REVIEW OF KETTLEMAN
LANE TRAFFIC REPORT
Councilwas reminded that, earlier in the summer, it
expressed concerns over traffic congestion and striping
RES. NO. 87-137
inconsistencies on Kettleman Lane (State Highway 12).
Staff toured Kettleman Lane with Councilmembers and later
CC -45(a)
with Caltrans representatives. Staff provided Council with
CC -48(a)
copies of its letter to Caltrans and their response. The
--
main points, comments, and recommendations are .as follows;
I) Right Turn Lane Striping - Caltrans indicated right
turn lanes are insta led based on their judgment as to
-- -
- where they are needed, generally in response to ---- -
accidents or congestion. They also acknowledged the
inconsistency with red curb and indicated we could
paint the curbs at existing right turn lanes. We
would not do so without Council approval.
The following list shows all the existing right turn lanes,
p'
red curb status, and our comments/recommendations:

Whether or not Caltrans actually develops right turn
- lanes at additional intersections, staff feels there
- is value in painting additional red curb at all
intersections on Kettleman Lane. At Staff's meeting
with Caltrans engineers, they suggested a 100' curb
length on Kettleman Lane be established as no parking
f
and a maximum of 50' of red curb on the side street
g
approaches. This would improve sight distance for
both vehicles and pedestrians and allow room for
_
turning vehicles on both streets. Due to driveways,
fire hydrants, and other factors such as parking
demand, the actual amount of red curb would vary at
=i
each street. Council should provide some direction to
staff if it wishes this implemented. We could then
bring back to the City Council specific
recommendations at each location.''
2) Seed Zones - Caltrans updated the speed surveys and
is changing the speed limit from 40 mph to 45 mph on a
portion of Victor Road. The other limits are
appropriate.
3, 4) Left Turn. Access/Medians - Caltrans was fairly
noncommitta on t e su sect of medians. The cost of
landscaped median on Highway 12 through the City would
be well over $400,000. Several traffic studies in
other jurisdictions have indicated that raised
f
"
medians are preferable to two-way left turn lanes on
streets having six through lanes or daily traffic over
approximately 25,000. Kettleman Lane is wide enough
a--
for six lanes and.the volumes are in the low 20,000s.
Staff recommends that this improvement be considered
in the General Plan update.
5)
Projected Volumes - Caltrans' volumes 'near or
between the streets indicated are: '
YEAR: 1986 1995 2005
Kettleman Lane
Ham Lane
14,000 20,900 27,000
Hutchins Street
21,100 27,000 32,300
11,700 17,500 22,500
Cherokee Lane
8,000 12,000 15,500
Highway 99
The
City's General Plan update will include a new estimate
of
these volumes.
5)
Signal Coordination - As of August 17, the Ham and
Cherokee intersections have been added to the State's
coordination plan. However, they are still finding
"bugs" in the timing programs. In general, under a
time base coordination plan, the signals will not be
as responsive to side street traffic and the cycle
lengths will increase. Caltrans (and City staff) will
continue to monitor these improvements.
7)
Planned Maintenance - Based on our conversations, it
appears an over ay on Kettleman Lane is three or five
x
years away. Victor Road was chip sealed this summer.
8)
Driveway Widths - We reached an understanding that
driveways designed as a street intersection, similar to
that at Kettleman Station opposite Central Avenue, are
.
not limited to 40 feet in width.
9)
Eastbound Traffic at Cherokee Lane - As noted in
-
Caltrans' etter, t ere is a pro em with eastbound--
traffic at Cherokee Lane. In order torovide the
P _
-
additional lane and remove the forced right -turn only
lane on Kettleman at Cherokee, a no parking zone in
front of Carrow's Restaurant and the ARCO Station is
=
needed. Staff concurs with the State's recommendation
that this be done.
10)
Accident Records - The computer printouts of segment
and intersection accident rates on Highway 12 indicate_
higher rates than "expected" oraverage rates for
similar highways. These should be viewed with caution
as the segments are relatively short -and the indicated
side street volumes are lower than current traffic
volumes. These factors tend to inflate the accident
rate. Caltrans did not feel there is a significant
accident problem on Highway 12 in general.
A lengthy discussion followed with questions being directed
to Staff. _
Mr. Bill Rude, Carrows Restaurant, Lodi, addressed the
Council asking that the street parking in the area of
Carrows Restaurant not be removed.
Following additional discussion, Council, on motion of
Mayor Pro Tempore Snider,. Olson second, adopted _Resolution
No. 87-137 1) establishing "No Parking" zones at the
existing eastbound right turn lane on Kettleman Lane at Ham
Lane and 2) established "No Parking" zones on both sides of
Kettleman Lane between School Street and Stockton Street
(underpass).

MEETING DATE: October 14, 1987
AGENDA TITLE: Review Kettleman Lane Traffic Report (Discussion and
Appropriate Action)
RECOMMENDED ACTION:
1) Establish no parking zones at existing right turn lanes on Kettleman Lane.
2) Establish no parking zones on both sides of Kettleman Lane between
School Street and Stockton Street (underpass).
3) Establish a no parking zone on the south side of Kettleman Lane from
Cherokee Lane to the Highway 99 offramp.
BACKGROUND INFORMATION: Earlier in the summer, Council expressed concerns
over traffic congestion and striping inconsistencies on Kettleman Lane (State
p
Highway 12). Staff toured Kettleman Lane with Councilmembers and later with
s
Caltrans representatives. Our letter to Caltrans and their response are
attached. The main points, comments, and recommendations are as follows:
1) Right Turn Lane Striping - Caltrans indicated right turn lanes are
installed based on their judgment as to where they are needed, generally
in response to accidents or congestion. They also acknowledged the
inconsistency with red curb and indicated we could paint the curbs at
existing eight turn lanes. We would not do so without Council approval.

Dear Mr. Ronsko:
July 3, 1987
10-S7-12-16.4/18.1_
Ham Lane to. Rte 99
This is in response to your letter of May 8, 1987, and confirms my meeting of
May 29, 1987, with Richard Prima and Paula Fernandes of your staff.
1. Right turn lane striping -- risere appears to be a lack of consistency in
our treatment of mandatory right turn lanes off Kettleman Lane (Route 12)
in that some of thea have red painted curb and others do not and sane have
arrows while still others do not.
We will proceed with painting the arrows where necessary. However,
normally, Caltrans doss not paint curb: local agencies may do so after en-
acting a resolution to restrict parking and submitting it to us for ap-
proval. In the case of Kettleman Lane, since the locations under
discussion are right turn lanes and any parked vehicles will constitute
hazards, no resolution is necessary and the City may paint the curb when
ready.
2. Speed Zones -- Speed data have been gathered on both Kettleman Road and
Victor Road; preliminary indications are that the zoning on-Kettleman Will
remain as is. However, that on Victor Road may have to be raised to main-
tain conformance With the Traffic Manual.
3. Left turn access — This should be considered in conjunction with the fol—
lowing item since they are somewhat mutually exclusive.

4. Medians — Caltrans is not wholly averse to the idea of a median between
Ham Lane and Highway 99 on,Kettleman_ It would concentrate all left turns
at the intersections which may reduce total accidents. We see two poten-
tial problems:
a. Will the local merchants accept it?
b. There may be enough demand for U-turns that it increases weaving moves
and congestion, resulting in no change in accident level, possibly
even an increase.
5. Projected volumes — These were provided to Rich at our meeting; if addi-
tional data are desired, please contact either Bill Zieker at 948-7168 or
Bcb Mah at 948-7868.
6. Signal coordination — Time base coordination programming and timing is in
place at Stockton St., Church St. and Hutchins St. and is undergoing peri-
odic testing. Initially, same programming problems occurred but they have
been resolved. Timing plans which include Cherokee Lane and Ham Lane in
the coordinated system have been developed but are not installed as yet.
This will be done as time permits; we have only one person for this work
and he is spread very thinly.
7. Planned pavement maintenance — Portions of Route 12 through Lodi have
been identified for rehabilitation but since they are in a relatively good
state of repair, have a low priority and will not be funded for several
years. If you have any questions regarding this, please contact Allan
Wells at 948-7300 or Dennis Smith at 948-7859.
8. Driveway widths — The case in point was a driveway which was to be lo-
cated opposite a city street. If the driveway is configured to look like
a city street and it operates much as a street would, it can be con-
structed to the same width as the street opposing, and not be constrained
by the normal 35' guideline. A side benefit is that, should signalization
be required, it would be simpler to install.
Another item discussed was the fact that quite often through eastbound traffic
is trapped in the right lane as it approaches Cherokee Lane and is forced to
either violate the mandatory right turn sign or crowd into the left lane.
Through traffic could be permitted in both eastbound lanes if parking were re-
stricted on Kettleman east of Cherokee to the vicinity of the service station
driveways.

While this area always seems to have vehicles parked along here, the removal
of on -street parking would not appear to constitute a hardship on the local
merchants since adequate off-street parking is available. If the City will
restrict parking and paint the curb red, we will revise the signing and strip-
ing to acccoplish this change.
Not covered in your letter but requested by Rich durir 4 our meeting was acci-
dent data for Kettleman Lane between Ham Lane and Roue 99. Attached are two
lists of accident data for the time period 1-1-84/12-31-86; one is by highway
segment and the other by intersection. The segment list contains all of the
accidents, including intersection accidents; the intersection list contains
only those assigned to the individual intersections. If you have any
questions regarding these lists, please contact Bob Ikeda of my staff at
948-7209.
If you have any other questions, please call me at 948-7878.
