Review and consideration to waive full reading of and
introduce AN ORDINANCE OF THE CITY OF CERRITOS
AMENDING CHAPTER 10.04, SPEED LIMITS, OF THE

CERRITOS MUNICIPAL CODE TO UPDATE PRIMA FACIE

SPEED LIMITS ON CERTAIN STREETS IN THE CITY OF
CERRITOS.

The City of Cerritos is required to conduct speed surveys on arterial streets to evaluate existing posted speed limits and determine whether adjustments are warranted. To establish speed limits, the City follows the State of California established procedure, which considers the legal requirements outlined in Sections 40802 and 22352 - 22366 of the California Vehicle Code (CVC), as well as speed zoning guidelines contained in the 2026 California Manual on Uniform Traffic Control Devices (MUTCD).

Speed limits are defined in two primary categories: maximum speed limits and prima facie speed limits. Prima facie speed limits are considered reasonable and prudent under normal conditions. Prima facie speed limits come in two categories: (i) blanket or automatic speed limits established in the eve (including 15 mph in alleys and 25 mph in residential and business districts and school areas); and (ii) intermediate prima facie speed limits of between 25 mph and 65 mph, established by prevailing conditions.

The 85th percentile speed is the main characteristic of travel that most nearly corresponds to a safe and reasonable speed limit. The 85th percentile speed is generally used as the primary indicator of a reasonable speed limit because it represents the speed at or below which approximately 85 percent of observed vehicles are traveling.

For practical purposes, the 5-mph increment at or immediately below the 85th percentile is the numerical value properly selected for posting a realistic and enforceable speed limit. However, for special situations with high accident rates, highway alignment or traffic and roadside conditions not readily apparent to a driver, a further 5-mph reduction in the speed limit may be justified.

CMC Amendment - Chapter 10.04 Speed Limits
September 28, 2026

As defined in the CVC, an Engineering and Traffic Survey is a survey of highway and traffic conditions undertaken with methods and procedures outlined in the MUTCD. The engineering survey includes a consideration of (a) prevailing speeds as determined by traffic engineering speed measurements, (b) collision records, and (c) highway, traffic and roadside conditions not readily apparent to the driver. After the completion of a speed survey, the data are tabulated and the average speed and the 85th percentile speed (critical speed or speed limit speed) for each roadway segment are calculated.

The 85th percentile speed is the speed which 85% of the observed vehicles are not exceeding.

State law permits local authorities to establish speed limits by lowering the maximum speed limit of 65 mph or raising business and residence district speed limits above 25 mph by ordinance on the basis of a supportive Engineering and Traffic Survey. These intermediate limits between 25 and 65 mph must be posted to clearly define the limits of the speed zone and the maximum allowed speed.
eve Section 40802 specifies that prima facie speed limits established under Sections 22352 (a), 22354, 22357, 22358 and 22358.3 may not be enforced by radar unless the speed limit has been justified by an Engineering and Traffic Survey. Existing prima facie speed limits on Cerritos arterial streets were approved in April 2013 by City Council Ordinance No. 974 following the preparation of an Engineering and Traffic Survey. In April 2018, the City Council adopted Resolution No. 2018-06, which approved the findings of a 2018 Engineering and Traffic Survey. The 2018 Engineering and Traffic Survey concluded that all speed limits previously established by Ordinance and contained within Title 10, Chapter 10.04 of the Cerritos Municipal Code remain unchanged and in effect.

ANALYSIS
In August 2025, the City's on-call traffic consultant, Hartzog & Crabill, Inc., commenced the preparation of an updated Engineering and Traffic Survey for arterial streets in the City of Cerritos (Exhibit 6 - Engineering and Traffic Survey for Speed Limits). The survey includes radar speed surveys, collision data analysis from the California Statewide Integrated Traffic Records System (SWITRS), and field review by a registered Traffic Engineer at ninety (90) roadway locations throughout the City.

In July 2026, the Engineering and Traffic Survey was completed and determined that existing speed limits on a majority of the arterial streets within the City of Cerritos should remain unchanged. However, in select roadway segments throughout the City, speed limit reductions are recommended based on factors identified in the survey, including Safety Corridor designations, concentrations of pedestrian and bicyclist users, collision history, roadway conditions, and consistency with adjacent speed zones. Based on the traffic speed data, it is recommended that the speed limits on these segments be reduced and that new speed limit signs be installed in both directions to reflect the revised limits and enhance enforcement.

The proposed speed limit reductions include a total of twenty-six {26) segments on arterial streets. This includes eleven (11) street segments where the speed limit would be reduced from 45 mph to 40 mph, fourteen (14) street segments where the speed limit would be reduced from 40 mph to 35 mph, and one (1) street segment where the speed limit would be reduced from 35 mph to 30 mph. The recommended speed limit 33 CMC Amendment - Chapter 10.04 Speed Limits
September 28, 2026

reductions and corresponding roadway locations are identified in Exhibit 4 - Engineering and Traffic Survey Recommendations and Exhibit 5 - Engineering and Traffic Survey Map. PROPOSED MODIFICATIONS TO THE MUNICIPAL CODE
Section 10.04 of the Cerritos Municipal Code establishes speed limits on arterial streets within the City of Cerritos (Exhibit 2 - Existing Regulations - Chapter 10.04 - Speed Limits). Specifically, it outlines prima facie speed limits on the City's arterial streets of:
45, 40, 35, and 30 miles per hour. As noted in the analysis section of this report, the Engineering and Traffic Survey recommends that speed limits on select roadway segments be reduced. The proposed modifications to Section 10.04 are provided in Exhibit 3 (See Exhibit 3 - Proposed Modifications - Chapter 10.04 - Speed Limits).

FISCAL IMPACT
Should the ordinance be adopted, new speed limit signage would be required to be installed at approximately 90 locations. The total cost of the new or replacement speed limit signage is estimated to be $7,000 and will be funded through Fiscal Year 2026- 2027 Capital Improvement Program, Citywide Speed and Traffic Study, Project No. 27302. The approved Fiscal Year 2026-2027 Combined Financial Program includes General Fund appropriations sufficient to cover the cost of the proposed sign replacement.

RECOMMENDATION
Staff recommends the following to the City Council:

1. Waive full reading of and introduce an ordinance amending Chapter 10.04 of the Cerritos Municipal Code set forth in the proposed ordinance, captioned:

ENGINEERING AND TRAFFIC SURVEY FOR SPEED LIMITS
Introduction
In accordance with procedures established by the State of California, this Engineering and Traffic Survey (E&TS) has been developed for the City of Cerritos as the basis for the establishment and enforcement of speed limits for selected streets within the City. The work provided herein was authorized by the City and was performed by the engineering consulting firm of Hartzog & Crabill, Inc. The goal of the review was two-fold. The first was to review new roadway segments to determine if speed limit postings should be recommended. The second involved a determination as to whether changes in pre-existing conditions have occurred where older speed limits should be modified.

The requirement to perform E&TS for speed limits is based on the California Vehicle Code (CVC).

Section 40802 states that at least once every five (5), seven (7), or 14 years, States and local agencies should re-evaluate non-statutory speed limits on segments of their roadways. E&TS must be performed with the use of radar or other approved electronic devices if the use of radar is to be employed to enforce speed limits. If such a survey is not performed within five (5), seven (7) years, or 14 years as stated previously of the date of the preceding survey, then the new data and its use will constitute a "speed trap". Hence, evidence using such would not be admissible in court.

The definition of an E&TS is contained in Section 627 of the CVC and is as follows:

E&TS, as used in this code, means a survey of highway and traffic conditions in accordance with methods determined by the California Department of Transportation (Caltrans) for use by State and local authorities. An E&TS shall include, among other requirements deemed necessary by the department, consideration 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.

The CVC has set certain regulations regarding the posting and enforcement of speed zones. These regulations generally reflect the viewpoint that speed zoning should be based on traffic conditions and natural driver behavior and not because of an arbitrary response to a traffic event or occurrence. Therefore, it is important to have a general understanding of the "Basic Speed Law", "Prima Facie Speed Limits" and "Intermediate Speed Zones".

Basic Speed Law (CVC 22350)
All fifty states base their speed regulations on the Basic Speed Law. In California, CVC 22350 defines the basic speed law as:
"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." 16 2
This law recognizes that driving conditions vary widely from time-to-time and place-to-place and, therefore, no set of fixed driving rules will adequately serve all conditions. The motorist will constantly adjust their driving behavior to fit the conditions encountered and must learn to do this with a minimum of assistance from the police. The Basic Speed Law is founded on the belief that a majority of motorists are able to modify their driving behavior properly, as long as they are aware of the conditions around them.

Prima Facie Speed Limits (CVC 22352)
All other speed limits are prima facie limits which, "on the face of it", are reasonable and prudent under normal conditions. The opportunity given to the driver to exceed a prima facie speed limit when it is safe to do so recognizes the fact that any posted speed limit cannot adequately reflect the many different conditions of traffic, weather, visibility, etc., that may be found on the same highway at different times.

Certain prima facie limits are automatically established by law (CVC 22352), including a 15 miles per hour (mph) limit in alleys, blind intersections, blind railroad crossing, and the 25 mph limit in business and residence districts. There is also a part time 25 mph limit in school zones when children are present on the route to or from school.

Business and residence districts are defined in the CVC as specific areas meeting a specified minimum density of roadside development. CVC Sections 235 and 515 define these regulations.

A count of houses or active businesses facing on a highway must be made to determine whether or not a valid business or residence district exists. The law does not require posting these prima facie limits that are readily apparent.

Business District (CVC 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 business in use for business to the length of the highway exists.

Residence District (CVC 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 (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.
17 3
Assembly Bill 43
In accordance with Assembly Bill (AB) 43, it established to two (2) new categories for consideration where it may be appropriate to reduce the speed limit by 5 mph. These were codified as CVC 22358.7 as explained in further detail below. The first category is for a street to be designated as a Safety Corridor, and the second category is for a street to be designated as a street with high concentrations of bicyclists and/or pedestrians. Based on the CVC, it should be noted that two (2) new categories cannot be applied to Caltrans State highways Safety Corridor (CVC 22358.7(a)(1))
The California Manual on Uniform Traffic Control Devices (CA MUTCD) defines a Safety Corridor to be a street where the highest number of fatalities and/or serious injury collisions occurs over a period of three (3) to five (5) years. Safety Corridors are limited to 20 percent of City maintained streets. Therefore, it may be appropriate that certain collisions involving vulnerable populations (i.e., children, seniors and persons with disabilities) are weighted more in order to prioritize which streets get the Safety Corridor designation. Streets designated as Safety Corridors may have the speed limit reduced by 5 mph.

High Pedestrian & Bike Users (CVC 22358.7(a)(2))
Based on the CA MUTCD, streets that have facilities that generate high concentration of pedestrian and bike users may have the speed limit reduced by 5 mph. Examples of these facilities include schools, parks, medical facilities, religious centers and shopping centers. It is important to note that only the portion within 1,320 feet of these types of facilities would qualify for the 5 mph speed reduction. In accordance with the CA MUTCD, an acceptable alternative to high concentration of pedestrian and bike users is to identify the streets within the top 20 percent of fatalities and/or serious injuries collisions involving pedestrians and/or bicyclists over a period of three (3) to five (5) years.

Establishment of Speed Zones
The reason that speed limit areas and their required postings are done is to guard reasonable drivers from the unreasonable behavior of reckless, unreliable, or otherwise dangerous drivers. As with other similar laws, the limits identified are based on the consensus of the majority of those who drive the highway as to what speed is reasonable and safe. It is this type of information that is reflected in the analysis section of this report. Namely, posted speed limits are a reflection of that speed which most people deem to be safe as opposed to a minority of drivers who do not drive in a reasonable manner.

Speed zones are also established to advise of road conditions or hazards that may not be readily apparent to a reasonable driver. For that reason, a field review of related road/traffic variables is conducted which considers the analytical data and collision history of a particular roadway segment to determine a safe and reasonable speed limit. 18 4
Data Collection Procedures
Speed evaluation data was collected at 90 different segments on 21 different roadways in the City of Cerritos. These areas and the number of segments on each are described as follows:

1. Artesia Boulevard (8) 8. Marquardt Avenue (4) 15. South Street (8)

2. Bloomfield Avenue (7) 9. Norwalk Boulevard (4) 16. Studebaker Road (6)

3. Carmenita Road (5) 10. Palo Verde Avenue (2) 17. Towne Center Drive (1)

4. Del Amo Boulevard (4) 11. Park Plaza Drive (2) 18. Valley View Avenue (2)

5. Dumont Avenue (1) 12. Pioneer Boulevard (3) 19. 166th Street (9)

6. Edwards Road (1) 13. Piuma Avenue (1) 20. 183rd Street (7)

7. Gridley Road (5) 14. Shoemaker Avenue (5) 21. 195th Street (5) As described in various traffic engineering documents - including information provided by the State of California, the individual locations on which radar data collection procedures used involved considerations for the following:
a. Stop sign or traffic signal locations;
b. Visibility issues;
c. Traffic flow at intersections, cross-traffic, major driveways, crosswalks, railroad crossings and unusual turning movements;
d. The influence of other traffic factors on the speed of cars: such as on street parking, roadway features, adjacent land uses, and lighting.

Speed Zoning Methodology
The CA MUTCD specifies a "short method" of determining speed limits on City and County through Highways, Arterial and Collector Roads Procedures. This short method of speed zoning is based on the premise that the reasonable speed limit is one that conforms to the actual behavior of the majority of motorists, and that by measuring motorist 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, super-elevation, shoulder conditions, profile conditions, intersection spacing and offsets, commercial driveway characteristics, pedestrian traffic in the roadway without sidewalks.

Speed Zone Survey
- Only one person is required for the fieldwork. Speeds can be read directly from a radar speed meter.
- A section of road should be selected with representative operating speeds. If speeds vary on a given road, additional surveys should be conducted. In this case, it may be necessary to establish additional speed zones with different speed limits.
- Speed measurements should be taken during off-peak hours on weekdays. The weather should be fair with no unusual conditions prevailing. It is important that the surveyor and his equipment be so inconspicuous as not to affect traffic speeds. For this reason, an unmarked car is recommended, 19 5
with the radar speed meter located as inconspicuously as possible. It should be placed so as to be able to survey traffic in both directions, and should not make an angle greater than 15 degrees with the roadway center line.

- It is desirable to have a minimum sample of 100 automobiles in each survey. This may result in excessive survey periods for low-volume roads. Under these conditions, the survey should be conducted for a minimum of two hours, but in no case should the sample for any survey contain less than 50 automobiles.
- The CA MUTCD states that speed limits are established at or near the 85th percentile speed, which is defined as that speed at or below which 85 percent of the traffic is moving. This speed can be selected directly from the data sheet. However, roadway conditions not readily apparent to the motorist or other roadway conditions that may impact sight distance may result in a further reduction of 5 mph in the recommended speed limit.
- As a check on the validity of the proposed speed limit, an analysis should be made of the fiveyear collision record for the section of roadway under consideration. If this record shows an abnormally high percentage of collisions normally associated with excessive speeds, the proposed speed limit should be further reduced. This is a judgement situation, and will not usually be a factor,
- Short speed zones of less than half a mile should be avoided, except in transition areas. - Speed zone changes should be coordinated with changes in roadway conditions or roadway development.
- Speed zoning should be coordinated between adjacent jurisdictions.

Local Street Exemptions (CVC 40802)
Many streets are designated as "Local" streets per CVC 40802. These streets are exempt from the radar study. Therefore, the speed limit for these streets does not require an E&TS. The code is as follows:
"For the purpose of this section, local streets and roads shall be defined by the latest functional usage and federal aid system maps as submitted to the Federal Highway Administration. When these maps have not been submitted, the following definition shall be used: A local street or road primarily provides access to abutting residential property and shall meet 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.

Other Considerations
Every street should be inspected for unusual traffic, roadway and roadside conditions not readily apparent to a motorist. A check should be made of the adequacy of traffic control devices, 20 6
roadway alignment, width surface conditions, collision history and any unique traffic hazards that may exist. Any of these conditions may warrant the selection of a speed lower than the 85th percentile speed for speed zoning.

Radar Collection Time-Frames
The hours of radar operation were restricted to off-peak periods (when possible) for heavily traveled streets and to uncongested peak periods on lightly traveled streets. All surveys were conducted in fair weather.

The radar unit was mounted at the top of the front dash of an unmarked vehicle with the meterreading unit sustained inside the vehicle. The radar unit's calibration was checked periodically using a tuning fork.

The radar operator and assistant recorded the speed meter readings for each location on Radar Speed Survey Field Sheets included in the appendix of this report. A representative sampling of at least 100 vehicles were surveyed.

Analysis Factors
Several factors were used as input to our recommendations for speed limits. These include the 85th Percentile, the 10 MPH Pace and others. These are described in detail below.

1. The CRITICAL SPEED, or the 85th percentile, is defined as that speed at or below which 85 percent of the traffic is moving. From experience, traffic engineers have found that this is one of the most reliable factors in determining appropriate speed limits.

Hence, the accepted practice, and one that has been used in this case is to set the speed limit at or near the critical speed. This recognizes that other factors could be present where the above may not be appropriate. When this procedure is used, it not only conforms to that required by the State but it also provides a strong base for law enforcement personnel to properly enforce speed limits.

2. The 10 MPH PACE is that continuous 10 mph incremental range of speeds in which the largest number of recorded vehicles is contained. It is a measure of the dispersion of speeds within the sample surveyed. For this element, the accepted practice to the greatest extent possible is to try and keep the recommended speed limit within the 10 mph pace after considering the critical speed and any factors requiring a speed lower than the critical speed.

3. The MEDIAN (MIDDLE) 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% of the vehicles travel faster than the median speeds and 50% travel slower than the median speeds. This value is another measure of the central tendency of the vehicle speed distribution.

4. The 15th PERCENTILE SPEED is that speed at or below which 15% of the vehicles are traveling. This value is important in determining the minimum allowable speed limit, given that the vehicles traveling below this speed tend to obstruct the flow of traffic, thereby increasing the collision potential.
21 7

5. MODAL SPEED: The modal speed is the speed, which occurs most frequently in the distribution (the most). It serves as another useful measure in verifying the correct recommendation for speed limits.

6. STANDARD DEVIATION: This is a mathematical element, which relates to measures of dispersion of data. It is used to assist in describing the center of speed distribution information around the arithmetic mean or the time mean speed. It also is used in the overall review of recommended speed limits and serves to verify the level of confidence of data used in making recommendations.

7. The MEAN (AVERAGE) is the sum of the speeds of the samples divided by the number of samples.

The numerical values of the above factors are derived from the speed distribution curves calculated for each survey location. These distribution curves represent a method of graphic analysis that compares the cumulative percentage of vehicles to the speed at which the vehicles are traveling.

Field Review
In addition to the availability of the above statistical data, a significant aspect of speed limit recommendations is based on the field review. Its importance is that existing conditions may warrant a lower speed than is actually indicated by the application of survey data. 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 as follows:

1. Segment length, width and alignment

2. Level of pedestrian activity

3. Traffic flow characteristics

4. Vertical and/or horizontal curves.

5. Driver sight distance constraints.

6. Adjacent residential/commercial/industrial etc. zoning.

7. Number of lanes and other channelization/striping factors

8. Frequency of intersections, driveways and on street parking;

9. Location of stop signs, traffic signals, and other regulatory traffic control devices;

10. Roadway conditions, bumps and dips;

11. Obstructions to pedestrian visibility;

12. Land use and proximity of schools;

13. Uniformity and continuity with existing speed zones to/with adjacent jurisdictions;

14. Any other unusual conditions not readily apparent to the driver.

The results of the field review of related road/traffic variables are summarized on the E&TS forms found in the Appendix of this report.

Collision History
The E&TS forms summarize the available five-year collision information for the subject streets.

The collision information includes the total number of collisions within each street segment and of those collisions, the number that are speed-related, involved fatalities, serious injuries, pedestrians 22 8
and bicyclists. This information was obtained from the California Statewide Integrated Traffic Records System (SWITRS) for the City of Cerritos. To provide an equitable comparison between street segments the collision data was converted to collisions per million vehicle miles.

Results and Recommendations
The following Summaries: Safety Corridor analysis, No Speed Limit Changes, New Speed Limit Postings, Speed Limit Reductions and Summary of Recommendations, present the results of the radar survey for the selected 90 locations. As shown, the Summary of Recommendations chart presents the necessary analysis elements that in addition to the field review of a registered Traffic Engineer led to the recommendations indicated.

Safety Corridor Analysis
In accordance with the CVC and CA MUTCD, the Safety Corridor designation is limited to 20 percent of City maintained streets. In the City of Cerritos, there are approximately 142 miles of City maintained streets. These do not include private streets that are maintained by the various Homeowner Associations. A maximum of 28.4 miles of City streets can be designated as a Safety Corridor. Based on an analysis of all 90 street segments, collision history and street prioritization, the 21 segments in the Table below are recommended to be designated as Safety Corridors.

Collectively, the Safety Corridors have a total of 10.04 miles, which is less than 28.4 miles.

Locations of “Residence District”
One roadway segment listed for the E&TS fall under the CVC Section 515, “Residence District Speed Limit.” Explanations and requirements for Residence District are on Page 2. The CVC states that prima facie roadways are not required to be posted. Therefore, the City may choose to remove existing speed signs or leave them alone. These roadway segments are listed below:

Gridley Road
195th St to Mapes Ave Establish as Residence District – 25 mph Support Explanations for “Residence District”
Gridley Road
31 – 195th Street to Mapes Avenue
This section of Gridley Road is a two-lane residential roadway. The speed data resulted with an 85th percentile speed of 32.2 mph that initially suggests a 30 mph posting. The need to retain the CVC defined lower speed is based on (A) 28 single-family dwellings with direct access driveways between 195th Street to Bertha Street (0.19 mi) and, (B) 22 single-family dwellings with direct access driveways between Yealing Street to Mapes Avenue (0.18 mi). This segment meets the requirement for the CVC 515 "Residence District". Therefore with all these factors, it is recommended that the City establish the segment of Gridley Road a Residence District". This segment does not require continued speed surveys.

Locations of “No Speed Limit Changes”
The Summary indicates that 55 of the 90 segments studied are recommended for no speed limit changes. The reason centers mostly on the fact that the newly measured values of the 85th percentile and the 10 MPH pace are still within the parameters of the existing speed limits. Additional factors such as reduced sight distance, higher than expected collision rates, high pedestrian and bicyclist traffic, areas that are considered as a safety corridor, and keeping continuity with the speeds of neighboring segments form the basis in some instances of our recommendation. Therefore, the current postings should remain as is. At 19 of these locations, only one direction of travel is posted and is listed for no change in the speed limit. Hence, the other direction should be posted for consistency. The segments for “No Speed Limit Changes” are listed below:

Support Explanations of “No Speed Limit Changes”
The following support explanations are for the roadway segments recommended to maintain the existing posted speed limits and that are 5 mph or more lower than the newly measured 85th percentile speed.

Bloomfield Avenue
9 – 200’ s/o Alondra Boulevard to 166th Street
This section of Bloomfield Avenue is a four-lane roadway. Currently, the speed limit is 40 mph.

The adjacent land uses are residential, commercial and business-industrial. The speed study resulted with an 85th percentile speed of 45.2 mph and a 10 mph range of 36 to 45 mph. In an effort to keep consistency with the speed limits of the adjacent segments, it is recommended that the existing 40 mph speed limit remain.
26 12
Del Amo Boulevard
22 – Pioneer Boulevad to Norwalk Boulevard
This section of Del Amo Boulevard is a four-lane roadway. Currently, this segment has a 40 mph speed limit posted for the westbound direction only. The adjacent land uses are residential (non-fronting), church, Artesia High School, adult school, and commercial. The speed study results show an 85th percentile speed of 45.6 mph which may suggest a 45 mph speed limit. A review collision history revealed that this segment had 11 speed related collisions and two (2) collisions involved serious injuries, which ranked it as one of the top locations in the City that involved fatality and/or serious injury collisions. In accordance with CVC 22358.7 (a)(1), this segment is designated as a "Safety Corridor" which allows the speed limit to be reduced by 5 mph.

Therefore, it is recommended to maintain the existing 40 mph speed limit and to be installed in the eastbound direction.
23 – Norwalk Boulevard to Bloomfield Avenue
This section of Del Amo Boulevard is a four-lane roadway. The adjacent land uses are residential single & multi-family (non-fronting), church, and middle school. The speed study results show an 85th percentile speed of 45.3 mph which may suggest a 45 mph speed limit. A review collision history revealed that this segment had eight (8) speed related collisions and three (3) collisions involved serious injuries, which ranked it as one of the top locations in the City that involved fatality and/or serious injury collisions. In accordance with CVC 22358.7 (a)(1), this segment is designated as a "Safety Corridor" which allows the speed limit to be reduced by 5 mph. Therefore, it is recommended to maintain the existing 40 mph speed limit. 24 – Bloomfield Avenue to Denni Street
This section of Del Amo Boulevard changes from one (1) lane to two (2) lanes then one (1) lane per direction. The adjacent land uses are residential (non-fronting), park, and commercial.

In accordance with CVC 22358.7 (a)(1), this segment is designated as a "Safety Corridor" which allows the speed limit to be reduced by 5 mph. Therefore, it is recommended to reduce the existing 40 mph speed limit to 35 mph. 37 23

This section of Artesia Boulevard is a four lane roadway. The adjacent land uses are residential (non-fronting), and commercial.

The speed study results show an 85th percentile speed of 46.3 mph which may suggest a 45 mph speed limit. A review collision history revealed that this segment had 7 speed related collisions, 3 collisions involved serious injuries, 2 collisions involved pedestrians, and 1 collision involved a bicyclist(s), which ranked it as one of the top locations in the City that involved fatality and/or serious injury collisions. In accordance with CVC 22358.7 (a)(1), this segment is designated as a "Safety Corridor" which allows the speed limit to be reduced by 5 mph. Collectively, this segment and other City streets designated as a "Safety Corridor" did not exceed more than 20% of City maintained streets. Therefore, it is recommended to reduce the existing 45 mph speed limit to 40 mph.

This section of Artesia Boulevard is a four lane roadway. The adjacent land uses are residential (non-fronting), commercial, and business-industrial. The speed study results show an 85th percentile speed of 46.7 mph which may suggest a 45 mph speed limit.

A review collision history revealed that this segment had 3 speed related collisions, 3 collisions involved serious injuries, and 1 collision involved pedestrians, which ranked it as one of the top locations in the City that involved fatality and/or serious injury collisions. In accordance with CVC 22358.7 (a)(1), this segment is designated as a "Safety Corridor" which allows the speed limit to be reduced by 5 mph. Collectively, this segment and other City streets designated as a "Safety Corridor" did not exceed more than 20% of City maintained streets. Therefore, it is recommended to reduce the existing 45 mph speed limit to 40 mph.

This section of Bloomfield Avenue is a four lane roadway. The adjacent land uses are residential (non-fronting), commercial, business, Heritage Park, and Cerritos High School. The speed study results show an 85th percentile speed of 41.6 mph which may suggest a 40 mph speed limit. However, in accordance with CVC 22358.7(a)(2), this segment is designated as a street with “high concentrations of pedestrian and bike users” which allows the speed limit to be reduced by 5 mph. For the entire stretch of this segment, there are schools or parks within a distance of 1,320 feet. Therefore, it is recommended that the existing 40 mph speed limit be reduced to 35 mph.

This section of Bloomfield Avenue is a four lane roadway. The adjacent land uses are residential (non-fronting), and commercial.

The speed study results show an 85th percentile speed of 43.0 mph which may suggest a 40 mph speed limit. A review collision history revealed that this segment had 1 speed related collision, 2 collisions involved serious injuries, and 1 collision involved pedestrians, which ranked it as one of the top locations in the City that involved fatality and/or serious injury collisions. In accordance with CVC 22358.7 (a)(1), this segment is designated as a "Safety Corridor" which allows the speed limit to be reduced by 5 mph. Collectively, this segment and other City streets designated as a "Safety Corridor" did not exceed more than 20% of City maintained streets. Therefore, it is recommended to reduce the existing 40 mph speed limit to 35 mph and post northbound.

* 25 MPH WHEN CHILDREN PRESENT, SCHOOL ZONE
This section of Carmenita Road is a four lane roadway. The adjacent land uses are residential (non-fronting), school, and businessindustrial. The speed study results show an 85th percentile speed of 48.1 mph which may suggest a 45 mph speed limit. A review collision history revealed that this segment had 6 speed related collisions, and 2 collisions involved serious injuries, which ranked it as one of the top locations in the City that involved fatality and/or serious injury collisions. In accordance with CVC 22358.7 (a)(1), this segment is designated as a "Safety Corridor" which allows the speed limit to be reduced by 5 mph. Collectively, this segment and other City streets designated as a "Safety Corridor" did not exceed more than 20% of City maintained streets. Therefore, it is recommended to reduce the existing 45 mph speed limit to 40 mph.

This section of Carmenita Road is a four lane roadway. A 45 mph speed limit sign is posted in the southbound direction only and 25 mph when children present signs. The adjacent land uses are residential (non-fronting), an elementary school, and commercial.

The speed study results show an 85th percentile speed of 46.8 mph which may suggest a 45 mph speed limit. A review collision history revealed that this segment had 4 speed related collisions, 1 collision involved serious injuries, and 1 collision involved a pedestrian, which ranked it as one of the top locations in the City that involved fatality and/or serious injury collisions. In accordance with CVC 22358.7 (a)(1), this segment is designated as a "Safety Corridor" which allows the speed limit to be reduced by 5 mph.

This section of Carmenita Road is a four lane roadway. A 45 mph speed limit sign is posted in the southbound direction only. The adjacent land uses are residential (non-fronting), and commercial. The speed study results show an 85th percentile speed of 46.4 mph which may suggest a 45 mph speed limit. A review collision history revealed that this segment had 6 speed related collisions, and 2 collisions involved serious injuries, which ranked it as one of the top locations in the City that involved fatality and/or serious injury collisions. In accordance with CVC 22358.7 (a)(1), this segment is designated as a "Safety Corridor" which allows the speed limit to be reduced by 5 mph. Collectively, this segment and other City streets designated as a "Safety Corridor" did not exceed more than 20% of City maintained streets. Therefore, it is recommended to reduce the existing 45 mph speed limit to 40 mph and post northbound.

NF = NON-FRONTING File: Del Amo 2025-22
This section of Del Amo Boulevard is a four lane roadway. The adjacent land uses are residential (non-fronting), church, Artesia High School, adult school, and commercial. The speed study results show an 85th percentile speed of 45.6 mph which may suggest a 45 mph speed limit. A review collision history revealed that this segment had 11 speed related collisions, and 2 collisions involved serious injuries, which ranked it as one of the top locations in the City that involved fatality and/or serious injury collisions. In accordance with CVC 22358.7 (a)(1), this segment is designated as a "Safety Corridor" which allows the speed limit to be reduced by 5 mph. Collectively, this segment and other City streets designated as a "Safety Corridor" did not exceed more than 20% of City maintained streets. Therefore, it is recommended to maintain the existing 40 mph speed limit and post eastbound.

NF = NON-FRONTING File: Del Amo 2025-24
This section of Del Amo Boulevard changes from 1 lane to 2 lanes then 1 lane per direction. The adjacent land uses are residential (non-fronting), park, and commercial. The speed study results show an 85th percentile speed of 45.4 mph which may suggest a 45 mph speed limit. A review collision history revealed that this segment had 3 speed related collisions, 1 collision involved a fatality, 1 collision involved serious injuries, and 1 collision involved a pedestrian, which ranked it as one of the top locations in the City that involved fatality and/or serious injury collisions. In accordance with CVC 22358.7 (a)(1), this segment is designated as a "Safety Corridor" which allows the speed limit to be reduced by 5 mph. Collectively, this segment and other City streets designated as a "Safety Corridor" did not exceed more than 20% of City maintained streets. Therefore, it is recommended to maintain the existing 40 mph speed limit and post westbound.

File: Dumont 2025-25
This section of Dumont Avenue is a two lane roadway. The posted speed limit is 35 mph. The adjacent land uses include car dealership at 183rd Street, horse stables, high school & middle school, parking lot across the street of the schools. Field notes state that there are 3 school crossings mid- block in front of the schools, heavy pedestrians at drop off + pickups, and many pedestrians cross the street to parking lot on west-side the street. The speed study results show an 85th percentile speed of 34.6 mph and a median speed of 30.6 mph. However, in accordance with CVC 22358.7(a)(2), this segment is designated as a street with “high concentrations of pedestrians and bike users”, which allows the speed limit to be reduced by 5 mph. For entire stretch of this segment, there are two schools that encompass the majoring of the area. Therefore, it is recommended to reduce the existing 35 mph speed limit to 30 mph.

F = FRONTING File: Gridley 2025-31
This section of Gridley Road is a two lane residential roadway. The speed data resulted with an 85th percentile speed of 32.2 mph that initially suggests a 30 mph posting. The need to retain the CVC defined lower speed is based on (1) 28 single-family dwellings with direct access driveways between 195th Street to Bertha Street (0.19 mi) and, (2) 22 single-family dwellings with direct access driveways between Yealing Street to Mapes Avenue (0.18 mi). This segment meets the requirement for the CVC 515 "Residence District". Therefore with all these factors, it is recommended that the City establish the segment of Gridley Road a Residence District". This segment does not require continued speed surveys.

SPEED LIMIT CHANGE REDUCE – "SAFETY CORRIDOR", CVC 22358.7(a)(1) JUSTIFICATION:

NF = NON-FRONTING File: Marquardt 2025-32
This section of Marquardt Avenue is a four lane roadway. There is a 45 mph speed limit sign for this segment. The adjacent land uses are residential (non-fronting), and business-industrial. The speed study results show an 85th percentile speed of 46.8 mph which may suggest a 45 mph speed limit. A review collision history revealed that this segment had 2 speed related collisions, 2 collisions involved serious injuries, and 2 collisions involved bicyclist(s), which ranked it as one of the top locations in the City that involved fatality and/or serious injury collisions. In accordance with CVC 22358.7 (a)(1), this segment is designated as a "Safety Corridor" which allows the speed limit to be reduced by 5 mph. Collectively, this segment and other City streets designated as a "Safety Corridor" did not exceed more than 20% of City maintained streets. Therefore, it is recommended to reduce the existing 45 mph speed limit to 40 mph.

This section of Marquardt Avenue is a four lane roadway. There is a 45 mph speed limit sign for the northbound direction only.

The adjacent land uses are residential (non-fronting), and commercial. The speed study results show an 85th percentile speed of

45.6 mph which may suggest a 45 mph speed limit. A review of collision history revealed that this segment had 2 speed related collisions, 1 collision involved serious injuries, and 1 collision involved a bicyclist(s), which ranked it as one of the top locations in the City that involved fatality and/or serious injury collisions. In accordance with CVC 22358.7 (a)(1), this segment is designated as a "Safety Corridor" which allows the speed limit to be reduced by 5 mph. Collectively, this segment and other City streets designated as a "Safety Corridor" did not exceed more than 20% of City maintained streets.Therefore, it is recommended to reduce the existing 45 mph speed limit to 40 mph and post southbound.
