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. -1- 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 Minutes 03-22-18 Traffic Commission Meeting -2- 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).

Date: 03/22/18 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: Segment Posted Speed Limit Recommended Speed Limit Crest Road West - west City limit to Portuguese Bend Road 30 30 Crest Road East - Portuguese Bend Road to Eastfield Drive 30 30 Eastfield Drive - Crest Road East to Chuckwagon Road 25 25 Portuguese Bend Road - Crest Road E/W to Poppy Trail 30 30 Portuguese Bend Road - Poppy Trail to Saddleback Road 30 30 Southfield Drive - Crest Road East to Packsaddle Road 25 25 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: Segment Posted Speed Limit Recommended Speed Limit Eastfield Drive - Chuckwagon Road to Palos Verdes Drive East 25 30 Saddleback Road - Poppy Trail to Portuguese Bend Road 25 30 -2- 03-22-18 TC SR RECOMMENDATION The Traffic Commission's review, comment and recommendation to the City Council on the draft E&T Study report is requested. With the Traffic Commission's input, the report will be forwarded in final form to the City Council for consideration and decision.

Cruz City Manager City of Rolling Hills No. 2 Portuguese Bend Road Rolling Hills, CA 90274 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.

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. 3 2018 Engineering and Traffic Survey — City of Rolling Hills 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. r 2018 Engineering and Traffic Survey 4 City of Rolling Hills 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. 2018 Engineering and Traffic Survey 5 City of Rolling Hills 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. 2018 Engineering and Traffic Survey • 7 City of Rolling Hills T aS4 M 5 '4.

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. 2018 Engineering and Traffic Survey 10 City of Rolling Hills 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 curves, varioushidden 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. 2018 Engineering and Traffic Survey 11 City of Rolling Hills LEGISLATIVE REFERENCES APPLICABLE SECTIONS OF CALIFORNIA VEHICLE CODE SECTION 1. Section 627 of the Vehicle Code: Section 627. (a) "Engineering and traffic survey,"as used in this code, means a survey of highway and traffic conditions in accordance with methods determined by the Department of Transportation for use by state and local authorities. (b) An engineering and traffic survey shall include, among other requirements deemed necessary by the department, consideration of all of the following: (1) (2) (3) 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. 2018 Engineering and Traffic Survey 12 City of Rolling Hills 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.

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.

(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. 2018 Engineering and Traffic Survey 17 City, of Rolling Hills APPENDIX A Street Segment Data 2018 Engineering and Traffic Survey City of Rolling Hills CITY OF ROLLING HILLS • ENGINEERING AND TRAFFIC SURVEY STREET Crest Road West FROM West City Limit CERTIFICATION DATE TO Portuguese Bend Road 1 SPEED FACTORS Date of Speed Survey Time of Speed Survey 50th Percentile Speed (Mean Speed) 85th Percentile Speed Average Speed 10 mph Pace Speed Percentage of Vehicles in Pace Number of Survey Samples 11/8/2017 10:25AM 32 mph. 37 mph 32 mph 27-36 74 215 Posted Speed Liniit 30 mph Speed Justification VERT & HORIZ CURVES, EQUESTRIAN, HIDDEN DWYS Recommended Speed Limit 30 mph COLLISION HISTORY Number of Years Studied Total Collisions Statewide Average Collision Rate Collisions per Million Vehicle Miles 3 years 0 1.14 Collisions/MVM 0.00 Collisions/MVM TRAFFIC FACTORS Average Daily Traffic Number of Lanes Type of Traffic Control Crosswalks?

The 85th percentile speed is the speed at or below which 85 percent of the traffic travels. Q City of Rolling Hills (WILLDAN 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) City of Rolling Hills W I LLDAN ENGINEERING SPEED DETERMINATION City of Rolling Hills ENGINEERING SPEED DETERMINATION If the 85th percentile speed. is 33 mph, would require a round up, but can be round down to 30 mph (Option 2) City of Rolling Hills \1{ No further reduction is used WWILLDAN ENGINEERING ADDITIONAL INFO.
