DETAILED SCOPE OF WORK
TASK 1 TRAFFIC FORECASTS DEVELOPMENT
Consultant shall develop the traffic forecasts along Avenue G and in the northern portion of Lancaster using Southern California Association of Governments (SCAG)’s 2024 Regional Transportation Plan/Sustainable Community Strategy (RTP/SCS) travel demand model.
Traffic forecasts for study locations will be developed through application of a post-processing methodology that uses the difference method, consistent with the National Cooperative Highway Research Program Report (NCHRP) 765: Analytical Travel Forecasting Approaches for Project Level Planning and Design (Transportation Research Board, 2014) methodologies.
The SCAG 2024 RTP/SCS model has a 2019 Base Year and a 2050 Future Year. The model roadway network in the study area will be reviewed to confirm that the base and future year models reflect the existing roadway network, and any improvements planned by the City of Lancaster and in SCAG’s 2024 financially constrained RTP. The Consultant shall review land uses in the study area and coordinate with the City to ensure that the planned industrial and warehouse land use developments are included in SCAG future year model. The Consultant shall re-run the SCAG future year model to account for identified transportation and land use projects.
The AM and PM peak hour and daily traffic volume forecasts will be developed at the study intersections listed below. The cost estimate includes 21 study locations.
The traffic forecasts will be developed for both personal auto and heavy- duty truck vehicles.
The Consultant shall collect existing turning movement volumes for both autos and trucks at the study intersections to have an accurate baseline count. The Consultant will already have traffic counts at six of the study intersections on Avenue F and Avenue G that the Consultant collected for nearby projects in 2023 and 2024, and the Consultant shall collect new traffic counts at the remaining 15 study intersections during the AM peak period (7:00-9:00AM) and PM peak period (4:00-6:00PM) as part of this study. The Future Year (2050) forecasts will be developed by applying the growth calculated from the Base Year and Future Year models to the existing traffic volumes. Interim year forecasts (e.g., Year 2030) will also be developed by interpolating between the existing and Future Year volumes, if needed.
Task 1.2 – Additional Freight Forecasting
In addition to the peak hour intersection forecasts in Task 1, the Consultant shall provide daily traffic volume forecasts and additional freight related data as described below:
Service Group Category 2 (Reference RFQ 769-22)
Traffic Engineering for
SR-14 (SR-138)/Avenue G Interchange Project Readiness Studies (Reference: PWCP 13-020)
Exhibit 1, Page 4 of 9
• Consultant shall forecast daily heavy duty truck volumes on Avenue G and on the adjacent corridors of Avenue D, Avenue E, Avenue F, Avenue H, and SR-14 for Year 2050 using the SCAG model.
• Consultant shall collect existing daily roadway classification counts for the five corridors listed above (24-hour count on a weekday).
• Consultant shall estimate the growth in truck trips with an origin/destination in the Antelope Valley between 2019 and 2050 conditions using the SCAG model. • Consultant shall use socio-economic data from the SCAG model to report the number of jobs associated with industrial land uses in the Antelope Valley for 2019 and 2050.
This data will reflect recently approved and pending projects in the City of Lancaster (Task 1 includes updating the model to reflect these projects). • Consultant shall utilize other big data sources to obtain data on truck origins - destinations in the broader study area. Since the SCAG model ends at the Los Angeles County line, this data will be helpful to understand truck activity associated with Kern County.
• Consultant shall coordinate internally on SCAG model assumptions and factors relating truck payloads and truck trips to the employment types and groups used in the SCAG model to help provide estimates of potential commodity flow/freight volumes for the Avenue G study area.
Task 1.3 Technical Memorandum
The methodology and traffic forecasts results outlined above will be documented in a technical memorandum that will be provided to the project team for review. The Consultant shall respond to one round of comments and submit the final memorandum.
Task 1 Deliverables
• One (1) Draft Traffic Forecast Technical Memorandum
• One (1) Final Traffic Forecast Technical Memorandum
Task 1 Critical Path
Caltrans is currently constructing improvements along SR-14, which have ramps and mainline lanes closed. This task cannot begin until traffic control and lane closures are cleared from all intersections listed in Task 1.1 so that accurate count data can be obtained.
Task 1 Payment
Payment for Task 1 shall be at the lump sum price as shown on Exhibit 3. Such payment shall be considered full compensation for furnishing all labor, equipment, materials and incidentals for performing Task 1 as required in this Scope of Work.

TASK 2 PROJECT SCOPE VALIDATION
Consultant shall validate the Project design based on updated traffic forecasts and current standards.
Task 2.1 Traffic Validation
Consultant shall use the updated traffic forecasts completed in Task 1 to assess and validate the design of the preferred alternative.
A Synchro model will be developed to evaluate the 2050 traffic operations at all study intersections in the build scenario only. Existing and 2050 No-build analysis will not be conducted. The AM/PM peak hour analysis in Synchro will be used to assess whether the proposed improvements will still provide satisfactory operations (LOS D or better). If operations with the new 2050 forecasts show any operational deficiencies in the intersection analysis, the analysis will also evaluate what additional improvements are needed to operate at LOS D or better.
The findings will be documented in a brief technical memorandum. It is assumed that no revisions to the analysis or technical memorandum will be required.
Task 2.2 Design Validation
Consultant shall use the traffic validation completed in Task 2.1, along with the freight forecasting completed in Task 1.2, to validate the design of the preferred alternative. It is assumed that the updated traffic analysis will inform at a high level if there is a need to incorporate additional improvements to address any design deficiencies due to the updated traffic forecasts.
Additionally, the preferred design approved in the Project Report will be compared to the latest version of the 7th Edition of the Highway Design Manual (HDM), last updated on 8/8/2025. Any design revisions required due to changes in the HDM will be noted for discussion with the City.
Because the extent of required design revisions will be determined at this time, the scope of work and associated fee required for this effort will be reassessed during this discussion.
A concept drawing will be prepared for review by the City. It is assumed that a fully developed Caltrans Geometric Approval Drawing (GAD) will not be required at this time. One round of consolidated comments will be incorporated into a final concept drawing.

Exhibit 1, Page 7 of 9
Task 3.2 Economic Impacts Estimation
The Consultant shall evaluate a range of potential economic impacts related to new logistics and industrial development in the Avenue G Corridor/Fox Field Industrial Corridor. These will include:
• Job creation by industry and occupation
• Wages associated with new jobs
• Municipal tax revenue (e.g., property tax, sales tax) generated by new uses The Consultant shall rely on public and proprietary data sources to estimate the above impacts and will build on its previous analysis of employment dynamics in the City to demonstrate the capacity for the City’s existing resident workforce to fill new jobs, and any projected growth in in- commuting associated with these jobs.
The additional freight forecasting completed in Task 1.2 will be utilized to analyze the growth in heavy duty truck traffic and associated volume of goods generated by new logistics and industrial development in the Corridor as it pertains to economic impacts.
The Consultant shall apply gathered data on site location criteria for new industrial and logistics development, including physical site characteristics that developers and operators prefer, to the parcels in the Avenue G Corridor/Fox Field Industrial Corridor to comment on the relative appropriateness and attractiveness of the sites for this new development. Relevant GIS data will be requested from the City to facilitate this review.
Task 3.3 Evaluation of Additional Impacts
The Consultant shall consider other economic impacts related to the proposed improvements at the Avenue G and SR-14 interchange. This evaluation will build on the previous work completed for the City reviewing commute patterns and industry growth trends. Specifically, the following evaluations will be completed:
• Commute Patterns: Data will be collected on the number of residents commuting out from the areas surrounding the Avenue G Corridor, as well as the number of workers commuting into the area, using Census sources. This information will indicate the volume of commuters using the Avenue G/SR-14 interchange who would be positively impacted by the interchange improvements.
• Impacts on Other Industries and Related Job Growth: Data will be collected on industries projected to grow in the City and neighboring communities, as well as the County, over the next ten years.
