line of a roadway at all road intersections, angle points, points
of curve, subdivision corners, easements and other locations as directed
by the Highway Superintendent or the Town Engineer.
B.
Monuments shall be cut granite, free from imperfections, or concrete, and as shown on Figure VII-5. Iron pipes, unless embedded in concrete, shall not be considered permanent monuments for the purpose of this specification.
C.
Monuments shall not be set until the roadway has been
completed, nor shall they be set while frost is in the ground. They
shall be set and tamped to prevent settlement, shifting or movement.
Monuments shall be set so that they cannot be easily removed, if necessary
by encasing the lower half in a concrete anchor (similar to a fence
or sign post).
D.
The developer's licensed land surveyor shall certify
that the location of all monuments is accurate, before acceptance
of the highway by the Town Board, and all monument locations shall
be shown on the as-built drawings (plans).
A.
The type and need for guiderail installation shall
be approved by the Highway Superintendent and the Town Engineer. All
guiderail installations shall be designed in accordance with Guiderail
II, or latest revision, published by the New York State Department
of Transportation Traffic Safety Division.
B.
The primary warrants to determine the need for guiderail
are:
(1)
Height of drop-off (measured from the break
of shoulder slope to the toe of slope) compared to the rate of embankment
slope. Guiderail is not warranted unless the geometry of the features
involved exceed the criteria below:
|
Slope (H:V)
|
Embankment Height
| |
|---|---|---|
|
2 to 1
|
6 feet
| |
|
3 to 1 or flatter
|
Guiderail not required
|
|
It is also assumed in the above geometrical
consideration that the toe of slope conditions are such that no abrupt
dropoffs or adverse slopes forming "V" ditches will be encountered.
|
(2)
Guiderails shall be installed to protect motorists
from fixed objects and roadside hazards as shown on the following
list:
|
Culvert headwalls.
| |
|
Along bodies of water over two feet deep.
| |
|
Rock cuts and rock outcrops.
| |
|
Retaining walls.
| |
|
Any other immovable object as determined by
the Highway Superintendent.
|
C.
Guiderail installation shall be in accordance with
Sections 710-20, Corrugated Beam Guide Railing, and 710-21 Box Beam
Guide Railing, of the current Standard Specifications of the New York
Department of Transportation (see Figures VII-6 and 7).
A.
All signs, signals, markings and other control devices
for maintenance and protection of traffic and for naming roads shall
conform to the requirements of the New York State Manual of Uniform
Traffic Control Devices.
B.
The developer shall install a stop sign at the intersection of a new road with an existing Town, county or state road and at intersections within the subdivision itself as determined by the Highway Superintendent or the Town Engineer. The developer shall furnish and install a four-way road name sign at every road intersection made by the roads he constructs. See Figure VII-8. The developer may also be required to install other signs, such as W7-4 Children at Play, as determined by the Highway Superintendent or the Town Engineer.
Roof, cellar, trench, curtain, footing or any
other house drain or septic system drain shall in no case be allowed
to flow onto the highway right-of-way. With the approval of the Highway
Superintendent and the Town Engineer, in writing, these drains may
be piped to the roadway and they shall be connected to a catch basin
or to the top of a pipe only. Such drains must be installed prior
to the start of the application of the roadway foundation course.
B.
Design.
(1)
Driveways shall be designed similar to a road intersection. A driveway center line shall be offset from a road intersection center line a minimum of 125 feet. Driveways entering onto a minor local road may be no closer than 45 feet to the stop sign cross bar at an intersection. Driveways shall have adequate sight distance (see § A197-27.).
[Amended 11-14-2002 by L.L. No. 5-2002]
(2)

profile of the existing pavement. Driveway grades shall not exceed
a gradient of 4% within 30 feet of the roadway, then 15% overall,
then 4% within 30 feet of the dwelling. Changes in driveway grades
beyond the highway, street right-of-way, or structure shall not exceed
8% per 10 feet, and the maximum grade shall not exceed 15%. Where
elevations are sought, the developer shall submit driveway profiles,
grading plan and cross sections to permit a technical evaluation of
the proposal by the Building Inspector and the Town Engineer.
[Amended 10-28-2010 by L.L. No. 6-2010]

Driveways shall be able to support a thirty-ton,
three-axle apparatus.
