catch basin or inlet with a tabulation of runoff to each structure and the total to each outfall; show detention area details with storage volume calculations including maximum detention times to drain completely and all based on the Stormwater Management Plan as defined in Chapter 247, Subdivision of Land. Calculation of runoff shall be based on a method in general use for the area involved and approved by the Town Engineer. The method used shall be approved by the Town Engineer, or designated engineer, and shall be recognized as producing a problem-free storm drainage system. Calculations for all stormwater structures shall be based on rainfall intensities resulting from a storm of a ten-year return. The designer shall examine and report on the routing and effects on the area and system for the one-hundred-year storm event. The storm drainage plans, calculations and narratives shall be submitted to the Town Engineer and/or the Town-designated engineer for review.

C.
Public utilities shall be installed without expense
to the Town and under the supervision of the Town Superintendent of
Highways and the Superintendent of Water and Wastewater. The installation
of said utilities shall be accomplished without cutting of pavement
within the Town highway rights-of-way, and a permit shall be obtained
from the Highway Superintendent for the work to be done. Power, telephone
and gas, where installed under the pavement, shall be placed in a
protective sleeve. Unless a specific permit is issued by the Highway
Superintendent, no pavement shall be broken and all facilities shall
be jacked, bored or driven under said pavement only under his direction.
The arrangement of streets or highways hereinafter
laid out shall, wherever possible, provide for the continuation of
the principal streets existing in the adjoining subdivisions, or of
their proper projection when the adjoining property is not subdivided,
and shall be of a width as great as that of such existing streets,
but in no case have a right-of-way width less than 60 feet.
The minimum width of street or highway rights-of-way
hereinafter laid out shall be 60 feet. These widths shall be measured
from right-of-way line to right-of-way line. Said width shall be measured
normal to the lines on tangents and on the radial lines on curves.
There shall be no reserve strips controlling
access to streets except where control of such strips is definitely
placed in the Town under the offer to dedicate.
Property lines at all street intersections shall be rounded sufficiently to allow a minimum radius on the property line of 25 feet. (Also see Chapter 247, Subdivision of Land.)
A proposed design for each highway intersection
shown on the approved subdivision plan shall be submitted to the Town
for approval, and such approval shall have been granted prior to the
construction of any of the proposed highways and prior to the final
approval of the highway profiles by the Town. Each intersection shall
be shown on a separate sheet (normally 8 1/2 inches by 11 inches
or nine inches by 12 inches) and shall be drawn to a scale of one
inch equals 30 feet. The intersection shall be designed to shed all
surface water to inlet structures on the existing, or proposed, highway
drainage system, and such structures shall generally be placed at
the P.C. or P.T. of curves. The design drawings shall show the edges
of the pavements, with intersecting edges of pavements being connected
by a curve having a minimum radius of 40 feet. The drawings shall
also show right-of-way lines, the center lines of pavements, proposed
elevations along the edges of pavements, proposed elevations along
the center lines of pavements and proposed elevations along the right-of-way
lines. The design drawings shall also show the location of all storm
drain lines, structures on the storm drain lines with elevations of
grates or covers, and curve data for all horizontal curves shown on
the intersection design.
All pipe and necessary appurtenances for the
proper and satisfactory collection and disposal of subsurface, or
underground, water from the rights-of-way of the proposed highways
shown on the approved subdivision plan, in order to establish a satisfactory
roadbed for such highways, shall be supplied and installed by the
owner of the subdivision in accordance with the pertinent specifications
of the Town. The necessity for draining subsurface water from the
right-of-way of a proposed highway, the locations where such drainage
is required, and the extent of piping necessary to effect such drainage
shall be determinations of the Superintendent of Highways. These determinations
by the Superintendent of Highways may precede the construction of
the proposed highway or may occur during construction as underground
water conditions become evident. The Town Superintendent of Highways
will notify the owner of such determinations as soon as possible after
such determinations are made. Type of pipe, diameter and gauge of
pipe, pipeline gradients, method of pipe placement and all materials
required for the installation of such drainage shall conform to the
requirements and specifications of the Town.
Streets designed to have one end permanently closed shall be provided at the closed end with a turnaround roadway having a minimum radius for the outside property line of at least 80 feet. Full pavement area shall extend to within 15 feet of the outside right-of-way line. (See Chapter 247, Subdivision of Land.)
Street grades shall not exceed 8% nor be less
than 0.8%. Particular attention shall be given to street design at
intersections. Approach grades shall not exceed 3% within 120 feet
of the street right-of-way line intersected and shall not exceed 1
1/2% within 40 feet of the right-of-way line intersected. Combinations
of grades over 6% with curves of minimum radius shall not be used.
Where the algebraic difference in street grades exceeds 2%, the grades
shall be connected by a vertical curve to produce a safe transition.
Street intersections shall be at 90º within
100 feet of the intersected right-of-way line. Street tangents with
a deflection angle greater than 5º shall be connected by a minimum
radius of curve of 250 feet, measured to the inside right-of-way line.
Street layouts for proposed higher density development than standard
R-15 or R-20, that is for clustered or townhouse development, may
be approved at less radius of curve, but traffic safety provisions
and necessary street signage must be as recommended by a qualified
traffic safety engineer employed and paid by the owner/developer at
no cost to the Town.
Intersecting streets shall be so planned that blocks between street lines shall be not more than 1,200 feet in length, and any variance from this length because of an unusual topographic condition or more efficient land use shall have prior approval of the Planning Board. (Also see Chapter 247, Subdivision of Land.)
The planting of street trees within the right-of-way
is prohibited; however, shrubs with a mature height not greater than
18 inches, combined with grassed areas, shall be planted and maintained
until street dedication by the landowner/developer. These areas shall
include the center mall areas of divided streets and turnarounds.
The plan for this planting shall have prior approval of the Highway
Superintendent.
A.
Sufficient monuments shall be placed to properly reproduce
each and every street laid out. Street monuments shall be placed in
the immediate vicinity of all intersections and at intervals not exceeding
500 feet on tangent lengths of over 1,000 feet. Where monuments are
placed between intersections, they shall be placed in pairs, one on
each side of the street, and shall be accurately correlated to one
another by bearing (angle) and distance.
B.
Monuments shall be of concrete that is 4,000 pounds
per square inch, reinforced with four No. 3 deformed reinforcing and
four inches square and four feet in length. A galvanized or stainless
steel pin 3/8 inch in diameter shall be anchored on center and flush
with the top of the monument. The top of the monument shall be set
flush with the finished grade.
A.
In general, storm sewers will be required and shall
be designed to carry the flow tributary. The distance which water
shall be allowed to run in open ditches will be determined in each
individual case depending upon the various factors involved. In areas
of minimum grade, this distance shall not exceed 750 feet, and in
areas of maximum grade, this distance shall not exceed 250 feet.
B.
Storm sewers, where installed, shall be of reinforced
concrete pipe or corrugated metal pipe (galvanized steel), fully coated,
with paved invert, and, generally, shall be laid on grades to produce
a velocity of not less than three feet per second nor more than eight
feet per second when flowing full. Under special conditions involving
circumstances such as level terrain and shallow surface water outlet,
permission to install storm sewers at grades producing velocities
of not less than two feet per second when flowing full may be granted
by the Town Superintendent of Highways. Storm sewer design shall be
on the basis of local ten-year storm frequency studies and shall be
such that a minimum of four feet zero inches is maintained from invert
of pipe to finish ground surface directly above.
C.
Reinforced concrete pipe shall conform to ASTM Specifications
Class III for Reinforced Concrete Pipe. In certain locations, the
Highway Superintendent may require the use of ASTM designation C-76
Class IV or Class V.
D.
Corrugated galvanized steel pipe, multiplate pipe
and pipe arches shall be fully coated with a paved invert and shall
not be less than the gauge recommended by the American Association
of State Highway Officials but not less than 16 gauge. Lengths of
C.M.P. shall be joined with corrugated collars. All pipe ends shall
be corrugated. All joints are to be encased in graded filter gravel,
15 inches either side of the joint to a minimum depth of 12 inches
above and six inches below the pipe. Local soil conditions may increase
these requirements. All C.M.P. 48 inches in diameter and larger shall
be strutted. Struts shall be removed after total compaction of the
backfill material in six-inch lifts has been completed.
E.
The use of helically-formed corrugated steel pipe
shall require reformed annular ends to receive standard connectors.
The use of dimpled connectors is prohibited.
F.
All storm sewers shall be constructed accurately to
line and grade, properly bedded, and shall be so constructed that
all joints are watertight.
G.
Typical installation details are shown on the attached
drawing, Town of Guilderland - Construction Detail Sheet.[1] The design of stormwater inlet basins and manholes shall
be acceptable to the Town Superintendent of Highways and shall be
in accordance with current standard modern practice. In no case will
the use of concrete manhole block less than eight inches in width
be permitted.

Highways and/or the Town-designated engineer prior to installation.
Pipe connections shall be completely sealed with hydraulic mortar
for the full thickness of the structure wall.
I.
The minimum inside diameter of pipe for storm sewer
use shall be 12 inches. The minimum steel thickness for corrugated
steel pipe shall be 16-gauge. Shallower or deeper installations than
standard or in particularly corrosive soil or flow conditions shall
require the use of a heavier gauge, subject to the approval of the
Highway Superintendent.
J.
All catch basin and junction structures over four
feet in depth shall have substantial, noncorroding steps for safe
access, and structures over eight feet in depth shall have an offset
cone section. All structures less than eight feet in depth shall be
equipped with a reinforced concrete flat top designed for a minimum
H-20 highway load and set so the manhole opening is over the outlet
pipe. Frames and grates shall be Campbell Foundry Pattern No. 2253.
Solid covers where required on certain structures shall be Campbell
Pattern No. 1203. Inlet basin covers shall be set level and flush
with finished gutter paving.
L.
The developer or owner laying out the streets or highways
for acceptance by the Town shall obtain all necessary easements and/or
rights-of-way to take care of all surface and ground water caused
by reason of the development of said street or highway and by reason
of the installation of culverts or surface drains or underdrains.
No street or highway will be accepted by the Town of Guilderland nor
approved by the Town Superintendent of Highways and Superintendent
of Water and Wastewater before such necessary easements or rights-of-way
have been obtained and passed upon by the Attorney for the Town of
Guilderland. The width of easement or right-of-way shall be 30 feet
minimum for installation depths of six feet or less. At the discretion
of the Town Superintendent of Highways and/or the Superintendent of
Water and Wastewater, greater installation depths may require wider
easements or rights-of-way depending upon particular circumstances.
Prior to being offered for dedication to the
Town, all streets shall be completely graded, within the limits of
