In all cases, a minimum clear distance of 50 feet measured along
the right-of-way line shall separate the closest of any two driveways.
A. The beginning of the driveway shall have a grade of not more than
6% for a distance of 25 feet from the beginning of the driveway and
not more than 15% for any other portion of driveway.
B. Where driveways are at a higher elevation than the street and where
the driveway grade exceeds 8% at any point within 250 feet of the
public right-of-way, the following shall be performed:
(1) The driveway shall be paved in accordance with §
11-230 following.
(2) The pavement shall extend from the right-of-way line to a point at
which the grade is less than 8% or for a two-hundred-fifty-foot distance,
whichever is less.
(3) The above pavement shall be in addition to the required pavement
for the first 25 feet.
(4) Where applicable, the applicant should submit a detail showing the
above, including details of storm drainage system to control runoff.
The side lines of a proposed driveway shall be no closer than
10 feet from any property line.
[Amended 12-22-2005 by Ord. No. 05-22]
All driveways shall have a minimum driving width of 12 feet
and a maximum driving width of 25 feet.
[Amended 2-8-2002 by Ord. No. 02-3, 12-22-2005 by Ord. No. 05-22]
Guiderails shall be required where, within 10 feet of the driveway,
there exists either an embankment descending more than six feet or
an embankment ascending at a ratio exceeding four to one.
Where curbs exist, a full section of curb shall be entirely
removed and depressed curb constructed in accordance with the New
Jersey Department of Transportation, Standards for Roads and Bridge
Construction, 1983, as amended. Curb radii of existing curb shall
not be broken or depressed. No driveway shall be located closer than
50 feet from the end of the radius of an intersection.
Where concrete sidewalks exist or are proposed to be constructed
as part of the project, a concrete ramp not less than six inches in
thickness shall be built connecting the inner edge of the depressed
curb with the outer edge of the sidewalk.
In cases where drainage exists along the township road, a reinforced
concrete pipe of a size determined by the Rational method of runoff
calculation shall be installed beneath the drive by the owner and
inspected by the Township Engineer. If more than one driveway is constructed,
a continuous storm drain pipe shall be installed between the driveways
or connected to an intervening storm drainage system. If the proposed
drainage pipe connects with an existing storm drainage system, a catch
basin shall be constructed.
All construction within the township right-of-way shall be in
accordance with the New Jersey Department of Transportation, Standard
Specifications for Road and Bridge Construction, 1989, as amended.
The owner shall properly safeguard all work during construction
and shall maintain sufficient warning lights or other such devices
during the hours of darkness.
The work shall be so conducted that there will be no interference
with the drainage or cross section of the township road, nor any structures
over or under the road except as indicated in the approved plans.
The applicant shall make certain that all appropriate erosion
control measures are adhered to during and after construction of the
driveway.
That portion of any drive or driveway for a single-family dwelling
within the right-of-way of a township road shall be constructed of
not less than six inches, when compacted, of gravel, Type II, Class
B, and a wearing surface of bituminous concrete two inches thick,
FABC-1, constructed on the gravel base. Finished grade of the wearing
surface of the driveway shall be level with or lower than the edge
of pavement of the roadway for a distance of at least three feet from
the edge of pavement. Driveway construction details within the township
right-of-way for other than single-family dwellings are as follows:
A. Six inches gravel Type II Class B (compacted).
B. Four inches stabilized base.
A. Grass areas disturbed shall be restored to a stable condition in
preparation for topsoiling and seeding. There shall be no evidence
of stones, roots, debris or depressions and the surface shall be clean
and even. The subgrade immediately prior to the application of topsoil
shall be raked or otherwise loosened.
B. The topsoil shall be applied over the surface in a uniform layer
that will produce a thickness after compaction of approximately four
inches. Ground limestone fully protected from moisture, and free flowing,
shall be evenly spread over the area to be seeded, at the rate of
40 pounds per 1,000 square feet. This shall then be raked, disked
or otherwise worked to incorporate the limestone into a minimum of
three inches soil depth. All foreign and unsuitable material shall
be removed and the surface shall present an even appearance. For small
seeded areas, asphaltic oil will not be required. The mulch shall
be held in place by the use of netting, twine or lath or as directed
by the Township Engineer. Where a stand of grass practically weed-free
is not established during this operation, the deficient areas shall
be refertilized and reseeded as directed by the Township Engineer
until a satisfactory growth of grass is established. All waste material
and debris resulting from topsoiling, fertilizing and seeding shall
be removed and disposed of in a proper manner.
The Township Engineer may impose such other construction requirements
within the township road right-of-way as the Engineer deems appropriate
in order to properly protect the traveling public and the township
road and drainage facilities.
Prior to the issuance of the permit, the applicant shall present
satisfactory proof to the Township Engineer that he or she has notified
the utility company of his or her intent to excavate.
If the applicant can clearly demonstrate that, because of peculiar
or unusual conditions pertaining to his or her land, the literal enforcement
of one or more of these regulations is impracticable or will exact
undue hardship, the Approving Board may permit such minor deviation
as may be responsible and within the general purpose and intent of
these regulations and standards.
The owner shall save harmless, in writing, the Township of Knowlton,
its officers and agents from and against any loss, injury or damage
resulting from any negligence or fault of the owner or his or her
agents in performance of the work covered by an approved permit.
A. Prior to the construction, reconstruction or alteration of an entrance
or exit drive onto a township road or common driveway, the owner of
the property or his or her duly authorized agent shall make application
for a driveway permit to the Township Driveway Official on forms provided
by the Township of Knowlton.
[Amended 4-23-1998 by Ord. No. 98-3]
B. Such application shall be accompanied by required fees and bond,
together with three copies of a plot plan of the property drawn to
a scale not greater than one inch equals 30 feet showing the location
of the proposed driveways in relation to all existing and proposed
driveways, intersections, streets, drainage structure or other structures
within 200 feet of the proposed driveway location. The maps will also
include a profile, at a scale no greater than one inch equals 30 feet,
of the proposed driveway location from the center line of the township
road to a point at least 40 feet from the existing edge of pavement
of the township road.
C. Driveways accessing county roads will require township driveway permits
in addition to the required county driveway permit, with the following
modifications:
(1) County standards will apply to that portion of the driveway within
the county right-of-way. Township standards will apply for balance
of driveway.
(2) No township fees or deposits shall be required for driveways accessing
a county road provided applicable fees and deposits have been deposited
with the county.
D. In the case of an applicant for a driveway permit for an existing
lot, the Driveway Official or the Township Engineer shall review the
plans and application submitted pursuant to this section and in accordance
with the provisions of Roadway Design Standards. In the event that
the driveway does not meet the above standards, the Driveway Official
or the Township Engineer shall deny the driveway permit or modify
the application to provide compliance with the standards or, for good
cause, may recommend waiver of the standards to the Planning Board,
in writing. In addition, the Township Engineer or Driveway Inspector
may request recommendations and/or input from the Knowlton Township
Fire and Rescue Squad. The Planning Board shall review the recommendation
for waiver with such information as may be required by the Planning
Board being provided by the applicant. The Planning Board may grant
a waiver of said standards if it finds that the waiver will not adversely
impact traffic safety on the abutting roadway and will not adversely
impact the subject property or surrounding properties and that the
benefits derived from the grant of the waiver will outweigh the detriments.
[Amended 2-8-2002 by Ord. No. 02-3]
E. If an applicant for subdivision or site plan approval can clearly
demonstrate that, because of peculiar or unusual conditions pertaining
to his or her land, the literal enforcement of one or more of these
regulations is impracticable or will exact undue hardship, the Approving
Board hearing the application may permit such minor deviation as may
be reasonable and within the general purpose and intent of these regulations
and standards.
F. Upon review and approval of the design of the driveway construction
plans, the Township Engineer may or may not recommend to the Driveway
Official that the permit be issued. The Township Engineer or the Driveway
Official shall periodically inspect the premises during construction
to ensure compliance with the terms of the permit and shall endorse
the road permit when all construction is completed in accordance with
the approved plans. The Township Engineer shall notify the Township
Road Supervisor of all driveways and other road openings that have
been approved and a copy of the application, map and conditions of
approval shall be sent to the Township Driveway Official. The applicant
shall provide a performance bond or cash in an amount required by
this chapter to ensure that the improvements will be constructed in
accordance with the plan approved by the Township Engineer or Driveway
Official. The cash or bond will be released upon the satisfactory
completion of the improvements and after approval and recommendation
by the Township Engineer or the Driveway Official.
Any person or persons violating any provision of this section
which resulted in inconvenience to the public or damage to or obstruction
of any township road, gutter, storm drain, catch basin, inlet or culvert
shall be responsible for all costs and expenses incurred by the Township
of Knowlton in repairing the damage or removing said obstruction,
in addition to any penalties provided herein, and shall be responsible
for damages to any persons so inconvenienced.
Prior to the issuance of the permit, the applicant shall present
satisfactory proof to the Driveway Official that he or she has notified
all utility companies of his or her intent to excavate.
