[Amended 6-13-2007 by Ord. No. 928-07]
The purpose of this chapter is to set certain standards for the design,
location and construction of driveways and driveway openings, and to ensure
the safe and clear passage of vehicles, in order to promote the safety, public
well-being, convenience and general welfare of the Township through, among
other things, the lessening of soil erosion, ensuring emergency vehicle access,
the promotion of traffic safety and the preservation of municipal road structures.
For the purpose of this chapter, the following words or terms shall
mean:
ALTERED
An existing driveway is "altered," within the meaning of this chapter,
when its horizontal location or vertical elevation is changed or when drainage
facilities are installed or replaced within the Township right-of-way. An
existing driveway is "not being altered" within the meaning of this chapter,
when it is paved, widened or narrowed.
DRIVEWAY
Any lane, way, opening, construction entrance or privately owned
road entering upon any public road within the Township of Clinton, including
access to farm buildings, except openings to nonresidential land used exclusively
for farming purposes.
UPHILL DRIVEWAY
A driveway whose grade rises in elevation from the existing grade
at the edge of the municipal roadway.
No driveway or field entrance may be constructed nor shall any existing
driveway or field entrance be altered within or along an existing Township
street unless the owner first obtains a driveway permit from the Township
Construction Department. The fee for such driveway permit shall be $25. The
applicant shall pay the Township an escrow fee of $250 to cover the cost of
professional review of the application by the Township Engineer, including
a site inspection of the construction and completion of the portion within
the Township right-of-way.
All driveways to be constructed or existing driveways to be altered
within any existing or future Township road right-of-way shall be constructed
or altered in accordance with the following minimum requirements:
A. Permitted slope at intersection. The portion of any driveway
within the road right-of-way shall be constructed so that the grade at the
right-of-way is not less than three inches nor more than six inches above
the edge of the existing pavement or traveled way.
[Amended 6-23-1999 by Ord.
No. 688-99]
B. Number.
(1) The maximum number of driveway openings permitted from
a commercial or industrial lot to any one road shall be limited as follows:
|
Length in Lot Frontage
(feet)
|
Permitted Number of Driveway Openings
|
---|
|
200 or less
|
1
|
|
201 or more

(2) The maximum number of driveway openings permitted from
a residential lot shall be limited as follows:
|

C. Adjacent driveway openings. Within the right-of-way,
a minimum distance of 25 feet shall separate any two driveways (on the same
premises or on adjoining lots) entering upon a single municipal roadway, as
measured parallel to the right-of-way line. A minimum distance of 10 feet
shall separate a driveway from an adjacent property line, within the right-of-way.
D. Adjacent property lines. A driveway may curve once it
leaves the road right-of-way, however, a minimum of 10 feet should remain
to separate the limits of any driveway, including the turnaround, from an
adjacent property line.
E. Drainage facilities. Each driveway shall be constructed
with suitable and adequately designed draining facilities. Wherever possible,
driveway drainage shall be directed into natural drainage channels. Driveway
drainage may be connected with existing drainage facilities within the municipal
roadway, provided that said connection does not interfere with existing drainage
or cause erosion or deposits of sediment in the municipal drainage system.
Driveway drainage systems shall not discharge onto adjoining properties causing
erosion or sediment damage or flooding and shall not discharge onto the paved
or traveled portion of any public right-of-way.
F. Sight distance required.
(1) All driveways shall be constructed in profile, grading
and location to conform to the following criteria:
|
Y = Sight distance along road, measured from Point A to Point C or from
Point D to Point C.
A & D = Point 4 1/4 feet above the road center line.
B = Point 3 1/2 feet above driveway center line, 20 feet from the
road's edge of pavement.
C = Center of the intersection.

(2) The entire area of the sight triangle, described by A-B-C
or B-C-D, shall be cleared as required to provide an unobstructed view across
it, from Point B to all points 4 1/4 feet above the road center line
between Points A and D.
All driveways constructed or altered within a Township road right-of-way
shall be constructed so as to be perpendicular to the existing pavement or
traveled way. Any curved or angular approach of the driveway for aesthetic
or topographical reasons shall be accomplished outside of the Township road
right-of-way, 25 feet from the center line of the existing roadway.
To assure adequate access for motor vehicles, any vertical curve on
a driveway shall be flat enough to prevent the dragging of any vehicle undercarriage.
Vertical curves shall not exceed a crest of 3 1/4 inches or a two-inch
depression in a ten-foot chord.
No new driveway shall be constructed at a profile grade exceeding 15%
at any point. If a proposed uphill driveway will exceed a profile grade of
8% anywhere within the first 200 feet, as measured from the road right-of-way
line along the driveway center line, then that portion of the driveway which
exceeds 8% within the first 200 feet shall be paved with a bituminous concrete,
macadam or portland cement concrete surface.
All driveways constructed or altered within the Township road right-of-way
shall be constructed in such a manner as not to interfere with the drainage
along the existing pavement or traveled way. Under no circumstances shall
the driveway be allowed to extend beyond the edge of the existing ditch line
at an elevation creating an uneven flow line in the gutter or ditch or beyond
the existing edge of pavement creating a hump or uneven driving surface.
The construction of a properly sized dish-type gutter will be permitted,
provided that the existing Township water flow will not be blocked, altered
or changed in any manner.
The installation of a suitably sized reinforced concrete pipe or culvert
will be required in the event that the existing flow line or ditch cannot
be crossed with a shallow dish-type gutter. The size of the pipe or culvert
required shall be determined by the Township Engineer and shall be a minimum
of 24 feet in length. In any event any pipe must be at least 15 inches in
diameter.
When a site or lot occupies a corner formed by two intersecting roads,
no driveway entrance or exit shall be located within 25 feet of the point
of tangency of the existing or proposed curb radius of either road.
No entrance or exit driveway shall be located on the following portions
of a road: a rotary, a ramp or interchange or within 25 feet of the beginning
of any ramp or other portion of an interchange. Driveways located on cul-de-sac
road turnarounds are permitted.
Any person or persons, firm, or corporation violating any provision
of this chapter which results in damage to or obstruction of any Township
road, gutter, storm drain, ditch, basin, inlet or culvert shall be responsible
for all expenses incurred by the Township in repairing the damage or removing
the obstruction, in addition to the penalty herein provided.
Any person or persons, firm, or corporation violating any of the provisions of this chapter shall, upon conviction thereof, be subject to the penalty stated in Chapter
1, §
1-17.
