Engineering and Traffic Survey June 2023
INTRODUCTION
This Engineering and Traffic Survey is intended to serve as the basis for the establishment and enforcement of speed limits for selected streets within the City of Santa Clarita (City). This survey was authorized by the City and independently conducted by the private consulting firm Kimley-Horn and Associates, Inc.
Engineering and traffic surveys for speed limits are regularly conducted once every five (5) years by governing municipalities for the purpose of complying with Section 40802(a) of the California Vehicle Code (CVC) and the national Uniform Vehicle Code. Engineering and traffic surveys may be conducted every seven (7) years if criteria is met, or every ten (10) years if a registered engineer evaluates the section of the highway and determines that no significant changes in roadway or traffic conditions have occurred as specified in Section 40802(c) of theCalifornia Vehicle Code (CVC). In addition, an engineering and traffic survey should be conducted on newly constructed roadways or roadways where the roadway conditions have significantly changed (changes to lane configuration or roadway striping).
The current survey must be completed within five years as specified in Section 40802(a); seven years as specified in Section 40802(c), or ten years as specified in Section 40802(c), of the date of the preceding survey. A survey allowed to expire after five years (as specified by Section 40802(a)), seven years (as specified by Section 40802(c)), or 10 years (as specified by Section 40802(c)), of the previous survey would constitute a speed trap as stated below:
40802. 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 involves the use of radar or any other electronic device that measures the speed of moving objects.
In addition, testimony and evidence based upon a speed trap is inadmissible in a court of law.

PURPOSE AND METHODOLOGY OF SPEED ZONE ESTABLISHMENT
Speed zones are primarily established to protect the general public from the unreasonable behavior of reckless, unreliable, or otherwise dangerous drivers. Speed limits are generally established at or near the 85th percentile speed, which is defined as the speed at or below which 85 percent of traffic is moving. Speed limits established on this basis conform to the consensus of those who drive on the highways as to what speed is reasonable and safe and are not dependent on the judgment of one or a few individuals.
The Engineering and Traffic Survey, as defined in Section 627 of the CVC, must consider the prevailing speeds, collision records, pedestrian and bicycle activity, and roadway traffic and roadside conditions not readily apparent to the driver. Speed zones are also established to advice of road conditions or hazards, which may not be readily apparent to a reasonable driver. For this reason, a field review of related road/traffic variables is conducted which is considered in combination with the statistical data and collision history of a particular roadway segment to determine a safe and reasonable speed limit. The specific procedures used in the conduct of the Engineering and Traffic Study are outlined in the CaliforniaMUTCD 2014 Edition, Revision 6. The statistical factors used to analyze the collected speed survey data are defined in the following section.
It should be noted that the CVC allows local authorities to increase or decrease the prima facie limits by ordinance or resolution to appropriate limits as determined by an engineering and traffic survey.
Posted speed limits not defined in the CVC or established by ordinance are not valid.
According to Section 22352(a)(2)(A) of the CVC, the prima facie speed limit for streets in any business or residence district is twenty-five miles per hour. The definitions of business and residence district are as follows:
235. A "business district" is that portion of a highway and the property contiguous thereto (a) upon one side of which highway, for a distance of 600 feet, 50 percent or more of the contiguous property fronting thereon is occupied by buildings in use for business, or (b) upon both sides of which highway, collectively, for a distance of 300 feet, 50 percent or more of the contiguous property fronting thereon is so occupied. A business district may be longer than the distances specified in this section if the above ratio of buildings in use for business to the length of the highway exists.
515. A "residence district" is that portion of a highway and the property contiguous thereto, other than a business district,
(a) upon one side of which 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, or
City of Santa Clarita Page 3
Engineering and Traffic Survey June 2023
(b) upon both sides of which 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. A residence district may be longer than one-quarter of a mile if the above ratio of separate dwelling houses or business structures to the length of the highway exists.
STATISTICAL ANALYSIS FACTORS
Significant factors used to analyze the collected survey data are summarized below:
1. 85th Percentile Speed. The critical speed, or 85th Percentile Speed, is defined as that speed at or below which 85 percent of the traffic is moving. This factor is the primary guide in determining what speeds the majority of safe and reasonable drivers are traveling.
Therefore, the practice is to set the speed limit to the nearest 5 mph increment from the Critical Speed unless other factors require a lower limit. Speed limits set on this basis provide law enforcement officials with a means of controlling reckless or unreliable drivers who will not conform to what the majority finds reasonable.
2. The 10-mph Pace. The 10-mph Pace is the 10-mph increment range, which contains the largest number of recorded vehicles. The pace is a measure of the dispersion of speeds within the sample surveyed. Speed limits should normally be set to fall within the 10 mph pace. However, conditions not readily apparent to the driver or adhering to State mandated limits such as in Residence Districts may require setting speed limits below the 10 mph pace.
3. 50th Percentile Speed. The Median Speed, or 50th Percentile Speed, represents the mid- point value within the range of recorded speeds for a particular roadway location. In other words, 50 percent of the vehicles travel faster than and 50 percent travel slower than, the median speed. This value is another measure of the central tendency of the vehicle speed distribution. Typically speed limits should not be set below the 50th Percentile Speed, since it would result in greater than 50-percent of the drivers exceeding the speed limit.
4. 15th Percentile. The 15th Percentile is that speed at or below which 15 percent of the vehicles are traveling. This value is important in determining the minimum allowable speed limit, given that the vehicles traveling below this speed tend to obstruct the flow of traffic, thereby increasing the collision potential.
5. Percent of Vehicles in Pace Speed. The percent of vehicles in the 10-mph pace speed is an indication of the grouping of vehicular speeds. Ideally, if all vehicles were traveling at or about the same speed, there would be a reduced likelihood of vehicular collisions. In speed limit analysis, the higher the percent of vehicles within the pace speed, the more favorable the speed distribution. The percent of vehicles within the 10-mph pace is often between 60 and 90 percent.

2014 CALIFORNIA MUTCD GUIDANCE BETWEEN ADJACENT
SEGMENTS
The State of California Traffic Manual previously published by the California Department of Transportation previously set guidance on the preparation of Engineering and Traffic Surveys.
Section 8-3.3 contained the guidance for establishing speed limits using an Engineering and Traffic Survey, and indicated that the speed limit should normally be established at the first five mile per hour increment below the 85th percentile speed. However, with the change to the 2014 California MUTCD, the guidance for establishing speed limits has been modified and the new requirements indicate:
“12a When a speed limit is to be posted, it shall be established at the nearest 5 mph increment of the 85th-percentile speed of free-flowing traffic, except as shown in the two Options below.
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.
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 85 th percentile speed, if no further reduction is used. Refer to CVC Section 21400(b).”
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 Section 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 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 85 th 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 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 85 th 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 reductions can be applied (which is allowed in the two examples above).”

Engineering and Traffic Survey June 2023
This change in the guidance for establishing speed limits was incorporated into the analysis and recommendation of speed limits for this study.
ASSEMBLY BILL 321
Existing law establishes a 25 miles per hour prima facie limit when approaching or passing a school building or the grounds thereof, contiguous to a highway and posted up to 500 feet away from the school grounds, 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 also applies when approaching or passing 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 and the highway is posted with a standard “SCHOOL” warning sign. A violation of that prima facie limit is an infraction.
Existing law allows a city or county, based on an engineering and traffic survey that the prima facie speed limit of 25 miles per hour is more than is reasonable or safe, by ordinance or resolution, to determine and declare a prima facie speed limit of 20 or 15 miles per hour, whichever is justified as the appropriate speed limit by that survey.
This bill additionally allows a city or county to establish in a residence district, on a highway with a posted speed limit of 30 miles per hour or slower, a 15 miles per hour prima facie limit when approaching, at a distance of less than 500 feet from, or passing, a school building or the grounds thereof, contiguous to a highway and posted with a school warning sign that indicates a speed limit of 15 miles per hour, while children are going to or leaving the school, either during school hours or during the noon recess period. The prima facie limit would also apply when approaching, at that same distance, or passing 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 and the highway is posted with one of those signs.
The bill also provides that a 25 miles per hour prima facie limit in a residence district, on a highway with a posted speed limit of 30 miles per hour or slower, applies, as to those local authorities, when approaching, at a distance of 500 to 1,000 feet from, one of those areas where children are going to or leaving the school, either during school hours or during the noon recess period, that is posted with a school warning sign that indicates a speed limit of 25 miles per hour.
ASSEMBLY BILL 43 (2021)
Assembly Bill 43, which modifies the California Vehicle Code to allow greater flexibility in setting speed limits, was signed by the Governor of California on October 8, 2021, and will go into effect on January 1, 2022. The bill primarily modifies Section 22358 of the California Vehicle Code to add the follow subsections:
· Section 22358.7
o This subsection allows for a local agency to reduce a speed limit a further 5 miles per hour from what is required by the 85th percentile speed, if the roadway is designated City of Santa Clarita Page 6
Engineering and Traffic Survey June 2023
as a “safety corridor” or if the roadway is adjacent to land uses that generate high concentrations of bicyclists and pedestrians.
o The definitions of “safety corridors” and the determination of the land uses that generate high concentrations of bicyclist and pedestrians are underway. As such, local authorities may not lower speed limits using this section until June 30, 2024. o After June 30, 2024, the City of Santa Clarita may lower speed limits on segments designated as “safety corridors”.
· Section 22358.8
o This subsection allows a local agency to retain a current speed limit or restore the immediately prior speed limit if that agency finds that the speed limit required by the 85th percentile speed is more than reasonable or safe. A registered engineer must evaluate the roadway to determine that no additional general purpose lanes have been added since the previous speed limit was established
o This section does not authorize a speed limit to be reduced by any more than five miles per hour from the current speed limit nor below the immediately prior speed limit.
o A local authority shall issue only warning citations for violations of exceeding the speed limit by 10 miles per hour or less for the first 30 days that a lower speed limit is in effect as authorized by this section.
· Section 22358.9
o This subsection allows a local agency to set a prima facie speed limit of either 20 or 25 miles per hour on roadways contiguous to a “Business Activity District”. Speed limit signs must be posted on these roadways. This applies to roadways that meet the following conditions:
§ Road has maximum of 4 lanes
§ If establishing a 25 mile per hour prima facie speed limit, there must be a maximum 30 mile per hour speed limit immediately prior to and after the roadway section
§ If establishing a 20 mile per hour prima facie speed limit, there must be a maximum 25 mile per hour speed limit immediately prior to and after the roadway section
o Roadways in a “Business Activity District” must meet 3 out of the following 4 requirements:
§ No less than 50 percent of the contiguous property fronting the highway consists of retail or dining commercial uses, including outdoor dining, that open directly onto sidewalks adjacent to the highway.
§ Parking, including parallel, diagonal, or perpendicular spaces located alongside the highway.
§ Traffic control signals or stop signs regulating traffic flow on the highway, located at intervals of no more than 600 feet.
§ Marked crosswalks not controlled by a traffic control device.

· Section 22358.10
o This subsection allows for the declaration of ‘senior zones’, defined as an “that area approaching or passing a senior center building or other facility primarily used by senior citizens, or the grounds thereof that is contiguous to a highway.” o Lower prima facie speed limits are allowed in ‘senior zones’ where a “SENIOR” warning sign is posted.
Kimley-Horn has determined that the following segment can retain its previous speed limit per California Vehicle Code Section 22358.8, as amended by Assembly Bill 43.

FIELD REVIEW
Kimley-Horn conducted the speed survey on street segments as requested. The consultant’s team inspected all street segments for traffic related concerns, including visibility, driveways, existing land use and road conditions not readily apparent to motorists.
Examples of the field data collected for the purposes of analyzing related roadway characteristics as they pertain to the determination of appropriate speed limits are listed below:
1. Segment length, width and alignment;
2. Level of pedestrian and bicycle activity;
3. Traffic flow characteristics;
4. Number of lanes and other channelization/striping factors;
5. Frequency of intersections, driveways and on-street parking;
6. Locations of stop signs, traffic signals, and other regulatory traffic control devices;
7. Roadway condition, bumps and dips;
8. Obstructions to driver/pedestrian visibility;
9. Land use and proximity of schools;
10. Uniformity with existing speed zones in adjacent jurisdictions; and,
11. Any other unusual conditions or hazards not readily apparent to the driver.
COLLISION HISTORY
The Engineering and Traffic Survey forms summarize the available collision information for each of the street segments. The summary of collision data was obtained for a period of three years. The related collisions, including were summarized for each segment. Based on the number of total collisions studied over the 24-month period (January 1 st, 2021 to December 31st, 2022) and ADT counts collected by Kimley-Horn, a collision rate per million vehicle miles was calculated for each segment. To provide a general comparison of the collision rates on the segments to expected City of Santa Clarita Page 8
Engineering and Traffic Survey June 2023
collisions rates for similar types of local roadways, the collision rates for each segment were compared to the statewide average rate listed in the 2020 Collision Data on California State Highways (road miles, travel, collisions, collision rates) as listed inTable 1. Collision rates higher than expected can be used as justification.

RESULTS AND RECOMMENDATIONS
Roadway conditions such as width, number of lanes, traffic control devices, and properly identified schools are readily apparent to the driver and should not influence the results of the Engineering and Traffic Survey.
The recommendations contained in this report are intended to establish prima facie speed limits.
Prima facie limits attempt to advise the motorist and enforcement of the reasonable speed for a particular section of roadway for the prevailing conditions. In many cases, the recommendations may produce a uniform speed limit along the road.
The radar speed survey results, as collected by Counts Unlimited, are shown in Appendix A. The Engineering and Traffic Survey Sheets, presented in the Appendix B, illustrate the results of a thorough evaluation of the available data and indicate a recommended speed limit for each of the street segments surveyed.
T a b l e 2 below indicates the recommended changes to speed limits on each segment that was surveyed. Appendix C contains a summary sheet that has illustrates the factors that informed the recommendations for each segment.
