[Added 6-10-2003 by Ord. No. O-10-2003] | |||
(a)
|
Purpose. The purpose of this subsection is to
set certain standards for the design and location of driveways and
driveway openings for new single-family residential dwellings in order
to promote the public safety, well being, convenience and welfare
of the Township of Franklin and to provide adequate access to properties
for emergency service vehicles.
| |||
(b)
|
Permit requirements. The proposed driveway location
and details shall be included on the plot plan submitted in conjunction
with the application for a zoning permit, as well as the access easement
and maintenance agreement for shared driveways. The location and layout
of the driveway, including width of cartway and cleared areas, shall
be accurately shown on the as-built survey of the property submitted
prior to issuance of a certificate of occupancy.
| |||
(c)
|
Minimum design standards. All driveways shall
be constructed in accordance with the following minimum requirements:
| |||
[1]
|
Shared driveways are encouraged for new developments
subject to review and approval of the access easement and maintenance
agreement by the reviewing agency.
| |||
[2]
|
Driveways shall be set back a minimum of five
feet from the side property line, with a minimum separation of 10
feet between adjoining driveways.
| |||
[3]
|
Driveways shall intersect the public way at
an angle to as near 90° as site conditions will permit and in
no case less than 60°.
| |||
[4]
|
Driveways shall have a minimum cartway width
of 12 feet and shall be surfaced with a minimum of six inches of compacted
gravel or quarry blend. A minimum ten-foot-long paved apron (either
asphalt or concrete) at the street intersection. The minimum driveway
width plus a two-foot-wide strip on each side shall be kept cleared
of vegetation which may hinder vehicle passage, or other obstructions
which may restrict vehicle passage and limit driver view of vehicular
or pedestrian traffic on the driveway, sidewalk or public right-of-way.
This cleared width shall extend from one-foot above the driveway surface
to a height of 14 feet and shall be properly maintained to preserve
the public safety.
| |||
[5]
|
Any horizontal curves in the driveway shall
have a minimum inside radius of 40 feet.
| |||
[6]
|
Any vertical curve on a driveway shall be flat
enough to prevent the dragging of any vehicle undercarriage.
| |||
[7]
|
Where access is provided to a street or road
where the speed limit is over 25 miles per hour, the driveway shall
incorporate a turnaround area to avoid the need for vehicles to back
out into the street.
| |||
[8]
|
Driveways over 500 feet in length shall provide
a midpoint passing area where the compacted surface is expanded to
a minimum width of 18 feet for a minimum distance of 25 feet.
| |||
[9]
|
All driveways shall be constructed at such an
angle so as to assure maximum visibility in all directions at the
point of entry to the street, taking into account physical obstructions
which may be present and which cannot be removed or modified. Any
obstructions to vision which can be removed or modified by the person
seeking to construct the driveway should be so removed or modified.
| |||
[10]
|
The house number shall be displayed near the driveway intersection with the adjacent street as required pursuant to Chapter 165 of the Code of Franklin Township.
|
n = 0.015 concrete pipe.
n = 0.024 corrugated metal pipe (annular corrugations).
n = 0.019 corrugated metal pipe (helical corrugations).
The minimum allowable pipe size is 15 inches.
|
H = 0.2 feet = 0.8(D1 - D2) feet
| ||
Where
| ||
D1 = Diameter of inlet pipe.
| ||
D2 = Diameter of outlet pipe.
| ||
If D1 is larger than D2, head loss is 0.2 foot.
|
Where
n = 0.015 best concrete lined ditch.
n = 0.025 best unlined ditch.
n = 0.03 to 0.05 fair to poor natural streams
and watercourses.
