It is the purpose of these specifications to
establish minimum acceptable standards of street construction for
subdivisions or other new public roads to be constructed in the Town
of Wallkill, including, but not limited to, width, design, drainage,
the construction of base and pavement, curbs and sidewalks, monuments
and signs. Dedication of the right-of-way will not be accepted until
the Town Engineer or the Commissioner of Public Works shall have advised
the Town Board, in writing, that the construction of the street or
streets has been completed in accordance with the approved plans and
the specifications which follow, and recommended acceptance of dedication.
In the written certification, as required above,
the Town Engineer and/or the Commissioner of Public Works shall state
clearly that he or his authorized representative has inspected all
phases of the street construction and that all work has been completed
in accordance with the approved plans and these specifications.
A plan of the proposed street shall be prepared
by a qualified engineer properly licensed by the State of New York.
The plan shall clearly define the limits of the proposed right-of-way
and shall include the location, widths, profiles and grades of proposed
roadways, storm drainage, including culverts and other drainage structures,
and the location of easements and utilities. The plan shall be submitted
to the Commissioner of Public Works and the Town Engineer, and then
to the County Superintendent of Highways when any street drains toward
or may otherwise affect a county highway, and then shall be returned
to the Town Planning Board for review and approval under the applicable
subdivision regulations of the town. Such plans so submitted shall
not be altered or amended after having been approved by the Planning
Board, unless amended plans are resubmitted and approved as above.
However, the developer shall, at his own expense, provide additional
storm drainage facilities as may be ordered by the Commissioner of
Public Works if, during the progress of the work, in the opinion of
the Commissioner of Public Works, the Town Engineer and/or the County
Superintendent of Highways, such additional structures or facilities
are necessary to assure the durability of the pavement, the future
maintenance of the right-of-way or the welfare or safety of the public,
except that the Town Planning Board may vary the requirements of such
order where there are practical difficulties or unnecessary hardships
in the way of carrying out the strict 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
has not been started within two years from the date of final approval
by the Town Planning Board, plans shall be resubmitted and approved
as above.
[Amended 3-23-2006 by L.L. No. 3-2006]
The owner/developer is responsible for the payment of all inspection and as-built drawing fees for work required in §
249-42 C(2). Initially, an inspection fee of a percentage to be set by resolution of the Town Board, of the amount of the construction costs shall be paid to the town prior to the time that the Chairman of the Planning Board signs the final plat and the start of any site improvement work. The inspection fee will be held in escrow by the town (project inspection escrow fund) and will be used to pay any and all town engineering, legal and staff expenses associated with the inspection, as-built drawing preparation and dedication of the improvements. If during the construction of the improvements the project inspection escrow fund is reduced to a level that the Commissioner of Public Works or the Town Engineer deems is insufficient to complete the required inspections, the owner/developer shall, within 30 days notification by the Commissioner of Public Works, furnish such additional inspection fees to the town. If said additional inspection fees are not furnished to the town within said thirty-day period, the owner/developer must cease any and all construction of site improvements until the additional inspection fees are paid. The project inspection escrow fund shall be held in an interest bearing account, and any balance of the account, including interest, shall be returned to the owner/developer after completion and dedication of the improvements.
Figures 1, 2, 3, 4 and 5 show cross sections of each of the four classifications
of subdivision streets. These give the required design, dimensions
and construction details which are applicable to a particular classification.
Following is a comparative summary sheet which lists the major items
of construction for all types of streets and may be useful as a checklist
of requirements. Thereafter are set forth the general and more detailed
specifications for design and construction applicable to all streets.
The developer shall design and construct streets which shall conform
to both the specific and the general specifications.
The developer shall so design, lay out and construct
all driveways both within and without the limits of the right-of-way
such that the latest models of modern cars may enter and leave the
right-of-way without difficulty.
[Amended 5-26-2016 by L.L. No. 11-2016]
In a district where minimum allowable lot sizes
are 15,000 square feet or less, or elsewhere as determined necessary
by the Town Planning Board, the developer shall construct four-inch-thick
reinforced portland cement concrete sidewalks on both sides of streets,
as shown on Figures 1, 2 and 3. Concrete shall be of a mix of 4,000 pounds per square inch (psi) (at 28 days), air-entrained with Durex or equal, one course, properly screened and finished to true grade, and shall be cured, all to the satisfaction of the Commissioner of Public Works. Sidewalks shall also comply with the requirements of the Americans with Disabilities Act (ADA) and American National Standards Institute (ANSI). Refer to §
82-15; D or the Town Building Code.
Side streets shall be constructed such that
they are perpendicular at their intersections with through streets.
Curb radii of 35 feet shall be utilized at intersections, and approach
grades shall be in accordance with Figure 13. When a new street intersects
with an existing narrow road, the design shall be in accordance with
Figure 12.
Where surface water must be lead through other
than right-of-way gutters and storm drains or existing stream channels,
drainage easements having a minimum width of 30 feet and a temporary
width of 50 feet for working access shall be provided in the approved
plans. A greater width shall be provided where called for by other
provisions of these specifications or where necessary to conduct future
maintenance.
Wherever a temporary or permanent dead end is
allowed on a subdivision street, a turnaround shall be constructed.
This turnaround shall take the form of a tee or a circle as required
by the Town Planning Board and shall be constructed as shown on Figures
16 and 17. The temporary type of construction shall be used only
under special conditions when authorized by the Town Planning Board
because of the foreseeable future extension of the street. The circular-shaped
turnaround shall be completely paved with no center island.
Streets shall be so designed that finished tangent
grades will not be less than 1% nor more than 10%. Every change in
grade shall be effected with a vertical curve of sufficient length
to ensure adequate stopping sight distance and to provide for smooth
transition. These vertical curves shall be designed in accordance
with New York State standards for speeds of 30 miles per hour unless
the street is to be posted for a speed limit in excess of the current
town-wide limit.
The final decision as to the interpretation
of any part of these street specifications shall rest with the Commissioner
of Public Works. He shall have the authority to modify the requirements
of these specifications when, in his opinion, conditions make it impracticable
to follow the strict letter of these specifications or when conditions
make it unnecessary to do so.
