It is the purpose of these specifications to establish minimum
acceptable methods of street construction, including widths and development
of right-of-way, paved roadway, storm drainage and other utilities
in the Village of New Hempstead. Dedication of the right-of-way will
not be acceptable until the Village Engineer shall have certified
to the Village Board that the development of the street has been completed
in accordance with the approved plans and the specifications which
follow.
A plan of the proposed street shall be prepared by a qualified
engineer properly licensed by the State of New York or a land surveyor
possessing a proper exemption certificate issued by the State of New
York Education Department. The plan shall clearly define the limits
of the proposed right-of-way and shall include the location, width,
profile 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 Town Superintendent
of Highways and/or to the County Superintendent of Highways when any
street drains toward or connects to a county highway or town road
and to the Village Planning Board for review and approval under the
applicable Subdivision Regulations of the Village. Such plans so submitted shall not be altered or amended
after having been approved by the Planning Board, except after amended
plans have been resubmitted and approved as above. However, the developer
shall, at his own expense, provide additional storm drainage facilities
as may be ordered by the Town Superintendent of Highways, the County
Superintendent of Highways or the Village Engineer where such additional
structures or facilities are necessary to assure the durability of
pavement and future maintenance of the right-of-way.
Excavation and backfilling for underground utility pipes and
cables shall be done in strict conformance with the requirements outlined
above for storm drain construction. All utilities shall be placed
prior to the paving of new roadways.
If there are no sidewalks, shoulders and slopes to complete
the balance of the right-of-way shall be at least 10 feet wide and
shall be graded to meet the finished elevation of curbs or gutters
on a slope of 1/2 inch per foot for a distance of five feet from the
edge of the curb or gutter and thence on a slope of not more than
one vertical to two horizontal to the limits of the right-of-way,
both in cut and fill. Exceptions to these requirements, where rock
or other conditions exist, may be approved by the Village Engineer.
On any fill section where the elevation of the shoulder is five feet
or more above that of the toe of the slope, the developer shall provide
guide railing on the shoulder as approved by the Village Engineer.
Shoulders and slopes shall be dressed, topsoiled and seeded by the
developer.
After the wearing course of pavement has been placed, monuments
shall be placed in the road center line at each point of curvature,
point of intersection, point of tangency and at center-line intersections
of intersecting streets, Monuments shall be railroad spikes or similar
iron devices at least six inches long with one-half-inch minimum square
shanks and one-inch minimum diameter heads. Reference ties from at
least three permanent locations (house corners, preferably) shall
be recorded. The surveyor shall prepare a certified map showing the
locations of the monuments and reference ties and file two copies
with the Village Engineer, who shall submit the same to the Planning
Board for its determination as to sufficiency by holding a hearing.
If the Planning Board finds this map sufficient, it shall then be
filed with the Village Clerk. These monuments are in addition to the
monuments required on the right-of-way line by the Planning Board
as part of the subdivision approval.
Upon completion of the public improvements, the surveyor shall
prepare a survey map of the street(s), showing as-built elevations
of the street center line; top-of-grate and invert elevations of all
storm drains and sanitary sewers; sizes, locations and types of pipes;
locations and sizes of any underdrains; and locations and grades of
open channels. The surveyor shall obtain record information on all
underground utilities, including electricity, telephone, gas, water,
sewer and cable television connections, and show the locations of
these utilities with due notice concerning those which are not the
result of the surveyor's own field locations. Two sets of these
drawings shall be filed with the Village Planning Board, which shall
hold a hearing to determine their sufficiency. If the Planning Board
finds them sufficient, they shall be filed with the Village Clerk.
Twenty-four hours' minimum notice shall be given to the
Village Engineer before any work covered under these specifications
commences. Where grade sheets are required, one copy shall be delivered
to the Village Engineer 24 hours before work commences.
The following is a list of requirements to be imposed by the
Village prior to a developer offering any road for dedication to the
Village:
A. A licensed professional engineer must prepare the infiltration/exfiltration
tests and results submitted to both the Rockland County Sewer District
No. 1 and the Town of Ramapo Highway Department and submit proof of
compliance to the Village.
B. A letter from the Town of Ramapo should be required to be submitted
to the Village. Said letter should indicate that the town has inspected
the sewer within the last 60 days and finds it acceptable as to design
standards.
C. An inspection should be made, within the last 60 days, of the storm
drainage structures in order to ascertain that each catch basin has
been properly constructed, that the grates have been properly set
on the top of the structure(s) and that the catch basin(s) is (are)
clean and not silted up.
D. Any headwalls that have been constructed as part of the storm drainage
system must also be inspected, and the details required for their
construction must be in place and acceptable.
E. Concrete curbs and sidewalks should be inspected by the Village Engineer
at a minimum of 60 days prior, and a letter is required from said
Engineer, indicating that all of the curbs are in place and have not
buckled nor spalled.
F. Letters should be required from all of the utility companies (the
cable television, Orange and Rockland utilities, Spring Valley Water
Company and telephone companies) indicating that all underground utilities
required for the road and subdivision have been placed and tested
and are in good operating condition, thereby not requiring digging
up of the street for repair(s) for a period of five years, other than
for emergencies.
G. As part of the installation of curbs and sidewalks, a testing lab
report is required for each one of the items that is placed to indicate
a seven-day and twenty-seven-day design strength of the concrete (for
every 25 cubic feet of concrete).
H. The asphalt pavement must be tested and reported as to compliance
with the design specifications for the road(s). The asphalt must also
be tested for each 40 tons placed. In lieu of this testing procedure,
the Village should reserve the right to have the contractor, at selected
locations, take samples of the placed material(s) and have them tested.
This procedure would only apply for installations that have not been
inspected by the Village and that cannot comply with the testing requirements
at the time of placement of the material.
I. The contractor or developer should provide a list to the Village
of all subcontractors that have worked on the project, together with
a release signed by each of the subcontractors provided to assure
that all work has been paid for and no liens are placed on the particular
project.
