Unless otherwise specified by the Borough, all
work shall be performed in accordance with New Jersey Department of
Transportation Standard Specifications for Road and Bridge Construction,
1989, as amended. These specifications shall govern the installation
and construction of improvements in all sections of subdivisions,
final plats of which have not received formal Borough approval prior
to the effective date of this chapter and to all construction work
hereafter performed on previously approved final plats where adherence
to the new specifications will not impose unnecessary hardship by
reason of prior commencement of such construction, prior commitments
of contracts or prior delivery of materials.

B. Joint filler shall be cellular compression material
conforming to the requirements therefor of the Standard Specifications
of the New Jersey State Highway Department, as amended and revised
to date.
C. Methods of construction.
(1) The contractor shall make all necessary excavations
or embankments for the construction and disposing of surplus materials.
No filling shall be done below the proposed curb or gutter except
when absolutely necessary, in which case such fill shall be made with
clean sand or approved gravel and thoroughly tamped before concrete
is laid thereon. All soft spots shall be thoroughly tamped, or, if
necessary, soft or spongy material shall be removed and clean sand
or approved gravel refilled in its place.
(2) Backfill for curb. Within 72 hours after curbing is
completed and forms removed, the contractor shall backfill to the
top of the curb in back and to the established gutter grade in front.
Backfill shall be made with the materials excavated, except that any
large or frozen lumps, wood, boulders or other foreign matter shall
be removed before placing. Backfill shall be thoroughly compacted.
(3) Forms. Forms for concrete may be of lumber or steel.
They shall be straight and of sufficient strength to prevent warping
or bulging and to retain the concrete accurately in position. All
mortar and dirt shall be removed from forms which have been previously
used. Forms shall be well staked to the proposed lines and grades,
and their upper edges shall conform to the finished surface of the
curb. All forms shall be thoroughly wetted immediately before concrete
is deposited against them.
(4) Concrete. Concrete construction, including curing,
shall conform to the applicable requirements of the section on concrete
structures contained elsewhere herein. The concrete shall be tamped
and spaded or vibrated so that the forms are completely filled, the
concrete thoroughly compacted and mortar flushed to the face and top.
(5) Joints.
(a)
Concrete curb and gutters. Expansion joints
shall be provided at intervals of 20 feet or when new construction
abuts existing construction. The expansion joints shall be filled
with one-half-inch-thick cellular compression material to within 1/2
inch of the top and face of the curb and to within 1/4 inch of
the top of the gutter. Dummy joints shall be provided at alternate
twenty-foot intervals.
(b)
Concrete sidewalks and aprons. Expansion joints 1/2
inch wide shall be provided at intervals of 20 feet where the new
paving abuts the curb or old work. The expansion joints shall be filled
with one-half-inch-thick cellular compression material to within 1/4
inch of the top of the paving. For sidewalks, surface grooves shall
be cut with an approved tool at least 1/4 inch thick at right
angles to the line of the sidewalk and at intervals equal to the width
of the sidewalk. Where new work abuts the existing sidewalk, the surface
grooves shall be spaced to conform to the lines of the abutting walk.
All surface edges shall be rounded to a radius of 1/2 inch.
(6) Curb finish. Before initial set, the top of the curb
and the gutter shall be finished with a wood float to an even, smooth,
dense surface. As soon as the forms can be removed, the face of the
curb shall be given the same finish. Exposed edges shall be neatly
rounded to a radius of 1/2 inch. The finished curb shall be true
to the required grades, lines, dimensions and curvatures. Completed
work shall be protected from traffic and the elements and shall be
thoroughly wetted and kept moist for at least one day. Damaged, broken
or cracked work shall be renewed by the contractor at his own cost
and expense.
(7) Finishing of concrete sidewalks and aprons. The finish
shall be with a wood float, followed by brooming to a neat and workmanlike
surface. Exposed edges shall be neatly rounded to a radius of 1/2
inch. The concrete shall be cured as provided elsewhere herein. The
sidewalk and grass shall slope at a rate of 1/4 inch per foot
toward the top of the curbline except as otherwise amended by the
Borough Engineer.
(8) Concrete work in cold weather. No concrete shall be
poured between December 1 and March 1 of each year without the prior
expressed written permission of the Engineer. Where such written permission
is obtained, the Engineer shall specify the appropriate procedures
to be followed from the Standard Specifications, requirements of which
shall also apply from March to November in cold weather conditions.
(9) Concrete curb. Concrete curb shall be constructed
in accordance with Division 5, Section 5, of the Standard Specifications,
except that the mixture shall be as designated in these specifications.
True joints shall be placed on the curb at twenty-foot intervals.
Backfilling for curbs shall be made within 72 hours after construction.
Curb dimensions shall be six inches wide at the top, nine inches wide
at the bottom and 18 inches deep. Unless otherwise required by the
Engineer, the reveal shall be six inches, except at driveways where
a two-inch reveal shall be used. Where the curb is to be constructed
along lines having a radius of 250 feet or less, securely anchored
curved forms will be permitted for a curved curb where the radius
exceeds 250 feet, provided that the ends of the tangents are finished
to prevent the appearance of sharp angles. At street intersections,
the curb corners shall have a minimum radius of 25 feet unless conditions
are such that the minimum radius of 25 feet is not practical. Where
such conditions may occur, the owners shall obtain written permission
from the Engineer to decrease the radius.
Fire hydrants shall be as manufactured by the
Kennedy or Mueller Valve Company or other approved by Fire Marshal.
Operating and cap nuts shall be one-and-one-half-inch pentagon. They
shall be equipped with two hose nozzles and one steamer nozzle, size
and threads to be in accordance with local fire company requirements.
They shall have a provision for a six-inch connection to the main.
The minimum valve opening for the hydrant shall be 4 1/4 inches.

A. All applicants for residential construction permits shall have the
application reviewed by the Zoning Official and/or Borough Engineer
to determine whether a topography and grading plan is required to
be filed as part of the approval process by the Borough for the issuance
of a construction permit. A topography and grading plan shall be a
mandatory requirement for construction in connection with all major
subdivisions. For minor subdivisions and construction over 200 square
feet and individual lots, the determination of whether a topography
and grading plan is required shall rest with the Borough Zoning Official
and/or Borough Engineer.
B. In the event a topography and grading plan is required, the applications
shall be reviewed and approved by the Borough Engineer. All lots shall
undergo a final inspection of the grading, to be performed by the
Borough Engineer. Following final inspection of the site, a written
report shall be prepared by the Borough Engineer.
C. The lot grading plan must be prepared by a New Jersey state licensed
land surveyor and New Jersey licensed professional engineer. All proposed
grading plans shall be prepared to avoid an adverse impact on all
adjoining or adjacent properties. The plan must depict the following
items:
(1)
Outbounds and topographic survey, including the depiction of
any existing or proposed easements. The topography shall include contours
at one-foot intervals and spot elevations at all property corners,
low or high points and other distinct topographic features. Existing
and proposed contour lines and spot elevations of the parcel, as noted
above, and for 50 feet surrounding the parcel.
(2)
All zoning setback lines and proposed building setbacks.
(3)
Location and elevation of all existing improvements and/or utilities
and all proposed improvements, including, but not limited to, accessory
buildings, curbs, sidewalks, driveways, patios, decks, pools, fences
and utility service lines.
(4)
The proposed building basement floor, garage floor and finished
first floor elevations, proposed contour lines at one-foot intervals
and proposed spot elevations shall be shown at building corners, proposed
swales, curb, sidewalk and driveways.
(5)
When curb and sidewalk is proposed along a street, the grading
plan shall also include spot elevations along the center line, edge
of paving, proposed gutter line and top of curb and sidewalk at intervals
no greater than 50 feet. A profile depicting these elevations and
proposed design shall be included with the grading plan.
(6)
The location and elevation of buildings on adjacent lots.
(7)
All wetlands and wetlands buffers.
(8)
Grading plans illustrating existing and proposed spot grade
elevations and contours must be provided for all proposed pool construction,
landscape hardscaping, building additions and single-family home construction.
(9)
Backhoe test pits must be performed to document subsurface soil
stratum and the seasonal ground high water table for all proposed
single-family home construction. Finished basement floor elevations
must be constructed one foot above the estimated seasonal high groundwater
table.
D. The fee(s) payable hereunder shall be as set forth in Chapter
73, Fees.

A. The State of New Jersey, through the Uniform Construction Code, requires
that a foundation location survey be submitted to the Borough Construction
Official as soon as possible after the installation of the foundation
wall. This plan shall be prepared by a land surveyor licensed by the
State of New Jersey and show all building corners of the foundation.
To confirm that the top of block elevation conforms to the approved
plan, the permittee shall also submit a foundation location plan to
the Borough Engineer for review. The foundation plan shall contain
the top of the block.
B. Nothing in this section shall prohibit a permittee from commencing
with framing prior to the submission of the foundation location plan
to the Engineer but will instead be a matter to be resolved by the
contractor prior to the issuance of the certificate of occupancy.
However, since the permittee shall demonstrate conformance to the
performance standards to the issuance of the certificate of occupancy,
it is recommended that the foundation location plan be submitted to
the Engineer as soon after the installation of the foundation walls
as possible.
