shall meet those set forth for Item 304, Subbase Course, in the New
York State Department of Transportation "Standard Specifications"
of latest issue.
(3) Surfacing shall consist of a double layer of asphalt
concrete; the lower layer shall be four-inch-thick Type 3 binder course;
the upper layer shall be one-and-one-half-inch-thick Type 7 top course;
the asphalt surface shall be 24 feet in width.
(4) Where the proposed subdivision lies entirely along
a road which is maintained by a public agency, road surfacing shall
be omitted. All other sections shall apply as to their effect on an
existing road.
D. The subdivider shall incorporate concrete rolled gutters
along both sides of the new roadway. The gutter shall have a minimum
thickness of six inches and a width of three feet. (See Concrete Curb
Section Illustration No. 1-A for details.)

(2) All curb sections, plans and profiles shall be submitted
for approval by the Village of Springville.
E. Sidewalks will be required by the Planning Board and
shall be not less than four inches thick except at driveways, where
the thickness shall be six inches. Concrete design mix shall be as
described for concrete gutter and shall contain reinforcing. The reinforcing
shall be either six inches by six inches by ten-gauge welded wire
mesh or fibrous reinforcement acceptable to the Village of Springville.
Installation and construction techniques shall follow guidelines set
in the New York State Department of Transportation "Standard Specifications"
of latest issue.
F. Other items not included in these specifications shall
be approved by the engineer prior to design completion or start of
construction.
G. Underground utilities.
(1) The standard location of underground utilities shall
be as follows:
(a)
Sanitary sewers, north or east side.
(b)
Gas mains, south or west side.
(c)
Water mains, south or west side.
(d)
Storm sewers, north or east side.
(e)
Other, by village approval.
(2) No utility shall be placed under the roadbed, except
for crossings, unless all service lines for each lot are installed
as part of initial utility construction. Water main service lines
shall end with the curb box at the property line. Sanitary sewer laterals
shall end at the right-of-way line and shall be marked using pressure-treated
two-by-fours that reach from the lateral vertically to a point two
feet above finish grade.
H. All roads, including existing public roads, shall
be provided with facilities for adequate surface and subsurface drainage.
I. If subsurface drainage is deemed necessary by the
village, the subdivider shall provide for the same in a manner acceptable
to the Engineer.
J. Any areas of the subdivision which do not drain into
the subdivision drainage system shall be shown on the plan with a
note indicating disposition of water accumulating on such areas.
K. Drainpipes under roads or driveways shall be designed
to withstand New York State highway loadings.
L. Material requirements.
(1) A certified analysis of all intended material (includes
bituminous, culverts, concrete, gravel, stone, etc.) shall be filed
with the Engineer for approval prior to placing the material.
(2) The analysis may include an affidavit from the supplier
or may be made by a laboratory approved by the Engineer, or both,
as required.
M. Signs.
(1) Road name signs shall be provided at each road intersection
in the plat; letters shall be reflective and of a minimum four inches
in height.
(2) Traffic control signs shall be provided where designated
by the Highway Superintendent.
(3) All signs shall meet current village standards.
N. Turnarounds shall be provided as shown on Illustration
No. 2.
O. Construction methods.
(1) All brush, shrubs and roots thereof shall be entirely
removed from the right-of-way of all roads and alleys in the proposed
plat. All trees, including the roots thereof, within the roadway and
ditch lines shall be entirely removed. Trees outside the roadway and
ditch lines may not be removed unless approved by the village.
(2) All topsoil shall be removed from the roadway before
any surfacing material is placed. No topsoil or other fill material
may be removed from the subdivision without approval from the Planning
Board.
(3) Any deleterious material in the subgrade shall be
removed and replaced with material which is approved by the Engineer.
(4) The earth grade shall be brought to the required elevation,
smoothed, trimmed, drained and compacted before any surfacing material

be rolled and thoroughly compacted with a ten-ton roller.
(7) Upon completion of installing and compacting base
material, the entire roadway surface shall be treated with an asphalt
emulsion Type MC-30 at an application rate of 0.5 gallon per square
