Even person, firm, company or corporation making or causing
to be made any excavation in or under any street, highway, sidewalk
or public place, whether paved or otherwise, within the Village of
Briarcliff Manor, in compliance with Ordinance No. 92 of the Village
of Briarcliff Manor regulating the excavation of streets, sidewalks
or public places within such Village, shall, in making such excavations,
comply with the following regulations.
All locations and time of performing the work shall be approved
by the Superintendent of Public Works.
The permittee shall arrange his or its work so as to cause a
minimum of inconvenience and delay to vehicular traffic. The Superintendent
of Public Works reserves the right to order the removal of any and/or
all obstructions to traffic on Saturdays, Sundays, holidays and other
periods of unusually heavy traffic volumes. The permittee shall erect
and maintain suitable barricades to adequately delineate and protect
the site during and in which his or its work is in progress. Warning
flags, signs, flashing yellow lights and watchmen shall be provided
as necessary. Excavated material should be stored in neat piles, so
placed as to cause the least interference with the use of the roadway
or sidewalks. Where the free flow of traffic is interfered with, the
permittee shall place and maintain traffic control devices to adequately
warn and direct traffic in a manner acceptable to the Superintendent
of Public Works. All signs used at night shall be reflectorized with
wide-angle, flattop, reflective sheeting. All devices used both day
and night shall be mounted a minimum of five feet above the crown
of the pavement. Traffic control devices shall be placed at least
100 feet in advance of obstructions to adequately warn and direct
traffic. The Superintendent of Public Works reserves the right to
order the correction of any unsafe condition and the installation
of additional signs, lights or other traffic control devices.
Unless otherwise permitted, tight sheathing at least two inches
in thickness shall be placed in all trenches having a depth in excess
of four feet and within three feet of any pavement or other highway
structure which is proposed to remain in place except where excavation
is in rock. Sheathing shall be securely fastened in place with whalers
and braces during all operations and shall be driven to a depth one
foot below the lowest part of the structure proposed to be installed
as the excavation progresses. In all such excavations having a depth
in excess of six feet, such sheathing shall be left in place with
a cutoff line 18 inches below ground surface. In the trenches having
a depth of more than three feet and less than six feet, the sheathing
shall be left in place if ordered by the Superintendent of Public
Works. Sheathing may be omitted when permitted by the Superintendent
of Public Works if the edge of the proposed trench is offset from
the nearest edge of the pavement or other structure by a distance
at least equal to the vertical depth of the trench as measured from
the highest point of the adjacent pavement or structure.
Backfilling around completed structures shall be made of selected
material, free from loose stones, as soon as the structure has attained
sufficient strength to preclude injury and shall be made in successive
horizontal layers not exceeding six inches in depth. Each layer shall
be thoroughly compacted by tamping to the satisfaction of the Superintendent
of Public Works. No frozen material shall be used in the backfill.
Special care shall be taken to thoroughly compact the portion directly
under the haunches, around the sides and for a depth of one foot over
pipes or ducts. No rock shall be placed in the backfill within 12
inches of a pipe or duct. If permitted by the Superintendent of Public
Works, the backfilling of trenches may be thoroughly puddled by depositing
the earth in water. No backfilling of trenches by scrapers or other
machinery will be allowed, except that on longitudinal trenches outside
the pavement limits the use of power backfillers mounted on pneumatic
tires may be used if provisions are made for adequate compacting of
filled material. The work shall be so carried on that not over 300
linear feet of trench shall remain open at any time, unless otherwise
authorized by the Superintendent of Public Works.
All surplus excavated material and debris shall be cleaned up
and removed from the site of the work upon the completion of the work
by the permittee, leaving the site of the work in a neat and orderly
condition.
Where topsoil, seeded areas or sod are disturbed in the excavating,
the permittee shall restore the ground surfaces to the same conditions.
Manhole covers, frames and other structures placed within the
roadway limits shall be of sufficient weight and strength and of a
suitable type and stability approved by the Superintendent of Public
Works and shall be set flush with the surface of the pavement.
The permittee shall repair and maintain at his or its expense
any present or future disturbance of the roadway and pavement which
may have been caused by work done pursuant to the terms of the permit
herein, said maintenance to cover a period of 90 days after completion
of the work.
All small pipes or conduits crossing roadway pavements shall,
wherever possible, be driven beneath the pavement without disturbance
to the surface. Such pipes or conduits shall be enclosed in sleeves
or larger pipes, so that required replacements may be made in the
future without disturbance to the pavement. For the purpose of driving
such pipes or conduits, no opening of a trench shall be made closer
than two feet to the edge of the pavement. Tunneling under the pavement
is prohibited. Driving of pipes or conduits having a dimension greater
than eight inches shall be permitted only under such special terms
and conditions as the Superintendent of Public Works may prescribe.
Permanent restoration of the finished pavement shall not be
made until complete settlement of the trench backfill shall have taken
place, as directed by the Superintendent of Public Works. Immediately
after backfilling the trench, an acceptable temporary repair of cold
patch, bituminous macadam or other acceptable flexible pavement material
shall be placed which shall be maintained even with the roadway surface
until permanent restoration of the pavement is ordered by the Superintendent
of Public Works.
At such times as directed by the Superintendent of Public Works,
the permanent replacement of pavement shall be made under the supervision
and inspection of the Superintendent of Public Works, as follows:
A.
On concrete pavements which become undermined or broken, the slabs
shall be completely replaced on a prepared foundation with reinforced
concrete nine inches thick in the proportions of 1:2:3 1/2 using
high early-strength or quick-setting cement mixed by machine for at
least two minutes. Materials and proportioning of aggregate shall
be inspected and approved by the Superintendent of Public Works.
B.
When cross trenches are excavated vertically without undercutting
the concrete pavements, the slab shall be neatly cut back a distance
of at least two feet on each side of the outer walls of the trench
and replaced with a reinforced concrete patch. Where any portion of
a patch is nearer than eight feet to an expansion joint, the patch
shall be extended to the joint. Where longitudinal trenches have been
made in concrete pavements, the entire slab shall be replaced.
C.
In any event, the new patch must be reset upon undisturbed subgrade
for at least two feet in all directions from the excavated area and
must be at least 10 feet long as measured parallel to center line
of pavement. In removing portions of slabs or reinforced concrete,
care shall be taken not to remove all the reinforcing metal. New reinforcing
shall be carefully tied and bonded to old reinforcing steel when making
restorations. All reinforcement shall be three-eighths-inch bars,
spaced 14 inches in each direction. Approved premolded expansion joints
shall be inserted where directed, and all construction joints shall
be poured with an acceptable asphaltic material. The concrete shall
be completely wetted after placing and covered with six inches of
hay and kept continuously saturated for 10 days. The use of an approved
high early-strength cement, placed under approved methods, may be
required by the Superintendent of Public Works for certain concrete
pavement replacements where the delay and inconvenience to traffic
is of sufficient importance to warrant same. Satisfactory curing of
the concrete is of the greatest importance.
D.
On wearing surface pavements (asphaltic concretes and blacktops,
granite blocks, asphalt blocks, brick, etc.), a concrete foundation
eight inches in thickness shall be placed on a prepared foundation,
in the proportion of 1:2 1/2:5, using high early or quick-setting
cement in the same manner as reinforced concrete pavements. The concrete
shall be reinforced with approved wire mesh or three-eighths-inch
reinforcing bars, placed two inches above bottom of concrete. This
replacement shall cover an area for a distance of not less than two
feet on each side of the outer walls of the trench as excavated and
must be at least 10 feet long as measured parallel to center line
of pavement. This concrete foundation shall be completely wetted after
placing and kept covered with six inches of hay and kept continuously
saturated for eight days. After this curing is completed, a wearing
surface equivalent to pavement removed shall be placed in accordance
with New York State Department of Public Works specifications, as
directed by the Superintendent of Public Works.
The permittee shall replace or restore satisfactorily to the
Superintendent of Public Works any pavement or other structure which
may have been damaged during the progress of the work for which the
permit was issued even though such pavement or structure was not proposed
to be disturbed at the time of the granting of the permit.
A.
In lowering curb for driveways, only bluestone, granite or integral
curb will be allowed to be cut. All concrete curb must be removed
and replaced with new concrete curbing to the required height.
B.
On shoulder roads, the grade of driveway at the property line should
be the same elevation as the center line grade of the road. Modification
of this may be allowed if specifically permitted by the Village Engineer
or his authorized representative.
C.
Driveway entrances shall not begin within five feet of the point
where the prolongation of the property line meets the edge of the
pavement, unless otherwise authorized by the Village Engineer.
D.
Points of ingress or egress to a Village street must be approved
by the Village Engineer. Such points of ingress or egress shall not
be more than 30 feet wide measured at the pavement edge, unless special
approval is obtained from the Village Engineer or his authorized representative.
The Village reserves the right, however, to require the construction
of acceleration and deceleration lanes, together with channelization
at certain types of high-traffic-volume generating facilities.
E.
Driveways crossing sidewalks shall be constructed in accordance with
Village specifications.
F.
Wherever a driveway apron is installed, the area from the pavement
to the property line shall be paved in accordance with Village specifications.
