A.
General Information. A driveway construction permit must
be obtained from the Road and Bridge Department or Planning and Zoning
Department before construction of any driveway entrances (temporary
or permanent). Driveway culverts shall be located to conform to the
existing ditch line(s) or as directed by the Road and Bridge Department.
The Road and Bridge Department must approve driveway culvert pipe
size before installation. All driveway corrugated rib culvert pipes
shall be fifteen (15) inches in diameter minimum (may be twelve (12)
inch diameter if steel smooth pipe) and thirty (30) feet minimum in
length. The maximum length is sixty (60) feet.
B.
All
driveways shall be constructed in such a manner as not to divert drainage
to the roadway.
C.
Culverts
installed by property owner not meeting the specifications and/or
causing drainage problems may be removed as necessary to correct the
drainage problem. Costs of new installations shall be borne entirely
by the property owner.

A.
Preparation
for issuing a driveway permit must include a prior inspection of the
driveway site to insure that vehicles can enter and exit from the
proposed driveway with a minimum hazard and disruption of traffic
along the roadway.
B.
Sight
distance for driveway construction should be considered essential
in the design of commercial or industrial type driveways and desirable
with respect to residential driveways. If there is a request to construct
a driveway at a questionable location, a traffic study must include
an on-site inspection to valuate the sight distance.
C.
There
are two (2) basic concerns of responsibility when considering the
sight distance requirements for any driveway.
D.
Fortunately,
adjacent property owners who are constructing new driveways to an
existing road are usually anxious to consider the safest location
for a driveway.
E.
The
following criteria based on the American Association of State Highway
and Transportation Officials (AASHTO) guidelines and the Design Manual
has been developed in order to establish a uniform method of determining
the necessary sight distance for a driveway constructed by permit.
There are two (2) different sight distances used. They are:
F.
All
sight distance measurements are based on a three and one-half (3.5)
foot height of eye and a four and one-quarter (4.25) foot height of
object. The use of the four and one-quarter (4.25) foot object is
based on fact that typically the only change in the roadway is that
there is now an additional entrance to the roadway and a vehicle is
the expected object using the driveway and the existing route. Cass
County road and bridge personnel must review the minimum entrance
stopping sight distance.
1.
If the driveway location meets or exceeds the requirements for the
decision sight distance for the posted speed of the roadway as established
in Table 10, a permit may be written.
2.
If a driveway location within the limits of the property frontage
has less than the decision sight distance, but equal to or more than
the minimum stopping sight distance, a permit may be written for the
driveway construction but must include the applicant's responsibility
clause as follows: "Applicant understands the presence of this driveway
creates a potential sight distance problem and has been so informed
in writing by the department". In this instance, it is imperative
that property owners be on the site to be certain they understand
the conditions of this driveway construction.
3.
If the measured sight distance is less than the minimum decision
sight distance and greater than the minimum stopping sight distance,
Cass County road and bridge personnel must review the minimum stopping
sight distance. If the review substantiates that minimum stopping
sight distance measured for the proposed driveway is greater than
the minimum stopping sight distance shown in Table 10, the Road and
Bridge Department may approve the driveway location if all of the
following conditions are met:
a.
The proposed driveway location has the maximum sight distance available
for the property frontage. The applicant should be advised of minor
work on their property, which could improve sight distance such as
minor grading or brush removal.
b.
There is no other access available, which has greater sight distance
(i.e., City street or cross access).
c.
The applicant agrees to sign the permit application that states in
addition to the normal responsibility clause the following statement.
"Applicant is aware that the sight distance of this driveway is severely
restricted. The sight distance is the minimum distance necessary for
a vehicle traveling at the posted speed to complete a stop prior to
the driveway." If these conditions are not met, the permit may not
be issued for the driveway.
4.
The County may allow the widening of a driveway with limited sight
distance or may allow the relocation of a driveway with limited sight
distance to a location on the property frontage with better sight
distance. This will be allowed on routes with normal right-of-way,
provided there is no change in driveway usage. The following responsibility
clause must be added to the permit. "Applicant understands that the
existing sight distance for this driveway is less than current design
standards and the driveway modification, while beneficial to the property
owner, will not remedy the sight distance limitation."
Both vertical and horizontal alignment can limit sight distance.
In order to measure actual sight distance limited by vertical alignment,
place a sighting target four and one-quarter (4.25) feet above the
edge of pavement at a point twelve (12) feet from the edge of pavement
(approximate location of a driver approaching the roadway) at the
proposed driveway location. Sighting from a height of three and one-half
(3.5) feet, move along the roadway away from the proposed driveway
site to a point beyond where the target disappears. Now move toward
the target until it can first be seen and place a mark on the pavement.
Measure the distance along the roadway between the mark and the target.
Measurement may be made with an accurate measuring device mounted
on an automobile. This measured distance is the sight distance.
Even when the applicant is present, sight distance measurements
in terms of feet may be difficult for an applicant to understand when
it comes to getting on and off the roadway. A measurement of time
lapse may help the applicant get a better understanding of the critical
nature of the situation.
A sight distance visibility time for the driver exiting a driveway
to see an approaching vehicle can be used. A value of three (3) seconds
enables a stopped passenger car to cross a two-lane highway. A value
of seven (7) seconds allows vehicles exiting the driveway to turn
left or right onto two-lane roads without interference (slowing down)
of through traffic at speeds up to thirty-five (35) mph.
Trucks require greater sight distance than needed for passenger
cars, however, the greater driver eye height, typically over six (6)
feet, provides an allowance for vertical curve conditions. If the
obstruction to sight is a horizontal curve or other lateral blockage,
a fifty percent (50%) increase in visibility time is recommended.
Grading on the right-of-way to improve sight distance should
be considered and included in the permit for driveway construction.
Public street entrances should meet or exceed decision sight
distance.
