DATE: V� OCTOBER 20, 1998
RE: APPROVAL OF ENGINEERING PROPOSAL FOR THE 1998 SPEED ZONE
SURVEY IN ACCORDANCE WITH CALIFORNIA VEHICLE CODE
SECTION 40802
Attached for your consideration is an engineering proposal from Willdan Associates to
provide a City-wide engineering and traffic speed zone survey.
The City's current speed zone survey will expire in December, 1998. This survey is
required for radar enforcement of speed zones in accordance with California Vehicle Code
Section 40802. The survey will include 42 street segments in the City, excluding
Rosemead Boulevard, which was recently surveyed by the State of California. The
sections of De Adalena Street that Council requested be surveyed during the Budget Study
Session are included as well.
Due to the current construction on Valley Boulevard, the engineering and traffic surveys
for Valley Boulevard will be delayed until construction is complete. Mission Drive will also
be delayed since it is being used as an alternate route during the Valley Boulevard
construction. These two roadways will be included as an addendum to this report. The
addendum will include a letter summarizing the findings of the engineering and traffic
survey and the survey sheets for Valley Boulevard and Mission Drive.
The proposed traffic and engineering speed zone survey is currently programmed in the
City's Fiscal Year 1998-99 budget.

Subject: City-Wide Speed Zone Survey
Dear Mr. Tripepi:
The current City-Wide Engineering and Traffic Survey for the City of Rosemead will expire
in December 1998. This survey is required for radar enforcement of speed zones in
accordance with California Vehicle Code Section 40802. Funds were provided in the 1998-
1999 budget for a new engineering and traffic survey for 42 street segments in the City.
The survey will exclude Rosemead Boulevard, which was recently surveyed by the State
of California.
Due to the current construction on Valley Boulevard, the engineering and traffic surveys
for Valley Boulevard will be delayed until construction is complete. Mission Drive will also
be delayed since it is being used as an alternate route during the Valley Boulevard
construction. These two roadways will be included as an addendum to this report. The
addendum will include a letter summarizing the findings of the engineering and traffic
survey and the survey sheets for Valley Boulevard and Mission Drive.
The following engineering services will be included in the City-Wide Engineering and Traffic
in conformance with the California Vehicle Code provisions:
• Twenty-four hour directional machine traffic volume counts will be conducted to
obtain current daily traffic volumes on 42 street segments. These traffic volume
counts will be made on a typical weekday. This count information will also provide
a data base, which can be used in future traffic studies and surveys.
• Field radar speed data consisting of either a sample size of 100 vehicles or for a
total of 2 hours of measurements on each of 42 street segments will be gathered.
These measurements will include observation of at least 50 vehicles in each
direction. Our field tally sheets will include engineering calculations of the average
speed, 85th percentile speed, the 10-mile pace speed, and percent in pace.
• Preliminary survey sheets will then be developed for each street segment. Volumes
and speed data, as well as other pertinent engineering information, will be
summarized on these sheets. Information from the speed survey conducted in
1993 will be updated to reflect the current conditions.

• Speed measurements will be analyzed and a visual inspection and assessment of
each street segment will be conducted to determine conditions that are not readily
apparent to motorists. Additionally, for each street segment, accident records will
be reviewed and summarized for the most recent 3-year period. Accident rates for
each segment will be calculated, summarized on the survey sheets, and compared
with anticipated accident rates developed by the Los Angeles County Department
of Public Works. These data will be used to develop preliminary speed zoning
recommendations that reflect actual conditions on each street segment.
• Five draft copies of the engineering and traffic survey report will then be prepared
and delivered to the City for consideration. The report will document the
methodology and procedures used for the survey and will include a summary of
recommended speed limits, as well as the survey sheets for each roadway
segment. Following review by the City staff and upon receipt of a complete and
consolidated set of written comments, 15 bound copies of the final report will be
delivered to the City within 10-working days for City Council approval.
Willdan Associates will complete the work as outlined above, including submittal of the
draft copies of the report to the City within 6 weeks of receiving your approval to proceed
with this work. It is proposed that compensation for the work outlined above will be at a
fixed fee of $15,000, based on the following:
Breakdown of costs:
• Machine Traffic Counts $ 4,500.00
• Radar Surveys 6,500.00
• Site Inspection 1,500.00
• Report Preparation 2,500.00
TOTAL $15.000.00
