This technical memorandum provides a trip generation and vehicle miles traveled (VMT) screening analysis of the Valley and Willow Warehouses (proposed project), located in the northwest quadrant of the Willow Avenue and Valley Boulevard intersection in the City of Rialto (City).
Per Senate Bill (SB) 743, t he Governor’s Office of Planning and Research (OPR) 1 was directed to amend the California Environmental Quality Act (CEQA) Guidelines to provide an alternative to level of service (LOS) for evaluating transportation impacts. CEQA Guidelines Section 15064.3(b) focuses on specific criteria (VMT) for determining the significance of transportation impacts. Under the new transportation guidelines, LOS, or vehicle delay, does not constitute an environmental impact. Vehicle miles traveled has been adopted as the most appropriate measure of transportation impacts under CEQA.
The City of Rialto has adopted the use of the VMT metric and has significance criteria for transportation impacts related to VMT. Additionally, the City still requires LOS analysis for General Plan consistency requirements . The following analysis has been prepared consistent with the City of Rialto’s Draft Traffic Impact Analysis Guidelines for Vehicle Miles Traveled and Level of Service Assessment (Updated December 2024) which provides guidance on the requirements to evaluate transportation impacts for projects. This analysis was conducted to determine the trip generation estimates and VMT screening analysis of the proposed project and to determine whether a detailed transportation analysis (LOS and/or VMT) would be required for the proposed project. As shown in the screening analysis below, the proposed project would not require a Traffic Impact Analysis (TIA) or further VMT analysis. The City’s Traffic Scope Approval Form to support the LOS and VMT screening is also attached with this memorandum (see Attachment C).
1 Effective July 1, 2024, the Governor’s Office of Planning and Research was renamed the Governor’s Office of Land Use and Climate Innovation (LCI).
This memo has been reviewed and there are no
further comments, Justin P. Schlaefli, PE TE, TKE

SUBJECT:TRIP GENERATION AND VEHICLE MILES TRAVEL (VMT) ANALYSIS FOR THE WILLOW AND VALLEY
WAREHOUSES, CITY OF RIALTO
14204 2 JULY 2025
1.0 Project Description
The project would include construction of two warehouse buildings of approximately 75,109 square feet (SF), (inclusive of 6,400 SF of mezzanine/office spaces), and 46,793 SF ( inclusive of 3,200 SF of mezzanine/office spaces) located in the northwest quadrant of the Willow Avenue and Valley Boulevard intersection. The proposed project would replace 33,000 SF of existing warehouse building and would therefore, result in construction of net new 88,902 SF2 warehouse use on the existing site.
Regional access to the project site is available from Interstate (I) 10 via Riverside Avenue. Additional regional access to the project area is available from I-215 to the east, Foothill Boulevard (Historic Route 66) to the north, and I-15 to the west. The proposed project would be accessed via four driveways - three driveways on the western portion of the site on Willow Avenue, and one driveway on the southern portion of the site on Valley Boulevard. The three western driveways would serve passenger vehic les and trucks and would be full access and the one southern driveway would serve passenger vehicles.
The project would include a total of 116 passenger parking stalls and 12 high dock door parking stalls. The project would provide for adequate parking per City’s municipal code . The site plan of the proposed project includes the detailed parking summary and is included as an attachment (see Attachment A).
2.0 Trip Generation
Table 1 provides a summary of trip generation estimates for the project based on ITE ’s Trip Generation, 11th Edition, for Warehousing use (IT E Code 150). Additionally, the City implements the South Coast Air Quality Management District’s (SCAQMD) recommendation requiring that warehousing use a minimum truck trip rate of 40% of total project traffic. The total percentage of truck trips were further divided by 2-axle, 3-axle, and 4+ axle trucks per current measured rates in the City and provided in the draft TIA guidelines. These truck trips generated by the project were then converted to Passenger Car Equivalent (PCE) trips by using recommended PCE factors.
PCE factors recommended by the City were used to estimate the total PCE trips for the project.

2 The Technical Memorandum and the trip Generation estimates correspond to a higher square footage for the proposed project in the analysis compared to the currently proposed square footage per latest site plan. As shown in Attachment A Site Plan, the revised version of the site plan would result in a total of proposed 119,968 SF and net new 86,968 SF. Therefore, the analysis includ ed in this memorandum and the attached Traffic Scoping Form is conservative.

Notes: TSF = Thousand Square Feet, PCE = Passenger Car Equivalent Some of the totals may not match exactly due to rounding. 1 Trip rates from the Institute of Transportation Engineers, Trip Generation, 11th Edition, 2021. Land Use Code 150 – Warehousing. 2 Per City of Rialto's TIA Guidelines (October 2021), 40% of the daily trips are truck trips (per AQMD staff recommendation included in CalEEMod v. 2013.2 Appendix E Technical Source Documentation, Fleet Mix) for warehousing uses i.e. ITE Code 150. The vehicle mix for trucks i.e. 2-axle, 3-axle, and 4+ axle trucks are per current measured rates in the City and provided in the draft TIA guidelines.
3 Passenger Car Equivalent (PCE) factors are assumed to be 1.0 for passenger vehicles, 1.5 and 2.0 for 2 -axle and 3-axle trucks, and 3.0 for 4-axle trucks per City of Rialto TIA Guidelines (October 2021) The existing warehouse on the project site would be replaced by the proposed project, therefore, the trip generation was estimated for the net new proposed use i.e., approximately 88,902 SF of warehouse use. Because the existing uses are currently operational, an existing use trip credit was applied to estimate the project’s net new trip generation. As shown in Table 1, the proposed project would generate approximately 152 net new daily trips, with 15 net new trips (12 inbound and 3 outbound) in the AM peak hour, and 16 net new trips (4 inbound and 12 outbound) in the PM peak hour. Adjusting for PCE, the trip generation is approximately 255 net new daily PCE trips, 23 net new AM PCE peak hour trips ( 18 inbound and 5 outbound) and 24 net new PM PCE peak hour trips ( 10 inbound and 14 outbound). Separate tables for the project’s existing, proposed and net trip generation are provided in Attachment B.
3.0 LOS Screening Analysis
Per City’s TIA Guidelines (Updated December 2024), the proposed project would not generate 50 or add more AM or PM peak hour trips to the existing circulation system. Figures 1, 2a and 2b illustrating the project’s trip distribution and assignment are provided in Attachment B. There are no other operational concerns in the vicinity of the project site known at the time of this writing. Therefore, the proposed project would not require a quantitative LOS analysis. Attachment C includes the City’s Traffic Scoping Form to support exemption from LOS analysis.

4.0 VMT Screening Analysis
The Governor’s Office of Planning and Research (OPR) prepared a comprehensive update to the CEQA Guidelines in 2017 that were approved by the California Natural Resources Agency in December 2018, requiring that lead agencies use VMT for analyzing transportation impacts. CEQA Guidelines Section 15064.3 states that “generally, vehicle miles traveled (VMT) is the most appropriate measure of transportation impacts,” and define VMT as “the amount and distance of automobile travel attributable to a project.” Note that “automobile” refers to on -road passenger vehicles, specifically cars and light trucks. Heavy -duty truck VMT does not need to be included in the analysis per SB 743 requirements. Other relevant considerations may include the effects of the project on transit and non-motorized traveled.
The OPR’s Technical Advisory suggests that agencies may screen out VMT impacts using project size, maps, transit availability, and provision of affordable housing. The guidance recommended by OPR has been used by the City to be better suited to the local and sub -area conditions of Rialto within the San Bernardino County . The proposed project would be screened out using the City’s low VMT area criterion for screening, as discussed below.
Per OPR’s Technical Advisory and City of Rialto's TIA Guidelines, if a project generates less than 110 daily trips (from passenger vehicles), it can be screened out from conducting a VMT analysis, using the Small Project Screening criteria. Using the ITE Trip Manual, 11th Edition, as shown in Table 1, the project would generate a total of 125 daily passenger vehicle trips or 91 net new daily passenger vehicle trips, therefore can be potentially screened out using the Small Project Screening criteria when applied to net new daily trips . However, because the proposed project generates 125 daily trips under the proposed conditions, it doesn’t adequately meet the threshold of 110 daily trips or less to use Small Project Screening criteria.
Per City’s TIA guidelines, residential and office projects located within a low VMT-generating area may be presumed to have a less than significant impact absent substantial evidence to the contrary. In addition, other employment- related and mixed -use land use projects may qualify for the use of sc reening if the project can reasonably be expected to generate VMT per capita or per employee that is consistent with the existing land uses in that low VMT generating area. The City’s guidelines recommend using pr oduction-attraction (PA) VMT when there is a need to isolate home-based work VMT for the purposes of isolating commute VMT. Because the project is primarily an employment-based use, it is acceptable to use PA VMT for determining the project’s VMT screening using the SBCTA VMT E valuation Tool. The project is consistent with existing industrial land uses in its vicinity and is therefore consistent with VMT analysis provided by the tool.
As shown in Table 5. Project VMT Summary, the jurisdiction baseline PA VMT per worker is 16.9 and the threshold is 16.9 or below. It should be noted that the recommended threshold for the County is 32.7 VMT per service employee. Service population is a total of residents and employees or workers in a zone. The project’s service population consists of only workers; therefore, the project’s PA VMT per worker if compared to the threshold of VMT per service population would be significantly lower. As the proposed project would not exceed the PA VMT baseline of 16.9 and would be significantly below 32.7 VMT per service population, it would be screened out using the SBCTA VMT Evaluation tool. The project’s VMT would result in a less than significant impact.

Source: Attachment D
Notes: VMT = vehicle miles traveled, TAZ = Traffic Analysis Zone Per the City’s TIA Guidelines (City of Rialto 2024) and for purposes of compliance with Senate Bill 743, a detailed VMT analysis is not required for the proposed project.
5.0 Conclusions
Based on the trip generation analysis above, the proposed project would generate less than 110 daily net new passenger vehicle trips. The proposed project is consistent with the existing uses and is located in a low VMT generating zone per SBCTA VMT Evaluation Tool using the selected VMT per worker metric. Per the City’s TIA guidelines, the proposed project would be screened out from conducting further VMT analysis and presumed to have a less than significant VMT impact. Thus, the project would not require any mitigation.
Based on the trip generation analysis above, adjusting for PCE, the project would generate approximately 23 net new AM PCE peak hour trips (18 inbound and 5 outbound) and 24 net new PM PCE peak hour trips (10 inbound and 14 outbound). Per the City’s TIA guidelines and project’s trip generation estimates , the proposed project would not be required to prepare a LOS analysis.
