14 ADOPT RESOLUTION NO. 16-76 ESTABLISHING OR REVISING PRIMA FACIE SPEED LIMITS ON NEW OR CHANGED CITY STREETS
Agenda Item 14 AGENDA REPORT Reviewed: City Manager Finance Director v MEETING DATE: DECEMBER 20, 2016 TO: JEFFREY C. PARKER, CITY MANAGER FROM: DOUGLAS S. STACK, DIRECTOR OF PUBLIC WORKS/CITY ENGINEER SUBJECT: ADOPT RESOLUTION NO. 16-76 ESTABLISHING OR REVISING PRIMA FACIE SPEED LIMITS ON NEW OR CHANGED CITY STREETS SUMMARY Adoption of Resolution No. 16-76 will establish and revise speed limits on certain streets in the City of Tustin that are new or have changes in roadway conditions based upon an engineering and traffic survey as required by the California Vehicle Code. RECOMMENDATION It is recommended that the City Council adopt Resolution No. 16-76 establishing or revising Prima Facie Speed Limits on certain streets throughout the City of Tustin. FISCAL IMPACT Updating signs in accordance with adoption of Resolution No. 16-76 will cost approximately $1,500. Adequate funds have been budgeted and appropriated in Engineering Division Account No. 130-40-00-6625 (Sign Maintenance and Striping). CORRELATION TO THE STRATEGIC PLAN: Establishment and revisions of speed limits contribute to the fulfillment of the City's Strategic Plan Goal B: Public Safety and Protection of Assets. Specifically, the project implements or fosters the implementation of strategy #3, which among other items, is to ensure continuous maintenance and improvement of traffic control and transportation facilities. BACKGROUND Pursuant to the California Vehicle Code (CVC), the City has the ability to establish or revise prima facie speed limits on City streets on the basis of an engineering and traffic survey. CVC Section 627 indicates that an engineering and traffic survey needs to be conducted in accordance with methods determined by the California Department of Transportation (Caltrans) and shall include, among other requirements, consideration of all of the following: 1. Prevailing speeds as determined by traffic engineering measurements; 2. Accident records; and 3. Highway, traffic, and roadside conditions not readily apparent to the driver. Resolution No. 16-76 Establishing or Revising Prima Facie Speed Limits on New or Changed City Streets December 20, 2016 Page 2 Speed limit changes are due to changes in the public's driving characteristics, accident history of the segment, and conditions not readily apparent to drivers. Standard engineering procedures and methodologies consistent with CVC requirements have been used to conduct the current engineering and traffic survey. Adoption of Resolution No. 16-76 establishing or revising speed limits based on this survey will allow continued use of radar or other electronic means for enforcement of posted speed limits by the Tustin Police Department. DISCUSSION The CVC requires that speed limits on City streets be justified by an engineering and traffic survey conducted within five-year periods for police enforcement involving the use of radar or other electronic devices. Since this requirement was last fulfilled in 2014 with the adoption of Resolution No. 14-70 by the City Council on December 16, 2014, the 2016 engineering and traffic survey only evaluated the following streets that are new or have changes in roadway conditions: • Armstrong Avenue — Warner Avenue to Valencia Avenue (New extension to Warner Avenue) • Legacy Road — Warner Avenue to Tustin Ranch Road (New) • Nisson Road — Newport Avenue to Red Hill Avenue (North side opened to parking) • Tustin Ranch Road — 1-5 Freeway to Walnut Avenue (Changed roadway conditions) • Tustin Ranch Road — Walnut Avenue to Valencia Avenue (Changed roadway conditions) • Tustin Ranch Road — Barranca Parkway to Victory Road (Addition of Warner Avenue South) • Warner Avenue — Red Hill Avenue to Tustin Ranch Road (New) The Public Works Department/Engineering Division, with input from the Tustin Police Department, has completed the "2016 Engineering and Traffic Survey" (attached) for the City of Tustin and used it as the basis for establishing or revising speed limits for six (6) street segments in the City. Resolution No. 16-76 (Attachment 4) recommends new or revised speed limits for these select street segments. Attachment 1 indicates recommended speed limit increases for three (3) segments and Attachment 2 recommends speed limit reductions for three (3) segments. The speed limit on Nisson Road between Newport Avenue and Red Hill Avenue, which recently opened the north side to parking, did not change. With implementation of the speed limits recommended in Resolution No. ' 16-76, the Public Works Department and Police Department are confident that the enforcement of the posted speed limits by radar, or other electronic means, will be upheld in the courts, as they have been with the 2015 Engineering and Traffic Survey.

This Engineering and Traffic Survey presents recommended speed limits for 7 street segments in the City of Tustin. An Engineering and Traffic Survey is 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. This Survey 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 Survey be conducted based on the methodology required by The California Manual on Uniform Traffic Control Devices (CA MUTCD) dated November 2014. The previous Citywide survey was approved in December 2014. The City requested the new survey for the proper posting of speed limits and to enable the Police Department to utilize radar or other electronic speed measuring devices for speed enforcement. The Engineering and Traffic Survey was conducted in accordance with procedures outlined in the California Manual on Uniform Traffic Control Devices (CA MUTCD) dated November 2014 and as required by Section 627 of the California Vehicle Code. ELEMENTS OF THE ENGINEERING AND TRAFFIC SURVEY The California Manual on Uniform Traffic Control Devices (CA MUTCD) dated November 2014 specifies the methodology to be used for completing an Engineering and Traffic Survey. This methodology includes an evaluation of current vehicle speeds, accident history and conditions not readily apparent to motorists. The three basic elements of the Engineering and Traffic Survey are measurements of prevailing speed, accident history, and conditions not readily apparent to motorists. The 851' percentile speed is the speed at or below which 85 percent of the traffic travels. This threshold represents what is historically found to be a safe and reasonable speed for most drivers based on common roadway conditions. Therefore, a "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. 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. 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 setting the speed limit 5 mph below the basic speed limit. Widdan Engineering 2096 Engineering and Traffic Survey 106456 9 City of Tustin SURVEY CONDITIONS Survey locations were selected based on minimum stop sign and traffic signal influence, minimum visibility restrictions, non -congested traffic flow away from intersections and driveways, and minimum interference from curves or other roadway conditions that would affect the normal operation of a vehicle. Data was collected reflecting existing conditions, including the prevailing speed of vehicles, traffic collisions, visibility restrictions, and roadway conditions within the community. Speed data and field reviews were conducted at 7 locations during the months of September and October 2016. Collision data for each segment for the latest 3 years of reported accidents was obtained from the City's electronic database. Daily traffic volumes, collected during the month of October 2016, were provided by the City of Tustin. The collision rate in collisions per million vehicle miles (Col/MVM) was calculated for each segment, using the number of collisions, the daily traffic volumes and the segment lengths. The collision rates were compared to the statewide average for similar roadways to determine if the segments had greater than normal collision rates. The field review of each segment also noted pedestrian/bicycle activity, roadway geometrics, the frequency of intersections, driveways and on -street parking, location of traffic control devices, visibility obstructions, land use and proximity to schools and parks, speed limits of adjacent segments in neighboring jurisdictions, and any other conditions not readily apparent to the driver. ANALYSIS & RESULTS The 2016 Engineering and Traffic Survey includes 3 new street segments in and around Tustin Legacy, that were not previously surveyed in 2014. Interim speed limits had been posted on most of the new street segments, based on design speed and engineering judgment. The survey data for the 7 segments was compiled and analyzed to determine the recommended speed limit for each segment, in accordance with the criteria contained in the California Manual on Uniform Traffic Control Devices (CA MUTCD), dated November 2014. The criteria included the 85th percentile speed, the 10 mph pace speed, the collision rate and conditions not readily apparent to the motorist. Figure 1 (at the end of this section) illustrates all of the recommended speed limits, including the new segments, on a City map and indicates the recommended changes. Of the 7 surveyed segments, 3 segments are recommended for an increase in the posted speed limit, while 3 segments are recommended for a decrease in the posted speed limit. Based on the review of special conditions, 2 of the surveyed segments have recommended speed limits that are 5 mph below where it would normally be set due to the 85th percentile speed. The speed limits were lowered for these 2 segments due to conditions not readily apparent to the drivers. The special conditions justifying the modified speed limits are provided for each segment. willdan Engineering 2016 Engineering and Traffic Survey 106456 2 city of Tustin LEGISLATIVE REFERENCES Applicable sections of the California Vehicle Code are provided in the report.

This Engineering and Traffic Survey presents recommended speed limits for 7 street segments in the City of Tustin. An Engineering and Traffic Survey is 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. This Survey 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 Survey be conducted based on the methodology required by The California Manual on Uniform Traffic Control Devices (CA MUTCD) dated November 2014. The survey was requested by the City for the proper posting of speed limits and to enable the Police Department to utilize radar or other electronic speed measuring devices for speed enforcement. CVC Sections 40801 and 40802 require that an Engineering and Traffic Survey 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)(13)(i)(1)]. Additionally, some surveys may be extended to 10 years if a traffic engineer certifies that no changes in roadway or traffic conditions have occurred [CVC 40802 (c)(2)(B)(i)(11)1. These provisions assure that posted speed limits are kept reasonably current. The Engineering and Traffic Survey for the City was conducted in accordance with procedures outlined in the California Manual on Uniform Traffic Control Devices (CA MUTCD) dated November 2014 and as required by Section 627 of the California Vehicle Code. The Code further describes three elements of an Engineering and Traffic Survey: Prevailing speed as determined by traffic engineering measurements 2. Collision records 3. Highway, traffic, and roadside conditions not readily apparent to the driver 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 of identifying and apprehending 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. Willdan Engineering 2018 Engineering and Traffic Survey 106456 5 City of Tustin The basic fundamentals for establishing speed limits recognize that the majority of drivers behave in a safe and reasonable manner, and therefore, the normally careful and competent actions of a reasonable driver should be considered legal. Speed limits established on these fundamentals conform to the consensus that those who drive the highway determine what speed is reasonable and safe, not on the judgment of one or a few individuals. A radar speed study is usually used to record the prevailing speed of reasonable drivers. Speed limits are also established to advise drivers of conditions which may not be readily apparent to a reasonable driver. For this reason, accident history, roadway conditions, traffic characteristics, and land use must also be analyzed before determining speed limits. Speed limit changes are usually made in coordination with physical changes in roadway conditions or roadside developments. Unusually short zones of less than one-half mile in length should be avoided to reduce driver confusion. Additionally, it is generally accepted that speed limits cannot be successfully enforced without voluntary compliance by a majority of drivers. Consequently, only the driver whose behavior is clearly out of line with the normal flow of traffic is usually targeted for enforcement. ELEMENTS OF THE ENGINEERING AND TRAFFIC SURVEY The California Manual on Uniform Traffic Control Devices (CA MUTCD) dated November 2014 specifies the methodology to be used for completing an Engineering and Traffic Survey. This methodology includes an evaluation of current vehicle speeds, accident history and conditions not readily apparent to motorists. The basic elements of the Engineering and Traffic Survey are discussed in more detail as follows: Measurement of Prevailing Speed Existing vehicle speeds are surveyed by a certified radar operator with a calibrated radar unit in an unmarked vehicle. Speed samples are taken for each segment representing a statistically significant sample of current traffic, This data is then evaluated to identify the distribution of speeds. A key element in the evaluation is the identification of the 85th percentile speed. The 85th percentile speed is the speed at or below which 85 percent of the traffic travels. This threshold represents what is historically found to be a safe and reasonable speed for most drivers based on common roadway conditions. Therefore, a speed limit is established at the nearest 5 -mile per hour (mph) increment to the 85th percentile speed, except as shown in the two options below. Options: 1. The posted speed may be reduced by 5 mph from the nearest 5 mph increment of the 85th -percentile speed, in compliance with CVC Section 627 and 22358.5. 2. For cases in which the nearest 5 mph increment of the 85th -percentile speed would require a rounding up, then the speed limit may be rounded down to the nearest 5 Wilidan Engineering 2016 Engineering and Traffic Survey 106456 6 City of Tustin mph increment below the 851h percentile speed, if no further reduction is used. Refer to CVC Section 21400(b). 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. The reasons for the lower speed limit shall be in compliance with CVC Section 627 and 22358.5 The following examples are provided to explain the application of these speed limit criteria: A. Using Option 1 above, the first step is to round down: If the 85th percentile speed in a speed survey for a location was 37 mph, then the speed limit would be established at 35 mph since it is the closest 5 mph increment to the 37 mph speed. As indicated by the option, this 35 mph established speed limit could be reduced by 5 mph to 30 mph if conditions and justification for using this lower speed limit are documented in the E&TS. B. Using Option 1 above, the first step is to round up: If the 851h 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. C. Using Option 2 above and first step is to round up: If the 851h percentile speed in a speed survey for a location was 33 mph, instead of rounding up to 35 mph, the speed limit can be established at 30 mph, but no further reduction can be applied. Collision History Reported collisions are reviewed for each street segment to determine if there is a higher than average rate of collisions. A segment that has an above-average collision rate typically suggests conditions that are not readily apparent to motorists. A summary of the collision rates for the 7 surveyed street segments is provided in Appendix C. 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 setting the speed limit 5 mph below the basic speed limit. It is important to note that The California Manual on Uniform Traffic Control Devices (CA MUTCD) dated November 2014 recommends exercising great care when establishing speed limits 5 mph below the basic speed limit. Willdan Engineering 2096 Engineering and Traffic Survey 106456 7 City of Tustin SURVEY CONDITIONS SURVEY LOCATIONS The procedures described below describe the criteria and methods used to survey selected streets within the City of Tustin. The specific location of the radar speed surrey 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 regarding the existing conditions was collected, including the prevailing speed of vehicles, traffic collisions, visibility restrictions, and roadway conditions within the community. Speed data and field reviews were conducted at 7 locations during the month of September 2016. Speed Data Radar speed measurements were conducted at 7 locations d!u!ring September 2016. 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 and separate surveys were made for divided roadways. Collision Data Collision data was obtained from the Statewide Integrated Traffic Record System (SWITRS) which is an electronic collision database. Forthis study, collision data was used from the latest three years of reported accidents, from January 1, 2013 to December 31, 2015. The collision rates for the 7 segments are expressed in accidents per million vehicle miles (A/MVM). Daily traffic volumes, collected during the months of September and October 2016, were provided by the City of Tustin. This information was then entered into the following formula to determine the collision rate: R= Ax1,000,000 tr365 days zlxv year Willdan Engineering 2016 Engineering and Traffic Survey 106456 8 City of Tustin Where: R = Collision Rate (accidents/million vehicle miles) A = Number of midblock collisions over time period t = Time Period Covered (in years) 1= Length of Segment (miles) v = Traffic Volume (average daily traffic) The segment collision rate was then compared to the average statewide collision rate for similar roadways. The latest available average statewide collision rates were obtained from 2012 Collision Data on California State Highways, published by the State of California. 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 10. Any other unusual condition not readily apparent to the driver Willdan Engineering 2016 Engineering and Traffic Survey 106456 9 City of Tustin ANALYSIS & RESULTS ANALYSIS Survey data was compiled and analyzed to determine the recommended speed limit in accordance with several criteria contained in the Califomia Manual on Uniform Traffic Control Devices (CA MUTCD) dated November 2014. Some of the criteria used were: 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 much higher than the critical speed are not considered reasonable and safe. Speed limits set much 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 5 mph increment closest to the 851h 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 indicate 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 similar 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 Tustin. NE'11`V STREET SEGMENTS Subsequent to the 2015 Engineering and Traffic Survey, several new street segments in the City of Tustin have been constructed in and around Tustin Legacy, which was formerly occupied by the Tustin Marine Corps Air Station. This has resulted in the addition of the 3 new street segments listed below since the last Engineering and Traffic Survey was performed. Since another Engineering and Traffic Survey was due, interim speed limit signs were posted on most of the new road segments, with the speed limits based on design speed and engineering judgment. 1. Armstrong Avenue from Warner Avenue to Valencia Avenue 2. Legacy Road from Warner Avenue to Tustin Ranch Road 3. Warner Avenue from Red Hill Avenue to Tustin Ranch Road Willdan Engineering 2016 Engineering and Traffic Survey 106456 10 City of Tustin RESULTS AND RECOMMENDATIONS 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 facie 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. The Engineering and Traffic Survey Forms (Appendix A) illustrate the results of a thorough evaluation of the available data, and recommend a speed limit for each street segment surveyed. Table 1 (at the end of this section) summarizes the results and recommendations for all 7 surveyed segments. The recommended speed limit for each segment is consistent with the prevailing behavior as demonstrated by the radar speed measurements. Typically, a speed limit in the upper range of the 10 -mile pace was selected unless a collision rate significantly higher than expected was discovered or roadway conditions not readily apparent to the driver were identified. Any segments with recommended speed limits 5 mph below or above the basic speed limit are fully explained later in this section. Of the 7 surveyed segments, 3 segments are recommended for an increase in the posted speed limit, as listed in Table 2 (at the end of this section). Table 3 also indicates that 3 segments are recommended for a decrease in the posted speed limit. SEGMENTS WITH SPECIAL CONDITIONS The 7 street segments were reviewed through a field inspection to Identify whether conditions not readily apparent to motorists exist. Conditions not readily apparent to motorists include high accident rates; the design speed of the road; continuity between speed zones; on -street parking on relatively narrow streets that could block the view of pedestrians crossing the street or block the sight distance of motorists entering the roadway from cross streets or driveways, and high -activity land uses adjacent to the road. The presence of pedestrians and/or bicycles is also recognized by California law as a reason for setting the speed limit 5 mph below the basic speed limit. A determination was made whether these conditions are present and significant enough to warrant recommending the speed limit to be placed at 5 mph below the basic speed limit. It is important to note that the State of California recommends exercising great care when establishing speed limits more than 5 mph below the 8511 percentile speed. Willdan Engineering 2016 Engineering and Traffic Survey 06456 11 City of Tustin Based on the review of special conditions, 2 surveyed street segments have recommended speed limits that are 5 miles per hour (mph) below the basic speed limit, due to conditions not readily apparent to the drivers. The special conditions justifying the modified speed limits are discussed below for each of these segments. Segment #3: Nisson Road — Newport Avenue to Red Hill Avenue This segment is currently posted at 35 mph and has I through lane in each direction with an ADT of 5,879 vehicles per day. The adjacent land use is single-family and multi -family residential (non -fronting) on the south side and Interstate 5 on the north side. The critical speed is 41 mph, which would normallyjustify a 40 mph posted speed limit. However, due to a horizontal curve and heavy on -street parking that results in very limited sight distance for those entering from side streets and driveways, a lower speed limit is prudent. 1t is recommended that the speed limit remain at 35 mph for the reasons given above. Segment #5: Tustin Ranch Road — Walnut Avenue to Valencia Avenue This segment is currently posted at 55 mph and has 3 through lanes in each direction with an ADT of 26,223 vehicles per day. The adjacent land use is commercial, single family residential (non -fronting), and vacant land. The critical speed is 56 mph, which would normally justify a 55 mph posted speed limit. However, due to horizontal and vertical curves 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 be posted at 50 mph for the reasons given above.

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 dweiling 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. Uniform Standards Section 21400 (a) (1) The Department of Transportation shall, after consultation with local agencies and public hearings, adopt rules and regulations prescribing uniform standards and specifications for all official traffic control devices placed pursuant to this code, including, but not limited to, stop signs, yield right-of-way signs, speed restriction signs, railroad warning approach signs, street name signs, lines and markings on the roadway, and stock crossing signs placed pursuant to Section 21364. (2) The Department of Transportation shall, after notice and public hearing, determine and publicize the specifications for uniform types of warning signs, lights, and devices to be placed highway by a person engaged in performing work that interferes with or endangers the safe movement of traffic upon that highway. Willdan Engineering 2016 Engineering and Traffic Survey 106456 16 City of Tustin (3) Only those signs, lights, and devices as are provided for in this section shall be placed upon a highway to warn traffic of work that is being performed on the highway. (4) Control devices or markings installed upon traffic barriers on or after January 1, 1984, shall conform to the uniform standards and specifications required by this section. (b) The Department of Transportation shall revise the California Manual on Uniform Traffic Control Devices, as it read on January 1, 2012, to require the Department of Transportation or a local authority to round speed limits to the nearest five miles per hour of the 85th percentile of the free-flowing traffic. However, in cases in which the speed limit needs to be rounded up to the nearest five miles per hour increment of the 85thpercentile speed, the Department of Transportation or a local authority may decide to instead round down the speed limit to the lower five miles per hour increment, but then the Department of Transportation ora local authority shall not reduce the speed limit any further for any reason. Basic Speed Law 22350. No person shall drive a vehicle upon a highway at a speed greater than is reasonable or prudent having due regard for weather, visibility, the traffic on, and the surface and width of, the highway, and in no event at a speed which endangers the safety of persons or property. Speed Law Violations Section 22351. (a) The speed of any vehicle upon a highway not in excess of the limits specified in Section 22352 or established as authorized in this code is lawful unless clearly proved to be in violation of the basic speed law. (b) The speed of any vehicle upon a highway in excess of the prima facie speed limits in Section 22352 or established as authorized in this code is prima facie unlawful unless the defendant establishes by competent evidence that the speed in excess of said limits did not constitute a violation of the basic speed law at the time, place and under the conditions then existing. Prima Facie Speed Limits Section 22352. The prima facie limits are as follows and shall be applicable unless changed as authorized in this code and, if so changed, only when signs have been erected giving notice thereof: (a) Fifteen miles per hour: (1) When traversing a railway grade crossing, if during the last 100 feet of the approach to the crossing the driver does not have a clear and unobstructed view of the crossing and of any traffic on the railway for a distance of 400 feet in both directions along such railway. This subdivision does not apply in the case of any railway grade crossing where a human flagman is on duty or a clearly visible electrical or mechanical railway crossing signal device is installed but does not then indicate the immediate approach of a railway train or car. Willdan Engineering 2016 Engineering and Traffic Survey 106456 17 City of Tustin (2) When traversing any intersection of highways, if during the last 100 feet of the driver's approach to the intersection, the driver does not have a clear and unobstructed view of the intersection and of any traffic upon all of the highways entering the intersection for a distance of 100 feet along all those highways, except at an intersection protected by stop signs or yield right-of-way signs or controlled by official traffic control signals. (3) On any alley. (b) Twenty-five miles per hour: (1) On any highway other than a state highway, in any business or residence district unless a different speed is determined by local authority under procedures set forth in this code. (2) When approaching or passing a school building or the grounds thereof, contiguous to a highway and posted with a standard "SCHOOL" warning sign, while children are going to or leaving the school either during school hours or during the noon recess period. The prima facie limit shall also apply when approaching or passing any school grounds which are not separated from the highway by a fence, gate or other physical barrier while the grounds are in use by children and the highway is posted with a standard "SCHOOL" warning sign. For purposes of this subparagraph, standard "SCHOOL" warning signs may be placed at any distance up to 500 feet away from school grounds. (3) When passing a senior center or other facility primarily used by senior citizens, contiguous to a street other than a state highway and posted with a standard "SEN IOR" warning sign. A local authority may erect a sign pursuant to this paragraph when the local agency makes a determination that the proposed signing should be implemented. A local authority may request grant funding from the Pedestrian Safety Account pursuant to Section 894.7 of the Streets and Highways Code, or any other grant funding available to it, and use that grant funding to pay for the erection of those signs, or may utilize any other funds available to it to pay for the erection of those signs, including, but not limited to, donations from private sources. Increase of Local Speed Limits Section 22357. (a) Whenever a local authority determines upon the basis of an engineering and traffic survey that a speed greater than 25 miles per hour would facilitate the orderly movement of vehicular traffic and would be reasonable and safe upon any street other than a state highway otherwise subject to a prima facie limit of 25 miles per hour, the local authority may by ordinance determine and declare a prima facie speed limit of 30, 35, 40, 45, 50, 55 or 60 miles per hour or a maximum speed limit of 65 miles per hour, whichever is found most appropriate to facilitate the orderly movement of traffic and is reasonable and safe, The declared prima facie or maximum speed limit shall be effective when appropriate signs giving notice thereof are erected upon the street and shall not thereafter be revised except upon the basis of an engineering and traffic survey. This section does not apply to any 25 mile per hour prima facie limit, which is applicable when passing a school building or the grounds thereof or when passing a senior center or other facility primarily used by senior citizens. Willdan Engineering 2016 Engineering and Traffic Survey 106456 18 City of Tustin (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. Speed Trap Section 40802. (a) A "speed trap" is either of the following: (1) A particular section of a highway measured as to distance and with boundaries marked, designated, or otherwise determined in order that the speed of a vehicle may be calculated by securing the time it takes the vehicle to travel the known distance. (2) A particular section of a highway with a prima facie speed limit that is provided by this code or by local ordinance under subparagraph (A) of paragraph (2) of subdivision (a) of Section 22352, or established under Section 22354, 22357, 22358, or 22358.3, if that prima facie speed limit is not justified by an engineering and traffic survey conducted within five years prior to the date of the alleged violation, and enforcement of the speed limit involves the use of radar or any other electronic device that measures the speed of moving object. This paragraph does not apply to a local street, road, or school zone. (b)(1) For purposes of this section, a local street or road is one that is functionally classified as "local" on the "California Road System Maps," that are approved by the Federal Highway Administration and maintained by the Department of Transportation. When a street or road Wiildan Engineering 2096 Engineering and Traffic Survey 106456 19 City of Tustin does not appear on the "California Road System Maps," it may be defined as a "local street or road" if it primarily provides access to abutting residential property and meets the following three conditions: (A) Roadway width of not more than 40 feet. (B) Not more than one-half of a mile of uninterrupted length. Interruptions shall include official traffic control signals as defined in Section 445. (C) Not more than one traffic lane in each direction. (2) For purposes of this section "school zone" means that area approaching or passing a school building or the grounds thereof that is contiguous to a highway and on which is posted a standard "SCHOOL" warning sign, while children are going to or leaving the school either during school hours or during the noon recess period. "School zone" also includes the area approaching or passing any school grounds that are not separated from the highway by a fence, gate, or other physical barrier while the grounds are in use by children if that highway is posted with a standard "SCHOOL" warning sign. (c)(1) When all the following criteria are met, paragraph (2) of this subdivision shall be applicable and subdivision (a) shall not be applicable: (A) When radar is used, the arresting officer has successfully completed a radar operator course of not less than 24 hours on the use of police traffic radar, and the course was approved and certified by the Commission on Peace Officer Standards and Training. (B) When laser or any other electronic device is used to measure the speed of moving objects, the arresting officer has successfully completed the training required in subparagraph (A) and an additional training course of not less than two hours approved and certified by the Commission on Peace Officer Standards and Training. (C)(i) The prosecution proved that the arresting officer complied with subparagraphs (A) and (B) and that an engineering and traffic survey has been conducted in accordance with subparagraph (B) of paragraph (2). The prosecution proved that, prior to the officer issuing the notice to appear, the arresting officer established that the radar, laser, or other electronic device conformed to the requirements of subparagraph (D). (ii) The prosecution proved the speed of the accused was unsafe for the conditions present at the time of alleged violation unless the citation was for a violation of Section 22349, 22356, or 22406. (D) The radar, laser, or other electronic device used to measure the speed of the accused meets or exceeds the minimal operational standards of the National Traffic Highway Safety Administration, and has been calibrated within the three years prior to the date of the alleged violation by an independent certified laser or radar repair and testing or calibration facility. (2) A "speed trap" is either of the following: (A) A particular section of a highway measured as to distance and with boundaries marked, designated, or otherwise determined in order that the speed of a vehicle Willdan Engineering 2016 Engineering and Traffic Survey 106456 20 City of Tustin may be calculated by securing the time it takes the vehicle to travel the known distance. (13)(i) A particular section of a highway or state highway with a prima facie speed limit that is provided by this code or by local ordinance under subparagraph (A) of paragraph (2) of subdivision (a) of Section 22352, or established under Section 22354, 22357, 22358, or 22358.3, if that prima facie speed limit is not justified by an engineering and traffic survey conducted within one of the following time periods, prior to the date of the alleged violation, and enforcement of speed limit involves the use of radar or any other electronic device that measures the speed of moving objects: (1) Except as specified in subclause (11), 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. (b) In any prosecution under this code of a charge involving the speed of a vehicle, where enforcement involves the use of radar or other electronic devices which measure the speed of moving objects, the prosecution shall establish, as part of its prima facie case, that the evidence or testimony presented is not based upon a speed trap as defined in paragraph (2) of subdivision (a) of Section 40802. (c) When a traffic and engineering survey is required pursuant to paragraph (2) of subdivision (a) of Section 40802, evidence that a traffic and engineering survey has been conducted within five years of the date of the alleged violation or evidence that the offense was committed on a local street or road as defined in paragraph (2) of subdivision (a) of Section 40802 shall constitute a prima facie case that the evidence or testimony is not based upon a speed trap as defined in paragraph (2) subdivision (a) of Section 40802.
