RE: Proposal to Conduct 2025 Citywide Engineering and Traffic Survey
Dear Ms. Abston:
In response to the City’s Request for Proposal (RFP) dated October 4, 2024, AGA Engineers, Inc. (AGA) is pleased to present to you this Technical Proposal to provide an Engineering and Traffic Survey (E&TS) for 207 locations in the City of Santa Clarita. As directed in the RFP, our Cost File and required forms are being submitted to BidNetDirect as separate files.
We believe that AGA is a highly qualified and innovative firm that possesses all of the necessary capabilities to complete the proposed project in a professional, timely, and cost-effective manner. AGA staff completed the previous City of Santa Clarita Speed Survey projects (2000, 2003, 2005, 2012, and 2018) and also have extensive experience in completing similar E&TS projects for several cities in Southern California.
AGA also believes that for the safety of the travelling public and the residents, the City should consider the provisions of California Assembly Bill 43 (AB 43) which now provides the Cities more authority to reduce speed limits on roads, including state highways.
We fully understand the very important legal aspects involved in this project. The product of the study will be a legal document which will be acted upon by the City Council to formally adopt and/or change specific speed limits at the surveyed locations. The report will be the document used by both the Los Angeles County Sheriff’s Office and the local courts in the day -to-day legal defense activities of the established speed limit.
The AGA Team will be headed by Mr. Ruben Perales, PE, TE, Vice President, who will serve as Project Manager and be the City’s main contact for the project. He has managed many other E&TS projects for several agencies and as a result of this experience, he fully understand s the importance of dealing with traffic-related situations, including determining the appropriate posted speeds along city corridors. Mr.
Perales’ contact information is shown below:

2025 Citywide Engineering & Traffic Survey
Introduction and Qualifications of Firm
Introduction
The City of Santa Clarita is seeking a traffic engineering consultant to conduct a citywide Engineering and Traffic Survey (E&TS) in order to comply with the California Vehicle Code (CVC) and the California Manual on Traffic Control Devices (CA MUTCD) to e stablish or update speed limits on the City’s streets. Our proposed approach for this project, over and above complying with the specific relevant requirements of the CVC and of the CA MUTCD for Streets and Highways, will be to:
• Meet with City staff and discuss the project completely, including any scheduling and other staff concerns.
• Conduct field radar surveys under free flow traffic conditions only, using a certified radar technician specializing in these tasks, with both personnel and equipment certified to conduct the surveys.
• Conduct field review of all street segments to determine roadway description, adjacent land use, roadway geometrics, and conditions not readily apparent for justification of speed limits. • Evaluate speed limits by reviewing current traffic count data, a minimum of two years of accident history (Crossroads) at mid-block locations, in conjunction with the speed survey data.
The objective of the proposed project is to review the existing speed limits to validate and/or recommend changes to the speed limits (increase, decrease, or no change) in accordance with the requirements of the State of California, Department of
Transportation, CA MUTCD, Part 2B.13 (Speed Limit Sign), and CVC 627 and 40802, and sections 22348 through 22413. The study will provide sufficient information to document that the conditions of the latest edition of CVC Section 627 have been satisfied and that oth er conditions not readily apparent to a motorist are properly identified. The project will also adhere to the latest California Manual for Setting Speed Limits. To legally use radar for speed enforcement, the changes must be justified by an engineering and traffic survey conducted within five years prior to the date of the alleged violation or seven years if an extension has been applied.
It is important to note that the recently adopted Assembly Bill No. 43 (AB 43) amended and added sections to both the CVC and the latest version of the California Manual on Uniform Traffic Control Devices (CA MUTCD) related to traffic safety and speed limits. The following are key highlights:
• Allows prima facie speed limit of 25 mph on State highways located in any business or residential district.
• Authorizes Caltrans and a local authority to declare a speed of 20 or 15 mph on State highways. • Authorizes a lower speed limit on a section of highway contiguous to a business activity district.
Definition of “business activity district” is identified in AB 43 text.
2025 Citywide Engineering & Traffic Survey
• Authorizes a local authority to further reduce the speed limit beyond the 5 -mph reduction after June 30, 2024, if certain conditions are met.
• Extends the validity of speed surveys from 10 years to 14 years if evaluated by registered engineer. • Local authority may, by ordinance, retain the current speed limit or restore the immediately prior speed limit if that speed limit was: (1) established with an engineering and traffic survey, and (2) if a registered engineer has evaluated the section of hi ghway and determined that no additional general purpose lanes have been added to the roadway since completion of the traffic survey that established the prior speed limit.
The product of the study will be a legal document which will be acted on by the City Council to formally adopt and/or change specific speed limits at the surveyed locations. The report will be the document used by both the Los Angeles County Sheriff’s Department and the local courts in the day-to-day legal defense activities of the established speed limit.
The following pages outline our project approach, methodology, and the Team’s specific experiences and technical competence in more detail, along with references and representative projects in the order specified by the RFP.
Qualifications of Firm
AGA Engineers, Inc. (AGA) is a California S Corporation with 17 employees, many of whom have worked together for at least five years and the executives have worked together for over 20 years, which is a respectable indication of the stability and compatibility of our team.
AGA was founded in 2020 by Mr. Chalap K. Sadam, former Vice President and co-founder of Albert Grover & Associates, which was founded in 1993. The new company was formed after the passing of the founder and CEO, Mr. Albert Grover. After acquiring certain assets from Albert Grover & Associates, and under the leadership of Mr. Sadam, AGA has retained a similar culture and the practices that made our transition seamless to all our clients – largely due to retention of our core team of senior and professional staff who worked under the former company. Our engineers bring more than 30 years of expertise and experience to AGA allowing us to continue to successfully work for our clients.
All work performed under this contract with the City will be conducted by employees located at AGA’s offices in Fullerton. AGA and our subconsultant, National Data & Surveying Services (NDS), have the resources to perform all of the tasks listed in the Request for Proposals (RFP).
AGA is a multidiscipline engineering firm specializing in municipal and transportation engineering.
Through utilization of today’s most sophisticated, computer -aided equipment by highly skilled and talented professional engineers and technicians, we are able to provide clients with quality, cost-effective, professional services in a timely manner.

the planning and conceptual design stage through the construction supervision and “as -built” stage, placing us among the forerunners in the full-circle service concept.
AGA’s wide range of services offered can be divided into six primary areas of expertise: traffic engineering, day-to-day traffic signal operations, transportation planning, traffic signal communication design, operational control of traffic signal systems, and City Traffic Engineer staffing. While we are well known and respected for our work in all of these areas, we are perhaps best known for our widespread knowledge and
experience in the field of multijurisdictional traffic signal design and coordination. It should also be noted that AGA operates over 200 traffic signals on behalf of five jurisdictions in Southern California. Those traffic signals are remotely monitored and controlled from the Traffic Management
Center located in AGA’s Fullerton office.
From installing the first flashing yellow arrow projects in Southern California, to ground -breaking bicycle boulevard projects, to unique traffic calming and school zone safety projects, our team is committed to finding the best solution to complex traffic and transportation challenges for our clients. This more comprehensive view of our roles as traffic engineers, planners, and technicians has evolved from the cumulative individual experiences of our staff while employed at various public agencies. The City will be hard pressed to find another consultant with such far -reaching municipal traffic engineering, traffic operations, and transportation planning experience in Southern California.
Our approach to providing professional services and projects is to do more than simply provide labor or prepare design plans and study reports – we actually improve traffic operations and safety in everything we touch. AGA is not a company that simply provides engineering labor to complete client designated tasks; rather, AGA provides a high level of intellectual support to accomplish client objectives. AGA’s unique blend of Civil Engineers, Traffic Engineers, and skille d traffic signal system and communica tions technicians provides a synergy which results in successful projects beyond client expectations.
Previous Experience
We fully understand the importance of dealing with traffic-related situations, including determining the appropriate posted speeds along the City’s corridors. Staff at AGA have completed many tasks similar or identical to those anticipated under this contract, and have completed such tasks on time, within budget, and in a manner that meets all the requirements of the agency for which the work was completed, while at the same time placing minimal time and effort requirements on agency staff.

Scope of Work and Methodology
Based on our extensive experience in conducting E&TS for various agencies throughout the years, the following is the AGA Team’s scope of work for the project.
All work under this contract will be performed under the direction and supervision of a qualified Registered Civil Engineer/Traffic Engineer licensed in the State of California.
Task 1 – Kick-Off Meeting
AGA will coordinate and conduct a kick-off meeting at City Hall with both City and Police Department staff.
At this meeting, the project objectives will be clarified, the project schedule will be finalized, and specific requirements will be discussed. The City will provide Average Daily Traffic (ADT) counts, the most current collision history (two years), and any other pertinent data needed for analysis.
AGA will prepare and distribute an agenda prior to the meeting and submit meeting minutes and a participant list within a week after the meeting.
Task 2 – Accident Rate Analysis
Using the City -provided ADT counts and accident data, AGA will conduct an analysis of the Accident Rate. For collision history analysis purposes, only mid-block collisions are used. Mid-block collisions are defined as those occurring outside of the 150-foot radius of signalized intersections near the roadway segment being analyzed. This criterion excludes collisions that may be traffic signal related in nature. The mid-block collision rate in terms of “collisions per 1,000,000 vehicle miles of travel” for e ach segment surveyed will be calculated and shown on the Engineering and Traffic Survey summary sheets.
The following shows the collision rate calculation:
Collision Rate = Number of Midblock collisions x 106
24-hour volume x 365 x segment length x number of years Where:
• Number of mid-block collisions based on a minimum of three years • 24-hour volume (both directions) for the survey segment • Segment length in miles
A minimum of two years of collision data will be utilized to develop Actual Collision Rates for comparison to the Average Expected Collision Rates which is detailed in the 2021 Crash Data on California State Highways published by the California Department of Transportation. The Average Expected Collision Rates per roadway type are summarized below:
2025 Citywide Engineering & Traffic Survey
Roadway Type Average Expected
Collision Rate
Conventional 2 lanes or less (< 45 mph) 1.07
Conventional 2 lanes or less (> 45 mph) 0.61
Conventional 3 lanes 1.61
Undivided 4 lanes (<45 mph) 0.66
Undivided 4 lanes (> 45 mph) 0.77
Divided 4 lanes (< 45 mph) 0.64
Divided 4 lanes (> 45 mph) 0.93
Divided 5 lanes or more (< 45 mph) 0.75
Divided 5 lanes or more(> 45 mph) 0.87
Task 3 – Field Review
A licensed Traffic Engineer will review all project segments to determine any roadway conditions not readily apparent to motorist s which would justify changing the proposed speed limit to the maximum permitted under State established guidelines. These characteristics include but are not limited to the following:
• Street width and alignment • Traffic flow
• Channelization and striping patterns • Frequency of driveways • Reversed super elevation • Visibility obstructions
• Roadside land use • Roadway grade
• Heavy pedestrians and/or trucks • On-street parking
The product of this review will be a summary of each of the segments and identification of the segments which justify consideration for maximum increase/decrease of the recommended speed limits. In addition to reviewing the roadway conditions not readily apparent to motorists, the AGA team will review the locations of existing speed limit signs and will provide recommendations on any relocations or additions of speed limit signs.
Task 4 – Spot Speed Surveys
The vehicle speed surveys will be conducted in accordance with the 2020 California Manual for Setting Speed Limits published by the Division of Traffic Operations of the California Department of Transportation, the CA MUTCD, and the CVC. AGA’s subconsultant, NDS, will be conducting radar speed surveys for all 207 segments. In addition, an allocation for an additional 15 segments 2025 Citywide Engineering & Traffic Survey
A minimum of 100 bidirectional speed observations, with a minimum of 50 observations for each direction of travel, will be obtained for the designated city street segments. Obtaining a minimum of 100 speed samples for each street segment will ensure that there will be a 95% probability that the sample data represents the population data for this type of study and the actual behavior of the majority of motorists. For higher volume segments, a minimum of 200 bidirectional speed observations will be obtained.
The studies will only be conducted during “good weather” conditions on weekdays (Monday – Thursday) during the off -peak hours of 9:00 AM to 4:00 PM when school is in session, unless other specific time limits are specified by the City. Each speed zone will be surveyed for representative free flow speeds; that is, speeds not influenced by temporary conditions or construction work . The survey will utilize a traffic radar/laser gun which is calibrated and certified periodically to achieve and maintain accuracy.
The field survey data will be marked on a radar speed survey field sheet and will contain the following roadway segment information:
• Adjacent land use types • Lane configuration
• Roadway geometrics • Median type
• On-Street Parking • No Parking/Stopping restrictions
• School Zone • Truck Route
• Bike Route • Bike lane facilities
• Pedestrian and bicycle activity • General Comments
Task 5 – Prepare Draft Engineering and Traffic Survey Report
After compiling all pertinent data on the Segment Spot Speed Summary Table, and the Engineering & Traffic Survey Sheets for all project segments, AGA will submit all survey sheets to the City for review. AGA will discuss the findings with City staff and will review any comments/questions City staff may have on recommendations shown on the survey sheets. The latest edition of the CA MUTCD (Revision 8) includes guidelines to assist with the designation of such corridors.
A draft report documenting the Engineering and Traffic Study will be submitted to the City for review. It will summarize the existing speed limits and the recommended changes (increase, decrease, or no change) in accordance with the requirements of CVC Sec tions 627, 40802(b), 22357, 22358, and AB 43 (included in the CVC). AGA will also document any changes in the guidelines based on the current California Manual for Setting Speed Limits and the current CA MUTCD, if any.
2025 Citywide Engineering & Traffic Survey
Task 6 – Final Engineering and Traffic Survey Report
The report will be a legal document to formally adopt or change speed limits at the surveyed locations. It will include an executive summary, a summary of recommendations in a tabular format for ease of reference, specific recommendations with a description of the basis for that recommendation for each roadway segment surveyed, and all other supporting data.
At a minimum, the report will include the following:
• Radar speed survey operational procedures
• Description of the purpose and methodology of Speed Zone establishment, including a discussion of realistic speed zoning, speed traps, CVC requirements, etc. • Description of the statistical analysis factors
• Description of the field data used in analyzing related roadway characteristics • Collision history for the street segments
• Results and recommendations
• Summary of recommendations in both narrative and table form
As an added value to the City of Santa Clarita, AGA will prepare a citywide ADT map and citywide speed map to summarize the data. A sample of this ADT map and Speed Map is included as an attachment.
A meeting with City staff will be held to discuss the analysis results presented in the Draft E&TS Report.
AGA will address and incorporate the City’s consolidated comments on the draft report into the final report which will be provided to the City in both hardcopy and electronic formats. Another meeting with City staff will be conducted for the presentation of the Final E&TS Report.
A final signed original and ten signed copies of the Final E&TS Report will be submitted to the City.
Traffic Commission and City Council Meetings
AGA will be available to attend one Traffic Commission meeting and one City Council Meeting to assist City staff with presenting the speed survey results. We will also respond to any questions that Commission/Council members may have.
