PRESENTATION
PRESENTATION BY REPRESENTATIVES OF THE LOS ANGELES COUNTY
SHERIFF'S DEPARTMENT, LOMITA STATION ON TRAFFIC STATISTICS FOR THE
CITY OF ROLLING HILLS.
Sgt. Osburn presented the monthly supplemental traffic enforcement statistics for the months of
January and February 2018. He noted that the month of March 2018 has not been completed yet. He
stated that there were a total of 19 moving violations for the month of January 2018. Sgt. Osbum
indicated that a moving violation occurred for speeding 51 miles per hour in the month of January
2018 by a non-resident. He reported that there were five moving violations that occurred in the month
of February 2018.
Discussion ensued concerning the option to attend traffic school by residents who are cited under the
Rolling Hills Municipal Code (RHMC).
In response to Commissioner Hawkins' inquiry, Sgt. Osburn stated that the hazardous citations issued
during the month of December 2017 were most likely lower due to residents being out of town for the
holiday season and less hours worked by the Sheriff's Deputies.
Traffic Engineer Munoz stated that the elevated number of 77 hazardous citations issued during the
month of November 2017 could be attributed to her request for targeted traffic enforcement prior to the
collection of the engineering and traffic survey data.
Discussion ensued concerning delivery service and postal vehicles speeding in the City.

OLD BUSINESS
UPDATE ON TRAFFIC CITATIONS ISSUED AGAINST THE CITY OF ROLLING HILLS
MUNICIPAL CODE (ORAL REPORT).
Interim City Manager Schwartz provided an update to the Traffic Commission on the matter of
allowing residents to attend traffic school when they receive a traffic citation under the RHMC. She
indicated that the City Council directed the City Attorney to conduct further research on the matter.
NEW BUSINESS
CONSIDERATION OF THE RESULTS OF THE 2018 CITY OF ROLLING HILLS
ENGINEERING AND TRAFFIC SURVEY.
Traffic Engineer Munoz presented a summary of the 2018 Engineering and Traffic (E&T) Survey and
staff report. She stated that the reason an E&T Survey is conducted is to provide the tools for the
Sherriff's Department to enforce the speed limits with radar; otherwise the Sheriff's Department would
not be able to enforce the speed limit. Traffic Engineer Munoz indicated that the California Vehicle
Code (CVC) requires an E&T Survey every five years to establish and re -certify posted speed limits
and to perform radar enforcement. She indicated that the E&T Survey can be extended to seven years,
or up to ten years, with certain provisions being met. Traffic Engineer Munoz stated that the E&T
Survey included the collection of radar speed data and traffic counts on the following street segments:
1. Crest Road West - west City limit to Portuguese Bend Road
2. Crest Road East - Portuguese Bend Road to Eastfield Drive
3. Eastfield Drive - Crest Road East to Chuckwagon Road
4. Eastfield Drive - Chuckwagon Road to Palos Verdes Drive East
5. Portuguese Bend Road - Crest Road E/W to Poppy Trail
6. Portuguese Bend Road - Poppy Trail to Saddleback Road
7. Saddleback Road - Poppy Trail to Portuguese Bend Road
8. Southfield Drive - Crest Road East to Packsaddle Road
Traffic Engineer Munoz stated that based on the E&T Survey she recommends that the speed limits
along the following six specified segments of roadway remain the same, based on traffic counts, speed
data, and the roadway conditions: 1) Crest Road West - west City limit to Portuguese Bend Road,
posted speed limit: 30 miles per hour (MPH), recommended speed limit: 30 MPH; 2) Crest Road East -
Portuguese Bend Road to Eastfield Drive, posted speed limit: 30 MPH, recommended speed limit: 30
MPH; 3) Eastfield Drive - Crest Road East to Chuckwagon Road, posted speed limit: 25 MPH,
recommended speed limit: 25 MPH; 4) Portuguese Bend Road - Crest Road East/West to Poppy Trail,
posted speed limit: 30 MPH, recommended speed limit: 30 MPH; 5) Portuguese Bend Road - Poppy
Trail to Saddleback Road, posted speed limit: 30 MPH, recommended speed limit: 30 MPH; and 6)
Southfield Drive - Crest Road East to Packsaddle Road, posted speed limit: 25 MPH; recommended
speed limit: 25 MPH.
Traffic Engineer Munoz stated that based on the E&T Survey she recommends changes in speed for
two specified segments of roadway. She stated that the two segments were reviewed and analyzed
multiple times during the preparation of the E&T Survey; therefore, the following two segments have
recommended speed changes: 1) Eastfield Drive - Chuckwagon Road to Palos Verdes Drive East,
posted speed limit: 25 MPH, recommended speed limit: 30 MPH; and 2) Saddleback Road - Poppy
Trail to Portuguese Bend Road, posted speed limit: 25 MPH, recommended speed limit: 30 MPH.
Discussion ensued concerning the use of pacing, the Sherriff's Department's inability to use radar
enforcement if the City maintains the speed limits at 25 MPH for the two recommended segments of
roadway, and the 10 year recertification process.
Commissioner Raine inquired whether the two street segments of Eastfield Drive and Saddleback
Road could be categorized as residential streets with a prima facie speed limit of 25 MPH.
In response to Commissioner Raine's inquiry, Traffic Engineer Munoz provided the definition of a
residential street as being no more than 40 feet wide with one lane in each direction, with a certain
amount of dwelling units. She stated, however; the exception is once the City started to radar a street,
it may be difficult to go back and stop using radar to certify the speed limits because she did not know
why those streets were added. She indicated that Willdan was not part of the process of adding the two
street segments. She stated that almost all of the streets in the City qualify for 25 MPH with the

exception of Crest Road and Portuguese Bend Road. Traffic Engineer Munoz indicated that the City
could remove the streets, however; the CVC is very clear that once an E&T Survey is used to
determine the speed that is how it needs to be defined. Traffic Engineer Munoz indicated that once the
City began using the survey, thc City took away the prima facie designation possibility.
Discussion ensued regarding the history of the street segments included in the E&T Survey.
After further discussion, Traffic Engineer Munoz was directed by the Traffic Commission to research
whether the two street segments of Eastfield Drive and Saddleback Road could be lowered to 25 MPH
and be supported by the CVC. She stated that the justification would be that these streets qualify as
residential segments and that is the reason for the 25 MPH speed limit.
Commissioner Raine moved that the Traffic Commission accept the Engineering and Traffic Survey's
recommendation that the speed limits along the following 6 specified segments of roadway remain the
same: 1) Crest Road West from West City limit to Portuguese Bend Road; 2) Crest Road East from
Portuguese Bend Road to Eastfield Drive; 3) Eastfield Drive from Crest Road East to Chuckwagon
Road; 4) Portuguese Bend Road from Crest Road E/W to Poppy Trail; 5) Portuguese Bend Road from
Poppy Trail to Saddleback Road; and 6) Southfield Drive from Crest Road East to Packsaddle Road.
Commissioner Hawkins seconded the motion, which carried without objection.
By consensus, the Traffic Commission directed staff to further research the following 2 specified
segments of roadway from the Engineering and Traffic Survey and report back to the Traffic
Commission: 1) Eastfield Drive from Chuckwagon Road to Palos Verdes Drive East; and 2)
Saddleback Road from Poppy Trail to Portuguese Bend Road.

MATTERS FROM MEMBERS OF THE TRAFFIC COMMISSION
DISCUSSION AND POSSIBLE DIRECTION PERTAINING TO TRAFFIC CITATIONS
ISSUED AGAINST THE CITY OF ROLLING HILLS MUNICIPAL CODE (ORAL REPORT).
Chairman Wilson introduced the item and stated that he has received inquiries from residents regarding
the application of the Rolling Hills Municipal Code (RHMC) versus the California Vehicle Code
(CVC). He stated that in the past, traffic violations were not available to insurance companies; however,
. insurance companies are now able to access the RHMC violations within the City. He stated that the
-1-
disadvantage of this is that residents cannot attend traffic school for RHMC violations and there is no
opportunity to remove violations from a driving record. He indicated that he wanted to discuss the
matter and determine what options exist for the City. Chairman Wilson stated he was not aware if
citations could be written to the CVC since the City's are private.
City Manager Cruz stated that in the past the insurance companies were not aware of when citations
were issued; however, the insurance companies are now using citation information to determine the risk
factor for rates and premiums. He explained the process to convert to the CVC, which would take a
majority of the Rolling Hills Community Association's Board of Directors to approve or a majority of
the property owners must petition the City with a request; thereafter, the City is required to hold a public
hearing on the matter.
Sgt. Osburn discussed the history of issuing juvenile citations and that they are now written against the
CVC, which allows the citations to be handled by the Torrance Court instead of the Van Nuys Probation
Department.
Discussion ensued concerning the application of the CVC, current traffic violation issues by. residents,
enforcement of traffic violations, the advantages and disadvantages of converting to the CVC, and the
option to attend traffic school; •F
Discussion ensued concerning the lack of enforcement of the RHMC section that prohibits parking on
the bridle trails. Commissioner Hawkins provided photographs of vehicles parked on the bridle trails on
various streets in the City.
Following discussion, the Traffic Commission by consensus directed Commissioner Hawkins to inquire
with the Rolling Hills Community Association Board of Directors regarding their position on converting
to the California Vehicle Code and report the results back to the Traffic Commission (Margeta absent).

Chairman Wilson discussed the Rolling Hills Municipal Code (RHMC) versus the California Vehicle
Code (CVC) pertaining to the issuance of traffic citations. He stated that it is a burden for the residents
because they cannot attend traffic school when they receive a traffic citation and this issue continues to
be brought up by residents. Chairman Wilson discussed the two procedures to change the RHMC,
which are to have a special election with a majority of the residents voting yes, or to receive the
Rolling Hills Community Association (RHCA) Board of Directors approval.
Commissioner Hawkins stated that the traffic citation matter was discussed at the RHCA Board of
Directors meeting. He indicated that there was no interest by the RHCA to convert to the CVC.
Discussion ensued regarding the issuance of traffic citations.
Chairman Wilson requested that Sgt. Osburn explore whether residents can go to traffic school and if
this is possible, what steps are necessary to make this change. There was consensus by the Traffic
Commission for Sgt. Osburn to research this matter.
Commissioner Hawkins discussed the parking issues at St. John Fisher Church in the City of Rancho
Palos Verdes (RPV). He provided photos of his parking concerns. He indicated that the City of RPV
appears not to be interested in installing "no stopping" signs on the north side of the street.
Commissioner Hawkins stated that the City of RPV did not install a parking lot on Portuguese Bend
Road South where hikers and pedestrians could park their vehicles. Commissioner Hawkins suggested
that the new City Manager continue to pressure the City of RPV to get these vehicles off the roadway.
Chairman Wilson stated that this matter was in the City of RPV's jurisdiction and that it occurs mostly
on the weekends. Chairman Wilson indicated that he discussed the option of parking along the k -rails
with Captain Beringer, who said that parking is allowed there as long as vehicles are not impeding
traffic. Chairman Wilson stated that he attends a monthly meeting with the four Mayors of the
Peninsula Cities and that he would bring up this matter with the Mayor of the City of RPV.
Sgt. Osburn indicated that he attends the City of RPV's Traffic Commission meetings and this is an
issue that has been discussed several times. He stated that the City of RPV has received pushback
from the church and residents regarding the limited parking. Sgt. Osburn noted that the City of RPV
recently painted the curb red.
Vice Chairwoman Virtue stated that she feels it is mostly hikers that are impacting the parking.

TO: HONORABLE CHAIR AND MEMBERS OF THE TRAFFIC COMMISSION
FROM YOLANTA SCHWARTZ, INTERIM CITY MANAGER
VANESSA MUNOZ, TRAFFIC ENGINEER
SUBJECT: CONSIDERATION OF THE RESULTS OF THE 2018 CITY OF .ROLLING
HILLS ENGINEERING AND TRAFFIC SURVEY.
DATE: MARCH 22, 2018
ATTACHMENT:
Engineering and Traffic Survey
The California Vehicle Code (CVC) requires an Engineering and Traffic (E&T) Survey every five
years to establish and re -certify posted speed limits and to perform radar enforcement. The surveys
can be extended to 7 years provided the City's police officer(s) have completed a 24 -hour radar
operator course [CVC 40802(c)(2)(B)(i)(I)]. Additionally, some surveys may be extended to 10
years if a traffic engineer certifies that no changes in roadway or traffic conditions have occurred
[CVC 40802 (c)(2)(B)(i)(II)]. These provisions assure that posted speed limits are kept reasonably
current. Rolling Hills' last E&T survey was in September 2011 and expires on September 2018.
At the City Council's direction, an E&T Survey commenced in early November 2017. It included
the collection of radar speed data and traffic counts on the following street segments:
1. Crest Road West - west City limit to Portuguese Bend Road
2. Crest Road East - Portuguese Bend Road to Eastfield Drive
3: Eastfield Drive - Crest Road East to Chuckwagon Road
4. Eastfield Drive - Chuckwagon Road to Palos Verdes Drive East
5. Portuguese Bend Road - Crest Road E/W to Poppy Trail
6. Portuguese Bend Road - Poppy Trail to Saddleback Road
7. Saddleback Road - Poppy Trail to Portuguese Bend Road
8. Southfield Drive - Crest Road East to Packsaddle Road
-1-
DISCUSSION
The Engineering and Traffic Survey was conducted by Willdan Engineering in accordance with
procedures established by the California Manual of Uniform Traffic Control Devices (CA
MUTCD). Data from the survey is used to determine if the City's existing posted speed limits on
arterial and collector streets need to be modified. Posted speed limits are established to protect the
public and provide law enforcement with a clearly understood method to identify and apprehend
violators of the basic speed law. The three (3) primary elements of a survey include the
consideration of prevailing speeds, collision history, and roadway characteristics not readily
apparent to motorists. The attached survey report includes the speed survey methodology,
applicable CVC provisions, recommendation and maps of speed limits and traffic volumes.
The E&T Survey recommends that the speed limits along the 6 specified segments of roadway
shown below remain the same, based on traffic counts, speed data, and the roadway conditions:

The E&T Survey recommends changes in speed for 2 specified segments of roadway. The two
segments were reviewed and analyzed multiple times during the preparation of the E&T Survey. A
first set of speed survey data was collected with the data resulting in an increase in speeds. To
verify the validity of the data a second set of speed survey data was collected for the two segments,
however prior to its collection additional enforcement was requested from the Sheriff's Department
for a period prior to the data collection being performed. Data was then collected the day after
enforcement was completed with no changes to the speed survey data, therefore the following two
segments have recommended speed changes:

Subject: 2018 Engineering and Traffic Survey
Dear Mr. Cruz:
As requested, Willdan has completed an Engineering and Traffic (E&T) Survey to justify
and update the posted speed limits along.8 street segments in the City of Rolling Hills.
These segments were last surveyed in 2011, and require an update to comply with the 7 -
year limitation set forth in the California Vehicle Code (CVC).
We are pleased to submit the enclosed Report that describes the E&T survey procedures
and contains recommendations for posted speed limits on the City's arterial and collector
street system. A summary of these recommendations is included in the Analysis.
Supporting documentation for each speed zone recommendation is provided in the
Appendices.
The Report was conducted in accordance with applicable provisions of the CVC, following
procedures outlined in the California Manual on Uniform Traffic Control Devices (California
MUTCD) dated April 2017, and as required by Section 627 of the CVC. The Report is
intended to satisfy the requirements of Section 40802 of the CVC to enable the continued
use of radar for traffic speed enforcement.
We appreciate the opportunity to serve the City of Rolling Hills and the assistance and
cooperation afforded to us during the course of this study.
Very truly yours,
WILLDAN

INTRODUCTION
This Engineering and Traffic (E&T) Survey is intended to be the basis for the
establishment, revision, and enforcement of speed limits for selected streets within the City
of Rolling Hills. This E&T Survey presents recommended speed limits for 8 street
segments in the City of Rolling Hills. E&T Surveys are required by the State of California to
establish intermediate speed limits on local streets and to enforce those limits using radar
or other speed measuring devices. These surveys must be updated every 5 or 7 years to
ensure the speeds reflect current conditions as dictated by the California Vehicle Code
(CVC). The CVC also requires that the surveys be conducted based on the methodology
required by The California Manual on Uniform Traffic Control Devices (California MUTCD)
dated April 2017.
The survey was requested by the City for the proper posting of speed limits and to enable
the Sheriffs Department to utilize radar or other electronic speed measuring devices for
speed enforcement. CVC Sections 40801 and 40802 require E&T Surveys that verify the
prima facie speed limit before enforcement by such a device is legal. The law further
specifies that these surveys be conducted every 5 years. The surveys can be extended to
7 years provided the City's police officer(s) have completed a 24 -hour radar operator
course [CVC 40802(c)(2)(B)(i)(I)]. Additionally, some surveys may be extended to 10 years
if a traffic engineer certifies that no changes in roadway or traffic conditions have occurred
[CVC 40802 (c)(2)(B)(i)(II)]. These provisions assure that posted speed limits are kept
reasonably current.
The E&T Surveys for the City were conducted in accordance with procedures outlined in
the California MUTCD dated April 2017 and as required by Section 627 of the CVC. The
Code further describes three elements of an engineering and traffic survey:
1. Measurement of prevailing speed;
2. Accident history; and
3. Roadway characteristics not readily apparent to the motorist.
Posted speed limits are established primarily to protect the general public from the reckless
and unpredictable behavior of dangerous drivers. They provide law enforcement with a
clearly understood method to identify and apprehend violators of the basic speed law (CVC
Section 22350). This law states that "No person shall drive a vehicle on a highway at a
speed greater than is reasonable or prudent having due regard for weather, visibility, the
traffic on, and the surface and width of the highway, and in no event at a speed which
endangers the safety of persons or property." The posted speed limit gives motorists a
clear warning of the basic speed that is reasonable and prudent under typical driving
conditions.
2018 Engineering and Traffic Survey
1 City of Rolling Hills
The basic fundamentals for establishing speed limits recognize that the majority of drivers
behave in a safe and reasonable manner, and therefore, the normally careful and
competent actions of a reasonable driver should be considered legal. Speed limits
established on these fundamentals conform to the consensus that those who drive the
highway determine what speed is reasonable and safe, not on the judgment of one or a
few individuals. A radar speed study is usually used to record the prevailing speed of
reasonable drivers.
Speed limits are also established to advise drivers of conditions which may not be readily
apparent to a reasonable driver. For this reason, accident history, roadway conditions,
traffic characteristics, and land use must also be analyzed before determining speed limits.
Speed limit changes are usually made in coordination with physical changes in roadway
conditions or roadside developments. Unusually short zones of less than one-half mile in
length should be avoided to reduce driver confusion.
Additionally, it is generally accepted that speed limits cannot be successfully enforced
without voluntary compliance by a majority of drivers. Consequently, only the driver whose
behavior is clearly out of line with the normal flow of traffic is usually targeted for
enforcement.
ELEMENTS OF THE ENGINEERING AND TRAFFIC SURVEY
The California MUTCD dated April 2017 specifies the methodology to be used for
completing E&T Surveys. This methodology includes an evaluation of current vehicle
speeds, accident history and conditions not readily apparent to motorists. The basic
elements of the Engineering and Traffic Survey are discussed in more detail as follows:
Speed Sampling
Existing vehicle speeds are surveyed by a certified radar operator with a calibrated radar
unit in an unmarked vehicle. Speed samples are taken for each segment representing a
statistically significant sample of current traffic. This data is then evaluated to identify the
distribution of speeds. A key element in the evaluation is the identification of the 85th
percentile speed. The 85th percentile speed is the speed at or below which 85 percent of
the traffic travels. This threshold represents what is historically found to be a safe and
reasonable speed for most drivers based on common roadway conditions. Therefore, a
speed limit is established at the nearest 5 -mile per hour (mph) increment to the 85th
percentile speed, except as shown in the two options below.
Options:
1. The posted speed may be reduced by 5 mph from the nearest 5 mph increment of
the 85th -percentile speed, in compliance with CVC Section 627 and 22358.5.
2. For cases in which the nearest 5 mph increment of the 85th -percentile speed would
require a rounding up, then the speed limit may be rounded down to the nearest 5
mph increment below the 85th percentile speed, if no further reduction is used.
Refer to CVC Section 21400(b).
2018 Engineering and Traffic Survey
2 City of Rolling Hills
If the speed limit to be posted has had the 5 -mph reduction applied, then an E&T Survey
shall document in writing the conditions and justification for the lower speed limit. The
reasons for the,lower speed limit shall be in compliance with CVC Section 627 and 22358.5
The following examples are provided to explain the application of these speed limit criteria:
A. Using Option 1 above and first step is to round down: If the 85th percentile speed in
a speed survey for ;a location was 37 mph, then the speed limit would be
established at 35 mph since it is the closest 5 mph increment to the 37 mph speed.
As indicated by the option, this 35 mph established speed limit could be reduced by
5 mph to 30 mph if conditions and justification for using this lower speed limit are
documented in the E&T Survey.
B. Using Option 1 above and first step is to round up: If the 85th percentile speed in a
speed survey for a location was 33 mph, then the speed limit would be established
at 35 mph since it is the closest 5 mph increment to the 33 mph speed. As
indicated by the option, this 35 mph speed limit could be reduced by 5 mph to 30
mph if the conditions and justification for using this lower speed limit are
documented in the E&T Survey.
C. Using Option 2 above and first step is to round up: If the 85th percentile speed in a
speed survey for a location was 33 mph, instead of rounding up to 35 mph, the
speed limit can be established at 30 mph, but no further reduction can be applied.
Collision History
Reported collisions are reviewed for each street segment to determine if there is a higher
than average rate of collisions. A segment that has an above -average collision rate
typically suggests conditions that are not readily apparent to motorists.
A summary of the collision rates for the 8 surveyed street segments is provided in Table 2.
Conditions Not Readily Apparent To Motorists
Each street segment is field inspected to identify roadway conditions that may not be
readily apparent to motorists. A determination is made whether any conditions are
significant and warrant the recommendation of the speed limit 5 mph or more below the
basic speed limit. It is important to note that the California MUTCD dated April 2017
recommends exercising great care when establishing speed limits 5 mph or more below
the basic speed limit.

SURVEY CONDITIONS
SURVEY LOCATIONS
The procedures described below describe the criteria and methods used to survey selected
streets within the City of Rolling Hills. The specific location of the radar speed survey for
each street segmentywas selected after considering the following:
1. Minimum stop sign and traffic signal influence.
2. Minimum visibility restrictions.
3. Non -congested traffic flow away from intersections and driveways.
4. Minimum influence from curves or other roadway conditions that would affect
the normal operation of a vehicle.
DATA COLLECTION
Data of existing conditions was obtained including prevailing speed of vehicles, traffic
collisions, visibility restrictions, and roadway conditions within the community. Speed data
and field reviews were conducted at 8 locations during the month of November 2017.
Speed Data
Radar speed measurements were conducted at 8 locations during the month of November
2017. The radar speed distribution forms -are in Appendix B. All surveys were conducted
in good weather conditions, during off-peak hours on weekdays. The radar unit was
operated from an unmarked vehicle to minimize any influence on driver behavior.
Typically, a minimum sample size of 100 vehicles or the total samples during a maximum
period of 2 hours were obtained for each segment. Traffic speeds in both directions were
recorded for individual segments.

Collision Data
Collision data was obtained from Los Angeles County's Sheriff's Department's Collision
Summary Report. For this study, collision data was used from the latest 4 years of reported
accidents from January 1, 2013 to December 31, 2016. The collision rates for the 8
segments are expressed in accidents per million vehicle miles (A/MVM). To calculate these
rates, 24 -hour traffic volumes were collected for each street segment. This information was
then entered into the following formula to determine the collision rate:
R =
Ax1,000,000
tx365 days xixv
year
A = Number of midblock collisions over time period
R = Collision Rate (accidents/million vehicle miles)
t = Time Period Covered (in years)
/ = Length of Segment (miles)
v = Traffic Volume (average daily traffic)
The segment collision rate was then compared to the average statewide collision rate. The
average statewide collision rates were obtained from 2014 Collision Data on California
State Highways published by Caltrans.
Field Review Data
A field review was conducted for each of the selected street segments in the City with
consideration for the following factors:
1. Street width and alignment (design speed);
2. Pedestrian activity and traffic flow characteristics;
3. Number of lanes and other channelization and striping patterns;
4. Frequency of intersections, driveways, and on -street parking;
5. Location of stop signs and other regulatory traffic control devices;
6. Visibility obstructions;
7. Land use and proximity to schools;
8. Pedestrian and bicycle usage;
9. Uniformity with existing speed zones and those in adjacent jurisdictions; and
10. Any other unusual condition not readily apparent to the driver.

ANALYSIS
CRITERIA
Survey data was compiled and analyzed to determine the recommended speed limit in
accordance with several criteria contained in the California MUTCD dated April 2017.
Some of the criteria used are:
A. The critical speed or 85th percentile speed is that speed at or below which 85
percent of the traffic is moving. This speed is the baseline value in determining
what the majority of drivers believe is safe and reasonable. Speed limits set higher
than the critical speed are not considered reasonable and safe. Speed limits set
lower than the critical speed make a large number of reasonable drivers "unlawful,"
and do not facilitate the orderly flow of traffic. The "basic speed limit" is the nearest
5 mph increment to the 85th percentile speed.
B. The 10 mile per hour (mph) pace speed is the 10 mph increment that contains the
highest percentage of vehicles. It is a measure of the dispersion of speeds across
the range of the samples surveyed. An accepted practice is to keep the speed limit
within the 10 mph pace while considering the critical speed and other factors that
might require a speed lower than the critical speed.
C. The collision rate for each street segment is compared to average collision rates
that can be reasonably expected to occur on streets and highways in other
jurisdictions, in proportion to the volume of traffic per lane mile. These average
collision rates have been developed by the State of California and are considered
reasonable for use in the City of Rolling Hills.
RESULTS AND RECOMMENDATIONS
The E&T Survey Forms, presented in Appendix A, illustrate results of a thorough
evaluation of the available data and recommend a speed limit for each street segment
surveyed. A complete summary of all recommendations is shown in Table 2. In each
case, the recommended speed limit was consistent with the .prevailing behavior as
demonstrated by the radar speed measurements. Typically, a speed limit in the upper
range of the 10 -mile pace was selected unless a collision rate significantly higher than
expected was discovered or roadway conditions not readily apparent to the driver were
identified. Any segments with recommended speed limits 5 mph or more below the basic
speed limit are fully explained later in this report.
The Legislature, in adopting Section 22358.5 of the CVC, has made it clear that physical
conditions, such as width, curvature, grade and surface conditions, or any other condition
readily apparent to a driver, in the absence of other factors, would not be the basis for
special downward speed zoning. In these cases, the basic speed law (CVC Section
22350) is sufficient to regulate such conditions.
The recommendations contained in this Report are intended to establish prima facie speed
limits. They are not intended to be absolute for all prevailing conditions. All prima facie
2018 Engineering and Traffic Survey
6 City of Rolling Hills
speed violations are actually violations of the basic speed law (CVC Section 22350). This
statute states that a person shall not drive a vehicle at a speed greater than is safe having
regard for traffic, roadway, and weather conditions. A prima facie limit is intended to
establish a maximum safe speed under normal conditions.
Table 1 identifies the street segments with recommended changes in posted speed limits
and Table 2 summarizes the recommendations for all surveyed segments.

SEGMENTS WITH SPECIAL CONDITIONS
The following segments surveyed had recommended speed limits that were 5 miles per
hour (mph) or more below the critical speed due to conditions not readily apparent to the
driver. Each segment is discussed below.
Segment #1 — Crest Road West — West City Limit to Portuguese Bend Road
This segment is currently posted at 30 mph and has 1 through lane in each direction with
an ADT of 1,938 vehicles per day. The adjacent land use is rural residential and
equestrian nature in a flat to rolling terrain. The critical speed is 37 mph and would
normally justify a 35 mph posted speed limit. However, due to vertical and horizontal
curves, various hidden driveways, and equestrian traffic that may not be apparent to
unfamiliar drivers, a lower speed limit is prudent. It is recommended that the speed limit
remain at 30 mph for the above reasons.
Segment #2 — Crest Road East —Portuguese Bend Road to Eastfield Drive
This segment is currently posted at 30 mph and has 1 through lane in each direction with
an ADT of 1,825 vehicles per day. The adjacent land use is rural residential and
equestrian nature in a flat to rolling terrain. The critical speed is 37 mph and would
normally justify a 35 mph posted speed limit. However, due to vertical and" horizontal
curves, various hidden driveways, and equestrian traffic that may not be apparent to
unfamiliar drivers, a lower speed limit is prudent. It is recommended that the speed limit
remain at 30 mph for the above reasons.
Segment #3 — Eastfield Drive — Crest Road to Chuckwagon Road
This segment is currently posted at 25 mph and has 1 through lane in each direction with
an ADT of 1,008 vehicles per day. The adjacent land use is rural residential and
equestrian in a mountainous terrain. The critical speed is 32 mph and would normally
justify a 30 mph posted speed limit. However, due to vertical .and horizontal curves,
various hidden driveways, and equestrian traffic that may not be apparent to unfamiliar
drivers, a lower speed limit is prudent. It is recommended that the speed limit remain at 25
mph for the above reasons.
Segment #5 — Portuguese Bend Road — Crest Road E/W to Poppy Trail
This segment is currently posted at 30 mph and has 1 through lane in each direction with
an ADT of 1,728 vehicles per day. The adjacent land use is rural residential and
equestrian nature in a mountainous terrain. The critical speed is 35 mph and would
normally justify a 35 mph posted speed limit. However, due to vertical and horizontal
curves, various hidden driveways, and equestrian traffic that may not be apparent to
unfamiliar drivers, a lower speed limit is prudent. It is recommended that the speed limit
remain at 30 mph for the above reasons.

Segment #6 — Portuguese Bend Road — Poppy Trail to Saddleback Road
This segment is currently posted at 30 mph and has 1 through lane in each direction with
an ADT of 1,978 vehicles per day. The adjacent land use is rural residential and
equestrian nature in a mountainous terrain. The critical speed is 36 mph and would
normally justify a 35 mph posted speed limit. However, due to vertical and horizontal

Prevailing speeds as determined by traffic engineering measurements.
Accident records.
Highway, traffic, and roadside conditions not readily apparent to the driver.
(c) When conducting an engineering and traffic survey,' local authorities, in addition to the
factors set forth in paragraphs (1) to (3), inclusive, of subdivision (b) may consider all of the
following:
(1) Residential density, if any of the following conditions exist on the particular portion of
highway and the property contiguous thereto, other than a business district:
a. Upon one side of the highway, within a distance of a quarter of a mile, the
contiguous property fronting thereon is occupied by 13 or more separate
dwelling houses of business structures.
b. Upon both sides of the highway, collectively, within a distance of a quarter of
a mile, the contiguous property fronting thereon is occupied by 16 or more
separate dwelling houses or business structures.
c. The portion of highway is longer than one -quarter of a mile but has the ratio
of separate dwelling houses or business structures to the length of the
highway described in either subparagraph (A) or (B).
(2) Pedestrian and bicyclist safety.
Section 21400.
(b) The Department of Transportation shall revise the California Manual on Uniform Traffic
Control Devices, as it read on January 1, 2012, to require the Department of Transportation
or a local authority to round speed limits to the nearest five miles per hour of the 85th
percentile of the free -flowing traffic. However, in cases in which the speed limit needs to be
rounded up to the nearest five miles per hour increment of the 85th -percentile speed, the
Department of Transportation or a local authority may decide to instead round down the
speed limit to the lower five miles per hour increment, but then the Department of
Transportation or a local authority shall not reduce the speed limit any further for any reason.
Basic Speed Law
22350. No person shall drive a vehicle upon a highway at a speed greater than is reasonable or
prudent having due regard for weather, visibility, the traffic on, and the surface and width of, the
highway, and in no event at a speed which endangers the safety of persons or property.

Speed Law Violations
Section 22351.
(a) The speed of any vehicle upon a highway not in excess of the limits specified in Section
22352 or established as authorized in this code is lawful unless clearly proved to be in
violation of the basic speed law.
(b) The speed of any vehicle upon a highway in excess of the prima facie speed limits in Section
22352 or established as authorized in this code is prima facie unlawful unless the defendant
establishes by competent evidence that the speed in excess of said limits did not constitute a
violation of the basic speed law at the time, place and under the conditions then existing.
Prima Facie Speed Limits
Section 22352.
The prima facie limits are as follows and shall be applicable unless changed as authorized in this
code and, if so changed, only when signs have been erected giving notice thereof:
(a) Fifteen miles per hour:
(1) When traversing a railway grade crossing, if during the last 100 feet of the
approach to the crossing the driver does not have a clear and unobstructed view of
the crossing and of any traffic on the railway for a distance of 400 feet in both
directions along such railway. This subdivision does not apply in the case of any
railway grade crossing where a human flagman is on duty or a clearly visible
electrical or mechanical railway crossing signal device is installed but does not then
indicate the immediate approach of a railway train or car.
(2) When traversing any intersection of highways, if during the last 100 feet of the
driver's approach to the intersection, the driver does not have a clear and
unobstructed view of the intersection and of any traffic upon all of the highways
entering the intersection for a distance of 100 feet along all those highways, except at
an intersection protected by stop signs or yield right-of-way signs or controlled by
official traffic control signals.
(3) On any alley.
(b) Twenty-five miles per hour:
(1) On any highway other than a state highway, in any business or residence district
unless a different speed is determined by local authority under procedures set forth in
this code.
(2) When approaching or passing a school building or the grounds thereof,
contiguous to a highway and posted with a standard "SCHOOL" warning sign, while
children are going to or leaving the school either during school hours or during the •
noon recess period. The prima facie limit shall also apply when approaching or
passing any school grounds which are not separated from the highway by a fence,
gate or other physical barrier while the grounds are in use by children and the
highway is posted with a standard "SCHOOL" warning sign. For purposes of this
subparagraph, standard "SCHOOL" warning signs may be placed at any distance up
to 500 feet away from school grounds.
2018 Engineering and Traffic Survey
13 City of Rolling Hills
(3) When passing a senior center or other facility primarily used by senior citizens,
contiguous to a street other than a state highway and posted with a standard
"SENIOR" warning sign. A local authority may erect a sign pursuant to this paragraph
when the local agency makes a determination that the proposed signing should be
implemented. A local authority may request grant funding from the Pedestrian Safety
Account pursuant to Section 894.7 of the Streets and Highways Code, or any other
grant funding available to it, and use that grant funding to pay for the erection of
those signs, or may utilize any other funds available to it to pay for the erection of
those signs, including, but not limited to, donations from private sources.
Increase of Local Speed Limits to 65 Miles Per Hour
Section 22357.
(a) Whenever a local authority determines upon the basis of an engineering and traffic survey
that a speed greater than 25 miles per hour would facilitate the orderly movement of
vehicular traffic and would be reasonable and safe upon any street other than a state
highway otherwise subject to a prima facie limit of 25 miles per hour, the local authority may
by ordinance determine and declare a prima facie speed limit of 30, 35, 40, 45, 50, 55 or 60
miles per hour or a maximum speed limit of 65 miles per hour, whichever is found most
appropriate to facilitate the orderly movement of traffic and is reasonable and safe. The
declared prima facie or maximum speed limit shall be effective when appropriate signs
giving notice thereof are erected upon the street and shall not thereafter be revised except
upon the basis of an engineering and traffic survey. This section does not apply to any 25
mile per hour prima facie limit, which is applicable when passing a school building or the
grounds thereof or when passing a senior center or other facility primarily used by senior
citizens.
(b) This section shall become operative on the date specified in subdivision (c) of Section
22366.
Downward Speed Zoning
Section 22358.5.
It is the intent of the Legislature that physical conditions such as width, curvature, grade and surface
conditions, or any other condition readily apparent to a driver, in the absence of other factors, would
not require special downward speed zoning, as the basic rule of Section 22350 is sufficient
regulation as to such conditions.
Boundary Line Streets
Section 22359.
With respect to boundary line streets and highways where portions thereof are within different
jurisdictions, no ordinance adopted under Sections 22357 and 22358 shall be effective as to any
such portion until all authorities having jurisdiction of the portions of the street concerned have
approved the same. This section shall not apply in the case of boundary line streets consisting of
separate roadways within different jurisdictions.
Speed Trap Prohibition
Section 40801.
2018 Engineering and Traffic Survey
14 City of Rolling Hills
No peace officer or other person shall use a speedtrap in arresting, or participating or assisting in
the arrest of, any person for any alleged violation of this code nor shall any speed trap be used in
securing evidence as to the speed of any vehicle for the purpose of an arrest or prosecution under
this code.
Speed Trap
Section 40802.
(a) A "speed trap" is either of the following:
(1) A particular section of a highway measured as to distance and with boundaries
marked, designated, or otherwise determined in order that the speed of a vehicle
may be calculated by securing the time it takes the vehicle to travel the known
distance.
(2) A particular section of a highway with a prima facie speed limit that is provided by this
code or by local ordinance under subparagraph (A) of paragraph (2) of subdivision
(a) of Section 22352, or established under Section 22354, 22357, 22358, or 22358.3,
if that prima facie speed limit is not justified by an engineering and traffic survey
conducted within five years prior to the date of the alleged violation, and enforcement
of the speed limit involves the use of radar or any other electronic device that
measures the speed of moving object. This paragraph does not apply to a local
street, road, or school zone.
(b)(1) For purposes of this section, a local street or road is one that is functionally classified as
"local" on the "California Road System Maps," that are approved by the Federal Highway
Administration and maintained by the Department of Transportation. When a street or road
does not appear on the "California Road System Maps," it may be defined as a "local street
or road" if it primarily provides access to abutting residential property and meets the following
three conditions:
(A) Roadway width of not more than 40 feet.
(B) Not more than one-half of a mile of uninterrupted length. Interruptions shall include
official traffic control signals as defined in Section 445.
(C) Not more than one traffic lane in each direction.
(2) For purposes of this section "school zone" means that area approaching or passing a school
building or the grounds thereof that is contiguous to a highway and on which is posted a
standard "SCHOOL" warning sign, while children are going to or leaving the school either
during school hours or during the noon recess period. "School zone" also includes the area
approaching or passing any school grounds that are not separated from the highway by a
fence, gate, or other physical barrier while the grounds are in use by children if that highway
is posted with a standard "SCHOOL" warning sign.
(c)(1) When all the following criteria are met, paragraph (2) of this subdivision shall be applicable
and subdivision (a) shall not be applicable:
(A) When radar is used, the arresting officer has successfully completed a radar operator
course of not less than 24 hours on the use of police traffic radar, and the course
was approved and certified by the Commission on Peace Officer Standards and
Training.
2018 Engineering and Traffic Survey
15 City of Rolling Hills
(B) When laser or any other electronic device is used to measure the speed of moving
objects, the arresting officer has successfully completed the training required in
subparagraph (A) and an additional training course of not less than two hours
approved and certified by the Commission on Peace Officer Standards and Training.
(C)(i) The prosecution proved that the arresting officer complied with subparagraphs (A)
and (B) and that an engineering and traffic survey has been conducted in
accordance with subparagraph (B) of paragraph (2). The prosecution proved that,
prior to the officer issuing the notice to appear, the arresting officer established that
the radar, laser, or other electronic device conformed to the requirements of
subparagraph (D).
(ii) The prosecution proved the speed of the accused was unsafe for the conditions
present at the time of alleged violation unless the citation was for a violation of
Section 22349, 22356, or 22406.
(D) 'The radar, laser, or other electronic device used to measure the speed of the
accused meets or exceeds the minimal operational standards of the National Traffic
Highway Safety Administration, and has been calibrated within the three years prior
to the date of the alleged violation by an independent certified laser or radar repair
and testing or calibration facility.
(2) A "speed trap" is either of the following:
(A) A particular section of a highway measured as to distance and with boundaries
marked, designated, or otherwise determined in order that the speed of a vehicle
may be calculated by securing the time it takes the vehicle to travel the known
distance.
(B)(i) A particular section of a highway or state highway with a prima facie speed limit that
is provided by this code or by local ordinance under subparagraph (A) of paragraph
(2) of subdivision (a) of Section 22352, or established under Section 22354, 22357,
22358, or 22358.3, if that prima facie speed limit is not justified by an engineering
and traffic survey conducted within one of the following time periods, prior to the date.
of the alleged violation, and enforcement of speed limit involves the use of radar or
any other electronic device that measures the speed of moving objects:
(1) Except as specified in subclause (II), seven years.
(II) If an engineering and traffic survey was conducted more than seven years
prior to the date of the alleged violation, and a registered engineer evaluates
the section of the highway and determines that no significant changes in
roadway or traffic conditions have occurred including, but not limited to,
changes in adjoining property or land use, roadway width, or traffic volume,
10 years.
(ii) This subparagraph does not apply to a local street, road, or school zone.
Speed Trap Evidence
Section 40803.
(a) No evidence as to the speed of a vehicle upon a highway shall be admitted in any court upon
the trial of any person in any prosecution under this code upon a charge involving the speed
2018 Engineering and Traffic Survey
16 City of Rolling Hills
of a vehicle when the evidence is based upon or obtained from or by the maintenance or use
of a speed trap.
(b) In any prosecution under this code of a charge involving the speed of a vehicle, where
enforcement involves the use of radar or other electronic devices which measure the speed
of moving objects, the prosecution shall establish, as part of its prima facie case, that the
evidence or testimony presented is not based upon a speed trap as defined in paragraph (2)
of subdivision (a) of Section 40802.
(c) When a traffic and engineering survey is required pursuant to paragraph (2) of subdivision
(a) of Section 40802, evidence that a traffic and engineering survey has been conducted
within five years of the date of the alleged violation or evidence that the offense was
committed on a local street or road as defined in paragraph (2) of subdivision (a) of Section
40802 shall constitute a prima facie case that the evidence or testimony is not based upon a
speed trap as defined in paragraph (2) subdivision (a) of Section 40802.

SPEED DETERMINATION
The basic fundamentals for
establishing speed limits
recognize that the majority
of drivers behave in a safe
and reasonable manner.
The 85th percentile
speed is the speed at
or below which 85
percent of the traffic
travels.

ENGINEERING
SPEED DETERMINATION
A "basic speed limit" is
established at the nearest
5 -mile per hour (mph)
increment to the 85th
percentile speed.
If the 85th percentile
speed is 33 mph, the
basic speed limit is
3 5 mph. (Option 1)
If the 85th percentile
speed is 32 mph, the
basic speed limit is
30 mph. (Option 1)
