Exhibit Change Effect
C One Way on Oak Making Walnut one way eastbound eliminates the
b Walnut need for a left turn pocket on Ham Lane.
Total traffic on Ham increases north of Walnut.
Overall results would be similar to installing
a left turn barrier at Walnut (Exhibit B).
D Open Pacific Ave. Total traffic south of Walnut drops by 12% dur-
to Lodi Ave. for ing this hour. Northbound to westbound left
right turns only turns at Lodi increase significantly.
E Open Pacific Ave. Net effect essentially the same as Exhibit D
to Lodi Ave. for since bulk of left turns were assigned to
right turns only Pacific Ave.
AND Barrier at
Walnut
Of the above schemes, only Exhibits D and E show any reduction in Ham Lane Traffic.
However, the reduction is minor and is based on the assumption that the maximum
possible number of drivers will use Pacific Avenue rather than Ham Lane. On a
total daily traffic bssis and, more importantly, P.M. peak basis (after .school is
out) the overall effect is insignificant.
PARKING ANALYSIS: Exhibits F and G show schematics of various striping alte me-;Ves
or ►,idening Alternates B. B-1 and C.1 Exhibit H summarizes the effects of the
striping alternatives on parking. Some points to note are:
o Alterrate B provides the most on -street parking and does the best Job of
acconmodating traffic.
o Eliminating the northbound to westbound left turn lane at Walnut releases up
to eight stalls from either "No" or "Restricted" parking. (Compare B -la
to b and d.)
o Striping options B -la. B -lb, B -lc and B -Id do not meet City's lane width
standards for a major collector street, tFWefore they can not be
recommended by staff.
o "Restricted Parking" would be needed during the hours of 10 a.m, to 6 p.m.
and could be an enforcement problem.
1 Alternate B widens on the west side and partially on the east side south of Walnut
to provide a minimum of 56 feet curb to curb.
Alternate B -I widens only on the west side and provides 50 feet curb to curb minimum.
Alternate C widens only on the west side south of Walnut and provides 44 feet curb
to curb minimum.

RECOMMENDATION: Staff has previously recommended Alternate B-1 as the project
which s most cost effective and will handle projected traffic through most of
the life of the project.
Establishing "No left turns" onto Walnut and/or extending Pacific Avenue to
Lodi will not improve safety or change the long term need for widening Ham Lane.
If the Council feels strongly about retaining on -street parking, then Alternate B
is recommended with the comment that for an additional S93,000 the full project
(64 feet curb to curb) could be constructed. If Council is more concerned about
parking than the effect of widening, serious consideration should be given to
the full widenin

PUBLIC WORKS DEPARTMENT
TO: City Council
FROM: City Manager
DATE: December 13, 1984
SUBJECT: Ham Lane Improvement Project
COUNCIL COMMUNICATION
BACKGROUND INFORMATION: At the City Council's request, additional analysis has
been done on the Ham Lane project with the goal of maximizing on -street parking.
Specifically, staff was asked to look at prohibiting northbound to westbound left
turns at Walnut, making Oak and Walnut west of Ham into a one-way couplet and
extending Pacific Avenue to Lodi Avenue with right turn access only. In addition,
the concept of "Restricted Parking", i.e. no parking during certain hours has been
evaluated.
TRAFFIC ANALYSIS: The specific measures mentioned above all have to do with
reducing the impact of Lodi High School traffic on Ham Lane traffic. Therefore
one hour turn counts were taken at the time school was dismissed (2:30 p.m.).
This information combined with previous counts is shown on a traffic flow map,
Exhibit A. The following is evident from the flow map:
1. Of the 240 vehicles that travel east on Oak and Walnut, the majority
turn right (Southbound - 60 from Oak, 130 from Walnut), but relatively
few turn right (Westbound onto Lodi Avenue - less than 60).
2. The highest, one direction volume is southbound between Walnut and
'_od i (730 vph) .
3. Volumes on Ham Lane are comparable to those on Lodi Avenue.
The remainder of the High School traffic uses Pacific Avenue at Elm Street_ The
counts are in general agreement with the student traffic as reported by the school.
Exhibits B, C, D and E show the expected effect of various changes described below.
The new volumes are shown next to the crossed -out figures for ease of comparison.
Exhibit Change Effect
B Barrier @ Walnut A permanent rai5�d barrier at Walnut would eliminate
the need for a left turn pocket on Nam Lane.
Traffic increases on Ham north of Walnut
