City Manager Nealis reported that he had discussed Mrs. Hawkins' suggestion of "double ticketing" for speeding with Captain Pettus of the Los Angeles County Sheriff's Department, Lomita Station and previous Station Captain William Mangan as well as the City Attorney and that all of these professionals could not substantiate Mrs. Hawkins' claim that "double ticketing" is permissible. Commissioners discussed the continuing problem of speeding on Crest Road and other areas of the City. The Commission further discussed the suggestion of speed bumps. Commissioner Virtue stated that, through the years, the Commission has discussed this method of curtailing speeding and each time, speed bumps are denied due to recommendations from the Traffic Engineer and the liability involved.

DATE: NOVEMBER 18, 1994 BACKGROUND At the last meeting of the Rolling Hills Traffic Commission on October 5, 1994, the attached staff report was presented to the Traffic Commission for consideration. Details of this request are elaborated in the attached report. At the October 5th meeting of the Traffic Commission, the applicant presented a vertical profile of the centerline of Buggy Whip Drive. Our Traffic Engineer had not had the opportunity to review this plan prior to that meeting. At that time, Traffic Commissioners continued this matter to today's meeting in order to have our Traffic Engineer provide a report regarding the vertical profile submitted by the applicant. Correspondence from our Traffic Engineer and a copy of the vertical profile is attached to this staff report. It would be in order for members of the Traffic Commission to consider the report and comments of the Traffic Engineer and the request of the applicant regarding the driveway. Any recommendation of the Traffic Commission will be forwarded to the City Council for consideration. CRN:mlk lbuggywhip.sta2 Printed on Recycled Paper. • • WILLDAN ASSOCIATES ❑ ENGINEERS & PLANNERS Professional Consulting Services Since 1964 October 14, 1994 Mr. Craig Nealis City Manager City of Rolling Hills 2 Portuguese Bend Road Rolling Hills, CA 90274 Subject: Driveway at One Buggy Whip Lane Dear Mr. Nealis: As directed by the Traffic Commission, I have reviewed the vertical profile of the centerline of Buggy Whip Lane as prepared by the applicant's engineer. The sight distances for both the approved and proposed driveway locations were plotted graphically onto the profile plan and measured. The distances measured were from a driver's eye height of 3.5 feet from the roadway surface. The sight distance for the approved driveway location was measured to be 190 feet. Sight distance for the proposed driveway location was measured to be 175 feet. The City's minimum standard stopping sight distance for a speed of 25 mph is 150 feet. Although both, locations meet the minimum requirement, the approved location provides greater sight distance. It was stated at the Traffic Commission that greater sight distance is achieved by placing the driveway closer to the crest of the vertical curve. This assumption is not true as is indicated by the measured sight distances. The sight distance is limited by the crest of the vertical curve. The closer the driver is to the vertical curve the less the total sight distance will be. Although the driver can see further over the crest, their vehicle is located closer to the crest than the increase in distance that can bp seen beyond it. In essence, the driveway should be at, or as far away as practical from the crest of the vertical curve. An .additional consideration concerning the location of the proposed driveway is its proximity to two existing driveways. If the driveway is placed at its proposed location, it would be approximately 45 feet from an adjacent driveway and approximately 20 feet of a driveway across the street. The proximity of the three cs) 12900 CROSSROADS PARKWAY SOUTH • SUITE 200 • INDUSTRY, CALIFORNIA 91746-3499 • (310) 908-6200 • FAX (310) 695-2120 October 14, 1994 Page 2 driveways may lead to additional confusion if vehicles were to exit simultaneously.

Date: 9/16/94 TO: HONORABLE CHAIR AND MEMBERS OF THE TRAFFIC COMMISSION FROM: CRAIG R. NEALIS, CITY MANAGER SUBJECT: CONSIDERATION OF REVISED DRIVEWAY ACCESS AT 1 BUGGY WHIP DRIVE (BLAZEVICH). DATE: SEPTEMBER 16, 1994 At the regular Traffic Commission Meeting held March 18, 1994, Commissioners made the following determination relative to the above referenced driveway: • That the driveway shall be 20 feet in width at entrance with a 26 foot wide apron; • That the southerly border of the driveway entrance be at least 105 north of the southerly property line at 1 Buggy Whip Drive; • That the trees adjacent to the driveway be trimmed to provide adequate sight distance; and • That the plans for the project be amended to reflect the recommendations of the Traffic Commission. At the regular meeting of the Traffic Commission held Friday, July 15, 1994, Commissioners considered a request for a modification of the previous conditions of approval recommended to the City Council by Traffic Commission action on March 18, 1994. At that meeting, the Commission essentially recommended to the City Council that the applicant be permitted to maintain the driveway at the temporary driveway' location fenced -off on the property. Specifics of this recommended approval included: • That the southerly border of the driveway be located 43 feet north of the southerly property line; • That the driveway apron be 26 feet in width for at least 24 feet inward from the street; Printed on Recycled Paper. • That the remaining portion of the driveway for its entire duration be a minimum of 20 feet in width; • That all tree trimming.in the area be maintained to accommodate sight distance; • That these improvements be completed in conjunction with construction of proposed development on the site; • That the applicant be permitted, following City Council approval, to utilize the driveway in its current configuration during this construction phase; • That if this project is not built or is denied by the Planning Commission, that in either case, the modifications to the driveway as recommended by the Commission be implemented by the property owner within 6 months of the date of approval/denial from the Planning Commission. Based upon a request by the applicant, the Commissioners recommended these conditions of approval for a modification to the original driveway request to the City Council, separate from the Planning Commission application, at the July 25th meeting of the City Council. At that meeting, City Councilmembers declined to take action on the recommendations of the Traffic Commission indicating that their inaction was not a denial of the modification request, but may tie the hands of the Planning Commission in considering any modifications that they deem necessary relative to the driveway approach in conjunction with the entire residential development. CURRENT PROPOSAL The current proposal identifies the driveway 15 feet north of the southerly property line. Additionally, it identifies the entire width of the driveway at 16 feet. These two issues appear to be the modification that the applicant is seeking and is presented to he Traffic Commission for consideration of recommendation to the City Council this morning. RECOMMENDATION It is recommended that members of the Traffic Commission review the request of the applicant and adjourn to a field inspection, if deemed necessary by the Commission. Any recommendation of the Commission will be forwarded to the Planning Commission and, incorporated into any Resolution, as appropriate, on this case. Background material has been compiled and is attached to this staff report for Traffic Commission consideration.

We had a short discussion of his driveway approach. Mr. Blazevich indicated that he was interested in pursuing a driveway opening that was different than the location recommended by the Traffic Commission. His desired location, approximately 20 to 25' closer to Crest Road than the Traffic Commission recommended location, was marked by plastic ribbon. Mr. Blazevich also showed me a plan of the profile of Buggy Whip Lane which illustrated the elevation of the road every 50'. The plan showed that the crest, or highest point, of the vertical curve in Buggy Whip Lane was about 50' south of the current driveway opening. Mr. Blazevich stated that his proposed driveway opening was better for driver sight distance than the Traffic Committee approved location, and the plan showed that he was correct. I did not study the plan and did not come to a conclusion about the relative merits of the two driveway approach locations. I did indicate to Mr. Blazevich that the determination of safe drive sight distance was not an exact science, and therefore, it may be difficult to predict the relative safety within 20'. Adequate driver sight distance depends on vehicle speed and driver reaction time. I also stated that driver sight distance criteria in Rolling Hills was somewhat more restrictive than other areas of Southern California due to the unique nature of the community with many retired drivers. Mr. Blazevich requested that I attend the next Planning Commission meeting to discuss the driveway issue. I stated that I could not attend without the direction of the City Manner, and that my function was to respond to questions and issues from the Traffic Commission, not the Planning Commission. I told him that I would 12900 CROSSROADS PARKWAY SOUTH • SUITE an, - ,.

DATE: JULY 15, 1994 At the regular meeting of the Rolling. Hills Traffic Commission held, Friday, March 18, 1994, Commissioners approved the driveway at 1 Buggy Whip Drive with the following conditions: • That the driveway shall be 20 feet wide at the entrance with a 26 foot wide apron. • That the southerly border of the driveway entrance be at least 105 feet north of the southerly property line at 1 Buggy Whip Drive. • That the trees adjacent to the driveway be trimmed to provide adequate site distance. • That plans for the project be amended and stamped to reflect the recommendation of the Traffic Commission. Since that time, representatives of the Rolling Hills Planning Commission denied the application for construction of the new single family residence at that location. Essentially, the application for the driveway ceased when the Planning Commission denied construction of the residence since the City Council did not overturn the Planning Commission decision. However, on June 6, 1994, an appeal for this case was filed by the applicant. In the course of that appeal, they are requesting modification to the driveway as previously approved by the Traffic Commission. This appeal has been remanded back to the Planning Commission and will be considered on July 19, 1994. Plans for the driveway show the driveway constructed approximately 5 feet north of the southerly property line. • • It would be in order for members of the Rolling Hills Traffic Commission to consider any testimony this morning and to conduct a field inspection of this driveway request.

Date: 11/18/94 HONORABLE CHAIR AND MEMBERS COMMISSION CRAIG R. NEALIS, CITY MANAGER CONSIDERATION OF REQUEST FOR DOUBLE YELLOW STRIPING ON CREST ROAD. NOVEMBER 18,1994 OF THE TRAFFIC BACKGROUND At the previous meeting of the Traffic Commission held October 5, 1994, the attached staff report was presented to the Traffic Commission for consideration. Specifically, Christa Hawkins is requesting double yellow striping on Crest Road in an attempt to provide a safer traffic environment along that roadway. At that meeting, the Traffic Commission recommended to the City Council that they authorize a one-time speed zone survey along that portion of Crest Road between Portuguese Bend Road and the Crest Gate. At the regular City Council Meeting held Monday, October 10, 1994, City Councilmembers declined to approve this request of the Traffic Commission. In that light, we have provided the Commission with copies of the speed zone survey relative to Crest Road which was completed in November, 1992. As indicated in the speed radar report, the 85th percentile speed was 35.3 miles per hour along that portion of that roadway adjacent to the Hawkins' residence. The median speed was 31.6 miles per hour. The current speed limit on that roadway is 30 miles per hour. When this traffic speed zone survey was considered by the Traffic Commission and the City Council following completion in November, 1992, no changes in any speed limits in the City of Rolling Hills were recommended or supported by the speed zone survey, the Traffic Commission and City Council. Further comments on this matter are included in the attached correspondence from the Traffic Engineer.

DATE: SEPTEMBER 16, 1994 Attached to this staff report is background material relative to the above referenced request. Attachments include an August 9, 1994 correspondence from Rolling Hills resident Christa Hawkins relating to non -visitor entrance policies to the City of Rolling Hills. This responsibility in under the purview of the Community Association. Members of the Community Association have announced stricter enforcement policies at all three gates in their September 7, 1994 Newsletter. Additionally, Ms. Hawkins is recommending increased traffic enforcement and double yellow striping on Rolling Hills roadways. In follow-up correspondence, Ms. Hawkins indicates that Crest Road would be the street to target for implementation of her striping proposal. Crest Road is currently centerlined with skip yellow. Double yellow striping of this roadway would cost approximately $6, 800, including reflector replacement. RECOMMENDATION It is recommended that members of the Traffic Commission consider the request by Christa Hawkins. CRN:mlk doubleyellow.sta Printed on Recycled Paper. August 9, 1994 A U G 1 0 1994 CITY OF ROLLING .HIS Traffic Commission City of Rolling Hills No. 2 Portuguese Bend Road Rolling Hills, California 90274 Dear Commission Members: In the July 25, 1994 Newsletter, certain Traffic Commission Items were mentioned generally regulating to striping of various roadways, posting speed limit signs at various locations, and distributing speed limit warning notices to visitors and contractors entering the City. On the assumption that the Traffic Commission is taking an affirmatively tough stand on both warning of speed limits and enforcing traffic regulations within the City, my husband and I applaud your efforts. In other gated communities we have been in, gaining access is far more difficult than Rolling Hills and, once in those communities, traffic laws are STRICTLY enforced. Moreover, speed limits tend to be lower than in Rolling Hills. Result: safe and sane driving practices for the residents of these other communities. When I have described our City practices to residents we know in other communities, they express amazement at our lax policies. It's nice to occasionally see some effort being made at improving the safety of our city streets which our family feels involves (1) reduced speed limits, e.g., 25 m.p.h. on Crest Road, (2) adequate posting of speed limit signs, (3) signage cautioning motorists to drive slowly and quietly around equestrians and, most importantly (4) strict enforcement of our traffic laws and ordinances. We do not believe that well -intended letters asking residents and their guests, who drive 60-70 m.p.h. along Crest Road, to slowdown has any impact on people who are disrespectful of traffic laws. What does work? Traffic tickets which reminds people with fines and increased insurance premiums that ignoring public safety carries with it a price tag. Even if these people don't care whether they maime or kill a person or animal, they may be moved to lighten up on the gas pedal if they have been fined once or twice or if they find their license to drive in jeopardy. After all, people such as these can buy their "peace of mind" by obeying the same law that responsible citizens obey. Traffic Commission City of Rolling Hills August 9, 1994 Page 2 In this City, I feel that the speed limit on any travelled street should be no higher than 25 m.p.h. Since I live just a few hundred feet inside the Crenshaw gate and having been passed to my left (as I am attempting to make a left turn into my driveway by persons impatient with my minding the speed limits), I feel that double/double striping the streets in ways which make it unlawful to pass drivers travelling in the same direction is striping which is long overdue. cc: City Council • • e ` l2 lli,.g Jd.PG INCORPORATED JANUARY 24, 1957 THOMAS F.

Nealis, City Manager Dear Mr. Nealis: Thank you for your letter of August 12. Respecting the double striping on City streets, I am requesting such striping on those City streets where such striping is likely to promottes safety. In that regard, the main "thoroughfares," e.g., Road, Portuguese Bend Road and tastf ield seem to be likely candidates for such striping.

However, I think for now that double striping on Crest Road would be an excellent start t.o promoting safe driving practices in the City.

Crabill, do hereby certify that this Engineering and Traffic Survey for the City of Rolling Hills was performed under my supervision and is accurate and complete. 1 certify that I am experienced in performing surveys of this type and duly registered in the State of California as a professional Traffic Engineer. i ////:/� L erry rabill Date RTE 1157 • • CITY OF ROLLING HILLS ENGINEERING & TRAFFIC SURVEY FOR SPEED LIMITS INTRODUCTION This Engineering and Traffic Survey is intended to serve as the basis for the establishment and enforcement of speed. limits for selected streets within the City of Rolling Hills. This survey was authorized by the City and independently conducted by the private consulting firm of BSI CONSULTANTS. It's purpose . was to determine if changes in prevailing conditions have occurred and are in compliance with State law for enforcement purposes. Engineering and traffic surveys for speed limits are regularly conducted once every five (5) years by governing municipalities for the purpose of complying with Section 40802b of the California Vehicle Code (CVC). This law requires that speed surveys must be performed with the use of radar or other electronic devices at locations where speed limits are to be enforced with the use of radar. The current survey must be completed within five years of the date of the preceding survey. A survey allowed to expired after five years of the previous survey would constitute a speed trap as stated below: 40802 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. A particular section of a highway with a prima facie speed limit provided by this code or by local ordinance pursuant to paragraph (1) of subdivision (b) of Section 22352, or established pursuant to Section 22354, 22357, 22358, or 22358.3, which speed limit is not justified by an engineering and traffic survey conducted within five years prior to the date of the alleged violation, and where enforcement involves the use of radar or other electronic devices which measure the speed of moving objects. (b) In addition, testimony and evidence based upon a speed trap is inadmissible in a court of Law. PURPOSE AND METHODOLOGY OF SPEED ZONE ESTABLISHMENT Speed zones are primarily established to protect the general public from the unreasonable behavior of reckless, unreliable, or otherwise dangerous drivers. Speed limits conform to the consensus of the majority of those who drive the highway as to what speed is reasonable and safe, and are not dependent upon one or a few individuals. 1 1 1 1 1 1 1 1 3 1 9 3 1 • The statistical factors used to analyze the collected speed survey data are defined in the following section. Speed zones are also established to advise of road conditions or hazards which may not be readily apparent to a reasonable driver. For this reason, a field review of related road/traffic variables is conducted which is considered in combination with the statistical data and accident history of a particular roadway segment to determine a safe and reasonable speed limit. RADAR SPEED SURVEY OPERATIONAL PROCEDURES Radar speed measurements for the subject survey were conducted in November 1992 on 8 segments in the City of Rolling Hills. The surveyed segments are listed below: STREET SEGMENT Crest Road Eastfield Drive Portuguese Bend Road Saddleback Road West City Limits to Portuguese Bend Road Portuguese Bend Road to Eastfield Drive Crest Road to Chuckwagon Road Chuckwagon Road to Palos Verdes Drive East Crest Road to Poppy Trail Poppy Trail to Saddleback Road Poppy Trail to Portuguese Bend Road Southfield Drive Crest Road to Packsaddle Road The specific survey locations on each segment were selected after determining the following criteria: a. Minimum stop sign or traffic signal influence; b. Minimum visibility restrictions; c. Uncongested traffic flow away from intersections, major driveways, crosswalks, railroad crossings and unusual turning movements; d. Minimum influence from parked vehicles, bumps, dips, curves, or poor roadway conditions. The hours of radar operation were from 8:00 am to 5:00 pm with arterial roadways being restricted to off-peak periods from 9:00 am to 4:30 pm. Speed surveys were conducted on days with fair weather and clear visibility. The radar units were mounted on the front dash board of an unmarked vehicle, with the meter reading unit sustained inside the vehicle and the calibration checked periodically using a tuning fork. 2 3 1 1 1 1 1 1 1 i 1 1 a 1 • • The operator recorded the radar speed meter readings for each location on Radar Speed Survey Field Sheets included in the Appendix Section of this report. A representative sampling of at least 100 vehicles were surveyed in each direction (or a cumulative sample of 200 vehicles for both directions). For those instances where the sampling of 100 vehicles would take an excessive amount of time, sampling was continued until a bell shaped curve was established. STATISTICAL ANALYSIS FACTORS Significant factors used to analyze the collected survey data are summarized below: 1. The critical speed, or 85th Percentile Speed, is defined as that speed at or below which 85 percent of the traffic is moving. This factor is the primary guide in determining what speeds the majority of safe and reasonable drivers are traveling. The accepted practice is to set the speed limit at or within 5 mph below the Critical Speed unless other factors require a lower limit. Speed limits set on this basis provide law enforcement officials with a means of controlling reckless or unreliable drivers who will not conform to what the majority finds reasonable. 2. The 10 MPH Pace is the 10 MPH increment range which contains the largest number of recorded vehicles. The pace is a measure of the dispersion of speeds within the sample surveyed. The accepted practice is to keep the speed limit within the 10 mph pace after considering the Critical Speed and any factors requiring a speed lower than the Critical • Speed. 3. The Median Speed, or 50th Percentile Speed, represents the mid -point value within the range of recorded speeds for a particular roadway location. That is, 50% of the vehicles travel faster than, and 50% travel slower than the median speed. This value is another measure of the central tendency of the vehicle speed distribution. 4. The 15th Percentile is that speed at or below which 15 % of the vehicles are traveling. This value is important in determining the minimum allowable speed limit, given that the vehicles traveling below this speed tend to obstruct the flow of traffic, thereby increasing the accident potential. The numerical values of the above factors are derived from the cumulative speed distribution curves (found in the Appendix Section). which are calculated for each survey location. This distribution curve represents a method of graphic analysis which compares the cumulative percentage of vehicles to the speed at which the vehicles are traveling. 14 "LLD REVIEW Examples of the field data collected for the purposes of analyzing related roadway characteristics as they pertain to determination of appropriate speed limits are listed below: 3 1 1 1 1 1 1 1 3 1. Segment length, width and alignment; 2. Level of pedestrian activity; 3. Traffic flow characteristics; 4. Number of lanes and other channelization/striping factors; 5. Frequency of intersections, driveways and on -street parking; 6. Location of stop signs, traffic signals, and other regulatory traffic control devices; 7. Roadway condition, bumps and dips; 8. Obstructions to driver/pedestrian visibility; 9. Land use and proximity of schools; 10. Uniformity with existing speed zones in adjacent jurisdictions; 11. Any other unusual conditions or hazards not readily apparent to the driver. The results of the field review of related road/traffic variables are summarized on the Engineering and Traffic Survey forms found in the Appendix of this report. ACCIDENT HISTORY The Engineering and Traffic Survey forms summarize the available accident information for the subject streets. The accident information for the City of Rolling Hills was obtained by reviewing traffic accident records from the State Wide Integrated Traffic Records System (SWITRS). The Annual accident rate figures represent the number of speed -related accidents divided by 3 years of accident records. The figures for accidents per million vehicle miles were obtained by the following formula: (No. of Speed -Related Accidents/Year) (1.000.000) (ADT) (365) (Distance of Segment in Miles) An analysis of the accident history of the subject 8 street segments revealed the overall percentage of accidents attributable to excessive or unsafe speed* was generally insignificant during the period of January 1989 to December 1991. This time period represents the most current accident history available. RESULTS AND RECOMMENDATIONS Roadway conditions such as width, number of lanes, traffic control devices, and advance warning signs identifying schools are readily apparent to the driver and should not influence the results of the Engineering and Traffic Survey. The legislature has stipulated that physical conditions such as width, curvature, grade, and roadway surface, in the absence of other factors, would not require special downward speed zoning. * Unsafe speed, as used in this context, is based on the Basic Speed Law and does not necessarily coincide with the posted or non -posted speed limits. 4 • The recommendations contained in this report are intended to establish prima facie speed limits. Prima facie limits attempt to advise the motorist, and enforcement, of the reasonable speed for a particular section of roadway for prevailing conditions. In many cases, the recommendations made produce a uniform speed limit along the road. To this end, the speed limits in adjacent jurisdictions were considered as well as along the various street segments surveyed within the City of Rolling Hills. The Engineering and Traffic Survey Sheets, presented in the Appendix, illustrate results of a thorough evaluation of the available data and indicate a recommended speed limit for each of the 8 street segments surveyed. The radar speed survey statistical data and subsequent speed limit recommendations for each of the surveyed street segments are given in tabular form in the Summary of Recommendations. This summary indicates that all of the street segments have "posted" speed limits and are recommended to remain posted at their current limits. Survey data revealed that these segments had critical speeds within approximately 5 MPH of the speed limit and/or that land use and accident data required no change in the speed limit. 5 1 CITY OF ROLLING HILLS NOVEMBER 1992 SUMMARY OF RECOMMENDATIONS PERCENT EXISTING RECOMMENDED 85th 10MPH OF SPEED SPEED PERCENTILE AVERAGE PACE VEHICLES JUSTIFI- PAGE STREET/LOCATION LIMITS LIMITS SPEED SPEED RANGE IN PACE CATION NUMBER CREST ROAD WEST CITY LIMITS TO PORTUGUESE BEND RD 30 30 35.3 31.6 28-37 84.1 NO CHANGE A-1 PORTUGUESE BEND RD TO EASTFIELD DRIVE 30 30 35.8 31.9 29-38 87.0 NO CHANGE A-4 EASTFIELD DRIVE CREST ROAD TO CHUCKWAGON RD 25 25 31.7 28.1 23-32 84.7 NO CHANGE A-7 CHUCKWAGON RD TO PALOS VERDES DR E 25 25 28.9 26.3 23-32 90.7 NO CHANGE A-10 PORTUGUESE BEND ROAD CREST RD TO POPPY TRAIL 30 30 37.7 31.1 27-36 67.9 NO CHANGE A-19 POPPY TRAIL TO SADDLEBACK RD 30 30 34.3 30.5 26-35 85.0 NO CHANGE A-22 SADDLEBACK ROAD POPPY TRAIL TO PORTUGUESE BEND RD 25 25 29.7 26.2 22-31 89.6 NO CHANGE A-31 SOUTHFILED DRIVE CREST RD TO PACKSADDLE RD 25 25 29.1. 26.0 , 21-30 92.6 NO CHANGE A-37 6 CI TY OF ROLL I N G HILLS ENGINEERING AND TRAFFIC SURVEY FIELD REVIEW FORM STREET: CREST ROAD LOCATION: PORTUGUESE BEND ROAD TO EASTFIELD DRIVE FIELD REVIEW BY: C.

Dear Mr. Nealis: The Traffic Commission requested a review of the existing speeds and proposed double -yellow striping along Crest Road. The City completed a radar speed survey in November 1992 to determine the posting of speed limits throughout the City. The results of that survey are summarized as follows: Segment 85th% Speed West City limit to Portuguese Bend Road 35.3 mph Eastfield Drive to Portuguese Bend Road 35.8 mph Average Speed 31.6 mph 31.9 mph Posted Speed 30 mph 30 mph The highest speed observed during the study along Crest Road was 40 miles per hour. The critical speeds (85th%) would be considered typical for this type of rural residential roadway. Speeds are generally higher in rural residential areas due to lower traffic volumes, few structures adjacent to the roadway, and lack of on -street parking. Crest Road is approximately 22 feet wide along its entire length from Eastfield Drive to the west City limit. There is an existing single -yellow skip stripe delineating each direction of traffic. According to the radar survey, the average daily traffic is approximately 2,000 vehicles per day. There was only one speed related accident reported in the 3 years preceding the study (January 1989 to December 1991). The installation of a double -yellow striping along the entire length of Crest Road has been suggested for controlling the perceived speeding problem. The installation of a double -yellow stripe is typically used to delineate no -passing zones and not for. speed control. Although it will make it a violation to pass other 12900 CROSSROADS PARKWAY SOUTH • SUITE 200 • INDUSTRY, CALIFORNIA 91746-3499 • (310) 908-6200 • FAX (310) 695-2120 November 7, 1994 Page 2 double -yellow striping relates to the need to identify when it would be safe for vehicles to pass. Where there is not adequate sight distance around curves no - passing zones should be indicated, while other areas should be kept available for safe passing. There are areas along Crest Road where it would be appropriate to prohibit passing. These areas would include horizontal and vertical curvature in the roadway where passing sight distance is restricted. The Caltrans recommended passing sight distance for speeds of 30 miles per hour is 1,100 feet. It is recommended that the posted speeds throughout the community be controlled by Sheriff Department enforcement. Enforcement has been shown to prove effective in controlling speeding problems in residential neighborhoods. The installation of double -yellow striping is not intended to, and will not be effective at controlling speeds; If the Commission desires, double -yellow stripingcould be placed, according to standard practice, at areas along Crest Road where the passing sight distance is restricted.

Crabill, do hereby certify that this Engineering and Traffic Survey for the City of Rolling Hills was performed under my supervision and is accurate and complete. I certify that I am experienced in performing surveys of this type and duly registered in the State of California as a professional Traffic Engineer. erry rabill RTE 1157 i .. -_, //it/`I Date 1 1 CITY OF ROLLING HILLS 1 1 1 1 1 1 1 1 1 1 ENGINEERING & TRAFFIC SURVEY FOR SPEED LIMITS INTRODUCTION This Engineering and Traffic Survey is intended to serve as the basis for the establishment and enforcement of speed. limits for selected streets within the City of Rolling Hills. This survey was authorized by the City and independently conducted by the private consulting firm of BSI CONSULTANTS. It's purpose was to determine if changes in prevailing conditions have occurred and are in compliance with State law for enforcement purposes. Engineering and traffic surveys for speed limits are regularly conducted once every five (5) years by governing municipalities for the purpose of complying with Section 40802b of the California Vehicle Code (CVC). This law requires that speed surveys must be performed with the use of radar or other electronic devices at locations where speed limits are to be enforced with the use of radar. The current survey must be completed within five years of the date of the preceding survey. A survey allowed to expired after five years of the previous survey would constitute a speed trap as stated below: 40802 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) A particular section of a highway with a prima facie speed limit provided by this code or by local ordinance pursuant to paragraph (1) of subdivision (b) of Section 22352, or established pursuant to Section 22354, 22357, 22358, or 22358.3, which speed limit is not justified by an engineering and traffic survey conducted within five years prior to the date of the alleged violation, and where enforcement involves the use of radar or other electronic devices which measure the speed of moving objects. In addition, testimony and evidence based upon a speed trap is inadmissible in a court of Law. PURPOSE AND METHODOLOGY OF SPEED ZONE ESTABLISHMENT Speed zones are primarily established to protect the general public from the unreasonable behavior of reckless, unreliable, or otherwise dangerous drivers. Speed limits conform to the consensus of the majority of those who drive the highway as to what speed is reasonable and safe, and are not dependent upon one or a few individuals. 1 • The statistical factors used to analyze the collected speed survey data are defined in the following section. Speed zones are also established to advise of road conditions or hazards which may not be readily apparent to a reasonable driver. For this reason, a field review of related road/traffic variables is conducted which is considered in combination with the statistical data and accident history of a particular roadway segment to determine a safe and reasonable speed limit. RADAR SPEED SURVEY OPERATIONAL PROCEDURES Radar speed measurements for the subject survey were conducted in November 1992 on 8 segments in the City of Rolling Hills. The surveyed segments are listed below: STREET SEGMENT 1 4 Crest Road Eastfield Drive Portuguese Bend Road Saddleback Road West City Limits to Portuguese Bend Road Portuguese Bend Road to Eastfield Drive Crest Road to Chuckwagon Road Chuckwagon Road to Palos Verdes Drive East Crest Road to Poppy Trail Poppy Trail to Saddleback Road Poppy Trail to Portuguese Bend Road Southfield Drive Crest Road to Packsaddle Road The specific survey locations on each segment were selected after determining the following criteria: a. Minimum stop sign or traffic signal influence; b. Minimum visibility restrictions; c.. Uncongested traffic flow away from intersections, major driveways, crosswalks, railroad crossings and unusual turning movements;. d. Minimum influence from parked vehicles, bumps, dips, curves, or poor roadway conditions. The hours of radar operation were from 8:00 am to 5:00 pm with arterial roadways being restricted to off-peak periods from 9:00 am to 4:30 pm. Speed surveys were conducted on days with fair weather and clear visibility. The radar units were mounted on the front dash board of an unmarked vehicle, with the meter reading unit sustained inside the vehicle and the calibration checked periodically using a tuning fork. 2 • • The operator recorded the radar speed meter readings for each location. on Radar Speed Survey Field Sheets included in the Appendix Section of this report. A representative sampling of at least 100 vehicles were surveyed in each direction (or a cumulative sample of 200 vehicles for both, directions). For those instances where the sampling of 100 vehicles would take an excessive amount of time, sampling was continued until a bell shaped curve was established. STATISTICAL ANALYSIS FACTORS Significant factors used to analyze the collected survey data are summarized below: 1. The critical speed, or 85th Percentile Speed, is defined as that speed at or below which 85 percent of the traffic is moving. This factor is the primary guide in determining what speeds the majority of safe and reasonable drivers are traveling. The accepted practice is to set the speed limit at or within 5 mph below the Critical Speed unless other factors require a lower limit. Speed limits set on this basis provide law enforcement officials with a means of controlling reckless or unreliable drivers who will not conform to what the majority finds reasonable. 2. The 10 MPH Pace is the 10 MPH increment range which contains the largest number of recorded vehicles. The pace is a measure of the dispersion of speeds within the sample surveyed. The accepted practice is to keep the speed limit within the 10 mph pace after considering the Critical Speed and any factors requiring a speed lower than the Critical Speed. 3. The Median Speed, or 50th Percentile Speed, represents the mid -point value within the range of recorded speeds for a particular roadway location. That is, 50% of the vehicles travel faster than, and 50% travel slower than the median speed. This value is another measure of the central tendency of the vehicle speed distribution. 4. The 15th Percentile is that speed at or below which 15 % of the vehicles are traveling. This value is important in determining the minimum allowable speed limit, given that the vehicles traveling below this speed tend to obstruct the flow of traffic, thereby increasing the accident potential. The numerical values of the above factors are derived from the cumulative speed distribution curves (found in the Appendix Section). which are calculated for each survey location. This distribution curve represents a method of graphic analysis which compares the cumulative percentage of vehicles to the speed at which the vehicles are traveling. FIELD REVIEW Examples of the field data collected for the purposes of analyzing related roadway characteristics as. they pertain to determination of appropriate speed limits are listed below: 3 1. Segment length, width and alignment; 2. Level of pedestrian activity; 3. Traffic flow characteristics; 4. Number of lanes and other channelization/striping factors; 5. Frequency of intersections, driveways and on -street parking; 6. Location of stop signs, traffic signals, and other regulatory traffic control devices; 7. Roadway condition, bumps and dips; 8. Obstructions to driver/pedestrian visibility; 9. Land use and proximity of schools; 10. Uniformity with existing speed zones in adjacent jurisdictions; 11. Any other unusual conditions or hazards not readily apparent to the driver. The results of the field review of related road/traffic variables are summarized on the Engineering and Traffic Survey forms found in the Appendix of this report. ACCIDENT HISTORY The Engineering and Traffic Survey forms summarize the available accident information for the subject streets. The accident information for the City of Rolling Hills was obtained by reviewing traffic accident records from the State Wide Integrated Traffic Records System (SWITRS). The Annual accident rate figures represent the number of speed -related accidents divided by 3 years of accident records. The figures for accidents per million vehicle miles were obtained by the following formula: (No. of Speed -Related Accidents/Year) (1.000.000) (ADT) (365) (Distance of Segment in Miles) An analysis of the accident history of the subject 8 street segments revealed the overall percentage of accidents attributable to excessive or unsafe speed* was generally insignificant during the period of January 1989 to December 1991. This time period represents the most current accident history available. RESULTS AND RECOMMENDATIONS Roadway conditions such as width, number of lanes, traffic control devices, and advance warning signs identifying schools are readily apparent to the driver and should not influence the results of the Engineering and Traffic Survey. The legislature has stipulated that physical conditions such as width, curvature, grade, and roadway surface, in the absence of other factors, would not require special downward speed zoning. * Unsafe speed, as used in this context, is based on the Basic .Speed Law and does not necessarily coincide with the posted or non -posted speed limits. 4 • • The recommendations contained in this report are intended to establish prima facie speed limits. Prima facie limits attempt to advise the motorist, and enforcement, of the reasonable speed for a particular section of roadway for prevailing conditions. In many cases, the recommendations made produce a uniform speed limit along the road. To this end, the speed limits in adjacent jurisdictions were considered as well as along the various street segments surveyed within the City of Rolling Hills. 1 1 The Engineering and Traffic Survey Sheets, presented in the Appendix, illustrate results of a thorough evaluation of the available data and indicate a recommended speed limit for each of the 8 street segments surveyed. The radar speed survey statistical data and subsequent speed limit recommendations for each of the surveyed street segments are given in tabular form in the Summary of Recommendations. This summary indicates that all of the street segments have "posted" speed limits and are recommended to remain posted at their current limits. Survey data revealed that these segments had critical speeds within approximately 5 MPH of the speed limit and/or that land use and accident data required no change in the speed limit. 5 1 • 1 1 1 1 1 a 1 t 1 i STREET/LOCATION CREST ROAD WEST CITY LIMITS TO PORTUGUESE BEND RD PORTUGUESE BEND RD TO EASTFIELD DRIVE EASTFIELD DRIVE CREST ROAD TO CHUCKWAGON RD CHUCKWAGON RD TO PALOS VERDES DR E PORTUGUESE BEND ROAD CITY OF ROLLING HILLS NOVEMBER 1992 SUMMARY OF RECOMMENDATIONS PERCENT EXISTING RECOMMENDED 85th 10MPH OF SPEED SPEED PERCENTILE AVERAGE PACE VEHICLES JUSTIFI- PAGE LIMITS LIMITS SPEED SPEED RANGE IN PACE CATION NUMBER 30 30 35.3 31.6 28-37 84.1 NO CHANGE A-1 30 30 35.8 31.9 29-38 87.0 NO CHANGE A-4 25 25 31.7 28.1 23-32 84.7 NO CHANGE A-7 25 25 28.9 26.3 23-32 90.7 NO CHANGE A-10 CREST RD TO POPPY TRAIL 30 30 37.7 31.1 27-36 67.9 NO CHANGE A-19 POPPY TRAIL TO SADDLEBACK RD 30 30 34.3 30.5 26-35 85.0 NO CHANGE A-22 SADDLEBACK ROAD POPPY TRAIL TO PORTUGUESE BEND RD 25 25 29.7 26.2 22-31 89.6 NO CHANGE A-31 SOUTHFILED DRIVE CREST RD TO PACKSADDLE RD 25 25 29.1 26.0 21-30 92.6 NO CHANGE A-37 CITY OF ROLL ING H ILLS ENGINEERING AND TRAFFIC SURVEY FIELD REVIEW FORM STREET: PORTUGUESE BEND ROAD FIELD REVIEW BY: C.

Date: 11/18/94 HONORABLE CHAIR AND MEMBERS OF THE TRAFFIC COMMISSION. FROM: CRAIG R. NEALIS, CITY MANAGER SUBJECT: CONSIDERATION OF INTRODUCTION OF A SPEED BUMP IN THE CITY HALL PARKING LOT. DATE: NOVEMBER 18,1994 On Wednesday, November 9, 1994, Rolling Hills Community Association Administrative Assistant Dolores Cosenza approached City Staff and indicated that she feels that vehicles need to drive slower around the rear portion of the Community Association building as vehicles enter the employee parking area. At that location, there is a pedestrian stairway which empties into the driveway area. According to Ms. Cosenza, vehicles travel through there at a high rate of speed. It was suggested that a speed bump could be used to control speeding. The cost to install such a speed bump is estimated at $245.00. It would be in order for members of the Traffic Commission to hear comments from the Traffic Engineer relating to this matter. If after receiving that information, the Traffic Commission feels that a speed bump is warranted, it would be in order to make an appropriate recommendation to the City Council is this regard.
