Department of Public Works City of Rancho Palos Verdes 30940 Hawthorne Boulevard Rancho Palos Verdes, CA 90275 Subject: Engineering and Traffic Surveys for Palos Verdes Drive East Dear Ms. Jules: Willdan Engineering (Willdan) recommends that the following changes to the speed limits on Palos Verdes Drive East be adopted by the City Council: • Increase the speed limit from 35/40 mph to 40 mph from Palos Verdes Drive South to Ganado Drive • Retain the existing speed limit from Ganado Drive to Diamonte Lane • Retain the existing speed limit from Diamonte Lane to Miraleste Drive • Increase the speed limit from 30 mph to 35 mph from Miraleste Drive to Bronco Drive • Increase the speed limit from 30 mph to 35 mph from Bronco Drive to the North City Limit The recommended speed limits were determined in accordance with an Engineering and Traffic Survey conducted in November 2011 and certified on February 28, 2012. Our recommendation is based on a careful review of both this Engineering and Traffic Survey and the previous one conducted in 2007, as well as residents' concerns, and discussions at two Traffic Safety Commission meetings. On December 12, 2011, the Traffic Safety Commission voted to reject the findings of the recent Engineering and Traffic Survey and to recommend that the City Council maintain the existing speed limits on Palos Verdes Drive East. The higher speed limits proposed in the recent Engineering and Traffic Survey have become controversial among residents in the vicinity of Palos Verdes Drive East, with advocates who strongly support raising the speed limits and those who just as strongly oppose it. Resolution No.2012-26 Exhibt A Page 1 of 72 Ms.Nicole Jules PVDE E&T Survey March 29,2012 Page 2 Because of the controversy surrounding the proposed action, Willdan was subsequently asked to review the history behind the proposed action and make a recommendation regarding whether the existing speed limits should be maintained or if the speed limits recommended in the Engineering and Traffic Survey should be approved. Prior to discussing the history of the speed limits on Palos Verdes Drive East, a brief refresher on how speed limits are established is presented in the section below. Establishina Speed Limits in California Speed limits in California are based on the premise that the majority of people will drive at speeds that are safe for the given driving conditions. It is accepted that anyone driving above the 85th percentile speed is driving outside of the accepted norm and is therefore driving at an unsafe speed. The 85th percentile (critical) speed is defined as the speed at or below which 85% of the vehicles are observed to travel under free- flowing conditions. The 85th percentile speed is derived from a radar speed survey. In the state of California, for a speed limit to be enforced using radar, it must be established in accordance with the California Vehicle Code (CVC) and the California Manual on Uniform Traffic Control Devices(CA MUTCD), and based on an Engineering and Traffic (E&T) Survey. Currently, E&T Surveys must be updated every 5 years, although under certain circumstances, they may be extended to 7 or 10 years. The related sections of the CVC and CA MUTCD are attached. Due to training received by the Sheriffs deputies,City streets qualify for the 7-year interval at this time. An Engineering and Traffic Survey consists of the following basic elements: 1. Measurement of the prevailing speed (radar speed survey) 2. Evaluation of the traffic collision history 3. Identification of highway, traffic and roadside conditions not readily apparent to the driver When setting speed limits, streets are divided into speed zone segments, with a separate E&T Survey conducted for each one. Roadway conditions and roadside development should be consistent, as much as possible, within each speed zone, and each speed zone should normally be at least one-half mile long. Speed zones are typically one to two miles long. Shorter speed zones could potentially result in the speed limit changing back and forth within a half-mile or mile stretch, creating driver confusion. The CA MUTCD notes that when a speed limit is to be posted, it shall be established at the nearest 5 mph increment of the 85th percentile speed. For instance, if the 85th percentile speed is 37 mph, the speed limit is set at 35 mph. If it is 38 mph, then the speed limit is set at 40 mph. `�� W1LLDAN Resolution No.2012-26 .�f..: Engineering Exhibt A Page 2 of 72 Ms. Nicole Jules PVDE E&T Survey March 29,2012 Page 3 • Under certain circumstances, listed below, the speed limit can be reduced by 5 mph. 1. The California Vehicle Code allows the speed limit to be reduced for either of the following conditions: • Residential density, as defined by the CVC • Pedestrian and bicyclist safety 2. The California Manual on Uniform Traffic Control Devices notes that a speed limit may be reduced based on any of the following conditions: • Traffic collision rates • Conditions not readily apparent to the driver • Residential density • Pedestrian and bicyclist safety • Roadway characteristics, shoulder condition, grade, alignment and sight distance • Roadside development and environment • Parking practices 3. On January 1, 2012, a new law went into effect that adds a third condition for reducing the speed limit by 5 mph. In cases where the speed limit needs to be rounded up to the nearest 5 mph, the speed limit may, instead, be rounded down to the lower 5 mph increment, but it cannot be further reduced for any reason. Examples of each allowed reduction: (1) If the 85th percentile speed is 37 mph, the speed limit would be set at 35 mph. It could, however, be reduced to 30 mph for pedestrian safety. (2) If the 85th percentile speed is 38 mph, the speed limit would be set at 40 mph. It could, however, be reduced to 35 mph if there is poor sight distance (line-of-sight)from intersecting streets or driveways and the situation is not obvious to the approaching motorist. (3) If the 85 percentile speed is 43 mph and the speed limit would be set at 45 mph, the speed limit can be reduced to 40 mph, but no further. No justification is required to reduce the speed limit. Speed limits should be reduced with care, however, since speed limits are not only used to control unsafe driver behavior. They are also used by engineers in traffic design to determine the following: • The length of yellow clearance times for traffic signals • Adequate sight distance from side streets, around horizontal curves and at vertical curves • Where to place advance warning signs ` WI LLDAN Resolution No.2012-26 Engineerir� Exhibt A Page 3 of 72 Ms.Nicole Jules PVDE E&T Survey March 29,2012 Page 4 • How long a distance to provide for traffic to merge at a lane drop • How to set up signs and cones to safely and efficiently move traffic around roadway construction zones It is important to note that in order for a speed limit to be enforceable and not be deemed a speed trap, the following conditions must also be met: 1. The speed survey must be conducted by a certified radar operator and the radar gun must be certified as being properly calibrated. 2. The E&T Survey must be prepared, signed and stamped by a licensed Civil or Traffic Engineer, and approved by the City Council. The updated speed limit signs must also be installed prior to enforcement. Using the above rules and regulations, the basic steps for determining the speed limit of a street segment are as follows: 1. Measure the prevailing speed with a radar gun and calculate the 85th percentile speed. 2. Do a field review to note the characteristics of the roadway, including curves, grade, sight distance, adjacent land use, on-street parking restrictions, driveway density, number of trucks, pedestrians and bicycles, residential density and any conditions that might not be readily apparent to a motorist. 3. Collect traffic collision data (for at least the two most recent years) and daily traffic counts. Calculate the collision rate. Compare the collision rate to published standards to determine if the segment has a higher than expected collision rate. 4. Tentatively determine the speed limit by rounding the 85th percentile speed to the nearest 5 mph increment. 5. Review the collected roadway data and determine if a situation exists which would meet any of the previously noted conditions that permit reducing the speed limit by 5 mph. • If not, recommend adopting the speed limit arrived at by rounding to the nearest 5 mph increment. • If so, review the pace speed and other factors to determine if the speed limit should be reduced. If so, recommend adopting the speed limit arrived at by reducing the rounded speed limit by 5 mph. Recent History of Palos Verdes Drive East Speed Limfts Palos Verdes Drive East presents special challenges in selling speed limits. Normally, speeds on city streets are relatively consistent from one block to the next since they have the same or similar characteristics. This is not the case on Palos Verdes Drive WILLDAN Resolution No.2012-26 ' Engineering Exhibt A g Page 4 of 72 Ms. Nicole Jules PVDE E&T Survey March 29,2012 Page 5 • East, where the winding road, steep terrain, houses hugging the roadway, and varying roadway widths make it difficult to find representative sections without cutting the speed zone segment into 1/4 mile and 1/8 mile segments. Consequently, the limits of the speed zone segments must be carefully selected, so the nature of the roadway within the segment is as consistent as possible and the speed limit is appropriate for a majority of the segment. Also, as much as possible, the spots where speed surveys are taken should not be the "fastest" part of the segment, nor the "slowest", but at a point that is a good representation of the overall segment. The current speed limits on Palos Verdes Drive East were approved by the City Council based on an Engineering and Traffic Survey conducted in September 2007 by the City's then Consultant Traffic Engineer. To maintain enforceable speed limits, Cities generally update the speed limits every five years with E&T Surveys. In this case, however, the previous speed survey had been done in 2004, an interval of three years. The reason for the short time period was because on August 28, 2007, the Appellate Division of the Los Angeles Superior Court ruled that the 35 mph speed zone on Palos Verdes Drive East between Ganado Drive and Diamonte Lane was a speed trap, and, therefore, could not be enforced with radar. It was Staffs opinion at the time that the 2004 E&T Survey was proper, but that it did not explain the reasons for maintaining the 35 mph zone in sufficient detail to allow the Court to affirm its validity. To address the issue, Staff resurveyed the entire length of Palos Verdes Drive East (see attached Traffic Safety Commission Staff Report, September 24, 2007). This time, it was done in extreme detail, to the point that each of the four speed zone segments was broken down into two or more sub-segments,to accommodate the varying roadway character and driving patterns within each speed zone. This approach demonstrated that each speed zone segment might have more than one roadway character, but that each of these sub-segments was too short to be considered as a speed zone on its own. The recommended speed limit of each segment was based on the speed limit for the roadway character present in the majority of the segment's length. In July 2011, the City received a petition circulated by residents who had received speeding citations, claiming that the speed limits on Palos Verdes Drive East were too low and had been improperly set. In particular, the petitioners requested that radar enforcement of the speed limits of two segments of Palos Verdes Drive East be suspended until new surveys could be performed. The two speed zones in question were the 2.2 mile segment of Palos Verdes Drive East from Miraleste to the north City Limit and the 0.7 mile segment between Casalina and 30438 Palos Verdes Drive East. The City's current Traffic Engineering consultant reviewed the 2007 E&T Surveys and concluded that although they were unusual, they were acceptable and came to reasonable conclusions. Due to the residents' concern, however, the issue was presented to the Traffic Safety Commission at their September 26, 2011 meeting. The Traffic Engineering consultant gave a presentation that reviewed the rules and regulations that must be followed when setting a speed limit in order for it to be valid Resolution No.2012-26 4WWILLDAN Engineering I Exhibt A Page 5 of 72 Ms. Nicole Jules PVDE E&T Survey March 29,2012 Page 6 and enforceable, and followed that with a discussion of each of the concerns noted in the petition. The residents then presented their concerns about the speed limits and how they are being enforced. it was noted by the Deputy Sheriff in attendance that most officers cite drivers traveling at least 10-12 mph above the posted speed limit and that the court usually considers the 85th percentile speed when reviewing a ticket. At the September 2011 Traffic Safety Committee meeting, it was noted that the speed limits on Palos Verdes Drive East would expire in late 2012, about the same time a resurfacing project would be in progress, and that it might be better to update the E&T Survey before the resurfacing project begins. The Commission voted to recommend that the City continue with the current enforcement in place but to order new speed surveys, to be conducted as soon as possible. Willdan Engineering performed a new E&T Survey(attached)for the full length of Palos Verdes Drive East in November 2011. It should be noted that when conducting an E&T Survey, the previous E&T Survey is typically reviewed to make sure any special conditions are included and to see if the roadway conditions have changed. In this case, the resident who first brought this issue to the City's attention, believed that the Traffic Engineering consultant was biased toward lower speed limits and that anyone who reviewed the previous E&T Surveys would also be biased. To avoid even a hint of bias, another Traffic Engineer was brought in and was told to perform the survey without any prior information or review of previous studies. Nor was she told the current speed limits, the current number of speed zone segments or the current limits of the speed zone segments. She was told to begin fresh, as if setting the speed limits for the first time. It should be noted that this Traffic Engineer has conducted Citywide E&T Surveys for dozens of Cities and they all have successfully withstood challenges. The updated E&T Survey, prepared without influence, was presented to the Traffic Safety Commission on December '12, 2011. The 2011 E&T Survey divided Palos Verdes Drive East into five segments instead of the previous four, and recommended that the current speed limits be maintained on two of the segments and increased on three others (see attached table), as previously noted. The increased speed limits would be on the segment south of Ganado Drive (from 35/40 mph to 40 mph), and on the segments north of Miraleste Drive (from 30 mph to 35 mph). Exhibit A compares the proposed speed limits with the existing speed limits. As with the September 2011 meeting, several residents were in attendance. Unlike the September meeting, however, all of the residents were opposed to increasing the speed limits on Palos Verdes Drive East (at the September meeting, all were in favor). It should be noted that those who are in favor of raising the speed limits live on residential streets off of Palos Verdes Drive East whereas those opposed have addresses on Palos Verdes Drive East. 4ffi / WILLDAN Resolution No.2012-26 :tt r:r Engineering Exhibt A Page 6 of 72 .. • • ._..._ T .y • as Ms. Nicole Jules PVDE E&T Survey March 29,2012 Page 7 Members of the Traffic Safety Commission were generally sympathetic to the concerns of the Palos Verdes Drive East residents, however, no further reductions to the recommended speed limits could be legally made. Rather than increasing the speed limits, the Traffic Safety Commission voted to leave the speed limits as they currently are. Recommendations As part of our speed limit review for Palos Verdes Drive East, we conducted an independent field review of Palos Verdes Drive East relative to the increased speed limits recommended in the recent Engineering and Traffic Survey. We found that the selected study segments and locations of the speed surveys were appropriate to meet federal and state requirements. After a careful review of the 2007 and 2011 Engineering and Traffic Surveys, residents' concerns, and discussions at the two Traffic Safety Commission meetings, we do not concur with the Traffic Safety Commission's recommendation to maintain the existing speed limits. Instead, we recommend that the following speed limits for Palos Verdes Drive East, as determined by the Engineering and Traffic Survey, be adopted by the City Council: • Palos Verdes Drive South to Ganado Drive: 40 mph • Ganado Drive to Diamonte Lane: 35 mph • • Diamonte Lane to Miraleste Drive: 35 mph • Miraleste Drive to Bronco Drive: 35 mph • Bronco Drive to North City Limit: 35 mph We appreciate resident concerns, however, about increasing the speed limits on certain sections of Palos Verdes Drive East. Our field survey also found that if the speed limits are increased, horizontal curves in the affected segments should be reviewed to ensure additional/new warning signs with lower speeds are installed in conjunction with updated speed limit signs. The combined curve signs and speed warning signs would tend to have an effect similar to posting a lower speed limit. We also recommend that a "multiple" curve warning sign with a warning speed of 30 or 35 mph be considered in advance of both ends of the switchback area. Should the City Council approve the higher speed limits, we also recommend implementing traffic calming measures, such as speed feedback signs in areas of the greatest speeding/collisions, prior to installing updated speed limit signs.

Ms. Nicole Jules PVDE E&T Survey March 29,2012 Page 8 To effectively reduce speeding over the long-term, the roadway conditions must change. The City recognizes this and has already taken steps to reduce speeds on Palos Verdes Drive East. The City's Capital Improvement Program includes plans to implement traffic calming measures,on Palos Verdes Drive East, including the following: 1. Reducing the existing 4-lane section of Palos Verdes Drive East in the vicinity of Crest Road back to one lane in each direction (two lanes in each direction can be kept at the intersection with Crest Road to maintain a passing lane). 2. Installing equestrian/pedestrian paths and bike lanes in the vicinity of Deadman's Curve, and between Headland Drive and Miraleste Drive, and installing an equestrian/pedestrian crossing at Bronco Drive. We appreciate the opportunity to serve the City of Rancho Palos Verdes and the assistance and cooperation afforded to us during the course of this study.

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. (C)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 is not required to erect any sign pursuant to this paragraph until donations from private sources covering those costs are received and the local agency makes a determination that the proposed signing should be implemented. A local authority may, however, utilize any other funds available to it to pay for the erection of those signs. (b) This section shall become operative on March 1, 2001.

(a) Whenever a local authority determines upon the basis of an engineering and traffic survey that a speed greater than 25 miles per hour would facilitate the orderly movement of vehicular traffic and would be reasonable and safe upon any street other than a state highway otherwise subject to a prima facie limit of 25 miles per hour,the local authority may by ordinance determine and declare a prima facie speed limit of 30,35,40,45,50,55 or 60 miles per hour or a maximum speed limit of 65 miles per hour, whichever is found most appropriate to facilitate the orderly movement of traffic and is reasonable and safe. The declared prima facie or maximum speed limit shall be effective when appropriate signs giving notice thereof are erected upon the street and shall not thereafter be revised except upon the basis of an engineering and traffic survey. This section does not apply to any 25 mile per hour prima facie limit,which is applicable when passing a school building or the grounds thereof or when passing a senior center or other facility primarily used by senior citizens. (b) This section shall become operative on the date specified in subdivision (c) of Section 22366. Downward Speed Zoning Section 22358.5. It is the intent of the Legislature that physical conditions such as width, curvature, grade and surface conditions, or any other condition readily apparent to a driver, in the absence of other factors,would not require special downward speed zoning, as the basic rule of Section 22350 is sufficient regulation as to such conditions. Boundary Line Streets Section 22359. With respect to boundary line streets and highways where portions thereof are within different jurisdictions, no ordinance adopted under Sections 22357 and 22358 shall be effective as to any such portion until all authorities having jurisdiction of the portions of the street concerned have approved the same. This section shall not apply in the case of boundary line streets consisting of separate roadways within different jurisdictions. Speed Trap Prohibition Section 40801. No peace officer or other person shall use a speedtrap in arresting, or participating or assisting in the arrest of,any person for any alleged violation of this code nor shall any speed trap be used in securing evidence as to the speed of any vehicle for the purpose of an arrest or prosecution under this code.

(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 a 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 defined by the latest functional usage and federal-aid system maps submitted to the federal Highway Administration,except that when these maps have not been submitted,or when the street or road is not shown on the maps, a "local street or road" means a street or road that primarily provides access to abutting residential property and meets the following three conditions: (A) Roadway width of not more than 40 feet. (B) Not more than one-half mile of an uninterrupted length. Interruptions shall include official traffic control devices as defined in Section 445. (C) Not more than one traffic lane in each direction. (2) For purposes of this section"school zone"means that area approaching or passing a school building or the grounds thereof that is contiguous to a highway and on which is posted a standard"SCHOOL"warning sign,while children are going to or leaving the school either during school hours or during the noon recess period. "School zone"also includes the area approaching or passing any school grounds that are not separated from the highway by a fence,gate,or other physical barrier while the grounds are in use by children if that highway is posted with a standard"SCHOOL"warning sign. (c)(1) When all the following criteria are met, paragraph(2)of this subdivision shall be applicable and subdivision (a)shall not be applicable: (A) When radar is used, the arresting officer has successfully completed a radar operator course of not less than 24 hours on the use of police traffic radar,and the course was approved and certified by the Commission on Peace Officer Standards and Training. (B) When laser or any other electronic device is used to measure the speed of moving objects, the arresting officer has successfully completed the training required in subparagraph (A) and an additional training course of not less than two hours approved and certified by the Commission on Peace Officer Standards and Training. Resolution Mb.2012-26 Exhibt A Page 14 of 72 (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: (I) 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 of a vehicle when the evidence is based upon or obtained from or by the maintenance or use of a speedtrap. Resolution F .2012-26 Exhibt A Page 15 of 72 (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 fable case that the evidence or testimony is not based upon a speed trap as defined in paragraph (2)subdivision(a)of Section 40802.

A copy of Section 28.13 begins on the following page. • Resolution loo.2012-26 Exhibt A Page 18 of 72 California MUTCD 2012 Edition Page 141 (FHWA's MUTCD 2009 Edition,as amended for use in California) • Section 2B.13 Speed Limit Sian(R2-1) Support: oa The setting of speed limits can be controversial and requires a rational and defensible determination to maintain public confidence.Speed limits are normally set near the 85th-percentile speed that statistically represents one standard deviation above the average speed and establishes the upper limit of what is considered reasonable and prudent. As with most laws, speed limits need to depend on the voluntary compliance of the greater majority of motorists. Speed limits cannot be set arbitrarily low,as this would create violators of the majority of drivers and would not command the respect of the public. Standard: 01 Speed zones(other than statutory speed limits)shall only be established on the basis of an engineering and traffic survey(E&TS)study.that has been performed in accordance with traffic engineering practices. The engineering study shall include an analysis of the current speed distribution of free-flowing vehicles. 02 The Speed Limit(R2-1)sign(see Figure 2B-3)shall display the limit established by law,ordinance, regulation,or as adopted by the authorized agency based on the engineering study.The speed limits displayed shall be in multiples of 5 mph.

Support: 06TH general,the maximum speed limits applicable to rural and urban roads are established: A. Statutorily—a maximum speed limit applicable to a particular class of road,such as freeways or city streets, that is established by State law;or B.As altered speed zones--based on engineering studies. 07 State statutory limits might restrict the maximum speed limit that can be established on a particular road, notwithstanclii.ng what an engineering study might indicate.

Option: 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 Sections 627 and 22358.5.See Standard below for documentation requirements. 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(f). Standard: 12b If the speed limit to be posted has had the 5 mph reduction applied,then an E&TS shall document in writing the conditions and justification for the lower speed limit and be approved by a registered Civil or Traffic Engineer. The reasons for the lower speed limit shall be in compliance with CVC Sections 627 and 22358.5. Support: 12c 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 the Chapter 2B—Regulatory Signs,Barricades,and Gates January 13,2012 Part 2—Signs Resolution Na.2012-26 Exhibt A Page 20 of 72 •JJ1L22.1!SJJ f.J.' . .... .aaaa..a..aa.,.tt:a....aa. .wawa ....aa..a.a...aa•,a.wa aa.ta•.a.f..r•.+.ra.r+waasaaw.waaaa•.w•.••.f.f.._ .._c..!..l\ .f_ ...na.t•t••a.ra w• a rra•••.aw.•...•.4fT.a Jt••aaa T..I.atafs.f aa..tatTa ••a a• ra..a. • •.• .wa... •..a• •t•.a. aa•••• a.aT.a. .a t.

California MUTCD 2012 Edition Page 143 (FHWA's MUTCD 2009 Edition,as amended for use in California) conditions and justification for using this lower speed limit are documented in the E&TS and approved by a registered Civil or Traffic Engineer. 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&TS and approved by a registered Civil or Traffic Engineer. 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 35mph,the speed limit can be established at 30mph,but no further reductions can be applied(which is allowed in the two examples above). Standard: 12d Examples 1 and 2 for establishing posted speed limits shall apply to engineering and traffic surveys(E&TS) performed on or after July 1,2009 in accordance with the Department's Traffic Operations Policy Directive Number 09-04 dated June 29,2009. Option: ` 12e After January 1,2012,Example 3 may be used to establish speed limits.Refer to CVC 21400(f). Support: 12f Any existing E&TS that was performed before July 1,2009 in accordance with previous traffic control device standards is not required to comply with the new criteria until it is due for reevaluation per the 5,7 or 10 year criteria. 13 Speed studies for signalized intersection approaches should be taken outside the influence area of the traffic control signal,which is generally considered to be approximately 1/2 mile, to avoid obtaining skewed results for the 85th percentile speed. Support: 14 Advance warning signs and other traffic control devices to attract the motorist's attention to a signalized intersection are usually more effective than a reduced speed limit zone. Guidance: 15 An advisory speed plaque(see Section 2C.08)mounted below a warning sign should be used to warn road users of an advisory speed for a roadway condition.A Speed Limit sign should not be used for this situation. Option: 16 Other factors that may be considered when establishing or reevaluating speed limits are the following: A.Road characteristics,shoulder condition,grade,alignment,and sight distance; B.The pace; C.Roadside development and environment; D.Parking practices and pedestrian activity;and E.Reported crash experience for at least a 12-month period. 17 Two types of Speed Limit signs may be used:one to designate passenger car speeds,including any nighttime information or minimum speed limit that might apply;and the other to show any special speed limits for trucks and other vehicles. 18 A changeable message sign that changes the speed limit for traffic and ambient conditions may be installed provided that the appropriate speed limit is displayed at the proper times. 19 A changeable message sign that displays to approaching drivers the speed at which they are traveling may be installed in conjunction with a Speed Limit sign. Guidance: 20 If a changeable message sign displaying approach speeds is installed, the legend YOUR SPEED XX MPH or such similar legend should be displayed. The color of the changeable message legend should be a yellow legend on a black background or the reverse of these colors. Support: 21 Advisory Speed signs and plaques are discussed in Sections 2C.08 and 2C.14.Temporary Traffic Control Zone Speed signs are discussed in Part 6.The WORK ZONE(G20-5aP)plaque intended for installation above a Speed Limit sign is discussed in Section 6F.12.School Speed Limit signs are discussed in Section 7B.15.

Engineering and Traffic Survey(E&TS) Support: 24 CVC Section 627 defines the term"Engineering and traffic survey"and lists its requirements. Standard: 25 An engineering and traffic survey(E&TS)shall include,among other requirements deemed necessary by the department,consideration of all of the following: A. Prevailing speeds as determined by traffic engineering measurements. B. Collision records. C. Highway,traffic,and roadside conditions not readily apparent to the driver.. Guidance: 26 The E&TS'should contain sufficient information to document that the required three items of CVC Section 627 are provided and that other conditions not readily apparent to a driver are properly identified. 27 Prevailing speeds are determined by a speed zone survey.A speed zone survey should include: A. The intent of the speed measurements is to determine the actual speed of unimpeded traffic. The speed of traffic should not be altered by concentrated law enforcement,or other means,just prior to,or while taking the speed measurements. B. Only one person is required for the field work.Speeds should be read directly from a radar or other electronic speed measuring devices;or, C. Devices,other than radar,capable of accurately distinguishing and measuring the unimpeded speed of free flowing vehicles may be used. D. A location should be selected where prevailing speeds are representative of the entire speed zone section.If speeds vary.on a given route,more than one speed zone section may be required,with separate measurements for each section.Locations for measurements should be chosen so as to minimize the effects of traffic signals or stop signs. E. Speed measurements should be taken during off-peak hours between peak traffic periods on weekdays.If there is difficulty in obtaining the desired quantity,speed measurements may be taken during any period with free flowing traffic. F. The weather should be fair(dry pavement)with no unusual conditions prevailing. G. The surveyor and equipment should not affect the traffic speeds.For this reason,an unmarked car is recommended, and the radar speed meter located as inconspicuously as possible. H. In order for the sample to be representative of the actual traffic flow,the minimum sample should be 100 vehicles in each survey.In no case should the sample contain less than 50 vehicles. 1. Short speed zones of less than 0.5 mile should be avoided,except in transition areas. J. Speed zone changes should be coordinated with changes in roadway conditions or roadside development. K. Speed zoning should be in 10 mph increments except in urban areas where 5 mph increments are preferable. L. Speed zoning should be coordinated with adjacent jurisdictions. Support: 28 Physical conditions such as width,curvature,grade and surface conditions,or any other condition readily apparent to the driver,in the absence of other factors,would not require special downward speed zoning.Refer to CVC 22358.5. Option: 29 When qualifying an appropriate speed limit,local authorities may also consider all of the following findings: A. 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 1. Upon one side of the highway,within 0.25 mile,the contiguous property fronting thereon is occupied by 13 or more separate dwelling houses or business structures. Chapter 2B—Regulatory Signs,Barricades,and Gates January 13,2012 Part 2—Signs Resolution rid.2012-26 Exhibt A Page 22 of 72 California MUTCD 2012 Edition Page 145 (FHWA's MUTCD 2009 Edition,as amended for use in California) 2. Upon both sides of the highway,collectively,within a distance of 0.25 mile the contiguous property fronting thereon is occupied by 16 or more separate dwelling houses or business structures. 3. The portion of highway is larger than 025 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. B. Pedestrian and bicyclist safety. 30 The following two methods of conducting E&TS may be used to establish speed limits: 1.State Highways-The E&TS for State highways is made under the direction of the Department of Transportation's District Traffic Engineer.The data includes: a. One copy of the Example of Speed Zone Survey Sheet(See Figure 2B-101(CA))showing: • A north arrow • Engineer's station or post mileage • Limits of the proposed zones • Appropriate notations showing type of roadside development,such as"scattered business,""solid residential,' etc.Schools adjacent to the highway are shown,but other buildings need not be plotted unless they are a ' factor in the speed recommendation or the point of termination of a speed zone. • Collision rates for the zones involved • Average daily traffic volume • Location of traffic signals,signs and markings • If the highway is divided,the limits of zones for each direction of travel • Plotted 85th percentile and pace speeds at location taken showing speed profile b. A report to the District Director that includes: • The reason for the initiation of speed zone survey. • Recommendations and supporting reasons. • The enforcement jurisdictions involved and the recommendations and opinions of those officials. • The stationing or reference post in mileage at the beginning and ending of each proposed zone and any intermediate equations.Location ties must be given to readily identifiable physical features. 2.City and County Through Highways,Arterials,Collector Roads and Local Streets. a. The short method of speed zoning is based on the premise that a reasonable speed limit is one that conforms to the actual behavior of the majority of motorists,and that by measuring motorists'speeds,one will be able to select a speed limit that is both reasonable and effective.Other factors that need to be considered include but are not limited to:the most recent two-year collision record,roadway design speed,safe stopping sight distance, superelevation,shoulder conditions,profile conditions,intersection spacing and offsets,commercial driveway characteristics,and pedestrian traffic in the roadway without sidewalks. b. Determination of Existing Speed Limits-Figures 2B-103(CA)&2B-104(CA)show examples of data sheets which may be used to record speed observations.Specific types of vehicles may be tallied by use of letter symbols in appropriate squares. 31 In most situations,the short form for local streets and roads will be adequate;however,the procedure used on State highways may be used at the option of the local agency. Guidance: 32 The factors justifying a reduction below the 8P percentile speed for the posted speed limit are the same factors mentioned above. Whenever such factors are considered to establish the speed limit,they should be documented on the speed zone survey or the accompanying engineering report. 33 The establishment of a speed limit of more than 5 mph below the 8P percentile speed should be done with great care as studies have shown that establishing a speed limit at less than the 8P percentile generally results in an increase in collision rates;in addition,this may make violators of a disproportionate number of the reasonable majority of drivers. Support: 34 Generally,the most decisive evidence of conditions not readily apparent to the driver surface in collision histories. 35 Speed limits are established at or near the 85th percentile speed,which is defined as that speed at or below which 85th percent of the traffic is moving.The 85th percentile speed is often referred to as the critical speed.Pace speed is defined as the 10 mph increment of speed containing the largest number of vehicles(See Figure 2B-102(CA)).The lower limit of the Chapter 2B—Regulatory Signs,Barricades,and Gates January 13,2012 Part 2—Signs 12 Resolution No.2012-26 Exhibt A Page 23 of 72 California MUTCD 2012 Edition Page 146 (FHWA's MUTCD 2009 Edition,as amended for use in California) pace is plotted on the Speed Zone Survey Sheets as an aid in determining the proper zone limits.Speed limits higher than the 85th percentile are not generally considered reasonable and prudent.Speed limits below the 85th percentile do not ordinarily facilitate the orderly movement of traffic and require constant enforcement to maintain compliance.Speed limits established on the basis of the 85th percentile conform to the consensus of those who drive highways as to what speed is reasonable and prudent,and are not dependent on the judgment of one or a few individuals. 38 The majority of drivers comply with the basic speed law.Speed limits set at or near the 85th percentile speed provide law enforcement officers with a limit to cite drivers who will not conform to what the majority considers reasonable and prudent. Further studies show that establishing a speed limit at less than the 85th percentile(Critical Speed)generally results in an increase In collision rates. Option: 37 When roadside development results in traffic conflicts and unusual conditions which are not readily apparent to drivers, as indicated in collision records,speed limits somewhat below the 85th percentile may be justified.Concurrence and support of enforcement officials are necessary for the successful operation of a restricted speed zone. Guidance: 38 Speed zones of less than 0.5 mile and short transition zones should be avoided.

TO: TRAFFIC SAFETY COMMISSION FROM: DIRECTOR OF PUBLIC WORKS BY: JACK RYDELL, P.E.,T.E., PTOE, CONSULTANT TRAFFIC ENGINEER DATE: SEPTEMBER 24 2007 SUBJECT: SPEED ZONE SURVEY PALOS VERDES DRIVE EAST RECOMMENDATIONS 1. Establish a 40 mph speed zone on Palos Verdes Drive East between Palos Verdes Drive South and a point 2,900 feet north of Palos Verdes Drive South. 2. Establish a 35 mph speed zone on Palos Verdes Drive East between a point 2,900 feet north of Palos Verdes Drive South and Crest Road. 3. Establish a 35 mph speed zone on Palos Verdes Drive East between Crest Road and Miraleste Drive. 4. Establish a 30 mph speed zone on Palos Verdes Drive East between Miraleste Drive and the Rolling Hills Estates City Limit. BACKGROUND' The existing speed zones on Palos Verdes Drive East(PVDE)were established in 2004 after approval by the then Traffic Committee and adoption by the City Council. The 2004 recommendations retained the speed zones that were in effect prior to 2004. The existing speed zones on Palos Verdes Drive East are as follows: 1. 35 mph between Palos Verdes Drive South and Ganado Drive; 2. 35 mph between Ganado Drive and Diamonte Lane; 3. 30 mph between Diamonte Lane and Miraleste Drive; 4. 30 mph between Miraleste Drive and the Rolling Hills Estates City Limit. As a result of an August 28,2007 ruling by the Appellate Division of the Los Angeles Superior Court,the 35 mph speed zone between Ganado Drive and Diamonte Lane has been ruled a speed trap and,therefore,cannot be enforced by radar per Section 40801 of the California Vehicle Code(CVC). It is Staffs opinion that the 2004 Engineering and Traffic Survey was proper,but that it did not explain in sufficient detail the rationale for maintaining a 35 mph speed zone to allow the Court to affirm its validity. To address this issue,Staff has resurveyed the entirety of PVDE and Is submitting this report and the attached Engineering and Traffic Surveys. This is intended to allow the Sheriff to resume radar enforcement upon adoption of the recommended speed zones by the City Council,in compliance with Section 40802(b)of the CVC. It is Staff's belief that these surveys have been conducted in accordance with applicable provisions of the CVC and follows procedures outlined in the California Manual of Uniform Traffic Control Devices(MUTCD). DISCUSSION Section 627 of the CVC requires that Engineering and Traffic Surveys be conducted based on the methodology mandated by the California Department of Transportation,which includes: 1. Measurement of prevailing speed. Resolution No.2012-26 Exhibt A Page 26 of 72 2. Accident history. 1. Roadway characteristics not readily apparent to the motorist. 2. Residential density 3. Pedestrian and bicyclist safety. The specific procedures for conducting Engineering and Traffic Surveys are contained in Sections 2B.13 through 2B.18 of the MUTCD(Attachment C). Speed limits set by these procedures are enforceable by radar. With respect to PVDE in particular, radar enforcement appears to be the only reasonable method of enforcement as the roadway configuration(width,curvature, non-vehicular use,etc.)does not lend itself to pacing of vehicles. Therefore,any speed zone that is not based on the MUTCD procedures(such as arbitrarily setting a speed limit)would have the following consequences: 1. Radar enforcement could not be utilized,potentially compromising safety by restricting the ability to control dearly unreasonable driving behavior; 2. Speed zones set artificially low would make a large number of reasonable drivers"unlawful,"and do not facilitate the orderly flow of traffic. 3. Speed limits set higher than the prevailing speed are not considered reasonable and safe. 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 require special downward speed zoning. The basic rule of Section 22350 is sufficient to regulate such conditions. Procedures in the MUTCD specify that speed limits are generally established at the nearest 85th percentile speed(also referred to as the"critical"or"prevailing"speed),which is defined as that speed at or below which 85th percent of the traffic is moving. The MUTCD further states that the speed limit may be reduced by 5 mph from the nearest 5 mph increment of the 85th-percentile speed,where an engineering study indicates the need for a reduction in speed to match existing conditions with the traffic safety needs of the community. Factors that would support such a reduction include bicycle and pedestrian safety,residential frontage,visibility limitations,parking activities,road characteristics and any other factors not readily apparent to motorists. Posted speed zones are primarily established to protect the general public from the unreasonable behavior of reckless, unreliable,or otherwise dangerous drivers. They provide law enforcement with the means to identify and apprehend violators of the basic speed law(Section 22350 of the CVC). This statute states that"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." The basic fundamentals for establishing speed zones recognize that the majority of drivers behave in a safe and reasonable manner,and that the normally careful and competent actions of a reasonable driver should be considered legal. Speed zones established on these fundamentals conform to the consensus of those who drive the highway as to what speed is reasonable and safe,and are not dependent on the judgment of one or a few individuals. A radar or pneumatic tube speed survey is usually used to determine the prevailing speed of reasonable drivers. Speed zones are also established to advise of conditions,which may not be readily apparent to a reasonable driver. For this reason,accident history,unexpected roadway conditions,traffic characteristics,and land use must also be analyzed before determining speed zones. Speed zone changes are usually coordinated with visible changes in roadway conditions or roadside developments. Unusually short zones of less than one-half(0.5)mile in length should be avoided to reduce confusion. The MUTCD specifically recommends against speed zones shorter than 0.5 miles on pages 2B-8 and 2B-10. Section 40802 of the Vehicle Code offers an exception to the required survey on local streets as defined by federal-aid system maps submitted to the Federal Highway Administration. If maps have not been submitted,local streets are defined as those streets primarily providing access to abutting residential property and meeting the following three conditions: 1. Roadway width of not more than 40 feet. 2. Not more than one-half mile of uninterrupted length. 3. Not more than one traffic lane in each direction. PROCEDURES The attached Engineering and Traffic Surveys for the City of Rancho Palos Verdes present recommended speed zones for PVDE within the City. For the purposes of this report,PVDE is considered a north-south roadway. The previous Engineering and Traffic Surveys separated PVDE into four(4)separate segments,with limits indicated in the previous section of this Resolution No.2012-26 Exhibt A Page 27 of 72 report. This report recommends that PVDE still be separated into four(4)segments;however the limits of each segment have been modified as follows to better reflect segments with similar roadway characteristics and driving patterns. Segment A—Palos Verdes Drive South(PVDS)to 2,900 feet north of PVDS This segment is generally characterized by one travel lane in each direction with no fronting development. The northern limit (2,900 feet north of PVDS)corresponds to the southern end of the reverse horizontal curves known as the"switchbacks." This segment is approximately 0.55 miles long. Segment B—2,900 feet north of PVDS to Crest Road This segment is generally characterized by one travel lane in each direction with no fronting development and sweeping horizontal curves. The southern limit(2,900 feet north of PVDS)corresponds to the southern end of the reverse horizontal curves known as the"switchbacks"and the northern limit is located at the traffic signal controlled Crest Road. This is the only traffic signal or stop sign location on PVDE(other than at the southern terminus at PVDS. This segment is approximately 1.36 miles long. Segment C—Crest Road to Miraleste Drive This segment is generally characterized by one travel lane in each direction with substantial fronting single-family residential development and numerous sharp,horizontal curves. In addition to driveway access,there are several intersecting public and private roadways. The southern limit is located at the traffic signal controlled Crest Road and the northern limit is located at Miraleste Drive,which is a significant intersecting roadway. This segment is approximately 1.45 miles long. Within this segment is an extremely short portion of roadway that has two lanes in each direction. This portion,between Crest Road!and Calle Aventura,is only approximately 0.24 miles long. The MUTCD,which specifies the procedures for establishing speed zones,states that speed zones should not be less than 0.5 miles. In addition to this direction contained within the MUTCD,short speed zones are not appropriate due to their adverse effect on traffic safety by: 1. Increasing motorist confusion and potentially unexpected driver behavior due to changing traffic regulations,especially when a speed zone with a higher limit is sandwiched between two speed zones with lower limits; 2. Hampering enforcement efforts by issues associated with speed limit boundaries;and, 3. Increasing the potential for motorists to drive at different speeds,which increases conflict and accident potential Based on this information,it is inappropriate and contrary to MUTCD procedures for the portion between Crest Road and Calle Aventura to have a separate speed zone from adjacent roadway segments. Therefore,this short portion has been combined with the much longer portion to the north(approximately 1.21 miles long)in order to create an enforceable speed zone segment. • Segment D--Miraleste Drive to the Rolling Hills Estates City Limit This segment is generally characterized by one travel lane in each direction with substantial fronting single-family residential development and numerous sharp,horizontal curves. In addition to driveway access,there are several intersecting public and private roadways. The southern limit is located at Miraleste Drive,which is a significant intersecting roadway,and the northern limit is located at the Rolling Hills Estates City Limit,south of Conestoga Drive. This segment is approximately 2.20 • miles long. To the north,the City of Rolling Hills Estates has a posted speed limit of 40 mph. DATA COLLECTION Data was obtained regarding the prevailing speed of vehicles,traffic collisions,visibility restrictions,and roadway conditions within the project area. Radar speed measurements were conducted in September 2007. To ensure that the speed of motorists was thoroughly evaluated,measurements were taken at the following locations and for the reasons stated: Segment A—2,200 feet north of PVDS This location represents motorists who are south of the switchbacks between the limits of PVDS and 2,900 feet north of PVDS. The northern limit of this segment corresponds with the southern limit of the switchbacks. Since this segment has a length greater than 0.5 miles,it can legitimately have its own speed zone per MUTCD procedures. Resolution No.2012-26 Exhibt A Page 28 of 72 Segment B1—4,600 feet north of PVDS This location represents motorists who are within the switchbacks between the limits of 2,900 feet north of PVDS and 2,200 feet south of Ganado Drive. The limits of this segment portion generally correspond with the limits of the switchbacks. Since this segment portion has a length of 0.47 miles(slightly less than the 0.5 miles threshold),it has been combined with portions to the north in order to legitimately have its own speed zone per MUTCD procedures. The prevailing speed of traffic in this segment portion is compatible with the prevailing speeds of the other segment portions so that a uniform speed zone can be obtained. Segment B2—1,100&1,800 feet south of Ganado Drive This location represents motorists who are between the switchbacks and Ganado Drive,which is a significant intersecting roadway. The southern limit of this segment portion generally corresponds with the northern limit of the switchbacks. Since this segment portion has a length of 0.42 miles(slightly less than the 0.5 miles threshold),it has been combined with portions to the north and south In order to legitimately have its own speed zone per MUTCD procedures. The prevailing speed of traffic in this segment portion is compatible with the prevailing speeds of the other segment portions so that a uniform speed zone can be obtained. Segment•B3—1,200 feet north of Ganado Drive This location represents motorists who are between Ganado Drive and Crest Road.2,900 feet north of PVDS and 2,200 feet south of Ganado Drive. Since this segment portion has a length of 0.47 miles(slightly less than the 0.5 miles threshold),it has been combined with portions to the south in order to legitimately have its own speed zone per MUTCD procedures. The prevailing speed of traffic in this segment portion is compatible with the prevailing speeds of the other segment portions so that a uniform speed zone can be obtained. Segment C1--1,000 feet north of Crest Road This location represents motorists who are within the only four-lane portion of PVDE, between Crest Road and Calle Aventura. This segment portion is extremely short,with a length of approximately 0.24 miles. Since this segment portion is too short to legitimately have its own speed zone per MUTCD procedures(0.5 mile minimum),it must be combined with another segment portion to establish a viable speed zone. Due to the characteristics of this portion,which has fronting residential development, intersecting roadways and driveways and is located north of the traffic signal at Crest Road,it is appropriate to combine this segment portion with the similar portion to the north,which has limits at Calle Aventura and Miraleste Drive. The 85th percentile speed on the portion of the segment that is 0.24 miles long suggests a 40 mph speed zone. However,since the 85th percentile speed on the adjacent 1.21 mile long segment portion(with which this segment portion is being combined)suggests a 35 mph speed zone,the 35 mph speed link also should be applied to this portion of the segment,because the longer segment portion is much more representative of the speed over the entire segment and,therefore,should be the basis for establishing the speed zone over the entire 1.45 mile segment. Segment C2—at Via Subida This location represents motorists who are between Calle Aventura and Miraleste Drive,which is a significant intersecting roadway. Furthermore,this portion of roadway is entirely a two-lane roadway. Since this segment has a length of approximately 1.21 miles(well above the 0.5 miles threshold)it can legitimately have its own speed zone per MUTCD procedures. However it is being combined with the portion to the south,Crest Road to Calle Aventura, in order to allow that portion of roadway to have a legal speed zone. Segment D—100 feet north of Via El Miro This location represents motorists who are between Miraleste Drive,which is a significant intersecting roadway,and the Rolling Hills Estates City Limit south of Conestoga Drive. This portion of roadway is entirely a two-lane roadway. Since this segment has a length of approximately 2.20 miles(well above the 0.5 miles threshold)it can legitimately have its own speed zone per MUTCD procedures. This information is shown on the Engineering and Traffic Survey sheets(Attachments A1-A7),and copies of the radar speed surveys are shown in Attachments B1-B7. The criteria and operational procedures described below were used to measure vehicle speeds with electronic radar for each of the seven(7)segment portions on PVDE. Traffic in both directions was recorded.The specific location on each roadway segment was selected after considering the following: Resolution No.2012-26 Exhibt A Page 29 of 72 1. Stop sign and traffic signal influence. 2. Visibility restrictions. 3. Uncongested traffic flow. 4. Influence from curves or other roadway conditions that would affect the normal operation of a vehicle. The surveys were conducted in good weather conditions and consisted of a minimum of 100 samples taken during off-peak periods. A hand-held radar unit was utilized in an unmarked vehicle on the segments. Due to the heavy volume and frequency of vehicles traveling in platoons,it was determined that hand-held radar measurements would produce more accurate data on the uncongested,free-flow speed of traffic than 24-hour speed data obtained with pneumatic tubes. The accident rate on the three segments is expressed in accidents per million vehicle miles(MVM). To calculate these rates, accident data was obtained for the period of August 1,2005 through July 31,2007. 24-hour volumes were obtained during May 2006 from the City's annual count program. The results of the speed measurements were computed and analyzed,and are summarized on the Engineering and Traffic Survey forams. Significant values obtained from the computations are as follows: • The critical speed,or 85th percentile speed,is the speed at or below which 85 percent of the traffic is moving. This speed is the primary guide in determining what the majority of drivers believe is safe and reasonable. • The current guideline is to set speed limits at the nearest 5 mile-per-hour(mph)increment to 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 do not conform to what the majority finds reasonable. This methodology,which is contained in the current California MUTCD,constitutes a slight change from previous guidelines that suggested setting speed limits at the nearest 5 mph increment below the critical speed. The previous guidelines were in effect when the 2004 speed zone surveys were performed. Because of this change in procedure,speed zones recommendations contained in this survey may differ from the previous recommendations even though the critical speeds may be the same. • The 10 mph pace is the 10 mph speed range which contains the most vehicles. It is a measure of the dispersion of speeds within the samples 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. • The accident data for each street segment was compared to accident rates that can be reasonably expected to occur on streets and highways,considering the volume of traffic accommodated. These anticipated accident rates have been developed by the State of California and are applicable for Caltrans District 7,which includes the City of Rancho Palos Verdes. APPLICABLE SECTIONS OF CALIFORNIA VEHICLE CODE Basic Speed Law Section 22350. No person shall drive a vehicle upon a highway at a speed greater than is reasonable or prudent having due regard for weather,visibility,the traffic on,and the surface and width of,the highway,and in no event at a speed which endangers the safety of persons or property. Speed Law Violations Section 22351. (a) The speed of any vehicle upon a highway not in excess of the limits specified in Section 22352 or established as authorized in this code is lawful unless clearly proved to be in violation of the basic speed law. (b) The speed of any vehicle upon a highway in excess of the prima facie speed limits in Section 22352 or established as authorized in this code is prima fade 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 Resolution No.2012-26 Exhibt A Page 30 of 72 Section 22352(a).The prima facie limits are as follows and the same shall be applicable unless changed as authorized in this code and,if so changed,only when signs have been erected giving notice thereof: (1) 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 clear and unobstructed view of the crossing and of any traffic on the railway for a distance of 400 feet in both directions along the 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. 1. 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 dear 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. 1. On any alley. (2) 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. 1. When 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 fade limit shall also apply when 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. 1. 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 is not required to erect any sign pursuant to this paragraph until donations from private sources covering those costs are received and the local agency makes a determination that the proposed signing should be implemented. A local authority may,however, utilize any other funds available to it to pay for the erection of those signs. Increase of Local Speed Limits to 65 Miles Per Hour Section 22357, 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 mph,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 mph,whichever is found most appropriate to facilitate the orderly movement of traffic and is reasonable and safe.'The declared prima fade or maximum speed limit shall be effective when appropriate signs giving notice thereof are erected upon the street and shall not thereafter be revised except upon the basis of an engineering and traffic survey. This section does not apply to any 25 mile per hour prima facie limit which is applicable when passing a school building or the grounds thereof or when passing a senior center or other facility primarily used by senior citizens. Decrease near Children's Playgrounds Section 22357.1 Notwithstanding Section 22357,a local authority may,by ordinance or resolution,set a prima fade speed limit of 25 miles per hour on any street,other than a state highway,adjacent to any children's playground in a public park but only during particular hours or days when children are expected to use the facilities. The 25 miles per hour speed limit shall be effective when signs giving notice of the speed limit are posted. Resolution No.2012-26 Exh i bt A Page 31 of 72 Decrease of Local Limits Section 22:358. Whenever a local authority determines upon the basis of an engineering and traffic survey that the limit of 55 mph is more than is reasonable or safe upon any portion of any street other than a state highway where the limit of 55 mph is acceptable,the local authority,may by ordinance,determine and declare a prima facie speed limit of 50,45,40,35, 30,or 25 mph,whichever is found most appropriate to facilitate the orderly movement of traffic and is reasonable and safe, which declared prima fade limit shall be effective when appropriate signs giving notice thereof are erected upon the street.Downward Speed Zoning Section 22358.5. It is the intent of the Legislature that physical conditions such as width,curvature,grade and surface conditions,or any other condition readily apparent to a driver,in the absence of other factors,would not require special downward speed zoning,as the basic rule of Section 22350 is sufficient regulation as to such conditions. Boundary Line Streets Section 22359. With respect to boundary line streets and highways where portions thereof are within different jurisdictions, no ordinance adopted under Sections 22357 and 22358 shall be effective as to any such portion until all authorities having jurisdiction of the portions of the street concerned have approved the same. This section shall not apply in the case of boundary line streets consisting of separate roadways within different jurisdictions. Speedtrap Prohibition Section 40801. No peace officer or other person shall use a speedtrap in arresting,or participating or assisting in the arrest of,any person for any alleged violation of this code nor shall any speedtrap be used in securing evidence as to the speed of any vehicle for the purpose of an arrest or prosecution under this code. Speedtrap Section 40802. (a) A"speedtrap"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. 1.

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 defined by the latest functional usage and federal-aid system maps submitted to the federal highway administration,except that when these maps have not been submitted,or the street or road is not shown on the maps,a"local street or road"means a street or road that primarily provides access to abutting residential property and meets the following three conditions: 1. Roadway width of not more than 40 feet. 2. Not more than one-half mile of uninterrupted length. Interruptions shall include official traffic control signals as defined in Section 445. Resolution No.2012-26 Exhibt A Page 32 of 72 3. Not more than one traffic lane in each direction. (2)For the purposes of this section"school zone"means that area of road contiguous to a school building or the grounds thereof,and on which is posted a standard"SCHOOL"warning sign,while children are going to or leaving school either during school hours or during the noon recess period. (c) (1)When all of the following criteria are met,paragraph(2)of this subdivision shall be applicable and subdivision (a)shall not be applicable: (A) When radar is used,the arresting officer has successfully completed a radar operator course of not less than 24 hours on the use of police traffic radar,and the course was approved and certified by the Commission on Peace Officer Standards and Training.

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 the alleged violation unless the citation was for a violation of Section 22349,22356 or 22406. 1. 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. 1. 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. (B)(i) A particular section of 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 the speed limit involves the use of radar or any other electronic device that measures the speed of moving objects: 1. Except as specified in sub clause(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 volumes, 10 years. (ii) This subparagraph does not apply to a local street,road or school zone. Speedtrap Evidence Resolution No.2012-26 Exhibt A Page 33 of 72 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 of a vehicle when the evidence is based upon or obtained from or by the maintenance or use of a speedtrap. (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. 1. 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 5 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 speedtrap as defined in paragraph(2)of subdivision(a)of Section 40802.

Engineering and Traffic 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 January 2012. The survey was requested by the City for the proper posting of speed limits and to enable the Sheriff's Department to utilize radar or other electronic speed measuring devices for speed enforcement. CVC Sections 40801 and 40802 require Engineering and Traffic 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)(l)]. 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(cX2)(B)(i)(ll)]. These provisions assure that posted speed limits are kept reasonably current. The Engineering and Traffic Surveys for the City were conducted in accordance with procedures outlined in the California Manual on Uniform Traffic Control Devices(California MUTCD) dated January 2012 and as required by Section 627 of the California Vehicle Code. 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 maximum speed that is reasonable and prudent under typical driving conditions.

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.

The 85th percentile speed is the speed at or below which 85 percent of the traff c 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 "basic speed limit"is established at the nearest:5-mile per hour(mph)increment to the 85th percentile speed. For example,if the 85th percentile speed is 48 mph,the basic speed limit is 50 mph. If the 85th percentile speed is 47 mph, the basic speed limit is 45 mph. Engineering and Traffic Survey 2 City of Rancho Palos Verdes Resolution No.2012-26 Exhibt A Page 40 of 72 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 5 surveyed street segments is provided in Appendix B. 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 Manual on Uniform Traffic Control Devices (California MUTCD) dated January 2012 recommends exercising great care when establishing speed limits 5 mph or more below the basic speed limit. Engineering and Traffic Survey 3 City of Rancho Palos Verdes Resolution No.2012-26 Exhibt A Page 41 of 72 SURVEY CONDITIONS SURVEY LOCATIONS The procedures described below describe the criteria and methods used to survey selected streets within the City of Rancho Palos Verdes. The specific location of the radar speed survey for each street segment was 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 5 locations during the months of November 2011. Speed Data Radar speed measurements were conducted at 5 locations during November 2011. 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. Engineering and Traffic Survey 4 City of Rancho Palos Verdes Resolution No.2012-26 Exhibt A Page 42 of 72 Collision Data Collision data was obtained from the City's SW1TRS electronic collision database. For this study, collision data was used from the latest 3 years of reported accidents from May 1, 2007 to April 30, 2010. The collision rates for the 5 segments are expressed in accidents per million vehicle miles(AIMVM). 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: Axl,000,000 R tx365 days xlxv 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 2009 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. Engineering and Traffic Survey 5 City of Rancho Palos Verdes Resolution No.2012-26 Exhibt A Page 43 of 72 ANALYSIS CRITERIA Survey data was complied and analyzed to determine the recommended speed limit in accordance with several criteria contained in The California Manual on Uniform Traffic Control Devices(California MUTCD)dated January 2012. 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 Rancho Palos Verdes. RESULTS AND RECOMMENDATIONS The Engineering and Traffic 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 an 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 California Vehicle Code (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 fade Engineering and Traffic Survey 6 City of Rancho Palos Verdes Resolution No.2012-26 Exhibt A Page 44 of 72 speed violations are actually violations of the basic speed law(Section 22350 of California Vehicle Code). 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.

Each segment is discussed below. Segment#1 —Palos Verdes Drive East—Palos Verdes Drive South to Ganado Drive This segment is currently posted at 35/40 mph and has 1 narrow through lane in each direction with an ADT of 3,261 vehicles per day. The adjacent land use is vacant land. In this section,the terrain is steep and the roadway has a series of switchbacks. The critical speed is 43 mph and would normally justify a 45 mph posted speed limit. However,due to horizontal and vertical curves and heavy bicycle traffic on the weekends, a lower speed limit is prudent. It is recommended that the speed limit be posted at 40 mph for the above reasons. Segment#2— Palos Verdes Drive East—Ganado Drive to Diamonte Lane This segment is currently posted at 35 mph and has 1 through lane in each direction with an ADT of 7,475 vehicles per day. The adjacent land use is residential and school. The critical speed is 42 mph and would normally justify a 40 mph posted speed limit. However,due horizontal and vertical curves,moderate pedestrian traffic,and heavy bicyde traffic,particularly on weekends,a lower speed limit is prudent. It is recommended that the speed limit remain at 35 mph for the above reasons. Segment#3—Palos Verdes Drive East—Diamonte Lane to Miraleste Drive This segment is currently posted at 35 mph and has 1 through lane in each direction with an ADT of 8,103 vehicles per day. The adjacent land use is residential. The critical speed is 39 mph and would normally justify a 40 mph posted speed limit. However, due to horizontal and vertical curves, a narrow roadway, hidden driveways, and hidden side streets that may not be apparent to unfamiliar drivers and to maintain uniformity among adjacent street segments,a lower speed limit is prudent. It is recommended that the speed limit remain at 35 mph for the above reasons. . Segment#4—Palos Verdes Drive East—Miraleste Drive to Bronco Drive This segment is currently posted at 30 mph and has 1 through lane in each direction with an ADT of 11,468 vehicles per day. The adjacent land use is residential and school. The critical speed is 39 mph and would normally justify a 40 mph posted speed limit. However, due to horizontal and vertical curves, various hidden driveways and side streets, uncontrolled crosswalks, and moderate pedestrian traffic that may not be apparent to unfamiliar drivers, and to maintain uniformity between adjacent street segments, a lower speed limit is prudent. It is recommended that the speed limit be posted at 35 mph for the above reasons.

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) Prevailing speeds as determined by traffic engineering measurements. (2) Accident records. • (3) 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 or 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. Basic Speed Law 22350. No person shall drive a vehicle upon a highway at a speed greater than is reasonable or prudent having due regard for weather, visibility, the traffic on, and the surface and width of, the highway, and in no event at a speed which endangers the safety of persons or property. Speed Law Violations Section 22351. (a) The speed of any vehicle upon a highway not in excess of the limits specified in Section 22352 or established as authorized in this code is lawful unless clearly proved to be in violation of the basic speed law. (b) The speed of any vehicle upon a highway in excess of the prima facie speed limits in Section 22352 or established as authorized in this code is prima facie unlawful unless the Engineering and Traffic Survey I I City of Rancho Palos Verdes Resolution No.2012-26 Exhibt A Page 49 of 72 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. (a) 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: (1) Fifteen miles per hour: A) 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. B) 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. C) On any alley. (2) Twenty-five miles per hour: A) 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. (B) 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. (C)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 is not required to erect any sign pursuant to this paragraph until donations from private sources covering those costs are received and the local agency makes a determination that the proposed signing should be implemented. A local authority may, however, utilize any other funds available to it to pay for the erection of those signs. (b) This section shall become operative on March 1, 2001.

(a) Whenever a local authority determines upon the basis of an engineering and traffic survey that a speed greater than 25 miles per hour would facilitate the orderly movement of vehicular traffic and would be reasonable and safe upon any street other than a state highway otherwise subject to a prima facie limit of 25 miles per hour,the local authority may by ordinance determine and declare a prima facie speed limit of 30,35,40,45,50,55 or 60 miles per hour or a maximum speed limit of 65 miles per hour, whichever is found most appropriate to facilitate the orderly movement of traffic and is reasonable and safe. The declared prima facie or maximum speed limit shall be effective when appropriate signs giving notice thereof are erected upon the street and shall not thereafter be revised except upon the basis of an engineering and traffic survey. This section does not apply to any 25 mile per hour prima facie limit, which is applicable when passing a school building or the grounds thereof or when passing a senior center or other facility primarily used by senior citizens. (b) This section shall become operative on the date specified in subdivision (c) of Section 22366. Downward Speed Zoning Section 22358.5. It is the intent of the Legislature that physical conditions such as width, curvature, grade and surface conditions, or any other condition readily apparent to a driver, in the absence of other factors,would not require special downward speed zoning, as the basic rule of Section 22350 is sufficient regulation as to such conditions. Boundary Line Streets Section 22359. With respect to boundary line streets and highways where portions thereof are within different jurisdictions, no ordinance adopted under Sections 22357 and 22358 shall be effective as to any such portion until all authorities having jurisdiction of the portions of the street concerned have approved the same. This section shall not apply in the case of boundary line streets consisting of separate roadways within different jurisdictions. Speed Trap Prohibition Section 40801. No peace officer or other person shall use a speedtrap in arresting,or participating or assisting in the arrest of,any person for any alleged violation of this code nor shall any speed trap be used in securing evidence as to the speed of any vehicle for the purpose of an arrest or prosecution under this code. Engineering and Traffic Survey 13 City of Rancho Palos Verdes Resolution No.2012-26 Exhibt A Page 51 of 72 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 a 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 defined by the latest functional usage and federal-aid system maps submitted to the federal Highway Administration,except that when these maps have not been submitted,or when the street or road is not shown on the maps, a "local street or road" means a street or road that primarily provides access to abutting residential property and meets the following three conditions: (A) Roadway width of not more than 40 feet. (B) Not more than one-half mile of an uninterrupted length. Interruptions shall include official traffic control devices as defined in Section 445. (C) Not more than one traffic lane in each direction. (2) For purposes of this section"school zone"means that area approaching or passing a school building or the grounds thereof that is contiguous to a highway and on which is posted a standard"SCHOOL"warning sign,while children are going to or leaving the school either during school hours or during the noon recess period. "School zone"also includes the area approaching or passing any school grounds that are not separated from the highway by a fence,gate,or other physical barrier while the grounds are in use by children if that highway is posted with a standard"SCHOOL"warning sign. (c)(1) When all the following criteria are met,paragraph(2)of this subdivision shall be applicable and subdivision (a)shall not be applicable: (A) When radar is used, the arresting officer has successfully completed a radar operator course of not less than 24 hours on the use of police traffic radar,and the course was approved and certified by the Commission on Peace Officer Standards and Training. (B) When laser or any other electronic device is used to measure the speed of moving objects, the arresting officer has successfully completed the training required in subparagraph (A) and an additional training course of not less than two hours approved and certified by the Commission on Peace Officer Standards and Training. Engineering and Traffic Survey 14 City of Rancho Palos Verdes Resolution No.2012-26 Exhibt A Page 52 of 72 (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 (0). (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.
